preparation example Construction

[0032] The second aspect of the present invention provides a method for preparing a fluorine release film. The present invention has no special restrictions on the coating equipment, and a coating production line well known to those skilled in the art can be used, including the following steps:

[0033] S1. Coating the antistatic coating on the base material, solidifying and cooling to obtain the antistatic coating.

[0034] S2. Coating the fluorine release coating on the antistatic coating, curing, cooling and winding to obtain a fluorine release film.

[0035] The preparation method provided by the invention is simple and easy to control, has mild conditions and low raw material cost, and is suitable for large-scale industrial production and application.

[0036] The raw materials used in the present invention are all commercially available.

Embodiment 1

[0040] Embodiment 1 provides a fluorine release film, including a PET substrate layer, an antistatic coating, and a fluorine release coating. The antistatic coating and the fluorine release coating are formed by coating the antistatic coating and the fluorine release coating respectively.

[0041] The preparation method of the antistatic coating is: take 3.5kg of water-soluble acrylic resin (purchased from Foshan Byton New Material Co., Ltd., model BD-8334) and dissolve it in 6.065kg of deionized water, and add 0.4kg of adhesive Antistatic agent (purchased from Shandong Juli Antistatic Technology Co., Ltd.), 15g of nano-TiO 2 (purchased from Ningbo Jiwei Nano New Material Technology Co., Ltd., model MZT-A1, average particle size 3 ~ 5nm), and finally add 20g of dimethylethanolamine (purchased from Jinan Chuangshi Chemical Co., Ltd.) and stir evenly to obtain the anti- Static paint.

[0042] The preparation method of the fluorine-based release coating is as follows: firstly, ...

Embodiment 2

[0047] Similar to Example 1, a fluorine release film and its preparation method are provided, but in the preparation method of the antistatic coating, the water-soluble acrylic resin is 3kg, the deionized water is , the adhesive antistatic agent is 0.3kg, Nano TiO 2 10g, 10g of dimethylethanolamine, and 6.68kg of deionized water.

Abstract

The invention provides a fluorine release film and a preparation method thereof. The fluorine release film comprises a base material layer, an antistatic coating and a fluorine release coating, wherein the antistatic coating and the fluorine release coating are respectively formed by coating an antistatic coating material and a fluorine release coating material. According to the invention, the binding force among the base material layer, the antistatic coating and the fluorine release coating is high, and the fluorine release film has good release force and high-temperature release force whilemaintaining the excellent properties of PET.

Description

technical field [0001] The invention belongs to the technical field of release films, and in particular relates to a fluorine release film and a preparation method thereof. Background technique [0002] The release film has no stickiness or slight stickiness after contact with specific materials under limited conditions. Usually, in order to increase the release force of the plastic film, a release agent is coated on the surface of the film, so that it can exhibit extremely light and stable release force for various pressure-sensitive adhesives. For the release film of PET substrate, due to the high resistivity of PET, it is easy to generate static electricity, which limits its application in the electrical and electronic industries. In addition, with the development of 5G, especially in recent years, the widespread use of curved screens for electronic equipment requires a fluorine release film with better performance as a support, which requires higher and higher performan...
