Embodiment Construction

[0022] Now, according to the present invention, a method for producing plastic substitutes using natural materials is described below with practical examples.

[0023]

[0024] Wash the rice husks. Dry the washed rice husk to a dryness of 98%.

[0025] Simultaneously, mix by the starch of 20% (weight) and the water phase of 80% (weight) ratio, stir mixture, so that starch and water can be mixed together equably;

[0026] After confirming the stirring result, slowly heat the mixture to 100°C, and then start the aging process until gelatinized. The mixture will not burn when heated slowly.

[0027] Make sure that the glue does not clump together so that the desired stickiness of the glue is maintained;

[0028] The dried rice husk is mixed with the glue, and then stirred so that the rice hull and the glue can be completely mixed together.

[0029] After confirming that rice husk and glue are fully mixed together, the mixture is dried to 98% dryness, and here, the ratio of ...

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 and the washed and dried sludge produced from the alcoholic factory 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 melamine resin or urea 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.

Description

technical field [0001] The present invention is about a method of making plastic substitutes by utilizing natural materials. Specifically, the present invention is a method of using natural materials to manufacture plastic substitutes, some agricultural and wood by-crops, such as rice husks, rice straw, corn stalks, bean stalks, wheat straw, sawdust, etc., as well as wine The washed and dried distiller's grains produced by the factory are crushed into fine powder, and then mixed with natural binders (such as corn starch, potato starch, etc.). Then it is coated with melamine resin or urea resin, and then hot-pressed in a mold to create a plastic substitute for natural materials. Background technique [0002] Every day there is a wide variety of goods made of plastic materials. Moreover, they come in a variety of shapes and uses, and are constantly being added. However, plastics are highly flammable, so they burn quickly in the event of a fire before it can be extinguished....
