Water-based coating for insulating glass and preparation method of water-based coating

Abstract

The invention relates to the technical field of insulating glass, in particular to a water-based coating for insulating glass and a preparation method of the water-based coating. The water-based coating is prepared from the following raw materials: 62-95 parts of water-based acrylic acid emulsion, 3-10 parts of large-particle-size titanium dioxide dispersion slurry, 10-20 parts of nano-porous SiO2, 2.5-10 parts of hollow glass microspheres, 3-8 parts of superfine mica powder and 0.5-2 parts of a functional aid, wherein the particle size of titanium dioxide in the large-particle-size titanium dioxide dispersion slurry is 1-15 mu m; the weight ratio of the nano-porous SiO2 to the hollow glass microspheres is 1:(0.25-1). The water-based coating is applied to the surface of the glass, filled titanium dioxide with large particle size can selectively reflect light in the infrared section and weaken heat radiation transmitted by the glass; due to the mixture of nano-porous SiO2 and hollow glass microspheres with large and small particle sizes, filling in the water-based coating is more compact, heat radiation transmitted by the glass is greatly weakened, and excellent heat preservation and insulation effects are achieved.

Description

technical field [0001] The invention relates to the technical field of insulating glass, in particular to a water-based paint for insulating glass and a preparation method thereof. Background technique [0002] Glass is a material with high transparency, high hardness and airtightness. It is chemically inert in daily life and will not interact with organisms. Therefore, glass has a wide range of uses. The glass used in buildings in the prior art is mainly used to achieve daylighting in a closed environment. However, as a closed material different from the wall, the heat lost through the glass accounts for a large part of the heat loss in the closed space, especially In some cold regions, this heat energy wasted through glass is very large. In order to reduce the heat lost through glass doors, windows and curtain walls, a lot of heat insulation glass has been developed at home and abroad in recent years, such as (1) insulating glass composed of two or more layers of ordinary...

Problems solved by technology

Among them, the insulating glass made of heat-reflective coated glass or low-emissivity coated glass is the mainstream product of energy-saving glass at present. Infrared radiation, but in the winter when heating is required, it is obviously inappropriate to block outdoor heat from entering the room, and it will affect the transmittance of visible light
