| 中文摘要: |
| 研究白炭黑分散剂HST和H60EF对甲基乙烯基硅橡胶（MVQ）/丁苯橡胶（SBR）并用胶性能的影响。结果表明：在MVQ/SBR并用胶中加入白炭黑分散剂HST和H60EF，可加快胶料的硫化速度，改善分散性和加工性能，提高混炼效率；白炭黑分散剂HST对MVQ/SBR并用胶的动态力学性能无明显影响，可提高撕裂强度和耐老化性能，可用作MVQ/SBR并用胶的功能性助剂。 |
| 英文摘要: |
| The effects of silica dispersing agent HST and H60EF on the properties of methyl vinyl silicone rubber（MVQ）/styrene butadiene rubber（SBR） blend were studied.The results showed that，by adding silica dispersing agent HST and H60EF in the MVQ/SBR blend，the curing rate of compound increased，the dispersion，processability and mixing efficiency were improved.Silica dispersing agent HST had no obvious effect on the dynamic mechanical properties of MVQ/SBR blend，and could improve the tear strength and aging resistance.It could be used as a functional agent for MVQ/SBR blend. |
