Problems solved by technology

[0004] However, people's requirements for the performance of printed matter are also getting higher and higher. In order to improve the gloss of varnish gold oil, a large amount of water-based resin will be added, but the compatibility between some water-based resins is poor, resulting in a decrease in cross-linking density and lower Abrasion resistance of varnish gold oil

Abstract

The invention discloses a waterborne over-printing gold varnish and a preparation technology thereof. The waterborne over-printing gold varnish is characterized by being prepared from, by mass, 30-40 parts of modified waterborne acrylic acid resin emulsion, 30-40 parts of modified waterborne polyurethane resin emulsion, 10-15 parts of methylated amino resin, 1-10 parts of deionized water, 1-5 parts of neutralizer, 1-5 parts of anti-wear auxiliary, 1-5 parts of hardening auxiliary, 0.1-0.5 part of defoaming agent and 0.1-0.5 part of antibacterial agent. The waterborne over-printing gold varnish can be used for spray painting and printing of various kinds of metal and glass, and has the advantages of being free of solvent volatilization, environmentally friendly, free of air pollution, high in printing ink hardness, good in gloss, good in fullness and identical with solvent type stoving varnishes in salt mist resistance and the like.

Description

technical field [0001] The invention relates to printing ink, in particular to a water-based varnish gold oil and a preparation process thereof. Background technique [0002] With the development of printing products and people's attention to the environmental protection of products, the development of water-based varnish has been paid more and more attention by people. Compared with solvent-based varnish, the content of volatile organic compounds in water-based varnish Low, with little harm to the human body, it is gradually replacing solvent-based varnish gold oil. [0003] For example, the publication number is CN102618158A, a kind of water-based gold oil for soft PVC coating, which is composed of A component and B component, and the weight ratio of A component and B component is 8-10:1, wherein A group Substances include the following parts by weight: high molecular weight water-based polyurethane dispersion 67-90%, deionized water 3.5-30%, leveling agent 0.5-1%, disper...
