Description
Technical field
The invention belongs to field of cable technology, and in particular to a kind of environment-friendly cable Insulation Material and preparation method thereof, cable
Sheath.
Background technology
Electric wire is thread, as ignition source and linearly, flame spreads with the tendency of electric wire, water
Flat cable intensity of a fire burn rate is 3.5m/min, and vertical frame (well) electric wire vertical combustion speed reaches 8-9m/min.Therefore,
The burning of electric wire fire is rapid and unmanageable.According to statistics, electrical fire incidence and caused property loss occupy
First of all kinds of cause of fire, wherein, the fire for having more than 30% be by caused by electric wiring (electric wire) (data source in
Chinese fire protection yearbook in 2014).
Conventional CABLE MATERIALS is polyvinyl chloride, polyolefin low smoke and zero halogen material, rubber etc..But polyolefin low smoke and zero halogen material
Material, rubber cause mechanical performance and electrical property significantly to reach suitable fire resistance, it is necessary to add substantial amounts of fire retardant
Degree declines, and as China is in line with international standards, the PVC Insulation Materials and protective cover material of six kinds of metal element contents of limitation (meet European Union
RoHS is instructed) increasingly get the favour of people, and PVC material possesses good anti-flammability and cheap price, is still high
The preferred material of fire-resistant cable material.
At present, in terms of fire resistance, it is fire-retardant that standard GB/T/T19666-2005 defines ZA, ZB, ZC, ZD, Z five
Grade, can the division of flame retardant rating be to be determined by the single or bunchy testing vertical flammability of corresponding conditionses, and ZA is represented
Highest level.Because wire products structure only has conductor and insulating barrier, may can not be added as cable product by structure design
Realize A level fire resistances, wire products ZA level bunchy combustion experiments, it is necessary to reach by the fire resistance of insulating materials by force.
Common polyvinyl chloride flame retardant of plastic performance is generally that Z levels are fire-retardant, can not by the ZA levels of requirements of the national standard into
Beam combustion experiment, in fire, propagation of flame can be caused, high risks are caused to lives and properties and fire-fighting and rescue, if improved
The fire resistance of material, the on fire of electric wire would not be caused, run into external burning things which may cause a fire disaster, can also prevent the sprawling of the scorching fire of fire.Polychlorostyrene
Ethene did not had poison in itself, and poisonous is the various auxiliary agents added in plastics, is had to the environment such as soil, water source and health of human body
Harm.
