Beschreibung
Zusammenfassung:	The invention discloses a method for preparing a transparent toughened polylactic acid material based on silicone rubber microspheres, which is characterized by comprising the following steps: S1, carrying out cohydrolytic polycondensation on dimethyl dichlorosilane and alkyl phenyl dichlorosilane to obtain hydroxyl-terminated polydimethyl alkyl phenyl siloxane with the polymerization degree of 8-14; S2, uniformly mixing a silane cross-linking agent containing three or more alkoxy groups with hydroxyl-terminated polydimethyl alkyl phenyl siloxane, then keeping the temperature of the mixture at -5 DEG C to 3 DEG C, and adding a catalyst and an emulsifier under the temperature condition to obtain an emulsion; S3, placing the emulsion at the temperature of 20-30 DEG C for 22-30 hours for vulcanization, and then sequentially carrying out demulsification, filtration, water washing and drying to obtain silicone rubber microspheres; and S4, uniformly stirring and mixing the silicone rubber microspheres and the dried
