Abstract

A technique for obtaining an unsaturated polyester resin based on recycled polyethylene terephthalate has been developed. The process of curing an unsaturated polyester resin under the action of styrene, a peroxide compound (Butanox 50M) and an accelerator (cobalt ortoate) has been studied. The physical and mechanical properties of polymeric materials based on the developed resin have been studied, it was found that their strength depends on the mass fraction of recycled polyethylene terephthalate in the oligoether polyol used in the synthesis.
利用回收的聚对苯二甲酸乙二酯溶解产物获得不饱和聚酯树脂
我们开发了一种以回收聚对苯二甲酸乙二酯为基础获得不饱和聚酯树脂的技术。研究了不饱和聚酯树脂在苯乙烯、过氧化物化合物(Butanox 50M)和促进剂(邻苯二甲酸钴)作用下的固化过程。对以开发的树脂为基础的聚合材料的物理和机械性能进行了研究,发现其强度取决于合成中使用的低聚醚多元醇中回收聚对苯二甲酸乙二醇酯的质量分数。
