Problems solved by technology

[0003] In the electrical field, rubber materials can be used as the sheath of wires and cables, which have high requirements for the insulation of rubber, and also have high requirements for the strength and heat resistance of rubber. In order to improve the performance of rubber, now rubber When refining, a large amount of white carbon black is often added to reinforce the rubber. However, white carbon black has a low density and is easy to raise dust. It is easy to generate dust pollution during use and transportation, and it is easy to cause harm to the health of workers.

Abstract

The invention relates to a method for preparing an anti-aging cable sheath. The method comprises the following steps: (1) mixing butadiene styrene rubber, cis-polybutadiene and chlorinated polyethylene, adding silicon micropowder, carbon black, epoxy soybean oil, anti-aging agent AW, nano-titanium dioxide, attapulgite, chlorinated paraffin and magnesia spinel, and mixing for 2-3 minutes; (2) vulcanizing; and (3) extruding. According to the method, the existing formula of rubber materials is changed, the insulating performance and high temperature resistance of rubber can be improved.

Description

technical field [0001] The invention belongs to the field of high-performance materials, relates to the field of rubber, and in particular relates to a preparation method of an aging-resistant cable sheath. Background technique [0002] Wire and cable are used to transmit electric (magnetic) energy, information and wire products to realize electromagnetic energy conversion. In the broad sense, wires and cables are also referred to as cables for short. In the narrow sense, cables refer to insulated cables, which can be defined as: a collection composed of the following parts; one or more insulated cores, and their respective possible coatings. Protective layer and outer sheath, the cable may also have additional uninsulated conductors. [0003] In the electrical field, rubber materials can be used as the sheath of wires and cables, which have high requirements for the insulation of rubber, and also have high requirements for the strength and heat resistance of rubber. In ord...
