Embodiment 1

[0049] Embodiment 1 discloses a preparation method of a high temperature resistant flame retardant computer cable, comprising the following preparation steps:

[0050] Step a: use a wire drawing machine to stretch the copper rod to obtain a copper wire, and then anneal the copper wire to obtain a conductor. The steps specifically include:

[0051] First put the copper wire into the heating furnace and heat it to 560-670°C and keep it warm for 2-3 hours;

[0052] Then stop heating the heating furnace, let the copper wire cool down to 300-350°C with the heating furnace;

[0053] Then the copper wire is taken out from the heating furnace, cooled naturally to normal temperature to obtain a conductor;

[0054] Step b: twisting the conductors of 20 to each other to obtain a guide core;

[0055] Step c: Use an extruder to extrude a layer of insulating layer on the outside of the guide core, then wrap a layer of shielding layer on the outside of the insulating layer, and finally wr...

Abstract

The invention discloses a high temperature resistant and flame retardant computer cable and a preparation method thereof. The preparation method comprises the preparation steps of a, carrying out drawing and annealing to obtain conductors; b, mutually twisting the conductors to obtain conductor cores; c, extruding an insulating layer outside each conductor core by adopting an extruding machine, then wrapping a shielding layer outside the insulating layer, and finally wrapping a fire resistant layer outside the shielding layer to obtain a wire core; d, mutually twisting the wire cores around the outer surface of a reinforcement core to obtain a cable core; e, wrapping a filling layer; f, wrapping an inner wrapping belt layer; g, extruding a fireproof layer; h, wrapping an outer wrapping belt layer; and i, extruding an outer sheath layer. The preparation method carries out improvement in allusion to the existing computer cable preparation method so as to improve the problems such as poorhigh temperature resistance, poor flame retardance, low structural strength and short service life of the existing computer cable. The computer cable prepared according to the invention is high in structural strength and long in service life and has excellent high temperature resistance and flame retardance.

Description

technical field [0001] The invention relates to the technical field of computer cables, in particular to a high temperature resistant flame retardant computer cable and a preparation method thereof. Background technique [0002] Computer cables are one of the special cables for electronic computer systems. They are urgently needed supporting products for modern industrial construction. They are widely used in electronic computers, instruments and meters, various Signal transmission and control system for automatic detection equipment and other information processing equipment. These fields require computer cables to be able to transmit electric energy stably for a long time. The materials of existing computer cables are mostly flammable rubber or plastics. Therefore, the existing computer cables are insufficient in high temperature resistance and flame retardancy. When working in a high-temperature environment, the outer sheath and insulation layer of the cable will melt an...
