Abstract

The invention discloses a waterproof and heat insulation coating and a preparation method thereof, and relates to the technical field of coatings. The coating comprises raw materials in parts by weight as follows: 45-55 parts of starch modified acrylic emulsion, 12-16 parts of modified magnesium stearate powder, 4-8 parts of polyester fiber, 5-8 parts of aluminium silicate cellucotton, 10-16 partsof a thickener, 6-12 parts of sodium dodecyl benzene sulfate, 3-7 parts of sodium abietate, 4-8 parts of a polyoxyethylene-polyoxypropylene copolymer, 8-12 parts of a silicone defoamer and 10-16 parts of a silane coupling agent. The preparation method of the coating comprises the step of mixing and stirring the materials. The coating has quite excellent waterproof and heat insulation properties and has high adhesion to building materials.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a waterproof and thermal insulation coating and a preparation method thereof. Background technique [0002] At present, coatings are generally applied on building materials to avoid oxidation of materials and improve the aesthetics of materials. In the prior art, most coatings are generally poor in waterproof performance and thermal insulation performance, and their adhesion is average. After being washed away by rain, sunlight, etc. over time, the paint is easy to fall off, resulting in unsightly buildings, and cannot protect building materials, resulting in shortened service life. [0003] The Chinese invention patent application with the publication number CN102719155A discloses a polymer waterproof coating and a preparation method thereof, which is made of powder and liquid in a weight ratio of 1-5:1; the powder is prepared in parts by weight The number includes...
