Description
Technical field
The invention belongs to shading technical field of membrane, and in particular to a kind of selfreparing photomask.
Background technique
Photomask is widely used in automobile, building and electronics field, and slight breakage occurs in photomask at present
After be unable to that self-regeneration, heat-proof quality is poor, service life is short, and photomask uses also not convenient enough, idle storage at present
It is not convenient enough.
The information disclosed in the background technology section is intended only to increase the understanding to general background of the invention, without answering
When being considered as recognizing or imply that the information constitutes the prior art already known to those of ordinary skill in the art in any form.
Utility model content
The technical problem to be solved by the present invention is overcoming the problems in above-mentioned background technique, a kind of selfreparing shading is provided
Film.
To achieve the above object, the technical solution adopted in the utility model is as follows:
A kind of selfreparing photomask, including protective shell and shading membrane body, it is characterised in that: the protective shell includes protection
Shell, fixed bracket and upper cover, the protection shell and fixed frame bottom connection, are an integral molding structure, outside the protection
It is cavity structure between shell and fixed bracket, is provided with cutter groove on the protection shell；
The shading membrane body is located in the cavity between protection shell and fixed bracket, and the shading membrane body is from upper cause
Under be followed successively by protective layer, super-hydrophobic coat, carbon black coating, thermal insulation layer, thermoplastic polyurethane (TPU) layer, adhesive layer and release layer.
Further, the super-hydrophobic coat with a thickness of 0.01 μm -10 μm.
Further, the carbon black coating layer thickness is 10-50 μm.
Further, the thermal insulation layer with a thickness of 5-10 μm.
Further, thermoplastic polyurethane (TPU) layer is with a thickness of 10 μm -100 μm.
The utility model having the beneficial effect that compared with the existing technology:
(1) a kind of selfreparing photomask of the utility model, the protection shell of protective shell and fixed bracket are integrally formed,
It protects and places shading membrane body between shell and fixed bracket, protect design on shell to have cutter groove, when it is desired to be used by shading
Film extracts cutting along cutter groove, and when not needing in use, covering upper cover, photomask is placed in protective shell, it is not easy to it damages, when
It is finished when needing replacing, opens upper cover and replaced, it is easy to use.
(2) the utility model is provided with super-hydrophobic coat in carbon black coating surface, which is occurring slightly to scrape
It is able to carry out self-regeneration when rubbing, improve the service life of photomask while being provided with thermal insulation layer below carbon black coating, increases
The heat-proof quality of photomask is added.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
As shown in Figure 1-3, a kind of selfreparing photomask, including protective shell 1 and shading membrane body 2, the protective shell 1 include
Shell 11, fixed bracket 12 and upper cover 13, the protection shell 11 and fixed 12 bottom connection of bracket are protected, be integrally formed knot
Structure is cavity structure between the protection shell 11 and fixed bracket 12, is provided with cutter groove 14 on the protection shell 11；
The shading membrane body 2 is located in the cavity between protection shell 11 and fixed bracket 12, the shading membrane body 2
Protective layer 21, super-hydrophobic coat 22, carbon black coating 23, thermal insulation layer 24, thermoplastic polyurethane (TPU) layer are followed successively by under upper cause
25, adhesive layer 26 and release layer 27, wherein the super-hydrophobic coat 22 with a thickness of 0.01 μm -10 μm, 23 thickness of carbon black coating
Be 10-50 μm, thermal insulation layer 24 with a thickness of 5-10 μm, 25 layers of thermoplastic polyurethane (TPU) is with a thickness of 10 μm -100 μm.
