The invention discloses a multifunctional pattern plate. The multifunctional pattern plate comprises the following components in parts by weight: 20-35 parts of an acrylic resin base material, 5-20 parts of epoxy resin, 40-60 parts of quartz sand, 4-10 parts of waste fine powder of glass fiber reinforced plastic, 4-7 parts of composite fiber powder, 4-7 parts of nano titanium dioxide powder, 0.2-0.5 part of a toughening agent, 2-8 parts of an accelerator, 1-3 parts of a flame retardant and 2-5 parts of natural mineral pigment. According to the invention, the raw materials are regulated and optimized, the functional raw material components are added at the same time, and the functional raw material components can act synergistically, so that the prepared pattern plate not only has excellentmechanical properties, but also has the special functions of flame retardant, explosion protection, sound insulation, mould prevention, bacteria resistance and the like, and the application range isgreatly widened. The invention also discloses a preparation method of the multifunctional pattern plate, the process is simple, and large-scale industrial production is facilitated.
