Problems solved by technology

At present, UV varnish varnish has a good coating effect on printed packaging products, but the resistance of most varnishes is not ideal, especially for chemical solutions or solvents, such as acidic or alkaline solutions, and organic solvents, such as ethanol The tolerance of solutions, etc. is poor, and the UV varnish coating is easy to change color after contacting with these solutions or solvents for a period of time, thus affecting the appearance of printed matter

Abstract

The invention provides UV gloss oil and application thereof, and relates to the technical field of gloss oil. The UV gloss oil comprises the following components in parts by mass: 3-8 parts of prepolymer, 80-90 parts of acrylic monomers, 4-10 parts of free radical photoinitiator and optional auxiliaries, wherein the prepolymer comprises an unsaturated oligomer containing polymerizable carbon-carbon double bonds, and the functionality of the prepolymer is 2-18; and the acrylic monomers comprise at least two of EOEA, HDDA, TPGDA, NGPDA, ACMO, DPGDA, TMPTA, IBOA, DEGDA, TEGDA, BDDA, PDDA, DTMPTA,DPPA and DPHA. The UV gloss oil has good resistance to chemical solutions or solvents.

Description

technical field [0001] The invention relates to the technical field of varnish, in particular to a UV varnish and its application. Background technique [0002] Varnish, also known as varnish, is a colorless, transparent or translucent ink. The film-forming process of varnish is the process in which the varnish coated on paper changes from liquid to solid. Printed matter glazing can increase the printing gloss, protect the printed matter surface, and improve the friction resistance, chemical resistance and water resistance of the printed matter. [0003] With the improvement of printing processing technology, people have higher and higher requirements for the surface decoration of printed matter, and its quality and durability have become extremely important. UV curing technology is gradually mature, and its application in the field of printing and packaging is becoming more and more popular. The UV curing process is a photochemical reaction process. Under the action of u...
