Embodiment 1
[0031] An easy-to-clean and high-temperature-resistant polylactic acid composite material for environmentally friendly tableware is composed of the following parts by weight of raw materials: 35 parts of modified polylactic acid, 65 parts of plant fibers, 1.5 parts of sodium rosin, 0.3 parts of magnesium aluminum silicate, 25 parts of polyethylene glycol and 3 parts of polyethylene wax, and its preparation method comprises the following steps:
[0032]Add the weighed plant fiber and polyethylene glycol into the high-speed mixer and stir for 5-10min. The stirring speed is set to 320-450r / min, and the temperature is raised to 80-90°C. After mixing sodium rosin and modified polylactic acid, stir for 1-1.5h, after cooling to room temperature, add magnesium aluminum silicate and polyethylene wax in turn, after stirring for 10-15min, add the well-stirred mixture to the twin-screw extruder Melting and blending in the machine, extrusion, drawing and granulation, the easy-to-clean high...
