摘要:

在聚氧化丙烯多元醇(PPG)和二苯基甲烷二异氰酸酯(MDI)组成的交联聚氨酯(CPU)体系的基础上添加聚醚改性MQ树脂(E-MQ),制备出E-MQ树脂增强的浇注型聚氨酯弹性体。结果表明：E-MQ树脂与CPU有良好的相容性,制备出的E-MQ增强弹性体具有良好的力学性能。当E-MQ树脂用量为8%(E-MQ树脂占聚氨酯弹性体总质量分数)时增强聚氨酯弹性体的拉伸强度可达20.8 MPa,比CPU基础样提高22.4%,撕裂强度为82 kNm^-1,邵尔A硬度为82度。

Abstract：

Based on a cross-linked polyurethane (CPU) system composed of polyoxypropylene polyol (PPG) and diphenylmethane diisocyanate (MDI), a kind of polyether modified MQ (E-MQ) resin was added to prepare E-MQ reinforced pouring type CPU elastomer. The results show that the E-MQ resin has good compatibility with the CPU, and the prepared E-MQ resin reinforced elastomer has excellent mechanical properties. When the content of E-MQ resin is 8% (E-MQ resin accounts for the total mass fraction of the CPU) the tensile strength of polyurethane elastomer reached to 20.8 MPa, increased by 22.4% comparing to the basic CPU, tear strength is 82 KNm^-1, Shore A hardness is 82 degrees.

Key words： polymer material polyurethane elastomers polyether modified MQ resin tensile strength thermal resistance
