Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a polylactic acid composite material formula and a preparation method thereof. Background technique [0002] At present, with the development of science and technology, all walks of life are also making rapid progress, and the field of polymer materials in the chemical field has also made great progress. Polymer materials are used in various aspects, and various polymer materials are made of The material has good stability, so it is liked by people, but some polymer materials are too stable because of their characteristics, so they will not self-degrade after use. Long-term exposure to the environment will cause greater pollution to the environment. People need a polymer material that can degrade itself. Contents of the invention [0003] In order to overcome the defects of the above-mentioned prior art, the object of the present invention is to provide a polylactic acid compo...
