Study on Recycling ABS Plastic/Nano CaCO3 /TiO2 /POEModified Composites

摘要

The nanocomposites were prepared by adding nano-CaCO3, nano-TiO2 and POE in different proportions to the recycled acrylonitrile butadiene styrene (ABS) plastic. Six different types of recycled ABS plastic modified nanocomposites were prepared. Three mechanical properties of the newly prepared materials were tested, including the tensile strength, impact strength, and flexural strength. The microstructures and physicochemical structures of the composites were further studied by means of scanning electron microscopy (SEM), infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and thermogravimetric-differential thermal analysis (TG-DTA). Through the analysis to determine the best dosage range of toughening agent and filler, the performance of the modified recycled ABS plastic was improved. This also makes the recycled ABS plastic more widely used, which provides a certain value of reference for the recycling of recycled ABS. The results show that the nano-CaCO3, nano-TiO2 and POE are uniformly dispersed in the ABS matrix, the mechanical properties of the ABS plastic are improved, and the thermal decomposition temperature of the modified plastic is increased. It also reveals that the tensile, impact and bending properties of 6.6 % nano-CaCO3, nano-TiO2 composites are improved.
