硅烷偶联剂水解及对钛白粉的改性研究

Abstract

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
