Anti-corrosive construction coating

Abstract

An antisepsis building coating comprises base material, auxiliary and filler and is characterized by comprising antibacterial agent, wherein, the base material comprises polyvinyl alcohol, bisphenol A epoxide resin, zinc silicate powder and oyster shell whiting, the auxiliary comprises fluoresecent brightening agent and antifoaming agent, the filler is calcium carbonate and the antibacterial agent is calcium sulphate crystal whisker artificially growing. By virtue of methyl silica high polymer formed after the reaction between heated silicate and organosilicone, the coating can form the binding of chemical bonds when being coated on the rigid surface of a concrete wall, with the fastness being far superior to that of the physical covering of a conventional coating; in the coating, the calcium sulphate crystal whisker artificially growing is also adopted as the antibacterial agent, therefore, the coating has good effect on inhibiting and killing bacteria, fungus and mycete, contains no formaldehyde as well as benzene, does not harm human body, is low in cost and is characterized by good waterproof performance, no bubbling and cracking, no powder drop and good adhesive force.

Description

Technical field [0001] The invention relates to a coating, in particular to an anti-corrosion architectural coating, which belongs to the category of building materials. Background technique [0002] Existing architectural anti-corrosion coatings are mainly solvent-based coatings and water-based coatings, which are applied to the interior and exterior surfaces of walls to achieve decorative effects and prevent erosion by water, air, microorganisms and various corrosive substances. It consists of base materials, additives and fillers. At present, building anti-corrosion coatings are all made of organic synthetic resins. The surface of the painted wall is only a simple physical covering. It mainly depends on the good waterproof performance of the coating film itself to prolong the anti-corrosion life. Once the waterproof function of the coating film is lost, the anti-corrosion coating will lose its effect. . Contents of the invention [0003] The purpose of the present inv...

At present, building anti-corrosion coatings are all made of organic synthetic resins. The surface of the painted wall is only a simple physical covering. It mainly depends on the good waterproof performance of the coating film itself to prolong the anti-corrosion life. Once the waterproof function of the coating film is lost, the anti-corrosion coating will lose its effect.
