摘要
研究了传统硫化(CV)体系、半有效硫化(SEV)体系、有效硫化(EV)体系、过氧化物双叔丁基过氧异丙基苯(BIBP)/三烯丙基异氰脲酸酯(TAIC)硫化体系和酚醛树脂SP1045硫化体系对生物基衣康酸酯橡胶性能的影响。结果表明,BIBP/TAIC硫化体系硫化速率最快,而SP1045硫化体系硫化速率最慢,CV体系、SEV体系和EV体系硫化速率依次逐渐加快;硫黄硫化体系硫化胶的交联密度由大到小依次为:CV体系、SEV体系和EV体系;硫化胶拉伸强度由大到小依次为:SEV体系、SP1045硫化体系、CV体系、EV体系和BIBP/TAIC硫化体系,其中EV体系硫化胶的扯断伸长率和撕裂强度最大,CV体系硫化胶的耐磨性能最好;BIBP/TAIC硫化体系硫化胶具有最优的耐热氧老化性能;与硫黄硫化体系相比,BIBP/TAIC和SP1045硫化体系硫化胶玻璃化转变温度明显向高温方向偏移;CV体系硫化胶60℃时的损耗因子和滚动阻力均为最小;EV体系硫化胶的的有效阻尼温域最宽。
The effects of conventional vulcanization(CV)system,semi-effective vulcanization(SEV)system,effective vulcanization(EV)system,peroxide 1,3-bis(tert-butylperoxyisopropyl)benzene(BIBP)/triallyl isocyanurate(TAIC)vulcanization system,and phenolic resin SP 1045 vulcanization system on properties of poly(di-n-butyl itaconate-co-butadiene)rubber were studied.The results showed that the vulcanization rate of BIBP/TAIC vulcanization system was the fastest,while the vulcanization rate of SP 1045 vulcanization system was the slowest,and the vulcanization rate of CV system,SEV system,and EV system increased gradually in sequence.The crosslinking densities of the vulcanizates of the sulfur vulcanization systems in descending order were CV system,SEV system and EV system.Tensile strength of all the vulcanizates in descending order were SEV system,SP 1045 vulcanization system,CV system,EV system and BIBP/TAIC vulcanization system,in which elongation at break and tear strength of the vulcanizate of EV system were the largest,and the wear resistance of the vulcanizate of CV system was the best.The vulcanizate of BIBP/TAIC vulcanization system had the best thermal-oxydative aging property.Compared with the sulfur vulcanization systems,the glass transition temperatures of the vulcanizates of BIBP/TAIC and SP 1045 vulcanization systems shifted significantly towards to the high-temperature direction.The loss factor at 60℃and rolling resistance of the vulcanizate of CV system were both the smallest.The effective damping temperature range of the vulcanizate of EV system was the widest.
