摘要
Abstract
Two bio-based plasticizers,methyl acetyl oleate-salicylate(A-MO-SAE)and butyl acetyl oleate-salicylate(A-NBO-SAE),were synthesized from methyl oleate and butyl oleate through a three-step process involving epoxidation,reaction with salicylic acid,and acetylation with acetic anhydride.Their performance was compared with a commercial al-ternative,cyclohexane-1,2-dicarboxylic acid diisononyl ester(DINCH).The chemical structures of the synthesized plas-ticizers were confirmed by FTIR and NMR spectroscopy.The properties of plasticized PVC were evaluated through ten-sile tests and migration resistance measurements.Results demonstrated that A-MO-SAE,with its shorter alkyl chain,exhibited a superior plasticizing effect.The PVC film plasticized with A-MO-SAE showed enhanced thermal stability,with a 50%weight loss temperature(Td-50%)of 326 ℃,23 ℃ higher than that of DINCH.This film also exhibited a tensile strength of 35.2 MPa,an elongation at break of 462.9%,and a light transmittance of 92%.Furthermore,A-MO-SAE demonstrated lower volatility and better resistance to solvent extraction than DINCH.In conclusion,A-MO-SAE is a promising eco-friendly plasticizer with excellent comprehensive properties,capable of significantly enhancing the performance of PVC materials.关键词
