Abstract

The invention belongs to the technical field of glass material preparation, and particularly relates to a preparation method of light-transmitting heat-insulating glass. According to the method, skimmilk and silicon-titanium composite rubber powder are mixed, dispersed, coated, packaged with a polytetrafluoroethylene plate and air-dried to obtain the light-transmitting heat-insulating glass, theheat-insulating glass takes PMMA organic glass as matrix glass, and the heat-insulating effect is achieved through a hydroxyapatite aerogel layer on the surface; the silicon-titanium coated hydroxyapatite aerogel is aerogel compositely coated with silicon dioxide and titanium dioxide and has high strength, the skim milk is oxidized through sodium hypochlorite and then subjected to hydroxyl modification, the adhesiveness between aerogel microspheres is improved, the induced dipole moment is reduced through zinc tin oxide between the aerogel and the glass, and the visible light transmittance isimproved; after the current-carrying light-transmitting glue solution is cured, a layered zinc tin oxide film can be formed, so that the sensitivity of the light-transmitting heat-insulating glass tovisible light is improved, near-infrared light is absorbed, the light transmittance is improved, the heat-insulating property is improved, and the light-transmitting heat-insulating glass has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of glass material preparation, and in particular relates to a method for preparing light-transmitting heat-insulating glass. Background technique [0002] Insulating glass is a kind of performance glass, they do not significantly absorb visible light, but absorb a lot of heat-generating near-infrared light. At present, the high heat insulation performance of energy-saving glass is mainly reflected in the performance of blocking infrared and ultraviolet rays in solar radiation. If the glass cannot effectively block the heat of outdoor sunlight from entering the room, the thermal radiation of the heated glass will increase the temperature in the space, thereby reducing the comfort. At present, commercially available insulating glass absorbs short-wave radiation in sunlight, which makes the transmittance of visible light very low, thereby affecting the light transmittance of the glass. And it is greatly affec...
