Polymerization of Silicone Modified Acrylate Emulsion and Preparation of Self-Cleaning Exterior Wall Paint
Vinyl triethoxyl silicane, hydrogen silicone oil and microcrystal wax were separately used to modify the acrylic emulsion, wollastonite and synthesize the silicone wax emulsion for preparing exterior wall paint. The optimum conditions for the modifications and synthesis were experimentally presented. Under the optimum formula and operation conditions the silicone-modified acrylic emulsion exhibited good quality and all the property indexes of the exterior wall paint with a contact angle of about 140° were better than those regulated in the national standards issued by Chinese government. The structure of the modified acrylate emulsion, measured by infrared spectroscopy, was proved to be a real silicate-acrylate copolymerization emulsion.
