Problems solved by technology

[0002] At present, plastics are generally made of polymer compounds such as polystyrene, polypropylene, and polyvinyl chloride. Plastic products made of these polymer compounds are difficult to be degraded, resulting in the accumulation of garbage and difficult problems in elimination. After being treated as combustion energy, it will cause harmful gas pollution and acid rain, and the polyvinyl chloride component in the plastic is also toxic to a certain extent, causing splenomegaly and liver damage to people who use it for a long time. Plastic bags and other plastic products will also affect the water absorption of crops and inhibit the growth and development of crops after they are discarded in the farmland, resulting in a reduction in crop production

Abstract

The invention relates to the technical field of plastic production, in particular to environment-friendly full-degradable plastic and a production method thereof. The environment-friendly full-degradable plastic is prepared from the following components in percentage by weight: 1-3% of konjak flour, 4-7% of flour, 0.2-0.4% of glycerol, 3-5% of quick lime, 0.8-1.2% of polyvinyl alcohol, and 0.3-0.6% of a plasticizer, with the balance being water. The invention further discloses the production method of the environment-friendly full-degradable plastic. The method comprises the following steps: crushing konjak by a crusher, proportionally weighing the konjak flour and the quick lime powder, adding water, putting the obtained mixture into a water bath kettle, heating, stirring, decocting intoa porridge form, putting the obtained mixture into a mixer, proportionally adding the flour, the glycerol, the polyvinyl alcohol and the plasticizer, uniformly stirring, and granulating in drying andgranulating equipment. The method is reasonable in process, can eliminate harmful components in the plastic, has the characteristics of easy degradation and environmental protection, and does not cause environmental pollution.
