Problems solved by technology

[0003] The wire and cable industry in the traditional technology mainly uses PVC as the coating material of cables, but PVC and bromine-containing flame-retardant wires and cables produce a lot of toxic smoke and corrosive gases during the combustion process, which will accelerate the suffocation of people on the fire scene and increase the rescue difficulty of rescuers; and the corrosive gas released will cause the fire site and nearby electrical appliances to be corroded and scrapped; in addition, halogenated flame retardants are used in production, transportation, storage, application, and recycling of waste products. Toxic accumulation and carcinogens are produced in the process

preparation example Construction

[0035] The preparation method of halogen-free thermoplastic elastomer cable material for electric vehicle charging pile cable includes the following steps:

[0036] (1) Weigh the elastic composite material and polypropylene in proportion, mix them evenly in a high-speed mixer, granulate by a twin-screw extruder, and prepare for use;

[0037] (2) Weigh polyolefin resin, polycarbonate, epoxy resin, halogen-free flame retardant and antioxidant in proportion, put into a high-speed mixer to mix evenly, and add a twin-screw extruder with a temperature of 130 to 160 ° C to mix Refining and granulating, spare;

[0038] (3) Weighing the remaining materials in proportion, adding the pellets obtained in steps (1) and (2) into a high-speed mixer and mixing uniformly, then at a temperature of 130-150 ° C and a screw speed of 300-400 r / min The twin-screw extruder is kneaded and granulated to obtain the halogen-free thermoplastic elastomer cable material for electric vehicle charging pile c...

Abstract

The invention provides a halogen-free thermoplastic elastomer cable material for an electric vehicle charging pile cable. The cable material comprises the following raw materials in parts by weight: 20-40 parts of an elastic composite material, 10-20 parts of polypropylene, 15-35 parts of polyolefin resin, 5-15 parts of polycarbonate, 5-15 parts of epoxy resin, 5-10 parts of polyoxyethylene ether, 15-35 parts of a halogen-free flame retardant, 15-25 parts of a compatilizer, 1-5 parts of a coupling agent, 1-5 parts of an auxiliary agent and 3-9 parts of an antioxidant. According to the invention, the impact resistance of polypropylene is poor, and after the elastic composite material is added, a crazing-shear band caused by elastic particles can fully play a role, so that the impact resistance of the mixed material is remarkably improved, and the impact resistance and structural strength of the cable material are favorably improved when the mixed material is used for preparing the cable material; the cable material disclosed by the invention has the advantages of environmental protection, low smoke amount, no halogen, no corrosive gas and the like.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a halogen-free thermoplastic elastomer cable material for electric vehicle charging pile cables. Background technique [0002] Wire and cable is an indispensable and important material in industrial and agricultural production and modern life. my country is the largest wire and cable producer in the world, and the wire and cable industry occupies a very important position in my country's national economy. Thermoplastic elastomer, also known as "third-generation rubber", has excellent mechanical properties and processing properties, excellent weather resistance, and is an excellent cable material. [0003] The wire and cable industry in the traditional technology mainly uses PVC as the covering material of the cable, but PVC and bromine-containing flame-retardant wire and cable generate a lot of toxic smoke and corrosive gas during the combustion process, which will accele...
