Abstract

The invention discloses water transfer paper and a preparation method thereof. The water transfer paper comprises a back coating layer, base paper, a prime coating layer, a water-soluble coating layerand a waterproof coating layer which are distributed layer by layer. Coating of the back coating layer comprises 8-15 parts by weight of a bacterial cellulose wet film; 0.08-0.15 part by weight of hydrogen peroxide, 0.1-0.2 part by weight of sodium hydroxide and 30-40 parts by weight of water, and is prepared by shearing and dispersing at 70-90 DEG C in a high-speed dispersion machine for 30-45 min, adding 40-60 parts by weight of water for dilution, and then sieving the mixture to obtain the back coating, with the solid content of the coating being 2-5%. According to the prepared water transfer paper, on the premise that the water permeation speed of the paper is guaranteed, the back face is coated with the bacterial cellulose glue solution, and the water transfer paper which is stable in size, high in demolding speed and excellent in printing and transferring effect is prepared.

Description

technical field

[0001] The invention relates to the technical field of papermaking processing, in particular to water transfer printing paper and a preparation method thereof. Background technique

[0002] Water transfer printing paper is a special paper produced with the development and application of water transfer printing technology. The biggest feature of water transfer printing is that it is suitable for concave-convex three-dimensional curved surface printing, which makes up for the traditional printing technology's requirement that the substrate be flat or nearly flat, and the printing effect is realistic. Therefore, it is the preferred printing method for porcelain, glassware, plastic products, nameplates, etc.

[0003] The water transfer printing technology prints the pattern on the base paper coated with a layer of soluble adhesive film on the surface, and the adhesive film is separated from the base paper by soaking in water on the back, and the pattern is trans...
