Description
Original applying number 2011101942641, on July 12 2011 applying date, denomination of invention is: a kind of preparation method of cloudy-surface release paper.
Technical field
The present invention relates to a kind of manufacturing process of the mould release membrance for organic pressure sensitive adhesive, belong to separated type material preparing technical field.
Background technology
Mould release membrance is coated on the top layer of environmental-protecting material PET, PE, OPP film substrate by silicone mould release, allows it can show extremely light and stable off-type force for various different organic pressure-sensing glue.
Pressure sensitive adhesive of different organic pressure-sensing glue such as PUR, acryl glue and rubber system etc., required mould release membrance off-type force is different, for needing, the viscosity of isolated product glue is different, the corresponding adjustment of off-type force, makes it to reach extremely light and stable off-type force when peeling off.
Concavo-convex in order to what the glue face of pressure-sensing glue can be made to acquire a certain degree, there are certain mist degree (roughness) and low reflecting effect in glue face, and has a kind of comfortable sensation when naked eyes see glue face, and Misty-faced release film serves vital effect.
At present, the preparation method of Misty-faced release film is: polished coarse by abrasive segments by film substrate; The dust on cleaning film substrate surface; Again at film substrate surface coating one deck mould release after washing, dust removal process.The shortcoming of the method is: the weight of polishing is inconsistent, film surface concavo-convex uneven, causes the peeling force of mould release membrance unstable, there is release bad risk, and the mist degree in pressure-sensing glue glue face is uneven, causes the waste of product.
Summary of the invention
The object of the invention is to provide a kind of manufacturing process of the mould release membrance for organic pressure sensitive adhesive.
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 sensitive adhesive, forms primarily of the following step:
