Abstract

The invention relates to a functional biodegradable material and a preparation method thereof and belongs to the field of starch modification technology. The functional biodegradable material is prepared from the following raw materials (by weight): 30-65 parts of bio-based resin, 0-10 parts of a vapor-phase rust inhibitor, 0.5-1 part of an auxiliary agent, 5-25 parts of a plasticizer and 0-80 parts of plastic starch. The functional biodegradable material has the following advantages: raw material cost is low; degradation period and rust-proof life are controllable; mechanical properties are high; and energy is saved and the environment is protected. Meanwhile, the invention provides a simple and feasible preparation method, which is beneficial to industrial production.

Description

technical field [0001] The invention relates to a functionalized biodegradable material and a preparation method thereof, belonging to the technical field of starch modification. Background technique [0002] Commercially available vapor phase antirust materials include vapor phase antirust paper, vapor phase antirust liquid and petroleum-based vapor phase antirust film, which play an important role in the antirust packaging of metal materials. However, most of these products use petroleum materials such as polyethylene and polypropylene as carriers, and these products cannot be recycled, so they cause white pollution, which is an urgent problem to be solved for environmental protection. For existing barrier packaging materials, the degradation cycle cannot be adjusted and controlled artificially, and the mechanical properties are often not up to standard. [0003] Therefore, there is an urgent need to develop and improve functionalized biodegradable materials. Contents o...
