| titleOfInvention | High-strength and high-toughness polylactic acid alloy and preparation method thereof |
| abstract | The high-strength and high-toughness polylactic acid alloy disclosed in the present invention is made of polylactic acid and a flexible copolyester containing rigid cyclic groups through a melting reaction under the action of an interface compatibilizer, and the tensile strength of the material is 50.6-79.0MPa , the elongation at break is 50.0‑298.4%, and the notched impact strength is 48.0‑578.0J/m. The invention also discloses its preparation method. Since the present invention adds an interface compatibilizer while introducing a flexible copolyester containing a rigid cyclic group, it can not only hinder the free rotation and movement of the segment, but also effectively improve the interphase between the polylactic acid and the copolyester. The interfacial compatibility of PLA-based materials can induce stress transfer and dissipate energy, which can effectively maintain its mechanical strength while significantly improving the toughness of PLA-based materials. And the preparation method is simple and mature, easy to control, high yield, and has good social and economic benefits. |
