Abstract
The invention discloses an anti-static matte release agent. The matte release agent is located between a polyethylene glycol terephthalate film and a release agent layer and comprises components in percentage by mass as follows: 5%-6% of silica particles, 28%-30% of acrylic polyol with the average molecular weight of 500-2,000, 35% of polyoxyalkylene series polyol containing resin with the average molecular weight of 200-2,500, 18%-20% of polyethylene glycol and 10% of 1-hydroxycyclohexyl phenyl ketone, namely a photoinitiator 184, wherein the particle size of each silica particle 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 measured with a laser diffraction and scattering method, the average particle size is 4 mu m or smaller than 4 mu m, and the release agent is silicone oil. According to 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 meanwhile, the scratch resistance is improved.
Description
Technical field
The present invention relates to a kind of mould release, particularly the antistatic mist-surface release agent of one.
Background technology
Release liners, also known as barrier 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 release liners is generally the surperficial film one deck leaching membrane layer (material of employing mainly contains polyethylene) at release liners ground paper layer, is then coated with one deck mould release coating (material of employing is mainly silicone oil) on the surface of leaching membrane layer and obtains release liners.But because leaching membrane layer flatness is high, poor adhesive force between mould release coating and leaching membrane layer, when release liners attaches with the pad pasting being coated with trowel adhesive, the mould release coating in release liners is easily caused to be taken away by the adhesive that adhesion is larger, thus form in the local surfaces of pad pasting the mould release coating area being difficult to clean out, destroy pure, the uniformity of pad pasting entirety.And due to production process electrostatic excessive, causes the local out-of-flatness of release coating layer, not only affect product peeling force stability, and easily generation electrostatic spark causes fire.
Summary of the invention
The object of the invention is to provide a kind of antistatic mist-surface release agent, and this antistatic mist-surface release agent had both improve the leaching membrane layer of release liners and the adhesion of mould release 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 antistatic mist-surface release agent, described mist-surface release agent is between pet 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%,
Mean molecule quantity is acrylic polyol 28 ~ 30 % of 500 ~ 2000,
Mean molecule quantity is the resin 35% of the polyoxyalkylene series polyalcohol of 200 ~ 2500,
Polyethylene glycol 18 ~ 20%,
1-hydroxycyclohexyl phenyl ketone-light trigger 184 10%;
The particle diameter of described silica granule is that in the size distribution measured by laser diffraction and scattering method, particle diameter has peak value respectively and average grain diameter 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, the antistatic mist-surface release agent of the present invention, its adopt 28 ~ 30 % mean molecule quantities be 500 ~ 2000 acrylic polyol and 35% mean molecule quantity be the polyurethane resin of resin polymerization of the polyoxyalkylene series polyalcohol of 200 ~ 2500, mean molecule quantity be 500 ~ 2000 acrylic polyol and mean molecule quantity be that chain in the resin of the polyoxyalkylene series polyalcohol of 200 ~ 2500 improves film surface anti-static performance, and also improve scratch resistance performance simultaneously; Its polyalcohol acrylate monomer has the mean molecule quantity of 500 ~ 2000, if molecular weight is less than 500, the ABRASION RESISTANCE of film is tending towards reducing, if mean molecule quantity is more than 2000, during film-forming, applicability is deteriorated.If polyalcohol acrylate monomer is in particular ethylene glycol, consider water absorbing capacity, the present invention select mean molecule quantity be 200 ~ 1000 polyethylene 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 coating cloudy surface anti-static coating of thin 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 surperficial silicon-coating mould release coating coating, the bottom surface of silicon mould release coating coating infiltrates the notch place on described cloudy surface anti-static coating surface in the liquid state, silicon mould release coating coating is fixedly linked by notch place and cloudy surface anti-static coating after solidification, therefore, adhesion more firmly, reliably.And due to antistatic 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 electrostatic spark.
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 polymerisation 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 ABRASION RESISTANCE reduces; If if power is higher than 1200mW/cm
2, affect film flatness, applicability declines.Employing ultra-violet bands is 320 ~ 400nm, and illumination is 1200mW/cm
2described cloudy surface coating agent is irradiated, make described component carry out polymerisation 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 apply one deck mould release coating on the surface of described cloudy surface coating and obtain cloudy surface release layer.
