| titleOfInvention | Polylactic acid composite material and preparation method thereof |
| abstract | The invention discloses a polylactic acid composite material, and relates to a high polymer materialThe polylactic acid composite material is mainly prepared from the following raw materials in parts by weight: 75-90 parts of polylactic acid, 5-20 parts of elastomer A and 2-15 parts of elastomer B; the elastomer A is a polymer with glycidyl methacrylate groups and has a structural formula Wherein n is more than or equal to 5 1 Less than or equal to 1500; elastomer B is a bio-based polyamide polymer having the formula Wherein n is more than or equal to 5 and less than or equal to 5000, R 1 And R 3 Is an aliphatic main chain structure; r 2 Is a side chain structure with an ester functional group, R 4 Is a main chain structure with thioether. The invention has the beneficial effects that: on the basis of obviously reducing the dosage of the toughening agent, the mechanical properties such as toughness, elongation at break, impact strength and the like of the polylactic acid composition are greatly improved under the condition of less influence on the rigidity and strength of the material. |
