Reinforced POM board and preparation method thereof

The invention relates to the technical field of board processing, in particular to a reinforced POM board and a preparation method thereof. The reinforced POM board is processed from a reinforced POM material, wherein the reinforced POM material comprises the following raw materials in parts by weight: 80-120 parts of POM resin, 10-30 parts of a reinforcing modifier, 15-25 parts of a plasticizer, 5-15 parts of a filler, 3-7 parts of a stabilizer, and 0.8-1.2 parts of a lubricating agent; the reinforcing modifier is a mineral filler treated by a silane coupling agent. The mineral filler treated by the silane coupling agent is used for modifying POM, so that the produced board has relatively high strength and warping deformation resistance. The reinforced POM board has relatively high strength and warping deformation resistance, good temperature resistance and weather resistance, high strength, excellent impact resistance, a good flame-retardant effect, good processing performance and excellent comprehensive pe
