Abstract

The invention especially relates to a degradable antibacterial toy material and a preparation method thereof, belonging to the technical field of degradable materials. The degradable antibacterial toy material comprises a degradable antibacterial outer film and a degradable toy core blank. The degradable antibacterial toy material is characterized in that the degradable antibacterial outer film comprises deacetylated chitin, polymethylethylene carbonate, polyvinyl alcohol, polyhydroxybutyrate, stearic acid, a tetrabutyl titanate aid solution, etc.; the degradable toy core blank is straw; and the degradable antibacterial outer film is melted to form a thin film which coats the outer surface of the toy core blank to form a toy. According to the invention, deacetylated chitin, polymethylethylene carbonate, starch and the like are used as raw materials of the degradable antibacterial outer film; the prepared material has the characteristics of simple process, convenient operation, complete biodegradability and the like; and straw is used as the main component of the toy core blank and has the advantages of complete degradability and good processability.

Description

technical field [0001] The invention relates to the technical field of degradable materials, in particular to a degradable antibacterial toy material and a preparation method thereof. Background technique [0002] The world produces more than 100 million tons of plastics every year, and my country's plastics account for a large proportion. With the continuous growth of the use of plastics, the wastes of packaging plastics, agricultural plastics and various plastic products have become white garbage, causing serious environmental pollution. At present, the plastics used in toys mainly include polystyrene, polypropylene, polyethylene and so on. These plastics discarded after use exist in the natural environment for a long time because they cannot be degraded, causing serious white pollution, and most of the plastics used in toys do not have antibacterial properties. Problem, the research and development of degradable plastics has become a research hotspot in the world, so we...
