Abstract
Provided is a biopolymer composition, a preparation method for the same, and a bioplastic using the same, the biopolymer composition comprising at least 83.5 weight % of a copolymer resin of lactic acid (LA) and 3-hydroxypropionate (3HP), an antioxidant, and a lubricant, and the composition having an elongation percentage of at least 90% but not greater than 500%.
Claims10
A biopolymer composition, comprising:
- a copolymer resin of lactic acid (LA) and 3-hydroxypropionate (3HP) in an amount of 83.5% by weight or greater and less than 100% by weight;
- an antioxidant;
- and
- a lubricant,
- wherein the copolymer resin is a block copolymer of the lactic acid (LA) and the 3-hydroxypropionate (3HP) and a weight ratio of the lactic acid (LA) to the 3-hydroxypropionate (3HP) in the copolymer resin is in a range of 70:30 to 90:10,
- wherein elongation of the biopolymer composition is greater than or equal to 90% and less than or equal to 500%, and
- each of the antioxidant and the lubricant are present in an amount of 0.1 parts by weight to 0.5 parts by weight with respect to a total 100 parts by weight of the biopolymer composition.
