Summary: | The invention relates to the technical field of polylactic acid modification, and discloses a transparent heat-resistant fully-degradable component polylactic acid composite material and a preparation method thereof. The composite material comprises polylactic acid and nucleating masterbatch; the nucleating masterbatch comprises high-molecular-weight polylactic acid and a beta-nucleating agent; the composite material comprises the following components in parts by weight: 100 parts of polylactic acid, 3-15 parts of high-molecular-weight polylactic acid and 1-10 parts of the beta-nucleating agent. The invention also discloses a preparation method of the composite material. According to the polylactic acid composite material, the adopted process is simple and easy to operate, and after the transparency-heat resistance is optimized, the polylactic acid composite material can be widely applied to high-performance PLA-based composite materials and manufacturing of important industrial products including medical mat |
