Abstract

The invention provides a composite thermal insulation coating. The composite thermal insulation coating is prepared from, by mass, 20-40 parts of silicone acrylate emulsion, 15-25 parts of titanium dioxide-coated hollow microspheres, 8-12 parts of rutile titanium dioxide, 0.8-1.0 part of mica powder and 3.2-7.2 parts of an auxiliary. According to the composite thermal insulation coating, the hollow microspheres are obtained by adopting a titanium dioxide sol coating mode, titanium dioxide and the hollow microspheres are combined compactly and are not prone to falling, the microspheres are high in strength, white in appearance, high in reflectivity, and the obtained titanium dioxide-coated hollow microspheres both have the thermal reflection function of the titanium dioxide and have the thermal insulation function of the microspheres; the preparation technology is simple, equipment is low in requirement and easy to operate and control, and the production cost is low.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and in particular relates to a preparation method of a composite heat-insulating coating. Background technique [0002] The most important thing for building energy saving is to make the walls, roofs, doors and windows of the building have better heat insulation performance and good airtight performance. Among the many building thermal insulation materials currently on the market, building thermal insulation coatings have been widely accepted and applied because of their advantages such as economy, ease of use and reliable thermal insulation effect. Building thermal insulation coatings are made of synthetic resin emulsion as the base material, water as the dispersion medium, adding functional pigments and fillers (mainly pigments and fillers for sunlight reflection, radiation, and barrier) and additives, and are made through a certain process. For the thermal insulation effect of ...
