Problems solved by technology

Polyvinyl chloride has the advantages of low cost, convenient processing, excellent mechanical properties, corrosion resistance and excellent insulation. It is widely used in construction, light industry, chemical industry, electrical appliances, wire and cable and other fields. Both can transmit electric energy and transmit signals normally, and the existing PVC sheathed flexible cables are increasingly unable to meet the needs. If a kind of flexible cable with good toughness, high impact resistance, excellent tear resistance, good thermal stability and low cost is prepared Low and high-performance communication cables have become a technical problem that needs to be solved at present

Abstract

The invention discloses a high-performance communication cable. According to weight parts, 70-100 parts of PVC resin, 6-8 parts of linear low-density polyethylene, 5-10 parts of calcium-zinc composite stabilizer, and 1-1.5 parts of antimony trioxide are weighed. , 0.2-0.5 parts of stearic acid, 0.1-0.4 parts of phenolic antioxidant, 1.5-2 parts of acrylic resin, 1-1.5 parts of silicone powder are put into the mixer and stirred at low speed for 1-2min; then add 20-24 1 part of trioctyl trimellitate, 5-8 parts of dioctyl phthalate, 4-6 parts of epoxidized soybean oil, stirring at a medium speed for 2-3min, the stirring temperature is 95-105°C; then add heavy calcium carbonate Stir for 2-4 minutes; discharge the material, put it into a twin-screw extruder and extrude to obtain the above-mentioned sheath, and the extrusion temperature is 145-160°C. In the present invention, the above-mentioned high-performance communication cable has good toughness, high impact strength, excellent tear resistance, good thermal stability and low cost.

Description

technical field [0001] The invention relates to the technical field of communication cables, in particular to a high-performance communication cable. Background technique [0002] As we all know, with the rapid development of the national economy and the continuous renewal of power facilities, the use of various types of wires and cables has increased significantly, driving the demand for various types of cable materials, and there has been a relatively large increase in quantity, so the production cost of cable materials and quality put forward higher requirements. Polyvinyl chloride has the advantages of low cost, convenient processing, excellent mechanical properties, corrosion resistance and excellent insulation. It is widely used in construction, light industry, chemical industry, electrical appliances, wire and cable and other fields. Both can transmit electric energy and transmit signals normally, and the existing PVC sheathed flexible cables are increasingly unable ...
