Abstract

The invention discloses an anti-aging automobile motor controller wire harness and a preparing method thereof. The method comprises the steps that firstly, bentonite, diazonium salt, tributyltin and vinyl triethoxysilane are subjected to a contact reaction in an organic solvent under the alkaline condition, and then filtering is carried out to obtain a modified activator; secondly, natural rubber, silica powder, N-cyclohexyl-N-phenyl-p-phenylenediamine, butylated hydroxytoluene, lignin, urea phosphate, 2-methyl anthracene, methyl tertiary butyl ether, trimethoprim, methyl triethoxysilane, ammonium chromic alum and the modified activator are mixed into rubber masterbatch; thirdly, a vulcanizing agent, sulfur and the rubber masterbatch are subjected to first-time vulcanization treatment; fourthly, the rubber masterbatch obtained after first-time vulcanization treatment is subjected to second-time vulcanization to form modified rubber; fifthly, the modified rubber is applied to the surface of a wire core through extruding formation to form the anti-aging automobile motor controller wire harness. The wire harness has excellent mechanical properties, high-temperature resistance and antibacterial performance.

Description

technical field [0001] The invention relates to an automobile wire harness, in particular to an anti-aging automobile motor controller 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; S...
