Heat-insulating water-based paint for color coating of stainless steel and preparation method of heat-insulating water-based paint

Abstract

The invention discloses a heat-insulating water-based paint for color coating of stainless steel and a preparation method of the heat-insulating water-based paint. A formula of the heat-insulating water-based paint comprises the following components in parts by weight: 10 parts of purified water, 15 parts of adhesive, 5 parts of titanium dioxide, 35 parts of an emulsion, 3 parts of an antibacterial pigment, 3 parts of hollow glass beads, 0.2 part of a defoaming agent, 0.6 part of an anti-fouling agent, 3 parts of sericite powder, 2 parts of talcum powder, 3 parts of a cold pigment, 5 parts of an opaque polymer, 0.2 part of a dispersing wetting agent, 0.3 part of a thickening agent and 2 parts of hollow particle microbubbles. According to the method, the proportions of production raw materials are changed, and proper amount of the hollow glass beads and the hollow particle microbubbles are added into the coating, so the paint can play a role in heat insulation; after the paint is sprayed on a stainless steel plate, the paint has heat insulation and heat preservation performance; and the anti-fouling agent is added in the formula of the paint, so decay, fouling and corrosion can be prevented, and the practicability of the paint is improved.

Description

technical field [0001] The invention discloses a heat-insulating water-based coating for stainless steel color coating and a preparation method thereof, belonging to the technical field of stainless steel color coating production. Background technique [0002] The traditional name of paint in China is paint. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated. It is usually based on resin, or oil, or emulsion. Or do not add pigments, fillers, add corresponding additives, and use organic solvents or water to prepare viscous liquids. There are many types of coatings, and water-based coatings are one of them. Any coating that uses water as a solvent or as a dispersion medium , can be called water-based coatings. According to the type of adhesive in the coating, water-based coatings are divided into two categories: natural water-based coatings of natural substances or m...

Problems solved by technology

[0004] When the existing stainless steel color coating is used, the heat insulation performance is poor, and the heat insulation protection of the object cannot be provided under sunlight, and the paint is easy to fall off and corroded during long-term use, which makes the practicability relatively low.
