【発明の詳細な説明】
本発明は製紙カスと高吸水性樹脂とからなる混
合物を造粒、乾燥してなるペツトの排泄物処理材
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a PET excrement treatment material made by granulating and drying a mixture of paper waste and a superabsorbent resin.
ペツトの排泄物の処理は従来砂を用いこの砂を
容器内に敷き詰め適宜排泄物とともに砂をとりか
えることにより行なつてきた。しかしながら砂は
吸水性がないため放置したままにしておくと不衛
生であり、かつ排泄物の臭気がいつまでも残るた
め排泄のたびに取り替える必要があつた。しかも
排泄時にペツトが砂をかきまわすため砂が飛散し
室内が汚れるという問題も生じていた。 Disposal of pet excrement has conventionally been carried out by using sand, placing the sand in a container, and replacing the sand with the excrement as appropriate. However, sand does not absorb water, so it is unsanitary to leave it as it is, and the odor of excrement remains forever, so it has to be replaced every time one defecates. Moreover, when the pets defecate, they stir up the sand, causing the sand to fly around and make the room dirty.
これら問題点を解消するためパルプに適宜水を
加え、これを乾燥成形して小塊の粒状部材に形成
したものが提案されている。このパルプからなる
排泄物処理材においては、排泄物を吸収した部分
が乾燥後固形状となるため、その部分だけを取出
し水洗トイレなどにながして処理することが可能
であり、排泄物の処理が非常に簡単になつてい
る。しかし、なお吸水性に問題を残しており、か
つ湿潤状態が長く続くという問題点は解消されて
いない。 In order to solve these problems, it has been proposed to add water to pulp as appropriate and then dry and mold the pulp to form a small granular material. In excrement disposal materials made of this pulp, the part that absorbs excrement becomes solid after drying, so it is possible to remove only that part and place it in a flush toilet, etc., for disposal. It's getting very easy. However, the problem of water absorption still remains and the problem of remaining wet for a long time has not been solved.
本発明は叙上の問題点に着目してなされたもの
であり、製紙カスと高吸水性樹脂とからなる混合
物あるいは製紙カスの一部を水溶性無機塩類で置
き換えてなる混合物を造粒、乾燥してなるペツト
の排泄物処理材に関し、高吸水性樹脂が迅速に多
量の水分を吸収するため、吸水部分が少量です
み、かつ表面がサラサラした状態を長く保持する
ことができる。さらに本発明の排泄物処理材は高
吸水性であること、また水分散性ないし水活性物
質で構成されているためトイレなどで処理するば
あい、排泄物とともに廃棄する量がパルプに比較
して少量でよく、このため非常に経済的である。 The present invention has been made in view of the above-mentioned problems, and involves granulating and drying a mixture of paper manufacturing waste and super absorbent resin, or a mixture obtained by replacing a portion of paper manufacturing waste with water-soluble inorganic salts. Regarding PET's excrement treatment material, the superabsorbent resin quickly absorbs a large amount of water, so only a small amount of water is absorbed, and the surface can remain smooth for a long time. Furthermore, the excrement treatment material of the present invention has high water absorption properties and is composed of water-dispersible or water-active substances, so when disposed of in a toilet etc., the amount to be disposed of along with excrement is smaller than that of pulp. Only a small amount is required, making it very economical.
また、製紙カスはパルプに比べ繊維長が短いた
め、造粒時に密に固まつて造粒物の密度が高くな
ること、製紙カス中にはクレーなどの種々の填料
が含まれていること、水溶性無機塩類はパルプに
比べ比重が大きいことなどの点から、造粒乾燥さ
れた本発明の排泄物処理材は密度の高いものであ
り、したがつてペツトが排泄時にかきまわしても
パルプのみからなる従来のものに比べて飛散しに
くい。 In addition, because paper waste has a shorter fiber length than pulp, it hardens densely during granulation, resulting in a higher density of granules; paper waste also contains various fillers such as clay; Water-soluble inorganic salts have a higher specific gravity than pulp, so the granulated and dried excrement treatment material of the present invention has a high density, so even if the pet stirs it up when defecating, it can only be made from pulp. It is less likely to scatter compared to conventional products.
本発明の排泄物処理材は、製紙カス97〜85％
（重量％、以下同様）と高吸水性樹脂３〜15％と
からなるものが好ましく、また製紙カスの一部を
水溶性無機塩類で置き換えるばあい、製紙カス15
〜75％、高吸水性樹脂５〜15％および水溶性無機
塩類20〜80％とするのがよい。 The excrement treatment material of the present invention has a content of 97 to 85% paper waste.
(wt%, the same applies below) and 3 to 15% of super absorbent resin are preferable, and when a part of paper waste is replaced with water-soluble inorganic salts, paper waste of 15% is preferable.
-75%, superabsorbent resin 5-15% and water-soluble inorganic salts 20-80%.
本発明に用いられる製紙カスとは、たとえば排
出されるスラツジ、またはパルプ粉粋工場から排
出される微粉などであり、繊維長が１mm以下程度
のものを主体とするものである。これら製紙カス
は再生利用が困難で従来その廃棄処理に問題を生
じているものであるため非常に安価に入手でき、
排泄処理用材として好適である。 The paper waste used in the present invention is, for example, discharged sludge or fine powder discharged from a pulp mill, and is mainly comprised of fibers with a length of about 1 mm or less. These paper wastes are difficult to recycle and have traditionally caused problems in disposal, so they can be obtained very cheaply.
Suitable as a material for excrement disposal.
本発明に用いられる高吸水性樹脂（以下SAP
という）は0.9％食塩水に浸漬したときの吸水量
が該SAP1ｇに対し30ｇ以上であるものであり、
たとえばスミカゲル（住友化学工業(株)製のポリア
クリル酸ナトリウム）、サンウエツト（三洋化成

