Abstract: |
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 t90 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. |
