Ultra-thin smooth-type heat-insulation coating

Abstract

The invention discloses an ultra-thin smooth-type heat-insulation coating and belongs to the technical field of building external wall coating. The heat-insulation coating is prepared from the following components in parts by weight: 18-21 parts of deionized water, 0.2-0.3 part of cellulose, 1 part of a dispersant, 0.1-0.15 part of a surfactant, 0.1-0.2 part of a regulator, 0.4-0.6 part of a defoaming agent, 2 parts of ethylene glycol, 1.5-2 parts of a coalescing agent, 20-25 parts of titanium dioxide powder, 32-35 parts of emulsion, 0.5-1.2 parts of a thickener, 0.2 part of an anti-corrosion agent, 0.5 part of a mildew preventive and 10-15 parts of a heat-insulation high-molecular polymer, wherein the heat-insulation high-molecular polymer is an SOLARPROOF SP-105 reflective heat-insulation polymer. The production process of the heat-insulation coating is simple and feasible, the heat-insulation coating has super-efficient heat reflectivity, the surface of the coating film is smooth, not rough, and the coating film has a high dirt resistance rate, excellent weather resistance and high storage stability.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an ultra-thin and smooth heat-insulating coating for exterior walls of buildings. Background technique [0002] Energy saving and consumption reduction, improving economic benefits are important conditions for the sustainable development of my country's economy. After the 1970s, the world's climate became warmer, and the earth's energy became increasingly tense. In recent years, with the rapid development of the economy and the continuous advancement of urbanization, the urban population is concentrated and the heat is not easy to spread, so that the temperature in the city is 3-5 ℃ higher than that in the suburbs, which is called the heat island effect. At present, building energy consumption accounts for about 30 shares of the total energy consumption of the whole society, of which the energy consumption of heating and air conditioning accounts for 20 shares. With my country...

AI Technical Summary

Problems solved by technology

Among them, in terms of building heat insulation coatings, the existing technology generally achieves the purpose of heat insulation by increasing the reflectivity of the coating or heat radiation. This heat insulation material is generally a hollow material or a far-infrared radiation ceramic powder. This material is easy to float around during the production and feeding process, polluting the environment

In addition, the particle size of the hollow heat insulation material is widely distributed in the range of 10-180 μm, which is larger than the thickness of the dry film of the coating, so it will protrude after the dry film, resulting in a rough surface, making the coating film dirty, the heat insulation effect is not long-lasting, and it is easy to cause moisture Wait for the external force to enter the rough part, and then destroy the coating film structure

In addition, the hollow insulation material itself is smooth and has poor adhesion, resulting in significantly poor adhesion between the coating film and the material, so the whole piece is easy to fall off
