Problems solved by technology

However, these environmentally-friendly latex paints cannot be directly painted on the wall, and putty is used as the bottom layer. During the construction of the putty, glue containing formaldehyde will be added. After the decoration, the formaldehyde in the putty will slowly volatilize, which will also cause pollution and damage to homes and public places.

Abstract

The invention discloses formaldehyde-free building paint. The formaldehyde-free building paint is prepared by, by weight, 25-35 parts of water-based fluorocarbon emulsion, 6-12 parts of ethylene glycol tertiary butyl ether, 5-7 parts of polyaniline-graphene hollow microspheres, 2-7 parts of clove oil, 6-10 parts of ZSM molecular sieve, 8-12 parts of ceramic fibers, 8-12 parts of dibutyltin dilaurate, 10-15 parts of sepiolite powder, 3-8 parts of radix lithospermi oil, 25-35 parts of softened water, 2-5 parts of defoaming agent, 2-7 parts of defoaming agent, 2-7 parts of dispersing agent, 2-6 parts of hydrophobic agent and 1-3 parts of coalescing agent. The formaldehyde-free building paint has the advantages that the waterproof coating has excellent environment protection performance and isnontoxic and odorless, the surface of the paint film does not generate pungent smell during and after construction, influence on human bodies is avoided, and the paint is green and safe and good in elasticity, flexibility and water resistance.

Description

Technical field [0001] The invention relates to the field of coatings, in particular to a formaldehyde-free building coating and a preparation method thereof. Background technique [0002] Coating is a kind of liquid or fixed material that is coated on the surface of an object and forms a thin film under certain conditions to play a protective, decorative and specific role. With the development of economy, coatings are used in industry and agriculture, national defense, scientific research and people. It is more and more widely used in life. With the development of the industry, the variety of coatings is increasing, and the quality and performance of coatings are constantly improving. Coatings can no longer meet people's requirements for protection. Especially in people's daily life, waterproof and moisture-proof are also attracting more and more attention. [0003] With the acceleration of people's life pace and the improvement of their taste in life, health issues have become a...
