Abstract

The invention relates to an anti-explosion polyvinyl chloride sheath material for mining cables and a preparation method thereof. The preparation method comprises mixing evenly polyvinyl chloride resin 100 parts by weight, plasticizer 30-80 parts by weight, stuffing 0-60 parts by weight, high-conductivity carbon black 10-40 parts by weight, anti-static agent 0-10 parts by weight, and other auxiliary agent 3-20 parts by weight by a high-speed mixer, extruding at 130-170 DEG C by a single- or double-screw extruder after being melted, water-cooling drawing bar or wind-cooling die-surface hot cutting and granulating, oven-drying, and packaging to obtain the finished product. Compared with the prior art, the invention has the advantages of excellent durable anti-static property and flame retardant property.

Description

technical field [0001] The invention relates to a sheath polymer material for electric wires and cables, and relates to a material for mine antistatic flame retardant cables with high safety requirements. Background technique [0002] Polyvinyl chloride is widely used because of its excellent mechanical and physical properties, flexibility, chemical resistance, low price, and easy processing. Due to its good electrical insulation, the soft PVC material has poor flame retardancy due to the addition of a large amount of flammable material, so its use in places with high safety requirements such as coal mines is limited. Contents of the invention [0003] The object of the present invention is to provide an explosion-proof polyvinyl chloride sheath material for mine cables with excellent antistatic properties and flame retardant properties in order to overcome the above-mentioned defects in the prior art. [0004] The purpose of the present invention can be achieved through ...
