Embodiment 1

[0017] Mix 100g of polypropylene, 40g of polyvinyl chloride, 10g of asbestos, 25g of nitrile rubber, 1g of stabilizer, 2g of plasticizer and 2g of antioxidant and melt it (the melting temperature is 150°C and the time is 10min) to obtain a molten liquid M; the flame retardant wire sheath A1 is obtained after the molten liquid M is molded by an extruder.

Embodiment 2

[0019] Mix 100g of polypropylene, 50g of polyvinyl chloride, 20g of asbestos, 35g of nitrile rubber, 5g of stabilizer, 6g of plasticizer and 7g of antioxidant and then melt it (the melting temperature is 200°C and the time is 15min) to obtain a molten liquid M; the flame retardant wire sheath A2 is obtained after the molten liquid M is molded by an extruder.

Embodiment 3

[0021] Mix 100g of polypropylene, 45g of polyvinyl chloride, 15g of asbestos, 30g of nitrile rubber, 3g of stabilizer, 4g of plasticizer and 5g of antioxidant and then melt it (the melting temperature is 160°C and the time is 12min) to obtain a molten liquid M; the flame retardant wire sheath A3 is obtained after the molten liquid M is molded by an extruder.

Abstract

A flame retardant wire coat and a preparing method thereof are disclosed. The method includes mixing polypropylene, polyvinyl chloride, asbestos, butadiene-acrylonitrile rubber, a stabilizer, a plasticizer and an antioxidant, then melting the mixture to obtain a melt liquid M, and molding the melt liquid M through an extruding machine group to obtain the wire coat. Problems that flame retardance of insulating coats of common wires is poor, and once short circuits or other situations occur, the insulating coats are liable to be on fire are overcome by the wire coat and the method.

Description

technical field [0001] The invention relates to the field of wire production, in particular to a flame-retardant wire sheath and a preparation method thereof. Background technique [0002] The wire is composed of one or several soft wires, covered with a light and soft sheath; the cable is composed of one or several insulated wires, and the outside is covered with a tough outer layer made of metal or rubber. Cables and wires are generally composed of three parts: core wire, insulating sheath and protective sheath. Generally, the insulating sheath of electric wires has poor flame retardancy, and once a short circuit occurs, the insulating sheath is easy to catch fire. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a flame-retardant wire sheath and its preparation method, which solves the problem that the insulation sheath of general electric wires has poor flame-retardant performance, and the insulation sheath i...
