摘要
采用聚四氢呋喃多元醇2000(PTMG 2000)、甲苯二异氰酸酯(TDI)合成了NCO封端的预聚体,然后分别采用4,4'-亚甲基-双(3-氯-2,6-二乙基苯胺)(MCDEA),3,3'-二氯-4,4'-二氨基二苯基甲烷(MOCA)以及2,4-二胺基-3,5-二甲硫基甲苯(E-300)进行扩链,并对制得的浇注型聚氨酯弹性体(CPUE)试片进行力学性能和耐溶剂性能的测定,分析并探讨了扩链剂种类对CPUE力学性能和耐溶剂性能的影响,为浇注型聚氨酯弹性体在胶辊、胶轮的应用推广提供参考。
A series of NCO terminated prepolymers were prepared by adopting polytetrahydrofuran poly- ols and toluene diisocyanate. Mechanical properties and solvent resistance performance of the CPUE samples extended by three chain extenders which were MCDEA, MOCA, E-300 were characterized. The effect of chain extender structure on mechanical properties and solvent resistance performance of CPUEs was discussed. It was useful for the application of CPUE on the roller and wheel.
