Preparation method of shock-resistant and deformation-resistant modified polylactic acid material

Through mixing extrusion of 70-80% of polylactic acid with the molecular weight of 20000-200000, 10-20% of a plasticizer, 5-10% of a toughening agent, 0.5-1% of an antioxidant and 0.5% of a coupling agent, the material toughness and plasticity are greatly improved, and a shock-resistant and deformat...
