Problems solved by technology

[0003] The advantages of the above-mentioned solvent-based printing ink are that the drying speed is relatively fast and the production time is short, but the solvent used will volatilize into the atmosphere and cause environmental pollution.
In order to solve this disadvantage, the existing technology has developed pure water-based printing ink, that is, using pure water as a solvent, the problem of pollution is solved, but the drying speed is too slow and the production capacity is too low, which makes printing manufacturers unwilling use

Abstract

The invention discloses quick-drying printing ink for soft PVC. The printing ink comprises, by mass, 30 to 50 percent of modified waterborne polyurethane resin, 2 to 5 percent of waterborne acrylic resin, 10 to 20 percent of water, 0.3 to 2 percent of a wetting agent, 5 to 10 percent of pigment, 1 to 3 percent of a dispersing agent, 0.1 to 2 percent of a defoaming agent, 0 to 1 percent of a pH regulator, 1 to 5 percent of wax emulsion, 1 to 3 percent of anti-settling powder and 20 to 29 percent of ethanol, the sum of the contents of all the components being 100%. The invention discloses a preparation method of the quick-drying type printing ink for the soft PVC, the ink printing drying speed is high, large-scale quick production can be achieved, and the productivity is effectively improved.

Description

technical field [0001] The invention relates to the technical field of printing graphite, in particular to a quick-drying printing ink for soft PVC and a preparation method. Background technique [0002] Soft PVC materials are more common in our lives, such as tablecloths, shower curtains, inflatable toys, etc. The printing of soft PVC materials is usually solvent-based products, and the solvents used in printing ink include ketones And esters, ketones such as acetone, cyclohexanone, etc.; esters include ethyl acetate, butyl acetate, etc. [0003] The advantages of the above-mentioned solvent-based printing ink are that the drying speed is relatively fast and the production time is short, but there is a disadvantage that the solvent used will volatilize into the atmosphere and cause environmental pollution. In order to solve this disadvantage, the existing technology has developed pure water-based printing ink, that is, using pure water as a solvent, the problem of pollutio...
