- Abstract
- The aluminum-titanium compound coupling agent was used for surface organic modification of kaolinite and kaolinite/Ploy (vinyl chloride) (PVC) composites were prepared by molten blending process. The performances of kaolinite and composites were investigated by fourier transform-infraredspectra (FTIR), thermogravimetric analysis (TGA), torque rheometer, environment scanning electron microscope (ESEM) and Ultraviolet visible (UV-vis) absorption spectra. With the FTIR and TGA results, it was confirmed that an organic coating layer was formed on the surface of kaolinite. Torque rheological plots show that the processability of modified kaolinite filled PVC was better than untreated kaolinite system. When filled with 10 wt% modified kaolinite, the comprehensive mechanical performance of PVC has achieved the best. ESEM images showed that modified kaolin can evenly disperse in PVC matrix. TGA and UV-vis spectrum analysis indicated that kaolin can improve thermal stability of PVC composite.
