Study on Synthesis of In Situ Composite of Nano-TiO₂ and Vinyl Acetate-Acrylate Emulsion

Abstract:

Nanometer titanium dioxide has not only small size effect, quantum dimension effect, surface and interface effects and macroscopic quantum tunnel effect, but also photocatalytic effect. Vac-acrylate emulsion is one of the important emulsion adhesive. It has good properties for coating, high cohesive strength, no pollution. It has the special functions with few nano-TiO₂.In this paper, method of modification about nanometer TiO₂ was introduced via cellulose sodium. The modified nanometer titanium dioxide was added to the material of the preparation of acrylic emulsion including vinyl acetate, butyl acrylate, acrylic acid and methyl methacrylate to synthesize composite of nano-TiO₂/vac-acrylic emulsion. According to the performance analysis of solid content of emulsion and stabilization, we can find that when the use level of dosage, emulsifier, nano-TiO₂ is 0.5%, 3.2%, 0.7%, and emulsion has the best combination property.
