Problems solved by technology

The varnishes used in traditional gold and silver printing are all benzene solvent-based. Although this kind of varnish has stable components and can ensure the full dissolution and dispersion of gold powder and silver powder to achieve an ideal printing effect, it must be benzene-based. substance as solvent
Benzene is a highly toxic solvent, and its hazards are reflected in: (1) damage to the body of the operator, especially the hematopoietic function (2) pollution to the environment (3) cumulative damage to the health of consumers
Although most of the benzene solvent added to the printing ink is volatilized during the drying process, there is still a certain amount of residue on the finished product, which is harmful to the health of consumers over time.

Abstract

A non-benzene gold blending oil consists of resin, solvent and printing ink accessory. It has good viscosity and wetting ability, better transparency, quick drying and curing performances.

Description

technical field [0001] The invention relates to a kind of gold-adjusting oil, which is used to blend gold powder and silver powder in the printing process to make printing gold and silver-colored inks, and is especially suitable for gold-and-silver printing in tipping paper. It is composed of resin, Composed of solvents and ink additives. Background technique [0002] Like other inks, gold and silver inks are mainly composed of pigments and binders. Simply put, gold ink is made of gold powder and gold-adjusting oil, and silver ink is made of aluminum powder and silver-adjusting oil. (also known as gold-adjusting oil) is prepared. The binder is the liquid component in the ink. On the one hand, it is the carrier of the pigment, so that the powdered pigment particles can be uniformly dispersed in it; The surface of the substrate material. The binder determines the viscosity, viscosity, fluidity and drying performance of the ink to a large extent. Therefore, the quality of th...
