Problems solved by technology

[0005] (1) The surface is often not smooth enough, so that the pattern layer printed on it is not clear and smooth, which also affects the accuracy of the transfer film, and has a negative impact on the transfer accuracy and aesthetics;
[0006] (2) The coating thickness of the hydrosol layer is unreasonable, resulting in the lack of high gloss and three-dimensionality of the printed pattern;
[0007] (3) The dissolution rate of the hydrosol layer in water is too slow, resulting in unsmooth release of the film and affecting the transfer effect of the pattern;
[0008] (4) The water absorption of each part of the water transfer paper is uneven, which affects the uniform smoothness of the rubber surface and the release effect, resulting in an unsatisfactory transfer effect

Abstract

The invention discloses water transfer printing paper and a preparation method thereof. The water transfer printing paper comprises a hydrosol layer, a film-forming adhesive layer, carrier backing paper and an opposite colloid layer sequentially from top to bottom, wherein the opposite colloid layer is a starch layer; the film-forming adhesive layer comprises an activity colloid layer and a white colloid layer sequentially from top to bottom; the activity colloid layer is obtained by coating and drying a mixed aqueous solution of a brightening agent and the starch; the mass fractions of the brightening agent and the starch are respectively 0.5%-1% and 35%-45%; and the white colloid layer is a starch layer. The hydrosol layer is obtained by coating and drying a mixed aqueous solution of kaolin, a butylbenzene emulsion, a dispersing agent and polyvinyl alcohol; and the mass fractions of the kaolin, the butylbenzene emulsion, the dispersing agent and the polyvinyl alcohol are respectively 40%-50%, 10%-15%, 1%-3% and 3%-5%. The water transfer printing paper disclosed by the invention has the advantages of a smooth and flat surface, rational thickness of coated glue layers, higher de-molding speed, uniform water absorbability, and uniform and smooth glue surface.

Description

technical field [0001] The invention relates to a printing paper, in particular to a water transfer printing paper and a preparation method thereof. Background technique [0002] Water transfer printing paper is also called small film bottom paper, which is the transfer material used as an intermediate carrier in the water transfer printing process. Water transfer printing paper is a special polymer material, generally composed of three layers, the bottom layer is the carrier backing paper layer, the middle layer is a film-forming adhesive layer, and the upper layer is a hydrosol layer. [0003] When in use, the inkjet printer is usually used to spray dye to print the required color pattern on the transfer paper. When it meets water, the hydrosol layer will automatically dissolve, so that the color material and the transfer paper will be separated, and the transfer of graphics and text will be realized. [0004] At present, the existing water transfer paper generally has th...
