콘크리트 구조물의 수분에 의한 부식이나 파손 등을 방지하기 위해서는 콘크리트 구조물 표면에 방수 또는 방식 처리를 하는 것이 요구된다. 이러한 방수 처리는 일반적으로 방수용 수지를 콘크리트 구조물의 표면에 도포함으로서 이루어진다.In order to prevent corrosion or damage caused by moisture of concrete structure, it is required to waterproof or treat the surface of concrete structure. Such waterproofing treatment is generally performed by applying a waterproof resin to the surface of a concrete structure.
종래 일반적인 콘크리트 구조물 표면의 방수 공법은, 등록특허 10-1215403호 등에 개시된 바와 같이, 방수하고자 하는 구조물의 표면에 묻은 오염물을 제거하고 평탄화하는 전처리 단계와, 상기 전처리된 표면에 프라이머를 코팅하여 프라이머층을 형성하는 단계 및 상기 프라이머층 상에 에폭시 코팅제를 도포하는 단계를 포함하여 이루어진다.A conventional waterproofing method for a concrete structure surface includes a pretreatment step of removing contaminants on the surface of a waterproofing structure and planarizing the surface of the waterproofing structure as disclosed in Japanese Patent Application No. 10-1215403 and the like, And applying an epoxy coating agent on the primer layer.
이러한 에폭시 수지 조성물은, 얻어지는 경화물의 기계적 성질, 내식성, 밀착성 등이 뛰어나기 때문에 도료, 접착제, 적층판, 전자 부품 용도 등의 각 분야에서 널리 사용되고 있으나, 대부분 유기 용제에 희석한 조성물로 사용되는 실정이므로, 최근 환경 문제가 부각됨에 따라 수성화가 기대되고 있다. Such epoxy resin compositions are widely used in various fields such as paints, adhesives, laminated plates, and electronic parts because they have excellent mechanical properties, corrosion resistance and adhesiveness, but they are mostly used as compositions diluted with organic solvents Recently, as the environmental problems become more prominent, water-based improvement is expected.
여기서, 수성 에폭시 수지는, 예를 들면, 계면활성제를 사용하여 호모 믹서로 고속 교반하여 제조되는 에폭시 수지 에멀젼이 널리 알려져 있는 상태이지만, 계면활성제의 영향으로 내수성과 접착성 등의 물성이 저하되는 등의 문제점이 있다. Here, the aqueous epoxy resin is an epoxy resin emulsion prepared by, for example, using a surfactant and stirring at a high speed with a homomixer. However, since the properties such as water resistance and adhesiveness are lowered due to the influence of the surfactant .
반면, 계면활성제를 함유하지 않는 수성 에폭시 수지는, 비스디페놀의 디글리시딜에테르, 비스디페놀 및 폴리옥시알킬렌글리콜의 디글리시딜에테르를 반응시킨 것과 비스디페놀의 디글리시딜에테르, 비시드페놀, 폴리옥시알킬렌글리콜의 디글리시딜에테르 및 디이소시아네이트를 반응시킨 것 등이 있다. 또한, 2관능 이상의 에폭시 수지, 다가 페놀 및 지방족 폴리올로 이루어지는 축합 생성물과 2관능 이상의 에폭시 주지, 모노 및 폴리이소시아네이트로 이루어지는 축합 생성물 등이 있다.On the other hand, the aqueous epoxy resin containing no surfactant is obtained by reacting diglycidyl ether of bisdiphenol, bisdiphenol and diglycidyl ether of polyoxyalkylene glycol with diglycidyl of bisdiphenol Ether, uncapped phenol, diglycidyl ether of polyoxyalkylene glycol, and diisocyanate. Further, condensation products of bifunctional or higher-functional epoxy resins, polyhydric phenols and aliphatic polyols, and condensation products of bifunctional or higher epoxy resins, mono- and polyisocyanates, and the like are available.

