Abstract

The present invention relates to a large parasol and, more particularly, to a large parasol having a special waterproof cloth to sun shade to constitute a general weatherproof cloth as awning screens to resolve a problem of lifetime shortening due to discoloration in long-term use since color fastness to light of the conventional awning screen made of a common waterproof cloth was less effective. The large parasol is configured to enhance the UV blocking effect while enhancing the water pressure characteristic, and increase flame resistance to enhance safety against fire risk since a parasol is often used in the summer months when the UV index is high.

Description

대형 파라솔{Large parasol}Large parasol {Large parasol}

본 발명은 대형 파라솔에 관한 것으로, 보다 상세하게는 특수 방수천으로 차양막을 구성하여 일반 방수천으로 구성된 종래 차양막의 일광견뢰도가 떨어져 장기간 사용시 변색에 의한 수명단축의 문제를 해소할 수 있을 뿐만 아니라, 자외선 지수가 높은 하절기에 주로 사용되는 파라솔이라는 특성상 자외선 차단 효과도 높이면서 내수압 특성을 강화시켜 방수성을 증대시키고, 나아가 방염성도 증대시켜 화재위험으로부터 안전성을 강화시킨 대형 파라솔에 관한 것이다.More particularly, the present invention relates to a large parasol, and more particularly, to a sun shade having a special waterproof cloth to constitute a general weatherproof cloth. Thus, the conventional sun shade has a low light fastness to light and can solve the problem of shortening the life time due to discoloration during long- The present invention relates to a large parasol which enhances the ultraviolet ray shielding effect by enhancing the water pressure property by enhancing the waterproofing property, and further enhancing the flame resistance, thereby enhancing the safety from the fire risk, due to the parasol which is mainly used in the summer when the ultraviolet ray index is high.

일반적으로 파라솔은 햇빛을 막아주어 한여름 자외선 차단에 효과적이며, 주로 정원, 테라스, 해변 등에서 사용함은 물론 테이블과 함께 두고 사용하여 카페 분위기를 연출하기도 한다.In general, parasol blocks sunlight and is effective in blocking summer sunlight. It is used mainly in garden, terrace, beach, etc., and it is used with table to direct the cafe atmosphere.

파라솔은 비교적 크기가 작은 이동형 파라솔과 크기가 큰 대형 파라솔로 구분되며, 특히 대형 파라솔의 경우에는 지면에 직접 고정되고 견고한 프레임체로 이루어져 있으므로 보다 대형으로 제작할 수 있어 내부의 수용공간이 비약적으로 증대되므로 각종 행사를 진행하거나 각종 작업 등을 그 내부에서 할 수 있는 것이다.The parasol is classified into a relatively small size movable parasol and a large size parasol. Especially, in the case of a large parasol, since the parasol is fixed directly on the ground and is made of a rigid frame, it can be manufactured in a larger size, It is possible to carry out an event or to carry out various kinds of work from inside.

통상의 대형 파라솔은 지면에 고정되는 것이므로 이동성을 고려하지 않기 때문에 차양막을 절첩하거나 전개하기 위한 별도의 지지대 절첩구조를 채택하지 않는 것이 일반적이다.Since the ordinary large parasol is fixed to the ground, mobility is not considered, and therefore, it is general not to employ a separate support folding structure for folding or expanding the shade film.

따라서, 대형 파라솔은 한번 설치된 상태에서는 그 파라솔을 해체하기 전까지 늘 전개된 상태를 유지하게 되는데, 이렇게 전개된 상태를 유지하는 경우에는 폭우나 폭설 또는 강풍을 만나는 경우 그 지지대 및 지지기둥이 파손 및 훼손되는 문제점이 있기에 파라솔을 접어서 보관하는 것이 바람직하다.Therefore, when a large parasol is installed, the parasol is always deployed until it is dismantled. If the parasol is deployed in such a state, if it is exposed to heavy rain, heavy snow or strong wind, the support and supporting columns are damaged or damaged It is desirable to fold the parasol and store it.

이러한 기술의 일예가 하기 [선행기술 1]에 개시되어 있다.One example of such a technique is disclosed in the following [Prior Art 1].

