Embodiment Construction
[0038] Please refer to Fig. 1, which is a schematic diagram of the manufacturing process of a polylactic acid plant fiber composite decomposable material according to the present invention. into, its manufacture method is as follows:
[0039] a. The high-molecular starch polylactic acid 11 is catalyzed by the catalyst 12 at high speed and high temperature, so that its molecular weight is changed into plasticity, and the polylactic acid masterbatch 10 can be stretched in four directions;
[0040] b. Use agricultural waste (such as corn stalks, cotton stalks, millet stalks) or waste left over from agricultural processing (such as rice husks, cassava flour), and grind them into the required particle size and mesh at a high speed by cooling the physical principle Plant fiber powder 21, then carry out high-temperature sterilization and emulsification polymerization with starch 22 to make plant fiber filler 20;
[0041] c. mix and mix polylactic acid masterbatch 10, plant fiber fil...
