Embodiment 1

[0014] Example 1: Weigh 8% of sodium antimonide inorganic flame retardant, 7% of solid plasticizer, and 1% of antioxidant in a high-speed mixer according to mass percentage, and mix for no less than 2 minutes; then weigh 50% Polyvinyl chloride resin, 25% flame retardant plasticizer, 5% decabromodiphenylethane flame retardant are poured into a high-speed mixer and mixed for no less than 3 minutes; then add 5% antimony trioxide and 6% in turn The stabilizer, 0.5% modifier and 0.5% release agent are mixed for no less than 3 minutes; the flame retardant plasticizer is tricresyl phosphate, and the solid plasticizer is "Am-168 solid plasticizer". The release agent is calcium stearate. The mixed material is added to a two-stage extruder and melt blended to prepare the composition for the high flame-retardant PVC cable outer sheath material of the present invention.

[0015] The obtained composition is vulcanized into a sheet in a vulcanizer, the vulcanization temperature is 160° C., an...

Abstract

The invention relates to a composition for a solid plasticized high-flame-retardant PVC (polyvinyl chloride) sheath material and a preparation method of the composition, and belongs to the technical field of cable materials. According to the composition and the preparation method, an Am-168 solid plasticizer and sodium antimonide flame retardant are introduced into the high-flame-retardant PVC cable sheath material; the traditional fire retardant damages other properties of the material while achieving the flame-retardant purpose; however, sodium antimonide does not affect body properties of the material while achieving the flame-retardant modification purpose due to a structure and constituent characteristics of sodium antimonide; the compatibility and adhesive strength with plastic are improved greatly; the dispersity is good; a loading level can be raised; the impregnating property is good; the mixing time is short; uniform flowing is realized in a mold; and forming is good. Mechanical properties of the material are improved, and the composite high-flame-retardant cable sheath material prepared by the composition for the composite high-flame-retardant cable sheath material has good mechanical properties and flame resistance.

Description

Technical field [0001] The invention relates to a composition for a solid plasticized high flame-retardant PVC sheath material and a preparation method thereof, and belongs to the technical field of cable materials. technical background [0002] Flexible PVC plastics for wires and cables have been mass-produced as a large category of PVC soft products. With the rapid development of the wire and cable industry, the varieties and use conditions of cable materials are getting higher and higher, especially for ships, In aviation and other work, the demand for high oxygen index flame-retardant cable materials is increasing. This product has already come out abroad. Some domestic manufacturers and scientific research units are discussing this product. However, due to the aging performance and flame retardant performance And process performance are unstable, especially the appearance of the pay-off line is dull, and there are particles that are difficult to plasticize, resulting in the ...
