一种玻璃纤维增强PBT/ASA合金及其制备方法
摘要：
本发明提供一种玻璃纤维增强PBT/ASA合金及其制备方法。本发明提供的玻璃纤维增强PBT/ASA合金包括以下质量含量的组分：聚对苯二甲酸丁二醇酯50～65％，丙烯腈‑苯乙烯‑丙烯酸酯共聚物10～20％，玻璃纤维10～30％，聚甲基丙烯酸甲酯3～10％，抗氧剂0.2～0.8％和润滑剂0.1～0.6％。本发明提供的玻璃纤维增强PBT/ASA合金以聚甲基丙烯酸甲酯为相容增韧剂改善了玻璃纤维、PBT和ASA间的相容性，同时起到提高韧性的作用，提高合金强度，且通过各组分的相互配合，无需额外添加增韧剂即可具有良好的冲击强度。
摘要（英）：

The invention provides glass fiber reinforced PBT/ASA alloy and a preparation method thereof. The provided glass fiber reinforced PBT/ASA alloy comprises, by mass, 50-65% of polybutylene terephthalate, 10-20% of acrylonitrile-styrene-acrylate copolymer, 10-30% of glass fibers, 3-10% of polymethyl methacrylate, 0.2-0.8% of antioxidant and 0.1-0.6% of lubricant. According to the glass fiber reinforced PBT/ASA alloy, polymethyl methacrylate is used as a compatible toughening agent, so that the compatibility among the glass fibers, PBT and ASA is improved, and meanwhile the toughness and the strength of the alloy are improved. In addition, through mutual cooperation of the components, good impact strength can be achieved without additionally adding a toughening agent.