The curing agent was prepared by mixing 100 parts by weight of an emulsion prepared by mixing ethoxylated bisphenol A dimethacrylate and dicyclopentyloxyethyl methacrylate in a volume ratio of 8: 2 to 2 parts by weight of 2-phenoxy 70 to 90 parts by weight of ethylmethacrylate, 60 to 80 parts by weight of aminomethylpropanol, 50 to 70 parts by weight of dimethylbutanoleic acid, 40 to 60 parts by weight of 3-methoxybutyl acetate, 7 to 10 parts by weight of pigment, 5 to 8 parts by weight of a defoaming agent is added.
또한, 상기 수성 에폭시 코팅제는, 2액형의 주제와 경화제가 5:2의 부피비로 혼합되어 완결 또는 생성된다.In addition, the aqueous epoxy coating agent is completed or produced by mixing two-component type of a base and a curing agent in a volume ratio of 5: 2.
상기 폴리(4-비닐피리딘)는, 수성 에폭시 코팅제 시공시 방수성과 내마모성을 제공하여 투수비와 흡수비를 낮추기 위한 것으로, 과산화물, 빛, 열 등에 의해 쉽게 중합을 일으키고 중합사슬 사이의 다리 걸침을 일으켜 혼합물의 결합 및 반응이 이루어지도록 한다.The poly (4-vinylpyridine) is intended to lower water permeability and absorption ratio by providing waterproof and abrasion resistance in the construction of an aqueous epoxy coating, and easily causes polymerization by peroxide, light, heat, etc., Allowing the binding and reaction of the mixture to take place.
상기 에틸렌-N-브로모말레이이미드코폴리머는, 상기 경화제와 혼합시 상용화제로 작용하는 반응형 수지로, 내구성, 내열성, 내화학성, 내마모성, 자외선안전성 등 물성이 뛰어나고, 햇빛 등의 날씨 및 기후에 견디는 성질인 내후성이 우수하며 외부 환경 변화에 의한 부식 등을 억제함과 동시에 구조물의 표면에 침투하여 일체화를 가능하게 하여 부착강도 및 인성을 개선하고 안료 등에 의한 착색성을 좋게 하는 기능을 제공한다.The ethylene-N-bromomaleimide copolymer is a reactive resin that acts as a compatibilizer when mixed with the curing agent, and is excellent in properties such as durability, heat resistance, chemical resistance, abrasion resistance, ultraviolet safety, It is excellent in weatherability, which is resistant to weathering, and is capable of inhibiting corrosion due to changes in the external environment and penetrating into the surface of the structure so as to be integrated, thereby improving the adhesion strength and toughness and improving the coloring property by the pigment and the like.
여기서, 상기 에틸렌-N-브로모말레이이미드코폴리머는, 상기 폴리(4-비닐피리딘) 100 중량부에 대하여 80~90 중량부가 첨가되는데, 80 중량부 보다 적게 첨가되면 구조물의 표면과의 부착강도가 저하되어 내마모성 및 내후성 등이 크게 저하되고, 90 중량부 보다 많이 첨가되면 빠른 시간에 경화가 이루어져 구조물의 표면 깊숙이 침투하지 못하게 되어 오히려 부착강도가 저하되고 내마모성 및 내후성 등이 크게 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다. The ethylene-N-bromomaleimide copolymer is added in an amount of 80 to 90 parts by weight based on 100 parts by weight of the poly (4-vinylpyridine). When less than 80 parts by weight of the copolymer is added, And when it is added in an amount of more than 90 parts by weight, curing takes place in a short period of time, so that it can not penetrate deeply into the surface of the structure, so that the adhesion strength is lowered and abrasion resistance and weather resistance are greatly deteriorated , And it is preferable to have such a limited weight portion as described above.
상기 폴리(4-하이드록시-3-니트로스타이렌)는, 상기 조성물들의 혼합물인 에폭시 코팅층의 표면이 코팅되도록 하는 기능을 제공한다. The poly (4-hydroxy-3-nitrostyrene) provides the function of coating the surface of the epoxy coating layer, which is a mixture of the above compositions.
