Abstract

The invention relates to ultraviolet wear-resistant heat-protecting glass. The ultraviolet wear-resistant heat-protecting glass comprises a glass base material, wherein an ultraviolet-proof layer and a thermal insulation layer are arranged on the surface of the glass base material; the ultraviolet-proof layer comprises the following components: 15-30% of waterborne polyurethane resin, 1-5% of polytetrafluoroethylene, 1-3% of a hydroxybenzotriazole ultraviolet absorbent, 1-5% of sodium methylene bisnaphthalene sulphonate and 0.1-2% of a sorbitan ester emulsifier; and the thermal insulation layer is prepared from the following raw materials in percentage by weight: 25-40% of film forming matters, 15-30% of silica, 5-10% of zinc oxide, 1-3% of a dispersing agent, 1-3% of an antifoaming agent and the balance of solvents. The ultraviolet wear-resistant heat-protecting glass disclosed by the invention has an excellent heat-insulating property, and ultraviolet erosion can be effectively prevented.

Description

technical field [0001] The invention relates to an ultraviolet wear-resistant and heat-insulating glass, 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.
