A kind of anti-static release film

Technical field

The utility model belongs to a kind of mould release membrance, particularly a kind of anti-static release film that is applied to the electronics industry cross cutting, covers, protects industry.

Background technology

Along with the development of industries such as LCD, LED, PC, mobile phone, the demand of mould release membrance is grown with each passing day, and require more and more highlyer, one of them requires mould release membrance to possess anlistatig function exactly.Common mould release membrance is because self base material is a polyester material, belong to insulator, in rolling with unreel and be easy to generate static in the process, static gently then can cause adsorbing dust, influence the post-production quality, heavy then can cause with it that the contacting electronic components and parts are damaged by electrion.

On traditional coating process of mould release membrance, antistatic coating and release coating are inconsistent, have only simple antistatic film or simple release film in the market, do not possess the release film of anti-static function and release function simultaneously.

The utility model content

The purpose of this utility model is to provide a kind of anti-static release film that possesses anti-static function and release function simultaneously.

The technical solution that realizes the utility model purpose is: a kind of anti-static release film comprises three layers: ground floor is a base material, and main component is PET (PETG); The second layer is a conductive coating, and main component is to contain ∏ such as polythiophene and the polyaniline electroconductive polymer compound of rail macromolecule structure altogether; The 3rd layer is the mould release coating, and main component is the add-on type organosilicon material.

The utility model compared with prior art, its remarkable advantage is: solved antistatic coating and the inconsistent problem of release coating in the coating process of existing mould release membrance, product possesses anti-static function and release function simultaneously.

Below in conjunction with accompanying drawing the utility model is described in further detail.
