摘要
分别采用自然凝固和酸凝固方法制备天然橡胶(NR),并比较2种方法凝固NR的交联密度、硫化特性、动态性能和生热等的差异。试验结果表明,自然凝固NR的交联密度和弹性模量较高,硫化速度快,动态损耗小,生热低。
The natural rubber(NR) was coagulated by acetic acid and natural coagulation process, and the crosslink density,curing behavior,dynamic properties and heat build-up of the NR were com- paratively studied. The results showed that,the crosslink density and elastic modulus of the NR from natural coagulation process were higher, the cure rate was faster, the dynamic loss was smaller, and the heat built-up was lower.
