Abstract

The invention discloses a wear-resistant rubber sleeve for an aerospace cable and a preparation method thereof. The preparation method comprises the following steps: 1) mixing carbon black with sodiumpolystyrenesulfonate to prepare modified carbon black; 2) mixing the modified carbon black with calcium fluoride to prepare a mixture M1; 3) mixing natural rubber, polyurethane resin, dicumyl peroxide, t-butyl peroxypivalate, the mixture M1, stearic acid and an antiageing agent to prepare a rubber material; and 4) mixing and smelting the rubber material prepared in the step 3) and extruding and forming the rubber material to prepare the wear-resistant rubber sleeve for the aerospace cable. By modifying the carbon black with sodium polystyrenesulfonate, mixing the modified carbon black with calcium fluoride, mixing the mixture with the natural rubber, polyurethane resin, dicumyl peroxide, t-butyl peroxypivalate, stearic acid and antiageing agent and mixing and smelting the rubber materialand extruding and forming the rubber material, the rubber sleeve prepared by the material and method has better properties such as wear resistance.

Description

technical field [0001] The invention relates to the field of cable rubber sleeves for aerospace, in particular to a tear-resistant rubber rubber sleeve for aerospace cables and a preparation method thereof. Background technique [0002] As an indispensable power facility in production and life, cables are used in a wide range of fields, and they are also indispensable in aerospace and other fields. However, when used in the above-mentioned environment, the requirements for the cable are often higher, and the requirements for the rubber sleeve used to protect the core are also higher. However, general rubber sleeves are often difficult to be better used in the aerospace field due to their limited performance. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a tear-resistant rubber rubber sleeve for aerospace cables with better performance such as tear resistance and better strength and the like and a preparation method thereof.
