OF THE DISCLOSURE nThe present disclosure belongs to the technical field of novel biodegradable materials, and nparticularly refers to a method for preparing a biodegradable needle-free airtight infusion connector. nA polylactic acid is used as a raw material, through drying, crystallizing and injection moulding in nsequence, to prepare the biodegradable needle-free airtight infusion connector. The polylactic acid nis an injection molding grade polylactic acid, and has a molecular weight of > 180,000. The product nin the present disclosure has a desirable processability, a high transparency, a high hardness and a ndesirable strength. The product is 100% degraded into carbon dioxide and water within 360 days nafter returning to nature, and thus is environment-friendly and may be used as an upgrading product nof a plastic product, avoiding white pollution.n- 1/1lnFIG. 1 |
