Abstract

The invention discloses a building external wall heat preservation coating and a preparation method thereof. The coating is prepared from, by weight, 40-60 parts of silicone acrylic emulsion, 45-55 parts of expanded perlite, 1-5 parts of triethylene glycol monodecyl ether, 1-5 parts of potassium ricinoleate, 4-8 parts of copper(II) dimethyldithiocarbamate and 5-10 parts of starch aluminium octenylsuccinate. The thermal conductivity coefficient of the heat preservation coating is low, the heat preservation performance of the coating is obviously improved, the water resistance, acid and alkali resistance and washing resistance are good, the raw materials are wide in source, and the coating is low in cost, good in pollution resistance, environmentally friendly and free of pollution.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a thermal insulation coating for building exterior walls and a preparation method thereof. Background technique [0002] Coating is a material that can be coated on the surface of an object by different construction techniques to form a solid film with strong adhesion, certain strength and continuity. The film formed in this way is commonly called a coating film, also known as a paint film or a coating. Architectural coatings are a class of coating products mainly used for house decoration. With the development of urbanization and real estate, the application market of architectural coatings is gradually increasing. [0003] In order to save energy and improve the quality of living, thermal insulation coatings, as an important part of building energy conservation, have become a hot topic in current research. However, the thermal insulation performance of building exterior wall ...
