Abstract

The invention relates to a thermal insulation coating applied to building exterior walls. A functional filler composed of pulverized coal ash zeolite and infrared radiation powder is added into the thermal insulation coating to reduce the heat conductivity coefficient of the thermal insulation coating and improve the emissivity of the thermal insulation coating to infrared light, and modified activated carbon is added into the thermal insulation coating to improve the absorption efficiency of the thermal insulation coating to peculiar smells. The thermal insulation coating prepared from the raw materials has a low heat conduction coefficient, can effectively block heat exchange on two sides of the coating, and has high emissivity to infrared light, namely, has the characteristic of low absorption to infrared light radiation, so that the thermal insulation coating has a good thermal insulation effect; due to the fact that the modified activated carbon component is added into the thermalinsulation coating, when the thermal insulation coating is applied to the building, exterior walls, good thermal insulation effect are achieved; and peculiar smells can be rapidly dissipated after coating, so the thermal insulation coating is quite friendly to the natural environment.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a thermal insulation coating applied to exterior walls of buildings. Background technique [0002] With global warming, people are paying more and more attention to protecting the environment to slow down the rise in global temperature. Applying a layer of thermal insulation paint on the exterior wall of a building can reflect the heat of the outer layer of the paint and block the heat exchange on both sides of the paint , can effectively reduce the temperature of the outer surface of the building and further reduce the load of the air conditioner, and has a good effect of energy saving and environmental protection. Traditional heat-insulating coatings add hollow glass microspheres to the fluorocarbon emulsion. Although the hollow glass microspheres can reduce the thermal conductivity of the coating, the hollow glass microspheres tend to absorb infrared radiation. Therefore, alt...
