NOVELTY - Graphene modified support ring comprises 105-150 pts. wt. polyoxymethylene, 1-3 pts. wt. surface treatment agent, 15-25 pts. wt. carbon fiber, 1-5 pts. wt. filler, 2-6 pts. wt. plasticizer, 5-10 pts. wt. graphene , and 5-8 pts. wt. elastomer. USE - The graphene modified support ring is useful in the field of polymer composite material. ADVANTAGE - The graphene modified support ring: improves the mechanical properties, thermal stability, friction properties and rigidity of the composite material. The composite material: has good industrial application prospects market value, and worthy for promotion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing a graphene modified support ring comprises (1) performing surface treatment of carbon fiber and graphene with surface treatment agents, and (2) mixing the carbon fiber, graphene and polyoxymethylene, plasticizer, filler, and elastomer after the treatment in in proportion, and adding to the extruder for extrusion granulation.