여기서, 폴리(4-하이드록시-3-니트로스타이렌)는, 상기 폴리(4-비닐피리딘) 100 중량부에 대하여 70~80 중량부가 첨가되는데, 70 중량부 보다 적게 첨가되면 에폭시 코팅층의 코팅에 따른 피복 효과가 저하되고, 80 중량부 보다 많이 첨가되면 에폭시 코팅층의 건조시 코팅 입자들이 커지거나 혹은 엉기는 현상이 발생되어 에폭시 코팅층의 표면이 고르지 못하게 되어 내구성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.Herein, 70 to 80 parts by weight of poly (4-hydroxy-3-nitrostyrene) is added to 100 parts by weight of the poly (4-vinylpyridine). When less than 70 parts by weight is added, coating of the epoxy coating layer And if it is added in an amount of more than 80 parts by weight, the coating particles become large or coarse at the time of drying of the epoxy coating layer, resulting in unevenness of the surface of the epoxy coating layer, resulting in poor durability. It is preferable to have a limited weight portion.
한편, 상기 주제의 제조시, 상기와 같이 폴리(4-비닐피리딘)에 에틸렌-N-브로모말레이이미드코폴리머와 폴리(4-하이드록시-3-니트로스타이렌)가 소정의 중량비를 가지면서 혼합된 상태에서 교반 또는 반응온도를 130~150℃로 한정하는 것은, 교반온도가 130℃ 보다 낮으면 팽윤율이 저하되고, 교반온도가 150℃ 보다 높으면 과팽윤이 되는 문제점이 있으므로, 상기와 같은 한정된 범위의 교반온도가 유지되는 것이 바람직하다.On the other hand, in the production of the above-mentioned subject, when the ethylene-N-bromomaleimide copolymer and the poly (4-hydroxy-3-nitrostyrene) are mixed in the poly (4-vinylpyridine) When the stirring temperature or the stirring temperature or the reaction temperature is in the range of 130 to 150 ° C., the swelling rate is lowered when the stirring temperature is lower than 130 ° C. and the swelling is caused when the stirring temperature is higher than 150 ° C. Therefore, It is preferred that a limited range of agitation temperatures be maintained.
또한, 상기 주제의 제조시, 상기와 같이 폴리(4-비닐피리딘)에 에틸렌-N-브로모말레이이미드코폴리머와 폴리(4-하이드록시-3-니트로스타이렌)가 소정의 중량비를 가지면서 혼합된 상태에서 교반 또는 반응시간을 10~13시간으로 한정하는 것은, 교반시간이 10시간 보다 짧으면 팽윤이 잘 안되고, 교반시간이 13시간 보다 길면 고증점이 되는 문제점이 있으므로, 상기와 같은 한정된 범위의 교반시간이 유지되는 것이 바람직하다. Further, in the production of the above-mentioned subject, it is preferable that the poly (4-vinylpyridine) has an ethylene-N-bromomaleimide copolymer and poly (4-hydroxy-3-nitrostyrene) The stirring or the reaction time in the mixed state is limited to 10 to 13 hours because if the stirring time is shorter than 10 hours, the swelling is poor and when the stirring time is longer than 13 hours, It is preferred that the agitation time be maintained.
상기 에톡시레이티드비스페놀A디메타아크릴레이트와 디사이클로펜틸옥시에틸메타아크릴레이트가 8:2의 부피비로 혼합된 에멀전은, 에폭시 코팅제의 방수막 시공시 부착력 증대와 보관시 층분리 현상을 방지하여 방수성을 제공하는 혼합물이다. The emulsion in which the ethoxylated bisphenol A dimethacrylate and dicyclopentyloxyethyl methacrylate are mixed in a volume ratio of 8: 2 prevents the layer separation during the deposition of the waterproof film of the epoxy coating agent It is a mixture that provides water resistance.
