Abstract

The invention relates to a preparation method of diatom mud environment-friendly interior wall coatings. The preparation method comprises the following steps of: firstly preparing the following materials in parts by weight: 20 of diatomite (325 meshes), 8 of adhesive powder, 0.6 of methyl cellulose, 7 of talc powder (700 to 900 meshes), 15 of calcium carbonate powder (400 to 600 meshes), 10of quartz sand (20 to 90 meshes), 10 of kaolin (750 to 850 meshes), 2 of attapulgite powder (550 to 750 meshes), 2 of titanium dioxide powder, 10 of ash calcium powder (550 to 650 meshes), 14.7 of r heavy calcium carbonate (1200 to 1300 meshes), 0.4 of wood fibers and 0.3 of staple fibers; loading the above materials into a horizontal high-speed dispersion machine according to the given ratio; and dispersing uniformly. The preparation method provided by the invention can produce novel interior wall coatings which are free of VOC (volatile organic compounds), temperature-resistant, fire-proof and wear-resistant and have stable performances, and a long useful service life.

Description

technical field [0001] The invention relates to the field of paint manufacturing, in particular to a preparation method of a novel diatom mud environmental protection interior wall paint. Background technique [0002] At present, the interior wall decoration materials on the market are mainly water-based emulsion paints, also known as latex paints, which are divided into two categories: polyvinyl acetate emulsions and acrylic emulsions. All kinds of decorations, the decoration effect is simple and elegant, and it is widely used. Our country began to develop and produce in the 1980s, and there are dozens of varieties and models up to now. Their basic properties are the same, and they are basically composed of water, pigments, emulsions, fillers and various additives. However, this kind of interior wall paint made of emulsions, additives, etc. has disadvantages such as VOC emissions, no fire resistance and temperature resistance, and heavy metals.
