A kind of manufacturing process of fluorine release film

Abstract

The invention discloses a manufacturing process of a fluorine element release film, which comprises the following steps: 1) preparing a coating, that is, mixing a fluorine element coating main agent with a n-heptane solvent according to a ratio of 1:6-1:8, adding a bridging agent and an anchoring agent, then adding a catalyst and stirring; 2) preparing the fluorine element release film, that is, coating the above coating on a PET raw film in a precise coating manner, performing an curing reaction in an oven, then cooling and rolling to obtain the finished product. The PET film used in the invention is strict in material selection criterion; the selected main material is available on the market; the blending and preparation steps of the coating solution are strict; a precise coating mode is adopted to allow the coating of the whole film to be quite uniform; after curing and drying, the release force of the product is very stable; the product is good in aging resistance, is very suitable for all organic silica gel protection adhesive tapes, and can be used in high-temperature high-humidity environment with good isolation effect.

Description

technical field

[0001] The invention relates to a novel release type isolation material of a silicone belt, in particular to a manufacturing process of a fluorine release film. Background technique

[0002] At present, silicone release paper (membrane) is commonly used in the market, and silicone is used as a release agent. Therefore, silicone release paper (membrane) cannot be used as an isolation material on a silicone tape, because they belong to silicon series, usually such materials are imported from Japan, Taiwan, etc., which is not conducive to the development of our country in this field. According to Taiwan's Industrial Technology Research Institute, due to the rapid development of LED and OLED displays, touch-screen mobile phones, and large electronic blackboards, they are used in the production process, process transfer protection, product shipment surface protection, instrumentation surface protection, and high-temperature welding. Silicone tapes are widely used...
