Abstract
The utility model discloses an antistatic releasing film. The antistatic releasing film comprises a polyester film; a PE (Poly Ethylene) film is coated on one surface of the polyester film, and an antistatic coating is coated on the other surface of the PE film on the polyurethane film; a release agent coating is coated on the other surface of the antistatic coating; a plurality of concave grooves 0.5 to 1 micron in depth are formed in the contact surface between the antistatic coating and the release agent coating; the concave grooves are in a depth-to-width ratio of 1: 2; and the ratio of thicknesses of the antistatic coating and the release agent coating is 1: 2. By adopting the antistatic releasing film, the problem of a conventional releasing film that a coating layer and the release agent coating are in poor combination is solved, the probability of absorbing dust and impurities is greatly reduced, and therefore, the serious losses due to the static can be effectively avoided.
Description
Technical field
The utility model relates to a kind of release liners, relates in particular to a kind of anti-static release film.
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 anti-static release film, and this anti-static release film 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 anti-static release film, comprise a polyester film, and this polyester film one surperficial film has the PE film, another surface of PE film of this polyester film 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 1:2.
2, in the such scheme, described antistatic coating and mould release coating layer thickness ratio are 1:2.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model anti-static release film, 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 PE film of its polyester film 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 anti-static release film structural representation.
In the above accompanying drawing: 1, polyester film; 2, PE film; 3, antistatic coating; 4, mould release coating; 5, groove.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: a kind of anti-static release film, comprise a polyester film 1, these polyester film 1 one surperficial films have PE film 2, and PE film 2 another surfaces of this polyester film 1 are coated with antistatic coating 3, and antistatic coating 3 another surfaces are coated with mould release coating 4; The surface that described antistatic coating 3 contacts with mould release coating 4 has several grooves 5, and these groove 5 degree of depth are 0.5～1um.
Above-mentioned groove 5 depth-to-width ratios are 1:2.
Above-mentioned antistatic coating 3 is 1:2 with mould release coating 4 thickness proportion.
When adopting above-mentioned anti-static release film, 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 PE film of its polyester film 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.
