Description

유리섬유 보강 폴리카보네이트 수지 조성물 및 이를 이용한 성형품Glass fiber reinforced polycarbonate resin composition and molded article using same
본 발명은 유리섬유 보강 폴리카보네이트 수지 조성물 및 이를 이용한 성형품에 관한 것이다. 보다 구체적으로 본 발명은 비결정성 폴리에스테르 수지와 반응성 실란 화합물을 동시에 적용하여, 굴곡강도 저하 없이, 내충격성이 향상된 유리섬유 보강 폴리카보네이트 수지 조성물 및 이를 이용한 성형품에 관한 것이다.The present invention relates to a glass fiber reinforced polycarbonate resin composition and a molded article using the same. More specifically, the present invention relates to a glass fiber-reinforced polycarbonate resin composition and a molded article using the same by applying an amorphous polyester resin and a reactive silane compound at the same time, without reducing the bending strength.
폴리카보네이트 수지는 성형성과 내충격 특성, 인장 강도 등의 기계적 물성이 우수하고, 전기 특성, 투명성 등이 우수하여 자동차 및 전자제품 등에 폭넓게 사용되고 있다. 또한, 유리섬유 보강 폴리카보네이트 수지는 폴리카보네이트 수지가 가지는 우수한 성형성을 유지하면서도 강성 및 굴곡 강도를 향상시킬 수 있어 지속적으로 하중이나 열을 받아야 하는 부품에 유용하게 사용되고 있다.Polycarbonate resins are widely used in automobiles and electronic products because of their excellent mechanical properties such as moldability, impact resistance, tensile strength, and excellent electrical properties and transparency. In addition, glass fiber-reinforced polycarbonate resin can be used to improve the rigidity and flexural strength while maintaining excellent moldability of the polycarbonate resin is useful in parts that require continuous load or heat.
그러나, 폴리카보네이트 수지에 유리섬유를 첨가할 경우, 강성 및 굴곡강도는 향상되나 내충격성이 크게 감소하기 때문에 외부 충격에 의한 손상에 취약하다는 문제점이 있다. 따라서, 유리섬유 보강 폴리카보네이트 수지의 내충격성을 보강하기 위해 코어-쉘 그라프트 공중합체 등의 충격 보강제를 첨가하는 방안이 제안되었다. 그러나, 코어-쉘 그라프트 공중합체를 첨가할 경우, 폴리카보네이트 수지의 유동성이 감소하여 성형 사출 작업 온도를 높여야 하고, 이로 인해 유리섬유의 파괴가 심해져 굴곡 강도가 저하된다는 문제점이 있었다. However, when the glass fiber is added to the polycarbonate resin, the rigidity and flexural strength are improved, but since the impact resistance is greatly reduced, there is a problem in that it is vulnerable to damage caused by external impact. Therefore, in order to reinforce the impact resistance of the glass fiber reinforced polycarbonate resin, a method of adding an impact modifier such as a core-shell graft copolymer has been proposed. However, when the core-shell graft copolymer is added, the fluidity of the polycarbonate resin is reduced to increase the molding injection operation temperature, and thus, there is a problem that the breakage of the glass fiber is severe and the flexural strength is lowered.
