Preprinted oil polish for high-temperature resistant carton

Abstract

The invention relates to the technical field of ink, in particular to preprinted oil polish for a high-temperature resistant carton. The preprinted oil polish comprises the following components in percentage by weight: 50 to 80 percent of acrylic resin emulsion, 5 to 20 percent of alkaline solubility colloid, 0.1 to 1 percent of defoaming agent, 0.1 to 1 percent of levelling agent, 1 to 10 percent of wax, 1 to 10 percent of ethanol and water. The preprinted oil polish has good lustrousness, ensures the corrugated compounding and using performance, and improves the high-temperature resistance by a higher level compared with similar high-temperature resistant ink prepared by acrylic resin; and the preprinted oil polish can resist high temperature of 240 DEG C maximally, can meet the requirement of high-grade printing, and has the advantages of simple preparation, low cost, environment friendliness, innocuity, stable performance, light air pollution, no residue of toxic solvent, and contribution to safe production and environmental protection.

Description

Technical field: [0001] The invention relates to the technical field of inks, in particular to a pre-printed varnish for high-temperature resistant cartons. Background technique: [0002] The traditional production of color corrugated cartons is to print directly on the die-cut cartons by flexographic printing technology. The cartons produced by this technology are simple in pattern, dirty in color and not bright enough, and the surface of the carton may be uneven due to excessive pressure. Corrugated phenomenon, this technology is generally used in lower-grade packaging. [0003] Then came the lithographic offset printing technology to produce cartons, using offset printing on a single carton surface paper, and then using a laminating machine to bond the printed surface paper and corrugated paper, and then die-cutting. The cartons produced by this method are rich in patterns, bright in color and saturated, but the production efficiency is still low, and the stability of pr...
