Abstract

The invention discloses an anti-ultraviolet exterior wall coating and a preparation method thereof, and relates to the technical field of exterior wall coatings. The anti-ultraviolet exterior wall coating is prepared from 30 to 40 percent of a component A and 60 to 70 percent of a component B, wherein the component A is prepared from the following raw materials in parts by weight: 80 to 90 parts of EVA (ethylene-vinyl acetate) emulsion, 30 to 60 parts of nano TiO2, 20 to 30 parts of a filler, 10 to 15 parts of a compound adhesive, 2 to 10 parts of an ultraviolet light absorber, 2 to 8 parts of an assistant and 50 to 60 parts of deionized water; the component B is prepared from the following raw materials in parts by weight: 80 to 90 parts of styrene-acrylic emulsion, 30 to 60 parts of waste glass praseodymium and iron magnetic oxide composite powder, 20 to 30 parts of white Portland cement, 2 to 10 parts of coloring pigment and 30 to 60 parts of deionized water. According to the anti-ultraviolet exterior wall coating disclosed by the invention, an anti-ultraviolet material is added on the basis of waterproof property, so that ultraviolet rays can be effectively absorbed; the anti-ultraviolet exterior wall coating has the advantages of being relatively high in heat dissipating effect and weather fastness, safe and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of exterior wall coatings, in particular to an anti-ultraviolet exterior wall coating and a preparation method thereof. Background technique [0002] With the continuous development of the construction field, the absorption range of concrete to the spectrum is large, the heat storage is large, and the wall surface heats up quickly and lasts for a long time; especially in the south, the temperature in summer is above 30°C for a long time, which leads to The room heats up. Therefore, in order to reduce the indoor temperature and improve the comfort of the human body, people have to use fans, air conditioners and other equipment to reduce the indoor temperature, which consumes a lot of electric energy. out of place. It is particularly important to solve the heat insulation problem of the building wall. [0003] Heat dissipation paint is a special paint that improves the heat dissipation efficiency of the sur...
