Abstract
Curl prevention four-layer type vague surface release paper comprises a release paper raw paper layer (1), a first coating layer (2) and a vague surface release agent coating (3), and is characterized by further comprising a second coating layer (4), wherein the second coating layer (4), a release paper raw paper layer (1), the first coating layer (2) and the vague surface release agent coating (3) are stacked in sequence. Due to the fact that two sides of raw paper of the release paper raw paper layer are both provided with the coating layers, the raw paper is protected. Therefore, the raw paper is not prone to curl after absorbing water and affected with damp, and the problem that the other side of the release paper raw paper layer in the structure of the exiting three-layer type vague surface release paper is lack of a protection layer so that the raw paper curls easily after absorbing water and affected with damp.
Description
Technical field
The utility model relates to the release liners technical field, and particularly a kind of four curling stratotype cloudy surfaces of rear generation that can prevent from making moist are release low.
Background technology
Release liners also claims barrier paper or separate paper, and it is a kind of prepreg adhesion that prevents, can protect again the not contaminated separate paper of prepreg.Different organic pressure-sensing glue, such as: pressure sensitivity glue of hot melt adhesive, acryl glue and rubber system etc., the off-type force of required release liners is different.Viscosity for organic pressure-sensing glue of need isolation is different, and off-type force should be adjusted accordingly, and makes it the effect that reaches extremely light and stable when peeling off.
Chinese patent CN202175888U discloses a name and has been called " Novel matte-surface release paper ", and the patent No. is the utility model patent of 201120244945.X.Its scheme is to be stacked gradually by three layers of release liners original paper layers, leaching membrane layer, mould release coating to consist of.Because the release liners original paper layer is positioned at top layer or bottom in three-decker, the body paper another side on the release liners original paper layer does not have protective layer, thus body paper easily suction make moist and occur curlingly, and curling phenomenon is more serious after through the baking box coating.For this reason, how addressing this problem is the problem of the utility model research.
Summary of the invention
The utility model provides a kind of four curling stratotype cloudy-surface release papers that prevent, and is intended to solve that the release liners original paper layer lacks protective layer in the existing three stratotype cloudy-surface release paper structures, easily the suction problem of making moist.
For achieving the above object, the technical solution adopted in the utility model is: a kind ofly prevent four curling stratotype cloudy-surface release papers, comprise release liners original paper layer, the first leaching membrane layer and mist-surface release agent coating, its innovation is: also comprise the second leaching membrane layer, described the second leaching membrane layer, release liners original paper layer, the first leaching membrane layer and mist-surface release agent coating stack gradually formation.
Related content in the technique scheme is explained as follows:
1. in the such scheme, described mist-surface release agent coating has first surface and second surface, and wherein, first surface contacts with the first leaching membrane layer, and the surface roughness of second surface is 0.3 micron～4.5 microns.
2. in the such scheme, described the first leaching membrane layer and the second leaching membrane layer are laminated polyester film.
The utility model operation principle and effect are: in four stratotype cloudy-surface release paper structures, described the second leaching membrane layer, release liners original paper layer, the first leaching membrane layer and mist-surface release agent coating are stacked gradually the formation cloudy-surface release paper.Because the body paper both sides on the release liners original paper layer are equipped with leaching membrane layer; this is two-layer not only to have self original function; and formed natural protective layer in the both sides of body paper; body paper has been played protective effect; therefore body paper be not easy suction make moist occur curling; solved that release liners original paper layer another side lacks protective layer in the existing three stratotype cloudy-surface release paper structures, easily suction is made moist curling problem is occured.
Description of drawings
Accompanying drawing 1 is the schematic cross-section of the utility model four-layer structure.
In the above accompanying drawing: 1. release liners original paper layer; 2. the first leaching membrane layer; 3. mist-surface release agent coating; 4. the second leaching membrane layer.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: a kind ofly prevent four curling stratotype cloudy-surface release papers
Shown in accompanying drawing 1, this four stratotypes cloudy-surface release paper, comprise release liners original paper layer 1, the first leaching membrane layer 2 and mist-surface release agent coating 3, its improvement is: also comprise the second leaching membrane layer 4, described the second leaching membrane layer 4, release liners original paper layer 1, the first leaching membrane layer 2 and mist-surface release agent coating 3 stack gradually formation.Described mist-surface release agent coating 3 has first surface and second surface, and wherein, first surface contacts with the first leaching membrane layer 2, and the surface roughness of second surface is 0.3 micron～4.5 microns.Roughness tester: the TR200 Manual roughness devices of Beijing epoch peak Science and Technology Ltd. production.
When this programme four stratotype cloudy-surface release papers are made, can spoon at a side surface of release liners original paper layer 1 the first leaching membrane layer 2, side surface spoons the second leaching membrane layer 4 in addition.Described the first leaching membrane layer 2 and the second leaching membrane layer 4 are laminated polyester film.Again in opposite side surface-coated one deck mist-surface release agent coating 3 of the first leaching membrane layer 2.Mist-surface release agent coating 3 is the adhesive of isolating on the adhesive tape, make it and the release liners bonding, so require its not with adhesive generation cross-linking reaction, the material main component that it uses is silicone oil.This programme has not only solved release liners original paper layer 1 and has lacked protection; easily suction is made moist curling problem is occured; employing is mixed with the mould release of mist agent the concavo-convex decorative pattern on release liners body paper surface is filled up even; can obtain peeling force stable, and so that the cloudy-surface release paper that organic pressure-sensing glue glue face reflecting effect is low, mist degree is effective.
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.
