Abstract
The utility model discloses antistatic release paper. The release paper comprises a body paper layer, wherein a PE (polyethylene) film and a PET (polyethylene terephthalate) film are respectively coated on the upper surface and the lower surface of the body paper layer; an antistatic coating is coated on the other surface of the PET film of the body paper layer; a release agent coating is coated on the other surface of the antistatic coating; the surface, contacted with the release agent coating, of the antistatic coating is provided with a plurality of grooves; the depth of the grooves is 0.5-1mu m; the depth-to-width ratio of the grooves is 2:1; and the thickness ratio of the antistatic coating to the release agent coating is 1:2. The release paper has the advantages that the problem that the binding force of the film coated layer and the release agent coating of the existing release paper is not high is solved; and the probability of adsorbing dust and impurities can be greatly reduced, thus effectively avoiding severe losses caused by static electricity.
Description
Technical field
The utility model relates to a kind of release liners, relates in particular to a kind of 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, then at the table of leaching membrane layer and be coated with one deck parting agent layer (material of employing is mainly silicone oil) and obtain release liners.But high by ten leaching membrane layer flatness, 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; Next, and general release coating surface impedance is generally greater than 10
14Ω/sq produces static easily, easily adsorbs impurity, and hazard ratio is larger, has further destroyed the pure of pad pasting integral body.
Summary of the invention
The utility model provides a kind of antistatic release liners, and this antistatic release liners has solved the not high problem of the leaching membrane layer of existing release liners and mould release coating binding force; And can greatly reduce the probability of absorption dust and impurity, thereby the heavy losses of effectively having avoided static to cause.
For achieving the above object, the technical solution adopted in the utility model is: a kind of antistatic release liners, comprise upper surface and lower surface respectively film the original paper layer of PE film and PET film is arranged, another surface of PET film of original paper layer is coated with antistatic coating, and another surface of antistatic coating is coated with the mould release coating; The surface that described antistatic coating contacts with the mould release coating has several grooves, and this depth of groove is 0.5～1um.
Further improved technical scheme is as follows in the technique scheme:
1, in the such scheme, described groove depth-to-width ratio is 2:1.
2, in the such scheme, the Thickness Ratio of described antistatic coating and mould release coating is 1:2.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model antistatic release liners, the surface that its antistatic coating contacts with the mould release coating has some even concaveconvex structures, this depth of groove is 0.5～1um, then in this antistatic coating surface-coated silicon mould release coating, the notch place on described antistatic coating surface is infiltrated in the bottom surface of silicon mould release coating under liquid state, silicon mould release coating is fixedly linked by notch and antistatic coating after solidifying, therefore, adhesion is more firm, reliably, but also can by the dark wide and density of the groove of regulating antistatic coating, freely adjust the size of peeling force between silicon mould release coating and the release liners body paper; Secondly, another surface of PET film of original paper layer is coated with antistatic coating, and resistance value reaches 10
9～10
10Ω/sp greatly reduces the probability that adsorbs dust and impurity, thus the heavy losses of effectively having avoided static to cause.
Description of drawings
Accompanying drawing 1 is the utility model antistatic release liners structural representation.
In the above accompanying drawing: 1, PE film; 2, PET film; 3, original paper layer; 4, antistatic coating; 5, mould release coating; 6, groove.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: a kind of antistatic release liners, comprise upper surface and lower surface respectively film the original paper layer 3 of PE film 1 and PET film 2 is arranged, PET film 2 another surfaces of original paper layer 3 are coated with antistatic coating 4, antistatic coating 4 another surfaces are coated with mould release coating 5; The surface that described antistatic coating 4 contacts with mould release coating 5 has several grooves 6, and these groove 6 degree of depth are 0.5～1um.
Above-mentioned groove 6 depth-to-width ratios are 2:1.
Above-mentioned antistatic coating 4 is 1:2 with the Thickness Ratio of mould release coating 5.
When adopting above-mentioned antistatic release liners, the surface that its antistatic coating contacts with the mould release coating has some even concaveconvex structures, this depth of groove is 0.5～1um, then in this antistatic coating surface-coated silicon mould release coating, the notch place on described antistatic coating surface is infiltrated in the bottom surface of silicon mould release coating under liquid state, silicon mould release coating is fixedly linked by notch and antistatic coating after solidifying, therefore, adhesion is more firm, reliably, but also can by the dark wide and density of the groove of regulating antistatic coating, freely adjust the size of peeling force between silicon mould release coating and the release liners body paper; Secondly, another surface of PET film of original paper layer is coated with antistatic coating, and resistance value reaches 10
9～10
10Ω/sp greatly reduces the probability that adsorbs dust and impurity, thus the heavy losses of effectively having avoided static to cause.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
