摘　　要：将热塑性聚醚酯弹性体(TPEE)和丙烯酸酯橡胶(ACM)共混动态硫化制成一种耐油、耐热的热塑性硫化胶(TPEE/ACM TPVs),并在制备TPEE/ACM TPVs的过程中添加不同量的纳米SiO2,研究了TPEE/ACM共混比和纳米SiO2对TPEE/ACM TPVs动态力学性能、流变性能、力学性能、热稳定性能、耐热老化性能和耐热油性能的影响.研究结果表明:当TPEE/ACM共混比为60/40时,TPVs的综合性能较好;纳米SiO2使TPVs的加工性能变差;TPVs只有一个玻璃化转变温度,纳米SiO2提高了TPVs的玻璃化转变温度;当纳米SiO2添加量为20%(质量分数)时,TPVs的综合力学性能较好;当纳米SiO2添加量为10%或20%时,TPVs的耐热老化性能和耐热油性能较好.By using thermoplastic polyeher ester elastomer （TPEE） and acrylate rubber （ACM） as the raw materials, thermoplastic vulcanizate composites with oil and thermal resistance, namely TPEE/ACM TPVs, were prepared via a dynamic vulcanization at different nano-SiO2 dosages. Then, the dynamic mechanical property, the rheological behavior, the thermal stability, the heat-aging property and the heat oil resistance of the product were investigated at different TPEE/ACM ratios and nano-SiO2 dosages. The results show that TPEE/ACM TPVs with high per- formance can be produced when the TPEE/ACM ratio achieves 60/40, that the processability of TPVs becomes poor with the addition of nano-SiO2 , that TPVs has only one glass transition temperature that increases after the addition of nano-SiO2, that the TPVs with a nano-SiO2 dosage of 20% （ mass fraction） is of high performance, and that better heat-aging property and strong heat oil resistance may obtained when the nano-SiO2 dosage varies from 10% to 20%.
