Problems solved by technology

[0003] After the construction of latex paint is completed and the volatiles are volatilized, the paint film remaining on the surface of the building is the effective component to protect the wall, which is usually measured by volume solid content; most interior wall latex paints on the market currently have volume solid content measurement Low, weak adhesion, poor water and weather resistance, long-term exposure to the air is prone to problems such as peeling, cracking, discoloration, and powder removal; it also contains formaldehyde or benzene solvents that pollute the environment and have radiation hazards to human health; Moreover, the preparation method of the existing interior wall latex paint has high cost, complicated process, and problems such as harmful substances that pollute the environment.

Abstract

The invention relates to a preparation method of environment-friendly anti-radiation internal wall latex paint. The preparation method is simple in process, low in production cost, safe, environmentally friendly and suitable for industrial production; by taking an organic silicone modified acrylate emulsion as the main raw material, the latex paint has good high-low temperature resistance, water tolerance and weather resistance and low surface energy; by virtue of a synergistic effect of modified hollow glass beads, jade powder and a radix polygonati officinalis-grape leaf mixed extracting solution, the latex paint has good radiation resistance, reflective heat insulation property and ultraviolet absorption capacity; an ionic emulsifier is embedded into a non-ionic emulsifier so as to increase the distance of reactive emulsifier ionic bonds on the surfaces of latex particles, and the electrostatic tension of the surfaces of the latex particles is decreased by virtue of the non-ionic emulsifier, so that the distribution range is enlarged, and the latex paint has relatively high stability and good surface tension; by utilizing shell powder, the latex paint has a fine texture, a pain film is replenished, and the latex paint is unlikely to precipitate, has excellent brushing property and is capable of adsorbing substances such as formaldehyde and metal ions due to the porosity; and by taking deionized water as a solvent, the latex paint is safe, environmentally friendly, high in volume solid content, low in VOC, strong in adhesive force and excellent in water tolerance, and the thickness of the paint film can be increased.

Description

technical field [0001] The invention relates to the technical field of exterior wall latex paint, in particular to a preparation method of an environment-friendly radiation-proof interior wall latex paint. Background technique [0002] Interior wall latex paint is a kind of paint with polymer emulsion as film former, and it is a kind of water-based paint formulated with synthetic resin emulsion as raw material by adding pigments, fillers and various additives. The main function of interior wall latex paint is to decorate and protect the building surface, so that the interior surface of the building is neat and beautiful, so as to achieve the purpose of beautifying the interior of the building, and at the same time, it can protect the interior wall of the building and prolong its service life. [0003] After the construction of latex paint is completed and the volatiles are volatilized, the paint film remaining on the surface of the building is the effective component to prot...
