The invention belongs to the technical field of biodegradable polylactic acid materials, and particularly relates to medical PLA goggles and a preparation method thereof. The medical PLA goggles are made of polylactic acid and an antifogging agent, wherein the mass ratio of the polylactic acid to the antifogging agent is 90-98: 2-10. The invention adopts a 260t injection molding machine and produces the medical goggles by an injection-drawing production process, and the prepared medical goggles have good antifogging property, good transparency and long antifogging time, can be effectively recycled after being used, can be degraded into carbon dioxide and water by 100 percent within 500 days, have no residues, and are green and environment-friendly. |
