Description
Technical field
The present invention relates to and a kind ofly wrap up the special flame-retardant insulating material of cable, belong to insulating material field.
Background technology
Flame retardant cable, refers to that sample is burned under regulation experimental condition, after removing test burning things which may cause a fire disaster, flame spread only in limited range, residual flame or residual to burn in limiting time can the cables of self-extinguish.Basic characteristic is: be likely burned in case of fire and can not run, but can stop spreading of the intensity of a fire.Generally, electric wire, just in case catch fire, can be limited in subrange burning, not produce and spread, keep other various equipment, avoid resulting in greater loss.At present, along with improving constantly of scientific and technological level, fire-retardant problem by the halogen flame retardant in past, further develop low halogen, Halogen flame-retarded.ZhongLi Science Group Co., Ltd is when development and production " communication power supply flame-retardant refractory flexible electric cable ", the insulation of cable, sheath be have employed to low smoke and zero halogen, decomposition temperature are high, the halogen-free polymeric material of good mechanical property, due to cable not halide and metal oxide, pernicious gas and a large amount of smog can not be produced when burning, there is not the possibility that can cause " secondary disaster ", and there is good mechanical performance and electric property, meet the instructions for use of cable, change the weak point of flame retardant cable in the past.
But, increased year by year by the fire electrically caused, and the fire wherein caused due to electric wire reason occupies sizable ratio, the fire that electric wire causes is normally due to protective coverings of cable aged deterioration, its insulating properties is caused to decline, cause caused by cable short circuit, also have plenty of and cause caused by cable generation electric arc explosive combustion because contact resistance is excessive in cable, and the intensity of a fire is along the harmfulness further increasing fire that spreads of cable line, such as Chinese patent CN 103489521 A discloses a kind of heat-proof combustion-resistant insulated cable, comprise insulating barrier, screen and conductor, it is characterized in that, described insulating barrier uses 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 selects crosslinked polyethylene, described conductor material selects copper content to be greater than the oxygen-free copper of 99.95%, its advantage has good anti-flammability and thermal endurance, meet market to the high performance demand of insulated cable, its shortcoming is in insulating barrier, add the material of flame-retardant composition, affect fire-retardant quality and flame retardant effect.And for example Chinese patent 200810020767.5 discloses a kind of flame-proof soft vinyl plastics for electric wire and cable, comprise fire proofing, be made up of the raw material of following weight: Corvic, plasticizer, stabilizer, fire retardant A, fire retardant B, fire retardant C, filler and lubricant are formed, its advantage has excellent fire resistance, oxygen index can reach more than 46, the electric wire that can meet special flame-retardancy requirements makees the instructions for use of sheath or insulating material, lose the significant fire resistance of tool, and there is good anti-low temperature brittleness performance, and there is good flexibility and good processing characteristics.Its shortcoming is that raw material adds complexity, and expensive, also has certain danger in raw material use procedure.
