Description

technical field [0001] The invention relates to the technical field of rubber, in particular to modified graphene rubber and a preparation method thereof. Background technique [0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. The molecular chains of the rubber can be cross-linked. When the cross-linked rubber is deformed by an external force, it has the ability to recover quickly, and has better physical and mechanical properties and chemical stability. Rubber is the basic raw material of the rubber industry and is widely used in the manufacture of tires, hoses, tapes, cables and other rubber products. Traditional rubber products are not weather-resistant, not durable, have low friction resistance, are easy to crack, and have poor tensile strength, which makes rubber products ...
