Water-based environment-friendly anti-rust internal wall building coating and preparation method thereof

Abstract

The invention discloses a water-based environment-friendly anti-rust internal wall building coating and a preparation method thereof. The coating comprises the following components by weight percent: 25%-30% of water, 2%-5% of propanediol, 15%-20% of GHS98A-302 silicone acrylic emulsion, 12%-16% of GH-26XB silicone acrylic anticorrosion emulsion, 3%-8% of 1,000-mesh superfine calcium zinc phosphate powder, 3%-7% of 1000-mesh WD-S-800 superfine iron-titanium compound powder, 12%-16% of 1,000-mesh superfine rutile titanium dioxide powder, 5%-12% of 1,000-mesh superfine talcum powder, 2%-5% of alcohol ester-12(DN-12), 0.5%-2% of a DA dispersant, 0.1%-0.3% of a GHP thickening agent, 0.1%-0.3% of a water-based de-foaming agent JS-R201 and 0.1%-0.3% of a sterilizing preservative LC-18. The coating does not contain heavy metal, is environment-friendly, has the characteristics of high drying speed, water resistance, acid resistance, alkali resistance, chemical drug corrosion resistance, scrub resistance, artificial weathering aging resistance, good adhesion, salt mist resistance, good rust resistance and the like, and has good application prospects; the emission of VOC (volatile organic compounds) is zero.

Description

technical field [0001] The invention relates to a water-based environmental protection antirust interior wall architectural coating and a preparation method thereof, which are mainly used in the field of architectural decoration. Background technique [0002] In recent years, scientists and technicians in the field of coatings at home and abroad have achieved certain results in the research of anti-rust coatings, but there are few studies on water-based environmental protection anti-rust interior wall architectural coatings. At present, when decorating the interior walls of buildings, before the interior wall paint is painted, there are many nail holes. These nail holes are dried with putty without anti-rust paint, and then painted. After half a year, there are nail holes everywhere, especially It is ugly and seriously affects the decorative effect. Therefore, before applying the putty, first apply the anti-rust paint to the nail holes, and then apply the paint after the pu...
