Problems solved by technology

[0005] The object of the present invention is: to overcome the deficiencies in the prior art, provide a kind of transparent and non-yellowing UV varnish, through the effect of ultramarine ink and titanium dioxide in the UV varnish, solve the yellowing problem of UV varnish from a physical point of view Problem; by using acylphosphorus oxide as a photoinitiator, it not only solves the yellowing problem of UV varnish from the perspective of xanthometry, but also effectively improves the brightness of UV varnish; through tripropylene glycol diacrylate in UV varnish The role of the resin system can reduce the viscosity of the resin system and improve the fluidity of UV varnish; through the role of trimethylolpropane triacrylate in UV varnish, the curing speed of UV varnish can be improved; The role of methyl siloxane improves the wettability, surface smoothness and gloss of UV varnish and improves the defoaming of UV varnish; through aliphatic polyurethane acrylic resin, it has good flexibility and bright gloss Advantages, improve the brightness of UV varnish

Abstract

The invention discloses transparent non-yellowing UV gloss oil and a preparation method and an application method thereof. The transparent non-yellowing UV gloss oil is prepared from the following components: a photoinitiator, a reactive diluent, a surfactant, ultramarine printing ink, titanium dioxide and an oligomer according to the ratios in parts by weight of (2-3):(35-40):(1-2):(0.1-0.2):(5-8):(47-55). From the structure of the transparent non-yellowing UV gloss oil of the present invention, the problem of yellowing of the UV gloss oil is solved from a physical standpoint through the actions of the ultramarine printing ink and the titanium dioxide in the UV gloss oil.

Description

technical field [0001] The invention relates to the field of transparent and non-yellowing UV varnish, in particular to a transparent and non-yellowing UV varnish and a preparation method and application method thereof. Background technique [0002] As a commonly used ink in the printing industry, UV varnish is mainly used to coat printing paper or other materials to achieve bright and smooth finishing effects, and at the same time has the characteristics of rapid curing and basically no emission of volatile substances. However, in actual use, we found that UV varnish will turn yellow and darken when it is coated on lighter colors, especially when it is coated on white cardboard, it will turn yellow obviously and cannot reflect the true color of the substrate. It is a fly in the ointment. [0003] The reason is that the ingredients in the UV varnish react with the ingredients in the air to cause yellowing. In order to solve this technical problem, the laminating process is ...
