Problems solved by technology

Chinese patent CN200910110381.8 discloses a high heat-resistant, high-gloss, flame-retardant ABS modified material and its preparation method. The material includes ABS, SAN, flame retardant, heat-resistant agent, compatibilizer, and antioxidant And lubricants, this method has the advantages of simultaneously achieving high heat resistance, high flame retardancy and high gloss, but this method is very limited in improving the heat resistance of flame-retardant ABS, and the heat distortion temperature will not exceed 90°C. The thermal agent has a great influence on the mechanical properties, especially the notched impact strength will generally drop below 10

Abstract

The invention relates to the technical field of cable sheaths, and in particular relates to an ABS cable sheathing material and a processing technology thereof. The ABS cable sheathing material is prepared from the following raw materials in parts by weight: 72-90 parts of ABS resin, 6-15 parts of PC resin, 3-8 parts of a silicone flame retardant, 5-12 parts of an inorganic flame retardant, 3-10 parts of a compatilizer, 1-5 parts of polyethylene wax, 1-3 parts of vinyl tris (b-methoxyethoxy) silane, 20-40 parts of silica micropowder and 0.7-1.6 parts of an antioxidant. The invention improves the heat resistance and flame retardant performance of the material, and also improves the notch impact strength and tensile strength of the ABS cable sheath material.

Description

technical field [0001] The invention relates to the technical field of cable sheaths, in particular to an ABS cable sheath material and a processing technique thereof. Background technique [0002] ABS resin is a terpolymer composed of styrene, butadiene and acrylonitrile. It combines the high fluidity of styrene, the rubber toughness of butadiene and the chemical resistance of acrylonitrile. It has excellent processing performance, Low temperature resistance, electrical insulation, chemical corrosion resistance, high gloss and excellent electroplating performance, as well as excellent creep resistance, high dimensional stability, and low molding shrinkage, can be used as cable sheathing materials. Insulate and protect the cable core. [0003] However, on the one hand, the oxygen index of ABS resin is only 18%, which is a flammable material; on the other hand, the heat resistance of ABS resin itself is not high, and the general heat distortion temperature is 82-84°C (ASTM D...
