以地沟油为主要原料,经过甘油多元醇醇解后,再与聚酯饮料瓶的有效成分聚对苯二甲酸乙二酯酯化,合成了一种性能优异的改性醇酸树脂胶黏剂,并探讨了地沟油、甘油和聚酯之间的质量比及反应温度对合成的醇酸树脂胶黏剂性能的影响。研究结果表明,地沟油:甘油:聚酯的质量比为1:0.26:1.44,地沟油和甘油在220℃下进行醇解,然后加入聚酯在240℃下进行酯化反应,在此条件下合成的醇酸树脂油度为37%,涂膜后胶带的初粘力、持粘力和剥离强度均得到改善。
The waste oil as the main raw material, after alcoholysis of glycerol polyol, and then with the polyester beverage bottle poly ethylene terephthalate esterification, synthesis of an excellent performance modified alkyd resin adhesive The effects of the ratio of waste oil, glycerol and polyester, and the reaction temperature on the properties of the synthetic alkyd adhesive were also discussed. The results showed that the ratio of waste oil to glycerol to polyester was 1: 0.26: 1.44, the waste oil and glycerol were alcoholysis at 220 ℃, and then the polyester was esterified at 240 ℃. Under these conditions The alkyd resin was synthesized at 37% oil, and the initial tack, tack and peel strength of the tape were improved.
