Pet excrement disposal material and method for producing the same

Technical field

The present invention relates to a material for treating excrement of cats, dogs and other animals, and a method for producing the same. More specifically, the present invention relates to a pet excrement disposal material improved in water absorption and handling properties by granulating a mixture of inorganic particles and a water-absorbing resin, and a method for producing the same.

Background art

Cats, dogs, and other pet waste have been treated by absorbing the waste into powders such as sand, clay, and zeolite. However, these powders are poor in water absorption, so they tend to be moist and unsanitary due to excrement.

Therefore, as a method for improving the water absorption of these powders, a treatment material for excrement of pets made of dry granular pulp obtained by dewatering and granulating pulp (JP-III-62) — 60,491), containing at least 10% of plant material with high fiber content, at least 5% of starch or binder, and at least 20% of mineral material, and granulated. Waste material (JP-A-60-94, 042), which is made by granulating a mixture comprising papermaking power, a superabsorbent resin, and, if necessary, water-soluble inorganic salts. Excrement treatment materials and treatment materials made by mixing water-absorbent resin with powders of sand, clay, zeolite, etc. have been proposed. However, the former two use pulp and fibrous plant materials, and therefore have the disadvantage that they are expensive. On the other hand, the latter use vibrations of the transport tub to separate the water-absorbent resin and powder, or There was a problem in that the gel swollen by water absorption adhered to the feet of the kit during use.

Accordingly, an object of the present invention is to provide a novel cat excrement disposal material and a method for producing the same.

It is another object of the present invention to provide a pet excrement disposal material which does not lose its original performance due to vibrations during transportation or the like and does not adhere to the feet of the pet, and its production. It is to provide a method.
