Explosion-proof membrane of window glass and preparation method of explosion-proof membrane

Abstract

The invention discloses an explosion-proof membrane of window glass. The explosion-proof membrane is prepared from the following raw materials in parts by weight: 35 to 40 parts of polyurethane, 45 to 50 parts of polyvinyl chloride, 8 to 10 parts of polyethylene terephthalate, 7 to 10 parts of nano copper, 11 to 14 parts of nano aluminum oxide, 6 to 12 parts of furan resin, 3 to 8 parts of nano ceramic, 4 to 8 parts of polyphenylene sulfide, 3 to 9 parts of cellulose ester, 15 to 22 parts of vinyl acetate, 4 to 7 parts of organic tin, 6 to 12 parts of magnesium stearate, 14 to 18 parts of phosphatase starch, 5 to 10 parts of phthalic anhydride, 6 to 10 parts of aminoethylpiperazine, 12 to 15 parts of ferric trichloride, 5 to 12 parts of hydroquinone, 12 to 15 parts of sodium antimonate, 5 to 8 parts of sorbitol ester and 6 to 9 parts of zinc sulfide. The explosion-proof membrane of the window glass, provided by the invention, has an explosion-proof function, also can be used for effectively resisting ageing, has a good anti-corrosion effect and is convenient to machine.

Description

technical field [0001] The invention relates to an explosion-proof film for window glass and a preparation method thereof. Background technique [0002] The explosion-proof membrane is a metal film installed on the upper part of the pressure vessel to prevent the vessel from exploding. It is a safety device. Also known as explosion-proof disc or bursting disc. When the pressure in the container exceeds a certain limit, the membrane will be broken first, thereby reducing the pressure in the container and avoiding explosion. It is widely used in pressure vessels. The term explosion-proof membrane sometimes refers specifically to the front windshield membrane. Due to the requirements of traffic safety, the front windshield film has extremely high requirements on light transmission. Ordinary solar film cannot be used for front windshield. Its price is much higher than the general solar film. At this time, explosion-proof has become the most important function of explosion-...

AI Technical Summary

Problems solved by technology

[0004] At present, the existing explosion-proof film adopts a multi-layer structure with general explosion-proof function, and at the same time, it cannot effectively prevent aging, has poor anti-wear effect, and is inconvenient to process.
