A raw material formula of the fog face release agent comprises 25-35% of hydroxyl silicone oil, 0.5-4% of a curing agent, 2-8% of a catalyst, 34-42% of a polyurethane adhesive, 0.3-5% of fumed silica and 10-50% of filler, wherein the curing agent is methyl hydrogen silicone fluid; the catalyst is platinum; and the filler is talcum powder of which the practical diameter is less than or equal to 15 microns. The method disclosed by the invention is simple in production process and convenient to operate; and the cost is reduced. The concave-convex surface of laminated paper is filled and leveled up by the release agent mixed with a fog agent. The fog face release paper which has stable stripping strength and ensures that the adhesive surface of a pressure sensing adhesive has good haze effect can be produced, so that the adhesive surface has low-reflection effect.
Description
Technical field
The present invention relates to a kind of 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
