Problems solved by technology

Among them, water-based dye ink will quickly decompose and volatilize under ultraviolet light, so it is not suitable for outdoor use; while water-based pigment ink has the characteristics of good sun resistance, but due to the pigment particles and polyvinyl chloride used outdoors, etc. There is no chemical bond between non-absorbing printing media to form a strong molecular force, so that the pigment particles cannot be well attached to the substrate, resulting in poor friction resistance of the finished product after printing. In addition, since non-absorbing printing media such as polyvinyl chloride are low Non-porous materials with surface tension prevent water-based pigment inks from spreading and drying directly on non-absorbent printing media such as polyvinyl chloride, which in turn leads to poor printing performance when water-based pigment inks are used to print on non-absorbent printing media such as polyvinyl chloride. Unsatisfactory print

Embodiment 3

[0027] A primer liquid suitable for printing non-absorbent printing media with water-based pigment inkjet ink, which is made of the following components by weight percentage: nano-titanium dioxide: 50%, polyvinylpyrrolidone: 10%, cationic polyurethane resin emulsion: 15%, trimethylcetylammonium hydroxide: 6%, Dow X-405: 0.1%, Surfynol DF-110L: 0.1%, ProxelGXL: 0.3%, deionized water: the balance. The preparation process of the primer solution is similar to that of Example 1, and will not be repeated here.

[0028] After the primer solution prepared in this example is evenly applied to the polyurethane substrate by wiping, it is dried under microwave for 3 minutes, and then any water-based pigment ink commonly used in the art can be used to coat the primer solution on the polyurethane substrate. The finished product is obtained after inkjet printing on a layer of polyurethane substrate and drying.

Abstract

The invention discloses a prime coating liquid suitable for an aqueous pigment ink-jet-printing ink printed non-absorptive printing medium. The prime coating liquid comprises following components in percentage by weight: 10 to 70% of a pigment adsorbent, 5 to 15% of a highly swelling polymer, 5 to 25% of cationic emulsion polymer, 2 to 15% of a color fixing agent, 0.05 to 1% of a base material wetting agent, 0.05 to 1% of an anti-foaming agent, 0.1 to 1% of a sterilizing agent, and the balance being deionized water. Moreover, the invention also discloses a preparation method of the prime coating liquid and a method of applying the prime coating liquid on a non-absorptive printing medium. The provided prime coating liquid is applied on a non-absorptive printing medium and can effectively improve the ink absorbing performance, color fixing performance and binding force of an aqueous pigment ink on a non-absorptive printing medium such as polyvinyl chloride.

Description

technical field [0001] The invention relates to the technical field of ink-jet printing media, in particular to a primer liquid suitable for printing non-absorbing printing media with water-based pigment ink-jet ink and its preparation method and application. Background technique [0002] With the rapid development of the inkjet ink market, in the field of digital inkjet printing, the inkjet inks currently used include solvent-based inks, UV light-curable inks and water-based inks. Among them, with the increasing calls for environmental protection, solvent-based inks have gradually withdrawn from the market due to environmental issues such as high VOCs volatilization; while UV light-curable inks have solved the problems of high VOCs and rapid curing, but there are monomers that have a large odor and are irritating. Strong, and the residual small molecule photoinitiator fragments after curing are easy to migrate to the surface of the cured film and cause pollution; while wate...
