Abstract
The invention discloses a heat-resisting anti-flaming insulated cable which comprises an insulating layer, a shielding layer and a conductor. The insulating layer is made of anti-flaming polyvinyl chloride insulating materials and comprises, by weight, 40-50% of polyvinyl chloride, 10-20% of plasticizer, 35-45% of fire retardant, 0.5-1.5% of antioxygen and 0.4-1% of stabilizer. The shielding layer is made of crosslinked polyethylene, and the conductor is made of oxygen-free copper with the copper content lager than 99.95%. In this way, the heat-resisting anti-flaming insulated cable has good fire resistance and heat resistance, and meets the demand of markets for high performance of insulated cables.
Description
Technical field
The present invention relates to the insulating material field, particularly relate to a kind of heat-proof combustion-resistant insulated cable.
Background technology
In recent years along with the fast development of China's economy, by the electric fire increasing year by year caused, and the fire wherein caused due to the electric wire reason occupies sizable ratio, the fire that electric wire causes is normally due to the protective coverings of cable aged deterioration, cause its insulating properties to descend, cause due to cable short circuit, also have plenty of because in cable, contact resistance is excessive and cause due to cable generation electric arc explosive combustion, and the intensity of a fire has cable heat-resisting, fire resistance and has become active demand along the harmfulness that has more increased fire that spreads of cable line so a kind of.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of heat-proof combustion-resistant insulated cable, has thermal endurance and anti-flammability, the demand of satisfying the market to the High Performance Insulation cable.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of heat-proof combustion-resistant insulated cable is provided, comprise insulating barrier, screen and conductor, described insulating barrier is used flame-retardant polychloroethylene insulation material, its composition and weight proportion are: polyvinyl chloride 40%-50%, plasticizer 10%-20%, fire retardant 35%-45%, antioxidant 0.5%-1.5%, stabilizer 0.4%-1%, described screen is selected crosslinked polyethylene, the oxygen-free copper that described conductor material selects copper content to be greater than 99.95%.
In a preferred embodiment of the present invention, described plasticizer is selected o-phthalic acid dibutyl ester.
In a preferred embodiment of the present invention, described fire retardant is selected antimony oxide.
In a preferred embodiment of the present invention, described antioxidant is selected antioxidant 1010 and irgasfos 168.
The invention has the beneficial effects as follows: a kind of heat-proof combustion-resistant insulated cable of the present invention has good anti-flammability and thermal endurance, and satisfying the market is to the high performance demand of insulated cable.
