The invention discloses a seam allowance wear-resistant rubber for a truck radial tire, and belongs to the field of tires. In order to solve the problem of low air tightness of the bead wear-resistant rubber in the prior art, the bead wear-resistant rubber is prepared from the following components: a raw rubber composition, a carbon black composition, stearic acid, zinc oxide, an anti-aging agent composition, protective wax, softening oil, a resin mixture, light magnesium oxide, insoluble sulfur, an accelerant mixture, a scorch retarder CTP and a hardening reinforcing agent. The process is simple and convenient to operate, the components and the process are optimized, so that the air tightness of the seam allowance rubber material is higher, the rubber material, the filler and the chemical material are dispersed more uniformly, the air tightness of the rubber material is improved, and the aging resistance is improved.
本申请公开了一种载重子午线轮胎的子口耐磨胶,属于轮胎领域。针对现有技术中存在的“子口耐磨胶气密性低”的问题,本申请的技术方案中,由以下成分组成:生胶组合物、炭黑组合物、硬脂酸、氧化锌、防老剂组合物、防护蜡、软化油、树脂混合物、轻质氧化镁、不溶性硫磺、促进剂混合物、防焦剂CTP,增硬补强剂。本发明工艺简单和操作方便,本发明通过对组分和工艺进行优化,使得子口胶料的气密性更高,并使得胶料、填料、化学材料分散更加均匀,进而改善胶料气密性,提高耐老化性。
