The invention discloses a low-cost bio-based fully-degradable film and a preparation method thereof, wherein the film comprises the following components in parts by mass: 15-25 parts of polyglycolide, 25-35 parts of corn starch, 35-55 parts of poly (butylene adipate/terephthalate), 5 parts of compatilizer, 3.75-12.25 parts of starch plasticizer, 0.5-0.7 part of citric acid, 0.75-1.25 parts of acetyl tributyl citrate, 0.3-0.5 part of maleic anhydride, 1640.2 parts of antioxidant and 0.2 part of 2- (2 '-hydroxy-5' -methylphenyl) benzotriazole. The low-cost bio-based fully-degradable film provided by the invention has the advantages that the bio-based content can reach more than 30%, the cost is lower, the tensile strength exceeds that of the traditional PE film, and the low-cost bio-based fully-degradable film has very important significance for solving the problem of white pollution and promoting the popularization and application of fully-biodegradable materials. |
