Abstract

The invention discloses a mold-proof antibacterial biological degradable plastic which is prepared from the following raw materials in parts by weight: 20-30 parts of potato starch, 3-5 parts of powdered cinnamon, 10-15 parts of potato stems and leaves, 3-5 parts of medical stone powder, 0.5-1 part of tannic acid, 0.5-1 part of boric acid, 1-2 parts of glycerol monolaurate, 3-5 parts of stearic acid, 1-2 parts of oleamide, 10-15 parts of acetyl tributyl citrate, 0.01-0.02 part of propyl p-hydroxybenzoate and 10-15 parts of polypropylene. The mold-proof antibacterial biological degradable plastic disclosed by the invention is good in mold-proof antibacterial property and biological degradability, good in thermal stability, certain in water resistance, good in use property, low in cost, simple and feasible in preparation process and safe and non-toxic, and the raw materials are easy to obtain.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a mold-proof and antibacterial biodegradable plastic and a preparation method thereof. Background technique [0002] At present, plastics have been widely used in all aspects of people's production and life. With the rapid development of the production and application of plastic products, the growth and consumption of plastics continue to increase. The vast majority of these plastic products are disposable, and waste plastics are extremely difficult to dispose of, leaving them in the environment as white garbage, which has threatened the balance of the ecological environment and the survival of humans, animals and plants. At the same time, shortages have occurred as the plastics industry is based on oil, and oil and gas resources are struggling to meet the growing global demand. In order to control white pollution, save energy and resources, and solve problems such as insuffic...
