Abstract

본 발명은 열가소성 폴리아미드수지 조성물의 제조방법에 관한 것으로, 2개의 투입구가 있는 이축압출기를 사용하여 폴리아미드수지 20~90중량%와 폴리올레핀 10~80중량%로 이루어진 수지 100중량%에 대하여, 폴리아미드, 폴리올레핀과 무수말레인산, 푸메린산, 아크릴산 중에서 선택된 관능기 0.01~10중량%, 과산화물 0.005~0.5 중량%를 혼합하여 동력부에서 다이방향으로 제1투입구로, 내열제 0.02~2 중량제%는 제2 투입구로 투입하는 것을 특징으로 하는 열가소성 폴리아미드수지 조성물의 제조방법이다.The present invention relates to a method for producing a thermoplastic polyamide resin composition, using a biaxial extruder having two inlets, with respect to 100% by weight of a resin consisting of 20 to 90% by weight of polyamide resin and 10 to 80% by weight of polyolefin. From 0.01 to 10% by weight of functional groups selected from amide, polyolefin, maleic anhydride, fumeric acid, and acrylic acid, and 0.005 to 0.5% by weight of peroxide, the first portion of the power unit is in the direction of the die, and the heat resistant agent is 0.02 to 2% by weight. A method for producing a thermoplastic polyamide resin composition, characterized in that it is introduced into the second inlet.

본 발명의 특징은 두 단계 이상의 공정을 거쳐야 했던 종래기술의 문제점을 해결한 것으로, 경제성, 생산성이 우수하고, 기계적 물성, 성형성, 난연성이 우수하면서도 특히 수분흡수율을 개선하여 물성유지율이 우수한 수지조성물로 자동차, 전기, 전자 부품에 광범위하게 적용될 수 있다.A feature of the present invention is to solve the problems of the prior art, which had to go through two or more steps. The resin composition is excellent in economics and productivity, and has excellent mechanical properties, moldability, and flame retardancy, and particularly improves water absorption. It can be applied to a wide range of automotive, electrical and electronic components.
