The invention relates to an LSPC foamed sheet and a preparation method thereof, and belongs to the technical field of foamed materials. In order to solve the problems that an existing foamed stone-plastic plate is uneven in foam hole, insufficient in strength and prone to local collapse, a novel foam regulator is introduced into a PVC-based foaming system. According to the regulator, through hydrosilylation, ring opening and silane coupling reaction, a polysiloxane-alkyl ester functional structure is grafted on the surface of nano silicon dioxide, bubbles are induced to be uniformly nucleated by utilizing low surface tension of the functional structure, and bubbles are inhibited to be aggregated through an interface adhesion energy barrier, so that a uniform and fine closed-pore structure is formed. The density of the obtained LSPC board is reduced, and the LSPC board has excellent mechanical strength and high-temperature collapse resistance and is suitable for bearing, floor heating and other scenes.
