Problems solved by technology

In the second stage, the membrane begins to unfold, not only unfolding the original curled part, but also continuously stretching and becoming larger, and finally enters the third stage: the dissolution stage. In the third stage, the membrane is continuously dissolved until it is completely dissolved in water, and now Excessive curling and unfolding of the water transfer film in the prior art in the first and second stages affects the transfer effect, especially the different deformations of the graphics in different directions after transfer

Embodiment approach 1

[0073] Embodiment 1, comprising the nonionic surfactant of the following structure of the PVA resin of 100 parts by weight, the plasticizer of 20-40 parts by weight, the starch of 5-10 parts by weight and 5-15 parts by weight:

[0074]

[0075]The R 1 , R 2 , R 3 , R 4 Independently denoted as -CH 2 CH 2 —, x, y, z, m are integers greater than or equal to 1, x+y+z+m=10-30, and X is a monovalent alkyl group with 12-26 carbon atoms;

[0076] The plasticizer is selected from one or more of glycerin, diglycerin, trimethylolpropane, mannitol, sorbitol, and pentaerythritol.

Embodiment approach 2

[0077] Embodiment 2 is the same as Embodiment 1, except that the plasticizer is a mixture of glycerol and sorbitol, and the mass ratio of glycerol and sorbitol is 1:0.1-0.5.

Embodiment approach 3

[0078] Embodiment 3 is the same as Embodiment 1 or 2, except that the degree of polymerization of PVA is 500-1200, and the degree of saponification is 91-97%.

Abstract

The invention relates to a water transfer membrane, which comprises the following components in parts by weight: 100 parts of PVA resin, 20 to 40 parts of plasticizer, 5 to 10 parts of starch, and 5 to 15 parts of nonionic surfactant. The provided water transfer membrane has a very good transfer printing effect.

Description

technical field [0001] The present invention relates to water transfer printing films, in particular to International Patent Classification No. B41M5 / 00, sheet material for printing. Background technique [0002] As early as 1931, George Thorne of Liverpool, England, invented a curved surface printing method: hydraulic printing, the principle of which is: install a material tank containing ink above a water tank full of water, and the outlet of the material tank is facing the water surface When printing, first open the discharge port, and form a certain pattern on the water surface through the horizontal movement of the material tank, and then press the substrate into the water, and use the pressure of the water to make the ink with a certain pattern floating on the water surface stick to it. It is attached to the surface of the substrate to complete the printing. The above method can be used to print objects with curved surfaces and uneven surfaces, which is very innovative...
