Abstract

본 발명은 장섬유가 함유된 열가소성 수지 조성물의 제조방법에 관한 것으로, Ⅳ 0.2~0.4정도의 저점도 상태의 열가소성 수지액에 유리섬유와 같은 장섬유를 총 조성물의 10~80% 함침시킨 후 이를 인발, 성형하고 절단한 후, 고상중합하여 고점도의 열가소성 수지 조성물로 만드는 방법이다.The present invention relates to a method for manufacturing a thermoplastic resin composition containing long fibers, Ⅳ 0.2 ~ 0.4 in a low viscosity thermoplastic resin solution impregnated 10 to 80% of the total composition of long fibers, such as glass fibers, and then After drawing, molding and cutting, it is a method of making a high viscosity thermoplastic resin composition by solid phase polymerization.

본 발명에 의하면 장섬유 사이에 충분히 수지를 함유시킬 뿐 아니라 공정중에 장섬유의 단절을 막을 수 있어 경제성이 높고 장섬유 함유 수지 특유의 물성증대를 꾀할 수 있다.According to the present invention, not only the resin is sufficiently contained between the long fibers, but also the breakage of the long fibers can be prevented during the process, so that the economic efficiency is high and the properties of the long fiber-containing resin can be increased.