ラフト共重合体）などがあげられる。 Super absorbent resin (hereinafter referred to as SAP) used in the present invention
) has a water absorption amount of 30 g or more per 1 g of said SAP when immersed in 0.9% saline solution,
Examples include Sumikagel (sodium polyacrylate manufactured by Sumitomo Chemical Co., Ltd.) and Sunwet (starch-sodium acrylate graft copolymer manufactured by Sanyo Chemical Industries, Ltd.).
このSAPの添加量は３〜15％、水溶性無機塩
類を配合するときは５〜15％が好ましく、それら
未満では吸水性が不充分となり、15％を超えると
原料混合時に添加する水をSAPが吸収しすぎて
造粒に必要な流動性が失われ、造粒が困難とな
る。また流動性を与えるため多量の水を加えると
添加混合物がネバつき造粒が困難となり、かつ造
粒ができたとしても乾燥に長時間を要し不経済で
ある。 The amount of SAP added is preferably 3 to 15%, and 5 to 15% when water-soluble inorganic salts are blended.If it is less than that, the water absorption will be insufficient, and if it exceeds 15%, the water added when mixing raw materials will be added to SAP. If too much is absorbed, the fluidity necessary for granulation is lost, making granulation difficult. Furthermore, if a large amount of water is added to provide fluidity, the added mixture becomes sticky and granulation becomes difficult, and even if granulation is possible, it takes a long time to dry, which is uneconomical.
本発明に用いられる水溶性無機塩類は混合時
SAPが混合中の水分を吸収しすぎ、流動性を失

硫酸バンド、硫酸マグネシウム、メタケイ酸ソー
ダなど安価なものが好ましい。 The water-soluble inorganic salts used in the present invention are
This prevents SAP from absorbing too much water during mixing and losing fluidity, and also serves as a filler for the mixture. In addition, it must be water-soluble in order to be treated in flush toilets, etc. Specific examples include sodium sulfate,
Inexpensive materials such as aluminum sulfate, magnesium sulfate, and sodium metasilicate are preferred.
水溶性無機塩類を添加するばあいには20〜80％

ため混合物は非常に粘性が増し、造粒が困難とな
る。 20-80% when adding water-soluble inorganic salts
However, if it is less than 20%, paper waste or
The ratio of SAP increases and the mixture becomes less fluid, making granulation difficult. Furthermore, if the content of water-soluble inorganic salts exceeds 80%, the amount of paper waste added will decrease, resulting in a very viscous mixture, making granulation difficult.
本発明の処理材は、製紙カス、水溶性無機塩
類、高吸水性樹脂に造粒に必要な流動性を与える
ため適量の水を加えて混合し造粒して乾燥する。
造粒法としては通常の押出機を使用し、乾燥後の

乾のいずれでも可能である。 The processing material of the present invention is prepared by adding an appropriate amount of water to paper waste, water-soluble inorganic salts, and superabsorbent resin to give them the fluidity necessary for granulation, mixing them, granulating them, and drying them.
For the granulation method, an ordinary extruder is used, and the die hole and cut length of the extruder are selected so that the granules have a spherical shape with a size of 3 to 10 mm after drying. Further, drying can be done by heating or air drying.
本発明のペツトの排泄物処理材の形状は球状の