[선행기술 1]에는 바닥에 고정되는 한쪽 끝부분으로부터 소정의 높이로 형성된 고정부와 상기 고정부의 위쪽 끝부분은 소정의 각도로 굽어져 아암 형상으로 형성된 아암부와 상기 아암부의 끝부분에서 아래쪽으로 수직으로 굽어진 수직부가 형성된 기둥과 상기 기둥의 수직부에 고정되며 지붕살과 작동살로 이루어져 접철가능하게 설치되는 지붕과 상기 기둥 및 지붕에 연결되어 설치되고 상기 지붕을 접고 펼치기 위한 접철장치를 포함하는 파라솔에 있어서, 상기 아암부의 일단이 접힐 수 있도록 경첩부재로 이루어져 있고 상기 지붕에 형성된 지붕살의 일단에 힌지 결합되는 제1지지살과 상기 작동살의 일단에 힌지 결합되는 제2지지살과 상기 제1지지살과 제2지지살을 연결 및 회동 가능하게 힌지부재가 형성된 것을 특징으로 하는 파라솔에 대해 개시되어 있다.[Prior Art 1] includes a fixing portion formed at a predetermined height from one end portion fixed to the floor and an upper portion of the fixing portion bent at a predetermined angle to form an arm portion, And a folding unit fixedly connected to the vertical portion of the pillar and being foldably connected to the pillar and the roof, and a folding device connected to the pillar and the roof to fold and unfold the roof A first support piece hinged to one end of a roof fence formed on the roof and a second support fingers hinged to one end of the operation fingers and a second support piece hinged to one end of the roof fence, Characterized in that a hinge member is formed in such a way that the support piece and the second support piece are connected and rotatable There is.

그러나, 상술한 종래의 기술은 지붕을 접은 상태에서 아암부의 일단을 접을 수 있도록 접철장치에 형성된 레칫을 잠금키로 고정시킨 상태에서 경첩부재의 바디를 사용자가 직접 이동하여 상측으로 올리면 제1지지대에 형성된 걸림턱과 헤드의 하단에 형성된 고정홈이 분리되어 제1지지부와 제2지지부재가 서로 회동 가능하게 되는 것이다. However, in the above-described conventional technique, when the body of the hinge member is directly moved by the user in a state where the ratchet formed on the folding device is fixed by the lock key so that one end of the arm portion can be folded while the roof is folded, The engaging jaw and the fixing groove formed at the lower end of the head are separated so that the first supporting portion and the second supporting member can be rotated with respect to each other.

따라서, 종래의 기술은 경첩부재를 작동시키기 위하여 사용자가 직접 이동해서 힘을 가하기 때문에 불편함이 있을 뿐만 아니라 크기가 대형이기 때문에 신체가 작은 사용자에 의한 조작이 어렵다는 문제점이 있었다.Therefore, the conventional art has a problem in that it is difficult for the user to operate the hinge member because the user directly moves and applies the force.

이를 개선하기 위해 [선행기술 2]가 개시된 바 있다.To improve this, [Prior Art 2] has been disclosed.

그런데, 상기 [선행기술 2]는 일반적인 방수천으로 차양막을 구성하고 있어 일광견뢰도가 떨어지기 때문에 장기간 사용시 변색에 의한 수명단축의 문제가 있을 뿐만 아니라, 방염성이 없어 이에 대한 개선이 요구되고 있다.[Background Art] [Prior art 2] has a problem that the life time is shortened due to discoloration at the time of use for a long period of time because of a low water fastness due to the deterioration of the light fastness due to a general waterproof cloth.

뿐만 아니라, 자외선 지수가 높은 하절기에 주로 사용되는 파라솔이라는 특성상 자외선 차단 효과도 높아야 하지만, 현재까지 개시된 파라솔들은 대부분 차양막 이외의 특별한 기능이 구현되어 있지 않아 이 또한 개선이 요청되고 있는 사항이다.In addition, the ultraviolet ray shielding effect should be high due to the nature of parasol, which is mainly used in the summer when the ultraviolet ray index is high. However, most of the parasols disclosed so far have not been provided with special functions other than the sunglasses.

