温度对食品级PVC中4种增塑剂迁移量的影响

The Temperature Impact on Migration of Four Kinds of Plasticizer in Food Packaging PVC Materials

以食品包装材料聚氯乙烯(PVC)为研究对象,研究PVC中邻苯二甲酸二乙酯(DEP)、邻苯二甲酸二异丁酯(DIBP)、邻苯二甲酸二丁酯(DBP)、邻苯二甲酸二(2-乙基)己酯(DEHP)4种增塑剂在30℃～80℃条件下,水、乙酸、乙醇、正己烷4种模拟液中的迁移情况。结果表明,此4种增塑剂都在正己烷的环境下迁移量最大,并且在各种食品模拟液中的迁移量均随温度的升高而增大。

Study on the determination and migration of four kinds of plasticizer （DEP, DIBP, DBP, DEHP） from four kinds of simulation relocation of water, acetic acid, ethanol, n-hexane at 30℃-80 ℃. The result showed that the largest migration of the four kinds of plasticizer were in the context of n-hexane, and as the temperature increase, migration increase in all of the simulated fluid.
