Problems solved by technology

The vehicle-mounted explosion-proof membrane materials used in the domestic market mainly rely on imports. The commonly used brands include Japan Prince, NEW TAC, DIC, Fujimori, Sony Chemical, etc. These brands are expensive, have long supply cycles, and long response times for after-sales services
At present, the quality stability and performance balance of domestic coated explosion-proof membrane products are poor, and they cannot compete with imported materials. There is still a large gap in the market demand for explosion-proof membranes.

Abstract

The invention belongs to the field of UV photocureable coatings, and discloses a UV photocureable coating which is extremely high in scratching resistance and hydrophobic and oleophobic anti-pollution property and is used for an explosion-proof membrane hardening coating of a vehicle-mounted touch screen, a preparation method and application of the UV photocureable coating and a hardening membrane based on the UV photocureable coating. The coating is prepared from the following components in parts by mass: 20 to 50 parts of a mulfunctional acrylate monomer, 1 to 5 parts of a sulfur alcohol monomer, 0.1 to 1 part of a fouling resistant additive, 1 to 5 parts of nano particles, 1 to 3 parts of a photoinitiator and 40 to 80 parts of an organic solvent, wherein the mulfunctional acrylate monomer is an acrylate active diluent with the mulfunctional level of 4 to 6. The invention further provides the hardening membrane obtained on the basis of the UV photocureable coating. The hardening membrane is extremely high in steel wool starching resistance (with water contact angle greater than or equal to 105 degrees) and stable in hydrophobic and oleophobic anti-pollution property and flexibility. Compared with the conventional PET hardening membrane, the hardening membrane based on the UV photocureable coating can realize comprehensive upgrading of the performance; and by the coating production mode and UV photocuring, the production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of UV light-curing coatings, in particular to a UV light-curing coating with super scratch resistance and hydrophobic, oleophobic and stain-resistant properties, which is used for the hardened coating of the explosion-proof film of the vehicle touch screen, its preparation method and application and based on its hardened film. Background technique [0002] Explosion-proof film, also known as glass anti-shatter film, is a functional film material used to prevent damage from splashing when glass is broken. The explosion-proof film for vehicles is a kind of subdivision of explosion-proof films. It is mainly used on the outer / inner surface of the glass cover of the vehicle touch screen to prevent the glass fragments from splashing when the glass is broken and hurting the user. The explosion-proof film structure includes a protective film layer, a hardened layer, a PET substrate, an adhesive layer and a release layer in s...
