The invention discloses an impact-resistant acrylic plate and a preparation method thereof. The acrylic plate is prepared from the following raw materials: methyl methacrylate, an azo compound, low-molecular wax, an ethylene-containing copolymer, glycidyl methacrylate, zinc stearate and an inorganic filler. The preparation method comprises the following steps: firstly, adding the ethylene-containing copolymer, the low-molecular wax, the methyl methacrylate and the methacrylic acid derivative into a stirring device, uniformly stirring, then adding the inorganic filler, the azo compound and the zinc stearate, uniformly mixing, extruding into a mold through a screw extruder, curing, and demolding to obtain the acrylic plate. The prepared acrylic plate is uniform in light, light in weight and easy to form, and has good impact resistance and toughness. 本发明公开了一种抗冲击亚克力板材及其制备方法，亚克力板材的原料包括：甲基丙烯酸甲酯、偶氮类化合物、低分子蜡、含乙烯的共聚物、甲基丙烯酸缩水甘油酯、硬脂酸锌、无机填料；制备方法步骤为首先将含乙烯的共聚物、低分子蜡、甲基丙烯酸甲酯、甲基丙烯酸衍生物加入搅拌装置中，搅拌均匀后再加入无机填料、偶氮类化合物、硬脂酸锌，混合均匀后，经螺杆
