The invention discloses anti-revulcanization support rubber for run-flat tires, and relates to the technical field of rubber production. The anti-revulcanization supporting rubber for a run-flat tireis prepared from the following raw materials in parts by weight: 3# smoked sheet rubber, neodymium butadiene rubber, carbon black N550, TDAE oil, poly-2,2,4-trimethyl-1,2-dihydroquinoline, N-(1,3-dimethyl)butyl-N'-phenyl p-phenylenediamine, zinc oxide, stearic acid, sulfenamide accelerators, sulfur, scorch retarder and anti-revulcanization additives. The supporting rubber has good vulcanization revulcanization resistance, and meanwhile, the resilience, flexibility, tearing strength, low heat generation and other properties of vulcanized rubber can still be well maintained.

    本发明公开了一种用于缺气保用轮胎的抗硫化返原的支撑胶,涉及橡胶生产的技术领域。一种用于缺气保用轮胎的抗硫化返原的支撑胶,由下述原料按重量份配比组成:3#烟片橡胶、钕系顺丁橡胶、炭黑N550、TDAE油、聚‑2,2,4‑三甲基‑1,2‑二氢喹啉、N‑(1,3‑二甲基)丁基‑N'‑苯基对苯二胺、氧化锌、硬脂酸、次磺酰胺类促进剂、硫黄、防焦剂、抗硫化返原助剂。该支撑胶不仅具有良好的耐硫化返原性,同时硫化胶的回弹性、曲挠性和抗撕裂强度及生热低等性能仍可以较好的保持。
