Embodiment 1

[0046] (1) Mix 70g PE and 0.1g polyether ester amide evenly, melt the particles, extrude with a single-screw screw extruder, and cold roll cold press to form resin layers on both sides of the base paper base. By controlling the temperature of the cold roll The degree of concavo-convexity is such that the surface roughness Ra of the obtained resin layer is 0.5.

[0047] (2) 15g of pearlescent pigments with a particle size of 5 microns, 15g of ethanol, 5g of surfactant, 5g of quaternary ammonium base acrylic acid copolymer emulsion, and 40g of polyvinyl alcohol solution (mass fraction is 10%) are added to the container and stirred evenly , to prepare pearlescent coating solution. Apply the above-mentioned pearlescent coating solution to the side of the resin layer obtained in step (1) away from the base paper base using a coating bar, and dry at a temperature of 100° C. for 3 minutes to obtain a pearlescent printing material.

Embodiment 2

[0049] (1) Mix 90g PP and 5g methyl methacrylate evenly, melt the particles, extrude with a single-screw extruder, and cold roll cold press to form resin layers on both sides of the base paper base. By controlling the temperature of the cold roll The degree of unevenness was such that the surface roughness Ra of the obtained resin layer was 2.0.

[0050] (2) 5g of pearlescent pigments with a particle size of 60 microns, 25g of ethanol, 3g of surfactant, 7g of polyvinylbenzyltrimethylammonium, and 20g of hydroxyethyl cellulose solution (mass fraction is 10%) are added to the container and stirred Evenly, prepare pearlescent coating solution. Apply the above-mentioned pearlescent coating solution to the side of the resin layer obtained in step (1) away from the base paper base using a coating bar, and dry at a temperature of 100° C. for 3 minutes to obtain a pearlescent printing material.

Embodiment 3

[0052] (1) Mix 98g PVA, 1g polyether amide imide and 2g polypyrrole evenly, melt, extrude from a single-bar screw extruder, cold roll cold press, form a resin layer on both sides of the base paper base respectively, pass The concavo-convex degree of the cold roll was controlled so that the surface roughness Ra of the obtained resin layer was 3.0.

[0053] (2) 25g of pearlescent pigments with a particle size of 30 microns, 35g of ethanol, 0.5g of surfactant, 2g of aminoalkyl polyglycol ether, 8g of polyvinylbenzyltrimethylammonium, and 60g of acrylic acid copolymer emulsion are added to the container in sequence Stir evenly in medium to prepare pearlescent coating solution. Use a coating rod to apply the above-mentioned pearlescent coating solution on the side of the resin layer obtained in step (1) away from the base paper base, and dry at a temperature of 100° C. for 3 minutes.

Abstract

The invention relates to a pearlescent printing material and a method for preparing the pearlescent printing material. The pearlescent printing material comprises a base paper base and resin layers located on both sides of the base paper base; the pearlescent printing material further comprises a pearlescent printing layer, and the pearlescent printing layer It is located on the side of the resin layer away from the base paper base. Thus, the pearlescent printing layers located on both sides of the base paper base are located on the resin layer, avoiding the direct contact between the different surfaces of the base paper base and the pearlescent printing layer, thereby preventing the The difference in roughness brings the problems of low printing image density of pearlescent printing materials and poor uniformity of pearlescent effect. Moreover, the present invention avoids the direct contact between the base paper base with strong water absorption and the pearlescent printing layer, and further avoids the adverse effect on the pearlescent printing material due to the strong water absorption of the base paper base. The pearlescent printing material of the present invention has high quality printing quality.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a pearlescent printing material and a method for preparing the pearlescent printing material. Background technique [0002] With the rapid development of digital fast printing and online e-commerce, personalized and customized printing images are becoming more and more popular. Compared with traditional printing methods, liquid electronic ink digital printing is more in line with the development trend of personalized customization due to its high-quality image quality and the characteristics of single-sheet printing and sheet-to-sheet printing. Compared with traditional ink, the particles of liquid electronic ink are small, so that it can achieve higher resolution and smoothness during printing, strengthen the sharpening of image edges, and the quality of printed images exceeds that of traditional printing. Pearlescent printing material is a product with unique appe...
