Environment-friendly high-temperature-resistant explosion-proofmembrane

Abstract

The invention discloses an environment-friendly high-temperature-resistant explosion-proof membrane which sequentially comprises a scratch-resistant wear-resistant layer, a safety explosion-proof layer, an ultraviolet absorption layer, a PET (polyethylene terephthalate) carrier layer, a pressure-sensitive adhesive layer and a release film layer. The scratch-resistant wear-resistant layer is prepared from the following raw materials in parts by weight: 30-50 parts of acrylic resin emulsion, 25-36 parts of isobutyl etherified amino resin emulsion, 2-6 parts of wood fiber, 0.5-1.3 parts of succinic anhydride, 1-3 parts of konjaku flour nanocrystal, 2-4 parts of vermiculite powder, 0.1-0.5 part of dispersing agent and 10-15 parts of deionized water. The safety explosion-proof layer is prepared from the following raw materials in parts by weight: 20-40 parts of fluorocarbon-modified polyacrylic resin emulsion, 5-11 parts of polytetrafluoroethylene resin, 6-10 parts of acrylic-acid-modified organic silicon resin, 2-3 parts of nano titanium nitride, 3-8 parts of sorbitan monocarboxylate, 1-4 parts of hollow silicon dioxide nanoparticle, 0.8-1 part ofcrosslinking agent, 3-5 parts of curing agent and 8-12 parts of deionized water. The explosion-proof membrane has the advantages of favorable scratch resistance, favorable wear resistance, excellent ultraviolet resistance, favorable explosion resistance, high interlaminar binding force, high safety, high transparency and high temperature resistance.

Description

[0001] Technical field: [0002] The invention relates to the field of thin films, in particular to an environment-friendly high temperature resistant explosion-proof membrane. [0003] Background technique: [0004] With the acceleration of my country's urbanization process, more and more high-rise buildings have sprung up. In order to enhance the lighting effect, viewing effect and aesthetic effect of building facades in modern architectural design, more glass structures are used. The application of open floor design, glass canopy and large area of ​​floor-to-ceiling glass has gradually become fashionable. However, while these designs bring beauty to people, they also bring us a lot of troubles. For example: the use of large areas of glass causes energy waste; glass is a brittle material that is easily broken by stress and produces fragments. Although tempered glass is broken into particles without sharp corners, it is easy to splash and cause personal injury under the act...
