Heat-insulating glass with ultraviolet-proof coating

Abstract

The invention relates to heat-insulating glass with an ultraviolet-proof coating. The heat-insulating glass comprises a glass substrate, wherein the ultraviolet-proof coating and a heat insulating layer are separately arranged on two surfaces of the glass substrate; the ultraviolet-proof coating is prepared from the following ingredients in percentage by weight: 4% to 12% of nano-titania, 0.5% to 2% of talcum powder, 5% to 15% of polyethylene glycol, 2% to 6% of benzotriazole and the balance of acetone; and the heat insulating layer is prepared from the following raw materials in parts by weight: 11-18 parts of perlite powder, 7-11 parts of bentonite, 4-9 parts of vermiculite, 2-4 parts of titanium white, 1-3 parts of thickener, 3-5 parts of humectant, 4-6 parts of leveling agent, 0.6-1.5 parts of silane compound, 6-10 parts of kaolin and 2-5 parts of bauxite. The heat-insulating glass with the ultraviolet-proof coating, disclosed by the invention, is relatively good in heat-insulating property and can be used for effectively preventing sunlight; and the heat-insulating glass has relatively high light transmittance and meanwhile can be used for effectively preventing ultraviolet rays from eroding human bodies.

Description

technical field [0001] The invention relates to a heat-insulating glass with an anti-ultraviolet coating, which belongs to the technical field of glass. Background technique [0002] Glass is a transparent semi-solid and semi-liquid substance, which forms a continuous network structure when molten, and is a silicate non-metallic material that gradually increases in viscosity and hardens during cooling. The main component of ordinary glass is silicon dioxide, which has high chemical stability, thermal stability and good transparency, so it is widely used in various fields. At present, most of the glass widely used by people is single-layer flat glass, which has good light transmission, but the thermal insulation effect is poor, and it cannot effectively block the heat of outdoor sunlight from entering the room, resulting in high indoor temperature and cannot be effectively Block ultraviolet rays, excessive ultraviolet rays can easily cause damage to the human body.
