【摘要】 采用环保型废橡胶复原机制备丁基再生橡胶（R-IIR）,研究R-IIR的基本性能及其与溴化丁基橡胶（BIIR）并用在轮胎气密层中的应用。结果表明:R-IIR的各项性能均达到国家标准要求;以5～25份R-IIR与BIIR并用,随着R-IIR并用量的增大,胶料的粘辊性改善,加工性能提高,F_L相差不大,F_max先减小后增大,t₁₀和t₉₀总体延长;硫化胶的拉伸性能略有下降,撕裂强度变化不大,耐热氧老化性能和气密性保持良好。更多还原

【Abstract】 The reclaimed butyl rubber（R-IIR） was prepared by environmental-friendly waste rubber recovery process,and the basic properties of R-IIR and its application in the inner liner of tire with brominated butyl rubber（BIIR） was studied. The results showed that,the properties of R-IIR met the requirements of national standards. When 5 ～ 25 phr of R-IIR were blended with BIIR,with the dosage of R-IIR increased,the roller adhesion and processability of the compound were improved,the F_L was similar,the F_max was decreased at first and then increased,the t₁₀ and t₉₀ were overall extended. The tensile properties of the vulcanizate decreased slightly with the addition of R-IIR,the tear strength changed little,and the thermo-oxidative aging resistance and air tightness remained good.更多还原
