Multipurpose laser transfer coating and preparation method thereof

Abstract

The invention discloses a multipurpose laser transfer coating and a preparation method thereof, and aims to solve the problems of inconvenience in processing and poor stability of a transfer coating.According to the technical scheme, the multipurpose laser transfer coating is characterized by comprising the following raw materials in parts by weight: 5-8 parts of cellulose acetate, 8-10 parts ofacrylic resin, 6-8 parts of propylene glycol monomethyl ether, 0.1-0.5 parts of leveling agent and 60-80 parts of a mixed solvent A, the multipurpose laser transfer coating disclosed by the inventioncan be conveniently and stably processed.

Description

technical field [0001] The invention relates to the technical field of gravure printing, more specifically, it relates to a multipurpose laser transfer coating and a preparation method thereof. Background technique [0002] Ordinary transfer coating, its function is to transfer and compound the aluminum layer on the film by vacuum aluminizing on the paper. In order to balance the good peelability and adhesion to the aluminized layer, the second coating is generally used; the first layer As a release layer, the coloring layer is required to have very good film-forming properties, good flexibility and scratch resistance, as well as low adhesion and good printability. The commonly used materials are mostly CAB (cellulose acetate butyrate), Nitrocellulose, polyacrylate resin, etc.; the second layer is the coloring layer, which requires good separation effect from the separation layer and good film formation, and the coloring layer and separation layer are firmly combined to form...

AI Technical Summary

Problems solved by technology

[0004] At present, there are many coating manufacturers at home and abroad to supply coatings, but due to the differences in the coating and molding machines used by each laser film manufacturer, the difference in ambient temperature and humidity will cause the coating to be used in the actual application process. There is great instability, such as high coating humidity, coating fog; if the resin absorbs moisture, there will be color aluminum layering; The fullness of the molded grating is unstable, showing impermeability or coating cracking, and high-temperature fogging. How to develop a coating suitable for different machines, different environments, and large production control intervals according to the actual environmental status and production conditions is to ensure An important prerequisite for product stability
