The invention discloses a lorry inner tube raw material added with regenerated butyl rubber, and relates to an automobile inner tube raw material. The formula of the RIIR/IIR/REPDM/capsule reclaimed rubber butyl inner tube comprises the following components in parts by weight: 20-60 parts of RIIR, 30-55 parts of IIR, 3-14 parts of REPDM, 10 parts of capsule reclaimed rubber, 1.0-2.0 parts of sulfur, 1.4-2.0 parts of an accelerant, 2.5-4.0 parts of a vulcanizing activator, 10-30 parts of carbon black, 1-8 parts of a plasticizer and 0.32 parts of an anti-aging agent. The butyl inner tube meetingthe performance requirements is obtained by optimizing the proportion of the raw materials, the purpose of reducing the cost is achieved by using the regenerated butyl rubber, and meanwhile, the rubber product has the excellent performance of each matrix rubber; and the reclaimed rubber is an available resource and can be recycled, the rubber products such as waste butyl inner tubes and the likeare recycled, and various properties of the prepared inner tubes meet the national standard.
