Thermal insulation antibacterial coating for external wall

Abstract

The invention discloses a thermal insulation antibacterial coating for an external wall, which is prepared by stirring the following raw materials by weight ratio: 45 to 60 parts of acrylic ester resin, 15 to 25 parts of polyvinyl alcohol, 44 parts of nanometer titanium dioxide, 25 parts of nanometer copper powder, 6 parts of leveling agent, 15 parts of nanometer silicon dioxide, 6 to 9 parts of silica acid aluminum powder, 12 to 15 parts of ethylene glycol, 10 parts of nanometer silicon dioxide, 8 parts of mildew-proof agent, 5 parts of calcium carbonate, 6 parts of cementing agent, 3 parts of antifoaming agent, 3 parts of modifier and 35 to 45 parts of water. The product has low heat conductivity and has the characteristics of good water-proof heat preservation, no-forming, no-cracking, good adhesive force, contamination resistance, cracking resistance and effectively mould removal.

Description

technical field [0001] The invention relates to an external wall thermal insulation and antibacterial coating, which belongs to the technical field of chemical coatings. technical background [0002] The existing building exterior wall coatings are mainly solvent-based coatings and water-based coatings, which are applied to the exterior surface of walls to achieve decorative effects and prevent erosion by water, air, microorganisms and corrosive substances. materials, additives and fillers. Existing coatings for exterior walls of buildings have poor adhesion, weak weather resistance and water resistance, and cracks will occur after a long time of use, thereby affecting the thermal insulation performance of the wall. harm, and destroy the beauty of the wall. Now people's requirements for building materials are further improved, so they cannot meet market requirements. Contents of the invention [0003] The object of the present invention is to provide an external wall th...
