Problems solved by technology

However, the traditional water-based coating varnish is alkaline, and after the coating is dried and then bronzing, it is inevitable that there will be alkaline substances that may corrode the anodized aluminum, resulting in poor performance of the water-based varnish

Abstract

The invention relates to the technical field of coating varnish, in particular to anti-oxidation emulsion and anti-oxidation waterborne coating varnish prepared from the same. The anti-oxidation emulsion is prepared from raw materials in percentage by weight as follows: 30%-50% of an acrylic resin solution with neutral pH, 29%-41% of mixed monomers, 0.5%-1% of an emulsifier, 0.3%-0.8% of an initiator, 0.01%-0.05% of an oxidizing agent, 0.01%-0.05% of a reducing agent and 10%-25% of deionized water, and the sum of the raw materials in percentage by mass is 100%. According to the anti-oxidation emulsion, possibly existing acid-base substances can be reduced, the probability of oxidation is reduced, and hot stamping foil is not prone to oxidation; the anti-oxidation waterborne coating varnish prepared from the anti-oxidation emulsion contains no organic solvents, is low in content of VOCs (volatile organic chemicals) or free of VOCs, is environment-friendly, non-toxic and anti-oxidation, and is suitable for surface lustering of substrates, prone to hot stamping oxidation, of black cardboards, blackened paper, coated black paper and the like.

Description

technical field [0001] The invention relates to the technical field of coating varnish, in particular to an anti-oxidation emulsion and an anti-oxidation water-based coating varnish prepared by using the same. Background technique [0002] Hot stamping paper (also called hot stamping foil) can be divided into gold, silver, and color. Hot stamping gold is called hot stamping, and hot stamping silver is called hot silver, commonly known as hot stamping. Hot stamping paper has a special metallic luster, which brings bright colors to the hot stamping, improves the grade of the product, and has a fashionable look, so it is widely used in the packaging field, such as cosmetic packaging boxes, gift jewelry boxes, high-end shoes boxes and more. [0003] Hot stamping is a process of transferring the pattern on the hot stamping paper to the substrate by means of thermal transfer through appropriate temperature and pressure. Generally, the water-based ink is first printed on the pape...
