Abstract

The invention discloses a high strength automobile tail wire harness and a preparation method thereof. The preparation method comprises: 1) subjecting bentonite, a diazonium salt, tributyltin, and triethyl silicon to contact reaction in an organic solvent under an alkaline condition, and then performing filtering to obtain a modified activator; 2) mixing natural rubber, silicon micropowder, N-cyclohexyl-N-phenyl-p-phenylenediamine, di-tert-butyl-p-cresol, lignin, urea phosphate, 2-methylanthracene, methyl tertiary butyl ether, trimethoprim, methyltriethoxysilane, ammonium chromic alum and the modified activator to obtain masterbatch; 3) mixing a vulcanizing agent, sulfur and the masterbatch to conduct first vulcanization treatment; 4) subjecting the masterbatch subjected to the first vulcanization treatment to second vulcanization to prepare modified rubber; and 5) carrying out extrusion molding on the modified rubber on a wire core surface so as to form the high strength automobile tail wire harness. The wire harness has excellent mechanical properties and high temperature resistance.

Description

technical field [0001] The invention relates to an automobile wire harness, in particular to a high-strength automobile tail wire harness and a preparation method thereof. Background technique [0002] Rubber is an elastic polymer. Rubber can be obtained from the sap of some plants, or it can be man-made. Both have quite a lot of applications and products, such as tires, gaskets, etc., and have become important economic crops. Rubber plantations are mainly concentrated in Southeast Asia, such as Thailand, Malaysia, and Indonesia. Rubber is divided into natural rubber and synthetic rubber according to raw materials. Both natural rubber and synthetic rubber are widely used in production and life. [0003] Because natural rubber has a series of excellent physical and chemical properties, especially its excellent resilience, insulation, water resistance and plasticity, it can be widely used: such as rain boots, warm water bags and elastic bands used in daily life; Surgeon glo...
