A disposable liquid-binding floor mat includes a water penetration layer, a water absorption layer, a water-proof layer and a self-adhesive layer. The water penetration layer is a thin piece of non-woven fabric and is superimposed on the water absorption layer. The water absorption layer is made of a hydrophilic thin plate and is superimposed between the water penetration layer and the water-proof layer. The water-proof layer is made of a water-proof film material and is superimposed between the water absorption layer and the self-adhesive layer. The self-adhesive layer is made of a self-adhesive material and is superimposed below the water-proof layer. The water penetration layer, the water absorption layer, the water-proof layer and the self-adhesive layer are bonded as an integrated non-sealed edge structure, and a deodorant is added into the water absorption layer.
