Abstract: A degradable plastic and a manufacturing method thereof are provided. The degradable plastic is made by mixing plastic, dry crop straw scraps and additives and extruding the mixture into granules with a double-screw extruder. The weight fraction of the plastic, crop straw scraps and additives is 63-73 wt %, 23-33 wt % and 4-6 wt % based on the total weight of raw material. The obtained granules are even, stable and can be used to manufacture daily necessities such as dishware, containers, stationery and bags having smooth surface, high strength, excellent toughness and comfortable hand feeling.

Abstract: A straw plastic and the preparation method thereof are disclosed, wherein the crops straw with the length of 1.5˜2.0 mm is dried and mixed with plastic and plastic additive, and then extruded and palletized with twin screw extruder. The granular material of the invention has even particle size and stable state, and can be made into film, sheet or injection moulded product with molding process such as blow molding, drawing or injection molding. The product appears the color of natural wood, has the texture of plant fiber on the surface, and has good surface finish, high strength, good toughness, and comfortable hand feeling. The invention reduces the environmental pollution resulted from the discarding of undegradable plastic and achieves the full utilization of resource.
