摘要: 本文将合成目标产物环氧松香基增塑剂：氢化松香缩水甘油酯，丙烯海松酸二缩水甘油酯，富马海松酸三缩水甘油酯。环氧松香基增塑剂分别与邻苯二甲酸二辛酯(DOP)复配使用增塑聚氯乙烯(PVC)。采用红外光谱对环氧松香基增塑剂进行了结构表征，采用扫描电子显微镜(SEM)，X射线衍射(XRD)对改性PVC结构表征，采用万能试验机、差示扫描量热仪、接触角、溶剂试验对改性PVC性能表征。结果表明，合成了目标产物环氧松香基增塑剂，其对PVC有良好的增塑效果。改性PVC维持良好的应用热稳定性和亲水性，其机械力学性得到了较大的提升，其中R2的拉伸强度分别为27 MPa；相对的断裂伸长率为164%。并具有良好的耐酸碱溶液的迁移性。因此，环氧松香基增塑剂可作为一种良好的生物基增塑剂。
Abstract: In this paper, the target products of epoxy rosin-based plasticizer: hydrogenated rosin glycidyl ester, propylene pimaric acid diglycidyl ester, triglycidyl fumarate and dioctyl phthalate (DOP) were mixed with plasticized polyvinyl chloride (PVC) respectively. The structure of epoxy rosin-based plasticizer was characterized by infrared spectroscopy. The structure of modified PVC was characterized by scanning electron microscope (SEM), X-ray diffraction (XRD). The properties of modified PVC were characterized by universal testing machine, differential scanning calorimeter, contact angle and solvent test. The results showed that the target product epoxy rosin-based plasticizer was synthesized and it had good plasticizing effect on PVC. The modified PVC maintained good thermal stability and hydrophilicity, and its mechanical properties were greatly improved, in which the tensile strength of R2 was 27 MPa, the relative elongation at break was 164%, and it was resistant to the migration of acid and alkali solution. Therefore, epoxy rosin-based plasticizer can be used as a good bio-based plasticizer.