또한, 일반 방수천의 내수압 특성은 방수성이 좋은 텐트 원단을 기준으로 볼 때 대략 2000mm 전,후인 바, 이 경우에는 폭우가 집중적으로 지속될 때 방수성이 떨어지기 때문에 이에 대한 보완도 요구되고 있다.In addition, the waterproofing property of the general waterproof cloth is required to be supplemented because the waterproofing property is degraded when the rainwater intensively continues in the case of the waterproof tent cloth about 2000 mm before and after the rainbow bar.

이하에서는, 첨부도면을 참고하여 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명 설명에 앞서, 이하의 특정한 구조 내지 기능적 설명들은 단지 본 발명의 개념에 따른 실시예를 설명하기 위한 목적으로 예시된 것으로, 본 발명의 개념에 따른 실시예들은 다양한 형태로 실시될 수 있으며, 본 명세서에 설명된 실시예들에 한정되는 것으로 해석되어서는 아니된다.Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

또한, 본 발명의 개념에 따른 실시예는 다양한 변경을 가할 수 있고 여러 가지 형태를 가질 수 있으므로, 특정 실시예들은 도면에 예시하고 본 명세서에 상세하게 설명하고자 한다. 그러나, 이는 본 발명의 개념에 따른 실시예들을 특정한 개시 형태에 한정하려는 것이 아니며, 본 발명의 사상 및 기술 범위에 포함되는 모든 변경물, 균등물 내지 대체물을 포함하는 것으로 이해되어야 한다.In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

본 발명에 따른 대형 파라솔은 기둥이 바깥쪽에 위치하여 공간 활용을 최대화할 수 있고, 또한 사용하지 않을 때는 접을 수 있어 간편하고 공간을 많이 점유하지 않는 장점이 있다.The large parasol according to the present invention is advantageous in that it can maximize the space utilization by positioning the column at the outer side and can be folded when not in use, so that it does not occupy much space.

뿐만 아니라, 본 발명에 따른 대형 파라솔은 햇빛의 방향에 따라 360°회전할 수 있도록 구성되어 있기 때문에 그늘 면적을 최대화시키는 효율적인 구조를 갖추고 있으며, 더욱 강력한 프레임과 우산살 보강으로 강풍에도 견딜 수 있게 견고히 구성된다.In addition, since the large parasol according to the present invention is configured to rotate 360 ° according to the direction of the sunlight, it has an efficient structure that maximizes the shade area, and a stronger frame and umbrella- .

나아가, 최고급 원단, 방수기능, UV차단 등으로 내구성이 탁월하여 7~8년 이상 사용 가능하며, 특히 일광견뢰도(Light Fastness)가 3등급 이상이고, 내수압(water column)이 3,000mm 이상을 유지하여 방수특성, 초발수성 및 내변색성과 내오염성, 방염성이 뛰어나 안전하고 수명이 긴 장점이 있다.In addition, it can be used for 7 ~ 8 years with excellent durability due to its finest fabrics, waterproof function and UV shielding. In particular, it has a light fastness of more than grade 3 and a water column of more than 3,000 mm Waterproof property, super water repellency, discoloration resistance, stain resistance and flame retardancy, and is safe and has a long life span.

여기에서, 일광견뢰도란 자외선에 의해 퇴색되지 않고 견디는 성질을 말하며, 직물의 경우 자외선안정제를 처리할 경우 보통 일광견뢰도가 5등급, 잘 나오면 4등급 정도이다.Here, sunlight fastness refers to the property of not being discolored by ultraviolet rays. In the case of fabrics, when the ultraviolet light stabilizer is treated, the light fastness is usually 5, and when it comes out well, it is 4.

또한, 내수압은 물의 압력을 견디는 정도를 의미하며, 통상은 방수성 기준으로 삼는데, 내수압 1500mm는 원단 1mm당 1,500ℓ의 물을 부었을 때 견디는 정도를 나타내는 것을 말하며, 가랑비는 내수압 500mm, 보통비는 1000mm, 폭우는 1,500mm 정도에 해당하는 것으로 알려져 있다.The water pressure refers to the degree of resistance to water pressure. Normally, water resistance is used as the standard. The water pressure 1500mm refers to the degree of resistance to water when 1,500 liters of water per 1mm of the fabric is used. The water pressure is 500mm, 1000mm, and rainfall is about 1,500mm.

