Problems solved by technology

[0002] The inner tube is an important part of the tire. The special carbon black reinforcing agent for the traditional inner tube formula is expensive, and the mixing and extrusion process generates a lot of heat. The self-adhesiveness of the rubber is poor, which affects the bonding strength of the inner tube joint and the valve. Engineering inner tubes have problems such as heavy weight and high cost, and the main reason for these problems is the limitation of production technology and raw materials; in recent years, with the emergence of new varieties of raw materials, it has created the possibility for the improvement of the processability and physical and mechanical properties of the rubber compound. Therefore, what kind of nanomaterials to use and how to apply nanomaterials to improve the manufacturability and physical and mechanical properties of the rubber compound, reduce material costs, and reduce the weight of the inner tube are technical problems that need to be solved by those skilled in the art
