摘要
用改性沥青作相容剂,研究溴化丁基橡胶(BIIR)/丁腈橡胶(NBR)并用胶的微观结构和性能。结果表明:与未添加改性沥青CJ-100的BIIR/NBR并用胶相比,添加改性沥青CJ-100的BIIR/NBR并用胶的相容性较好,加工性能改善,气密性、耐屈挠和耐臭氧性能提高;添加5份改性沥青CJ-100的BIIR/NBR(并用比为80/20)并用胶物理性能、气密性、耐屈挠和耐臭氧性能较好,气密性接近全BIIR胶料,有望用于全钢载重子午线轮胎气密层。
The microstructure and properties of brominated butyl rubber（BIIR）/nitrile butadiene rubber（NBR）blend with modified asphalt as compatibilizer were investigated. The results showed that,compared with the BIIR/NBR blend without modified asphalt CJ-100,the BIIR/NBR blends with modified asphalt had better compatibility,processability,air tightness,flexing resistance and ozone resistance. The physical properties,air tightness,flexing resistance and ozone resistance of the BIIR/NBR blend（blending ratio was 80/20）with 5 phr modified asphalt CJ-100 were preferable,and the air tightness was similar to that of all BIIR vulcanizate,which was expected to be applied in the inner liner of all-steel truck and bus radial tire.
