Abstract

The invention discloses a transparent PET antistatic release film which comprises a PET release layer, a PU glue layer and a PET transparent film surface layer, wherein the PET release layer, the PU glue layer and the PET transparent film surface layer are sequentially overlapped from bottom to top; the PU glue layer consists of the following raw materials in parts by mass: 55-75 parts of polyurethane resin, 5-8 parts of solvent, 20-30 parts of curing agent, 11-15 parts of antistatic agent, 5-8 parts of high-temperature filler, 4-5 parts of plasticizer and 3-4 parts of antioxidant. The PU glue layer is prepared from the formula disclosed by the invention; the product has the advantages of high static resistance value, perfect antistatic property, low peel strength, relatively low viscosity and easiness in peeling; moreover, the product also has relatively good self-exhaust property and is easily pasted while the weather resistance is good and residue is avoided after peeling; and when in use, a hole is formed in the PET transparent film surface layer 30, and a precision component is put in the hole and stuck by the PU glue layer to replace a circuit board tray.

Description

technical field [0001] The invention relates to the technology in the field of release films, in particular to a transparent PET antistatic release film. Background technique [0002] The release film refers to a film whose surface can be distinguished. The release film is not sticky or slightly sticky after contacting with a specific material under limited conditions. Release film is used in electronics, automotive foam, printing and other fields. Most of its application range is with sticky ones, especially tape products. However, the current release film cannot be used in the field of circuit board production and production due to its relatively high peeling force and poor antistatic performance. Contents of the invention [0003] In view of this, the present invention aims at the shortcomings of the prior art, and its main purpose is to provide a transparent PET antistatic release film, which can effectively solve the problems of the existing release film with high pe...
