Abstract

The invention discloses a kind of high-adhesion anti-yellowing gloss oil. Adopted matrix resin is 6-functionality amino acrylate resin, so that the curing speed is high, and the cost is lower than those of modified epoxy or polyurethane acrylate resins. Trimethylolpropane triacrylate (TMPTA) and neopentyl glycol diacrylate (NPGDA) are taken as active diluents, so that the system viscosity is lowered, the glossiness is increased, the shrinkage rate is controlled, and the adhesion is improved; an adhesion promoter enhances the mutual acting force with a substrate, so that the adhesion is better. An initiator is high in initiation efficiency, and has an excellent yellowing resistance.

Description

technical field [0001] The invention relates to a synthetic resin, in particular to a UV-curable varnish, which is specifically applied to plastic substrates such as PVC, polystyrene and polyolefin, has high adhesion and yellowing resistance, and increases its decorative use value . Background technique [0002] With the improvement of product quality requirements, UV-curable varnishes for plastic substrates currently on the market need good adhesion, no yellowing, low cost requirements, and a balance of fullness, leveling, and curing speed. . [0003] Chinese invention patent ZL200410015113.5 discloses a UV-curable printing varnish, which consists of 65%-70% epoxy prepolymer, 26%-32% polyol, 2%-4% polyarylsulfonium salt and Additives 0.5%-1.0% composition. The varnish technical solution overcomes the volume shrinkage of free radical curing varnish, enhances coating adhesion and flexibility, reduces deformation of printed matter, and has strong yellowing resistance.
