Abstract

The invention discloses thermal-insulation coating and a preparation method thereof. The coating is prepared from the following components: light calcium carbonate, modified graphene, polyvinyl acetate, phenolic resin, alkyd resin, sodium tripolyphosphate, fatty alcohol polyoxyethylene ether sodium sulphate, hydroxypropyl methyl cellulose, absolute ethyl alcohol, silicon dioxide, ethyl acetate and water. The preparation method comprises the following steps: adding light calcium carbonate, polyvinyl acetate, phenolic resin and alkyd resin into absolute ethyl alcohol, and uniformly stirring and mixing to obtain mixed liquid I; then, adding sodium tripolyphosphate, fatty alcohol polyoxyethylene ether sodium sulphate and hydroxypropyl methyl cellulose into water, heating and stirring to obtain mixed liquid II; adding the modified graphene into the mixed liquid I, adding ethyl acetate, heating and refluxing under a stirring state to obtain mixed liquid III; and finally adding the mixed liquid II and silicon dioxide into the mixed liquid III, uniformly mixing, and grinding to obtain the thermal-insulation coating. The coating has excellent thermal insulation and wet resistance.

Description

technical field [0001] The invention belongs to the technical field of paint preparation, and in particular relates to a heat-insulating paint and a preparation method thereof. Background technique [0002] Coatings are one of the indispensable materials for the development of the national economy. Due to the many special functions of coatings, there are many varieties of coatings. Architectural coatings have the functions of decoration, protection and habitability improvement. The proportions of various functions vary depending on the purpose of use. The decorative function is to improve the appearance value of a building by beautifying it. It mainly includes the conceptual design of flat color, pattern and gloss and the conceptual design of three-dimensional pattern. However, it must be matched with the shape of the building itself and the size and shape of the base material itself, so that it can be fully utilized. The protection function refers to the function of pro...
