Embodiment 1

[0026] refer to figure 1 , a composite aluminum foil, including a first aluminum foil layer 1, a second aluminum foil layer 2 and a plastic reinforcement layer 3, the first aluminum foil layer, the plastic reinforcement layer and the second aluminum foil layer are arranged in sequence, and the adjacent layers are all composited by glue One, the surface of the second aluminum foil layer is also compounded with an adhesive layer 4, the adhesive layer is a maleic anhydride graft modified polyethylene adhesive film, and the adhesive layer and the second aluminum foil layer are combined by glue . The thickness of the adhesive layer is 0.020mm.

[0027] The plastic reinforcement layer is a PET polyester film with a thickness of 0.015mm.

[0028] The first aluminum foil layer and the second aluminum foil layer are alloy aluminum foils with a thickness of 0.009 mm.

Embodiment 2

[0030] The plastic reinforcement layer is a PET polyester film layer with a thickness of 0.020 mm. The first aluminum foil layer and the second aluminum foil layer are alloy aluminum foils with a thickness of 0.012 mm. The adhesive layer is a polyethylene adhesive film grafted and modified with maleic anhydride, with a thickness of 0.025 mm.

[0031] The following is a comparison table of low-cost high-adhesive performance aluminum foil and ordinary double-sided self-adhesive aluminum foil.

[0032]

[0033] From the above actual test results, it can be seen that the application of low-cost and high-adhesive aluminum foil significantly reduces the intermediate frequency temperature during sheath production, and thus improves the appearance and ovality of the aluminum foil, and the adhesive performance is also significantly increased.

Abstract

The invention relates to a composite aluminum foil, which comprises a first aluminum foil layer, a second aluminum foil layer and a plastic reinforcing layer, wherein the first aluminum foil layer, the plastic reinforcing layer and the second aluminum foil layer are sequentially arranged, the adjacent layers are respectively compounded together by glue, the surface of the second aluminum foil layer is compounded with an adhering layer, the adhering layer is a polyester adhering thin film, the polyester is grafted and modified with maleic anhydride, and the adhering layer is compounded with the second aluminum foil layer together by glue. The composite aluminum foil has the advantages that the common problem of design and manufacturing technique of a coaxial cable is solved, the quality stability and the suitability of the cable are improved, and the social benefits are obvious; the adhering performance of the cable product is improved, the cost is low, and the process property is favorably prompted to be further improved; and the technique of the composite aluminum foil plays a leading role in the industry and has a great promoting function for market broadening and brand promotion.

Description

(1) Technical field [0001] The invention relates to the field of wire and cable material processing, in particular, the invention is a composite aluminum foil with low cost and high adhesive performance. (2) Background technology [0002] The coaxial cable has been developed to the fourth generation, adopting the structural design of physical foam insulation plus self-adhesive aluminum foil for the outer conductor. Since the self-adhesive aluminum foil is designed with a plastic adhesive layer that can be heated and melted on the side close to the foam insulation, the self-adhesive aluminum foil is melted and bonded by induction heating when the sheath is extruded to form a closed longitudinal package structure, thereby improving the protection against heat. The moisture protection of the foam insulation greatly prolongs the service life of the cable. [0003] However, in the actual product manufacturing process, due to various factors such as the design of the aluminum foi...
