摘要
Abstract
Nine composites were prepared using three different chain extenders,namely 1,4-butanediol(BDO),4,4'-methylenebis(2-chloroaniline)(MCOA),and 4,4'-methylenebis(3-chloro-2,6-diethylaniline)(MCDEA),along with TDI-PTMEG prepolymer and hollow glass microspheres(HGM).The effects of HGM on the properties of polyurethane elastomers were investigated.The results showed that the addition of HGM significantly reduced the density of the composites and increased their hardness,but also decreased the tensile strength and elongation at break to some extent.However,HGM modified with a silane coupling agent(KH550)could ensure better mechanical properties of composites while maintaining a low density.The addition of modified HGM could reduce density of MCOA system by 21.0%,increase temperature of 50%weight loss by about 10℃,and achieve a tensile strength of 27.61 MPa.关键词
