Abstract
The invention discloses an antistatic release material for protecting adhesive tapes, which is characterized in that the antistatic release material is positioned between a release film and a release agent layer. The antistatic release material is composed of the following components in percentage by mass: 6% of silica particle, 28% of polylol acrylate with the average molecular weight of 500-2000, 42% of polyoxyalkylene series polylol regsin with the average molecular weight of 200-2500, 17% of polyethyleneglycol and 7% of 1-hydroxycyclohexylphenylketone-photoinitiator. The fog release agent enhances the binding force between the coating layer and the release agent of the release layer, has stable stripping force, enhances the antistatic property of the film surface, and has especially excellent capacity for absorbing hydration water.
Description
Technical field
The present invention relates to a kind of separated type material, particularly a kind of protective tapes anti-static release material.
Background technology
Existing separate-type paper is generally the surperficial film one deck leaching membrane layer (material of employing mainly contains polyethylene) at separate-type paper ground paper layer, then obtains separate-type paper in surface coated one deck parting agent coating (material of employing is mainly silicone oil) of leaching membrane layer.But because leaching membrane layer planeness is high, poor adhesive force between parting agent coating and leaching membrane layer, when separate-type paper attaches with the pad pasting being coated with trowel adhesive, the parting agent coating in separate-type paper is easily caused to be taken away by the tackiness agent that adhesive power is larger, thus form in the local surfaces of pad pasting the parting agent coating area being difficult to clean out, destroy pure, the consistence of pad pasting entirety.And due to production process electrostatic excessive, causes the local unfairness of release coating layer, not only affect product peeling force stability, and easily generation static sparking causes fire.
Summary of the invention
The object of the invention is to provide a kind of protective tapes anti-static release material; this protective tapes anti-static release material had both improve the leaching membrane layer of separate-type paper and the bonding force of parting agent and peeling force is stablized; turn improve film surface anti-static performance, and also improve scratch resistance performance simultaneously.
For achieving the above object, the technical solution used in the present invention is: a kind of protective tapes anti-static release material, and described anti-static release material is positioned between release film and parting agent layer, and described anti-static release material is made up of the component of following masses percentage composition:
Silica granule 6%,
Molecular-weight average is the acrylic polyol 28% of 500 ~ 2000,
Molecular-weight average is the resin 42% of the polyoxyalkylene series polyvalent alcohol of 200 ~ 2500,
Polyoxyethylene glycol 17%,
1-hydroxycyclohexyl phenyl ketone-light trigger 1847%;
The particle diameter of described silica granule is that in the size-grade distribution measured by laser diffraction and scattering method, particle diameter has peak value respectively and median size is 4um or following in the scope of 0.1 ~ 2um and 1.5 ~ 5um.
In technique scheme, further improved plan is as follows:
1, in such scheme, described parting agent layer is silicone oil.
2, in such scheme, described release film is polypropylene film, polyethylene film or polyvinyl chloride film.
3, in such scheme, described release film thickness is 1.85 μm ~ 1.9 μm.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
1, protective tapes anti-static release material of the present invention, its adopt 20 ~ 30% molecular-weight average be 500 ~ 2000 acrylic polyol and 30 ~ 40% molecular-weight average be the urethane resin of resin polymerization of the polyoxyalkylene series polyvalent alcohol of 200 ~ 2500, molecular-weight average be 500 ~ 2000 acrylic polyol and molecular-weight average be that chain in the resin of the polyoxyalkylene series polyvalent alcohol of 200 ~ 2500 improves film surface anti-static performance, and also improve scratch resistance performance simultaneously; Its polyalcohol acrylate monomer has the molecular-weight average of 500 ~ 2000, if molecular weight is less than 500, the wear resistance of film is tending towards reducing, if molecular-weight average is more than 2000, during film-forming, suitability is deteriorated.If polyalcohol acrylate monomer is in particular ethylene glycol, consider water-retaining capacity, the present invention select molecular-weight average be 200 ~ 1000 polyoxyethylene glycol, make use of the ability of its superior absorption Bound moisture, further increase anti-static effect.Have the ability of the water of absorption Bound moisture form superior especially due to this acrylic polyol monomer, have anti-static effect, polyalcohol acrylate monomer all can use this monomer.
2, protective tapes anti-static release material of the present invention; first to the surface coated cloudy surface anti-static coating of thin film layer; by the surface after composition and engineering process, there is some even concaveconvex structures and anti-static effect through cloudy surface anti-static coating; then in this surface coated silicon parting agent coating coating; the bottom surface of silicon parting agent coating coating infiltrates the notch place on described cloudy surface anti-static coating surface in the liquid state; silicon parting agent coating coating is fixedly linked by notch place and cloudy surface anti-static coating after solidification; therefore, bonding force more firmly, reliably.And due to anti-electrostatic process, can eliminate electrostatic to the unstable impact brought of silicone oil coating, release peeling force can be very stable, also avoids the generation of production process static sparking.
3, adopt light trigger 1-hydroxycyclohexyl phenyl ketone to cause in the present invention, mainly consider that it is under wave band is 320-400nm UV-irradiation, can instantaneous solidification film forming, can deep cure be reached, there is good planarization and intensity.Described light trigger is 1-hydroxycyclohexyl phenyl ketone-light trigger 184, is a kind of ultraviolet initiator of efficient non yellowing, and for causing the UV polyreaction of unsaturated prepolymerization system, its mass content is 5 ~ 10%.
4, the power of medium ultraviolet light of the present invention adopts 1200mW/cm
2if mainly power is lower than 1200mW/cm
2, film not exclusively solidifies, and wear resistance reduces; If if power is higher than 1200mW/cm
2, affect film planeness, suitability declines.Employing ultra-violet bands is 320 ~ 400nm, and illumination is 1200mW/cm
2described cloudy surface coating-forming agent is irradiated, make described component carry out polyreaction under the effect of the specific 1-hydroxycyclohexyl phenyl ketone as light trigger of the present invention and obtain cloudy surface coating, thickness is 4 ~ 10um, there is anti-static effect, then obtain cloudy surface release layer in surface-coated one deck parting agent coating of described cloudy surface coating.
