Paint and preparation method thereof

Abstract

The invention provides paint and a preparation method thereof and belongs to the technical field of paint preparation. The paint is prepared from raw materials in parts by weight as follows: natural resin, synthesized resin, pigments, filler, a solvent and an additive, wherein the filler is a mixture of diatomite or titanium dioxide with the size smaller than 100 nm, tourmaline and zinc oxide nanopowder, and the additive is a formaldehyde scavenging agent. The method comprises steps as follows: (1) the natural resin and the synthesized resin are mixed with the solvent, and a mixed solution is obtained; (2) the pigments and the filler are added to the mixed solution and stirred with a blender, and a mixture is obtained; (3) the additive is added to the mixture, the mixture is vacuumized and then stirred continuously, and the required paint is obtained. The preparation process of the paint is simple, and the paint has the functions of removing formaldehyde volatilizing from paint and plates and improving the air quality and is low in preparation cost. The paint is prepared from the resin serving as a base material, the pigments and the filler through dispersion and coupling treatment, namely, through mechanical stirring.

Description

[0001] 【Technical field】

[0002] The invention relates to the technical field of paint preparation, in particular to a paint and a preparation method thereof.

[0003] 【Background technique】

[0004] Common traditional paints (oil-based paints) in the market are made of natural resin or synthetic resin as the base material, and then various pigments, various fillers, auxiliary solvents are added and manufactured through mechanical processing. At present, traditional paints have the advantages of chemical resistance, water resistance, tough paint film, and good abrasion resistance. However, some resin molecular chains are rigid, resulting in insufficient flexibility of the paint film; the addition of inorganic pigments and fillers results in insufficient adhesion.

[0005] In recent years, with the development of the invention and application of nanotechnology, people have introduced nanotechnology into the field of coating industry, such as: CN1287143A "High Elastic Nanocoati...
