Environment-friendly latex paint used for interior wall and preparation method thereof

Abstract

The invention discloses environment-friendly latex paint used for an interior wall. The environment-friendly latex paint is prepared from the following raw materials: epoxy resin, acrylic resin, castor oil, dimethyl silicone oil, sodium alginate, polyoxyethylene aliphatic ether sodium sulfate, mica powder, carboxymethylated chitosan, zinc sulfate, 4-methyl-4'-vinyl benzophenone, 2,2,6,6-tetra-methylpiperidine benzoate, a curing agent, ethanol and water. A preparation method comprises the following steps: preparing resin mixed liquor, mixing in the castor oil, dimethyl silicone oil, 4-methyl-4'-vinyl benzophenone and 2,2,6,6-tetra-methylpiperidine benzoate, preparing an aqueous solution, mixing in the aqueous solution, and dispersing the mica powder and the curing agent. The latex paint disclosed by the invention has the advantages that raw materials are cheap and available, environmental friendliness, scrubbing property, good antibacterial effect, appropriate workability, good stability, difficulty in ageing and direct brushing are realized, and the preparation method provided by the invention is low in requirement on equipment and reasonable and simple in operation, so that industrial production can be carried out.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an environmentally friendly latex paint for interior walls and a preparation method thereof. Background technique [0002] Latex paint is a common name for latex paint, which was born in the middle and late seventies of the 20th century. Latex paint is a water-dispersible paint. It is based on synthetic resin emulsion, and the filler is refined by adding various additives after grinding and dispersing. With the improvement of people's living standards, latex paints with superior performance are usually used for wall painting when decorating. On the one hand, the amount of organic solvents in latex paints is less or even non-existent, which is harmful to the environment and occupants. It is safe and environmentally friendly. On the other hand, latex paint has good water resistance and is not easy to absorb water and drop powder. [0003] In the process of home decorat...

AI Technical Summary

Problems solved by technology

[0003] In the process of home decoration, latex paint is usually painted on the outermost layer of the wall. When using latex paint, it needs to be blended with water, and then painted after mixing evenly. The amount of water will directly affect the brushing performance of latex paint. If it is too thick, the coating will not be smooth; if it is too thin, it will cause flow and fall, which will bring difficulties to the construction.

Moreover, after long-term exposure to sunlight, latex paint will appear discolored and faded, which will affect the decorative effect.

In addition, after the latex paint is painted on the wall for a period of time, oil and dust will adhere to the surface of the latex paint, and sometimes children will paint on the wall, which will not only affect the beauty of the wall, but also cause the reproduction of bacteria , while the existing scrubable latex paints usually have a high cost, and the scrubbing effect and antibacterial effect are poor
