그리고 인공피혁에 미끄러짐을 방지(안티 슬립) 기능을 부여하기 위해 인공피혁 표면에 화학물질을 처리하여 미끄러짐을 방지할 수 있도록 하고 있다.In order to provide anti-slip (anti-slip) function to artificial leather, the surface of artificial leather is treated with chemicals to prevent slipping.
그러나, 내마모성의 향상을 위해 폴리우레탄 도막층을 고결정화하게 되면 인공피혁의 표면촉감 및 전체촉감이 유연하지 못하고 딱딱한 단점이 있었으며, 미끄러짐을 방지할 수 있게 된 인공피혁은 표면의 화학물질로 인해 끈적한 점성(TACKY성)이 남아 그 촉감이 좋지 못한 실정이었다.However, when the polyurethane coating layer is highly crystallized to improve abrasion resistance, the surface touch and overall feel of artificial leather are not flexible and have a hard disadvantage. Viscous (TACKY) remained and the touch was not good.

실시예 2.Example 2.
하기 표 2의 1차 코팅액(점도 : 25℃에서 20,000CPS±1,000) 및 2차 코팅액(점도 : 25℃에서 15,000CPS±1,000)으로 인공피혁을 제조하였다.The artificial leather was prepared as the primary coating solution (viscosity: 20,000CPS ± 1,000 at 25 ° C) and the secondary coating solution (viscosity: 15,000CPS ± 1,000 at 25 ° C).
본 실시예에서는 기재두께를 포함하여 1.5mm의 간격을 갖는 나이프 오버 롤 코팅기를 이용하여 기재에 1차 코팅액을 코팅한 후, 120-150℃로 순차적으로 건조시킨 후, 다시 2차 코팅액으로 2mm 나이프를 이용하여 직접 기재에 도포하여 건조 및 냉각시켰다.In this embodiment, the first coating liquid is coated on the substrate using a knife over roll coater having a thickness of 1.5 mm including the thickness of the substrate, and then sequentially dried at 120-150 ° C., and then again the 2 mm knife with the second coating liquid. It was applied directly to the substrate using the dried and cooled.
상기 실시예 1 및 2의 인공피혁은 폴리우레탄 수지에 함유된 타이어 분말로인해 독특한 외관 효과를 가지고, 미끄러짐성이 없었으며 내마모성 또한 우수한 것으로 판별되었다.Artificial leather of Examples 1 and 2 has a unique appearance effect due to the tire powder contained in the polyurethane resin, was not slippery, it was determined that the wear resistance is also excellent.
본 발명에 따른 폐타이어를 이용한 인공피혁은 미끄러짐성을 방지하기 위해 인공피혁 표면에 별도의 화학물질을 도포할 필요가 없고, 또한 미끄럼방지 물질이 도포되지 않음으로 인해 끈적한 점성을 갖지도 않게 되며, 타이어 소재 특유의 내마모성으로 인해 인공피혁에 내마모성을 부여할 수 있게 되는 한편, 독특한 외관 효과를 갖게 된다.Artificial leather using the waste tire according to the present invention does not need to apply a separate chemical to the surface of the artificial leather to prevent slippage, and also does not have a sticky viscosity due to the non-slip material is not applied, The wear resistance peculiar to the tire material makes it possible to impart wear resistance to artificial leather, and has a unique appearance effect.
그리고 환경오염을 유발하는 폐타이어의 활용처를 제공함으로써 환경오염 방지에 일조할 수 있는 효과가 있다.And by providing the utilization of waste tires that cause environmental pollution, there is an effect that can help to prevent environmental pollution.
