Abstract
A piece of coating type release paper is manufactured by coating spray film release agents on raw paper. Raw material formula of the spray film release agents contains 20-70% of polyvinyl alcohol water solution, 22-60% of emulsion type organic silicone release agents, 6-12% of stabilizing agents, 0.3-2% of emulsifying agents, 1.2-4.5% of catalysts and 0.5-3.5% of cross-linking agents. At least one of agar, gelatin and water-soluble starch is adopted as the stabilizing agents, at least one of sodium polyphosphate, polysorbate 80 and tributyl phosphate is adopted as the emulsifying agents, platinum catalysts or benzoyl peroxide are adopted as the catalysts, and methyl hydrogen-containing silicone oil is adopted as the cross-linking agents. The coating type release paper is simple in production process flow, low in cost and convenient to operate.
Description
Technical field
The present invention relates to a kind of application type release liners, particularly a kind of filmogen that utilizes is coated on the release liners that the body paper surface forms.
Background technology
Release liners is claimed barrier paper again, and separate paper is a kind of prepreg adhesion that prevents, can protect the not contaminated separate paper of prepreg again.The pressure sensitivity glue of different organic pressure-sensing glue such as PUR, acryl glue and rubber system etc.; Required release liners off-type force is different; Viscosity to need isolated product glue is different, and off-type force should be adjusted relatively, makes it the off-type force that when peeling off, reaches extremely light and stable.
Release liners is through spooning the certain thickness polyethylene leaching membrane layer of one deck on the body paper surface, the silicon mould release is coated on the polyethylene leaching membrane layer again, letting it can show certain off-type force for various organic pressure sensitivity glue.
At present, the manufacture craft of release liners need go on foot production technologies through two: the first step is drenched the polyethylene leaching membrane layer on the body paper surface earlier; Second step: silicon-coated mould release on the polyethylene leaching membrane layer again; The instability of the performance of the performance of polyethylene leaching membrane layer and silicon mould release coating all can influence the performance of release liners, and, silicon mould release crawling inhomogeneous such as the top layer of the bubble on the polyethylene leaching membrane layer, polyethylene leaching membrane layer be even etc. all can influence the performance of release liners.And, need the energy of labor during the prior art for preparing release liners, so be necessary to provide a kind of low energy consumption, quality controllable application type release liners.
Summary of the invention
The object of the invention provides a kind of application type release liners.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of application type release liners, and said application type release liners is coated on the body paper and makes by drenching the film mould release, and the composition of raw materials of said pouring film mould release is made up of the material of following quality percentage composition:
Polyvinyl alcohol water solution 20 ~ 70%;
Emulsion-type silicone release agent 22 ~ 60%;
Stabilizing agent 6 ~ 12%;
Emulsifying agent 0.3 ~ 2%;
Catalyst 1.2 ~ 4.5%;
Crosslinking agent 0.5 ~ 3.5%;
Said stabilizing agent is at least a in agar, gelatin and the water soluble starch; Said emulsifying agent is at least a in sodium polyphosphate, Tween 80 and the tributyl phosphate; Said catalyst is platinum catalyst or benzoyl peroxide; Said crosslinking agent is a Methyl Hydrogen Polysiloxane Fluid.
Related content in the technique scheme is explained as follows:
In the such scheme, the viscosity of said polyvinyl alcohol water solution is 700 ~ 5000cps.Polyvinyl alcohol (polyvinyl alcohol PVA) is a kind of monomer polymerization of can't help, but the water-soluble polymer that obtains through the polyvinyl acetate hydrolysis.The mass percentage concentration of polyvinyl alcohol water solution reaches at 12% ~ 23% o'clock, and viscosity can reach 800 ~ 5000cps.
2, in the such scheme, the viscosity of said emulsion-type silicone release agent is 80 ~ 500cps.The agent of emulsion-type silicone release can be described as the emulsion-type Organosilicon Release Agent again.
3, in the such scheme, said crosslinking agent is the Methyl Hydrogen Polysiloxane Fluid emulsion, and it is to be the emulsion oil-in-water that main body forms by Methyl Hydrogen Polysiloxane Fluid.
4, in the such scheme, the general formula of sodium polyphosphate is Na
(n+2)P
nO
(3n+1), it is a kind of of polymeric phosphate, comprises that sodium phosphate trimer, five polyphosphate sodiums, hexapolyphosphate sodium are so that higher polyphosphate sodium.
Because the technique scheme utilization, the present invention compared with prior art has advantage and effect:
1, PVA resin of the present invention can 80 ~ 100 ℃ water-soluble, have good film forming, can the good fastness that combines be arranged with the body paper surface.Because the PVA resin has the good fastness that combines with the release liners body paper, so it can be at body paper envelope formation rete, to stop the diffusion inside of moisture to body paper.
2, the present invention is owing to solvent for use in the composition of raw materials is a water, and cost is low; And, therefore can environment not polluted because of the volatilization of organic solvent in the application stage of mould release owing to do not contain organic solvent in the composition of raw materials.
3, the technological process of production of the present invention is simple, and cost is low, handled easily.
