摘要： 邻苯二甲酸类增塑剂是聚氯乙烯中添加量最多的助剂,但研究发现,这种单体型增塑剂耐迁移性能差,具有潜在的致癌性,严重影响产品的应用性能和使用寿命,环保安全的高效增塑剂成为目前的研发热点。将环保增塑剂聚己二酸丙二醇酯(PPA)和环氧大豆油(ESO)与邻苯二甲酸二辛酯(DOP)进行了一定比例的复配,通过考察力学性能、增塑效率、热性能和耐久性能,探讨了复配增塑剂的增塑性能。结果表明,40DOP/10PPA、40DOP/ 10ESO 增塑PVC的效果较好,增塑效率均达到110%以上,其耐抽出、耐挥发性能远远优于DOP,且能极大地降低 PVC的玻璃化转变温度,提高PVC的价格性能。

Abstract: Phthalate-based plasticizers are the most added additives in polyvinyl chloride, however, it was found that the monomer-type plasticizer had poor migration resistance and potential carcinogenicity, which seriously affected the application performance and service life of the product. Polypropylene glycol adipate (PPA), epoxy soybean oil (ESO) and dioctyl phthalate (DOP) were compounded in this paper. The mechanical properties, plasticizing efficiency, thermal properties and durability of the plasticizer were investigated. The results show that the plasticizing efficiency of 40DOP/10PPA and 40DOP/10ESO is better than 110%, the performance of anti-extraction and anti-volatilization is much better than DOP, which can greatly reduce the glass transition temperature of PVC and improve its processing performance of PVC.

Key words: Plasticizer, DOP, Epoxidized soybean oil, Propylene adipate, Compound
