A vulcanizing agent-modified graphene prepared through an in-situ chemical deposition process and a controllable crosslinked natural rubber composite containing the same. In the preparation of the vulcanizing agent-modified graphene, graphene oxide is coated on a spherical thermal-conductive functional particle through the chemical bonding to obtain a 3D graphene particle; and a vulcanizing agent is adsorbed on the 3D graphene particle through π-π conjugation by an in-situ chemical deposition process to obtain a vulcanizing agent-modified graphene particle. Further, the vulcanizing agent-modified graphene particle is mixed with natural rubber latex, and undergoes synergistic coagulation in water to form a graphene masterbatch, which is further processed into the controllable crosslinked natural rubber composite by adding a certain amount of natural rubber block, rubber additive and reinforcing filler.
