This material has good flame retardance and excellent mechanical properties.

Description

technical field [0001] The invention relates to the technical field of computer cables, in particular to a flame-retardant computer cable sheath material with excellent mechanical properties. Background technique [0002] With the promotion of computers, computer communication cables are used more and more widely. The role of computer cables is to transmit non-electrical control or transmission control signals to certain equipment and instruments of the computer. The emergence of computer cables solves the problems of weak transmission signals, signal interference, and signal distortion. The equipment and instruments can operate normally according to the instructions. For the normal operation of computers, how to prepare a cable sheathing material for computer systems with flame retardancy and good mechanical properties has become a technical problem to be solved at present. Contents of the invention [0003] The invention provides a flame-retardant computer cable sheathi...
