Description
Technical field
The present invention relates to a kind of mould release membrance, more particularly to a kind of BOPET matte releases film.
Background technology
Mould release membrance is also known as stripping film, barrier film etc., refers to that surface has the film of separation property, mould release membrance and specific material
Do not have sticky or slight viscosity after contacting under the limited conditions.The product of mould release membrance in the market is usually with PET strip at present
Base is base material, and it is main body that surface, which is coated with parting agent layer, and coating thereafter is shielded, and is torn it during use.
It is extensive with the market application but in the market applies the 95% of material using organosilicon coating at present, it is organic
Silicon does not apply to still in certain fields, such as in the typically inapplicable material containing organosilicon of electronic circuit process industry etc.
Material, because the remaining organosilicon bonded can influence the normal of its electronic circuit what following process or application time connect when peeling off
Use.
So have to use a kind of separated type material of non-organic silicon class in electronics industry.
Chinese patent CN103917347 proposes the mode using ethylene-tetrafluoroethylene copolymer material extrusion drawing and forming
Form fluorine-containing release membrane material so that film has release performance in itself.This membrane material can make directly as separated type material
With without being coated with release layer on film surface, there is the characteristics such as remaining adhesion rate is high, peeling force is low, surface brightness is high.But its table
Face tension force is too low, and peeling force is too small, and its recoatability has very big problem.
Chinese patent CN103923334 propose using silicon dioxide gel, add acrylate monomer, fluorochemical monomer,
Silicon-containing monomer, progress is free-radical polymerized to obtain fluorine silicon mould release, then coordinates with Isocyanates curing agent, is coated on organic substrate
On, obtain fluorine silicon mould release membrance by heat cure.This release product has higher hydrophobic, relatively low peeling force, higher remnants
The advantages that adhesion rate.Its surface is bright smooth, while wherein contains organosilicon material, is unfavorable for making in electronics industry
With.