여기서, 상기 에멀전은 에톡시레이티드비스페놀A디메타아크릴레이트와 디사이클로펜틸옥시에틸메타아크릴레이트가 8:2의 부피비로 혼합되는데, 상기 에톡시레이티드비스페놀A디메타아크릴레이트가 8 부피비를 초과하는 경우에는 상기 혼합물들의 반응속도가 너무 빨라지게 되어 교반성 및 시공성이 저하되고, 8 부피비를 미만하는 경우에는 상기 혼합물들의 반응속도가 너무 느려지게 되어 작업 시간이 증가하게 되는 문제점이 있으며, 상기 디사이클로펜틸옥시에틸메타아크릴레이트가 2 부피비를 초과하는 경우에는 점성이 너무 커지게 되어 상기 혼합물들과의 교반 작업이 불편해지고, 2 부피비를 미만하는 경우에는 혼합물의 저장 안정성이 저조하게 되어 도막의 접착 강도가 저하되는 문제점이 있다. Wherein the emulsion is prepared by mixing ethoxylated bisphenol A dimethacrylate and dicyclopentyloxyethyl methacrylate in a volume ratio of 8: 2, wherein the ethoxylated bisphenol A dimethacrylate is in an amount greater than 8 parts by volume The reaction speed of the mixture becomes too fast to degrade the crosslinkability and the workability. When the ratio is less than 8, the reaction speed of the mixture becomes too slow, which increases the working time. When the cyclopentyloxyethylmethacrylate exceeds the volume ratio of 2, the viscosity becomes too large and the stirring operation with the mixtures becomes inconvenient. When the volume ratio is less than 2, the storage stability of the mixture becomes poor, There is a problem that the strength is lowered.
이에, 상기 에멀전은, 상기와 같은 한정된 부피비를 가지는 것을 통하여 향상된 교반성, 안정성, 시공성 및 작업성 등의 효과가 제공되도록 하는 것이 바람직하다.Thus, it is desirable that the emulsion has such a limited volume ratio as to provide improved effects such as agility, stability, workability, and workability.
상기 2-페녹시에틸메타아크릴레이트는, 상기 에멀전에 혼합되는 혼합물들이 혼합되도록 하는 점도조절제 또는 결합제이다.The 2-phenoxyethylmethacrylate is a viscosity modifier or binder which allows the mixtures to be mixed with the emulsion to be mixed.
여기서, 상기 2-페녹시에틸메타아크릴레이트는, 상기 에멀전 100 중량부에 대하여 70~90 중량부가 첨가되는데, 70 중량부 보다 적게 첨가되면 결합력이 발휘되지 못하여 전반적인 방수성이 저하되고, 90 중량부 보다 많이 첨가되면 강한 결합력으로 인하여 점도가 증가되어 오히려 교반 혼합이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.The amount of the 2-phenoxyethylmethacrylate added is 70 to 90 parts by weight based on 100 parts by weight of the emulsion. If less than 70 parts by weight of the emulsion is added, If a large amount is added, there is a problem that the viscosity is increased due to the strong binding force and the stirring mixing is lowered. Therefore, it is preferable to have the limited weight portion as described above.
상기 아미노메틸프로파놀은, 상기 에멀전에 혼합되는 혼합물들이 소정의 경도를 가지도록 하여 내구성, 색상 보유성, 백아화저항성 및 내스크래치성 등의 기능을 제공한다.The aminomethylpropanol provides a function such as durability, color retention, whitening resistance and scratch resistance by allowing the mixtures to be mixed with the emulsion to have a predetermined hardness.
여기서, 상기 아미노메틸프로파놀은, 상기 에멀전 100 중량부에 대하여 60~80 중량부가 첨가되는데, 60 중량부 보다 적게 첨가되면 에폭시 코팅층의 경도가 저하되어 내구성 등이 저하되고, 80 중량부 보다 많이 첨가되면 에폭시 코팅층의 경도가 너무 강하게 되어 구조물의 표면으로부터 들뜸 현상에 따른 부착 강도가 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.When the amount of the aminomethylpropanol is less than 60 parts by weight, the hardness of the epoxy coating layer is lowered and the durability and the like are lowered. When the amount of the aminomethylpropanol is more than 80 parts by weight There is a problem that the hardness of the epoxy coating layer becomes too strong and the adhesion strength due to the lifting phenomenon is lowered from the surface of the structure. Therefore, it is preferable that the epoxy coating layer has a limited weight as described above.
