Description

Anti scuffing cloudy surface antistatic release liners
Technical field
The present invention relates to a kind of cloudy surface antistatic release liners, particularly a kind of anti scuffing cloudy surface antistatic release liners.
Background technology
Release liners claims again barrier paper, separate paper, is mainly used in pasting on the surface of adhesive tape for the protection of the adhesive layer of tape surface.Existing release liners generally is the surperficial film one deck leaching membrane layer (material of employing mainly contains polyethylene) at the release liners ground paper layer, and then the surface-coated one deck mould release coating (material of employing is mainly silicone oil) at leaching membrane layer obtains release liners.But because the leaching membrane layer flatness is high, poor adhesive force between mould release coating and the leaching membrane layer, when release liners attaches with the pad pasting that is coated with trowel adhesive, cause easily the mould release coating on the release liners to be taken away by the larger adhesive of adhesion, thereby the local surfaces at pad pasting forms the mould release coating area that is difficult to clean out, and has destroyed pure, the uniformity of pad pasting integral body.And because production process static is excessive, cause the local out-of-flatness of release coating layer, not only affect product peeling force stability, and produce easily electrostatic spark and cause fire.
Summary of the invention
The object of the invention provides a kind of anti scuffing cloudy surface antistatic release liners, this anti scuffing cloudy surface antistatic release liners had both solved the leaching membrane layer of release liners and the mould release coating binding force is not high, peeling force is unstable, improve again film surface anti-static performance, and also improved the scratch resistance performance simultaneously.
For achieving the above object, the technical solution used in the present invention is: a kind of anti scuffing cloudy surface antistatic release liners, described anti scuffing cloudy surface antistatic release liners comprises that a surperficial film has the release liners body paper of leaching membrane layer, another surface-coated one adhesive layer of this release liners body paper, another surface of this adhesive layer is bonded with thin layer, another surface-coated a layer thickness of this thin layer is 0.2 ~ 2 micron cloudy surface anti-static coating, and another surface of cloudy surface anti-static coating is coated with silicon layer; The surface that described cloudy surface anti-static coating contacts with silicon layer has some sags and crests;
Described cloudy surface anti-static coating is comprised of the component of following quality percentage composition:
Silica granule 2 ~ 6%,
Mean molecule quantity is 500 ~ 2000 acrylic polyol 20 ~ 30 %,
Mean molecule quantity is resin 30 ~ 40 % of 200 ~ 2500 polyoxyalkylene series polyalcohol,
Polyethylene glycol 15 ~ 20%,
Cyclohexyl methyl siloxanes 4 ~ 8%,
1-hydroxy-cyclohexyl phenyl ketone-light trigger 184 5 ~ 10%;
The particle diameter of described silica granule has respectively peak value for particle diameter in the size distribution of being measured by the laser diffraction and scattering method in the scope of 0.1 ~ 2um and 1.5 ~ 5um and average grain diameter is 4um or following.
Further improved plan is as follows in the technique scheme:
1, in the such scheme, it is 280nm ~ 350nm that described cloudy surface anti-static coating adopts ultraviolet wave band, and illumination is 1200mW/cm 2, described cloudy surface anti-static coating is shone, make described component under the effect of 1-hydroxy-cyclohexyl phenyl ketone-light trigger 184, carry out polymerisation and obtain the cloudy surface anti-static coating.
2, in the such scheme, the material of described leaching membrane layer is polyethylene terephthalate, polypropylene, polyethylene or polyvinyl chloride.
3, in the such scheme, described thin layer is pet film layer, layer of polypropylene foil, film layer, polyvinyl chloride layer or cast polypropylene film layer.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
1, anti scuffing cloudy surface antistatic release liners of the present invention, it adopts 20 ~ 30 % mean molecule quantities is that 500 ~ 2000 pure and mild 30 ~ 40 % mean molecule quantities of acrylic acid multielement are to mix behind the polyurethane resin that forms of the resin polymerization of 200 ~ 2500 polyoxyalkylene series polyalcohol and with cyclohexyl methyl siloxanes 4 ~ 8%, mean molecule quantity is that 500 ~ 2000 acrylic polyol and mean molecule quantity are that chain in the resin of 200 ~ 2500 polyoxyalkylene series polyalcohol has improved film surface anti-static performance, and has also improved the scratch resistance performance simultaneously; Its polyalcohol acrylate monomer has 500 ~ 2000 mean molecule quantity, if molecular weight less than 500, the ABRASION RESISTANCE of film is tending towards reducing, if mean molecule quantity surpasses 2000, applicability variation during film-forming.If the polyalcohol acrylate monomer is in particular ethylene glycol, consider water absorbing capacity, it is 200 ~ 1000 polyethylene glycol that the present invention selects mean molecule quantity, has utilized its superior absorption in conjunction with the ability of water, has further improved anti-static effect.Because this polyalcohol acrylic monomers has superior especially absorption in conjunction with the ability of the water of water form, has anti-static effect, the polyalcohol acrylate monomer all can use this monomer.
2, the present invention is at first to the surface-coated cloudy surface anti-static coating of thin layer, surface after the cloudy surface anti-static coating is processed by composition and engineering has some even concaveconvex structures and anti-static effect, then in this surface-coated silicon mould release coating coating, the notch place on described cloudy surface anti-static coating surface is infiltrated in the bottom surface of silicon mould release coating coating under liquid state, silicon mould release coating coating is fixedly linked by notch place and cloudy surface anti-static coating after solidifying, therefore, adhesion more firmly, reliably.And because antistatic is processed, can eliminate static to the unstable impact that brings of silicone oil coating, release peeling force can be very stable, also avoids the generation of production process electrostatic spark.
3, adopting light trigger 1-hydroxy-cyclohexyl phenyl ketone to cause among the present invention, mainly is to consider that it is under the 320-400nm UV-irradiation at wave band, but the instantaneous solidification film forming can reach deep layer curing, has good planarization and intensity.Described light trigger is 1-hydroxy-cyclohexyl phenyl ketone-light trigger 184, is a kind of efficient not ultraviolet initiator of xanthochromia, is used for causing the UV polymerisation of unsaturated prepolymerization system, and its mass content is 5～10 %.
4, anti scuffing cloudy surface antistatic release liners of the present invention, described silica granule is that particle diameter is that particle diameter has respectively peak value and average grain diameter is 4um or following silica granule in the size distribution of being measured by the laser diffraction and scattering method in the scope of 0.1 ~ 2um and 1.5 ~ 5um, both greatly improve atomized surface effect, guaranteed again solidification effect.
5, the power of medium ultraviolet light of the present invention adopts 1200mW/cm 2If mainly be that power is lower than 1200mW/cm 2, film not exclusively solidifies, and ABRASION RESISTANCE reduces; If if power is higher than 1200mW/cm 2, affecting the film flatness, applicability descends.Adopting ultraviolet wave band is 320 ~ 400nm, and illumination is 1200mW/cm 2Described cloudy surface coating agent is shone, make described component under the effect of the specific 1-hydroxy-cyclohexyl phenyl ketone as light trigger of the present invention, carry out polymerisation and obtain the cloudy surface coating, thickness is 4 ~ 10um, have anti-static effect, apply one deck mould release coating on the surface of described cloudy surface coating again and obtain the cloudy surface release layer.
