▎ 摘　　要

NOVELTY - Graphene oxide-supported rare earth vulcanization accelerator (I) is new. USE - (I) is useful in rubber composite material (claimed). ADVANTAGE - (I): can effectively improve the dispersion of rubber accelerator in rubber; enhances the interaction between graphene oxide and rubber molecular chains; increases the crosslinking density of rubber composites and improves the comprehensive properties of composites. DETAILED DESCRIPTION - Graphene oxide-supported rare earth vulcanization accelerator of formula (Rex(TC)y/GOz) (I) is new. Re = lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium or lutetium; TC = carbamodithioic acid-based ligand of formula (II); R, R' = methyl, ethyl, butyl, isopropyl, octyl, phenyl; X, Y, Z = mass fractions of Re, TC or GO; X = 15-30%; Y = 60-75%; and Z = 9-15%. INDEPENDENT CLAIMS are also included for: Preparation of (I); and Rubber composite material comprising rubber and (I).
