Abstract:
      Natural latex was modified by graphene oxide，and the influence of graphene oxide dosage，vulcanization system and vulcanization process parameter on the strength properties of the vulcanized rubber film was studied using orthogonal experimental design. The results showed that，in the scope of the experiment，using tensile strength and tear strength as the optimization targets，the optimal solution of graphene oxide modified natural latex was 0.125 phr of graphene oxide，1 phr of sulfur，0.4 phr of zinc oxide，1 phr of accelerator PX，75 ℃ curing temperature，and 1 h curing time. The tensile strength of the vulcanized film of the optimized latex was 28.83 MPa and the tear strength was 65 kN·m-1.Compared with the blank sample without graphene oxide，the tensile strength of the vulcanized film of the optimized latex increased by 45.83%，and the tear strength increased by 51.16%，indicating that graphene oxide had good reinforcing effect on natural rubber.
