Abstract

The invention relates to alga resistant exterior wall cement paint which comprises the compositions of water, a disperser, a bactericide, an antifoaming agent, a wetting agent, titanium dioxide, 800-mesh coarse whiting, barium sulphate, hydroxyethyl cellulose, 296DS latex, propylene glycol, mouldproof algaecide, an antifoaming agent, a thickener, a film forming auxiliary agent, and 28 percent strong aqua. The cement paint is characterized in superstrong resistance to mildew and alga, and environmental protection without pollution. The cement paint can form a firm paint film with a superstrong adhesion force to basis materials after being painted.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an algae-proof exterior wall cement paint. Background technique [0002] The development direction of architectural coatings is high decoration, strong stain resistance, high durability, resource saving, energy saving, pollution-free, pollution-free, environmentally friendly, and in line with the requirements of sustainable development. From the perspective of decoration and stain resistance and durability, solvent-based coatings are easier to meet the requirements, such as solvent-based acrylic coatings, especially the newly developed solvent-based fluorocarbon coatings, whose stain resistance and anti-aging properties have reached a very high level. , but its solvent consumption is large, its toxicity is high, the coating has poor air permeability, and it is easy to peel off; water-based coatings such as water-based acrylic, water-based epoxy, water-based polyester and water-based silic...
