The invention provides a high-strength PVC foam board for a bus floor. The foam board comprises a bonding layer, a buffer layer, a soft layer and a contact layer which are sequentially arranged from bottom to top, and a hard layer is further included. The hard layer is arranged between the soft layer and the contact layer, the hard layer is a foam plate part made of a PVC material, the contact layer is a graphene plate part, a lower surface of the graphene plate part is tightly attached to an upper surface of the foam plate part, the lower surface of the foam plate part is tightly attached tothe upper surface of the soft layer, the buffer layer is provided with a containing cavity, and the containing cavity is filled with absorbent cotton and activated carbon; and the containing cavity comprises a curved surface wall with a water through hole, a first cavity part and a second cavity part, the first cavity part and the second cavity part are arranged on the two sides of an inclined wall part of the curved surface wall and extend in a staggered mode in an axial direction, the first cavity part is filled with the absorbent cotton, and the second cavity part is filled with the activated carbon. Compared with the prior art, by using the foam board of the invention, through arranging the contact layer of the graphene plate part, vulnerability is reduced, and a service life is prolonged; maintenance cost or replacement cost is reduced; in addition, the foam board has a water purification function and is convenient to use.

    本发明提供一种高强度公交车地板用PVC发泡板,包括依次从下至上设置的贴合层、缓冲层、软质层、接触层,还包括硬质层,硬质层设置于软质层和接触层之间,硬质层为PVC材质制成的发泡板部,接触层为石墨烯板部,该石墨烯板部下表面紧贴于发泡板部上表面,发泡板部下表面紧贴于软质层上表面,缓冲层具有容置腔,容置腔内填充有吸水棉和活性炭;其中容置腔包括具有通水孔的曲面壁、置于曲面壁的倾斜壁部两侧相互沿轴方向交错延伸的第一腔部和第二腔部,吸水棉填充于第一腔部,活性炭填充于第二腔部。本发明与现有技术相比,通过设置石墨烯板部的接触层,降低易损性,延长使用寿命;且降低维护成本或更换成本;此外具有净水功能,使用方便。
