Problems solved by technology

[0004] At present, due to the limitation of technical capabilities, the gloss and wear resistance of many water-based varnishes are not good enough. During use, the water in water-based varnishes will affect the paper, and the paper will be slightly deformed, which will reduce the glazing effect.

Abstract

The invention relates to the technical field of gloss oils, in particular to an environment-friendly highlight waterborne gloss oil and a preparation method thereof. The environment-friendly highlightwaterborne gloss oil is prepared from, by weight, 40-60 parts of soft monomers, 20-40 parts of hard monomers, 15-25 parts of functional monomers, 1-3 parts of an initiating agent, 3-5 parts of a dispersion agent, 2-4 parts of a flatting agent, 1-2 parts of a defoaming agent, 0.5-1.5 parts of a film formation assistant and 20-40 parts of deionized water. The environment-friendly highlight waterborne gloss oil has good film formation performance and compatibility and excellent base material adhesiveness and is high in glossiness, adhesive property and abrasive resistance, high in stain resistance, good in water resistance and acid and alkali resistance, resistant to ageing, breaking and adhesion, free of toxins and unpleasant odors, low in carbon, environmentally friendly and low in cost.

Description

technical field [0001] The invention relates to the technical field of varnish, in particular to an environment-friendly high-gloss water-based varnish and a preparation method thereof. Background technique [0002] Water-based varnish is a technical method for coating the surface of paper, and after drying and curing, it can greatly improve the gloss, smoothness and compactness of the paper surface, thereby improving the aesthetics of paper products. [0003] In the past, solvent-based products were mostly used for glazing oil. Although the glazing effect is good, the solvent volatilizes in large quantities. On the one hand, it will pollute the environment and harm the health of operators, and on the other hand, it is very easy to cause fire. With the improvement of human health awareness, it has become a common practice in the market to replace oil-based varnish with water-based varnish. [0004] At present, due to the limitation of technical capabilities, the gloss and w...
