A high flame retardant and anti-interference medical cable

Abstract

The present invention specially relates to an anti-interference medical cable with high inflaming retarding. The cable comprises a cable inner core, an aluminum foil shielding layer, a composite insulation layer, a high temperature resistance layer, a protection layer and a wearing layer which are arranged from the inside to outside in order in a vertical direction. Insect prevention coating filmsare sprayed on the composite insulation layer and the protection layer, the composite insulation layer and / or the protection layer is prepared by the following raw materials by the parts by weight: 100 parts of polyvinyl chloride, 31-36 parts of polytetrafluoroethylene micro powder, 44-49 parts of perfluoroalkoxy copolymer, 15-25 parts of ethylene-trifluorochloroethylene copolymer, 30-35 parts ofcomposite compatibilizer, 20-30 parts of nano-zinc oxide, 10-15 parts of para-aramid fibers and 10-15 parts of modified magnesium hydroxide. The medical cable is high in inflaming retarding, high anti-interference capacity, is more excellent in mechanical property and electrical insulation property, can prevent from biting by rats and ants, and is longer in life and safe and reliable in usage.

Description

technical field [0001] The invention relates to the field of cable manufacturing, in particular to a highly flame-resistant and anti-interference medical cable. Background technique [0002] Wire and cable are indispensable and important materials in industrial and agricultural production and modern life. my country is the world's largest producer of wire and cable. The wire and cable industry occupies a very important position in my country's national economy. Wires and cables mainly include conductors, shielding layers, insulating layers and sheaths. The insulating layers and sheaths are usually made of polyvinyl chloride, polyethylene and other materials. Wires and cables made of these materials, especially medical cables, have flame retardant properties, The high and low temperature resistance performance is poor, and it is easy to be bitten by insects such as mice and termites during use, and the medical cable fails to use and shortens the service life.
