Abstract
The utility model provides a shield plate with carbon containing PET film, includes carbon containing PET film, metal sheet, carbon containing PET film and metal sheet 2 is checked through the hot pressing of single face corona treatment, need not not the gluing agent can reach the adhesive strength of requirement with extra process, the corona treatment technique need satisfy following condition: the hot press moves with the upward pressure and with 10m's minute speed with temperature more than 200 degrees and 5 kilograms and carries out hot pressing, metal plate material gives first place to with the metal material that can electrically conduct. The beneficial effects of the utility model are that: the metal sheet that will have electromagnetism wave absorption function through the corona technique carries out hot -pressing composite with the carbon containing PET film that has the insulating radiation function, even electronic component and shield plate laminating can not take place the short circuit yet together, need not not make the product can carry out resistance and cut off at the inside electric tape that pastes of shield plate, also can carry out the electromagnetic wave shielding, simultaneously, use the corona technique also to avoid the practical of gluing agent and extra process, reduce the also miniaturization for being favorable to realizing the product of cost.
Description
Technical field
The utility model is related to a kind of barricade, more particularly to a kind of barricade with carbon containing PET film.
Background technology
Miniaturization, lightweight, operation simplification requirement recently as the development of electronic industry, particularly mobile phone and small household appliances product original paper is sharply increased, thus it requires electronic original part has integrated level higher, performance higher.
Electronic original part integrated level in electronic product increases, distance from each other is reduced, so as to cause electromagnetic wave density and heat density to increase.To solve this problem, generally using materials such as barricades and graphite with heat dispersion.It is the miniaturization for reaching product and light-weighted purpose; it is required that the spacing of barricade and electronic component is minimized; but the barricade of electromagnetic wave absorption is generally that conductive metal material is constituted; when electronic component and barricade come in contact; short circuit can be caused and cause the product cannot normal work; therefore insulating tape would generally be pasted inside barricade in subsequent handling; not only reduce radiating effect; also prevent the miniaturization of product and lightweight purpose from realizing well; extra operation causes that production efficiency is reduced, and cost increases.
For the above, it is necessary to reasonably be improved prior art.
Utility model content
For disadvantages described above, the utility model provides a kind of barricade with carbon containing PET film, and the metal with electromagnetic wave absorption function and the carbon containing PET film with insulation and heat sinking function are combined through one side sided corona treatment hot pressing.
To achieve the above object, the utility model uses following technical scheme：
A kind of barricade with carbon containing PET film, including carbon containing PET film, metallic plate；The carbon containing PET film is combined with metallic plate by one side sided corona treatment hot pressing, is the bonding strength that can reach requirement without adhesive and additional process.
Meanwhile, the corona treatment techniques need to meet following condition：Hot press carries out hot pressing with 200 degree of temperatures above and 5 kilograms of pressure above and with the speed movement of 10m/ minutes.
The carbon containing PET film, is rendered as black, with shading characteristic, and with heat dispersion higher, can not use graphite material, is conducive to controlling fee of material and improve production efficiency；PET film has insulating properties simultaneously so that electronic component and barricade fit together will not also be short-circuited in time.
The metallic plate, material, such as gold, silver, copper, for shielding electromagnetism involves maintenance planform, is made, or using alloys such as stainless steels or meet metallic plate based on conductive metal series using in above-mentioned material or the alloy material of more than two；Using based on nonmetallic materials the material as metallic plate after conducting function need to be obtained during material in outside applying conductive material.
A kind of barricade with carbon containing PET film described in the utility model has the beneficial effect that：
（1）Carbon containing PET film, with heat dispersion higher, it is possible to reduce not even using heat sink materials such as graphite, is conducive to controlling fee of material and improve production efficiency.Meanwhile, because PET film has insulating properties so that even if electronic component and barricade fit together will not also be short-circuited, without insulating tape is pasted inside barricade, reduce subsequent handling and cost, improve production efficiency.
（2）The metallic plate with electromagnetic wave absorption function and the carbon containing PET film with insulating radiation function are carried out into hot pressing by corona technology to be combined, product is carried out resistance cut-off, can also carry out electromagnetic wave shielding；Meanwhile, the practical and extra operation of adhesive is it also avoid using corona technology, it is also the miniaturization for being advantageously implemented product to reduce cost.
Brief description of the drawings
The utility model is described in further detail below according to accompanying drawing.
Fig. 1 is a kind of structural representation of the barricade with carbon containing PET film described in the utility model embodiment.
In figure：
1st, carbon containing PET film；2nd, metallic plate；
Specific embodiment
A kind of barricade with carbon containing PET film, including carbon containing PET film 1, metallic plate 2；The carbon containing PET film 1 is combined with metallic plate 2 by one side sided corona treatment hot pressing, is the bonding strength that can reach requirement without adhesive and additional process.
Correspondingly, the corona treatment techniques need to meet following condition：Hot press carries out hot pressing with 200 degree of temperatures above and 5 kilograms of pressure above and with the speed movement of 10m/ minutes.
The carbon containing PET film 1, is rendered as black, with shading characteristic, and with heat dispersion higher, can not use graphite material, is conducive to stationary material to take and improve production efficiency；PET film has insulating properties simultaneously so that even if electronic component and metallic plate fit together will not also be short-circuited.
The metallic plate 2, material, such as gold, silver, copper, maintenance planform is involved to shield electromagnetism based on conductive metal material, made using in above-mentioned material or the alloy material of more than two, or used alloy or the composite materials such as stainless steel；Using based on nonmetallic materials the material as metallic plate 2 after conducting function need to be obtained during material in outside applying conductive material.
It is above-mentioned be for the ease of those skilled in the art it will be appreciated that and apply this case technology, person skilled in the art obviously can make various modifications to these examples easily, and General Principle described herein is applied in other embodiments without by performing creative labour.Therefore, this case is not limited to above example, and, according to the announcement of this case, the improvement made for this case and modification all should be in the protection domains of this case for those skilled in the art.
