摘要

将聚对苯撑与聚氨酯进行共混

对共混材料的力学性能和耐热性能进行了试验研究

并通过 傅里叶红外光谱和扫描电子显微镜表征了其结构

以期从结构角度上认识该材料性能的变化规律. 结果表明:刚性聚对苯撑与聚氨酯的硬段间有一定程度的相容

因而加入聚对苯撑能改善聚氨酯的 拉伸强度和热稳定性;当聚对苯撑的质量增加至聚氨酯质量的15 %时

聚氨酯材料的拉伸强度提 高了1213 %

分解温度提高了12 ℃

耐热性能提高.

Abstract

Polyparap henylene (PPP) and Polyurethane (PU) were mixed sufficiently

and t he in2 fluence of PPP content in the PPP/ PU blends on t he mechanical and heat resistant performance was investigated experimentally. The microst ruct ure of t he blends was characteri-ed wit h Fourier t ransform inf rared spect roscopy

t hermogravimet ric analysis

and scanning elect ron microscope to obtain t he knowledge of st ructure2property relationship . The result s show t hat PPP serves as-fi2 ber-to st rengt hen t he blend ; t he intermolecular interaction or compatibility between PPP and t he hard segment of PU is revealed to a certain extent . The tensile st rengt h increases by 1213 % and t he heat degradation temperat ure increases by 12 -for PPP at the mass ratio of 15 % to PU.
