Abstract

The invention discloses an antistatic cable insulation material and its preparation method. The antistatic cable insulation material contains, by weight, 100 parts of polydimethylsiloxane, 3-8 parts of a flexibilizer, 0.3-0.8 part of an antioxidant, 2-6 parts of asbestos powder, 1-2.2 parts of ferrocene, 10-15 parts of bentonite and 0.05-0.15 parts of rare earth oxide. The antistatic cable insulation material has excellent mechanical property and antistatic property.

Description

technical field [0001] The invention relates to pipe fittings, in particular to an antistatic cable insulation material and a preparation method thereof. Background technique [0002] The cable insulation material is an important part of the cable. It not only plays the role of insulation, but also plays the role of heat insulation and anti-corrosion. Once the insulation layer of the outer layer of the metal core is damaged, the cable will be greatly reduced. performance. At present, cable insulation materials are difficult to meet the actual needs in terms of antistatic. Contents of the invention [0003] The object of the present invention is to provide an antistatic cable insulating material and a preparation method thereof, through which the antistatic cable insulating material has excellent mechanical properties and antistatic properties. [0004] In order to achieve the above object, the present invention provides an antistatic cable insulation material, which cont...
