The invention discloses a preparation method of an agricultural automobile butyl inner tube added with butyl rubber powder, and relates to a preparation method of an agricultural automobile inner tube. The formula of the RIIR/IIR/REPDM/capsule reclaimed rubber/butyl rubber powder butyl inner tube comprises the following components in parts by weight: 5-50 parts of RIIR, 35-65 parts of IIR, 7-20 parts of REPDM, 10 parts of capsule reclaimed rubber, 13 parts of 60-mesh butyl rubber powder, 1.1-1.5 parts of sulfur, 2.8-4 parts of an accelerant, 1.5-1.9 parts of a vulcanizing activator, 14-34 parts of carbon black, 1.9-2.0 parts of a plasticizer and 0.32 parts of an anti-aging agent. The butyl inner tube meeting the performance requirements is obtained by adjusting the raw materials and the ratio of the raw materials, the purpose of reducing the cost is achieved by using the regenerated butyl rubber and the butyl rubber powder, and meanwhile rubber products such as the waste butyl inner tube can be recycled. All the properties of the prepared butyl inner tube can reach the national standard.
