Abstract

The invention discloses a water-based transparent heat-insulating paint used for energy-saving doors and windows. The paint comprises the following components by weight: 50 to 60% of an aqueous base latex, 20 to 30% of aqueous nanometer heat-insulating slurry, 0.5 to 1% of a defoaming agents, 1 to 5% of a thickening agent, 0.5 to 1% of a film forming auxiliary agent and 0.5 to 1% of a leveling agent, with the balance being deionized water, wherein the aqueous base latex is an aqueous acrylic resin emulsion with solid content of 30 to 60 wt% or an aqueous polyurethane resin emulsion with solid content of 30 to 60 wt%, and the aqueous nanometer heat-insulating slurry contains the two functional particles consisting of fluorine-doped tin oxide and aluminum-doped zinc oxide. The invention further discloses a preparation method for the paint. The paint prepared in the invention can be coated on the surface of door and window glass to form a transparent film; and the film can absorb the vast majority of ultraviolet light and obstruct more than 60% of infrared light and has average transmittance of more than 70% in a visible light area.

Description

technical field [0001] The invention relates to a water-based transparent heat-insulating paint for energy-saving doors and windows and a preparation method thereof. The paint is coated on door and window glass to achieve the effect of heat preservation and heat insulation. Background technique [0002] With the rapid development of science and technology and social production, energy and the environment have become two major issues of increasing concern to the whole society. The world's energy demand is growing at 2% per year, and about 30% of this energy is consumed in buildings. Environmentally friendly building energy-saving materials will become the key to solving building insulation and energy saving. In building energy consumption, building heating and air-conditioning consume a considerable proportion, and the energy lost through doors and windows accounts for about half of the entire building’s heating and air-conditioning energy consumption. At the same time, the h...
