이하에는, 본 발명의 바람직한 실시예와 각 성분의 물성을 상세하게 설명하되, 이는 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 발명을 용이하게 실시할 수 있을 정도로 상세하게 설명하기 위한 것이지, 이로 인해 본 발명의 기술적인 사상 및 범주가 한정되는 것을 의미하지는 않는다.Hereinafter, a preferred embodiment of the present invention and the physical properties of each component will be described in detail, which is intended to describe in detail enough that a person of ordinary skill in the art to which the present invention pertains can easily carry out the invention, This does not mean that the technical spirit and scope of the present invention is limited.
본 발명에 따른 내마모성이 우수한 섬유 코팅용 조성물은 주재 100 중량부 및 경화제 10 내지 40 중량부로 이루어진다.The composition for coating fibers having excellent abrasion resistance according to the present invention consists of 100 parts by weight of the main material and 10 to 40 parts by weight of the curing agent.
상기 주재 대비 경화제의 함량이 10 중량부 미만이면 섬유 코팅용 조성물의 경화가 더디게 진행되어 건조가 더디게 진행될 뿐만 아니라, 내황변성이 낮아지고, 상기 경화제의 함량이 40 중량부를 초과하게 되면 경화가 빠르게 진행되어 섬유 코팅용 조성물의 가사시간이 지나치게 짧아지게 된다.If the content of the curing agent compared to the main material is less than 10 parts by weight, the curing of the composition for coating fibers proceeds slowly, and not only the drying proceeds slowly, but also the yellowing resistance is lowered, and when the content of the curing agent exceeds 40 parts by weight, curing proceeds quickly Thus, the pot life of the composition for coating fibers becomes too short.

Not only is this excellent, but it also exhibits good compatibility with the polyether polyol contained in the curing agent, and exhibits an effect that physical properties are not deteriorated even at high temperatures.
[화학식 1][Formula 1]
상기의 화학식 1을 나타내는 폴리카르보네이트디올은 폴리에테르 폴리올이 갖는 피착제에 대한 낮은 점착력과 폴리에스테르 폴리올이 갖는 섬유가공성이 낮고, 건조가 늦은 단점 등을 해소할 수 있다.The polycarbonate diol represented by the above formula (1) can solve the disadvantages of low adhesion to an adherend of polyether polyol, low fiber processing property of polyester polyol, and slow drying.
