A printable and writable release agent, film material and preparation method thereof

Abstract

The invention discloses a printable and writable release agent, a film material and a preparation method thereof. The printable and writable release agent includes a non-silicon release agent and auxiliary materials added to the non-silicon release agent. agent, the addition of the auxiliary agent is 5-10wt% of the non-silicon release agent, and the auxiliary agent includes 35-45wt% of the amphiphilic surfactant containing the hydroxyl group and 40-50wt% of the amphiphilic surfactant containing the amino group. %, fluorine-containing prepolymer 10-15wt%, 2,6-di-tert-butyl-4-methylphenol 0.5-0.8wt%, 2-amino-3-methylphenol 0.3-0.5wt%. The printable and writable release agent of the present invention has the functions of printing, printing and writing with a water pen at the same time, and simultaneously effectively solves the problem of the adhesion of oily and water-based inks on the release layer.

Description

technical field

[0001] The invention relates to the technical field of release materials, in particular to a printable and writeable release agent, a printable and writable film material made of the release agent, and a preparation method of the film material. Background technique

[0002] Release agent, also known as release agent and release agent, is one of the key materials for the production of pressure-sensitive tapes and self-adhesive products. Its performance directly affects the quality of pressure-sensitive tapes and self-adhesive products. According to the main components of the release agent, it can be divided into: silicone release agent, non-silicon release agent, fluorine release agent.

[0003] At present, the release film generally can only play the function of isolating the protective adhesive layer, and has no other properties. Among them, only the non-silicon release agent coating has the function of pencil writing, but it does not have the functions of p...
