Description
Technical field
The present invention relates to CABLE MATERIALS field, be specifically related to a kind of silicone hydride crosslinked non-halogen flame-proof polyvinyl chloride granula for cable.
Background technology
Electric wire is important materials indispensable in industrial and agricultural production and the modern life, China is that the electric wire of whole world maximum is produced country, wires and cables industry occupies very important status in the national economy of China, but, at present, CABLE MATERIALS on market exists non-refractory, not ageing-resistant, and after weathering test, the phenomenon that becomes fragile of turning to be yellow appears in material.Electric wire fire aging and that cause is also more and more, how to reduce the incidence of fire and presence of fire time mortality ratio, low cigarette, Halogen, the developing direction that fire-retardant, environmental protection also becomes wires and cables industry.Wherein the demand of halide-free smokeless silicone hydride crosslinked non-halogen flame-proof polyvinyl chloride granula for cable is increasing, the production of halide-free smokeless silicone hydride crosslinked non-halogen flame-proof polyvinyl chloride granula for cable is in polyolefin substrate, to add a large amount of Shawinigan blacks or Shawinigan black to reach flame retardant effect mostly at present, yet, adding of a large amount of inorganic materials, physical and mechanical properties and the processing of CABLE MATERIALS have been affected.Fire-retardant, low cigarette, environmental protection, good weatherability, the CABLE MATERIALS that cost is low become the direction of CABLE MATERIALS development.
Summary of the invention
The invention provides a kind of silicone hydride crosslinked non-halogen flame-proof polyvinyl chloride granula for cable and preparation method thereof.The cable being processed into by CABLE MATERIALS of the present invention has good mechanical property, and thermotolerance, good insulation preformance also have aging resistance good, the feature such as fire-retardant, environmental protection.
The technical solution used in the present invention is:
A kind of silicone hydride crosslinked non-halogen flame-proof polyvinyl chloride granula for cable, it is characterized in that, by the component raw material preparation of following weight part, obtained: polyvinyl chloride (PVC) RESINS 70-80, vinylformic acid meets an acrylic resin modified 10-20, acetate butyl 1-2, Trifluoroacetic Acid Ethyl Ester 1-3, zinc borate 8-10, molybdic oxide 2-3, cupric oxide 1-2, magnesium hydroxide 10-12, ammonium polyphosphate 8-10, triethyl citrate 6-10, fumarate 4-5, TCEP flame-retardant plasticizer (three (β-chloroethyl) phosphoric acid ester) 10-15, calcium zinc stabilizer 1-2, calcium stearate 1-2, Zinc Stearate 0.2-0.3, light calcium carbonate 8-10, talcum powder 3-5, calcinated argil 8-10, magnesiumcarbonate 3-4, glass microballon 0.2-0.3, two octadecanol ester 1-2, polyethylene wax 1-2, tribasic lead sulfate 0, 2-0.5, water-ground limestone 20-30, barium stearate 3-5, dibasic lead stearate 0.5-0.8, vinyltriethoxysilane 0.5-1.0, modified filler 8-10,
