Problems solved by technology

Children's nature is to scribble on the walls of their homes, which has caused a lot of trouble for parents. The easy-to-clean interior wall paints on the market are difficult to clean stubborn stains such as marker pens and oil-based pens, and the paint film is easily damaged. , so it cannot achieve the purpose of anti-graffiti. In addition, although the anti-graffiti wall coatings on the market cannot scribble on the surface of the paint film, they cannot be used as indoor wall coatings. This is mainly because solvent-based anti-graffiti materials are not environmentally friendly. , especially in recent years, due to the excessive amount of volatile organic compounds such as benzene in wall paint, which can cause various diseases in children

Abstract

The invention discloses a water-based anti-doodling paint and a preparation method thereof. The water-based anti-doodling paint is used for solving the problems of not environmental protection, no doodling and no erasing of the anti-doodling paint. The water-based anti-doodling paint is prepared from the following components in percentage by weight: 0.5-1.5% of dispersant, 0.1-0.3% of defoamer, 0.05-0.15% of wetting agent, 1-3% of coalescing agent, 20-35% of EVA emulsion, 9-29% of fluorosilicon resin, 1-12% of fluorine-containing nanosilicon dioxide dispersion liquid, 0.5-2% of coupling agent and 23-33.5% of pigment filler. The water-based anti-doodling paint is environment-friendly and erasable.

Description

technical field [0001] The invention relates to paint technology and organic macromolecule composite technology, in particular to water-based anti-graffiti paint and a preparation method thereof. Background technique [0002] With the development of the economy, people's requirements for home decoration are also increasing. For the painting of the wall, it is not limited to the smoothness and smoothness of the wall and the color of the paint, but also considers the issues of health, safety and environmental protection. Children's nature is to scribble on the walls of their homes, which has caused a lot of trouble for parents. The easy-to-clean interior wall paints on the market are difficult to clean stubborn stains such as marker pens and oil-based pens, and the paint film is easily damaged. , so it cannot achieve the purpose of anti-graffiti. In addition, although the anti-graffiti wall coatings on the market cannot scribble on the surface of the paint film, they cannot be...
