Anti-ultraviolet composite fireproof glass

Abstract

The invention discloses a fireproof composite structure glass that can effectively block ultraviolet rays. The glass includes two glass substrates, between which a fireproof layer is stuffed. The fireproof layer comprises, by weight: 50% of methyl methacrylate, 15% of dibutyl ester, 20% of sodium sulfite, 1.3% of zinc oxide (ZNO), 3% of magnesium hydroxide, 0.2% of benzyl butyl phthalate, 10% of acrylamide, 0.1% of ethanol, and 0.4% of 2-hydroxy-4-methoxybenzophenone. By adopting the fireproof layer with the formula, ultraviolet rays can be effectively blocked, good fire resistance can be achieved, and the fireproof layer is unlikely to undergo foaming under a long-term use state, therefore, the light transmission performance is good.

Description

【Technical field】 [0001] The invention belongs to the field of fire-resistant glass materials, in particular to composite fire-resistant glass with the function of preventing ultraviolet rays. 【Background technique】 [0002] Anti-ultraviolet composite fireproof glass is a structure filled with a fireproof layer between two pieces of glass. When irradiated by ultraviolet rays, the special proportion of the fireproof layer can effectively cut off the ultraviolet rays and has good light transmission; when a fire occurs, the special proportion of the fireproof layer will be Through foaming and expansion, a large amount of heat transferred by the flame is absorbed, and the heat generated by combustion is prevented from being transferred from the fire side to the back fire side. In actual use, ordinary composite fire-resistant glass has a weak ability to penetrate and block ultraviolet rays, and under long-term ultraviolet radiation, the fire-resistant liquid will turn milky white...

AI Technical Summary

Problems solved by technology

In actual use, ordinary composite fireproof glass has a weak ability to penetrate and block ultraviolet rays, and under long-term ultraviolet radiation, the fireproof liquid will turn milky white and generate bubbles, losing the transparent function of glass, thus limiting its application range

However, ordinary film or coated UV-resistant glass is also due to the limitation of service life, especially in places where the temperature is slightly higher such as sunlight, its aging speed continues to accelerate, the film layer and coating gradually deteriorate, and the efficacy weakens over time.
