Synthesisand shown in Figure 5, the blends compared with pure PLA, the melting point there is only one, and almost Zhu change, indicating that MMT and PLA polyurethane and composite material obtained has good compatibility. Shown in Figure 6, the blends compared with pure PLA, TG are slightly lower, indicating that composite materials compared with pure PLA, thermal stability is appropriate. 3 Conclusion solution blending method using polyurethane and polylactic acid montmorillonite was modified by the experimental data, the following conclusions: (1) through the mechanical properties showed that the composite rate and fracture Zhong Chang Chung-strength tensile were improved, and gradually change from brittle to ductile. (2), confirmed by infrared spectroscopy, polyurethane, montmorillonite and the formation of blend membranes of polylactic acid can be blended to achieve a better effect, has good compatibility. (3) Analysis of thermal properties, composite materials after blending, melting point and stability, weight loss slightly decreased, indicating that the compatibility of composite materials, good thermal stability. Finally, add the urethane and montmorillonite, while improving the polylactic acid can reduce the cost of composite materials, so that the PLA to be more widely used.
