The invention belongs to the technical field of inner tubes, and particularly relates to a formula of a butyl reclaimed rubber and natural reclaimed rubber combined high-cut-resistance modified Uyou butane inner tube. The raw materials comprise the following components in parts by weight: 50-70 parts of brominated butyl regenerated rubber, 150-30 parts of butadiene styrene rubber 150220, 30-50 parts of natural rubber 3L, 5-15 parts of fine natural regenerated rubber, 30-45 parts of high-reinforcing carbon black, 6-12 parts of a gas barrier agent, 8-15 parts of operating oil, 2-5 parts of tackifying resin, 5-8 parts of an active system, 2.5-4.5 parts of a protective system and 1-3 parts of protective wax; according to the invention, the situation that the existing inner tube is easily cut by sharp foreign matters and is scrapped can be improved, the processability is improved, the cost investment can be reduced to a certain extent, and in addition, the air tightness of the inner tube can be greatly improved.

    本发明公开的属于内胎技术领域,具体为一种丁基再生胶与天然再生胶并用的高耐割改性优丁内胎配方,包括原料,所述原料按份量计包括:溴化丁基再生橡胶50份‑70份、丁苯橡胶150220份‑30份、天然橡胶3L 30份‑50份、精细天然再生橡胶5份‑15份、高补强炭黑30份‑45份、气体阻隔剂6份‑12份、操作油8份‑15份、增粘树脂2份‑5份、活性体系5份‑8份、防护体系2.5份‑4.5份、防护蜡1份‑3份、加工助剂1份‑3份、硫磺1份‑2.5份、促进体系1份‑2.5份,本发明具有能够改善现有的内胎容易被尖锐异物割破而发生报废的情况,提高了加工性能,并能够在一定程度上降低成本的投入,此外,还能够极大提高内胎的气密性。
