Abstract
The invention discloses a method for making matte release paper for pressure sensitive tapes, which mainly comprises the following steps: 1, laminating a laminating layer on the surface of one side of release base paper, and then cooling the laminating layer; 2, coating a matte release agent on the laminating layer; and 3, drying the matte release agent. The matte release agent is prepared from the following raw materials: 27-35% of hydroxy silicone oil, 1-3% of curing agent, 5-8% of catalyst, 20-50% of polyurethane adhesive, 2-5% of fumed silica, and 15-47% of packing, wherein the curing agent is methyl hydrogen silicone oil; the catalyst is platinum; and the packing is talcum powder with particle diameter of less than or equal to 15 microns. The method disclosed by the invention is simple in production process and convenient to operate; the cost is reduced; and the release agent mixed with a fogging agent fills and levels up concave and convex parts of the surface of laminating paper, and matte release paper which is stable in stripping force and enables the surface of a pressure sensitive tape to have a good matte effect can be produced, so that the tape surface achieves a low light reflection effect.
Description
Technical field
The present invention relates to a kind of pressure-sensitive adhesive belt with the preparation method of cloudy-surface release paper, belong to the separated type material preparing technical field.
Background technology
Release liners claims barrier paper, and separate paper is a kind of prepreg adhesion that prevents, can protect again the not contaminated separate paper of prepreg.
Release liners is by spooning the certain thickness PE film of one deck on the body paper surface, then the silicone mould release is coated on environmental-protecting material PE film top layer, allows it can show extremely light and stable off-type force for various organic pressure sensitivity glue.
Different organic pressure-sensing glue are for example: pressure-sensing glue of hot melt adhesive, acryl glue and rubber system etc., required mould release membrance off-type force is different, viscosity for need isolated product glue is different, and the corresponding adjustment of off-type force makes it the off-type force that reaches extremely light and stable when peeling off.
Usually the way of cloudy-surface release paper is to drench the body paper surface to such an extent that the PE film polish coarsely by abrasive segments, and the dust on cleaning film surface is coated with one deck mould release again on the PE film after dust removal process.Its shortcoming: the weight of polishing is inconsistent, causes the peeling force of mould release membrance unstable, has 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 is to provide the preparation method that a kind of pressure-sensitive adhesive belt is used cloudy-surface release paper.
For achieving the above object, the technical solution used in the present invention is: a kind of pressure-sensitive adhesive belt preparation method of cloudy-surface release paper mainly is comprised of the following step:
