摘要
研究乙酰环氧化植物油酸甘油酯(HM-828)和环氧大豆油(HM-107)及其复配增塑对PVC的拉伸性能、塑化效果、微观形态结构和析出性能的影响。HM-107增塑PVC效果不佳,断裂较平整,存放90天后增塑剂严重析出。HM-828增塑PVC时混炼5min时不能充分塑化,15min可获得良好的塑化效果,断裂伸长率从250. 9%提高到279. 9%,断面粗糙呈鱼鳞状,出现韧性断裂特征; HM-828增塑配方中添加0. 5%的ACR可产生协同效应,在充分塑化条件下可获得更均匀的微观结构,拉伸强度和断裂伸长率进一步提高。HM-828对PVC的增塑和增韧的效果均优于HM-107,断裂伸长率相对较高,长时间存放无析出。
The effects of acetyl epoxidation of glycerol oleate（ HM-828） and epoxy soybean oil（ HM-107） and its composite plasticized PVC on the tensile properties,plasticizing effect,microstructure and precipitation properties of PVC were studied. PVC plasticized by HM-107 was not good,the fracture was relatively smooth,and the plasticizer is precipitated after 90 days. PVC plasticized by HM-828 could not be fully plasticized when mixed for 5 minutes. Good plasticizing effect could be obtained in 15 minutes. The elongation at break increased from 250. 9 % to 279. 9 %. The rough section was characterized with of ductile fracture occur. The addition of 0. 5 % ACR to the HM-828 plasticizing formulation produced a synergistic effect. A more uniform microstructure could be obtained under sufficient plasticization conditions,and the tensile strength and elongation at break could be further increased. The plasticizing and toughening effects of PVC with HM-828 was superior to HM-107,which was characterized with relatively high elongation at break and no precipitation during long-term storage.
