Problems solved by technology

[0003] At present, the release film generally only has the function of isolating the protective adhesive layer, and does not have 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 printing, printing, and water pen writing at the same time.

Embodiment 1

[0027] The present embodiment provides a printable and writable film material, and its preparation method is as follows:

[0028] 1. Preparation of coating solution: Dissolve non-silicon release agent poly(N-octadecyl vinyl carbamate) in a mixed solvent composed of 80% toluene and 20% ethyl acetate, heat up to 50-60 °C and Insulation; then add 5wt% of additives, wherein the additives include glycidyl acrylate 35%, sodium lauryl aminopropionate 50%, fluorine-containing prepolymer perfluorobutyl ethyl acrylate 14%, 2, 6-di-tert-butyl-4-methylphenol 0.7%, 2-amino-3-methylphenol 0.3%. After mixing the components evenly, a coating solution was obtained, and the solid content of the coating solution was adjusted to 0.5%.

[0029] 2. Coating: The prepared coating liquid is coated on the PET substrate by the micro-gravure coating process. The temperature is controlled at 50-60°C and the coating weight is 0.08g / cm. 2 ; After the coating is completed, it is sent to a 50°C holding room...

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...
