Abstract

The invention discloses water-based white ink. The formula comprises 30%-50% of water-based resin, 30%-60% of titanium dioxide, 3%-10% of wax powder, 2%-4% of zinc stearate, 1% of a water-based defoaming agent, 0.3%-0.7% of a water-based dispersing agent, 1%-2% of a water-based anti-scraping agent, 2%-5% of a polyester emulsion, 12%-25% of epoxy resin and 15%-30% of water. The water-based white ink is light in smell, does not pollute the environment, does not cause danger in hot weather in summer, and also reduces harm of the light smell to the body of a field operator; the adhesive force on aPET material is very strong, the shading property is also very strong, and the market prospect is very good.

Description

technical field [0001] The invention relates to an ink, in particular to a water-based white ink. Background technique [0002] Ink is a substance used to form graphic information in the printing process, so ink plays a very important role in printing. It directly determines the tone, color, and clarity of the image on the printed matter. In printing, we need to understand the composition of ink and the classification of ink. As printing, paper and other requirements become higher and higher, the technical conditions required for inks have also increased. [0003] Now the white inks on the market are all solvent-based. Solvent-based inks have a strong smell and cause great environmental pollution, which is harmful to the on-site operators. The hot weather in summer is very dangerous for solvent-based inks. Therefore, the present invention provides a water-based white ink. Contents of the invention [0004] The object of the present invention is to provide a kind of wate...
