Problems solved by technology

Among them, for the vehicle with the lidar installed in the car, the signal of the lidar needs to be transmitted through the window glass. Signals with a wavelength of 1550nm or 1550nm have high transmittance, and the currently used car window glass has a high rejection rate for 780-2500nm infrared rays in order to meet the heat insulation requirements, which cannot meet the requirements of laser radar.

Abstract

The invention provides glass, a glass assembly and a vehicle. Wherein the glass comprises SiO2, Al2O3, Na2O, CaO, MgO, K2O, BaO, ZnO, TiO2, Sb2Ox and the total iron which is converted into Fe2O3. Wherein ZnO + TiO2 + Fe2O3 is smaller than or equal to Sb2Ox, and 10Fe2O3 + ZnO + TiO2 is larger than or equal to Sb2Ox. Therefore, the glass is adjusted by controlling the total iron content converted into Fe2O3 in the glass and adding ZnO, TiO2 and Sb2Ox with specific contents, so that ZnO, TiO2, Sb2Ox and the total iron converted into Fe2O3 are matched with one another to improve the infrared transmittance of the glass, and the glass with high infrared transmittance is obtained.

Description

technical field [0001] The application belongs to the technical field of glass, and in particular relates to glass, glass components and vehicles. Background technique [0002] With the application of glass more and more widely, users' demand for glass is gradually increasing. Among them, for the vehicle with the lidar installed in the car, the signal of the lidar needs to be transmitted through the window glass. Signals with a wavelength of 1550nm or 1550nm have high transmittance. Currently, the window glass used to meet the heat insulation requirements has a high rejection rate for 780-2500nm infrared rays, which cannot meet the requirements of LiDAR. Contents of the invention [0003] In view of this, the first aspect of the present application provides a glass, expressed in the following mass percentage based on oxides, the glass includes the following components: [0004] 55%~85% SiO 2 , [0005] 0%~10% Al 2 o 3 , [0006] 5%~20%Na 2 O, [0007] 5%~20% CaO, ...
