Abstract

The invention provides disposable degradable plant fiber tableware and a preparation method thereof. The disposable tableware is prepared from the following raw materials in parts by weight: 90-100 parts of plant fibers, 20-30 parts of polyvinyl alcohol, 10-15 parts of modified starch, 4-8 parts of modified calcium carbonate powder, 20-40 parts of waterproof glue and 6-10 parts of carboxymethylcellulose. The preparation method comprises the following steps: crushing, grinding, mixing and dissolving, forming, gluing, drying and disinfecting the components to obtain a product. The disposable degradable plant fiber tableware is non-toxic and harmless and clean and sanitary. The preparation process is environment-friendly and pollution-free. The disposable degradable plant fiber tableware is high in degrading speed in a spontaneous combustion environment, and can be recycled if being immersed into soil as a fertilizer for plants. The disposable degradable plant fiber tableware are easily available and cheap in source of raw materials and regenerative, agricultural resources are comprehensively utilized favorably, and meanwhile, the air pollution problem caused by crop straw combustionis also alleviated, and the white pollution problem caused by use of a plastic product in a large range can be also alleviated effectively.

Description

technical field [0001] The invention relates to the technical field of disposable tableware, in particular to degradable plant fiber disposable tableware and a preparation method thereof. Background technique [0002] With the acceleration of people's life rhythm, social life is developing towards convenience and sanitation. In order to meet this demand, disposable foam plastic lunch boxes, plastic bags, chopsticks, water cups, etc. began to frequently enter people's daily life. The appearance of these easy-to-use and cheap packaging materials has brought many conveniences to people's lives. But on the other hand, these packaging materials are often discarded after use, causing "white pollution", causing environmental hazards, and becoming a huge environmental problem. White pollution refers to plastic products such as packaging bags made of polystyrene, polypropylene, polyvinyl chloride, etc. Throwing and throwing away is difficult to degrade, causing pollution to the ec...
