A kind of UV light curing anti-fog resin and its preparation method and application

Abstract

The invention relates to novel UV (Ultraviolet) light-curable anti-fog resin as well as a preparation method and application thereof. The structural formula of the UV light-curable anti-fog resin is as follows: the formula is shown in the description, wherein the value range of x is 1 to 6; the value range of y is 2 to 8; the value range of z is 9 to 16; R1 is one or more of C1 to C13 alkyl groups; the molecular weight of the UV light-curable anti-fog resin is 1500 to 3200. Light-curable coating prepared by the novel UV light-curable anti-fog resin provided by the invention serving as a raw material has relatively good anti-fog performance, rigidity and adhesive force. The UV light-curable anti-fog resin provided by the invention is mutually dissolved with a photoinitiator, an auxiliary agent and the like; the prepared UV light-curable anti-fog coating can be cured into a film under the illumination of a UV lamp; a film body has the characteristics of high transparency, good film forming performance, good compatibility, good toughness and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a UV photocurable anti-fog resin and its preparation method and application. Background technique [0002] The water vapor in the air condenses into fine water droplets on the surface of glass or transparent plastic, and the continuous accumulation of water droplets on the surface makes these transparent materials blurred and opaque, affecting people's production and life, so preventing the generation of fog from changing production and life is particularly important. Anti-fog treatment methods mainly include electrothermal method and anti-fog coating method. The electric heating anti-fog method is to equip the equipment that needs anti-fog with an electric heating device. By heating, the surface temperature of the equipment is raised, and the mist evaporates quickly without forming a fog layer, so as to achieve the purpose of anti-fog. This method has a good anti-fog ...

AI Technical Summary

Problems solved by technology

Zoromba etc. have prepared a kind of polyurethane acrylate coating, reacts with isophorone and HEA and then prepares the polyurethane acrylate anti-fog coating with polyethylene glycol modification, can be applied to plexiglass, polyester synthetic fiber, polycarbonate And other substrate surfaces, its anti-fog performance is excellent, because the polyethylene glycol structure makes it flexible but poor adhesion to the substrate

Zhao Ziqian used photosensitive acrylate oligomer as the matrix to polymerize with HEA, AM, TPGDA, and added photoinitiator additives, etc., to prepare a light-cured anti-fog coating. The research found that the anti-fog performance of the coating film is excellent. Among them, TPGDA (Tripropylene glycol diacrylate) makes it have good adhesion to the substrate, but the hardness of the cured paint film is not high, and it is not resistant to scratches and friction

Fumio Tanabiki in foreign patent US 9084982B2 invented a solvent-based acrylic resin obtained by copolymerization of methyl methacrylate and N,N-dimethylacrylamide. The anti-fog coating prepared by this method has good anti-fog performance and high gloss , The film is uniform, but the service life of the anti-fog is short, the adhesion with the substrate is poor, the compatibility is not good, it is easy to scratch, and it may fall off, etc., which will affect the anti-fog effect and appearance.
