Problems solved by technology

[0003] At present, the existing products on the market generally have problems such as poor water resistance, fast fading, easy peeling off of the layer, and blurred images; printed products have a short storage time and need to be replaced frequently, resulting in a large degree of waste and not conducive to environmental protection; when customers use Generally, film coating is required after printing indoors and outdoors, which invisibly increases labor costs; in addition, how to improve printing clarity and color vividness while improving water resistance and scratch resistance has always been a problem that plagues the industry.

Embodiment 1

[0028] The material formula of the ink-absorbing layer is: 30 parts of 3-9 μm precipitated silica, 15 parts of 10-20 μm precipitated silica, 2 parts of polycarboxylate sodium salt ink-absorbing pigment dispersant, 10 parts of 2699 polyvinyl alcohol, vinyl acetate 30 parts of ester-ethylene copolymer, n 1 = 3, n 2 =10, 5 parts of amphoteric star-shaped polymers of R=CH2Cl, 8 parts of epichlorohydrin dimethylamine polymer color fixing agents and 15 parts of water;

[0029] The preparation process of the ink-absorbing layer material is as follows: add deionized water into the dispersion tank, turn the mixer to add the ink-absorbing pigment dispersant, increase the rotation speed to 800RPM, disperse for 10-20min, and increase the rotation speed to 2500RPM-3000RPM after adding the ink-absorbing pigment. Continue to disperse for 20-30 minutes, filter the dispersion liquid into the mixing tank and add polymer color fixing agent, surfactant and other additives, then add resin, contin...

Embodiment 2

[0032] The formula of the ink-absorbing layer material is: 30 parts of 3-9 μm precipitated silica, 15 parts of 10-20 μm silica, 2 parts of polycarboxylate sodium salt dispersant, 10 parts of 2099 polyvinyl alcohol, 30 parts of vinyl acetate-ethylene copolymer copies, n 1 = 4, n 2 =10, R=CH 2 CH 2 8 parts of COOH amphoteric star polymer, 8 parts of epichlorohydrin dimethylamine polymer fixing agent and 15 parts of water;

[0033] The ink-absorbing layer material preparation process of embodiment 2 is the same as embodiment 1;

[0034] The printing medium production process of Example 2: Corona is carried out on PVC, and the corona dyne value reaches 40-42. Use a scraper to coat a 15 μm acrylic resin primer on the substrate, and after drying in an oven at 90-100 ° C, continue Use a scraper to coat a 30μm ink-absorbing layer on the primer layer and dry it in an oven at 80-110°C.

Embodiment 3

[0036] The material formula of the ink-absorbing layer is: 30 parts of 3-9 μm precipitated silica, 15 parts of 10-20 μm silica, 2 parts of polycarboxylate sodium salt dispersant, 10 parts of 2499 polyvinyl alcohol, 25 parts of polyurethane resin, n 1 =5,n 2 =12, R=C 5 h 11 NH 2 10 parts of amphoteric star polymers, 8 parts of epichlorohydrin dimethylamine polymer fixing agent and 15 parts of water;

[0037] The preparation method of the ink-absorbing layer material is: add deionized water into the dispersion tank, turn the mixer to add sodium salt dispersant, increase the speed to 800RPM to disperse for 10-20min, add two kinds of silica pigments, increase the speed to 2500-3000RPM and continue to disperse for 20 minutes. ~30min, filter into the mixing tank, slow down and stir, add epichlorohydrin dimethylamine polymer color fixing agent, surfactant and other additives, add polyurethane resin, star polymer resin, continue to stir at 200~300RPM for 30min ;

Abstract

The invention discloses a water-based color ink-jet printing medium and a production method thereof. The water-based color ink-jet printing medium comprises a base material, wherein the base material is already subjected to corona treatment, at least one surface of the base material is coated with a base layer and an ink absorption layer, and the ink absorption layer contains an amphoteric star polymer. The water-based color ink-jet printing medium disclosed by the invention can be used for effectively improving the interaction of dye and pigment molecules which are contained in the ink absorption layer and ink, increasing the cohesive force of the ink absorption layer and enhancing the printing color density and the water resistant property by applying the amphoteric star polymer to a color ink-jet printing medium.

Description

【Technical field】 [0001] The invention relates to a water-based color inkjet printing medium and a production method thereof, belonging to the technical field of printing medium. 【Background technique】 [0002] With the advancement of modern science and technology, digital technology has developed rapidly in today's world. What follows is the rapid development of personalized advertising media, indoor decoration, high-end artwork, cultural and educational photocopying and other special printing products. Inkjet printers have gradually become the main choice of products in the above-mentioned markets due to their low price, high image quality, and fast output speed.
