中文摘要: |
对软质PU弹性体用预聚体及使用技术进行研究。试验结果表明,采用复合聚己二酸酯、80/20二异氰酸甲苯酯体系,以三羟甲基丙烷为固化剂,加入特制的稀释剂,并配以独特的工艺,可制得性能与进口同类产品水平相当的预聚体及相应弹性体制品。 |
英文摘要: |
The preparation of prepolymer for soft PU elastomer and its application were investigated.The test results showed that the prepolymer and finished product of soft PU elastomer with the properties comparable to those of the imported ones were obtained by using complex polyadipate,80/20 toluene diisocyanate (TDI),trimethylol propane and special diluent. |
