RUBBER COMPOUND FOR ELECTROSTATIC DISSIPATIVE RUBBER PRODUCTS AND METHOD OF PRODUCING THE RUBBER COMPOUND

摘要

A rubber compound for the manufacture of electrostatic dissipative products comprising a rubber component derived from poly(butadiene-co-acrylonitrile), an electrically conductive filler component derived from sulfonic acid doped polyaniline, and an antioxidant, wherein the mixture comprising the rubber component, electrically conductive filler and antioxidant is vulcanised by exposure to electromagnetic radiation, and the vulcanised rubber compound possesses improved conductivity and tensile strength properties. A method for producing the rubber compound above comprising of providing a rubber component derived from poly(butadiene-co-acrylonitrile), an electrically conductive filler component derived from sulfonic acid doped polyaniline, and an antioxidant, then mixing the rubber component, electrically conductive filler and antioxidant together. The mixture is then moulded into a suitable shape and then subjected to an electromagnetic radiation to stimulate vulcanisation of the rubber mixture.
