Abstract

The invention belongs to the technical field of PET (Polyethylene Terephthalate) transfer films, and particularly relates to a preparation process of a micro-porous hydrolysis-resistant PET transfer film. In order to solve the problem that a PET transfer film in the prior art is not hydrolysis-resistant and is poor in coloring and toughness, the following scheme is provided, namely, the method comprises the following process steps of: S1, preparing raw materials: a PET base film, a mixed solution of a DMF system, a hydrolysis stabilizer, a coloring agent component and a flexibilizer component; S2, firstly preparing the mixed solution of the DMF system, and the hydrolysis stabilizer; and S3, mixing the mixed solution of the DMF system with the hydrolysis stabilizer, and coating the surface of the PET base film with the mixed solution by using a coating machine. According to the invention, the mixed solution of the DMF system is prepared, so that the film has micro-pores; the hydrolysis stabilizer is added, so that the film is resistant to hydrolysis; and by additionally arranging a coloring layer and a toughness layer, the PET transfer film can be colored, the attractiveness is improved, and meanwhile the toughness can be improved.

Description

technical field [0001] The invention relates to the technical field of PET transfer film, in particular to a preparation process of a microporous hydrolysis-resistant PET transfer film. Background technique [0002] Transfer film is more and more widely used in the surface decoration industry of cloth. The cloth decorated with thermal transfer film can present colorful colors and exquisite patterns. In addition, the thermal transfer film can also be used for elastic fabrics, or to make the fabrics have special effects such as matt, pearlescent, laser, etc. The PET transfer film is based on PET film, and then the matte pre-coating, release layer, Coating of colored layers. [0003] The PET transfer film in the prior art has no hydrolysis resistance, and poor coloring and toughness. Contents of the invention [0004] The purpose of the present invention is to solve the disadvantages of PET transfer film in the prior art that it does not have hydrolysis resistance and poor ...
