Bamboo charcoal odor-cleaning and formaldehyde-removing emulsion paint and preparation method thereof

Abstract

The invention provides a bamboo charcoal odor-cleaning and formaldehyde-removing emulsion paint. The emulsion paint comprises the following components in parts by weight: 100-400 parts of waterborne resin, 1-5 parts of defoaming agent, 1-5 parts of preservative, 1-10 parts of dispersant, 100-300 parts of pigment, 100-400 parts of filler, 1-10 parts of nanometer thickener, 1-10 parts of flatting agent, 5-20 parts of nanometer inorganic anionic formaldehyde-removing additive, 40-100 parts of nanometer polymer hollow microspheres, 10-20 parts of bamboo vinegar and 0-350 parts of water. The bamboo charcoal odor-cleaning and formaldehyde-removing emulsion paint can be coated on the wall and wood; the paint film is characterized by light odor, low volatile organic compound (VOC), good hiding power and adhesion, washing and wiping resistance and the like; the harmful substances such as formaldehyde and benzene can be removed; the cost is low, the construction property is good, the environmental friend is good; and the emulsion paint is a product which combines decorative function, functionality and environmental friend together perfectly.

Description

technical field [0001] The invention relates to the field of functional environmental protection coatings, in particular to a bamboo charcoal deodorizing and formaldehyde-removing latex paint and a preparation method thereof. Background technique [0002] Emulsion paint has the characteristics of convenient construction and various colors. It occupies a dominant position in domestic interior wall decoration, and its market share exceeds 80%. [0003] In order to achieve better film-forming performance, the emulsions used in common latex paints on the market will add some film-forming aids and antifreeze agents. In the process of emulsion synthesis, a small amount of free monomers will remain, which are all volatile organic compounds (VOC). When the VOC in the room reaches a certain concentration, it will cause symptoms such as headache, nausea, vomiting, fatigue, etc., and even convulsions in severe cases. coma, damage to the liver, kidneys, brain and nervous system, causin...

AI Technical Summary

Problems solved by technology

And there are applications in cosmetics, laundry detergent, etc., but there is no literature about the application of bamboo vinegar in coatings at present

[0008] There are also many manufacturers who have tried to use bamboo charcoal in latex paint, but they have not been able to solve the problem of dispersion of bamboo charcoal powder in latex paint, and cannot play the porous adsorption effect of bamboo charcoal.

However, the use of bamboo charcoal liquid in latex paint is difficult to control the volatilization of bamboo vinegar liquid. As the latex paint dries, the bamboo charcoal liquid will quickly evaporate from the latex paint and lose its effect.
