Description
본 발명은 유성잉크젯 잉크의 인쇄성 향상과 저온 내크랙성이 우수한 수성 실사표면코팅제 개발에 관한 것이다.The present invention relates to the development of an aqueous photo-realistic surface coating agent excellent in printability improvement and low temperature crack resistance of an oil-based inkjet ink.
'광고용 소재의 저밀도 폴리에틸렌 배너 및 그의 제조방법'(등록번호:10-0452272)에는 PET 부직포 원단의 양면에 LDPE를 압사출하는 방식이다. 이 방식은 이번 특허의 코팅방식에 비해 설치비나 공정상 어려움이 있고, LDPE의 경우 실제 내용제성이 우수하여 용제형 잉크젯 잉크 인쇄에는 맞지 않는다.'Low density polyethylene banner of advertising material and its manufacturing method' (Registration No.:10-0452272) is a method of extruding LDPE on both sides of the PET nonwoven fabric. This method has difficulty in installation cost or process compared to the coating method of this patent, and LDPE is not suitable for solvent type inkjet ink printing due to its excellent solvent resistance.
'잉크젯 실사용 방염원단'(등록번호 :10-0743107)의 경우 수지 종류에 있어서 본 특허에서 하고자 하는 디스퍼젼 방식의 수지에 대한 내용에 빠져 있고, 아크릴과 우레탄을 각각 또는 혼합하여 사용하였을 경우 상용성 문제 및 MILD 용제형 잉크젯 잉크에서는 잉크 건조성에 문제가 발생한다.In the case of 'Inkjet practical flame retardant fabric' (Registration No .: 10-0743107), the resin type is missing from the dispersion type resin to be patented in this patent, and is commercially available when acryl and urethane are used separately or mixed. Sex and MILD solvent type inkjet inks have problems with ink drying.
일반적으로 PVC 기재를 사용할 경우에는 유성 TYPE의 잉크젯 잉크를 사용하면 유기 용제에 의한 기재 용해에 의해 접착이 이루어 진다. 하지만 PVC 사용에 따른 환경적인 문제가 발생하게 된다. 그로 인해 PVC를 대체하고자 PET, PP, TPO 등 친환경적인 제품들을 이용한 실사 기재가 개발되고 있는 상황이다. 하지만 이들 기재들은 내용제성이 우수하여 강용제 TYPE의 잉크젯 잉크로 인쇄했을 때에도 용제에 의한 기재의 용해가 이루어지지 않아 접착이 불량한 결과를 보인다. 특히 MILD용제 TYPE의 잉크젯 잉크를 사용할 경우에는 잉크의 건조성 및 인쇄성이 불량한 결과를 보인다. 상기한 문제를 개선하고자 한다.In general, in case of using a PVC substrate, when an oil type inkjet ink is used, adhesion is performed by dissolving the substrate by an organic solvent. However, environmental problems are caused by the use of PVC. As a result, due diligence is being developed using eco-friendly products such as PET, PP, and TPO to replace PVC. However, since these substrates have excellent solvent resistance, even when printed with inkjet ink of a strong solvent type, the substrate is not dissolved by a solvent and thus shows poor adhesion. In particular, when the MILD solvent type inkjet ink is used, the dryness and printability of the ink are poor. It is intended to improve the above problem.
또한 유성 TYPE의 실사표면코팅제의 경우 TVOC 문제가 발생할 수 있어, 이 문제 또한 해결해야하는 과제이다. In addition, in the case of the oil-based type photoreal surface coating agent, a TVOC problem may occur, which is also a problem to be solved.
본 발명에서 개발하고자 하는 표면코팅제는 일반 PVC 기재에도 사용이 가능하지만 특히 PVC를 대체하고자 사용되고 있는 PET, PP, TPO 등에 적용하는 것을 주 목적으로 하고 있다. 잉크 수용층 개발에 있어서 유성 TYPE의 수지를 사용하지 않고 친환경적인 수성 TYPE의 수지를 사용함으로서 환경적으로 문제가 되는 VOC 문제를 해결할 수 있다. 수성 TYPE의 수지는 일반적으로 아크릴에멀젼, PUD(폴리우레탄디스퍼젼)과 AUD(아크릴우레탄디스퍼젼)를 말한다. 그리고 그 수지에 각종 필러, 첨가제등을 혼합하게 되면 VOC 문제를 해결할 수 있다. 수지와 첨가제의 배합을 통해 인쇄성, 건조성 및 저온 내크랙성 등이 우수한 표면코팅제를 개발한다.The surface coating agent to be developed in the present invention can be used for general PVC substrates, but the main purpose is to apply to PET, PP, TPO, etc., which are used to replace PVC in particular. In developing the ink receiving layer, it is possible to solve the VOC problem that is environmentally problematic by using an environmentally friendly aqueous type resin instead of using an oil type type resin. Aqueous TYPE resin generally refers to acrylic emulsion, PUD (polyurethane dispersion) and AUD (acrylurethane dispersion). In addition, mixing various fillers and additives with the resin may solve the VOC problem. Through the combination of resin and additives, we develop a surface coating agent with excellent printability, dryness and low temperature crack resistance.
현재 인쇄타포린의 경우 주를 이루는 것이 PVC 기재이다. 하지만 친환경적인 문제에 있어서 PVC는 자유롭지 못하다. 이를 대체하기 위해 PP, PET, TPO 등이 사용되고 있다. 하지만 이들은 유성 잉크젯 잉크를 사용할 경우 PVC 타포린과는 다르게 용제를 흡수하지 못하기 때문에 인쇄성, 건조성 면에서 불량함을 나타낸다. 따라서 PP, PET, TPO 등 친환경 타포린을 사용하기 위해서는 본 발명의 표면코팅제가 반드시 필요하다. 현재 유성 제품을 이용한 표면코팅제가 생산되어지고 있는데 VOC 문제가 발생하여 친환경적이라 할 수 없다. 따라서 수성 실사 표면코팅제를 사용함으로서 VOC 문제를 해결하고 작업 중 안정성도 우수하며 인쇄성 및 건조성을 향상시킬 수 있는 효과가 있다. Currently, printed tarpaulin is mainly PVC-based. However, PVC is not free when it comes to environmental issues. To replace this, PP, PET, TPO, etc. are used. However, they show poor printability and dryness because oil inkjet inks do not absorb solvents unlike PVC tarpaulin. Therefore, in order to use environmentally friendly tarpaulin, such as PP, PET, TPO, the surface coating agent of the present invention is necessary. Currently, surface coatings using oil-based products are being produced, which is not environmentally friendly due to VOC problems. Therefore, the use of an aqueous photo-realistic surface coating agent has the effect of solving the VOC problem, excellent stability during operation, and improve the printability and drying properties.

<인쇄성 측정방법><Measurement of printability>
상기 코팅된 기재에 유성 잉크젯 프린터를 이용해 그림을 인쇄한 후에 비교예와 상대비교 확인한다.After printing a picture on the coated substrate using an oil inkjet printer, the relative comparison with the comparative example is confirmed.
상대적으로 비교했을 때 PUD의 경우 저온 내크랙성이 AUD에 비해 양호하나 잉크 건조성 및 인쇄성이 불량하고, AUD의 경우는 인쇄성 및 잉크 건조성 면에서 우수하나 저온 내크랙성 면에서 불량함을 보인다.In comparison, PUD has better low temperature crack resistance than AUD, but poor ink drying and printability, while AUD has excellent printability and ink dryness, but poor low temperature crack resistance. Seems.
