Problems solved by technology

[0002] At present, most of the thermal insulation coatings for construction and decoration at home and abroad use thermal insulation materials for thermal insulation, or encapsulate phase change materials to store heat and thermal insulation. Such materials have a solid structure, high density, and a large amount of spraying per unit area. Expensive, single-function, not cost-effective

Abstract

A compound type heat insulation architectural coating and a production method thereof. Self made granular microcapsule insulation particles and porcelain-like insulation emulsion are used as basic materials for the preparation of the coating, and other accessories can also be added to prepare the coating. According to the invention, gas with good heat insulation performance is enwrapped to form empty capsules so as to reduce the heat conductivity coefficient of the coating, thereby achieving the purpose of heat insulation, and therefore the coating has an excellent effect in heat insulation and is favorable for energy saving and consumption reduction; the porcelain-like insulation emulsion and the granular microcapsule insulation particles are mixed and sprayed on the surface of an objectto form a coating, and the coating shows a uniformly convex and stereo structure after dried because the gravity of the emulsion is different from that of the particles, thereby achieving a strong feeling of texture and a wild decorative effect as well as a noise cancelling effect. The compound type heat insulation architectural coating provided in the invention has a simple production process, is convenient for storing, transporting and construction, and is cheap.

Description

technical field [0001] The invention relates to a coating and a production method thereof, in particular to a composite thermal insulation architectural coating and a production method thereof. Background technique [0002] At present, most of the thermal insulation coatings for construction and decoration at home and abroad use thermal insulation materials for thermal insulation, or encapsulate phase change materials to store heat and thermal insulation. Such materials have a solid structure, high density, and a large amount of spraying per unit area. Expensive, single-function, not cost-effective. In the industry, there are few multifunctional composite thermal insulation architectural coatings with thermal insulation and noise reduction functions, good decoration, convenient storage, transportation and construction, and the development of such coatings meets the needs of the market. Contents of the invention [0003] The purpose of the present invention is to solve the...
