Preparation method of wear-proof stable communication cable material

Abstract

The invention discloses a wear-resistant and stable communication cable material, which is characterized in that it comprises the following components in parts by weight: high-density polyethylene HDPE 80-95, melamine formaldehyde resin 5-16, ammonium polyphosphate 1-2, dimethyl Base silicone oil 1‑2, epoxy butyl oleate 1‑2, tripolyglycerol monostearate 3‑5, glycerol triacetate 1‑2, stearic acid 0.3‑0.5, diphenyl-isooctyl phosphite Esters 1‑2. The preparation method of the invention is simple, the raw material formula is reasonable, the performance is greatly improved, and the wear resistance and stability are good.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a preparation method of a wear-resistant and stable communication cable material. Background technique [0002] A plurality of wires or conductors insulated from each other constitute a cable core, and a communication line with a sealed sheath on the outside. Some are also equipped with an outer sheath outside the sheath. There are various laying methods such as overhead, direct burial, pipeline and underwater. According to the structure, it is divided into symmetrical, coaxial and integrated cables; according to its function, it is divided into field and permanent cables (underground and submarine cables). The transmission frequency band of the communication cable is wider, the communication capacity is larger, and it is less affected by external interference, but it is not easy to repair. Can transmit telephone, telegram, data and image etc. [0003] The cable material is the...

AI Technical Summary

Problems solved by technology

Cable sheath materials include rubber, plastic, nylon and other varieties, all of which have their own excellent characteristics. For example, neoprene rubber has good physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, and Acid and alkali resistance, chemical reagents, high tensile strength, elongation and reversible crystallinity, good adhesion, aging resistance, heat resistance, oil resistance, chemical corrosion resistance, and can be used for a long time at 80 ~ 100 ° C It has a certain flame retardancy; it also has disadvantages, such as poor storage stability

Other sheath materials also have certain shortcomings, and as the application range of cables becomes wider and wider, the performance of sheath materials also needs to be improved
