A method for preparing a uniformly-cured solid loading tire from a high-modulus graphene oxide/natural rubber composite is provided. A high-modulus graphene oxide/carbon black/natural rubber mixture sheet and two high-viscosity graphene oxide/carbon black/natural rubber mixture sheets are prepared, where a weight ratio of graphene oxide to natural rubber to carbon black to an interface modifying agent to an anti-aging agent to an antioxidant to a vulcanization accelerator to an activator to a softener to a vulcanizing agent is 0.5-5:100:40-120:1-20:1-10:1-10:1-20:1-20:1-20:1-20. The high-modulus rubber mixture sheet is sandwiched between the two high-viscosity rubber mixture sheets to form a sandwich-structure rubber mixture laminate, which is then processed into a strip. The strip is wound along a surface of a hub of a loading wheel, and then the hub is transferred to a mold for vulcanization to obtain the desired tire.

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.
