Wire bundle with strong comprehensive property for automobile electric part

Abstract

The invention discloses a wire bundle with strong comprehensive property for an automobile electric part. The wire bundle is prepared from the following raw materials in parts by weight: 86 to 109 parts of natural rubber, 34 to 59 parts of polyvinyl chloride, 1 to 5 parts of sodium dodecyl benzene sulfonate, 8 to 15 parts of methyl triethoxysilane, 6 to 10 parts of dibutyl phthalate, 7 to 12 partsof N-cyclohexyl-N-phenyl-p-phenylenediamine, 3 to 8 parts of hydroxyethyl hexahydrotriazine, 5 to 9 parts of methyl tert-butyl ether, 3 to 8 parts of magnesium hydroxide, 11 to 15 parts of polylacticacid, 2 to 6 parts of barium myristate, 1 to 4 parts of barium stearate, 1 to 5 parts of barium laurate, 2 to 6 parts of calcium tetraborate, 2 to 5 parts of zinc undecenoate, 8 to 14 parts of silicapowder, 3 to 7 parts of white carbon black, 3 to 6 parts of urea phosphate, 2 to 7 parts of copper abietinate, 7 to 11 parts of high-temperature activated bamboo charcoal powder, 1 to 4 parts of organic solvent, 1 to 4 parts of anti-aging agent, 1 to 3 parts of sulfur, and 13 to 20 parts of paraffin oil. The wire bundle has good abrasion-resistant property, good hydrolysis-resistant property andchemical agent-resistant property, good insulation property, acid and alkaline-resistant property, compressive property and stripping property, and stable physical and chemical properties.

Description

technical field [0001] The invention relates to the technical field of wire harnesses, in particular to a wire harness for steam and electrical components with strong comprehensive performance. Background technique [0002] Automotive wires, also known as low-voltage wires, are different from ordinary household wires. Ordinary household wires are copper single-core wires with a certain hardness. The automotive wires are all copper multi-core flexible wires, some of which are as thin as hair, and several or even dozens of soft copper wires are wrapped in plastic insulating tubes (polyvinyl chloride), which are soft and not easy to break. [0003] Due to the particularity of the automotive industry, the manufacturing process of automotive wiring harnesses is also more special than other ordinary wiring harnesses. 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 r...

Problems solved by technology

[0004] With the increase of automobile functions and the widespread application of electronic control technology, there will be more and more electrical components, more and more wires, and the wiring harness will become thicker and heavier, and the ambient temperature around the engine in the car is high and corrosive There are also many gases and liquids. Therefore, the automotive wiring harness is required to have high temperature resistance, oil resistance, vibration resistance, and friction resistance. The comprehensive performance of the wiring harness in the prior art needs to be strengthened.
