Problems solved by technology

The production process in which matteness and color are achieved through the pre-coloring process and the post-coloring process has the following disadvantages: (1) The production process of the two coloring processes will increase the probability of scrapping the transfer film. If the front coloring or post-coloring If there is a major defect in any of the processes (for example, the matteness is not enough, or the color accuracy is not good enough), it will lead to the scrapping of the transfer film; It will lead to low production efficiency and increase production cost. On the other hand, it will easily lead to unstable product quality; (3) The production process that the matteness and color are realized through the pre-coloring process and the post-coloring process respectively, the products produced The appearance color is not strong enough, and the high-end feeling is not enough

Abstract

The invention relates to the technical field of transfer membranes, in particular to a color-staining process and a preparation method of a PET (polyethylene terephthalate) transfer membrane. The color-staining process of the PET transfer membrane comprises the steps of firstly, adding matt powder into resin and stirring uniformly to obtain primary matt coating; secondly, grinding the primary matt coating until the primary matt coating is changed to be a milk white state from a semi-transparent state, thereby obtaining secondary matt coating; thirdly, adding organic solvent and pigment powder into the secondary matt coating and stirring uniformly to obtain mixed color-staining coating; fourthly, coating the mixed color-staining coating onto a PET base membrane and drying, so as to form a matt color layer on the surface of the PET base membrane. According to the color-staining process of the PET transfer membrane, the production procedures can be reduced, the production efficiency is improved, the scrap rate of the transfer membranes is reduced and the production cost is reduced; the products have good matt effect, rich and mellow color and luster and good color accuracy.

Description

Technical field [0001] The invention involves the field of metastasis technology, which specifically involves the color process of a PET metastatic membrane and the preparation method of PET metastatic membrane. Background technique [0002] PET metastasis membrane is widely used in packaging paper. This type of packaging paper is mostly used for high -end packaging box boxes, high -end cigarette packaging boxes, membranes, medicines and cosmetics packaging.The PET metastasis film is made of coloring process, vacuum -plating and back -painted solids on the PET base film.The application process of PET metastasis is to transfer aluminum layers, colors to paper, leather, textiles and other substrates through heating and pressurizing methods, thereby changing the appearance and quality of the substrateDiversity, there are gold, silver, red, blue, green, purple, black, brown and other colors. [0003] In order to make the appearance of the product more beautiful, the appearance of the...
