Abstract

The invention relates to the technical field of transparent heat absorption coating layers, especially relates to an infrared absorption coating layer applied to the surface of glass, and concretely provides a coating liquid capable of forming the infrared absorption coating layer, an infrared absorption glass, and a manufacturing method of the glass. The infrared absorption coating liquid comprises infrared absorption nano-particles and a hydrolysis condensate of a hydrolyzable silane compound, and further comprises a nonmetal element being not Si and being able to form a triangular coordination or a tetrahedral coordination together with O, and the infrared absorption nano-particles are wrapped with the hydrolysis condensate of the hydrolyzable silane compound in situ to form an infraredcore-shell structure. The hardness and the friction resistance of the infrared absorption coating layer are ensured; the high temperature resistance and the durability of the infrared absorption coating layer are improved; and the infrared absorption glass having the advantages of good transparency, realization of the infrared absorption rate of the coating layer with a thickness of 4-6 [mu]m being more than 50%, high hardness, good friction resistance, excellent high temperature resistance and excellent durability is finally obtained.

Description

[0001] Technical field: [0002] The invention relates to the technical field of transparent heat-absorbing coatings, in particular to infrared-absorbing coatings coated on the surface of glass, and specifically provides a coating liquid capable of forming an infrared-absorbing coating, and an infrared-absorbing coating provided with the infrared-absorbing coating. The invention provides an absorbing glass, and also provides a method for preparing the infrared absorbing glass. [0003] Background technique: [0004] When driving under the scorching sun, infrared rays can enter the car through the window to make the temperature inside the car rise and become stuffy, and when it irradiates the human body, it will produce an uncomfortable burning sensation, forcing the driver to turn on the car's air conditioner, which will inevitably increase the fuel consumption of the car , especially for electric vehicles, turning on the car air conditioner will significantly reduce its batter...
