Thermal insulation water-based paint capable of being constructed at low temperature and preparation method thereof

Abstract

The invention relates to the technical field of water-based paint, in particular to heat-preservation water-based paint capable of being constructed at low temperature and a preparation method of the heat-preservation water-based paint. The heat-preservation water-based paint is prepared from the following raw materials in percentage by weight: 0.2 to 0.6 percent of dispersing agent, 0.1 to 0.4 percent of hydroxyethyl cellulose, 0.1 to 0.4 percent of defoaming agent, 0.2 to 0.5 percent of wetting leveling agent, 1 to 4 percent of anti-freezing agent, 0.8 to 2 percent of coalescing agent, 14 to 18 percent of titanium dioxide, 0.4 to 1.2 percent of fumed silica, 0.7 to 1.7 percent of sericite, 4 to 7 percent of nano coated ceramic microbeads, 1.5 to 6 percent of expanded perlite, 7 to 13 percent of floating beads, 6 to 12 percent of aerogel, 0.3 to 0.7 percent of thickening agent, 0.05 to 0.25 percent of mildew preventive and the balance of water. The coating is prepared from the following components in percentage by weight: 0.05-0.25% of a light stabilizer, 0.2-0.6% of an ultraviolet light absorber, 1.5-4% of a silane coupling agent, 9-14% of deionized water and the balance of hydroxyl acrylic emulsion. The thermal-insulation water-based paint has the advantage that the thermal-insulation water-based paint can be constructed at a low temperature.

Description

technical field [0001] The present application relates to the technical field of water-based coatings, in particular to a thermal insulation water-based coating that can be applied at low temperature and a preparation method thereof. Background technique [0002] In some special fields and environmental conditions, it is necessary to insulate the internal temperature of the packaging structure to reduce the external diffusion of internal temperature. The traditional method is to use thermal insulation rock wool to solve the problem. However, due to the consideration of fire safety, rock wool has been gradually eliminated. The existing thermal insulation method is to apply thermal insulation paint on the substrate. Among them, thermal insulation water-based coating is a new type of thermal insulation material, which achieves thermal insulation through low thermal conductivity and high thermal resistance. [0003] Existing thermal insulation water-based coatings generally inc...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that the traditional thermal insulation water-based coatings are generally applied at a temperature above 5°C, which causes the problem that some northern regions are difficult to apply when the temperature is low
