Abstract

The invention discloses a thermal insulating coating and a preparation method thereof and relates to the technical field of coatings. The coating comprises the following raw materials in parts by weight: 60-80 parts of organosilicone modified styrene-acrylic emulsion, 25-40 parts of modified nano glass fibers, 12-20 parts of carboxymethyl cellulose sodium, 8-14 parts of zirconia, 4-6 parts of pureiron powder, 8-12 parts of a cross-linking agent, 10-18 parts of additives, 3-9 parts of a film-forming agent, 4-10 parts of a fluorocarbon surfactant and 1-5 parts of dimethylhexylamine. The coatinghas very excellent thermal insulating property, heat-shielding performance as well as adhesive property and mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a thermal insulation coating and a preparation method thereof. Background technique [0002] In my country's energy consumption, building energy consumption accounts for about 35% of the national energy consumption. Among building insulation materials, building insulation coatings are more and more popular due to their advantages of convenient use, good heat insulation effect, and economical feasibility. The favor of the coating has broad development prospects. The existing thermal insulation coatings use porous fillers or reflective materials to achieve the purpose of thermal insulation of the coating. The thermal insulation performance is poor, and the bonding between the coating and building materials The disadvantage of low performance. [0003] The Chinese invention patent application with the publication number CN106147472A discloses a thermal insulation coating...
