使用可再生资源环氧豆油与三氯氧磷合成了豆油基磷–氯协同阻燃增塑剂。使用傅里叶变换红外光谱和核磁共振氢谱对合成产品的结构进行了分析和表征,结果表明得到了预期的产品。将该产品与聚氯乙烯(PVC)热塑共混成型制备了阻燃增塑PVC共混体系,使用热重分析仪、马弗炉、极限氧指数(LOI)仪和万能拉力试验机对阻燃增塑PVC共混体系的热稳定性能、阻燃性能及力学性能进行了表征。结果表明,合成的大豆油基磷–氯协同阻燃增塑剂对PVC具有高效的阻燃和增塑作用,当其用量从0份增加到30份时,阻燃增塑PVC共混体系的LOI从24.1%增加到33.2%,断裂伸长率从170.14%增加到260.32%,热稳定性也得到提高;合成的阻燃增塑剂的阻燃机理主要是通过促进PVC共混体系表面形成致密的炭层来阻止共混体系进一步热降解。

Flame retardant plasticizer based on soybean oil containing P and Cl was synthesized through reacting renewable resource epoxy soybean oil with phosphorus oxychloride. The synthetic product was characterized with FTIR and 1H–NMR,the characterization results indicate that the flame retardant plasticizer is synthesized successfully. The flame retardant plasticizer was melted with polyvinyl chloride (PVC) for preparing fame-retardant plasticized PVC blend systems. The thermal,flame-retardant and mechanical properties of the blend systems were studied by TG tester,muffle,limited oxygen index (LOI) tester and universal tensile testing machine. The results show that the flame retardant plasticizer has excellent flame retardant and plasticization effect on the blend systems. When the content of the flame retardant plasticizer increases from 0 phr to 30 phr,the LOI of the blend systems increases from 24.1%to 33.2%and the elongation at break increases from 170.14%to 260.32%,the thermal stability also is improved. The flame-retardant mechanism of the flame retardant plasticizer is that it can form a compact isolation carbon layer on the surface of the blend system in burning process for preventing the further thermal decomposition of the system.
