| 摘 要： | 研究锌皂分散剂、偶联剂KH-560及其并用对白炭黑填充硅橡胶性能的影响。结果表明,锌皂分散剂和偶联剂KH-560均能弱化填料网络结构,促进白炭黑的分散,减小胶料在低应变下的储能模量,且二者并用效果更佳;结合胶质量分数增大表明偶联剂KH-560和锌皂分散剂并用能够提高填料与硅橡胶间的相互作用;锌皂分散剂的加入明显缩短了胶料的正硫化时间,在保证操作安全的前提下,显著加快了硫化速率;偶联剂KH-560改性白炭黑体系中加入少量的分散剂,硫化胶的硬度、100%和300%定伸应力、拉伸强度呈增大趋势,拉断伸长率减小。

| Abstract: | The effect of zinc soap dispersant,coupling agent KH-560 and their blend on the properties of silica filled MVQ was investigated.The results showed that,by adding the dispersant or coupling agent KH-560,the filler network structure was weakened,the dispersion of silica in MVQ compound was improved,the storage modulus of compound at low strain was reduced and a stronger effect was gained in their blend.The increased bound rubber indicated that,the silica-rubber interaction was enhanced by coupling agent KH-5... |
