AI Technical Summary

Problems solved by technology

If the surface tension of the isolation oil is too small and the surface smoothness is too high, it will seriously affect its recoatability, which is not conducive to the flat spread of the scratch-off ink, and even cause the adhesion effect of the scratch-off ink layer to become poor and easy to fall off; If the surface tension of the oil is too small and the surface smoothness is too low, it is not conducive to the easy scraping of the scraping layer, or the clarity of the information after scraping is not good

Abstract

The invention belongs to the technical field of UV isolation oil and in particular relates to UV isolation oil applicable to instant lottery ticket printing and a preparation method of the UV isolation oil. The UV isolation oil comprises the following components in parts by weight: 5-15 parts of epoxy acrylate, 5-15 parts of a modified acrylic resin, 0.05-0.1 part of polydimethylsiloxane, 0.05-0.1part of trimethyl cyclosiloxane, 55-80 parts of a reactive diluent, 8-15 parts of a photoinitiator and 1-5 parts of an initiator aid. According to the UV isolation oil provided by the invention, thevarious components are reasonably matched and achieve a synergistic effect, so that the UV isolation oil has the advantages of excellent stability, moderate surface tension and smoothness, excellent adhesiveness, excellent wear resistance, simplicity in curing and the like, and the preparation method is simple, pollution-free and odor-free and facilitates industrial production.

Description

technical field [0001] The invention belongs to the technical field of UV isolation oil, and in particular relates to a UV isolation oil suitable for printing instant lottery tickets and a preparation method thereof. Background technique [0002] An instant lottery ticket is a printed paper product of specific specifications. For each instant lottery ticket, it usually includes a game area and a scratch area. The game area is printed with game rules, and the scratch area is printed with scratch numbers and / or winnings number, and the surface of the scratch area is covered with a thin film coating. After buying an instant lottery ticket, the lottery scratches off the coating of the scratch area, and checks the revealed scratch numbers with the winning numbers set by the game rules, so as to determine whether to win a prize and the winning amount. In order to ensure the "safety" of the scratch area, there are strict regulations on its production equipment, printing methods, a...
