Abstract

The invention belongs to the field of construction materials and discloses a stain-resistant elastic latex paint for an exterior wall and a preparation method of stain-resistant elastic latex paint. The elastic latex paint comprises the following raw materials in parts by weight: 10-20 parts of deionized water, 0.5-1.0 part of a wetting dispersant, 0.2-0.5 part of a defoaming agent, 1-2 parts of propylene glycol, 0.1-0.2 part of a pH adjusting agent, 15-25 parts of titanium dioxide powder, 2-5 parts of mica powder, 5-10 parts of kaolin, 5-10 parts of wollastonite powder, 35-50 parts of a highly elastic acrylic emulsion, 5-15 parts of a modified acrylic emulsion, 5-10 parts of a covering polymer emulsion, 0.1-0.5 part of fungicide, 1-2 parts of a coalescing agent and 0.3-1 part of a thickener. The elastic latex paint has the advantages of high elasticity, high tensile strength, good stain resistance, water resistance and gas permeability, excellent weathering performance, good stability and excellent workability. By adopting the elastic latex paint, the beauty degree of the building is improved and a long-term protection is provided.

Description

[0001] technical field [0002] The invention belongs to the field of building materials and relates to a latex paint, in particular to a stain-resistant elastic latex paint for exterior walls and a preparation method thereof. Background technique [0003] The main function of the exterior wall latex paint is to decorate and protect the building surface, so that the appearance of the building is neat and beautiful, so as to achieve the purpose of beautifying the urban environment, and at the same time, it can protect the exterior wall of the building and prolong its service life. People's pursuit of a healthy and clean ecological living environment is becoming more and more intense, and more and more attention is paid to products with antibacterial functions. The elastic latex paint for exterior walls of the prior art has poor stain resistance and poor antibacterial properties, so it is necessary to develop a high-quality elastic latex paint for exterior walls with strong st...
