一种耐热PBT-PP合金及其制备方法
摘要：
本发明涉及一种耐热PBT-PP合金及其制备方法。本发明提供的耐热PBT-PP合金，包括以下重量份的组分：PBT75～90重量份，PP45～60重量份，玻璃纤维30～45重量份，相容剂10～15重量份，聚醚酰亚胺20～35重量份，苄叉丙酮15～25重量份，润滑剂1.5～2重量份，四季戊四醇酯2～5重量份。本发明的技术方案通过合理的配比以及各组分的组合既能够满足高的耐热性、高的力学性能、耐化学试剂性、耐候性、优异的电性能和吸水率低又能够有较高的耐老化性、尺寸稳定性和加工性能显著的翘曲度和表面光洁度，同时还具有较高的表面光泽度和翘曲度，并且其制备工艺简单、成本低。
摘要（英）：

The invention relates to a heat-proof PBT-PP alloy and a preparation method thereof. The heat-proof PBT-PP alloy comprises the following components in parts by weight: 75-90 parts of PBT, 45-60 parts of PP, 30-45 parts of glass fiber, 10-15 parts of a compatilizer, 20-35 parts of polyetherimide, 15-25 parts of benzylidene acetone, 1.5-2 parts of a lubricant, and 2-5 parts of pentaerythritol. Through reasonable ratio and combination of the components, the PBT-PP alloy can satisfy high heat resistance, high mechanical property, chemical reagent resistance, weatherability, excellent electrical property, low water absorption, high aging resistance, size stability and obvious processing property, high warping degree and surface fineness. The preparation method has the advantages of simple process and low cost.
