Abstract
The invention relates to the technical field of high polymer materials, and in particular to a completely biodegradable composite material which is characterized by consisting of the following raw materials in parts by weight: 30-80 parts of a starch-based resin composition containing starch and acrylic ester graft polymer, 10-50 parts of completely biodegradable resin and 1-6 parts of a plasticizer. On the basis that the degradation property and mechanical properties of the completely biodegradable resin are not degraded, due to addition of the starch, the cost of the composite material provided by the invention is greatly lowered. The cost of the completely biodegradable composite material provided by the invention is approximate to that of the conventional plastic, and thus the completely biodegradable composite material has relatively good competition advantages and wide market prospects.
