Description
Technical field
The present invention relates to a kind of manufacturing process of the mould release membrance for organic pressure sensitivity glue, belong to the separated type material preparing technical field.
Background technology
Mould release membrance is that the silicone mould release is coated on the top layer of environmental-protecting material PET, PE, OPP film substrate, allows it can show extremely light and stable off-type force for various organic pressure-sensing glue.
Different organic pressure-sensing glue is the pressure sensitivity glue etc. of PUR, acryl glue and rubber system for example, required mould release membrance off-type force is different, at the viscosity difference of need isolated product glue, the corresponding adjustment of off-type force makes it the off-type force that reaches extremely light and stable when peeling off.
For the glue face that can make pressure-sensing glue acquire a certain degree concavo-convex, the glue face has certain mist degree (roughness) and low reflecting effect, and naked eyes have a kind of comfortable sensation when seeing the glue face, the cloudy surface mould release membrance has played crucial effects.
At present, the preparation method of cloudy surface mould release membrance is: film substrate is coarse by the abrasive segments polishing; Clean the dust on film substrate surface; Be coated with one deck mould release on the film substrate surface again after washing, the dust removal process.The shortcoming of this method is: the weight of polishing is inconsistent, and film surface concavo-convex inhomogeneous causes the peeling force instability of mould release membrance, have release bad risk, and the mist degree of pressure-sensing glue glue face is inhomogeneous, causes the waste of product.
Summary of the invention
The object of the invention provides a kind of manufacturing process of the mould release membrance for organic pressure sensitivity glue.
For achieving the above object, the technical solution used in the present invention is: a kind of manufacturing process of the mould release membrance for organic pressure sensitivity glue, mainly formed by the following step:

Related content in the technique scheme is explained as follows:
1, in the such scheme, the viscosity of described hydroxy silicon oil is 8000～10000cps.
2, in the such scheme, the viscosity of described polyurethane binder is 2000～2100cps.
3, in the such scheme, mould release claims interleaving agent, antitack agent, remover again.
4, in the such scheme, described hydroxy silicon oil, English name is: Hydroxy silicone oil is to telomerize the oligosiloxane that forms through ring body, and its structural formula is as follows:
The polysiloxane molecule main chain is the Si-O key, and bond energy is 462KJ/mol, and the bond energy of C-O is 369KJ/mol, and the bond energy of Si-O is bigger than C-O, so the good heat resistance of polysiloxanes.In addition, the bond distance of side chain Si-C is 0.193 nanometer, the bond distance of C-C is 0.154 nanometer, because the bond distance of Si-C is long, the steric hindrance that is connected in the methyl on the Si atom is little, so the methyl rotation is quite free, and when the C-C key connects methyl, the steric hindrance of methyl is big, so methyl can not rotate freely.In addition, the Si-O bond angle is bigger than C-O key, and silicon atom is bigger than carbon atom, methyl occupies suitable space when rotating around the Si-O key, and intermolecular gravitation is diminished, gravitation is little between polysiloxane molecule, illustrates that its cohesive energy is little, and resistance to bond and the cohesive energy of polymer are closely related.
6, in the such scheme, described Methyl Hydrogen Polysiloxane Fluid has another name called polymethyl hydrogen siloxane, containing hydrogen silicone oil, high containing hydrogen silicone oil, poly-methyl hydrogen radical siloxane, the high containing hydrogen silicone oil of methyl, 202 high containing hydrogen silicone oils, the poly-methyl of trimethylsiloxy group end-blocking.English name Polymethylhydrosiloxane, PMHS.CAS number: 63148-57-2; Molecular formula: C
3H
9OSi (CH
4OSi) nC
3H
9Si.Its structural formula is as follows:
。
7, in the such scheme, described hydroxy silicon oil and Methyl Hydrogen Polysiloxane Fluid are under the condition that the catalyst platinum exists, and mechanism's formula of the material that the reaction back generates is as follows:
。
8, in the such scheme, described polyurethane binder is polyurethane adhesive, refers to contain carbamate groups (NHCOO-) or NCO (adhesive NCO) in strand.Polyurethane adhesive is divided into polyisocyanates and polyurethane two big classes.Contain in the polyisocyanates strand isocyano group (NCO) and carbamate groups (NHCOO-), thus polyurethane adhesive show the height activity and polarity.With the base material that contains active hydrogen, as porous materials such as foam, plastics, timber, leather, fabric, paper, potteries, and the material of any surface finish such as metal, glass, rubber, plastics has the excellent in chemical bonding force.
9, in the such scheme, described aerosil (gas phase White Carbon black) is one of ultra tiny inorganic new material of extremely important high-tech, because its particle diameter is very little, so big, the surperficial absorption affinity of specific area is strong, and the surface can be big; Aspects such as chemical purity height, dispersive property are good, thermal resistance, resistance have special performance, with its superior stability, reinforcement, thickening property and thixotropy, show unique characteristics in numerous subjects and field.
10, in the such scheme, described talcous English is called PULVISTALCI, is the powder of white or off-white color, fine, no grittiness, and hand has been touched greasy feeling.CAS?No.：14807-96-6。
