Walnut shell powder plastic and preparation method thereof

Abstract

The invention provides walnut shell powder plastic and a preparation method of raw materials for the walnut shell powder plastic, relating to the field of plastic products. The walnut shell powder plastic is prepared from the following raw materials in parts by weight: 25 to 30 parts of walnut shell powder, 4 to 8 parts of talcum powder, 10 to 14 parts of diatomite, 40 to 55 parts of high-molecular polymer and 4 to 5 parts of plastic additive. The preparation method of the raw materials is characterized in that the walnut shell powder with the fineness of 300 to 350 meshes is mixed with the talcum powder, the diatomite, the high-molecular polymer and the plastic additive, and a mixture is extruded and granulated by a twin-screw mixing extruder, thereby forming the raw materials for preparing the walnut shell powder plastic. According to the walnut shell powder plastic and the preparation method provided by the invention, the use of non-degradable plastic can be reduced, a petroleum crisis is retarded, walnut shells as agricultural wastes are harmlessly treated, and the performance requirement and the application requirement of particular commodities or craft materials are met. Meanwhile, the walnut shell powder plastic provided by the invention can be used for processing products such as garbage cans or wastepaper baskets, and has good mechanical strength and excellent processing performance; the use of petroleum-based plastic can be reduced.

Description

technical field [0001] The invention relates to the field of plastic products, in particular to a walnut shell powder plastic and a preparation method thereof. Background technique [0002] With the great development of the plastics industry and a large number of applications of plastics, the problem of waste plastics is becoming more and more serious. Traditional plastics cannot be naturally degraded after being discarded and cause serious pollution to soil, groundwater and air. Direct recycling is half the effort and inefficient. The resulting white pollution has become a global problem, and the pressure on environmental protection is extremely huge. [0003] Walnut is one of the main economic plants, and its planting area is extensive. After the walnut matures, a large number of walnut shells become agricultural waste. Usually, they are simply incinerated, which pollutes the environment and creates safety hazards. [0004] The inventors of the present application creati...
