Abstract
The invention discloses release paper used for a pressure sensitive tape. The release paper is formed by a base material and a microporous silicone adhesive release agent layer coating the base material, wherein the microporous silicone adhesive release agent layer is prepared by the following substances in percentage by mass through reaction: 50% of silicone adhesive, 3% of alpha,omega-dihydroxy polysiloxane, 3% of stannous octoate, 2% of isopropyl tri(dodecyl benzene sulfonyl ) titanate, 2% of inhibitor, 20% of MQ resin and 20% of chemical foaming agent; the inhibitor comprises at least one of Malay alcohol and alkynol; the chemical foaming agent comprises at least one of an azo-compound foaming agent, an N-nitroso compound foaming agent and a hydrazide compound foaming agent. According to the release paper, a common silicone adhesive release agent is made to be with different microcellular structures, and surface roughness is controlled by sizes and distribution arrangement of the microcellular structures.
Description
Original applying number 2012102347690, on July 9 2012 applying date, denomination of invention is: a kind of cloudy surface separated type material.
Technical field
The present invention relates to a kind of separate-type paper for Pressuresensitive Tape, belong to cloudy surface separated type material technical field.
Background technology
Separate-type paper claims again interleaving paper, and separate paper mainly plays the sticking object in isolation strip, such as Pressuresensitive Tape, is that one both can prevent prepreg adhesion, can protect again the not contaminated separate paper of prepreg, generally need to be stripped from use, abandon.The making method of existing separated type material is that parting agent (such as silicone oil) is coated on film (PET, PP, PE etc.) base material, or other base materials such as leaching membrane paper, Ge Laxin, control off-type force with different formulas, to meet the demand of different pressure-sensing glue (vinylformic acid, rubber, silica gel etc.).
Concavo-convex for what can make glue face acquire a certain degree, and there is the effect of low reflection and sub-light, the separated type material of cloudy surface has played vital effect.
At present, a kind of way of cloudy surface separated type material is to do coarse processing on film substrate surface through grinder buffing, after water washing dedust, be coated with one deck parting agent, finally form separated type material, the shortcoming of the method is that the weight of polishing differs, film surface concavo-convex inhomogeneous, finally coating separated type material off-type force is out unstable, have release bad risk, and pressure-sensing glue face is inhomogeneous, causes product waste.Another way is in parting agent, to add the filler of variable grain size, carry out the roughness of control surface by the number of filler, its shortcoming is that in coating process, sedimentation easily appears in filler, finally there is crawling in product, surface irregularity effect differs, due to the impact of filler, mist agent material and base material bonding force are not strong, easily produce shedding phenomenon.
Summary of the invention
The invention provides a kind of cloudy surface separated type material.
For achieving the above object, the technical solution used in the present invention is: a kind of separate-type paper for Pressuresensitive Tape, and described separate-type paper is made up of base material and the microporous type organic silica gel parting agent layer being coated on base material; The material of described microporous type organic silica gel parting agent layer is made after reaction by the material of following quality percentage composition:

Inhibitor 2%,
MQ resin 20%,
Chemical foaming agent 20%;
Described inhibitor is at least one in Malaysia alcohol and alkynol.
In technique scheme, further improved technical scheme is as follows:
1,, in such scheme, described chemical foaming agent is at least one in azo-compound whipping agent, N-nitroso compound whipping agent and hydrazide kind compound whipping agent.
2,, in such scheme, described azo-compound whipping agent is selected from Cellmic C 121, Diisopropyl azodicarboxylate, diisopropyl azodiformate, diethyl azodiformate, two azoaminobenzenes or Barium azodicarboxylate; Described N-nitroso compound whipping agent is selected from N, N '-dinitrosopentamethlyene tetramine or N, N '-dimethyl-N, N '-dinitrosoterephthalamine; Described hydrazide kind compound whipping agent is selected from 4,4 '-disulfonyl hydrazide diphenyl ether, to benzol sulfohydrazide, 3,3 '-disulfonyl hydrazide sulfobenzide, 4,4 '-bis-benzene disulfohydrazides, 1,3-benzene disulfohydrazide or Isosorbide-5-Nitrae-benzene disulfohydrazide.
3, in such scheme, described alkynol is selected from propiolic alcohol, methylbutynol, methylparafynol, l-hexyn-3-ol, 3,6-dimethyl-4-octyne-3,6-glycol, 2,5-dimethyl-3-hexin-2,5-glycol, ethyl octyne alcohol or 2,4,7,9-tetramethyl--5-decine-4,7-glycol.
4,, in such scheme, the thickness of described microporous type organic silica gel parting agent layer is 1 micron ~ 1 centimetre.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
1, the present invention is transformed into general organic silicon adhesive the microporous type organic silicon adhesive with microvoid structure, makes organic silicon adhesive have venting quality, adsorptivity, and micropore is hollow simultaneously, has the micromolecular function of absorption.The microvoid structure size of organic silicon adhesive can regulate, micropore arranged evenly can be tightly can pine, can be according to final requirement, decide the structure of micropore and the size of viscosity.
2, the present invention is by general silica gel parting agent is made and had different microvoid structures, the size by microvoid structure and arranged evenly come the roughness of control surface.
