Technical field
The utility model relates to the cable technology field, is specifically related to a kind of cable that is used for elevator.
Background technology
At present, elevator commonly used both at home and abroad generally is divided into two types with the retinue control cable, and promptly copper core polyvinyl chloride insulation pvc sheath elevator uses retinue control cable and low smoke halogen-free flame-retardant polyolefin class insulating sleeve elevator with the retinue control cable.
Copper core polyvinyl chloride insulation pvc sheath elevator uses the insulating sleeve material of retinue control cable to be thermoplastics type's pvc material; Though this material has elasticity and flexibility preferably; But; This material is in the process that fabrication and processing is produced, and heavy metal element compounds such as palpus interpolation lead must use organic compounds such as PBBs (ether), chlorinated paraffin wax as flame-retardant plasticizer as stabilizer.The cable of these material manufacture can cause severe contamination to environment; After this cable comes into operation in elevator; In case breaking out of fire can contain toxic gases such as halogen, after human body sucks these toxic gases in the gas that its burning produces; Will cause death by suffocation in a short period of time, reduce personnel escape's chance in the fire.In addition, be easy to generate the gas that contains corrosivity compositions such as halogen during owing to fire, can cause corrosion, produce quadratic loss building, equipment, instrument etc.
Low smoke halogen-free flame-retardant polyolefin class insulating sleeve elevator has fire-retardant Halogen low toxicity and does not contain heavy metal element and PBBs characteristics such as (ethers) with the retinue control cable; Under the situation of meeting fire; It is few to have the amount of being fuming; Toxic gas content such as halogen is low, and cable reclaims in the future and scraps convenient processing, the advantages such as secondary pollution that can not cause environment.But the elasticity and the flexibility of said material are relatively poor; For insulation and the flexibility of sheath material and the anti-flammability of elasticity and cable that guarantees cable; Must in the insulation and sheath material of cable, add ethylene-vinyl acetate copolymer (EVA elastomer), ethylene-octene copolymer (POE metallocene elastomer modifier), Al (OH) in a large number
3(fire retardant), Mg (OH)
2(fire retardant) not only increased material cost, also reduced the mechanical property of materials.
