UV photocureable coating and preparation for vehicular touch screen rupture pressure disc hardening coat

The invention belongs to UV photocureable coating field, disclose a kind of with superpower scratch resistance performance and hydrophobic oleophobic anti-pollution characteristic, the UV photocureable coating and preparation method and application for vehicular touch screen rupture pressure disc hardening coat and the cured film based on which.Coating of the present invention includes the composition of following mass fraction meter：20～50 parts of polyfunctional acrylic ester monomer, 1～5 part of polythiol monomer, 0.1～1 part of resistant auxiliary agent, 1～5 part of nanoparticle, 1～3 part of light trigger, 40～80 parts of organic solvent；Described polyfunctional acrylic ester monomer is the acrylate reactive diluent of 4～6 degrees of functionality.The present invention also provides a kind of cured film obtained based on which, has superpower resistance to steel wool scratch performance (water contact angle >=105 °), stable hydrophobic oleophobic anti-pollution characteristic and pliability concurrently, compares existing PET hardening film properties and realizes complete upgrading；The coating mode of production, UV photocurings, both improve production efficiency, reduced production cost again.
