Abstract

The invention provides an external wall paint and a preparation method thereof. The paint comprises the following components in parts by weight: 12-30 parts of epoxy resin, 60-70 parts of isopropanol, 3-8 parts of polyacrylamide, 0.1-0.6 part of potassium hydroxide, 30-55 parts of ethanol, 80-120 parts of water, 110-160 parts of titanium white, 1-8 parts of mica powder, 1-7 parts of diethylene glycol butyl ether, 0.2-0.9 part of nano silicon dioxide, 2-11 parts of polyvinyl alcohol, 1-7 parts of kaolin and 5-15 parts of vitrified microbead. The preparation method comprises the following steps: mixing the epoxy resin, isopropanol, polyacrylamide, potassium hydroxide, ethanol and water, stirring uniformly, adding the rest components, stirring uniformly, filtering and standing. The outer wall paint has the advantages of hard paint film, high impact resistance, higher weather resistance and higher abrasion resistance. The paint film has very high stability and density, and thus, has the advantages of high adhesion and no bubble or crack, and is compact and uniform.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an exterior wall paint and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's living standards and the continuous development of society, people have paid more and more attention to the choice of architectural decorative coatings. The simpler the construction requirements for coatings, the better. Especially for exterior wall coatings, it has not only stayed The most basic protective umbrella for the substrate puts forward higher requirements for the decorative effect of the coating. The exterior wall coating requires water resistance, self-cleaning properties, and the paint film must be hard and smooth. At present, there are three types of building energy-saving thermal insulation: roof thermal insulation, external wall thermal insulation and internal wall thermal insulation, which are mainly compl...