때문에, 본 발명의 경우 일광견뢰도가 3등급에 달하고, 내수압도 3000mm에 달해 매우 우수한 특성을 가짐을 알 수 있다.Therefore, in the case of the present invention, the fastness to light of daylight reaches grade 3, and the water pressure reaches 3000 mm, which is an excellent property.

보다 구체적으로, 도 1 내지 도 3의 예시와 같이, 본 발명에 따른 대형 파라솔은 지면에 고정되는 베이스블럭(100)과, 상기 베이스블럭(100)에 360°회전가능하게 일단이 끼워져 고정되고 타단은 수직연장 후 절곡된 파이프 형상의 기둥(110)과, 상기 기둥(110)의 타단에 고정된 힌지(170)와, 일단은 상기 힌지(170)에 고정되어 회전가능하게 설치지고 타단은 절곡 연장된 지지대(120)와, 상기 지지대(120)의 단부에 고정되어 우산처럼 접거나 펼수 있는 차양막(130)과, 상기 기둥(110)에 고정되고 래치(latch)를 갖춘 수동윈치(140)와, 일단은 상기 수동원치(140)에 감겨 고정되고 타단은 지지대(120)를 따라 배열된 후 차양막(130)에 고정되어 수동윈치(140)의 감김 방향에 따라 차양막(130)을 접거나 펼치는 와이어(150)와, 상기 기둥(110)에 설치되어 상기 지지대(120)가 더 이상 회전하지 않도록 고정하는 고정핀(160)을 포함한다.1 to 3, a large parasol according to the present invention includes a base block 100 fixed to the ground, a base block 100 fixed to the base block 100 so as to be rotatable by 360, And a hinge 170 fixed to the other end of the column 110. The other end of the hinge 170 is fixed to the hinge 170 so as to be rotatable and the other end is bent A manual winch 140 fixed to the column 110 and equipped with a latch and a wing 140 fixed to the column 110. The manual winch 140 is fixed to the end of the support 120 and can be folded or unfolded like an umbrella, The other end of the wire is fixed to the manual jig 140 and the other end of the wire is arranged along the support 120 and is fixed to the javelin 130 to fold or expand the jellyfish 130 along the winding direction of the manual winch 140 150 installed on the column 110 so that the support table 120 is rotated (Not shown).

이때, 상기 기둥(110)의 수직한 부분 상측에는 공지된 드럼식 브레이크를 갖춘 가이드롤(180)이 더 설치되어 상기 와이어(150)가 경유되게 함으로써 와이어(150)를 감거나 당길 때 원활하게 움직일 수 있도록 안내한다.At this time, a guide roll 180 having a known drum type brake is further provided on a vertical portion of the column 110 to allow the wire 150 to pass therethrough to move smoothly when the wire 150 is wound or pulled .

특히, 가이드롤(180)에 일체로 구성된 드럼식 브레이크는 와이어(150)가 불측의 이유로 절손되었을 때 차양막(130)이 순간적으로 접어지면서 그 하부에 있던 사용자나 혹은 그 주변을 지나던 행인에게 안전사고를 일으키기 않도록 브레이킹하기 때문에 안전성을 더욱 높일 수 있다.Particularly, the drum type brake integrated with the guide roll 180 causes a safety accident when the wire 150 is broken due to an unspecified cause, and the winging film 130 is momentarily folded and the user who is under the wing film 130 or a passer- Since it is braked not to cause it, safety can be further enhanced.

한편, 본 발명에 따른 대형 파라솔에 사용되는 차양막(130)은 폴리에스터로 직조한 원단에 폴리테트라플로오르에틸렌(PTFE)을 코팅액으로 하여 스프레이 코팅처리한 것을 기본형으로 한다.Meanwhile, the shading film 130 used in the large parasol according to the present invention is formed by spray-coating a fabric made of polyester with polytetrafluoroethylene (PTFE) as a coating liquid.

