Description

The present invention relates to an excrement disposal material comprising a water-absorbing granular material mainly composed of compressed and granulated organic fibers.

  Patent Document 1 is based on an excrement disposal material having a composite layer structure of a core portion having water absorption and a surface layer having water absorption covering the outer peripheral surface of the core portion, and the core portion is darker than the surface layer. By coloring with a dye or pigment and forming a lighter surface than the dark dye or pigment on the outer peripheral surface of the core, the excrement disposal material absorbs urine from cats, dogs, etc. The treatment material that contributes to the distinction before and after use is shown by seeing through or seeping through the surface layer where the dark color of the core is wet.

  That is, when the excrement disposal material absorbs urine from a cat or dog, the color of the core can be exposed through the surface layer. This makes it easy to discriminate between the unused portion (the portion where urination is not performed) and the replacement of only the used portion, which is economical.

  Patent Document 2 discloses a treatment material that contains a dye powder in the surface layer, dissolves the dye powder at the time of urination absorption and dyes the surface layer, and contributes to the discrimination before and after use.

  In other words, this invention is an invention in which the dye powder in the surface layer that is not colored (reacted) before use is dissolved in the urine by absorption of urine, and the surface layer is dyed with the color of the dye powder and used for discrimination. .

  The present invention makes it possible to distinguish before and after use by weakly reacting the dye before use and dyeing the surface layer in a light color, and after use, by strongly reacting the weakly reacted dye and coloring the surface layer in a dark color. Is to do.

The present invention provides an excrement treatment material comprising a core portion having water absorption and a surface layer having water absorption covering the outer peripheral surface of the core portion. By spraying the surface layer compounded material on the outer peripheral surface of the core portion through its wet moisture, the above dye is weakly reacted with the wet moisture on the outer peripheral surface of the core portion to dye the surface layer lightly, and during urination absorption, weak reacted with dye by the strong reaction give a coloration to the surface layer in the dark, in which a configuration that allows determination of the for front and Yogo.

For example, a blue dye (powder) is mixed in a surface layer compounding material, the surface layer compounding material is applied to a wet core part, and the blue dye is weakly reacted with the moist water in the core part to form a granular treatment material. The product is dyed light blue and sold as a product in the light blue coloring state.
Then, when the excretion water of the pet animal is absorbed, the weakly reacted dye is strongly reacted with the excretion water to dye the entire granular treatment material in a dark blue color. From the comparison between the light blue color and the dark blue color, It is designed to determine the later.

  Therefore, in the present invention, if the dye is simply mixed in the surface layer compound and sprayed onto the outer peripheral surface of the hydrocompressed granulated core portion, the dye is wetted on the outer peripheral surface of the core portion. By weakly reacting with moisture, the surface layer is dyed lightly, and when absorbing urine, the weakly reacted dye can be reacted strongly to cause the surface layer to develop a dark color. That is, the technical purpose of visually recognizing a change in color from a light color to a dark color and contributing to the discrimination before and after use can be effectively achieved.

In the manufacturing method of the excrement disposal material concerning the example of the present invention, it is a principal part expansion explanatory view showing typically the state where the peripheral surface of the core part is wet. It is a principal part expansion explanatory drawing which sprinkles the surface layer compounding material with which the dye was mixed in the outer peripheral surface of a nucleus part, and shows the state which the dye reacted weakly. It is a principal expanded explanatory view which shows typically the state in which the manufactured excrement processing material absorbed the urine of a cat or a dog, and the said weakly reactive dye reacted strongly. It is sectional drawing which outlines the apparatus which sprinkles a surface layer to the core part by which the said compression granulation was carried out. It is a flowchart which outlines the manufacturing process of the granular excrement disposal material concerning the Example of this invention.

The present invention is based on an excrement treatment material in which the outer peripheral surface of the core portion is covered with a water-absorbing surface layer after hydrocompression granulation of the water-absorbing core portion, and a dye is mixed in the surface layer compounding material. Then, the surface layer compounding material mixed with the dye is sprayed on the outer peripheral surface of the core portion through the wet moisture, and the dye in the surface layer is weakly reacted with the wet moisture on the outer peripheral surface of the core portion, so that the surface layer When the urine is absorbed by absorbing the urine by causing the weakly reacted dye to react strongly and causing the surface layer to develop a dark color, the change from the light color of the surface layer to the dark color is used. Discrimination after use is possible.

