Abstract

The invention belongs to the technical field of a composite material used for a communication product, and especially relates to a high-strength insulating material for communication cables. The high-strength insulating material comprises the following component in parts by weight: 60-70 parts of chlorinated polyethylene rubber; 4-7 parts of sodium stearate; 20-28 parts of cellulose fiber; 9-12 parts of sodium bicarbonate; 15-18 parts of polyethylene terephthalate; 6-9 parts of sodium dodecylbenzene sulfonate; 4-6 parts of N-N'-methylenebisacrylamide; and 10-14 parts of benzoate. The modifiedcellulose fiber with low cost is used as a reinforcing material, which greatly reduces the production cost, and the material has high mechanical strength, and can be widely used.

Description

technical field [0001] The invention belongs to the technical field of composite materials for communication products, in particular to a high-strength insulating material for communication cables. Background technique [0002] Communication cables are generally composed of conductors, insulation, shielding, sheath, and armor; the insulation is used to support and separate the conductors so that each pair of conductors constitutes an electrical circuit for transmitting signals; the insulating material should have good electrical insulation, high It has a certain mechanical strength, a certain degree of flexibility, and is easy to process; commonly used insulating materials are paper (paper rope, paper tape, pulp), rubber and plastic (polyvinyl chloride, polyethylene, polystyrene, polytetrafluoroethylene, polyvinyl chloride, etc.) Propylene, etc.); most modern telecommunication cables are insulated with various high-quality plastics or plastics and air. [0003] Chinese pate...
