Abstract

The invention discloses an antibacterial antifungal and biodegradable plastic. The plastic is characterized by being prepared from the following materials in parts by weight: 20-30 parts of potato starch, 3-5 parts of cinnamon powder, 10-15 parts of potato stalks 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 oleic acid amide, 10-15 parts of acetyl tri-n-butyl citrate, 0.01-0.02 part of propyl p-hydroxybenzoate and 10-15 parts of polypropylene. The biodegradable plastic disclosed by the invention has good antibacterial, antifungal and biodegradable properties, good heat stability, certain water resistance, good use property and low cost, is prepared from easily-available materials according to a simple and feasible process, and is safe and nontoxic.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to an antibacterial and mildew-resistant 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 i...
