Description
Technical field
The present invention relates to a kind of high-strength fireproof cold-resistant electric wire cable.
Background technology
Polyvinyl chloride, English abbreviation PVC is the thermoplastic resin being polymerized under initiator effect by vinyl chloride.It is the homopolymers of vinyl chloride.Ryuron and vinyl chloride copolymer system are referred to as vinyl chloride resin.PVC is the white powder of impalpable structure, and the degree of branching is smaller.Industrial PVC molecular weight is general in the range of 50,000~120,000, with larger polydispersity, the reduction of molecular weight with polymerisation temperature and increase；Without definite melting point, 80~85 DEG C start to soften, and 130 DEG C are changed into viscoelastic state, and 160~180 DEG C start to be changed into viscous state；There are preferable mechanical performance, tensile strength 60MPa or so, 5~10kJ/m2 of impact strength
；There are excellent dielectric properties.But the stability to light and heat is poor, more than 100 DEG C or through long-time exposure in sunshine, will decompose and produce hydrogen chloride, and further autocatalysis is decomposed, cause discoloration, physical and mechanical properties also declines rapidly, stabilizer is must be added in actual applications to improve the stability to light and heat.PVC is very hard, and dissolubility is also very poor, can only be dissolved in the minority solvent such as cyclohexanone, dichloroethanes and tetrahydrofuran, and organic and inorganic acid, alkali, salt are stablized, and chemical stability is reduced with the rising of temperature in use.PVC is dissolved in acetone-carbon disulfide or Acetone-Benzene mixed solvent, and fiber is formed for dry spinning or wet spinning, claims polyvinyl chloride fibre, with fire retardant, acid and alkali-resistance, antimicrobial, wear-resisting characteristic and with preferable warmth retention property and elasticity.
Fire prevention (fire resisting) cable refers to that, when there is fire, can guarantee that a class cable of circuit integrality；This cable ensure that cable continues normally to provide electric power and the various signals of transmission in a long time, so as to be that control fire and lifesaving provide safeguard in high temperature of fire
；Public arena or important place especially for densely populated places such as theater, subway, airport, nuclear power stations is very meaningful.According to the difference of refractory material used, existing fire-resisting cable is divided into mica tape fire-resisting cable and the class of mineral insulation fire-resisting cable two.This two classes fire-resisting cable can reach A classes (test temperature is 950 DEG C~1000 DEG C) refractory standard, it is ensured that the integrality of circuit during fire, but both cable qualitys are big, and speed of production is slow, high cost.The common method of silicon rubber flame-retardant is to adding fire retardant in high polymer, to reduce comburant surface temperature, dilution combustible molecular concentration, cut off the supply of oxygen, barrier layer is formed in silicon rubber burning surface, prevent heat energy from being transmitted to silicon rubber depth, suppress temperature and raise to reach fire-retardant purpose；But the cable that flame retardant rubber is made can only delay rubber to be burnt till the time of powder, if continued by baked wheaten cake, rubber just gradually becomes powdery and comes off, and loses protective effect, and electric wire causes short circuit by breakdown.
