Abstract

The invention provides a flame-retardant inorganic interior wall coating and a preparation method thereof. The coating is prepared by mixing the following components comprising, by weight, 250-315 parts of deionized water, 3-5 parts of hydroxyethyl cellulose, 0.5-2 parts of bentonite, 3-8 parts of a stabilizer, 1-5 parts of a defoaming agent, 1-2 parts of a preservative, 100-250 parts of magnesiumhydroxide, 90-190 parts of titanium dioxide, 30-80 parts of calcined kaolin, 50-80 parts of 800# heavy calcium carbonate, 150-230 parts of inorganic potassium silicate, 50-100 parts of a styrene-acrylic emulsion and 2-5 parts of a thickener. The paint has the characteristics of flame retardancy, compactness, multicolor, scratch resistance, cracking resistance, dew formation resistance, mildew resistance, stain resistance, easiness in scrubbing and good storage stability.

Description

technical field [0001] The invention relates to the technical field of building decoration functional materials, in particular to a flame retardant inorganic interior wall coating and a preparation method thereof. Background technique [0002] Among the interior wall decoration materials of modern buildings, interior wall decoration paint is suitable for the interior decoration of various buildings, especially for The decoration of curved buildings has always occupied an important position in wall decoration at home and abroad. [0003] However, at present, most of the existing interior wall decoration paints are made of organic materials and inorganic mineral materials, which are flammable in case of fire, thus bringing potential safety hazards. In addition, the walls using the existing interior wall decoration paints still have soft hardness, easy Dirty, poor scratch resistance, easy to crack, and easy to condense during the rainy season. Contents of the invention [0...
