Abstract
Frosted-surface release paper comprises a film coating layer, a raw release paper layer, an adhesive layer, a thin film layer, a frosted-surface coating, and a release agent coating which are overlapped sequentially, wherein the surface roughness of the surface of the frosted-surface coating, which faces the release agent coating, is 2.821 Mum to 3.324 Mum. As the surface of the thin film layer is coated with the polyester frosted-surface coating, the surface of the polyester frosted-surface coating is provided with a plurality of uniform concave-convex structures through processing, the silicone release agent coating is coated on the surface, the bottom surface of the silicone release agent coating permeates to the concave parts of the surface of the polyester frosted-surface coating, and the silicone release agent coating is fixedly connected with the polyester frosted-surface coating through the concave parts after solidification, the utility model has the advantage that the binding is firmer and more reliable. Moreover, the release force between the silicone release agent coating and the raw release paper layer can be adjusted freely by adjusting the frosted degree of the frosted-surface coating.
Description
Technical field
The utility model relates to a kind of cloudy surface release liners, the cloudy surface release liners that particularly a kind of adhesion strength is high, peeling force is adjustable.
Background technology
Release liners is claimed barrier paper, separate paper again, is mainly used in to paste the adhesive layer that is used for the protective tapes surface on the surface of adhesive tape.Existing release liners generally is to drench film one deck leaching membrane layer (material of employing mainly contains polyethylene) on the surface of release liners ground paper layer, and the surface coated one deck parting agent layer (material of employing is mainly silicone oil) at leaching membrane layer obtains release liners then.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 the mould release coating on the release liners to be taken away easily, thereby form the mould release coating area that is difficult to clean out, destroyed whole pure, the uniformity of pad pasting in the local surfaces of pad pasting by the bigger adhesive of adhesion.
Summary of the invention
The utility model provides a kind of cloudy surface release liners, and purpose is leaching membrane layer and the not high problem of mould release coating adhesion that solves release liners.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of cloudy surface release liners; Stacked gradually for six layers by leaching membrane layer, release liners original paper layer, adhesive layer, thin layer, cloudy surface coating and mould release coating and to constitute, the surface roughness of said cloudy surface coating towards the surface of said mould release coating is 2.821um～3.324um.
Related content in the technique scheme is explained as follows:
1, in the such scheme, said cloudy surface coating is a polyester cloudy surface coating.
2, in the such scheme, said mould release coating is to be used for isolating adhesive on the adhesive tape to make it and the release liners bonding, thus require its not with adhesive generation cross-linking reaction, the material of its use is mainly silicone oil.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
Because the utility model is at first to the surface coated polyester cloudy surface coating (material is a polyester) of thin layer; The surface has some even concaveconvex structures after treatment; In this surface coated silicon mould release coating, the notch place of said polyester cloudy surface coating surface is infiltrated in the bottom surface of silicon mould release coating under liquid state then, and silicon mould release coating is fixedly linked through notch and polyester cloudy surface coating after solidifying; Therefore, adhesion more firmly, reliably.But also can freely adjust the size of peeling force between silicon mould release coating and the release liners body paper through regulating the mist degree (being roughness) of cloudy surface coating.
Description of drawings
Accompanying drawing 1 is the utility model sketch map.
In the above accompanying drawing: 1, leaching membrane layer; 2, release liners original paper layer; 3, adhesive layer; 4, thin layer; 5, cloudy surface coating; 6, mould release coating.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment: cloudy surface release liners
Shown in accompanying drawing 1; A kind of cloudy surface release liners; Stacked gradually for 6 six layers by leaching membrane layer 1, release liners original paper layer 2, adhesive layer 3, thin layer 4, cloudy surface coating 5 and mould release coating and to constitute, the surface roughness of said cloudy surface coating 5 towards the surface of said mould release coating 6 is 2.821um～3.324um.Testing standard: ISO4287:1998.Roughness tester: the TR200 hand-held roughmeter of Beijing epoch peak Science and Technology Ltd. production.Said cloudy surface coating 5 is a polyester cloudy surface coating.At first the one side of release liners original paper layer 2 (common paper) being drenched membrane material is first leaching membrane layer 1 of PE; Another side coating one deck adhesive layer 3, applying thin film layer 4 on adhesive layer 3 again is then in the surface coated polyester cloudy surface coating 5 (material is a polyester) of thin layer 4; The surface has some even concaveconvex structures after treatment; In this surface coated silicon mould release coating 6, the notch place on said polyester cloudy surface coating 5 surfaces is infiltrated in the bottom surface of silicon mould release coating 6 under liquid state then, and silicon mould release coating 6 is fixedly linked through notch and polyester cloudy surface coating 5 after solidifying; Therefore, adhesion more firmly, reliably.But also can freely adjust the size of peeling force between silicon mould release coating 6 and the release liners body paper through regulating the mist degree (being roughness) of cloudy surface coating 5.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
Claims (2)
1. cloudy surface release liners; It is characterized in that: stacked gradually for six layers by leaching membrane layer, release liners original paper layer, adhesive layer, thin layer, cloudy surface coating and mould release coating and constitute, the surface roughness of said cloudy surface coating towards the surface of said mould release coating is 2.821um～3.324um.
2. cloudy surface release liners according to claim 1 is characterized in that: said cloudy surface coating is a polyester cloudy surface coating.
