Title:
ECO-FRIENDLY THERMOPLASTIC STARCH AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/045483
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing an eco-friendly thermoplastic starch by using natural materials. The eco-friendly thermoplastic starch according to the present invention is prepared as an eco-friendly thermoplastic starch in uniform and fine powder state by mixing a starch, which is obtained from a plant through extraction, with honey having plasticity and lemon juice having a crosslinking property, and then passing same through a manual operation and a ball-mill process. The present invention can prepare a thermoplastic starch at low cost by using natural materials such as honey and lemon, which are readily available, and using an eco-friendly process, and also can prepare a thermoplastic starch which is eco-friendly and has excellent physical properties and strength.
