Liquid self-repairing hydrophobic glass based on negative pressure technology

Abstract

The invention discloses liquid self-repairing hydrophobic glass based on a negative pressure technology, belongs to the field of glass repairing, and adopts the scheme that when a vehicle runs, microcrystal grains of copper oxide and silver bromide react with sunlight, and when the vehicle is irradiated by strong light, the microcrystal grains of copper oxide react with silver bromide, so that theliquid self-repairing hydrophobic glass is formed. Silver bromide is decomposed into silver and bromine tiny crystal grains, the stimulation degree of sunlight to eyes is effectively reduced, and when the glass is damaged, rainwater is not prone to adhering to the surface of the glass through the hydrophobic layer, so that the light transmittance of the glass is improved, wiping of the glass is reduced, and secondary damage to the glass is reduced. When the liquid repairing glue permeates to the surface of the glass, the liquid repairing glue is adsorbed to the damaged position through negative pressure covering the damaged position and the interior of the empty space layer, continuous expansion of cracks is reduced through tension between the repairing film and the glass, and the repairing effect is improved. Therefore, the strength of the repaired part of glass is improved.

Description

Technical field [0001] The invention relates to the field of glass repair, and more specifically, to a liquid self-repairing hydrophobic glass based on negative pressure technology. Background technique [0002] The production of automobile glass is by heating the glass in a heating furnace to close to the softening temperature, and then quickly sending the glass into the wind grid with different cooling strengths to cool the glass unevenly, so that the main viewing area of ​​the glass and the surrounding area are different Stress, generally this kind of produced glass is regional tempered glass. [0003] The surrounding area is in the strong wind position of the wind grid, so it needs to be fully tempered. This location has good fragmentation and high strength. The main viewing area is in the weakly cold position of the wind grid, with large fragments and low strength. [0004] Automobile glass is indispensable in automobile body accessories. It mainly plays a protective role. Ther...

Problems solved by technology

[0006] At present, when the vehicle encounters stones and broken glass during high-speed driving, it often happens that the car must be picked up to check whether the glass will affect the continued use. When the vehicle is running at high speed and it is not convenient to stop for inspection, the damaged glass will have a great impact driving safety
