Thin-layer heat-preserving insulation coating material

Abstract

The invention discloses a thin-layer heat-preserving insulation coating material in the field of a building material. The thin-layer heat-preserving insulation coating material comprises the following ingredients: 25 to 45 parts of hollow glass beads, 10 to 25 parts of titanium dioxide, 3 to 10 parts of a defoaming agent, 5 to 10 parts of a thickening agent, 5 to 10 parts of a dispersing agent, 5 to 10 parts of a curing agent, 30 to 50 parts of acrylic emulsion, 10 to 25 parts of a nano sizing agent, 3 to 10 parts of a flatting agent and 3 to 8 parts of a flame retardant agent. The thin-layer heat-preserving insulation coating material has the beneficial effects that the heat conduction coefficient of a coating film is relatively low, and the comprehensive performance of the coating film is optimum; the heat reflection rate of the coating film can be improved by adding an appropriate nano material; the heat-preserving coating material is good in heat-preserving insulation function and can be smeared in a thin layer; fluorosilicone-modified acrylic emulsion is selected as a film forming matter in the coating material, and the nano material is provided, so that the artificial aging resistance of the coating film can be greatly improved.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a thin-layer thermal insulation coating. Background technique [0002] Building energy consumption accounts for 30% to 40% of human energy consumption. Improving the thermal insulation performance of buildings is an important way to save energy and improve the function of buildings. External wall insulation technology can obviously play a role in protecting the wall and saving energy. In the traditional external thermal insulation system, the finishing coating only has the function of decoration and general waterproofing, and does not have the function of thermal insulation, which has certain limitations for the protection of the whole system. As we all know, when the thermal insulation system is exposed to direct sunlight, due to the large thermal resistance of the polystyrene thermal insulation board, it will be difficult for the heat in the protective layer (plastering m...

Problems solved by technology

In case of sudden heavy rain, the temperature drops sharply, and the temperature change can reach 30-50 °C. The stress caused by the temperature difference can easily cause cracks in the protective layer and the decorative layer, and the temperature of the protective layer and the decorative layer is too high, which will make the The polystyrene board produces irreversible heat shrinkage deformation, which will also cause serious cracking of the protective layer and the decorative layer

Once the surface layer is cracked, it will not be waterproof, and rain or water vapor will enter the insulation layer and adhesive mortar layer along the cracks, causing the bond strength of the insulation board to decrease, and the system will fall off in serious cases
