Description
본 기재는 유리섬유 강화 열가소성 수지 조성물 및 이로부터 제조된 성형품에 관한 것으로, 보다 상세하게는 내충격성과 내광성이 모두 개선되고, 성형성이 우수한 유리섬유 강화 열가소성 수지 조성물 및 이로부터 제조된 성형품에 관한 것이다.
The present invention relates to a glass fiber-reinforced thermoplastic resin composition and a molded article produced therefrom, and more particularly to a glass fiber-reinforced thermoplastic resin composition which is improved in both impact resistance and light resistance and is excellent in moldability and a molded article produced therefrom .
일반적으로 열가소성 수지의 경우 화이트 색상을 내기 위해 다양한 안료를 사용할 수 있다. 이때 일반적인 비보강 수지의 경우에는 큰 물성의 저하가 없지만 유리섬유로 보강된 수지의 경우에는 안료가 유리섬유를 파괴할 수 있기 때문에 넣지 않았을 때에 비하여 충격강도, 인장강도 및 굴곡강도 등과 같은 기계적 물성이 크게 떨어지는 문제가 발생한다. 이러한 문제를 해결하기 위해 종래에 안료로 ZnS를 사용하는 방법, 안료의 투입량을 최소화하는 방법 및 압출조건을 완화하는 방법이 사용되고 있었다.In general, for thermoplastics, a variety of pigments can be used to achieve a white color. However, in the case of a resin reinforced with glass fiber, since the pigment can destroy the glass fiber, the mechanical properties such as impact strength, tensile strength and flexural strength, etc., There is a problem that it falls greatly. In order to solve this problem, conventionally, there have been used a method of using ZnS as a pigment, a method of minimizing the amount of pigment input, and a method of relaxing extrusion conditions.
그러나, 상기 ZnS를 사용하는 방법의 경우 ZnS는 유리섬유의 기계적 물성을 크게 떨어뜨리지는 않으나 내광성을 개선시키지 못해 장기 내광성이 요구되는 소재의 경우에는 사용할 수 없는 문제가 있다.However, in the case of the method using ZnS, ZnS does not significantly lower the mechanical properties of the glass fiber, but does not improve the light resistance and can not be used in the case of materials requiring long term light resistance.
또한, 상기 안료의 투입량을 최소화하는 방법의 경우 안료의 양을 매우 적게 넣어도 안료가 유리섬유를 깨뜨리는 것은 물리적인 현상이기 때문에 기계적 물성의 저하는 여전하며, 나아가 수지 자체의 낮은 내광성에 의한 색변화(ΔE 증가)가 다시 문제가 된다. Further, in the case of the method of minimizing the amount of the pigment, even if the amount of the pigment is very small The pigment The breaking of the glass fiber is a physical phenomenon, so the mechanical properties are still deteriorated, and further, the color change (increase in DELTA E) due to the low light resistance of the resin itself becomes a problem again.
마지막으로, 압출조건을 완화하는 방법(Screw configuration softening)의 경우 안료와 유리섬유 사이의 마찰을 줄여 유리섬유가 깨지는 것을 다소 줄일 수는 있으나, 분산이 균일하게 되지 않아 오히려 기계적 물성이 떨어지고, 사출 시에 여전히 유리섬유가 깨질 수 있는 위험이 존재하게 된다.
Finally, in the case of screw configuration softening, it is possible to reduce the friction between the pigment and the glass fiber to reduce the breaking of the glass fiber. However, since the dispersion is not uniform, the mechanical properties are lowered, There is still a risk that glass fibers may break.
상기와 같은 종래기술의 문제점을 해결하고자, 본 기재는 내충격성과 내광성이 모두 개선되고, 또한 성형성이 우수한 유리섬유 강화 열가소성 수지 조성물 및 이로부터 제조된 성형품을 제공하는 것을 목적으로 한다.
