Abstract

The invention discloses elastic anti-fouling outer wall paint with acid rain resistance. The outer wall paint comprises the following components in percentage by weight: 10 to 20 percent of water, 0.5 to 0.8 percent of acrylic ammonium salt dispersant, 20 to 26 percent of rutile type titanium white powder, 2 to 3 percent of kieselguhr, 8 to 15 percent of superfine barium sulfate, 1 to 2 percent of sericite powder, 40 to 50 percent of self-crosslinked elastic acrylic polymer latex, 3 to 5 percent of opaque covering polymer, 1 to 2 percent of anti-freezing agent, 1 to 2 percent of film-forming aid, 0.5 to 0.8 percent of mold-proof anti-algae agent, 1 to 3 percent of organic silicon waterproof agent and 0.5 to 1.5 percent of polyurethane associated thickener. The paint has the advantages of acid rain resistance, good anti-fouling performance, excellent elasticity, mold injury resistance, good storage stability and capability of repeatedly coating a paint film.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an acid rain-resistant elastic anti-pollution exterior wall paint. Background technique [0002] Wall paint is top paint, which is often called latex paint, and is one of the main decorative materials used for walls. Most of the traditional wall paints are water-based latex paints, which use water as the dispersion medium. Wall paint can be divided into exterior wall paint and interior wall paint according to the different uses of architectural paint. [0003] Exterior wall paint is generally a composition formulated from water, pigments, fillers, film-forming aids, wetting agents, dispersants, thickeners, antifreeze, etc., and has different properties due to its different components. functions and uses. Elastic exterior wall paint is a kind of exterior wall paint widely used in exterior wall insulation projects. Because this type of wall paint has good elasticity, ...
