Abstract

The invention belongs to the technical field of glass, and particularly relates to medium-aluminum glass capable of absorbing ultraviolet rays and a preparation method and application of the medium-aluminum glass. The medium aluminum glass comprises the following components in percentage by weight: 59%-66% of SiO2, 8%-12% of Al2O3, 13%-18% of Na2O, 5%-8% of K2O, 3%-8% of MgO and 0.2%-1.2% of CeO2, wherein the total amount of the SiO2, the Al2O3, the Na2O, the K2O and the MgO is 100%. The ratio of the total mass of CeO2, K2O and Na2O to the mass of Al2O3 is 1.75 to 3. The medium-aluminum glass capable of absorbing the ultraviolet rays has excellent ultraviolet ray absorption efficiency, low softening point temperature and high stress layer depth, is particularly suitable for the fields of automobile body glass and the like, can meet the requirement of hot bending shaping of the automobile body glass, has strong absorption on the ultraviolet rays, reduces the harm of ultraviolet radiation to a user, and is suitable for popularization and application. Meanwhile, the visible light transmittance is high, and the visual field of a user cannot be affected.

Description

technical field [0001] The application belongs to the technical field of glass, and in particular relates to an ultraviolet absorbing medium aluminum glass and a preparation method thereof, and an application of an ultraviolet absorbing medium aluminum glass. Background technique [0002] Although ultraviolet rays have the effect of killing bacteria, they can also destroy human skin cells, causing skin problems such as wrinkles and pigmentation, making the skin prematurely senile, and in severe cases, it will lead to solar dermatitis and sunburn, or sunlight on the skin and mucous membranes. Sexual keratosis, causing cancer. In addition, the eye is a sensitive organ of ultraviolet rays, and ultraviolet rays can cause damage to the lens, which is one of the pathogenic factors of senile cataracts. Therefore, it needs to be avoided in some occasions, especially in hot summer. [0003] With the improvement of people's living standards, the number of cars has also increased. Al...
