【摘要】 通过在乳液聚氯乙烯(PVC)中添加有机蒙脱土(OMMT)来研究OMMT对其各项性能的影响。结果表明:OMMT对乳液PVC/邻苯二甲酸二辛酯(DOP)/OMMT纳米复合材料的力学性能有一定的改善效果;对复合材料的抗增塑剂迁移效果明显;在耐酸和耐碱试验中,未添加OMMT的复合材料的拉伸强度和撕裂强度分别降低了7.3%、5.1%和5.5%、13.3%,而添加3份OMMT后,仅仅降低了2.5%、2.6%和1.5%、4.2%,效果显著。更多还原

【Abstract】 The effects of OMMT on the various properties of emulsion PVC were studied by the adding of OMMT to the emulsion PVC.The result shows that OMMT has a certain improvement effect on the mechanical properties of the emulsion PVC/DOP/OMMT nano-composites;and a significant effect on the anti-migration of plasticizer in the nano-composites;In the experiments of acid and alkali resistance,without adding OMMT,the tensile strength and tear strength of the nano-composites had dropped by 7.3%,5.1%and 5.5%,13.3%respectively; but there was a significant effect after adding 3 parts of OMMT,the tensile strength had dropped by only 2.5%,2.6%and the tear strength 1.5%,4.2%had dropped respectively.更多还原
