Abstract
The present invention discloses a compound degradable cassava powder material, a preparation method thereof and an application thereof. The degradable material is prepared from the following raw materials: cassava powder, CO2 aliphatic polycarbonate, methyl methacrylate, cis-butylene rubber, polyvinyl acetate, modified starch, urea, glyoxal, polymer wax and plasticizing agents; finished products are preapred from the raw materials through the processing steps of mixing granulation, forming, disinfection, etc. The present invention has the following advantages: polycarbonate is used to replace petroleum products so as to reduce production cost and save petroleum resources; the raw materials contain large amounts of full powder of cassava powder, so that the fruit, the stems and the leaves of the cassava are all utilized, which raises the added value of the cassava powder; the compound degradable cassava powder material has favorable machining property and wide application, and can be used for various aspects such as packaging materials of industrial products and civilian goods, tableware, etc.; the material has the advantages of complete degradation in natural environment, no public nuisance and no poison and odor, and is favorable to environmental protection.
