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.
