Abstract
The invention discloses a process for preparing an antistatic modified PET release film. The process for preparing the antistatic modified PET release film is characterized by comprising the following steps: (1) coating a base film layer with an ethyl silicate coating to form an antistatic coating; (2) preparing the following components into a sizing agent in parts by weight: 15-50 parts of conductive polymer resin, 15-50 parts of hydrogen-containing silicone oil, 20-55 parts of vinyl silicone resin, 0.1-2.0 parts of an initiator, 0.05-1.0 part of an antioxidant and 0.1-1 part of calcium stearate, and uniformly coating the upper surface of the anti-static coating with the sizing agent so as to form a functional layer at a time; and (3) performing thermocuring and photocuring on the coated base film, thereby obtaining the product, wherein the thermocuring temperature is 80-120 DEG C and the thermocuring time is 10-30 seconds; and the photocuring intensity is 80-120W/cm, the dosage is 100-400J/cm<2> and the irradiation time is 5-20 seconds. The antistatic coating formed by ethyl silicate has high conductivity, and static electricity on the surface of the release film can be taken away, so that an effect of removing the static electricity is achieved, and the coating is very stable and excellent in static electricity removing effect.
Description
Technical field
The present invention relates to a kind of preparation technology of antistatic modified PET release film.
Background technology
PET release film is exactly take PET film as base material, and is coated with last layer silicone oil on the surface of PET film, makes the surface of PET film sliding, to reduce the tension force on PET film surface.Reach release effect.
PET release film is a kind of material that hot transfer printing is commonly used, and ground is PET, forms so be also silicon oil membrane through coating silicone oil.General thickness is from 25um to 150um.Have cold and hot to tear with light mute point, through anti-electrostatic and anti-scratch process, product has good adsorptivity and stickiness.
The industry fields such as PET release film now extensively should be packed, print, silk-screen, bat printing, inscription plate, thin film switch, flexible circuitry, insulated product, wiring board, laser anti-counterfeit, laminating, electronics, sealing material use film, light reflecting material, water-proof material, medicine (plaster paper using), sanitary paper, adhesive article, the processing of cross cutting stamp.
But existing release film antistatic property is poor, therefore, the product that a kind of antistatic property of exploitation is good is needed badly.
Summary of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, provides a kind of preparation technology of antistatic modified PET release film.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
The preparation technology of a kind of antistatic modified PET release film of the present invention, is characterized in that, comprise the following steps:
