Abstract
Description
ここで、パルプを主体として構成される粒状物は、ベントナイト等の鉱物を主体として構成される粒状物に比して軽いため、飛び散りやすい。そのため、パルプを主体として構成される粒状物により動物用トイレ砂を構成する場合、飛び散りを防ぐためには、粒状物の粒度を大きくすることが好ましい。
本実施形態の動物用トイレ砂は、パルプを主体として構成され吸水性を有する複数の粒状物により構成される。
本発明では、複数の粒状物は、長粒及び短粒を含む。
本明細書においては、10mmメッシュの篩を通過し、4mmメッシュの篩を通過しない粒状物を4mm以上10mm未満の粒度の粒状物とする。
核部は、粉末状又は短繊維状のパルプを主体として構成され、粉末状又は短繊維状のパルプが押出造粒機等により造粒されて形成される。
核部は、パルプに加えて他の材料を含んでいてもよい。他の材料としては、高吸水性樹脂、香料、及び抗菌剤等が挙げられる。
被覆層を構成する他の材料としては、澱粉、香料、及び抗菌剤等が挙げられる。
澱粉としては、タピオカスターチ、及びコーンスターチ等を用いることができる。澱粉は、粒状物が尿を吸収した場合における粘着性を向上させる。
香料及び抗菌剤は、核部に用いられるものと同様のものを用いることができる。
被覆層における高吸水性樹脂の含有量は、尿を吸収した場合に粒状物の固化性を発現させ、かつ、高吸水性樹脂が膨潤してゲル化することによる核部における吸水性の阻害を起こさせないようにする観点から、好ましくは1%~20%、より好ましくは4%~15%である。
また、長粒及び短粒の合計に占める短粒の割合を50%以下とすることで、動物用トイレ砂を飛び散りにくくできる。
尚、長粒及び短粒以外の粒状物としては、例えば、長粒又は短粒が割れて細かくなった粒状物、及び造粒時に複数の粒状物が固着して形成された粒度の大きい粒状物が挙げられる。
動物用トイレ砂に占める他の材料を主原料とする粒状物の含有量は、重量比において10%以下であることが好ましく、5%以下であることがより好ましい。
使い捨ておむつ製造時の廃材から取り出される、主としてパルプからなり、高吸水性樹脂を含む原料を粒度φ5mm~φ15mmで粉砕し、造粒水分率が10~40%となるように水を加えた。
混合後、混合物を押出造粒機を用いて造粒した。ここで、スクリーンから押し出した混合物を8mm間隔で切断して長粒想定の核部を得、また、スクリーンから押し出した混合物を4mm間隔で切断して短粒想定の核部を得た。
次いで、得られた長粒想定の核部及び短粒想定の核部の表面に、粉砕したパルプ55~90%、高吸水性樹脂5~40%、澱粉5~40%の割合で混合した粉末をふりかけて被覆層を形成し、長粒想定及び短粒想定の粒状物を得た。次いで、得られた長粒想定及び短粒想定の粒状物を、乾燥機で水分率10%以下まで乾燥させた。
そして、得られた長粒想定及び短粒想定の粒状物を、それぞれ、4mmメッシュの篩にかけて、この4mmメッシュの篩を通過した粒状物を除去した。更に、4mmメッシュの篩に残った粒を縮分機(筒井理化学器械製)で均等に縮分した上で、粒状物の径及び長さをノギスにて測定した。
この得られた長粒想定及び短粒想定の粒状物それぞれの直径及び長さを、以下の表1に示す。
尚、造粒された粒状物の直径及び長さには、ばらつきが生じることが一般的であるため、ここでは、測定に使用した長粒想定及び短粒想定(N=50)の直径及び長さの平均値を少数第2位で四捨五入して得た値をそれぞれ、長粒想定及び短粒想定の直径及び長さとした。
実施例1~8、比較例1~4の動物用トイレ砂を、それぞれ、深さが10cm以上となるようにビーカーに収容する。
次いで、動物用トイレ砂が収容されたビーカーに、擬似尿として、22℃の生理食塩水(0.9% NaCl aq)20mlを、動物用トイレ砂の上面の上方3cmの位置から10秒間かけて滴下する。
擬似尿の滴下後10分間放置し、その後、得られた固まりの深さを測定した。また、固まりの深さが50mm未満の場合を◎、50mm以上70mm未満の場合を○、70mm以上の場合を×と評価した。
上記固化深の測定において得られた固まりをペット用のスコップですくい取った後、10秒間左右にゆすり、剥がれ落ちた粒状物の重量を測定した。この剥がれ落ちた粒状物の重量を、ゆする前の固まりの重量で除して剥がれ率を求めた。また、剥がれ率が5%未満の場合を◎、5%以上10%未満の場合を○、10%以上の場合を×と評価した。
実施例1~6、比較例1~4の動物用トイレ砂10gを50cmの高さから平板上に自由落下させ、動物用トイレ砂が飛び散った状態を目視にて評価した。
評価は猫飼育者10名によって行い、動物用トイレ砂が飛び散った状態を許容できる人数が8名~10名の場合を◎、4名~7名の場合を○、0名~3名の場合を×と評価した。
