摘　　要：研究恒粘剂硫酸联胺对天然橡胶(NR)硫化特性的影响。结果表明:在NR中加入恒粘剂硫酸联胺,胶料的t_(10)缩短,t_(90)延长;随着硫化温度的升高,NR和恒粘天然橡胶(CVNR)胶料的t_(10)和t_(90)缩短,NR胶料的t_(10)对温度的依赖性小于CVNR胶料,t_(90)对温度的依赖性大于CVNR胶料;NR胶料的t_(10)对t_(90)的影响灵敏度大于CVNR胶料;NR和CVNR胶料的M_H随硫化温度的升高而减小。The effect of viscosity stabilizer diammonium sulfate on the curing characteristics of NR compound was investigated. The results showed that, by adding viscosity stabilizer diammonium sulfate in NR compound, the t10 of the compound was shortened and t90 was extended. As curing temperature increased, the t10 and/90 of NR or constant viscosity NR（CVNR） compound were shortened. The dependence of t10 on the temperature of NR compound was smaller than that of CVNR compound, and the dependence of t90 on the temperature of NR compound was greater than that of CVNR compound. The sensitivity of t10 on t90 of NR compound was greater than that of CVNR compound. The MH of NR and CVNR compound were decreased as the curing temperature increased.
