The invention discloses an anti-deformation soundproof PVC wood-plastic composite floor. The anti-deformation soundproof PVC wood-plastic composite floor comprises a PVC plate, venting holes, sound absorbing plates, keels and a non-slip layer. The PVC plate is internally provided with through holes, receiving holes are formed below the through holes, springs are disposed under the receiving holes,a moisture absorbing layer is disposed under the springs, the venting holes are located on the outer sides of the springs, and sealing blocks are disposed in the venting holes. The sound absorbing plates are located on the lower surface of the moisture absorbing layer, extruded sheets are disposed in the sound absorbing plates, and the keels are located on the lower surface of the PVC plate. A connecting groove is formed in the left side of the PVC plate, a connecting block is disposed on the right side of the PVC plate, and the non-slip layer is located on the upper surface of the PVC plate.The anti-deformation soundproof PVC wood-plastic composite floor is not prone to deforming and cracking, is stable and durable in structure, and has a moisture-proof function. The non-slip layer is arranged on the lower part of the PVC plate, the plate can be prevented from deforming due to damp, and the sound absorbing plates under the plate can absorb sound and play a role of soundproofing.
