Problems solved by technology

However, silicone rubber itself will continue to burn when it encounters an open flame, and the cables made of it have the defects of unsatisfactory heat resistance and flame retardancy, which limits its application in various fields of the national economy, especially for flame retardancy. When required, it is often necessary to modify it

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a graphene-modified silicone rubber cable sheath material. Background technique [0002] Silicone rubber is a kind of cross-linkable and curable polymer elastomer with Si-O bond as the main chain and organic groups (such as methyl, vinyl, phenyl, etc.) connected to Si atoms as side chains. Because silicone rubber has excellent high and low temperature resistance and anti-aging properties, it can be used for a long time in a wide temperature range (-50 ° C ~ 200 ° C), and has been widely used in electronics, machinery, automobiles, chemicals, aviation, It is widely used in aerospace, shipbuilding and other fields, and it is also a commonly used material in the cable field. However, silicone rubber itself will continue to burn when it encounters an open flame, and the cables made of it have the defects of unsatisfactory heat resistance and flame retardancy, which limits it...