보통, 파라솔은 나일론을 원단으로 사용하지만, 본 발명에서는 폴리에스터 원사로 직조한 것으로 원단으로 사용한다.Usually, the parasol uses nylon as the fabric, but in the present invention, the fabric is woven with polyester yarn and used as a fabric.

이것은 폴리에스터 원사의 경우 나일론에 비해 비중이 크기 때문에 단위 면적당 강도가 높고, 얇게 제작할 수 있을 뿐만 아니라, 나일론 대비 일광 견뢰도도 훨씬 우수하기 때문이다.This is because polyester yarn has a larger specific gravity than nylon, and thus has a high strength per unit area, can be made thin, and has a much better daylight fastness than nylon.

그리고, 상기 코팅액을 구성하는 폴리테트라플로오르에틸렌(PTFE)은 불소수지의 하나로서 절연안정성과 비점착성 및 낮은 마찰계수로 인해 발수특성과 방수특성이 우수한 물질이다. Polytetrafluoroethylene (PTFE) constituting the coating liquid is one of the fluororesin materials and is excellent in water repellency and waterproof properties due to insulation stability, non-tackiness, and low coefficient of friction.

특히, 코팅면이 매끄럽고 스프레이 코팅 후 코팅층에 대한 내수압 테스트시 10,000mm의 내수압 특성이 있는 것으로 알려져 있으며, 일광견뢰도의 등급을 강화시키는 특성도 있는 것으로 알려져 있다.Particularly, it is known that the coated surface is smooth and has a water pressure resistance of 10,000 mm in the water pressure test for the coating layer after spray coating, and it is known that there is also a property to enhance the degree of light fastness of the light.

때문에, 본 발명에서는 폴리테트라플로오르에틸렌(PTFE)의 이러한 특성을 이용하여 방오성(오염방지성)까지 확보하도록 구성된 것이다.Therefore, the present invention is configured to secure antifouling property (contamination preventing property) by using such a property of polytetrafluoroethylene (PTFE).

이때, 상기 코팅액에는 액상 멜라민수지 5중량%와, 붕규산유리 3.5중량%가 더 첨가될 수 있다.At this time, 5 wt% of liquid melamine resin and 3.5 wt% of borosilicate glass may be added to the coating solution.

이 경우, 상기 액상 멜라민수지는 접착력을 극대화시켜 코팅층의 표면 박리를 강력하게 억제하며, 상기 붕규산유리는 규산분 80중량%와 나머지 붕산분 및 기타 불가피한 성분들로 이루어진 것으로 낮은 열팽창율을 가지므로 열팽창과 수축이 적어 차양막(130)이 접었다 펼쳐지는 것이 반복되더라도 코팅층에서 크랙 발생을 억제하여 내구성을 높이면서 내열충격성과 화학적내구성을 높이게 된다.In this case, the liquid melamine resin maximizes the adhesive force and strongly suppresses the surface peeling of the coating layer. The borosilicate glass is composed of 80 wt% of silicate powder, remaining boric acid powder and other unavoidable components, and has a low coefficient of thermal expansion, Even if the shading film 130 is folded and unfolded repeatedly, the occurrence of cracks in the coating layer is suppressed, thereby increasing the durability and improving the thermal shock resistance and chemical durability.

본 발명은 이에 그치지 않고 특성을 더욱 강화시키기 위해 차양막(130)을 개량형으로 구성할 수도 있다.The present invention can be applied to an improved type of shielding film 130 to further enhance the characteristics.

본 발명에 따른 개량형은 폴리에스터 80중량%와, 폴리비닐알콜 20중량%로 혼합된 혼합수지로부터 얻어진 원사로 직조된 원단을 사용한다.The modified type according to the present invention uses a yarn-woven fabric obtained from a mixed resin mixed with 80% by weight of polyester and 20% by weight of polyvinyl alcohol.

이때, 폴리비닐알콜은 질긴 특성이 있어 접착성 있는 방수막 형성에 기여하여 원단 자체적으로 방수특성을 더욱 강화시키게 된다.At this time, the polyvinyl alcohol has a tough characteristic and contributes to the formation of an adhesive waterproof film, thereby further enhancing the waterproof property of the fabric itself.

