Energy-saving type transparent coating with functions of heat reflection and heat insulation

Abstract

The invention discloses an energy-saving type transparent coating with functions of heat reflection and heat insulation. The coating comprises components in parts by weight as follows: 10-30 parts of inorganic pigment, 0.5-25 parts of a solvent and 45-89.5 parts of resin, wherein the inorganic pigment comprises tin antimony oxide with the particle size of 10-80 nm, tin indium oxide and lanthanum hexaboride; the solvent is selected from one or more of alcohol, aliphatic hydrocarbon, aromatic hydrocarbon, ketone and ester solvents; the resin is selected from one or more of acrylate-based resin, polyurethane resin, inorganic silicon based resin, silica sol based resin and organic and inorganic mixed resin. The energy-saving type transparent coating with the functions of heat reflection and heat insulation can be applied on transparent glass directly exposed to the sun, thereby forming a coating film with the functions of heat reflection, heat insulation and energy saving, guaranteeing the transparency of the glass and having the continuous heat insulation effect, good visible light transmittance and certain stain resistance.

Description

technical field [0001] The invention relates to an energy-saving heat-reflecting heat-insulating transparent coating. Background technique [0002] Ordinary heat-insulating and heat-insulating coatings achieve heat-insulating and heat-insulating effects through hollow balls in the slurry and opaque white paint. This opaque white paint is mainly used to paint cement walls or roofs of buildings such as factories. [0003] As the main component of the building, the window cannot reflect the heat insulation effect well because of the transparency of its glass. Sunlight will shine directly through the glass and heat up. Heat from inside the building is also released through the glass, causing heat loss. In winter, the heat in the room will be conducted to the outside through the glass, causing an increase in heating costs. In summer, the heat from the outside will be transferred to the room through the glass, resulting in an increase in cooling costs. [0004] In recent year...
