Environmental-friendly disposable plant fiber tableware and preparation method thereof

Abstract

The invention discloses an environmental-friendly disposable plant fiber tableware which comprises the following raw materials in parts by weight: 10-18 parts of rice husk, 15-25 parts of corn straw, 10-20 parts of dried straw, 2-4 parts of starch, 8-14 parts of an adhesive, 4-10 parts of processing aids, 2-4 parts of plant albumen glue and 1-3 parts of plant polysaccharide. The disposable tableware disclosed by the invention is non-toxic and harmless, is relatively good in mechanical property, relatively good in mechanical strength and toughness, green and environmental-friendly in raw material, relatively good in degradability, wide in raw material source, safe and reliable in component, harmless to human bodies, low in cost, safe and convenient, simple in preparation process and has relatively high practical values and good application prospects, both resources are saved and environment pollution is reduced, and comprehensive utilization of agricultural wastes is achieved.

Description

technical field [0001] The invention relates to the technical field of environment-friendly tableware, in particular to a plant fiber environment-friendly disposable tableware and a preparation method thereof. Background technique [0002] At present, with the development of fast food and takeaway industries, the use of disposable tableware is increasing year by year. Disposable tableware on the market includes fast food boxes, chopsticks, spoons, etc. Fast food boxes are mainly composed of polymer compounds such as polystyrene and vinyl. It has the characteristics of being difficult to decompose, poisonous, and will not degrade after being buried in the soil for a hundred years. Because it is difficult to degrade, it will also cause new pollution to the environment. It is white pollution, it will emit a large amount of poisonous gas when it is burned, and it will not rot for two hundred years, causing serious harm to the environment. Foreign research results show that if ...

Problems solved by technology

Therefore, these "white pollution" not only waste resources, increase unreasonable economic pressure on the country and the people, but also leave a lot of problems for future generations

The chopsticks in disposable tableware are generally made of trees or bamboo. This kind of wooden chopsticks has caused a lot of forest land to be destroyed; and inferior chopsticks are not clean, just an illusion of hygiene

[0003] Although some starch-based degradable materials that have emerged in recent years have solved the problem of white pollution caused by foamed plastics, due to poor mechanical strength and poor plasticity, these degradable materials require two sets of mixing devices in production, and it is not easy to keep warm during the production process. , complex process lines, high production costs, and product quality that does not meet the requirements, so it cannot be widely used
