Problems solved by technology

[0003] The green glass used in existing automobiles can also achieve the purpose of reducing the transmission of infrared rays and ultraviolet rays to a certain extent, but it is usually thicker, such as greater than 2.1mm, which cannot meet the requirements of lightweight automobiles and has a lower glass thickness. Requirements for infrared transmittance and ultraviolet transmittance

Abstract

The invention discloses a dark sun green glass. The dark sun green glass comprises a glass basic component and a glass coloring component, the thickness of the prepared dark sun green glass is 1.6-2.1 mm, the solar energy transmittance is less than or equal to 65%, the infrared ray transmittance is less than or equal to 45%, and the ultraviolet ray transmittance is less than or equal to 35%. According to the invention, the thickness of the glass is reduced, and the solar energy transmittance, infrared ray transmittance and ultraviolet ray transmittance of the glass can be reduced at the same time.

Description

technical field [0001] The invention relates to the field of original glass sheets, in particular to provide a deep solar green glass with lower infrared transmittance and ultraviolet transmittance. Background technique [0002] Glass products are widely used in construction, automobile, household, medical, chemical, home furnishing, electronics, instrumentation and other industries. With the advancement of production technology, the performance and color requirements of glass products are continuously improved and met. Glasses of different colors are gradually applied to more mid-to-high-end and special-performance cars. The optical changes of glass endow the glass with different colors and properties. In the application of automotive glass, dark glass products can be used as side window glass, rear windshield glass, panoramic sunroof, etc. to protect the privacy of the car interior space and To achieve the purpose of reducing the incidence of infrared rays and ultraviolet...
