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] This embodiment provides a printable and writable film material, the preparation method of which is as follows:

[0028] 1. Prepare the coating solution: dissolve the 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% additives, wherein additives include glycidyl acrylate 35%, sodium laurylalanine 50%, fluorine-containing prepolymer perfluorobutyl ethyl acrylate 14%, 2, 0.7% of 6-di-tert-butyl-4-methylphenol, 0.3% of 2-amino-3-methylphenol. After uniformly mixing each component, a coating liquid is obtained, and the solid content of the coating liquid is adjusted to 0.5%.

[0029] 2. Coating: The prepared coating solution is coated on the PET substrate by using the micro-recessed coating process, and the coating temperature is controlled at 50-60°C, and the coating amount is 0.08g / cm 2 ; After the coating is completed, it is sent to a heat preser...

Abstract

The invention discloses a printable and writable release agent, a film material and a preparation method thereof. The printable and writable release agent comprises a non-silicon release agent and anassistant added into the non-silicon release agent, and the additive amount of the assistant is 5-10 wt% of the non-silicon release agent; wherein the auxiliary agent comprises 35-45 wt% of an amphiphilic surfactant containing hydroxyl, 40-50 wt% of an amphiphilic surfactant containing amino, 10-15 wt% of a fluorine-containing prepolymer, 0.5-0.8 wt% of 2,6-di-tert-butyl-4-methylphenol and 0.3-0.5wt% of 2-amino-3-methylphenol. The printable and writable release agent disclosed by the invention has the functions of printing, printing and writing with a fountain pen at the same time, and effectively solves the problem of adhesion of oily and water-based ink to a release layer at the same time.

Description

technical field [0001] The invention relates to the technical field of release materials, in particular to a printable and writable release agent, a printable and writable film made of the release agent, and a preparation method for the film. Background technique [0002] Release agent, also known as anti-sticking agent and release agent, is one of the key materials for the production of pressure-sensitive adhesive tape and self-adhesive products, and its performance directly affects the quality of pressure-sensitive adhesive tape and self-adhesive products. Classified 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 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 ha...
