Abstract
Description
본 발명은 고분자 수지 자체에 가교성 관능기를 도입하고 이를 경화제와 반응시켜 분자 간 결합을 도입함으로써, 별도의 첨가제를 사용하지 않고도 오염방지 및 가수분해 방지 성능과 기계적 특성을 향상시킬 수 있도록 하는, 섬유소재의 표면 보호를 위한 경화성 코팅제 조성물 및 이를 이용한 코팅 원단 제조 방법에 관한 것이다.The present invention introduces a cross-linkable functional group into a polymer resin itself and reacts it with a curing agent to introduce an intermolecular bond, thereby improving anti-fouling and anti-hydrolysis performance and mechanical properties without using a separate additive. It relates to a curable coating composition for protecting the surface of a material and a method for manufacturing a coated fabric using the same.
일반적으로 각종 섬유, 필름, 가죽 등의 경우 내구성 등의 보완을 위해 표면 코팅제를 사용하고 있으며, 특히 최외곽에는 주로 고분자 코팅 수지가 사용된다. 특히, 각종 원단의 최외곽에 스크린 인쇄를 통한 인쇄층이 적용될 경우 이를 외부 환경(수분, 오염물질 등)으로부터 보호하기 위해 표면 보호용 코팅제가 코팅된다.In general, in the case of various fibers, films, leather, etc., a surface coating agent is used to supplement durability, and in particular, a polymer coating resin is mainly used for the outermost part. In particular, when a printed layer through screen printing is applied to the outermost surface of various fabrics, a coating agent for surface protection is coated to protect it from the external environment (moisture, contaminants, etc.).
한편, 종래 기술로써 고분자 코팅 수지를 기반으로 한 표면 코팅제의 오염방지 및 가수분해 방지 성능을 향상시키기 위해 실리카, 왁스 및 실란커플링제 등의 첨가제를 적용하고 있는데, 이는 소량 사용 시 상기 기능의 향상 효과가 없으며, 과량 사용 시 표면으로 마이그레이션(migration) 되거나 변색이 일어나고, 각종 원단(섬유원단, 가죽원단 및 필름 등)의 기재로부터 부착성이 떨어지는 문제점이 있다. 그리고 분산을 위한 공정이 추가로 요구될 뿐만 아니라 분산 안정성에 한계가 있어 저장 안정성이 좋지 못한 문제점이 있다.On the other hand, as a prior art, additives such as silica, wax, and silane coupling agent are applied to improve the antifouling and antihydrolysis performance of a surface coating agent based on a polymeric coating resin, which improves the function when used in a small amount. There is no, there is a problem that migration (migration) or discoloration occurs on the surface when used in excess, and the adhesion from the base material of various fabrics (textile fabric, leather fabric, film, etc.) is poor. In addition, there is a problem in that storage stability is not good due to a limitation in dispersion stability as well as an additional process for dispersion is required.
이를 해결하기 위하여 오염방지 및 가수분해 방지 성능을 향상시키기 위해 특허문헌 1 내지 3에서와 같이, 불소 화합물을 사용한 기술이 공개되었으나, 불소화합물의 경우 고가이고 과불화화합물의 경우 규제 대상물질에 해당되기 때문에 과량 및 지속적으로 상용하기 어려운 문제점이 있다.In order to solve this problem, technologies using fluorine compounds have been disclosed as in Patent Documents 1 to 3 to improve anti-fouling and anti-hydrolysis performance, but fluorine compounds are expensive and perfluorinated compounds are subject to regulation. Therefore, there are problems in that it is difficult to use excessively and continuously.
즉, 종래 기술에 따른 실리카, 왁스, 실란커플링제 및 불소화합물의 경우 과량 사용 시 오염방지 및 가수분해 방지 성능이 일부 구현되지만, 변색, 분산 및 저장안정성 문제 등으로 사용할 수 있는 양이 한정적이며 과량 사용하기에는 어려운 문제점이 있다.That is, in the case of silica, wax, silane coupling agent and fluorine compound according to the prior art, contamination prevention and hydrolysis prevention performance are partially implemented when used in excess, but the amount that can be used is limited and excessive due to discoloration, dispersion and storage stability problems There are problems with using it.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 섬유소재의 표면 코팅제로 사용되는 고분자 수지에 별도의 첨가제(실리카, 왁스 및 실란커플링제 등)나 불소화합물을 사용하는 종래기술과 달리, 고분자 수지 자체에 가교성 관능기를 도입하고 이를 경화제와 반응시켜 분자 간 결합을 도입함으로써, 별도의 첨가제를 사용하지 않고도 오염방지 및 가수분해 방지 성능과 기계적 특성을 향상시킬 수 있도록 함을 과제로 한다.The present invention is to solve the above problems, unlike the prior art using a separate additive (silica, wax, silane coupling agent, etc.) or a fluorine compound to the polymer resin used as a surface coating agent for textile materials, polymer resin By introducing a cross-linkable functional group into itself and reacting it with a curing agent to introduce an intermolecular bond, the task is to improve anti-fouling and anti-hydrolysis performance and mechanical properties without using a separate additive.
본 발명은 카르복실기 함유 수분산 우레탄 수지(carboxyl group containing waterborne polyurethane resin) 80 ~ 98 중량%, 경화제 1 ~ 10 중량% 및 아크릴 폴리머(acrylic polymer) 1 ~ 10 중량%를 포함하는 것을 특징으로 하는, 섬유소재의 표면 보호를 위한 경화성 코팅제 조성물 및 이를 이용한 코팅 원단 제조 방법을 과제의 해결 수단으로 한다.The present invention is a fiber, characterized in that it comprises 80 to 98% by weight of a carboxyl group containing waterborne polyurethane resin, 1 to 10% by weight of a curing agent, and 1 to 10% by weight of an acrylic polymer. A curable coating composition for protecting the surface of a material and a method for manufacturing a coated fabric using the same are a means of solving the problems.
여기서, 상기 카르복실기 함유 수분산 우레탄 수지는 카르복실기 함유 단량체와 중화제의 비율이 1 : 0.05 ~ 1 : 0.95 중량비로 하여 합성되는 것이 바람직하다.Here, the carboxyl group-containing aqueous dispersion urethane resin is preferably synthesized at a weight ratio of 1:0.05 to 1:0.95 between the carboxyl group-containing monomer and the neutralizing agent.
