Abstract

The invention relates to the field of wire harness sheathing materials, and particularly discloses a high-and-low-temperature-resistant wire harness sheathing material of a new energy automobile. Thehigh-and-low-temperature-resistant wire harness sheathing material of the new energy automobile comprises the following components: 30-45 parts of thermosetting liquid polyimide pure resin, 20-35 parts of EVA resin, 10-15 parts of polytetrafluoroethylene, 4-6 parts of a temperature-resistant compound modifying agent, 6-10 parts of ultra-fine activated calcium carbonate, 3-5 parts of diisononyl phthalate, 2-4 parts of a lubricating agent and 0.5-0.9 part of an antioxidant. The thermosetting liquid polyimide pure resin, the EVA resin and the like are used as matrixes, the matrixes have properties of weather resistance, temperature resistance, wear resistance, corrosion resistance and the like, and then are compounded with the temperature-resistant compound modifying agent and the like, and thus, the properties (such as wear resistance, impact resistance, weather resistance, temperature resistance and corrosion resistance) of the prepared material are excellent.

Description

technical field [0001] The invention belongs to the field of new energy automobile spare parts, and in particular relates to a new energy automobile high and low temperature resistant wire harness sheath material and a preparation method thereof. Background technique [0002] The automobile wiring harness is the main body of the automobile circuit network, and there is no automobile circuit without the wiring harness. The wire harness refers to the contact terminal (connector) punched from copper and the wire and cable after crimping, and then plastic insulator or metal shell on the outside, and then bundled with wire harness to form a connected circuit component. The wire harness industry chain includes wire and cable, connectors, processing equipment, wire harness manufacturing and downstream application industries. Wire harnesses are widely used and can be used in automobiles, household appliances, computers and communication equipment, and various electronic instruments ...
