Abstract

The invention relates to the field of coating, in particular to building external wall theat-insulation coating and a preparation method thereof. Raw materials comprise 80-120 parts of pure acrylic emulsion, 20-40 parts of heat reflection powder, 40-60 parts of titanium dioxide, 20-25 parts of mica powder, 5-10 parts of wollastonite, 5-10 parts of strontium carbonate, 4-8 parts of propylene glycol, 4-8 parts of a coalescing agent, 0.3-0.5 part of a defoaming agent, 2-4 parts of a thickener, 2-3 parts of a dispersion agent and 0.4-0.6 part of a wetting agent. The titanium dioxide, the mica powder, the wollastonite and the strontium carbonate have excellent performance of shielding ultraviolet ray, infrared ray and the like, reflect much, absorb little heat, and effectively block heat transmission, so that the coating has an excellent reflective insulation effect, and has good performance of weather resistance, corrosion resistance, freezing resistance and the like.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a thermal insulation coating for building exterior walls and a preparation method thereof. Background technique [0002] Driven by real estate, automobiles and ships, my country's coatings industry is growing day by day. As one of the important categories, architectural coatings have also achieved rapid development. Architectural coatings have the functions of decoration, protection and habitability improvement. Compared with decoration materials such as stone and ceramic tiles, they have obvious advantages in terms of energy consumption and cost. Therefore, in the field of interior and exterior wall decoration of buildings, the popularity of architectural coatings is gradually increasing. improve. The past 10 years have been called the "golden 10 years" of the real estate industry, and the paint industry has also taken the opportunity to achieve rapid development. At present, my countr...
