Abstract
The invention discloses a release film with small release force. The release film comprises a polyethylene film and a release agent layer, wherein a matte release agent is located between the polyethylene film and the release agent layer and comprises components in percentage by mass as follows: 5%-6% of silica particles, 25%-28% of acrylic polyols with the average molecular weight of 500-2,000, 42%-45% of resin of polyoxyalkylene series polyols with the average molecular weight of 500-2,500, 15%-17% of polyethylene glycol and 10% of the photoinitiator 184 which is 1-hydroxycyclohexyl phenyl ketone, wherein the particle size of the silica particles has peak values in the particle size ranges of 0.1-2 mu m and 1.5-5 mu m in the particle size distribution determined with a laser diffraction/scattering method, and the average particle size is 4 mu m or smaller than 4 mu m. By means of the matte release agent, the binding force of a lamination layer of release paper and the release agent is improved, the release force is stable, the anti-static performance of the film surface is improved, and the scratch resistance is improved simultaneously.
Description
Technical field
The present invention relates to a kind of release film, particularly a kind of release film of light off-type force.
Background technology
Separate-type paper, also known as interleaving paper, separate paper, is mainly used in being covered in the adhesive layer of surface for the protection of tape surface of adhesive tape.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 release film of light off-type force, and the release film of this light off-type force had both improve the leaching membrane layer of separate-type paper and the bonding force of parting agent and peeling force is stablized, and turn improves film surface anti-static performance, and also improves scratch resistance performance simultaneously.
For achieving the above object, the technical solution used in the present invention is: a kind of release film of light off-type force, the release film of described light off-type force comprises polyethylene film and parting agent layer, one mist-surface release agent is between polyethylene film and parting agent layer, and described mist-surface release agent is made up of the component of following masses percentage composition:
Silica granule 5 ~ 6%,
Molecular-weight average is the acrylic polyol 25 ~ 28% of 500 ~ 2000,
Molecular-weight average is resin 42 ~ 45 % of the polyoxyalkylene series polyvalent alcohol of 200 ~ 2500,
Polyoxyethylene glycol 15 ~ 17%,
1-hydroxycyclohexyl phenyl ketone-light trigger 184 10%;
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 4 μm or following in the scope of 0.1 ~ 2 μm and 1.5 ~ 5 μm.
In technique scheme, further improved plan is as follows:
In such scheme, described parting agent layer is silicone oil.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
1, separated type material mist-surface release agent of the present invention, its adopt 25 ~ 28% molecular-weight average be 500 ~ 2000 acrylic polyol and 42 ~ 45 % 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, the present invention is 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 ~ 10 μm, there is anti-static effect, then obtain cloudy surface release layer in surface-coated one deck parting agent coating of described cloudy surface coating.
