Communication cable sheath material and preparation method thereof

Abstract

The invention discloses a communication cable sheath material, which is composed of the following raw materials in parts by weight: 50-70 parts of polypropylene, 20-30 parts of EPDM rubber, 10-20 parts of isopropanol, and methyl acetoacetate 10~15 parts, 15~25 parts of urea-formaldehyde resin, 10~25 parts of silicone resin, 20~30 parts of chlorinated polyethylene rubber, 4~8 parts of zinc stearate, 2~10 parts of calcium stearate, trioxide 4-9 parts of antimony, 1-4 parts of vaseline, 5-10 parts of magnesium oxide, 0.5-5 parts of antioxidant and 1-6 parts of anti-aging agent. The communication cable sheath material is selected reasonably, has good insulation performance, corrosion resistance, waterproof and airtight performance, and has the advantages of high transmission stability, good confidentiality, simple preparation process, low production cost, and long service life.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a communication cable sheath material and a preparation method thereof. Background technique [0002] Communication cables are cables that transmit electrical signals such as telegrams, fax documents, and television signals. Compared with overhead open wires, communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and less affected by natural conditions and external interference. Most of the communication cables currently on the market have shortcomings such as unstable transmission, poor insulation performance, poor anti-shock performance, and short service life. Therefore, it is urgent to change the original sheath material formula to enhance the overall performance of the cable. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, and provides a communication c...
