Abstract

The invention discloses an environmentally-friendly composite interior wall coating material and a preparation method thereof. The environmentally-friendly composite interior wall coating material comprises the following components in percentage by mass: 18-25% of water, 15-20% of polyvinyl acetate emulsion, 10-15% of GHT-2DS pure acrylic emulsion, 15-20% of 800-mesh anatase titanium dioxide, 15-20% of 800-mesh light calcium carbonate, 5-8% of 800-mesh talcum powder, 4.7-7% of 800-mesh bentonite, 0.72-2.0% of lauryl alcohol ester, 0.04-0.94% of ultramarine, 0.01-0.06% of S-220 defoaming agent, and 0.01-0.06% of BEK-500 sterilizing agent. The environmentally-friendly composite interior wall coating material has the advantages of environmental protection, alkali resistance, scrubbing resistance and the like. The drying time and the storage period of the environmentally-friendly composite interior wall coating material are obviously prolonged, and the contrast ratio of the environmentally-friendly composite interior wall coating material is obviously increased; and all the indexes of the environmentally-friendly composite interior wall coating material meet and exceed GB / T9756-2001 and GB18583-2001 national standards.
