Embodiment 1

[0030] Example 1 Preparation of environmentally friendly degradable high-definition digital printing water transfer paper

[0031] Primer coating preparation: apply 70 parts of GCC (ground calcium carbonate), 0.3 parts of sodium polycarboxylate dispersant, disperser at low speed 1500r / min, then add 30 parts of china clay, increase the speed to 3000 rpm, and disperse for 20 minutes. Reduce the dispersion speed, slowly add 0.2 parts of CMC (sodium carboxymethyl cellulose), and then disperse at high speed for 20 minutes, reduce the dispersion speed, add 25 parts of acrylic latex latex, disperse for 10 minutes, add 0.6 parts of lubricant, 1 part of water-resistant agent to disperse After 10 minutes, add sodium hydroxide to adjust the pH value to 8.5, disperse at a low speed for 10 minutes, and stop the machine.

[0032] Surface coating preparation: use a powder kneader to knead and mix 10 parts of corn starch and 10 parts of wood-plastic potato starch until uniform; add 65.5 parts...

Abstract

The invention discloses environmentally-friendly, degradable and high-definition digital printing water transfer paper. The water transfer paper comprises a base coating and a top coating, wherein the formula of the base coating comprises 60-90 parts of coating GCC, 10-40 parts of porcelain clay, 0.2-0.6 part of sodium polycarboxylic acid dispersing agent, 0.2-0.6 part of CMC (carboxymethylcellulose), 15-40 parts of latex, 1.0-2.0 parts of water repellent agent, 0.6-1.5 parts of lubricant, and proper amount of sodium hydroxide; the formula of the top coating comprises 2-6 parts of CMC, 10-20 parts of maize starch, 10-20 parts of cassava starch, 10-15 parts of PVA (Polyvinyl Acetate), 0.5-1 part of nanosilicon dioxide, 1-5 parts of PCC (Precipitated Calcium Carbonate), and 33-66.5 parts of water. Compared with the prior art, the water transfer paper has the advantages of being good in printing effect, high in environmental protection performance, fast in film forming and die releasing speed, and free from glue layer on a pattern during transfer printing, so that the pattern on a transfer-printed article is clean and bright, bright in color, and high in restoration performance.

Description

technical field [0001] The invention relates to the technical field of transfer printing of various decorative patterns, in particular to an environmentally friendly degradable high-definition digital printing water transfer paper and a preparation method thereof. Background technique [0002] Water transfer printing technology is a new fast and efficient personalized printing technology. It uses ordinary color inkjet printers to directly print patterns on water transfer paper and then perform water transfer printing. It does not require special equipment and is not limited by media. High temperature heating is required; the base material of the water transfer paper has a very high expansion rate, and it is easy to be tightly attached to the surface of the object, and the printing cost can be greatly reduced. It can print 4 to 8 colors at a time, and the overprinting accuracy is high. Perfect It solves the requirements of high printing requirements, rich decorative colors an...
