Description
Technical field
The present invention relates to a kind of cable flame-proof elastomer, the thermoplastic flame-proof elastomerics that particularly a kind of glass for cable strengthens.
Background technology
Polyolefin elastomer material has good processing characteristics and elasticity, is well suited for makeing the various starting material of extruding wire rod sheath.But because polyolefin elastomer material has stronger combustibility, with the electric wire of its making, when after surrounding environment presence of fire, flame can, along cable rapid spread to whole circuit, cause spreading and expanding of flame.Therefore, should select the flame-retardant electric wire and cable containing fire retardant.Fire retardant is mainly divided into organic fire-retardant and inorganic combustion inhibitor, halogen containing flame-retardant and halogen-free flame retardants at present.Organic fire-retardant is some fire retardants take compounds such as bromine system, phosphorus nitrogen system, nitrogen system and encapsulated red phosphorus as representative, and inorganic is mainly the flame-retardant systems such as antimonous oxide, magnesium hydroxide, aluminium hydroxide, silicon system.
Wherein halogenated flame retardant, flame retardant effect few, with low cost with its addition significantly and be used widely, once occupied critical role in fire retardant polyolefin cable Application Areas.But this type of Halogen flame-retardant cable amount of being fuming in the time of burning is large, can produce macro-corrosion gas and toxic gas, gives fire extinguishing, flees from and resume work and bring very large difficulty, and cause secondary harm.Therefore, consider from the aspect such as security and the feature of environmental protection to select low-smoke non-halogen flame-retardant agent to be applied to cable.
Thermoplastic elastomer is a kind of thermal-arrest thermoplastic plastic and rubber premium properties type material, its moulding separately, also can not use any binding agent, be coated on securely on the plastic materials such as PP, PE, PS, ABS, PC with quadric injection mould or forcing machine co-extrusion method, thereby make inner rigid polymer skeleton, skin is soft elastomeric goods.Therefore be widely used in the handle of family, toy and various tool, to reach both flexible, rigidity, anti-skidding feel, have again the effect of heat insulation, damping, damping, insulation, can alleviate user's sense of fatigue.Due to thermoplastic elastomer composition of raw materials, proportioning difference, so its performance is different.
Chinese patent application (publication number: CN1765984A) relates to a kind of thermoplastic elastomer (s) and preparation method thereof, this resilient material has adopted using SEBS as basic raw material, the thermoplastic elastomer that to comprise two or more SEBS, softening agent, thermoplastic polyurethane, compatilizer and oxidation inhibitor, inorganic mineral be raw material.The compatilizer of selecting due to this resilient material does not have specific aim, only improve the consistency of this material with general polar material, and for nylon, especially having added a large amount of glasses does the nylon strengthening, without any effect, so this material is only suitable in being used in the quadric injection mould bonding of ABS.
Chinese patent application (publication number: CN1931919A) discloses a kind of and nylon material secondary injection adhering thermoplastic elastomer, and this elastomerics raw material and weight percent thereof consist of: matrix resin 10 %-60 %, extending oil 5 %-60 %, tackifier 5%-50%, mineral filler 0%-25%, coupling agent 0.1%-0.8%, processing aid 0.1%-2%, one package stabilizer 0.1 %-2 %.Although this thermoplastic elastic material and common nylon adhesive are firm, but because the tackifier in this elastomerics have adopted at least one in nylon-type polymkeric substance, polar resin, if tackifier adopt nylon-type polymkeric substance, and this material itself do not have other increase nylon-type polymkeric substance and formula in the composition of matrix resin consistency, cause the finished product physicals poor, range of application is less; Even if adopt the technical scheme of polar resin or polar resin and nylon-type combination of polymers, also can cause the nylon under high glass fibre filling to lack good consistency, thereby greatly reduce bond effect, even cannot bond successfully.
In view of the good plasticity of elastomerics, ductility and modification regulating power, can either protect fully the wire rod of cable, can also improve the security of cable and install and use performance by modification simultaneously.
