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: 35 to 40 parts of acrylate resin, 15 to 25 parts of polyvinyl alcohol, 10 parts of hollow glass microsphere, 10 to 15 parts of titanium dioxide, 6 parts of flatting agent, 15 parts of nanometer silicon dioxide, 25 to 30 parts of cement, 6 to 9 parts of silica acid aluminum powder, 12 to 15 parts of ethylene glycol, 5 parts of polyurethane thickening agent, 10 parts of nanometer silicon dioxide, 3 parts of antifoaming agent, 3 parts of modifier, 35 to 45 parts of water and 4 parts of mildew-proof agent. The product has low heat conductivity and has the characteristics of good water-proof heat preservation, no-forming, no-cracking and good adhesive force.

Description

technical field [0001] The invention relates to an exterior wall thermal insulation 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. 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 exterior wall thermal insulation coating that can effectively maintain the in...
