Description
本発明は、人や動物の尿その他の液体を吸収する吸水処理材に関する。 The present invention relates to a water-absorbing treatment material that absorbs human and animal urine and other liquids.
特許文献１には、吸水処理材の一種である排泄物処理材が記載されている。この排泄物処理材においては、粒状芯部と、それを覆う被覆層部とが設けられている。被覆層部は、使用時に尿等の液体を吸収した排泄物処理材どうしを付着させて塊状にする機能を有する。かかる被覆層部は、接着性材料を含んで構成されている。
このように被覆層部に接着性材料を含有させることにより、使用時に吸水処理材どうしを付着させて塊状にする機能を高めることができる。しかしながら、充分な塊状化機能（固まり強度）を得るためには、相当量の接着性材料が必要であり、それに伴い被覆層部に相当程度の厚みをもたせる必要があった。このことは、吸水処理材の製造時に、被覆層部を構成する材料（被覆材料）の使用量を増大させ、ひいては製造コストの上昇につながる。 In this way, by containing the adhesive material in the coating layer portion, it is possible to enhance the function of adhering the water-absorbing treatment materials to each other during use. However, in order to obtain a sufficient agglomeration function (cohesive strength), a considerable amount of adhesive material is required, and accordingly, the coating layer portion needs to have a considerable thickness. This increases the usage amount of the material (coating material) constituting the coating layer portion at the time of manufacturing the water-absorbing treatment material, which leads to an increase in manufacturing cost.
本発明は、上記課題に鑑みてなされたものであり、使用後の固まり強度が高く、かつ低コストで製造することが可能な吸水処理材を提供することを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a water-absorbing treatment material that has high lump strength after use and can be manufactured at low cost.
本発明による吸水処理材は、液体を吸収する吸水処理材であって、粒状芯部と、上記粒状芯部を覆うように設けられ、接着性材料を含有するとともに、厚みが１ｍｍ未満である被覆層部と、を備え、当該吸水処理材は、上記液体を吸収した時に崩壊し、崩壊した当該吸水処理材は、上記被覆層部の上記接着性材料によって塊状化されることを特徴とする。 The water-absorbing treatment material according to the present invention is a water-absorbing treatment material that absorbs liquid, and is provided so as to cover the granular core portion and the granular core portion, contains an adhesive material, and has a thickness of less than 1 mm. A layer portion, and the water-absorbing treatment material is collapsed when the liquid is absorbed, and the water-absorbing treatment material collapsed is agglomerated by the adhesive material of the coating layer portion.
この吸水処理材は、液体を吸収した時に崩壊するように構成されている。かかる構成により、被覆層部中の接着性材料は、広範囲に行き渡るようになるため、効率良く塊状化機能を発揮することができる。このため、少量の接着性材料であっても、充分な塊状化機能が発揮される。それゆえ、被覆層部を１ｍｍ未満という薄さにしても、充分な固まり強度が得られる。したがって、製造時における被覆材料の使用量を節約し、それにより製造コストの低減を図ることができる。 The water-absorbing treatment material is configured to collapse when absorbing liquid. With such a configuration, the adhesive material in the coating layer portion spreads over a wide range, so that the agglomeration function can be efficiently exhibited. For this reason, even if it is a small amount of adhesive material, sufficient agglomeration function is exhibited. Therefore, even if the coating layer is made thinner than 1 mm, sufficient mass strength can be obtained. Therefore, it is possible to save the use amount of the coating material at the time of manufacturing, thereby reducing the manufacturing cost.
上記粒状芯部は、コーヒー豆、インスタントコーヒー又は茶葉の粉砕物を含有していてもよい。この場合、コーヒー豆、インスタントコーヒー又は茶葉の強力な消臭・脱臭効果により、使用済みの吸水処理材からの悪臭の放出を効果的に抑制することができる。 The granular core may contain coffee beans, instant coffee or tea leaf pulverized material. In this case, due to the strong deodorizing / deodorizing effect of coffee beans, instant coffee or tea leaves, it is possible to effectively suppress the release of malodor from the used water-absorbing treatment material.
上記粉砕物の粒度は、１ｍｍ未満であることが好ましい。この場合、液体の吸収時に崩壊し易い吸水処理材を実現することができる。 The particle size of the pulverized product is preferably less than 1 mm. In this case, it is possible to realize a water-absorbing treatment material that easily collapses during liquid absorption.
上記粒状芯部における上記粉砕物の含有率は、９０重量％以上であることが好ましい。この場合、コーヒー豆、インスタントコーヒー又は茶葉の含有率が高くなるため、特に優れた防臭効果を得ることができる。 The content of the pulverized product in the granular core is preferably 90% by weight or more. In this case, since the content of coffee beans, instant coffee or tea leaves is increased, a particularly excellent deodorizing effect can be obtained.
上記粒状芯部は、上記粉砕物と共に、水溶性又は水解性の材料を含有していてもよい。この場合、使用時に吸水処理材が崩壊するのを妨げることなく、吸水処理材に様々な機能をもたせることができる。 The granular core part may contain a water-soluble or water-decomposable material together with the pulverized product. In this case, the water absorption treatment material can have various functions without hindering the water absorption treatment material from collapsing during use.
上記粒状芯部における上記材料の含有率は、１０重量％以下であることが好ましい。この場合、コーヒー豆、インスタントコーヒー又は茶葉の含有率を高くすることが可能なため、特に優れた防臭効果を得ることができる。 The content of the material in the granular core is preferably 10% by weight or less. In this case, since the content of coffee beans, instant coffee or tea leaves can be increased, a particularly excellent deodorizing effect can be obtained.
上記材料は、澱粉類、ＣＭＣ、ＰＶＡ又は吸水性ポリマーであってもよい。これらの材料は、充分な水溶性又は水解性を有するので、使用時に吸水処理材が崩壊するのを妨げないという点で好ましい。 The material may be starches, CMC, PVA or a water-absorbing polymer. Since these materials have sufficient water-solubility or water-decomposability, they are preferable in that they do not prevent the water-absorbing treatment material from collapsing during use.

[Function and effect]
吸水処理材１は、尿等の液体を吸収した時に崩壊するように構成されている。かかる構成により、被覆層部２０中の接着性材料２２は、広範囲に行き渡るようになるため、効率良く塊状化機能を発揮することができる。このため、少量の接着性材料２２であっても、充分な塊状化機能が発揮される。それゆえ、被覆層部２０を１ｍｍ未満という薄さ（通常、被覆層部の厚みは１ｍｍ以上である）にしても、充分な固まり強度が得られる。したがって、製造時における被覆材料の使用量を節約し、それにより製造コストの低減を図ることができる。このように、使用後の固まり強度が高く、かつ低コストで製造することが可能な吸水処理材１が実現されている。 The water-absorbing treatment material 1 is configured to collapse when absorbing liquid such as urine. With this configuration, the adhesive material 22 in the covering layer portion 20 is spread over a wide range, and thus can efficiently perform the lump function. For this reason, even with a small amount of the adhesive material 22, a sufficient agglomeration function is exhibited. Therefore, even if the thickness of the coating layer portion 20 is less than 1 mm (usually, the thickness of the coating layer portion is 1 mm or more), sufficient mass strength can be obtained. Therefore, it is possible to save the use amount of the coating material at the time of manufacturing, thereby reducing the manufacturing cost. Thus, the water-absorbing treatment material 1 that has high mass strength after use and can be manufactured at low cost is realized.
また、被覆層部２０が１ｍｍ未満と薄いため、粒状芯部１０による吸水、ひいてはその崩壊が促進される。このように、吸水処理材１においては、その崩壊性が被覆層部２０の薄化を可能にする一方で、被覆層部２０の薄さが吸水処理材１の崩壊性を促進するという相互的作用により、製造コストの低減が実現されている。 Moreover, since the coating layer part 20 is as thin as less than 1 mm, the water absorption by the granular core part 10, and its collapse | decrease are accelerated | stimulated. Thus, in the water-absorbing treatment material 1, the disintegration property enables the coating layer portion 20 to be thinned, while the thinness of the coating layer portion 20 promotes the disintegration property of the water-absorbing treatment material 1. Due to the action, the manufacturing cost is reduced.
コーヒー豆、インスタントコーヒー又は茶葉の粉砕物を粒状芯部１０に含有させた場合、コーヒー豆、インスタントコーヒー又は茶葉の強力な消臭・脱臭効果により、使用済みの吸水処理材１からの悪臭（尿の臭い）の放出を効果的に抑制することができる。そのため、防臭効果の優れた吸水処理材１を実現することができる。 When the ground core portion 10 contains coffee beans, instant coffee or tea leaf pulverized product, the bad smell (urine) from the used water-absorbing treatment material 1 due to the strong deodorizing / deodorizing effect of the coffee beans, instant coffee or tea leaves. Odor) can be effectively suppressed. Therefore, the water-absorbing treatment material 1 having an excellent deodorizing effect can be realized.
粒状芯部１０における上記粉砕物の含有率を９０重量％以上とした場合、コーヒー豆、インスタントコーヒー又は茶葉の含有率が高くなるため、特に優れた防臭効果を得ることができる。 When the content of the pulverized product in the granular core 10 is 90% by weight or more, the content of coffee beans, instant coffee, or tea leaves is increased, so that a particularly excellent deodorizing effect can be obtained.
粒状芯部１０に含有される粉砕物の粒度を１ｍｍ未満とした場合、尿の吸収時に崩壊し易い吸水処理材１を実現することができる。 When the particle size of the pulverized product contained in the granular core 10 is less than 1 mm, it is possible to realize the water-absorbing treatment material 1 that easily disintegrates during urine absorption.
上記粉砕物と共に、水溶性又は水解性の材料を粒状芯部１０に含有させた場合、使用時に吸水処理材１が崩壊するのを妨げることなく、吸水処理材１に様々な機能をもたせることができる。 When the water-soluble or water-degradable material is contained in the granular core 10 together with the pulverized product, the water-absorbing treatment material 1 can have various functions without preventing the water-absorbing treatment material 1 from collapsing during use. it can.
粒状芯部１０における上記材料の含有率を１０重量％以下とした場合、コーヒー豆、インスタントコーヒー又は茶葉の含有率を高くすることが可能なため、特に優れた防臭効果を得ることができる。 When the content rate of the said material in the granular core part 10 shall be 10 weight% or less, since the content rate of coffee beans, instant coffee, or a tea leaf can be made high, the especially outstanding deodorizing effect can be acquired.
上記材料として、澱粉類、ＣＭＣ、ＰＶＡ又は吸水性ポリマーを用いた場合、これらの材料は、充分な水溶性又は水解性を有するので、使用時に吸水処理材１が崩壊するのを妨げないという点で好ましい。
［製造方法］
When starch, CMC, PVA or a water-absorbing polymer is used as the above material, these materials have sufficient water-solubility or water-decomposability, so that the water-absorbing treatment material 1 is not prevented from disintegrating during use. Is preferable.
[Production method]
吸水処理材１の製造方法の一例を説明する。この製造方法は、成形工程、被覆工程、分粒工程、及び乾燥工程を含んでいる。 An example of the manufacturing method of the water absorption processing material 1 is demonstrated. This manufacturing method includes a forming step, a covering step, a sizing step, and a drying step.
成形工程においては、芯部材料を破砕機で所定の大きさに粉砕し、当該粉砕された芯部材料を所定の割合でミキサーに投入して混ぜ合わせる。そして、加水した後、当該混合物をエクストルーダその他の押出成形機によって押出成形することにより、粒状芯部１０を形成する。 In the molding step, the core material is pulverized to a predetermined size with a crusher, and the pulverized core material is put into a mixer at a predetermined ratio and mixed. And after adding water, the granular core part 10 is formed by extruding the said mixture with an extruder other extruder.
被覆工程においては、コーティング装置等を用いて、粒状芯部１０の周囲に、接着性材料２２を含む被覆材料を散布又は噴霧することにより、被覆層部２０を形成する。このとき、被覆層部２０の厚みｄ１が１ｍｍ未満になるようにする。 In the coating step, the coating layer portion 20 is formed by spraying or spraying a coating material including the adhesive material 22 around the granular core portion 10 using a coating apparatus or the like. At this time, the thickness d1 of the covering layer portion 20 is set to be less than 1 mm.
分粒工程においては、所定の寸法の篩目を有する篩に、前工程で製造された吸水処理材を通過させることにより、所定の規格を満たす吸水処理材のみを抽出する。 In the sizing step, only the water-absorbing treatment material that satisfies a predetermined standard is extracted by passing the water-absorbing treatment material produced in the previous step through a sieve having a sieve with a predetermined size.
乾燥工程においては、前工程で抽出された吸水処理材を乾燥機で乾燥させる。粒状芯部１０の含水率が高過ぎると、吸水処理材１の保存時にカビ等が生じる原因となる。乾燥により、その含水率を適宜調整することにより、カビ等の発生を防ぐことができる。 In the drying step, the water-absorbing treatment material extracted in the previous step is dried with a dryer. If the water content of the granular core part 10 is too high, it will cause mold and the like during storage of the water-absorbing treatment material 1. Generation | occurrence | production of mold | fungi etc. can be prevented by adjusting the moisture content suitably by drying.
なお、乾燥工程の後に、香料添加工程を実行してもよい。この工程においては、吸水処理材１の袋詰めに用いられる包装袋内に、香料が入れられる。香料は、例えば、空気と共に包装袋内に噴射される。かかる空気の噴射は、包装袋を拡開するために行われるものである。この工程は、吸水処理材１を包装袋に詰める工程（袋詰め工程）よりも先に行われることが好ましい。 In addition, you may perform a fragrance | flavor addition process after a drying process. In this step, a fragrance is placed in a packaging bag used for bagging the water-absorbing treatment material 1. A fragrance | flavor is injected in a packaging bag with air, for example. Such air injection is performed in order to expand the packaging bag. This step is preferably performed prior to the step of filling the water-absorbing treatment material 1 in a packaging bag (bag filling step).
上記香料は包装袋内で吸水処理材１に付着するため、芳香性を有する吸水処理材１が得られる。このように包装袋内に香料を入れることにより、それよりも前の工程において製造装置に香料が付着するのを防ぐことができる。したがって、製造後の装置の清掃が容易になる。 Since the said fragrance | flavor adheres to the water absorption processing material 1 within a packaging bag, the water absorption processing material 1 which has aromaticity is obtained. Thus, by putting a fragrance | flavor in a packaging bag, it can prevent that a fragrance | flavor adheres to a manufacturing apparatus in the process before it. Therefore, cleaning of the apparatus after manufacture becomes easy.
香料が空気と共に包装袋内に噴射される場合、包装袋内に空気を噴射するための装置と別に、包装袋内に香料を入れるための装置を設ける必要がない。そのため、製造設備の複雑化を回避しつつ、芳香性を有する吸水処理材１を得ることができる。 When the fragrance is injected into the packaging bag together with air, it is not necessary to provide a device for putting the fragrance in the packaging bag, separately from the device for injecting air into the packaging bag. Therefore, the water-absorbing treatment material 1 having aromaticity can be obtained while avoiding the complexity of the production equipment.
香料添加工程が袋詰め工程よりも先に行われる場合、包装袋内の全体に香料が行き渡った状態で吸水処理材１を詰めることができる。そのため、包装袋内の複数の吸水処理材１に万遍なく香料を付着させ易くなる。 When the fragrance | flavor addition process is performed ahead of a bagging process, the water absorption processing material 1 can be stuffed in the state which the fragrance | flavor has spread throughout the packaging bag. Therefore, it becomes easy to attach a fragrance | flavor uniformly to the several water absorption processing material 1 in a packaging bag.
また、香料を包装袋内に噴射しているため、香料を包装袋の外で噴射する場合（例えば、包装袋に詰められる前の吸水処理材１に噴射する場合）に比べて、無駄になる香料の量を少なくすることができる。 Moreover, since the fragrance | flavor is injected in the packaging bag, it is useless compared with the case where the fragrance is injected outside the packaging bag (for example, when the water-absorbing treatment material 1 before being packed in the packaging bag is injected). The amount of fragrance can be reduced.
