NOVELTY - Preparing colored crystal imitation jade and environmentally friendly quartz stone plates, involves (a) mixing 85-90 wt.% resin, 2-6 wt.% functional agent and 1-5 wt.% dispersant uniformly with a high-speed stirrer, heating and melting, using a double-screw extruder to extrude and granulate, where the melt mixing and dispersing extrusion temperature is 100-280℃, the functional agent comprises anion compound and graphene quantum dots/silver oxide/silver-zinc-cerium/silicon dioxide/graphene antibacterial powder; (b) adding quartz, modified resin, curing agent, coupling agent, luminous compound, aluminum hydroxide powder and color material, and stirring to obtain mixture; and (c) distributing mixture on the template, vibrating and forming, demolding, cutting, and arranging according to the preset pattern to obtain semi-finished product, and performing vibrating and forming, drying and forming on cloth for second time, and post-processing to obtain finished product. USE - The method is useful for preparing colored crystal imitation jade and environmentally friendly quartz stone plates. ADVANTAGE - The method enables to prepare colored crystal jade-imitated environmentally friendly quartz stone plate, has excellent antibacterial, purifying air and luminous performance, broadens the application range of the bionic quartz, and prevents smoking, generates toxic gas, and is safe to use.
