| 中文摘要: |
| 研究了多元醇(1，2-丙二醇、一缩二乙二醇、丙三醇)和硅烷偶联剂A151等配合剂对甲基乙烯基硅橡胶(MVQ)硫化胶性能的影响。试验结果表明，1，2-丙二醇在胶料中起结构控制剂的作用；在胶料中同时加入少量1，2-丙二醇和偶联剂A151，可以获得低模量、高扯断伸长率的硅橡胶材料；结构控制剂DS用量以4#气相法白炭黑用量的20%为宜；丙三醇可改善MVQ硫化胶的补强效果。 |
| 英文摘要: |
| The effect of the ingredients，such as polyols(1，2-propyleneglycol，diglycol and propylenetriol)and silane coupling agent A151 on the properties of MVQ vulcanizate was investigated.The test results showed that 1，2-propyleneglycol acted as a structure controlling agent；the addition of small amount of 1，2-propyleneglycol and coupling agent A151 to the compound resulted in a silicone rubber with low modulus and high elongation at break；the suitable level of structure controlling agent DS was equal to 20% loading level of 4# gas silica；the propylenetriol could improve reinforcement of MVQ vulcanizate. |
