摘要
研究了在水合二氧化硅制备过程中对其产品质量的影响因素;乙烯基三乙氧基硅烷偶联剂(A-151)改性水合二氧化硅,改性水合二氧化硅具有良好的疏水性;并用改性水合二氧化硅补强丁苯橡胶,考察了补强后橡胶的拉伸强度、定伸应力等力学性能。当盐酸浓度为40%时制得的水合二氧化硅改性后补强丁苯橡胶所得复合材料综合性能最佳。
In this paper,the factors influencing product quality in the preparation of hydrated silica were studied.Triethoxy vinyl silanecoupling agent(A-151)modified silicon dioxide hydrate and silicone trioxide possessed good hydrophobicity.After using modified hydrated silicon dioxide for reinforcing styrene butadiene rubber,the mechanical properties such as tensile strength and tensile stress were investigated.When the concentration of hydrochloric acid is40%,the obtained composite has the best performance.
