Embodiment Construction

[0017] The structure of the present invention will be further described below in conjunction with the drawings.

[0018] Such as figure 1 As shown, the metal composite belt of the present invention is a composite structure of a copper layer or aluminum-plastic layer 1 and a biaxially stretched halogen-free flame-retardant polynylon composite material layer 3. The copper layer or aluminum-plastic composite material layer 1 and a halogen-free flame-retardant nylon composite material layer 3 It is formed by bonding and heating the adhesive layer 2. The halogen-free flame-retardant nylon composite material has a scratch-resistant and wear-resistant layer.

[0019] In the present invention, the metal layer 1 is obtained by cold rolling, the total thickness of the composite belt is 0.028 to 0.308 mm, wherein the thickness of the metal layer 1 is 0.02 to 0.2 mm, and the biaxially oriented halogen-free flame-retardant nylon composite material layer 3 The thickness is 0.008-0.058mm, and th...

Abstract

The invention relates to the field of power cables and concretely relates to a copper-plastic composite belt for power cables. The composite belt coats the outer surface of the power cable, is orderly provided with a metal layer 1, a glue layer 2, a halogen-free flame retardant material layer 3 and a scratch-resistant wear-resistant layer 4. The above layers are bonded to form a composite structure through heating bonding. The halogen-free flame retardant material layer is a nylon composite material layer.

Description

Technical field [0001] The invention relates to the field of power cable outer tapes, in particular to a halogen-free flame-retardant copper-plastic or aluminum-plastic composite tape suitable for power cables. Background technique [0002] Copper-plastic or aluminum-plastic composite tape is an alternative to pure copper tape for power cables, and is one of the important varieties of modern copper processing materials, and its application in the power cable industry is continuously increasing. At present, the production standard of copper-plastic composite tape generally refers to YD / T723.4-2007, that is, pure copper tape is used as the base material, and the thickness is above 0.1mm. The plastic film uses ethylene copolymer or polyethylene plastic film, and the thickness is above 0.05mm. , The tensile strength of the plastic film is ≥15MPa. However, in actual operation, due to factors such as bending and scratching, the plastic layer is often damaged. However, in actual appl...
