Instrument signal cable for controlling computer

Abstract

The invention discloses an instrument signal cable for controlling a computer. The instrument signal cable comprises a cable core and a jacket layer covering the outer side of the cable core; the jacket layer is prepared from the following raw materials in parts by weight: 100 to 110 parts of main materials, 1.5 to 2.5 parts of tert-butyl hydroperoxide, 2 to 4 parts of lauric acid, 1 to 2 parts oftetramethyl thiuram disulfide, 20 to 30 parts of heavy calcium carbonate, 15 to 25 parts of talcum powder, 45 to 55 parts of expanded perlite, 2 to 4 parts of melamine resin, 35 to 45 parts of cottonand linen fiber, 3 to 7 parts of plasticizer, 2 to 4 parts of antioxidant 1010, 1 to 2 parts of ultraviolet absorbent UVP-327, and 0.5 to 1.5 parts of light stabilizer GW-540. The instrument signal cable for controlling the computer is good in bend resistance and pulling resistance, high in tear strength, capable of preventing the direct contact between oxygen or vapour and a carbon chain, capable of effectively improving the hot oxygen stability and the aging resistance, and long in service life.

Description

technical field [0001] The invention relates to the field of cable technology, in particular to an instrument signal cable for computer control. Background technique [0002] Instrument signal cables for computer control are used in computer-based automatic control systems to transmit analog and digital signals such as detection, control, interlocking, and alarming of process variables in production devices. [0003] The existing instrument signal cables are often bent and pulled easily during use. Over time, the skin of the cable is easily broken, resulting in the failure of the instrument to work normally. Once a fault occurs, the instrument needs to be repaired. It takes a long time, seriously affects the actual production efficiency, and causes certain losses to the factory. Contents of the invention [0004] Based on the technical problems existing in the background technology, the present invention proposes an instrument signal cable for computer control, which has ...
