摘要：

为提高废弃含杂纤维的回收率,以废弃的聚对苯二甲酸乙二醇酯基含杂纤维(PET/SrAl₂O₄:Eu²⁺,Dy³⁺)为研究对象,采用乙二醇醇解联合热乙醇的方法,探究含杂纤维的醇解性能并回收发光材料SrAl₂O₄:Eu²⁺,Dy³⁺及PET醇解产物对苯二甲酸双羟乙酯。通过改变乙二醇用量、反应温度及反应时间探讨乙二醇醇解条件对产物性能的影响,借助扫描电子显微镜、X射线衍射仪、差示扫描量热仪、分光光度测色仪、长余辉亮度仪等对醇解产物的微观形貌、物相结构、热稳定性能、余辉性能等进行测试与表征。结果表明:乙二醇用量、反应温度、反应时间和催化剂用量均不会改变发光材料SrAl₂O₄:Eu²⁺,Dy³⁺的物相结构;当反应温度为190 ℃,反应时间为180 min时,含杂纤维的醇解率达到100%,此时SrAl₂O₄:Eu²⁺,Dy³⁺的回收率为93%,初始亮度为3.906 cd/m², 对苯二甲酸双羟乙酯的回收率为82%。

Abstract:

Objective At present, the functional fibers containing various impurities are treated by landfill or incineration, which will not only affect the environment, but also cause the waste of functional materials. Some efforts have been made to recover waste luminescent fibers(polyethylene terephthalate(PET)/SrAl₂O₄:Eu²⁺,Dy³⁺), but the luminescent materials mixed in them are significantly affected by the violent reaction process. How to use a gentle way to complete the reaction and at the same time to ensure the consistency of functional materials is now the problem to be solved.
Method The waste PET/SrAl₂O₄:Eu²⁺,Dy³⁺ was used as the research object through combining ethylene glycol with hot ethanol, in order to recover the luminescent material SrAl₂O₄:Eu²⁺,Dy³⁺ and the alcoholysis product of PET. Different dosage of ethylene glycol were used to study the influence on the reaction temperature and reaction time of products, with the aid of scanning electron microscope, X-ray diffractometer, differential scanning calorimeter instrument, spectrophotometric color measurement instrument, the long afterglow brightness meter to analyze the microscopic morphology, phase structure, thermal stability, persistence, performance testing and characterization.
Results Both reaction temperature and reaction time had significant effects on the rate of alcoholysis and product recovery of PET/SrAl₂O₄:Eu²⁺,Dy³⁺. Under the condition where reaction time was 180 min and the reaction temperature was 190 ℃, the alcoholysis efficiency of PET/SrAl₂O₄:Eu²⁺,Dy³⁺ reached 100% and the recovery rate of the alcoholysis product reached 82%. However, the luminescence of SrAl₂O₄:Eu²⁺,Dy³⁺ was found seriously damaged under the same condition. At 180 ℃ and 180 min, the alcoholysis efficiency of PET/SrAl₂O₄:Eu²⁺,Dy³⁺ was 100%, and the recovery rate of the alcoholysis product was lower than that at 190 ℃, but the luminescence performance of SrAl₂O₄:Eu²⁺,Dy³⁺ was significantly improved. It is also discovered that the appropriate amount of ethylene glycol was able to promote the alcoholysis reaction, and the excessive amount of ethylene glycol can also inhibit the alcoholysis of PET/SrAl₂O₄:Eu²⁺,Dy³⁺. The investigation indicated that ethylene glycol and hot ethanol washing would not change the luminescence performance of the SrAl₂O₄:Eu²⁺,Dy³⁺, and the alcoholysis product was bis-hydroxyethyl terephthalate with high purity. Through the analysis of experimental data, it was found that ethylene glycol combined with hot ethanol is able to reduce the reaction time and reaction temperature required for the alcoholysis reaction, and improves the luminescence performance of the recovered SrAl₂O₄:Eu²⁺,Dy³⁺ and the recovery rate of the alcoholysis products.
Conclusion This research took waste PET/SrAl₂O₄:Eu²⁺,Dy³⁺ as the research object, ethylene glycol, hot ethanol and zinc acetate as raw materials, to optimize the alcoholics process for effective recovery of luminescent materials SrAl₂O₄:Eu²⁺,Dy³⁺ and PET alcoholysis products, and the performance of the recovery products were studied. The results provide a theoretical basis for the green recycling of waste mixed fibers and the recovery of functional materials.
