Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a write the technical field of membrane, especially glue the technical field of magnetism write membrane.
[ background of the invention ]
The traditional paper of current official working general use can not used repeatedly, can cause timber wasting of resources, is unfavorable for the environmental protection, so a lot of enterprises have researched and developed the membrane of writing that can used repeatedly, but the membrane of writing on the market is mostly smooth surface, and the definition is not satisfactory with writing the sense of touch, not only carries inconveniently, still need use glue to paste when using, leads to installation, change very inconvenient.
[ Utility model ] content
The utility model aims at solving the problem among the prior art, providing a glue magnetism and exempt from to paste membrane of writing, can promote the definition greatly and write the sense of touch, adsorbable on the iron sheet, convenient to carry, and easy installation, change to can used repeatedly, resources are saved.
In order to realize the above purpose, the utility model provides a glue magnetism and exempt from to paste writing membrane, include polyester film, paste layer and flexible glue magnetic layer, paste the layer and be located polyester film and flexible glue magnetic layer surface in opposite directions, polyester film and the last surface evenly distributed who pastes the layer back of the body mutually have a plurality of bellying, the surface that has roughness is formed to this upper surface.
Preferably, the thickness of the polyester film is 90 to 160 μm.
Preferably, the upper surface of the polyester film has a surface roughness of 1.5 to 3.5 μm.
Preferably, the adhesive layer is a microporous adhesive layer.
Preferably, the thickness of the micropore adhesive layer is 20-50 mu m, and the micropore density is 1000-3000 per cubic centimeter.
Preferably, the thickness of the soft rubber magnetic layer is 100-200 μm.
Preferably, the convex part is hemispherical.
Preferably, a plurality of hemispherical convex parts are uniformly distributed on the convex part.
The utility model has the advantages that: the glue magnetic paste-free writing film improves the touch feeling, the viewing visual angle range and the definition of writing of the writing film through the plurality of the bulges uniformly distributed on the upper surface of the polyester film; the hemispherical bulges are added on the surfaces of the bulges on the upper surface of the polyester film, so that the hydrophobicity of the writing film is increased, and the writing projection film has easy wiping property; the soft rubber magnetic layer added on the other side of the polyester film can be directly adsorbed on the iron sheet, accessories such as a bracket and the like are omitted, glue is not needed, the cost is saved, the installation and the transportation are convenient, and the soft rubber magnetic layer has the advantages of no residual colloid, high reusability, convenience in carrying and the like.
The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.

In the figure: 1-polyester film layer, 2-sticking layer, 3-soft glue magnetic layer, 11-convex part and 12-hemispherical convex part.
[ detailed description ] embodiments
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Example 1: the utility model provides a glue magnetism and exempt from to paste and write membrane, includes polyester film 1, pastes layer 2 and flexible glue magnetic layer 3, paste layer 2 and be located polyester film 1 and flexible glue magnetic layer 3 surface in opposite directions, polyester film 1 and the upper surface evenly distributed who pastes layer 2 mutually on the back of the body have a plurality of bellying 11, form a surface that has roughness at this upper surface. The thickness of the polyester film 1 is 90 μm. The roughness of the upper surface is 1.5 mu m. The sticking layer 2 is a micropore adhesive layer. The thickness of the micropore adhesive layer is 20 mu m, and the micropore density is 1000/cubic centimeter. The thickness of the soft rubber magnetic layer 3 is 100 μm, and the convex part 11 is hemispherical.
Example 2: the utility model provides a glue magnetism and exempt from to paste and write membrane, includes polyester film 1, pastes layer 2 and flexible glue magnetic layer 3, paste layer 2 and be located polyester film 1 and flexible glue magnetic layer 3 surface in opposite directions, polyester film 1 and the upper surface evenly distributed who pastes layer 2 mutually on the back of the body have a plurality of bellying 11, form a surface that has roughness at this upper surface.
