Cold-resistant flame-retardant rat-proof and termite-proof communication cable

Abstract

The invention discloses a cold-resistant flame-retardant rat-proof and termite-proof communication cable. The cable comprises the following components by weight: 10-15 parts of silicone rubber, 15-20 parts of fluorinated silicone rubber, 10-15 parts of fluororubber, 3-7 parts of epoxy oil, 2-4 parts of a rare earth complex, 1-2 parts of lubricating oil, 5-15 parts of decabrominated dipheny ethane, 2-8 parts of antimonous oxide, 10-20 parts of traditional Chinese medicine extract, 2-5 parts of o-isopropylphenyl-n-methylcarbamate, 1-2 parts of paraffin, 0-5 parts of calcined clay and 1-3 parts of an antioxidant, wherein the traditional Chinese medicine extract is mixed extract of salvia japonica thunb., vervain, zanthoxylum bungeagum maxim and radix angelicae. The cable is good in cold resistance, high in tensile strength, easy to bend, convenient to construct and good in flame retardance; and the cable can be effectively prevented from being bitten by rodents, is good in rat-proof and termite-proof effects, is not cracked by frost under an outdoor low-temperature condition, ensures stable operation of communication lines, and avoids the phenomenon of an influence on operation of the communication lines caused by damage to the communication cable due to external environmental factors.

Description

technical field [0001] The invention relates to the field of cables, in particular to a cold-resistant, flame-retardant, rodent-proof and ant-proof communication cable. Background technique [0002] The service life of the communication cable is longer, the communication distance is longer, the capacity is large, the quality is high, stable and reliable, and the confidentiality is good. It can be opened for telephone, telegraph, fax and data transmission. Because the cables are installed outdoors, they are often damaged due to low temperature, humidity or the gnawing of rodents, which affects signal transmission; in addition, the flame retardancy of communication cables is also a problem that needs to be paid attention to. When the cable burns, it releases a large amount of Smoke, poisonous and corrosive gases are dangerous factors in fires, which cover people's safe evacuation and fire fighting work in fires. Therefore, enhancing the flame retardancy of communication cables...

[0002] The service life of the communication cable is longer, the communication distance is longer, the capacity is large, the quality is high, stable and reliable, and the confidentiality is good. It can be opened for telephone, telegraph, fax and data transmission. Because the cables are installed outdoors, they are often damaged due to low temperature, humidity or the gnawing of rodents, which affects signal transmission; in addition, the flame retardancy of communication cables is also a problem that needs to be paid attention to. When the cable burns, it releases a large amount of Smoke, poisonous and corrosive gases are dangerous factors in fires, and the safe evacuation and fire fighting work of flipping people in a fire, therefore, enhancing the flame retardancy of communication cables is an issue that needs to be studied at present
