Since the waterproof layer 10 is made of thin vinyl, the urine can be prevented from flowing out to the floor of the room. The nonwoven fabric or the paper absorbs urine while the nonwoven fabric or paper has a predetermined thickness. An absorbent made of a high absorption polymer is added to the absorbent layer 20 in order to increase the water absorption rate and to make the urine gel.

In this embodiment, the water barrier wall 30 is formed by applying paraffin wax on a linear line and absorbing the liquid paraffin wax in the absorbent layer 20 by heating the liquid paraffin wax to a melting temperature (about 50 ° C) And the coating roller for coating is rotated on the absorbent layer 20 to form the water-containing wall 30.

1 and 2, the defecation pad 1 according to the present invention is rolled in a roll state and has a constant width (about 30 to 40 cm) 30 ~ 40cm) is formed in the perforated line (L) is formed so that each piece is used to remove one by one.

3, the water barrier wall 30 is formed to have a width of about 1 to 2 mm by the height of the absorbent layer 20, and the water barrier wall 30 is formed in a lattice form (And the protective layer), which is different from that of the conventional simple waterproof layer and the defecation pad made of only the absorbent layer (and the protective layer). As a result, the pet is urinated by the plurality of compartment spaces S As shown in FIG. 4, only a certain range of compartment space (hatched section) around the position where the urine has fallen becomes wet and the urine does not go over or spread to the remaining space, so that the contamination area of the bowel pad can be minimized Thereby allowing the bowel pad to be used multiple times.

In this embodiment, since the paraffin wax penetrates into the absorbent layer 20 made of nonwoven fabric or paper, the water barrier wall 30 forms a kind of water barrier wall, thereby blocking the permeation of the urine through the water barrier wall , Each of the compartment spaces (S) by the height of the water level wall (30) forms a urine storage space having a floor composed of waterproof layers individually separated from each other and a wall surface of a predetermined height made of the water wall, The amount of urine that can be contained by the surface tension may be greater than the volume of the urine storage space.

In the present embodiment, the water-blocking wall 30 is formed only by the height of the absorbent layer 20. However, the present invention is not limited to this and the water- The amount of urine that can be contained in the compartment space S may be made substantially larger than the absorption capacity or volume of the urine storage space by applying the paraffin wax forming the paraffin wax to the upper surface of the absorbent layer 20 so as to protrude higher than the upper surface of the absorbent layer 20. [

The method of applying the paraffin wax so as to protrude higher than the upper surface of the absorbent layer 20 can be achieved by increasing the amount of paraffin wax or by appropriately adjusting the temperature of the applied paraffin wax, So as to be hardened at a predetermined height.
