Abstract
The invention discloses a highly flame-retardant TPE (Thermoplastic Polyurethane Elastomer) material which is used for a power supply wire sheath with VW-1 requirements, a USB (Universal Serial Bus) connecting wire, a headphone cable, a program-control cable, a data cable, an exchanger cable, a power cable, a civil cable and a marine aspect as well as an injection-molding piece of a corresponding product. The highly flame-retardant TPE material disclosed by the invention is modified by using SEBS, PP (Propene Polymer), metallocene and white oil as a main body, and added with special modified PPO (Polyphenylene Oxide) and a nitrogen-phosphor flame retardant. A phenomenon that the existing TPE cannot be burnt and separated out is solved. The material is not only excellent in performance, but also environment-friendly, so that competitive power is gained for China enterprises in European and American markets.
Description
Technical field
The TPE material that the present invention relates to a kind of high flame retardant, belongs to technical field of chemical products.
Background technology
At present, increasing people pays close attention to environmental protection, PVC product is because of halogen-containing, during burning, the hydrogen halide of emitting is larger to person injury, when facing fire, do not burn to death, but smoked extremely by poison gas, so the production of Halogen goes to be inevitable for PVC. just say at present, with low smoke and zero halogen EVA, be not that to be made with that high flame retardant requires be unrealistic, mainly that EVA thermal distortion is large. and the product that the low smoke and zero halogen EVA of irradiation is not, after irradiation, can not reclaim, cause the wasting of resources and environmental pollution. what the domestic TPE of carrying out was fire-retardant at present is almost blank, only have in the world GE to buy crying, cost is so high that cannot to accept. the present invention solved not halogen-containing and low smoke and zero halogen inaccessiable aspect, reduced cost, expanded use range, in European & American Market competition, won the market share to Chinese Enterprise.
The UL standard about electric wire quality of formulating according to safety of America testing laboratory (Underwriters Laboratories Inc), electric wire coated material must meet following basic demand: (1) has good flame retardant resistance, coated material is conventionally with testing vertical flammability (VW-1), matched plug material is evaluated with UL94V0 method, that UL standard is one of strict, (2) good electrical insulating property, (3) good thermotolerance, under hot environment, can keep good thermal change type, good low-temperature performance, guarantees cable not embrittlement cracking at low temperatures; According to electric wire practical service environment, require better resistance to deterioration.
Low molecular halogen-free flame retardants to ooze that wash rice goes wrong be also urgent need to solve the problem, some are disclosed in many patents for the composition of electric wire and cable material, said composition is SEBS, poly-the third combustion, polyolefin elastomer, phosphoric acid ester halogen-free flame retardants forms jointly, this material is in mechanical property, aging resistance has better advantage, does not exist phosphoric acid ester to belong to micromolecular material, and surperficial infiltration migration can not produce yet.
Summary of the invention
For the technical problem of above-mentioned existence, the present invention proposes a kind of TPE material of high flame retardant. technical solution of the present invention is achieved in that
Fire retardant mechanism of the present invention, polyphenylene oxide PPO, phosphoric acid salt (containing hypophosphite) is mainly done from putting out function; nitrogenated flame retardant (melamine class); the give vent to anger concentration that not reduces oxygen of release stops and to prolong combustion, and oxyhydroxide discharges water outlet, reduces the temperature of point of ignition; zinc borate is mainly responsible for allowing point of ignition volume become large; nano imvite, ceramic fine bead, hydrotalcite; allow point of ignition crust rapidly, generate protective layer.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Flame retardant properties of the present invention is high, does not separate out.
Embodiment
1, phosphoric acid salt (containing hypophosphite) 1%-60%, polyphenylene oxide PPO 1%-60%, nitrogenated flame retardant (melamine class), 1%-60% oxyhydroxide (aluminium hydroxide, magnesium hydroxide, calcium hydroxide) 1%-20%, zinc borate 1%-20%, nano imvite 1%-20%, ceramic fine bead 1%-20%, hydrotalcite 1%-20%.
2, after above-mentioned materials is mixed with stirrer, make TPE combustion inhibitor special.
4,, by the material in above-mentioned 3, after mixing with stirrer, double-screw extruding pelletizing, is processed into a kind of TPE material of high flame retardant.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
