Anti-stain acid and alkali resistance coating and preparation method thereof

Abstract

The invention discloses an anti-stain acid and alkali resistance coating and a preparation method thereof. The coating comprises 5-35 parts of basalt fiber powder, 45-75 parts of acrylic resin, 3-5 parts of chlorinated paraffin, 3-5 parts of titanium dioxide, 3-5 parts of talcum powder, 5-8 parts of ultra-fine aluminum silicate, 5-7 parts of diatomite, 0.2-0.4 part of dispersing agents, 2-10 parts of anti-mildew agents, 2-10 parts of defoaming agents, 2-3 parts of thickening agents and 3-5 parts of other auxiliaries. The coating has high weather resistance, excellent adhesiveness, high stain resistance and acid and alkali resistance and good chemical stability, can be constructed on a humid surface, and can be directly used as priming paint and second coat. Various methods such as brush coating, spray coating and dip-coating are used for construction, drying is rapid, and a paint film is high in mechanical strength and strong in adhesive force, can effectively stop corrosive media from permeating into a coating layer and can be widely used for places such as buildings, trains, high-speed trains, ships and large equipment with high anti-corrosion requirements.

Description

technical field [0001] The invention relates to a paint that provides protective properties for surfaces that require it, in particular to an anti-fouling, acid- and alkali-resistant paint. Background technique [0002] In recent years, with the development of industry, environmental pollution has become more serious. Certain buildings, trains, high-speed rail, ships, and large equipment are exposed to the outside due to the acid-base environment, which is easy to cause external aging and corrosion. At present, solvent-based architectural coatings are restricted in architectural coatings because they release toxic solvents during the curing process and do not meet environmental protection requirements. However, the polymer film-forming materials of solvent-based coatings have strong aging resistance, good adhesion, smooth coating, and Stain resistance, abrasion resistance, acid and alkali resistance, water resistance, etc. are superior to general water-based coatings, and ar...

Problems solved by technology

At present, solvent-based architectural coatings are restricted in architectural coatings because they release toxic solvents during the curing process and do not meet environmental protection requirements. However, the polymer film-forming materials of solvent-based coatings have strong aging resistance, good adhesion, smooth coating, and Stain resistance, abrasion resistance, acid and alkali resistance, water resistance, etc. are superior to general water-based coatings, and are still used in exterior wall decoration of high-rise buildings, trains, high-speed rails, ships, and large equipment.
