Problems solved by technology

[0002] Polylactic acid, also known as polylactide, is a polyester polymer obtained by polymerization of lactic acid as the main raw material. It is a new type of biodegradable material; traditional polylactic acid resins have poor high temperature resistance after modification, and are easily decomposed. The low strength leads to a narrow range of use of polylactic acid resin materials. At the same time, the production process of polylactic acid resin and its modified production process is troublesome, time-consuming and laborious; and the traditional polylactic acid resin and its modified production process are expensive raw materials and troublesome processing, which increases production. Cost is not conducive to processing and production; in view of these defects, it is necessary to design a high temperature resistant polylactic acid resin and its modified production process