상기 다이메틸뷰타노익에시드는, 상기 경화제를 생성하는 혼합물들의 접착 강도 향상 기능을 제공한다.Said dimethyl butanoidside provides the adhesive strength enhancing function of the mixtures that produce said curing agent.
여기서, 상기 다이메틸뷰타노익에시드는, 상기 에멀전 100 중량부에 대하여 50~70 중량부가 첨가되는데, 50 중량부 보다 적게 첨가되면 상기 혼합물들의 반응속도가 너무 느려지게 되어 작업시간이 증가하게 되고, 70 중량부 보다 많이 첨가되면 상기 혼합물들의 반응속도가 너무 빨라지게 되어 작업성이 오히려 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.In this case, 50 to 70 parts by weight of seed is added to 100 parts by weight of the emulsion. If less than 50 parts by weight is added, the reaction speed of the mixture becomes too slow, If it is added in an amount more than the weight part, the reaction rate of the mixture becomes too high, and the workability is rather lowered. Therefore, it is preferable to have the limited weight part as described above.
상기 3-메톡시뷰틸아세테이트는, 상기 주제와 경화제가 혼합되는 에폭시 코팅제의 기계적 강도를 향상시키는 기능을 제공한다.The 3-methoxybutylacetate provides the function of improving the mechanical strength of the epoxy coating agent in which the subject and the curing agent are mixed.
여기서, 상기 3-메톡시뷰틸아세테이트는, 상기 에멀전 100 중량부에 대하여 40~60 중량부가 첨가되는데, 40 중량부 보다 적게 첨가되면 상기 에폭시 코팅제의 기계적 강도 즉, 내구성이 저하되어 외부의 충격에 대하여 쉽게 파손 또는 박리되고, 60 중량부 보다 많이 첨가되면 상기 에폭시 코팅제의 기계적 강도가 너무 증가하게 되어 외부의 충격을 탄성적으로 흡수하는 기능이 저하되어 오히려 내구성이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.When 40 parts by weight or less of the 3-methoxybutyl acetate is added to 100 parts by weight of the emulsion, the mechanical strength or durability of the epoxy coating is lowered, If the epoxy coating agent is added in an amount of more than 60 parts by weight, the mechanical strength of the epoxy coating agent is excessively increased, so that the function of elastically absorbing the external impact is lowered and the durability is lowered. It is preferable to have a weight part.
상기 안료는, 코팅층의 색상 기능을 제공한다.The pigment provides the color function of the coating layer.
여기서, 안료는, 상기 에멀전 100 중량부에 대하여 7~10 중량부가 첨가되는데, 상기 중량부를 가지지 않는 경우에는 코팅층 색상의 심미감이 저하되는 문제점이 있으므로, 상기와 같은 한정된 중량부를 가지는 것이 바람직하다.Here, the pigment is added in an amount of 7 to 10 parts by weight based on 100 parts by weight of the emulsion. When the pigment is not used, the color of the coating layer may deteriorate.
상기 소포제는, 상기 주제와 경화제의 조성물들의 교반시 발생되는 거품을 억제하여 교반성이 향상되도록 한다.The antifoaming agent suppresses the foaming that occurs during stirring of the composition of the subject and the curing agent, thereby improving the crosslinkability.
여기서, 상기 소포제는, 상기 에멀전 100 중량부에 대하여, 5~8 중량부가 혼합되는데, 상기 중량부를 초과하는 경우에는 상기 조성물들의 반응이 억제되고, 상기 중량부를 미만하는 경우에는 거품의 억제 기능이 저하되어 결국 교반 효율이 저하되는 문제점이 있으므로, 상기와 같은 한정된 범위의 중량부를 가지는 것이 바람직하다.When the amount of the defoaming agent exceeds 100 parts by weight based on 100 parts by weight of the emulsion, the reaction of the compositions is inhibited. When the amount of the defoaming agent is less than the weight of the emulsion, And thus the stirring efficiency is deteriorated.

When the base is more than 5 parts by volume, If the amount of the curing agent is more than 2 parts by volume, the curing time of the coating layer is accelerated and the workability such as the flattening operation is deteriorated When the volume ratio is less than 2, the curing of the coating layer takes too much time.
