Abstract

The invention discloses concrete outer wall waterproof heat insulation paint and a preparation method thereof, and relates to the technical field of paint. The paint is prepared from 55 to 65 parts ofacrylate emulsion, 50 to 55 parts of modified phenolic resin, 10 to 15 parts of modified hollow ceramic microspheres, 8 to 11 parts of fly ash-graphene composite powder, 3 to 5 parts of waste glass-iron praseodymium magnetic oxide powder, 3 to 5 parts of osmotic reinforcing agents, 10 to 25 parts of auxiliary agents and 65 to 75 parts of water. The preparation method comprises the steps of preparing liquid material ingredients and the like. The paint has good waterproof and heat insulation performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a waterproof and heat-insulating coating for concrete exterior walls and a preparation method thereof. Background technique [0002] Exterior wall coatings are painted on the exterior walls of buildings. Exterior wall decorations are directly exposed to nature and subjected to wind, rain, and sun exposure. Therefore, the coatings are required to have water resistance, color retention, pollution resistance, aging resistance, and good adhesion. At the same time, it also has the characteristics of good freeze-thaw resistance and low film-forming temperature. There are many exterior wall coating materials and technologies, among which the coatings coated on the surface of concrete exterior walls still have problems such as poor water resistance and thermal insulation performance. Contents of the invention [0003] The object of the present invention is to provide a waterproof and...
