High-temperature resistant automobile air-conditioning wiring harness and preparation method thereof

Abstract

The invention discloses a high-temperature resistant automobile air-conditioning wiring harness and a preparation method thereof. The high-temperature resistant automobile air-conditioning wiring harness consists of two parts, namely a wiring harness shell and a thermal-insulating membrane, wherein the wiring harness shell consists of natural rubber, a PEEK (Polyetheretherketone) material and polyvinyl chloride; the thermal-insulating membrane consists of silicon carbide powder, a high-temperature resistant fiber, boron phosphide, polyethylene and a high-temperature adhesive. As the wiring harness shell is made of three raw materials, namely the natural rubber, the PEEK material and the polyvinyl chloride, as master batch, the strength of the wiring harness shell can be improved, and the preparation efficiency can be improved; the constitution components, namely the silicon carbide powder, he high-temperature resistant fiber, the boron phosphide, the polyethylene and the like, of the thermal-insulating membrane, are very good in thermal resistance, so that the thermal resistance of the prepared thermal-insulating membrane is improved; finally by using the high-temperature adhesive,the wiring harness shell and the thermal-insulating membrane can be well adhered, and due to a water cooling mode, the toughness of the thermal-insulating membrane can be ensured.

Description

technical field [0001] The invention relates to the field of automobile wiring harness preparation, in particular to a high temperature resistant automobile air conditioning wiring harness and a preparation method and preparation method thereof. Background technique [0002] The automobile wiring harness is the network main body of the automobile circuit, and there is no automobile circuit without the wiring harness. The wiring harness refers to the contact terminal (connector) punched from copper material and the wire and cable after being crimped, and then the outer plastic pressing the insulator or the external metal shell, etc., and the wiring harness is bundled to form a component that connects the circuit. The wiring 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, computer and communica...

AI Technical Summary

Problems solved by technology

[0003] The present invention studies the wiring harness of the automobile air conditioner. After a long period of use, the traditional wiring harness of the automobile air conditioner will cause difficulty in heat dissipation, which will lead to the melting of the wiring harness shell, resulting in safety problems such as electric leakage.
