Abstract

The invention relates to the field of cable belts, in particular to a copper-plastic composite belt suitable for a communication cable and an optical cable and preparation thereof. The copper-plastic composite belt is coated on the outer surface of the communication cable or the optical cable and sequentially comprises a red copper layer (1), an adhesive layer (2) and a polyester film layer (3), wherein the red copper layer (1), the adhesive layer (2) and the polyester film layer (3) are bonded and heated to form a composite structure. The tensile strength of the copper-plastic composite belt is larger than or equal to 180MPa, the elongation at break of the copper-plastic composite belt is larger than or equal to 15%, the interlayer peeling strength between a copper belt and a plastic layer is larger than or equal to 15N / cm, the conductivity of the copper-plastic composite belt is larger than or equal to 90% IACS, and no punchthrough happens on the single side of the copper-plastic composite belt 1 kvd.c,1min.

Description

technical field

[0001] The invention relates to the field of cable tapes, in particular to a halogen-free flame-retardant copper-plastic composite tape suitable for communication cables and optical cables and its preparation. Background technique

[0002] Copper-plastic composite tape is a substitute for pure copper tape for cables. It is one of the important varieties of modern copper processing materials, and its application in the communication cable and communication optical cable industries is continuously increasing. At present, the production standard of copper-plastic composite tape generally refers to YD / T 723.4-2007, that is, pure copper strip is used as the base material, the thickness is above 0.1mm, and the plastic film is made of ethylene copolymer or polyethylene plastic film, and the thickness is above 0.05mm. The tensile strength of the plastic film is ≥15MPa. Further thinning the base material of the pure copper strip, thereby reducing the total thickness ...
