Problems solved by technology

[0005] In the market, in the production of most mobile phones, in order to prevent cracking, the film is put on the inside during use. At the same time, the yield rate of the film in China is low, and there are hidden dangers in practice; at the same time, the protective film is carried out at the back end.

Abstract

The invention provides a composition of a water-based high-extensibility explosion-proof coating. The composition is prepared from, at least, water-based polyacrylate, anionic polyurethane water-baseddispersion, a leveling agent, a wetting agent, pure water and dimethyl maleate. The water-based glass explosion-proof adhesive is the coating with water as a diluent, and volatized organic solvent isvery little and is only 5%-10% of a solvent type coating, so there is no problem of free TDI volatilization, and the coating is an environment-friendly product. The water-based glass explosion-proofadhesive can be prevented from being scattered after bursting and can also produce no residue after tearing again.

Description

technical field [0001] The invention relates to the field of glass production, and more particularly to a composition of water-based high-extendability explosion-proof coating. Background technique [0002] Since the 1990s, the solvent-based coatings, paints and adhesives industry has gradually shifted from traditional varieties with high pollution, high energy consumption and extreme dependence on petroleum industry products to environmentally friendly, resource and energy-saving products. Varieties continue to emerge, among which the water-based coating and water-based adhesive industries have made great progress. Water-based coatings have the advantages of low price, safe use, saving resources and energy, reducing environmental pollution and public hazards, etc., so it has become the main direction of the current development of the coatings industry. Water-soluble coatings mainly refer to water-soluble resins as film-formers, as well as inorganic polymer water-based resi...
