【摘要】 以软质聚氯乙烯(PVC)为主体材料,加入发泡剂偶氮二碳酰胺(AC)、交联剂过氧化二异丙苯(DCP)、柠朦酸、丁腈橡胶(NBR)、泡孔调节剂等,采用一步法模压成型软质PVC鞋底发泡材料。研究AC,DCP,柠朦酸、NBR、泡孔调节剂用量对软质PVC发泡材料密度和力学性能的影响。结果表明,在AC 4．0份、DCP 0．2份、柠朦酸0．2份、NBR 40．0份、泡孔调节剂11.0份时,发泡材料性能优异,其密度和力学性能满足软质PVC鞋底发泡材料的要求。更多还原

【Abstract】 On the base of soft polyvinyl chloride (PVC), blowing agents azodicarbamide (AC), cross-linking agents dicumyl peroxide (DCP), citric acid, nitrile-butadiene rubber (NBR) and processing agents were added, and soft PVC foamed sole materials were made by the one-step compression moulding. The influences of the contents of AC, DCP, citric acid, NBR and processing agents on the density and mechanical properties of soft PVC foamed materials are discussed . The results show that when AC, DCP, citric acid, NBR and processing agents are added 4. 0, 0. 2, 0. 2, 40. 0, 11. 0 (mass ratio) respectively the properties of foamed materials are good, and density and mechanical properies of foamed materials fulfil the demands of soft PVC foamed sole materials.更多还原
