유리섬유 강화 ABSFiberglass Reinforced ABS

열가소성 수지의 치수안정성, 내크립성 또는 강성을 보강하기 위한 일반적인 기술로는 유리섬유를 보강재로 사용하는 것을 들 수 있다. 그러나 유리섬유를 보강재로 사용함에 따라 성형시 금형에서의 이형성이 저하되어 핀백화 또는 크랙이 발생하여 제품의 질을 떨어뜨리고, 이형불량으로 인하여 작업성이 저하되는 문제점이 있다.As a general technique for reinforcing the dimensional stability, creep resistance, or rigidity of the thermoplastic resin, it is possible to use glass fiber as a reinforcing material. However, as the glass fiber is used as a reinforcing material, the releasability in the mold is lowered during molding, resulting in pinback or cracking, thereby lowering the quality of the product and deteriorating workability due to mold release defects.

이러한 문제점을 해결하기 위한 종래의 기술로는 실리콘 오일, 금속계 활제, 왁스 등을 첨가하는 방법이 있으나 이 경우에는 강성이 저하되는 또 다른 문제점이 발생한다.Conventional techniques for solving this problem include a method of adding a silicone oil, a metal-based lubricant, wax, etc. In this case, another problem of stiffness deteriorates.

It became.

본 발명은, (A) 공역 디올레핀을 주체로 한 고무성분 30∼60중량%를 함유하고, 적어도 아크릴로니트릴과 방향족 비닐을 함유하고, 메타크릴산 에스테르를 함유하지 않거나 방향족 비닐의 함유량을 초과하지 않는 범위 내에서의 메타크릴산 에스테르를 함유한 수지성분 40∼70중량%를 함유한 그라프트 중합체 45∼90중량%와, (B) PBT수지 5∼15중량%로 구성된 조성물에, (C) 사이징 처리된 유리단섬유 5∼40중량%를혼합하는 것을 특징으로 한다.The present invention contains (A) 30 to 60% by weight of a rubber component mainly composed of a conjugated diolefin, contains at least acrylonitrile and aromatic vinyl, does not contain methacrylic acid ester or exceeds the content of aromatic vinyl To a composition composed of 45 to 90% by weight of the graft polymer containing 40 to 70% by weight of the resin component containing methacrylic acid ester and (B) 5 to 15% by weight of the PBT resin, 5 to 40% by weight of the glass fiber shortened by sizing.
