Method for manufacturing plastic-substitute goods by using natural materials
First Claim
1. A method for manufacturing plastic-substitute goods by using natural materials, comprising the steps of:
- preparing a glue by mixing 20 wt % of a starch and 80 wt % of water together, and by heating this mixture;
washing and drying rice husks to a drying degree of 98%;
mixing the glue and the rice husks together so as to form a mixture of the glue and the rice husks, drying them to a drying degree of 98%, and crushing them to a size range of 0.01-0.1 mm;
mixing 85 wt % of the mixture of the glue and the rice husks and 15 wt % of rosin, and then mixing again 85 wt % of this whole mixture with 15 wt % of water to form a final mixture; and
molding the final mixture by a molding machine at a temperature of 100-350 degrees C. under a pressure of 5 Kg/Cm2 at a production frequency of 30-80 seconds per product.

Abstract
A method for manufacturing plastic-substitute goods by using natural materials is disclosed. Agricultural byproducts and wood byproducts such as rice husks, rice plant stems, corn plant stems, bean plant stems, wheat plant stems, saw dust and the like are crushed into a particular size, then the crushed particles are mixed with natural adhesives (such as corn starch, potato starch and the like), and are coated with rosin or natural resins, and then a molding is carried out by applying a pressure in a molding machine, thereby manufacturing the plastic-substitute goods. The raw materials of the present invention are readily available from the rural areas, and the molding is carried out at a temperature of 100-300 degrees C.
