摘　　要：实验中选择7/3的PC/PBT配比,无水磷酸二氢钠做为酯交换抑制剂,MBS和功能树脂作为抗冲改性剂,双酚A双(二苯基磷酸酯)作为阻燃剂,PC-PBT共聚物作为相容剂的玻璃纤维增强PC/PBT材料。结果显示材料悬臂梁缺口冲击强度达到125 J/m,拉伸强度达到135 MPa,弯曲强度达到210 MPa。耐高温性能优异,本实验样品热变形温度(HDT)可以达到126℃,能够满足需求。阻燃性能达到UL94 V-0阻燃等级。7/3 ratio of PC/PBT,anhydrous sodium dihydrogen phosphate as transesterification inhibitor,MBS and functional resin as impact modifier,bisphenol-A bis( diphenylphosphate) as flame retardant,PC-PBT copolymer as compatibilizer were selected as glass fiber reinforced PC/PBT materials. The results showed that the notched impact strength and tensile strength of material were 125 J/m and 135 MPa,respectively,high bending strength reached210 MPa,the heat deflection temperature( HDT) was 126 ℃,which can meet the demand. The flame retardant property achieved UL94 V-0 flame retardant grade.
