▎ 摘  要

NOVELTY - Preparing imitation ceramic alloy comprises (i) mixing graphite fluoride powder with glass fiber, maleic anhydride grafted and epoxidized polybutadiene resin, heating at 90-120℃ for 2-20 minutes to obtain first mixture, (ii) mixing barium sulfate, propylene-ethylene random copolymer, polybutylene terephthalate and stearate, heating to 240-260℃ to obtain second mixture, and (iii) adding the first mixture into the second mixture and stirring and keeping the temperature for 20-30℃ and granulating by pelletizer. USE - The method is useful for preparing imitation ceramic alloy used for food packaging material melamine bowl, disc, chopsticks and other food container, fast food industry and children catering industry. ADVANTAGE - The ceramic alloy: has the glossiness as high as 80 and has a strong repelling effect on oil stains, and more than 90% of the oil stains can be washed away with clear water.
