补充资料:聚碳酸酯树脂复合材料
分子式:
CAS号:

性质:以聚碳酸酯树脂为基体、以填料填充或纤维(或其织物)增强的复合材料。聚碳酸酯分脂肪族与芳香族两类。有实用价值的是后者。最常见的是用双酚A与光气缩聚而成或由双酚A与二烷基或二芳基碳酸酯进行酯交换反应得到的线型高聚物。有结晶能力,但结晶速率低,在一般工艺条件下为无定形。净树脂有优良的综合性能:透明度高、刚度高、耐蠕变、尺寸稳定性好;韧性(尤其是低温韧性好),居一般热塑性塑料之首。但耐环境应力开裂能力较差。聚碳酸酯复合材料主要用玻璃纤维增强。纤维含量为1.0%~14%。复合材料制品主要用注射挤出和挤出吹塑工艺成型。与未增强聚碳酸酯相比,玻璃纤维增强聚碳酸酯的拉伸强度提高1~1.5倍,耐应力开裂能力提高5~7倍,耐热温度提高约15℃,线膨胀系数降低至1/4~1/2。已被用来代替金属用于汽车工业与仪表工业。还有用石墨、云母、滑石粉、玻璃珠填充的聚碳酸酯。近来还用玻璃纤维含量为5%~30%的增强聚碳酸酯注射成型大型泡沫结构。
