Abstract

The invention provides a waterborne glass thermal insulation coating and a preparation method thereof. The waterborne glass thermal insulation coating includes the following components in parts by weight: 70-90 parts of epoxy-modified organic silicone resin, 10-20 parts of pure acrylic emulsion, 5-15 parts of nano aerogel, 5-15 parts of thermal insulation filler, 1-3 parts of a wetting dispersant,0.5-1 part of a mildew preventive, 4-8 parts of a thickener, 1-3 parts of a defoamer, 6-12 parts of a coalescing agent and 40-60 parts of deionized water, wherein the thermal insulation filler is modified potassium hexatitanate whiskers mainly prepared from expanded perlite, indium trichloride and zirconium oxychloride. The coating not only has higher reflectivity and emissivity, good thermal insulation, and low heat conductivity coefficient, and but also can be used for indoor thermal insulation.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based glass heat-insulating coating and a preparation method thereof. Background technique [0002] Water-based glass thermal insulation coating is a new type of functional architectural coating that has been applied and paid attention to in recent years. In the hot summer and warm winter and hot summer and cold winter climate regions where the summer temperature is too high in our country, the coating not only has the decorative effect of ordinary exterior wall coatings, but also can reflect solar radiant heat to reduce the surface temperature of the coating film, and reduce the damage caused by summer coating. A series of problems caused by the high surface temperature of the membrane. Although water-based glass heat-insulating coatings have been studied a lot, there are still many problems in practical applications, such as: unstable performance, although...