Hereinafter, the present invention will be described in detail with reference to the preferred embodiments shown in FIGS. 1 to 5. The excrement disposal material according to the embodiment is a water-absorbent granule mainly composed of compression-granulated organic fibers. In particular, an excrement treatment material comprising a composite layer structure of a core portion and a surface layer so that the surface layer is colored when absorbing urine is developed.

  The excrement disposal material having the above-mentioned composite layer structure is prepared by spraying a water-absorbent surface layer compounding material on the outer peripheral surface of the core portion through wet moisture after hydrocompression granulation of the core portion having water absorption. Thus, a composite layer structure is formed.

  Under this example, as shown in FIGS. 1 to 3, a powdery dye 3 (for example, blue dye powder) is mixed in the compounding material of the surface layer 2, and the surface layer 2 in which the dye 3 is mixed. Is applied to the outer peripheral surface of the core portion 1 through the wet moisture 4 to cause the dye 3 mixed in the surface layer 2 to weakly react with the wet moisture 4 on the outer peripheral surface of the core portion 1. When the surface layer 2 itself is dyed in a light color (for example, light blue) and urination is absorbed, the weakly reactive dye 3 reacts strongly with a sufficient amount of urine water, and the surface layer 2 is darkened (for example, a dark color). Blue).

  Therefore, under the present embodiment, in the process of forming the surface layer 2, the dye 3 weakly reacts to dye the surface layer 2 itself lightly and absorbs urine, this time causing the weakly reacted dye 3 to react strongly. In this way, the surface layer 2 can be colored deeply to contribute to the discrimination before and after use. Here, it is as follows when the compounding example of the core part 1 and the surface layer 2 in a present Example is shown. The present invention is not limited to this blending example.

<Second compounding example of surface layer> (weight ratio)
Organic fiber 71-97.9%
Water-absorbing polymer 1-9%
Starch or CMC 1-19.999%
Dye 0.1-0.001%

  When the water-absorbing polymer in the surface layer blending material absorbs moisture and swells to form a jelly, it interferes with good coloring of the light and dark colors of the surface layer 2, so the first and second blending examples of the surface layer 2 As shown in Fig. 2, it is preferable that the water-absorbing polymer has a poor blending of 0 to 9%.

Depending, the excretions treating material of this embodiment, before use, since the light blue mentioned above appear as the color of the surface layer 2, thereby, the light commercial value in the blue is enhanced, in use, Cat Ya When the urine 5 of a dog or the like is absorbed, the weakly reacted dye 3 in the surface layer 2 reacts strongly with the urine moisture, and this time, the surface layer 2 appears dark blue. As a result of the determination being very easy, only the used part can be exchanged.

  In addition, the core part 1 is hydromixed and granulated with the compounding material of the core part 1, and the outer peripheral surface of the core part 1 after granulation is wet. In this embodiment, since the wet moisture 4 on the outer peripheral surface of the granulated core portion 1 is used to cause a weak reaction of the dye 3, the dye 3 is simply mixed under this embodiment. There is also an advantage that the weak reaction of the dye 3 can be automatically obtained by simply applying the compounded material of the surface layer 2 to the outer peripheral surface of the wet core portion 1.

  As shown in FIG. 5, after compressing and granulating the core portion 1, water is sprayed to wet the outer peripheral surface of the core portion 1 (a liquid in which a water-soluble adhesive typified by polyvinyl alcohol is diluted). (Including the case where the core portion 1 is sprayed and wetted by spraying), and then the surface layer 2 compounding material can be sprayed. After the surface layer 2 is formed, it is dried by applying hot air.

The above-mentioned spraying method will be described below together with the apparatus.
As shown in FIG. 4, the rotary drum 6 is granulated by a compression granulator and the wet core portion 1 is supplied via a conveyor 7, and the dye 3 is mixed via a conveyor 8 such as a screw conveyor. The surface layer 2 blended material is supplied.
The wet core portion 1 rolls and stirs as the rotary drum 6 rotates, and the wet layer 4 wets the outer peripheral surface of the wet core portion 1. It is applied to the outer peripheral surface.

  Further, under the present embodiment, when the surface layer 2 is formed, it is necessary to reduce the amount of the water-absorbing polymer in the surface layer 2 because the dye 3 is weakly reacted. In the second blending example, the amount of organic fiber is increased.

This onset Ming, without coloring the core moiety 1 itself, viewing the changes to dark after use from light-colored before use of the surface layer 2, inexpensive excretion which facilitates discrimination of used parts and unused portions A material processing material can be provided.
