Abstract

The invention relates to a coating, and specifically provides a heat-insulation energy-saving coating. The coating comprises a methoxy xpolyethylene glycol methacrylate-styrol copolymer, an acrylic acid emulsion, a polyacrylate emulsion, a nanometer mixture and the like. According to the heat-insulation energy-saving coating provided by the invention, a formula that the methoxy xpolyethylene glycol methacrylate-styrol copolymer is combined with a nanometer inorganic matter is adopted, so that the strength performance and the ageing resistance of the coating are improved, a coating layer formed by the coating is resistant to scrubbing and ultraviolet, the ageing resistance and the pulverization resistance are improved, and the service life of the coating layer is prolonged.

Description

technical field [0001] The invention relates to a coating, in particular to a thermal insulation and energy saving coating. Background technique [0002] Building energy conservation is one of the key points of my country's energy conservation work, and external wall insulation has become the main product of building energy conservation. Applying it to the surface of a building can reduce its internal temperature, and it can also make the internal heat of the building difficult to dissipate quickly. Applying a layer of thermal insulation coating on the external wall or roof of the building can effectively control the change of indoor and outdoor temperature and play a role To the role of thermal insulation. The commonly used exterior wall coatings are not strong in mechanical properties, not resistant to washing, easy to powder and aging, which shortens the service life of the coating. Contents of the invention [0003] In view of the above technical problems, the presen...
