Abstract
The utility model discloses a copper-aluminium foil film composite belt, relating to a composite belt applied in electric wires, cables, electrical appliances and integrated circuits for shielding, electric conduction, heat conduction, connection and insulation. The copper-aluminium foil film composite belt comprises a metal foil and an insulating film layer; the metal foil comprises an electrolytic copper foil and an aluminium foil which are adhered together, wherein the surface of the outer-layer metal foil is plated with inert conductive metal. The copper-aluminium foil film composite belt has the following advantages that 1) a shielding layer, an electric-conducting layer and a heat conducting layer adopt two types of metallic combination (the copper foil and the aluminium foil) so as to achieve the effects of light structure proportion, low production cost, good shielding property, electrical conductivity and heat conductivity and the like; and 2) the metal foil adopts the electrolytic copper foil and the aluminium foil, the purity is larger than 99.8 percent, and in order to prevent oxidation, the surface of the copper foil is plated with a layer of inertia conductive metal.
Description
Technical field
The utility model relates to a kind of composite band that is applied to do in electric wire, cable, electrical equipment, the integrated circuit shielding, conduction, heat conduction, connection and insulation usefulness.
Background technology
The at present domestic composite band of making shielding, conduction, heat conduction, connection and insulation usefulness in electric wire, cable, electrical equipment, the integrated circuit that is used as is often selected Copper Foil for use, following defective is arranged: the 1) copper foil membrane of domestic production, be copper mostly through cold bundle, prolong pressure, high annealing forms, purity difference, became uneven (at present domestic prolonging pressed the most nearly 0.02mm of copper thickness), easily oxidation of surface, conduction, poor thermal conductivity; 2) density of copper is big, causes the quality of product overweight, has increased production and cost of transportation; 3) China's copper shortage of resources, annual a large amount of imports, the cost height of relying on.The someone has adopted Copper Foil and aluminium foil have been combined with each other for this reason, and is in addition comprehensive the advantage of Copper Foil and aluminium foil, has a better effect, but needs equally further to improve.
The utility model content
The utility model is at above-mentioned defective, and purpose is to provide a kind of premium properties that has, and can satisfy the composite band of different use occasions.
The technical solution of the utility model is: the utility model comprises metal forming and is bonded in the insulating film layer of metal forming one side that metal forming comprises electrolytic copper foil and the aluminium foil that is bonded together, wherein outer field metal foil surface plating inertia conducting metal.
Skin is an electrolytic copper foil, wherein one or more of electrolytic copper foil surface plating titanium, metal Ru, metal iridium, metal platinum, metal rhodium, metal tantalum.
Effects such as the utlity model has following advantage: two kinds of metallic combinations (Copper Foil and aluminium foil) are adopted in 1) its shielding, conduction, heat-conducting layer, reach the structure light specific gravity, and production cost is low, and shielding, electric conductivity, thermal conductivity are good.2) metal forming adopts electrolytic copper foil and aluminium foil, and purity＞99.8% for anti-oxidation, is coated with one deck plating inertia conducting metal at copper foil surface.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is that electrolytic copper foil, 2 is that aluminium foil, 3 is Kapton among the figure.
The specific embodiment
The utility model comprises metal forming and is bonded in the insulating film layer of metal forming one side that metal forming comprises electrolytic copper foil 1 and the aluminium foil 2 that is bonded together, wherein outer field metal forming (electrolytic copper foil) surface plating inertia conducting metal.
Skin is an electrolytic copper foil 1, wherein one or more of electrolytic copper foil 1 plating metal on surface titanium, metal Ru, metal iridium, metal platinum, metal rhodium, metal tantalum.
Further, insulating film layer of the present utility model is selected Kapton 3 for use, and Kapton 3 has the advantage of working range big (heatproof-260 ℃～+ 400 ℃, normal working temperature is at 300 ℃).
According to experiment, draw following experimental data:
| Title | Metal level | Technology | High annealing | Peel strength | Purity (%) | Non-oxidizability | Shielding, conduction, thermal conductivity | Proportion | Cost | Operating temperature |
| The cold rolling pressure copper foil membrane that prolongs | Copper Foil | Cold bundle prolongs pressure | 450-60 0℃ | Generally | ＜ 99.8 | Difference | Generally | Greatly | High | Less than 200 ℃ |
| The electrolytic copper foil film | Electrolytic copper foil | Electrolysis | Do not have | Fabulous | ＞ 99.8 | Fabulous | Excellent | Greatly | High | Greater than 200 ℃ |
| Novel titanizing cathode copper aluminium foil film | Electrolytic copper foil, aluminium foil | Electrolysis dry type composite algorithm | Do not have | Fabulous | ＞ 99.8 | Fabulous | Excellent | Gently | Low | 300 ℃ of-269～400 ℃ of operate as normal |
