摘要

邻苯二甲酸酯类增塑剂由于迁移性差和对人体的潜在危害，在世界范围内的应用受到限制。因此，利用清洁、可重复利用的资源生产功能性生物基增塑剂是满足当前需求的。本研究通过环氧化反应和开环加成反应制备了阻燃橡胶籽油基增塑剂(FRP)，作为聚氯乙烯阻燃增塑剂替代石油基邻苯二甲酸酯增塑剂。当用FRP代替DOP时，PVC共混物的扭矩从11.4 N·m增加到18.4 N·m, LOI值从PVC-FRP-0%的24.3%增加到PVC-FRP-20的33.1%。THR值从39 MJ/m(属于PVC- frc -0)下降到22 MJ/m, Tg从23°C增加到47°C，浸出试验中塑化PVC共混物的失重率从22.6%显著降低到2.8%。为以橡胶籽油为原料制备阻燃增塑剂提供了一条新途径。

Phosphorus Containing Rubber Seed oil as a Flame Retardant Plasticizer for Polyvinyl Chloride

The application of phthalate plasticizers has been restricted around the world due to their poor migration and potential harm to the human body. Hence, producing functional bio-based plasticizers via exploiting clean and reusable resources meets the satisfaction of current demands. In this study, flame-retardant rubber seed oil-based plasticize (FRP) was prepared via epoxidation reaction and ring opening addition reactions, which was used as a flame-resistant plasticizer for polyvinyl chloride to replace petroleum-based phthalate plasticizer. When DOP was replaced with FRP, the torque of PVC blends increased from 11.4 to 18.4 N⋅m, the LOI value increased from 24.3% for PVC-FRP-0% to 33.1% for PVC-FRP-20. The THR value diminished from 39 MJ/m (pertaining to PVC-FRC-0) to 22 MJ/m Tg increased from 23°C to 47°C, the weight loss of plasticized PVC blends significantly reduced from 22.6% to 2.8% in leaching tests. The study provided a new way to prepare flame retardant plasticizer using rubber seed oil as raw material.

期刊介绍： This journal publishes high quality peer reviewed original research and review articles on macromolecules and additives obtained from renewable/biobased resources. Utilizing a multidisciplinary approach, JRM introduces cutting-edge research on biobased monomers, polymers, additives (both organic and inorganic), their blends and composites. JRM showcases both fundamental aspects and applications of renewable materials. The fundamental topics include the synthesis and polymerization of biobased monomers and macromonomers, the chemical modification of natural polymers, as well as the characterization, structure-property relationships, processing, recycling, bio and environmental degradation and life cycle analysis of the ensuing materials, in view of their potential applications. Within this sustainability approach, green chemistry processes and studies falling within biorefinery contexts are strongly favored.
