摘　　要：选取二苯醚、氯磺酸、水合肼、氨水为原料,合成4,4-氧代双苯磺酰肼(OBSH)发泡剂。研究溶剂及原料配比、反应温度和反应时间等因素对产物收率的影响,并对以OBSH为发泡剂的EVA发泡材料进行力学性能的测试。在最佳反应条件下,OBSH收率可达87.84%。OBSH发泡剂添加量为8Phr时,EVA发泡材料综合性能最优,其密度为0.155g/cm3,硬度为54.8(Asker C),拉伸强度为3.15 MPa,断裂伸展率为323.0%。The diphenyl ether, chlorsulfonic acid ,ammonia and hydrazine hydrate were used as raw materialto to synthesize the foaming agent of OBSH by a new process.The effects of solvent, feed ratios, temperature and time on yield were studied, and the mechanical property of the EVA foaming by OBSH was tested. The yield of OBSH can be up to 87.84% by the best condition, while the amount of OBSH foaming agent was 8Phr, the comprehensive performance of the EVA foam material was most optimal, density as 0.155g/cm3, hardness as 54.8Asker C,breaking strength as 3.15Mpa, dicumyl peroxide as 323.0%.
