Abstract
The invention discloses a kind of PET mould release membrances with from release function, it is made up of following weight parts composition：Dicarboxylic acid monomer 1,200 2000, glycol monomer 500 1000, fluorosilicone pre-polymer 50 200, catalyst 0.5 2；And the preparation method of the mould release membrance.Obtained PET mould release membrances surface of the invention need not be coated with fluorine silicon mould release, just with release effect, enormously simplify the technique of pressure sensitive adhesive coating industry, reduce the harm of production cost and solvent to environment.
Description
Technical field
The present invention relates to polyester film and coating technology field, especially a kind of PET mould release membrances with from release function and
Its preparation method.
Background technology
Mould release membrance is without viscosity, or slight sticky membrane material after being contacted under limited conditions with specific material
Material.Why current PET mould release membrances have release effect, be primarily due to surface be coated with one layer of silicone oil with barriering effect or
Person's fluorine element silicone oil.
However, in produce reality, coating organosilicon mould release or fluorine element mould release need to use fluorine carbon molten on PET film
Agent, isopropanol equal solvent are diluted and it is necessary to which the high temperature more than 150 DEG C is solidified, and the PET mould release membrances prepared are also
Needs carry out prolonged curing can be used.Complex manufacturing, consumed energy are larger, and the production cycle is very long.Fluorine silicon coating
Produced adhesive force is relatively low and PET film surface between, desiliconization phenomenon, hamper fluorine element a series of problems, such as off-type force is larger
The development of mould release membrance.Therefore, how on the basis of PET film excellent properties are maintained, assign its own release effect and be undoubtedly
The basic method for solving the above problems.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes a kind of PET mould release membrances with from release function, without coating from
Type agent, just have release effect, solve adhesive force produced between traditional fluorine silicon coating and PET film surface relatively low, de-
Silicon phenomenon, a series of problems, such as off-type force is larger.
In order to realize foregoing invention purpose, the present invention provides following technical scheme：A kind of PET with from release function from
Type film, is made up of following weight parts composition：
Dicarboxylic acid monomer 1200-2000
Glycol monomer 500-1000
Fluorosilicone pre-polymer 1-200
Catalyst 0.5-2.
Further, the structural formula of the fluorosilicone pre-polymer is as follows：
Wherein, R is the construction unit containing hydroxyl, carboxyl or epoxide group；R ' is（n≥
4）, R1, R2, R3, R4In at least one contain（n≥5）Construction unit, remaining is,Construction unit.
Further, R is、、、、WithIn
One kind.
Further, the dicarboxylic acid monomer is terephthalic acids, isophthalic acid or phthalic acid.
Further, the dicarboxylic acid monomer is containing the terephthalic acids for fluoro, isophthalic acid or faces phthalic acid.
Further, the glycol monomer is to ethylene glycol or propane diols.
Further, the glycol monomer is fluoro-diol.
Further, the fluoro-diol is PFPE glycol or bisphenol AF.
Further, the catalyst is antimony glycol.
A kind of preparation method of PET mould release membrances as described above, including procedure below：Dicarboxylic acid monomer, two by weight
First alcohol monomer, fluorosilicone pre-polymer and catalyst, are added in reactor and heating stirring carries out esterification；Esterification terminates
Cooling granulation, forms masterbatch afterwards, is prepared after melting biaxial tension with the fluorine element mould release membrance from release function.
Compared with prior art, the present invention has advantages below：PET mould release membrances surface need not be coated with fluorine silicon mould release,
Just there is release effect, enormously simplify the technique of pressure sensitive adhesive coating industry, reduces the danger of production cost and solvent to environment
Evil.
