Problems solved by technology

[0003] With the development of technology, OLED, as a high-end screen, has gradually become the mainstream of the market, and the requirements for related die-cut products have also gradually increased. Ultra-light peeling force is required to adapt to high-speed production, and higher antistatic ability is required to prevent static electricity. Due to the adsorption of particles and dust in the air, the release films currently on the market cannot meet the standard of ultra-light release films, and the peeling force of the release film after high temperature aging is not stable; or even if the release force is low, The antistatic effect of the release film is not good

Abstract

The invention discloses a production process of a double-sided antistatic ultralight release film. The production process comprises the following steps: S1, preparing antistatic coating liquid and release agent coating liquid; S2, coating two surfaces of a base film layer with the antistatic coating liquid, and curing for the first time to obtain a film with two antistatic layers; S3, coating the release agent coating liquid on the surface of at least one antistatic layer, and curing for the second time to obtain a release film semi-finished product; and S4, curing the release film semi-finished product to prepare the double-sided antistatic ultralight release film. The release agent coating liquid is mainly composed of main agent release silicone oil, a cross-linking agent, an anchoring agent, a platinum catalyst, an anti-sticking agent, an inhibitor, a silane coupling agent and a solvent. According to the production process, the adhesive force is further improved through the silane coupling agent and secondary curing, the thickness of the release layer is increased, and the release film with ultralight release force and good release force high-temperature stability is obtained; and the antistatic function of the antistatic layer is also improved by the first-time curing. The invention further discloses the release film.

Description

Technical field [0001] Technical Field The present invention relates to a thin film material, particularly relates to a process for the production of double-sided release film antistatic lightweight and release film. Background technique [0002] The release film is a die-cutting process consumables must be used, the release film surface adhesive bonding and die bonding article, a release film and the protective functions integrally die-cut plastic product is supported in the die-cut products throughout the production process acting sticky surface, and easy to transport. [0003] With the development of technology, OLED screens become mainstream as the high-end market, the requirements of the relevant die-cutting products have gradually improved, ultra-light peel force required to accommodate high-speed production, requiring higher antistatic ability to prevent static electricity and stripes adsorption of dust particles in the air, from the film currently on the market can not re...
