Problems solved by technology

[0003] At present, most of the water-based paints or latex paints on the market are not breathable. Spraying or smearing on the wall surface will cause mildew on the wall surface and breed bacteria; although the content of harmful substances is below the national standard, there are still a lot of harmful substances in it. substances; and there are many problems such as short service life, easy wear and tear, not environmental protection, etc.

Abstract

The invention relates to a water-based coating using shell powder and a preparation method thereof. The water-based coating is prepared by the following steps of using the shell powder as the main rawmaterial, adding diatomite, calcium powder, kaolin and other additives, and mixing, so as to form the water-based coating using the shell powder. The water-based coating using the shell powder has the beneficial effects that the air ventilating property is good, the mildew-proof effect is realized, the poisonous substances are decomposed and adsorbed, and the air humidity is regulated; the environment-friendly effect is better, all adopted raw materials are substances containing no grease or benzene ring, and the finished product is free from toxicity or odor; the abrasion-resistant propertyis high, and the flame-retardant function is realized; the construction property is good, the construction method is flexible, and the water-based coating can be sprayed or coated.

Description

technical field [0001] The invention belongs to paint preparation technology, in particular to a water-based paint made from shell powder and a preparation method thereof. Background technique [0002] Any paint that uses water as a solvent or as a dispersion medium can be called a water-based paint. Water-based coatings are divided into two categories: natural water-based coatings of natural substances or minerals and synthetic resin water-based coatings. Water-based coatings of artificial synthetic resins include water-soluble coatings, water-dilutable coatings and water-dispersible coatings. Water-soluble coatings use water-soluble resins as film-forming materials, represented by polyvinyl alcohol and its various modified products, in addition to water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins. [0003] At present, most of the water-based paints or latex paints on the market are not breathable. Spraying or smearing on the...
