Abstract

Polyvinyl chloride (PVC) is among the top three most widely used plastics globally. Di(2-ethylhexyl) phthalate (DEHP) is often added as a plasticizer by up to 40 wt% to impart flexibility. DEHP, a toxin and carcinogen, can leach into the atmosphere to cause environmental contamination. This study investigates the suitability of epoxidized safflower oil, namely Carthamus tinctorius oil (ECTO), as a PVC plasticizer. PVC films with DEHP and ECTO were compared in resilience, elastic modulus, toughness, and glass transition temperature. ECTO films displayed statistically similar physical properties of resilience, elastic modulus, and toughness at up to 30 wt%. ECTO films of 0 to 40 wt% all displayed significantly lower glass transition temperature.

环氧化红花油对聚氯乙烯薄膜性能的影响

聚氯乙烯(PVC)是全球使用最广泛的三大塑料之一。邻苯二甲酸二(2-乙基己基)酯(DEHP)通常作为增塑剂添加高达40 wt%，以赋予灵活性。DEHP是一种毒素和致癌物，可以渗入大气中造成环境污染。研究了环氧化红花油(Carthamus tinctorius oil, ECTO)作为PVC增塑剂的适用性。比较了DEHP和ECTO的PVC膜的回弹性、弹性模量、韧性和玻璃化转变温度。在高达30% wt%的情况下，ECTO薄膜在弹性、弹性模量和韧性方面表现出统计学上相似的物理特性。0 ~ 40wt %的ECTO薄膜都显示出明显较低的玻璃化转变温度。

期刊介绍： The Journal of Elastomers and Plastics is a high quality peer-reviewed journal which publishes original research on the development and marketing of elastomers and plastics and the area in between where the characteristics of both extremes are apparent. The journal covers: advances in chemistry, processing, properties and applications; new information on thermoplastic elastomers, reinforced elastomers, natural rubbers, blends and alloys, and fillers and additives.
