Heat insulation exterior wall coating

Abstract

The invention discloses a heat insulation exterior wall coating, and belongs to the technical field of coatings. The heat insulation exterior wall coating comprises, by weight, 30-40 parts of a pure styrene acrylic emulsion, 5-10 parts of ferric oxide, 5-10 parts of ferrous oxide, 10-20 parts of talcum powder, 10-20 parts of heavy calcium carbonate, 30-40 parts of deionized water, 10-20 parts of Tween-80, 1-5 parts of an anti-ultraviolet additive, 1-5 parts of hydroxyethyl cellulose, 1-5 parts of magnesium aluminum silicate, 1-5 parts of nanometer zinc oxide, 1-3 parts of nano-flake aluminum powder and 1-3 parts of nano-flake zinc powder. The heat insulation performance of the exterior wall coating is enhanced by using the nonionic surfactant Tween-80 through using the anti-ultraviolet additive and nanometer additives under the cooperation of hydroxyethyl cellulose and magnesium aluminum silicate, and the exterior wall coating also has the advantages of good ultraviolet resistance, good ageing resistance, good weatherability, good chemical corrosion resistance, good scrubbing resistance, improved heat insulation performance, economy and practicality.

Description

Technical field [0001] The invention is a technology field of coatings, especially a kind of insulation exterior wall coatings. Background technique [0002] The coating is a general term that can form a type of liquid or solid material that can form a solid coating film with a solid coating film with protection, decoration or special performance (such as insulation, anticorrosion, logo, etc.) on the surface of the object, including oily paint, water -based paint and powder coatings.As one of the main materials of home decoration and urban greening, coatings occupy a large proportion of modern architectural decoration.With the continuous improvement of people's production and living standards, people's requirements for coating decoration performance and safety performance are getting higher and higher. [0003] With the continuous improvement of people's living standards and the continuous changes in the general warmth of the atmospheric environment, people's heat resistance to s...
