Abstract

The invention provides biodegradable high-temperature-resistant disposable tableware and a preparation method thereof. The tableware is prepared from the following components: modified starch, glass fibers, PLA, PBAT, mineral powder, poly (butylene succinate), mica powder, polyolefin, sodium abietate, magnesium aluminum silicate, polyethylene glycol, a biodegradation accelerant, a compatilizer, a foaming agent, a nucleating agent, a surfactant, a dispersing agent and a coupling agent. The preparation method comprises the following steps: mixing the materials, adding into a mold, and carrying out hot press molding on the mold. The tableware has the beneficial effects that the tableware prepared by mixing the modified starch, the glass fibers, the PLA, the PBAT, the mineral powder, the poly (butylene succinate), the mica powder, the polyolefin, the sodium abietate, the magnesium aluminum silicate, the polyethylene glycol, the biodegradation accelerant, the compatilizer, the foaming agent, the nucleating agent, the surfactant, the dispersing agent and the coupling agent has a better degradation effect and higher high temperature resistance; and the material can be applied to high-temperature food and can effectively protect the ecological environment.

Description
