The invention relates to ultralight graphene rubber foaming colloidal particles for shoe soles. The colloidal particles are prepared from, by weight, 60-65 parts of natural rubber, 8-12 parts of isoprene rubber, 8-12 parts of butadiene rubber, 6-8 parts of butadiene styrene rubber, 0.8-1.0 part of modified graphene, 0.08-0.12 part of poly N-vinyl acetamide, 0.8-1.0 part of silicone oil, 3.0-3.5 parts of inorganic nanoparticles, 1.2-1.5 parts of activated zinc oxide, 0.8-1.0 part of zinc stearate, 1.0-1.2 part of stearic acid, 0.8-1.0 part of a cross-linking agent, 2.0-3.0 parts of a flow assistant and 1.5-1.8 parts of a foaming agent. By adopting the ultralight graphene rubber foaming colloidal particles, the modified graphene is uniformly dispersed in all rubber materials, the rubber foaming colloidal particles have good heat stability, good abrasive resistance performance and good stretching intensity, the permanent compression deformation performance and the heat resistance shrinkage performance are improved, and 50% or above weight can be reduced.
