Abstract

The invention provides environment-friendly paint, and relates to the field of paint and coating. The environment-friendly paint comprises, in parts by weight, 8-12 parts of a film-forming assistant,15-25 parts of cellulose, 20-30 parts of water, 7-9 parts of titanium dioxide, 3-5 parts of zinc oxide, 5-10 parts of aluminum silicate, 5-15 parts of kaolin, 0.7-2 parts of a coupling agent, 0.5-6 parts of dispersant, 4-8 parts of defoamer, 3-7 parts of preservative, 1.5-2.5 parts of a pH regulator, 30-40 parts of styrene-acrylic emulsion, 0.5-6 parts of thickener, 1-3 parts of polyvinyl alcoholand 0.5-2 parts of sodium phosphate. The invention also provides a preparation method of the environment-friendly paint. Through the environment-friendly paint, the VOC content can be reduced, and notoxicity, no odor and no environmental pollution are produced after application of the environment-friendly paint.
