| 摘 要： | 采用新鲜天然胶乳分别制备乙酸凝固NR(NR-1)、微生物凝固NR(NR-2)、乙醇胺混合微生物凝固NR(NR-3)和蛋白酶混合自然凝固NR(NR-4),研究制备工艺对NR性能的影响。结果表明:NR-1和NR-2生胶的耐热老化性能和热稳定性好于NR-3和NR-4生胶;NR-4胶料的MH最大,t90最短,NR-3胶料的MH较小,t90最长;NR-4硫化胶的定伸应力和拉伸强度较大,拉断伸长率较小,NR-1硫化胶的定伸应力和拉伸强度较小;NR-4生胶、混炼胶和硫化胶的弹性转矩(S′)和剪切储能模量(G′)最大,损耗因子(tanδ)最小,NR-1生胶、混炼胶和硫化胶的S′和G′最小,tanδ值最大。

| Abstract: | Four kinds of NRs were obtained by coagulating the fresh NR latex(NRL) with dif-ferent processes:NRL coagulated by acetic acid(NR-1),NRL coagulated by microorganism(NR-2),ethanolamine-blended NRL coagulated by microorganism(NR-3),and protease-blended NRL coagulated naturally(NR-4).The effect of preparation processes on the properties of NR was investigated.The results showed that,the raw NR-1 and NR-2 possessed better thermal aging property and thermal stability than the raw NR-3 and NR-4.The MH of NR-4 com... |
