Optical adhesive for explosion-proof membrane and preparation method thereof

Abstract

The invention discloses an optical adhesive for an explosion-proof membrane. The adhesive is prepared from the following components in parts by weight: 80 to 100 parts of acrylate adhesive, 10 to 20 parts of rosin modified organic silicon resin, 3 to 5 parts of isocyano ethyl methacrylate, 3 to 6 parts of 2-[3-(2H-benzotriazole-2-yl)-4-hydroxyphenyl] ethyl 2-methacrylate, 7-fluoro-5-oxo-8-(4-(2-allyl)-1-piperazinyl)-5H-thiazolo [3, 2-b] pyrimidine-2-ketone, 3 to 6 parts of 2-(2-fluorophenyl)-2-(4-fluorophenyl)-1-piperazinyl]-1, 2, 3-triazole-2-yl)-4-(2-fluorophenyl)-1, 2, 3-triazole-2-yl)-1, 2, 3-triazole-2-yl) The invention relates to a photocurable coating which is prepared from the following components in parts by weight: 1 to 3 parts of 2, 2-a] quinoline-4-carboxylic acid, 0.3 to 0.5 part of diallyl sulfide, 10 to 15 parts of solvent, 0.6 to 0.8 part of photoinitiator, 0.1 to 0.3 part of allyl trimethoxy silane and 0.1 to 0.3 part of organic bismuth catalyst. The invention also discloses a preparation method of the optical adhesive for the explosion-proof membrane. The optical adhesive for the explosion-proof membrane, disclosed by the invention, is good in adhesive property, aging resistance, yellowing resistance, performance stability and mechanical property and long in service life.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an optical adhesive for an explosion-proof film and a preparation method thereof. Background technique [0002] Explosion-proof film is widely used in the fields of automobiles, photovoltaics, and electronic equipment because it can prevent glass from splashing and improve safety when the glass cover plate is broken. Rupture films typically include a hardcoat / substrate / adhesive layer structure. The adhesive layer is usually made of optical adhesive, and its performance directly affects the explosion-proof effect, safety and service life of the explosion-proof membrane. [0003] The existing optical adhesives for explosion-proof membranes have the advantages of high light transmittance, low haze, UV resistance, high adhesion, high temperature resistance, and no yellowing after long-term use. The market application potential is expected to become the "new darling" of the film c...
