Ultraviolet wear-resisting and thermal insulating glass

Abstract

The invention relates to an ultraviolet wear-resisting and thermal insulating glass. The ultraviolet wear-resisting and thermal insulating glass comprises a glass substrate, wherein an ultraviolet-proof coating and a thermal-protective coating are arranged on surfaces of the glass substrate, the ultraviolet-proof coating comprises the following components: 15-30 percent of waterborne polyurethane resin, 1-5 percent of polytetrafluoroethylene, 1-3 percent of a hydroxyphenyl benzotriazole ultraviolet absorber, 1-5 parts of sodium salt of polynaphthalene sulphonic acid, and 0.1-2 parts of a sorbitan ester emulsifier; the thermal-protective coating is prepared from the following raw materials: 50-100 parts of a styrene-acrylic emulsion, 30-50 parts of hollow microspheres, 1-10 parts of aluminium silicate fibre, 10-30 parts of silicon dioxide, 1-5 parts of texanol, 1-5 parts of hydroxyethyl cellulose and 0.1-0.5 part of a thermal insulation assistant. The ultraviolet wear-resisting and thermal insulating glass provided by the invention is relatively good in heat-insulating property, and can effectively prevent ultraviolet ray erosion.

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.
