增强增光合金材料
本专利技术涉及高分子材料
,具体地说是一种具有增强增光性能的PC/PET合金。
技术介绍
聚碳酸酯(PC)是性能优异的工程塑料,具有冲击强度高、抗蠕变、尺寸稳定性好、耐热、透明、介电性能优良等优点,但是PC的熔体粘度大,耐溶剂性差,并且对缺口敏感,成本也高。聚对苯二甲酸乙二醇酯(PET)是一种半透明结晶型热塑性聚酯,具有高耐热性、韧性、耐疲劳性,自润滑、低摩擦系数,但PET的缺口冲击强度低,且易受卤化烃侵蚀,耐水解性差,成型收缩率大。将PC与PET共混得到的PC/PET合金,既具有PC刚性和耐热性,又具有PET的耐溶剂性,在PC/PET合金体系中加入第三组分,可进一步改善共混合金的性能。
