摘要: 通过电导率对乙烯基三乙氧基硅烷偶联剂(A-151)的水解行为进行研究,考察了pH、水与A-151体积比和温度对硅烷水解行为的影响,利用A-151的水解特性,对经锆铝二元包覆后的钛白粉进行表面改性,并采用表面接触角测试仪、红外光谱和扫描电镜对有机改性后的二氧化钛进行表征。表面接触角测试显示改性后的二氧化钛制片表面润湿角达108.2°;改性后的粉体在波数为3 078 cm-1处出现了对应的烯烃C—H伸缩振动吸收峰;扫描电镜照片显示改性后的二氧化钛粒子的分散性得到了改善。

Abstract: Properties of the hydrolysis of the vinyl triethoxy silane coupling agent(A-151) were analyzed by conductivity. The influences of pH,volume ratio of water to A-151,and temperature on the hydrolysis of silane were investigated.By utilizing the hydrolysis characteristic of A-151,surface modification of titanium dioxide,which was coated with zirconium and aluminum composites,was carried out.And then the organic modified titanium dioxide was characterized by surface contact angle instrument,FT-IR,and SEM.Results showed that the surface contact angle of modified titanium dioxide was 108.2°,the modified powders appeared of a peak at 3 078 cm-1 which was corresponding to the olefin C—H stretching vibration,and the SEM photos showed the dispersion of the modified titanium dioxide was improved.

Key words: titanium dioxide, silane coupling agent, hydrolysis, surface modification
