Curling-resisting heat sublimation transfer printing film

Abstract

The invention discloses a curling-resisting heat sublimation transfer printing film. The curling-resisting heat sublimation transfer printing film comprises a base film, the front face of the base film is coated with a first coating, the rear face of the base film is coated with a second coating, and the first coating comprises, by weight, 2 parts to 10 parts of starch, 10 parts to 20 parts of cellulose, 2 parts to 8 parts of polyvinyl alcohol, 4 parts to 12 parts of glycerinum, 8 parts to 15 parts of silicon dioxide, 8 parts to 16 parts of barium sulfate, 7 parts to 20 parts of aluminum oxide, 8 parts to 18 parts of titanium dioxide, 10 parts to 25 parts of calcium carbonate and 4 parts to 15 parts of polyvinyl chloride resin; the second coating comprises, by weight, 10 parts to 20 parts of starch, 10 parts to 18 parts of titanium dioxide, 4 parts to 10 parts of bentonite powder and 1 part to 4 parts of nano-silver ion powder. The preparing technology is novel, the preparing process is environment-friendly and free of pollution, the prepared transfer printing film is high in curling-resisting performance, and the transferring efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of thermal sublimation transfer film preparation, in particular to an anti-curling thermal sublimation transfer film. Background technique [0002] Thermal transfer film is a medium material of thermal transfer process; thermal transfer process is a process of transferring the decorative pattern on the thermal transfer film to the substrate through one-time heating of the thermal transfer film to form a high-quality decorative film , the existing thermal sublimation transfer film is generally only coated with coating material on one side, which is likely to cause bending deformation of the base film and affect the quality of thermal transfer printing. Contents of the invention [0003] The object of the present invention is to provide an anti-curl thermal sublimation transfer film to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the ...
