Abstract
Misty-faced release paper comprises a first lamination layer, a release paper original paper layer, a second lamination layer, a misty face coating and a release agent coating in sequential stack. Surface roughness of the misty face coating facing the release agent coating ranges from 2.821 micrometers to 3.324 micrometers. Two faces of the release paper original paper layer are coated with the lamination layers made of PE (polyethylene) by means of laminating, one of the lamination layers is coated with a polyester misty face coating, the surface of the polyester misty face coating is provided with a plurality of uniform concave-convex structures and coated with a silicon release agent coating, the bottom face of the silicon release agent coating in a liquid state seeps into recesses on the surface of the polyester misty face coating, and the silicon release agent coating is fixedly connected with the polyester misty face coating through the recesses after solidification, so that the misty-faced release paper is firmer and reliable in bonding. Furthermore, stripping force between the silicon release agent coating and the release paper original paper layer can be adjusted by adjusting misty level of the misty face 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 five layers by first leaching membrane layer, release liners original paper layer, second leaching membrane 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 it is the leaching membrane layer of PE that the utility model at first respectively drenches film one deck material to the two sides of release liners original paper layer (common paper); Coated polyester cloudy surface coating (material is a polyester) on therein the leaching membrane layer again; 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, first leaching membrane layer; 2, release liners original paper layer; 3, second leaching membrane layer; 4, cloudy surface coating; 5, mould release coating.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment: a kind of cloudy surface release liners
Shown in accompanying drawing 1; A kind of cloudy surface release liners; Stacked gradually for 5 five layers by first leaching membrane layer 1, release liners original paper layer 2, second leaching membrane layer 3, cloudy surface coating 4 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.Testing standard: ISO4287:1998.Roughness tester: the TR200 hand-held roughmeter of Beijing epoch peak Science and Technology Ltd. production.Said cloudy surface coating is a polyester cloudy surface coating.At first membrane material being drenched on the two sides of release liners original paper layer 2 (common paper) is first leaching membrane layer 1 and second leaching membrane layer 3 of PE; Coated polyester cloudy surface coating 4 (material is a polyester) on second leaching membrane layer 3 again; The surface has some even concaveconvex structures after treatment; In this surface coated silicon mould release coating 5, the notch place on said polyester cloudy surface coating 4 surfaces is infiltrated in the bottom surface of silicon mould release coating 5 under liquid state then, and silicon mould release coating 5 is fixedly linked through notch and polyester cloudy surface coating 4 after solidifying; Therefore, adhesion more firmly, reliably.But also can freely adjust the size of peeling force between silicon mould release coating 5 and the release liners body paper through regulating the mist degree (being roughness) of cloudy surface coating 4.
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 five layers by first leaching membrane layer, release liners original paper layer, second leaching membrane 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.
