Abstract

The invention provides a strong anti-aging cable sheathing material and a preparation method thereof, and relates to the technical field of cable sheath production. The cable sheathing material is prepared from the following raw materials, in parts by weight: 45-55 parts of silicone rubber, 20-25 parts of cis-polybutadiene, 10-15 parts of acrylate rubber, 8-12 parts of distearyl pentaerythrityl diphosphite, 2-3 parts of nano cerium dioxide, 0.6-1.0 part of a cross-linking agent, 6-8 parts of 2,6-tert-butyl-4-methylphenol, 3-5 parts of dithiodinglycol distearictate, 5-7 parts of diaryl p-phenylenediamine, 2-4 parts of diallyl phthalate, 2-4 parts of a vulcanizing agent, and 2-4 parts of a dispersing agent. The method provided by the invention overcomes the deficiencies in the prior art, andcan effectively improve the aging resistance of the sheathing material and prevent a cable from being aged under influence of external light, heat and oxygen, and the cable sheath has excellent overall performance, high safety and a long service life, and is suitable for promotion.

Description

technical field [0001] The invention relates to the technical field of cable sheath production, in particular to a strong aging-resistant cable sheath material and a preparation method thereof. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. An insulating covering used to connect electrical circuits, appliances, etc. The cable has the characteristics of internal electrification and external insulation. The outer covering of the cable conductor is the cable sheath, which is used to protect the inner conductor and prevent the user from getting an electric shock. [0003] At present, the formula composition and production process of the cable sheath material are unreasonable, resulting in poor aging resistance of the cable sheath material, so that the cable is easily aged under the influence of ...
