Coffee shell powder plastic as well as production process and coffee cup thereof

Abstract

The invention provides a coffee shell powder plastic and a production process thereof. The coffee shell powder plastic comprises raw materials of coffee shell powder, talcum powder, natural clay, a high-molecular polymer and a plastic additive at a weight part ratio of (20-35):(8-10):(4-6):(40-60):(4-5). The invention further provides a coffee cup. The coffee shell plastic provided by the invention is prepared by taking the coffee shell powder as a raw material, the agriculture waste coffee shells is subjected to harmless treatment, a novel coffee shell treatment method is provided, a conventional treatment method of incinerating the coffee shells is abandoned, environmental pollution caused by incineration is reduced, refuse reclamation of the coffee shells is achieved, and the economic values of the coffee shells are increased.

Description

technical field [0001] The invention relates to the field of plastic production technology, in particular to a plastic prepared by using coffee husk powder. 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. From the perspective of resource conservation, plastic products should be recycled as much as possible since the main source of plastic products is petroleum resources that are facing depletion. However, since the production cost of recycling at this stage is much higher than the direct production cost, it is difficult to do so ...

Problems solved by technology

[0003] Coffee is one of the main economic plants in Yunnan and other regions. A large number of coffee husks become agricultural waste, which are usually only incinerated, which pollutes the environment and creates safety hazards.

Chinese patent CN200910038366.7 discloses a degradable environmental protection material and its preparation method and application. The patent is made by mixing coffee husk or coffee bean dregs with food-grade solid rubber powder. The preparation process is to mix coffee husk powder and food-grade solid The glue powder is mixed evenly and then hot-pressed. This production process is relatively simple, and the prepared degradable environmental protection material has low strength, short service life, and relatively low economic value. This is because the coffee shell and food-grade solid glue powder the binding force is weak
