ADDITIVE COMPOSITION FOR BIODEGRADABLE PLASTIC, METHOD FOR PRODUCING THE SAME, AND BIODEGRADABLE PLASTIC USING THE SAME |
摘要 |
PURPOSE: Provided are an additive composition which substantially increases a biodegradability of plastic, and maintains heat resistance and durability of plastic, and prevents an environmental pollution, a method for producing the same, and a biodegradable plastic using the same. CONSTITUTION: The composition comprises hydroxyapatite formed by reacting 35-45 parts by weight(with respect to 100 parts by weight of water) of calcium oxide; and 10-50 parts by weight(with respect to the hydroxyapatite) of fatty acid. The hydroxyapatite has a porous crystalline structure, and the hydroxyapatite and the fatty acid are bonded by ionic bonding. The fatty acid is unsaturated fatty acid, unsaturated fatty acid ester that is an its ester compound thereof, or mixture thereof.
