The invention relates to biodegradable material, specifically relates to a full biodegradable
fiber-reinforced
starch foaming tableware and a preparation method thereof. The foaming tableware is divided into two
layers of an outer layer and an
internal layer, the outer layer is prepared from the following components in
mass percent: 50 to 82 percent of cassava
starch, 5 to 20 percent of biodegradable short
fiber, 5 to 10 percent of biodegradable flexibilizer, 1 to 3 percent of compatilizer, 5 to 10 percent of
foaming agent, 1 to 5 percent of heat insulation agent and 1 to 2 percent of releasing agent. All the components are mixed and stirred uniformly, then biodegradable thin film is sprayed and coated on a mixture subjected to
hot press molding so that the full biodegradable
fiber-reinforced
starch foaming tableware is prepared. The tableware has the advantages that the strength is high, the rigidity is large, the
toughness is good, the foaming ratio is high, the foaming aperture is small, the heat insulation is good, the water-resistance and oil-resistance is good, and all the material can be fully biodegraded so as to be the best choice to substitute a foaming
polystyrene tableware.
