Description

technical field [0001] The invention relates to the technical field of biodegradable material processing, in particular to a fully degradable bio-based composite material product and a preparation method thereof. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It has medium resistance to deformation and is between fiber and rubber. Agents, colorants and other additives. [0003] As an important organic synthetic polymer material, plastics are widely used and indispensable items in people's daily life. Since plastic products such as polyethylene do not have degradability, discarded plastic products can easily form "white garbage", which in turn has a huge negative impact on the living environment and the ecological environment. [0004] With the continuous advancement of science and technology, degradable composite products gradually appear in people's life a...
