Description

High reliability adhesive tape cloudy surface separated type material
Technical field
The present invention relates to a kind of cloudy surface separated type material, more particularly to a kind of high reliability adhesive tape cloudy surface separated type material.
Background technology
Existing release film is usually one layer of leaching membrane layer of surface lamination in release paper ground paper layer（The material of use mainly has Polyethylene）, then one layer of mould release coating is coated on the surface of leaching membrane layer（The material of use is mainly silicone oil）Obtain release paper. But due to leaching membrane layer flatness height, poor adhesive force between mould release coating and leaching membrane layer, when release paper is with being coated with high viscosity When the pad pasting of adhesive attaches, the adhesive that the mould release coating that is easy to cause in release paper is attached power bigger is taken away, so as to The mould release coating area cleaned up is difficult in the local surfaces formation of pad pasting, destroys pure, the consistency of pad pasting entirety.And And since production process electrostatic is excessive, lead to the out-of-flatness of release coating layer part, product peeling force stability is not only influenced, but also Easily generating electrostatic spark leads to fire.
Invention content
It is an object of the present invention to provide a kind of high reliability adhesive tape cloudy surface separated type material, the high reliability adhesive tape cloudy surface from Section bar material binding force is high, peeling force is stablized, and improves film surface antistatic performance and scratch resistance performance.
In order to achieve the above objectives, the technical solution adopted by the present invention is：A kind of high reliability adhesive tape cloudy surface separated type material, It is characterized in that：The cloudy surface separated type material is in the release paper of adhesive tape, the cloudy surface separated type material to be by following masses percentage The component composition of content：
Silica granule 5%,
Average molecular weight is 500 ~ 2000 acrylic polyol 27%,
Average molecular weight is the resin 39% of 200 ~ 2500 polyoxyalkylene series polyalcohol,
Polyethylene glycol 18%,
Cyclomethicone 6%,
1- hydroxycyclohexyl phenyl ketones-photoinitiator 1845%；
The grain size of the silica granule be in the size distribution measured by laser diffraction scattering method grain size 0.1 ~ 2 μm and 1.5 ~ It is 4 μm or less that peak value and average grain diameter are respectively provided in the range of 5 μm；
The cloudy surface anti-static coating uses ultra-violet bands as 280nm ~ 350nm, illumination 1200mW/cm2, to the cloudy surface Anti-static coating is irradiated, and the component is made to be gathered under the action of 1- hydroxycyclohexyl phenyl ketones-photoinitiator 184 Cloudy surface anti-static coating is obtained by the reaction in conjunction.
Further improved scheme is as follows in above-mentioned technical proposal：
1st, in said program, the ultra-violet bands are 315nm ~ 320nm.
2nd, in said program, the film layer is film layer or polyvinyl chloride layer, poly terephthalic acid second two One kind in alcohol ester film layer, layer of polypropylene foil.
3rd, in said program, a diameter of 2.5 ~ 2.8 microns of the silica granule.
Since above-mentioned technical proposal is used, the present invention has following advantages and effect compared with prior art：
1st, high reliability adhesive tape cloudy surface separated type material of the present invention, use 20 ~ 30% average molecular weight for 500 ~ 2000 propylene The poly- ammonia that sour polyalcohol and the resin polymerization of polyoxyalkylene series polyalcohol that 30 ~ 40% average molecular weight are 200 ~ 2500 form It is mixed after ester resin and with cyclomethicone 4 ~ 8%, average molecular weight is 500 ~ 2000 acrylic polyol and mean molecule The chain measured in the resin for 200 ~ 2500 polyoxyalkylene series polyalcohol improves film surface antistatic performance, and also carry simultaneously High scratch resistance performance；Its polyalcohol acrylate monomer has 500 ~ 2000 average molecular weight, if molecular weight is less than 500, The wearability of film tends to reduce, if average molecular weight is more than 2000, applicability is deteriorated during film-forming.If polyalcohol propylene Acid ester monomer is specifically for ethylene glycol, it is contemplated that water absorbing capacity, the present invention select average molecular weight for 200 ~ 1000 polyethylene glycol, Its superior ability absorbed with reference to water is utilized, further improves anti-static effect.Due to this acrylic polyol list Body has especially advantageous absorption with reference to the ability of the water of water form, has anti-static effect, polyalcohol acrylate monomer is complete Portion can use this monomer.
2nd, the present invention is coated with cloudy surface anti-static coating to the surface of film layer first, passes through formula through cloudy surface anti-static coating There is several uniform concaveconvex structures and anti-static effect with the surface after process, then applied in this surface silicon-coating mould release Layer coating, the bottom surface of silicon mould release coating coating penetrated into the liquid state at the notch on the cloudy surface anti-static coating surface, silicon from Type agent coating coating at notch with cloudy surface anti-static coating after solidification by being fixedly linked, therefore, binding force more securely, can It leans on.And due to antistatic process, electrostatic can be eliminated, the unstable influence brought is coated with to silicone oil, release peeling force can be very steady It is fixed, also avoid the generation of production process electrostatic spark.
3rd, caused in the present invention using photoinitiator 1- hydroxycyclohexyl phenyl ketones, mainly consider that it is in wave band Under 320-400nm ultraviolet lights, can instantaneous solidification film forming, can reach deep cure, have good planarization and intensity.Institute Photoinitiator is stated as 1- hydroxycyclohexyl phenyl ketones-photoinitiator 184, is a kind of ultraviolet initiator of efficient non yellowing, For causing the UV polymerisations of unsaturated prepolymerization system, mass content is 5~10%.
4th, high reliability adhesive tape cloudy surface separated type material of the present invention, the silica granule are grain size to be dissipated by laser diffraction It is 4 μ to penetrate grain size in the size distribution of method measure and peak value and average grain diameter are respectively provided in the range of 0.1 ~ 2 μm and 1.5 ~ 5 μm M or following silica granule, both substantially increase atomized surface effect, in turn ensure solidification effect.
5th, the power of ultraviolet light uses 1200mW/cm in the present invention2Mainly if power is less than 1200mW/cm2, film is endless All solidstate, wearability reduce；If if power is higher than 1200mW/cm2, film flatness is influenced, applicability declines.Using ultraviolet light wave Section is 320 ~ 400nm, illumination 1200mW/cm2, the cloudy surface coating agent is irradiated, makes the component of the invention special Be set for carrying out under the action of the 1- hydroxycyclohexyl phenyl ketones for photoinitiator polymerisation and obtain cloudy surface coating, thickness for 4 ~ 10 μm, there is anti-static effect, then coat one layer of mould release coating on the surface of the cloudy surface coating and obtain cloudy surface release layer.