그리고, 본 발명에 따른 개량형은 폴리에스터와 폴리비닐알콜이 혼방된 원단을 함침액에 함침시켜 건조한다.Further, in the modified type according to the present invention, the impregnated liquid is impregnated with a fabric blended with polyester and polyvinyl alcohol to dry.

여기에서, 상기 함침액은 원단이 발수성, 일광견뢰도, 방오성 및 방염성을 확보하도록 하기 위한 것이다.Here, the impregnating liquid is intended to ensure that the fabric has water repellency, light fastness, antifouling property and flame retardancy.

이를 위해, 상기 함침액은 수산화알루미늄 1.5중량%와, 올레아미드(Oleamide) 5.5중량%와, HDFS(Heptadeca-fluoro-1,1,2,2-tetra-hydrodecyltrichloro-silane) 2.5중량%와, 이소프로필에테르 8중량%와, 디아릴프탈레이트 3.5중량%와, 멜라민 포스페이트 5.5중량%와, 시아노아크릴레이트 2.5중량%와, 에테닐 아세테이트 2.5중량%와, 펜타에리스리톨 5.5중량%와, 트랜스-1,2-에틸렌 디카르복실산 2.5중량% 및 나머지 폴리에스터 수지로 이루어진다.To this end, the impregnating solution was prepared by mixing 1.5 wt% of aluminum hydroxide, 5.5 wt% of oleamide, 2.5 wt% of heptadeca-fluoro-1,1,2,2-tetra-hydrodecyltrichloro-silane (HDFS) A mixture of 8 wt% of propyl ether, 3.5 wt% of diaryl phthalate, 5.5 wt% of melamine phosphate, 2.5 wt% of cyanoacrylate, 2.5 wt% of ethenyl acetate, 5.5 wt% of pentaerythritol, 2.5% by weight of 2-ethylenedicarboxylic acid and the rest of the polyester resin.

이때, 상기 수산화알루미늄은 난연 특성을 강화시키기 위해 첨가된다.At this time, the aluminum hydroxide is added to enhance the flame retarding property.

또한, 상기 올레아미드(Oleamide)는 슬립성을 강화시켜 함침시 함침액의 원활한 흐름과 분산, 함침성을 유도하기 위해 첨가된다.In addition, the oleamide is added to enhance the slip property to induce smooth flow, dispersion and impregnation of the impregnation solution at the time of impregnation.

그리고, 상기 HDFS는 트리클로로실란 계열로서 실란 그룹이 포함된 알킬기 혹은 불소가 치환된 알킬기 물질에 의해 소수성을 강화시키게 되며, 강고한 함침성을 유지시키기 위해 첨가된다.The HDFS enhances hydrophobicity by an alkyl group containing a silane group or an alkyl group material substituted by a fluorine as a trichlorosilane series, and is added to maintain a strong impregnation property.

아울러, 상기 이소프로필에테르(Iso-PropylEther)는 가교기능을 통해 경화피막을 형성함으로써 내구성과 내오염성을 증대시키기 위해 첨가된다.In addition, the isopropyl ether (Iso-PropylEther) is added to increase durability and stain resistance by forming a cured coating through a crosslinking function.

뿐만 아니라, 상기 히드록시프롤린(hydroxyproline)은 젤라틴 가수 분해물에서 라이네케염으로서 원단의 표면 유연성을 더욱 강화시키기 위해 첨가된다.In addition, the hydroxyproline is added to further enhance the surface flexibility of the fabric as a ligne salt in the gelatin hydrolyzate.

또한, 상기 디아릴프탈레이트는 접착성과 인성을 개선하여 함침액과 원단 사이의 계면에서 부착안정성을 강화시키기 위해 첨가된다.The diaryl phthalate is added to improve adhesion and toughness so as to enhance adhesion stability at the interface between the impregnation liquid and the fabric.

