The invention discloses a preparation method of a lightweight composite board. The preparation method comprises following steps: raw material mixing, die material distribution, normal temperature pre-compressing, hot pressing solidification, cooling, die-opening, aging, trimming and cutting, thickness fixing and sanding, standard size cutting, polishing, and board surface composite treatment. Theobtained lightweight composite board is nontoxic, possesses no radioactivity, reaches flame resistance A2 grade, possesses oil resistance, stain resistance, mildew resistance, antibacterial performance, wear resistance, impact resistance, is abundant in color, uniform in color, high and uniform in texture density, extremely high in natural texture performance, strength, and hardness, and can be used for UV coating or other surface composite processing based on different application requirements; maintenance is convenient; seamless splicing can be realized; and the moulding can be changed. 本发明公开了种轻质复合板材的制备方法，步骤包括：原料混合、
