Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a conductive nano-rubber material and a preparation method thereof. Background technique [0002] Neoprene is manufactured from latex, and some of the non-rubber components contained in the latex remain in the solid neoprene. Generally, neoprene rubber contains 92%-95% rubber hydrocarbons, while non-rubber hydrocarbons account for 5%-8%. Due to different production methods, different production areas and even different rubber harvesting seasons, the proportions of these ingredients may vary, but they are basically within the range. [0003] In recent years, the rubber industry has developed a lot. The existing sub-sectors have grown steadily, while the new rubber sub-sectors have developed rapidly. However, at the same time, the rubber industry still has problems such as the environment, resources, disasters, and innovation. [0004] In 2004, the total planting area of...