아울러, 멜라민 포스페이트는 질소가 함유되어 있어 난연상승 기능을 갖는 무독성으로서, 특히 할로겐이 함유되어 있지 않아 독성이 없어 인체 유해성을 배제시킨다.In addition, melamine phosphate is a non-toxic material having a flame-retarding function because it contains nitrogen, and in particular, it does not contain halogen and thus is not toxic, thereby eliminating harmfulness to the human body.

그리고, 상기 시아노아크릴레이트(cyanoacrylate)는 열팽창을 억제하고 함침액의 접착고정력을 극대화시켜 계면 분리를 억제하기 위해 첨가된다.The cyanoacrylate is added to suppress thermal expansion and to maximize the adhesive force of the impregnation liquid to suppress interfacial separation.

뿐만 아니라, 상기 에테닐 아세테이트(CH2CHCOOCH3)는 수지의 스티프니스(stiffness)와 인장강도 조절용으로 사용된다.In addition, ethenyl acetate (CH 2 CHCOOCH 3 ) is used for controlling the stiffness and tensile strength of the resin.

또한, 상기 펜타에리스리톨은 합성고무와 플라스틱의 중간 특성을 가진 물질로서 연소시 화염방지와 한계산소지수의 상승을 유도하여 발화저항성을 크게 하기 위해 첨가된다.In addition, the pentaerythritol is a material having intermediate characteristics between synthetic rubber and plastic, which is added in order to prevent flame and increase the critical oxygen index during combustion and increase ignition resistance.

아울러, 상기 트랜스-1,2-에틸렌 디카르복실산(C4H4O4)은 수지의 입자 표면에서 입자간 반발력을 제공하여 입자간 엉김현상을 방지하고 분산안정성을 부여하기 위해 첨가된다.In addition, the trans-1,2-ethylene dicarboxylic acid (C 4 H 4 O 4 ) is added to provide intergranular repulsive force at the particle surface of the resin to prevent entanglement and provide dispersion stability.

마지막으로, 상기 폴리에스터 수지는 원단과의 교합성을 절대적으로 증대시키기 위한 베이스 수지이다.Finally, the polyester resin is a base resin for absolutely increasing the intertwining with the fabric.

이와 같은 함침액에 함침된 후 건조된 원단은 그 표면(양면)에 코팅액이 코팅되어 일광견뢰도 및 방오성을 더욱 강화시키게 된다.The impregnated and impregnated fabric is coated with a coating solution on its surface (both sides) to further enhance the light fastness and antifouling property.

이 경우, 상기 코팅액은 액상 멜라민수지 5중량%와, 붕규산유리 3.5중량% 및 나머지 폴리테트라플로오르에틸렌(PTFE)으로 이루어진다.In this case, the coating liquid is composed of 5% by weight of liquid melamine resin, 3.5% by weight of borosilicate glass, and the remaining polytetrafluoroethylene (PTFE).

이에 더하여, 상기 코팅액에는 코팅액 100중량부에 대해 호모살리에이트 10.5중량부와, 메타인산염 4.5중량부 및 2-페닐이미다졸 5.5중량부가 더 첨가될 수 있다.In addition, 10.5 parts by weight of homosalate, 4.5 parts by weight of metaphosphate and 5.5 parts by weight of 2-phenylimidazole may be further added to 100 parts by weight of the coating liquid.

이때, 상기 호모살리에이트는 원단 표면으로 조사된 자외선을 흡수하여 분해함으로 인해 일광견뢰도를 증대시키는 효능을 유지한다.At this time, the homosalate absorbs and decomposes ultraviolet light irradiated to the surface of the fabric, thereby maintaining the efficacy of increasing the fastness of daylight.

또한, 상기 메타인산염은 원단 표면에서의 산화방지 기능을 강화시키기 위해 첨가되고, 상기 2-페닐이미다졸은 건조시 열수축률을 적게 하여 코팅액의 열안정성을 강화시킬 뿐만 아니라 코팅층의 부착력을 증대시키기 위해 첨가된다.In addition, the metaphosphate is added to enhance the antioxidant function on the surface of the fabric, and the 2-phenylimidazole reduces the heat shrinkage rate during drying to enhance the thermal stability of the coating solution and increase the adhesion of the coating layer Lt; / RTI >
