Description
本発明は、使用済み紙おむつから回収した素材と木材の製材及び乾燥時に剥がれた樹皮を用い、ガーデニング用品・バイオマス燃料・建築資材・梱包資材として使用できるようにした吸水性軽量材に関する。 The present invention relates to a water-absorbing lightweight material that can be used as a gardening article, biomass fuel, building material, or packaging material using a material collected from used paper diapers, wood lumber, and bark peeled off during drying.
従来、使用済み紙おむつは焼却処理するか、又は埋め立て処分されていた。近年ではこれらに代わる処理方法として、使用済み紙おむつを水溶化して使用材料を分離回収し、回収素材を再利用するリサイクルシステムが確立されている(特許文献1参照)。回収したパルプのうち純度の高い上質パルプは紙おむつや紙製品のパルプとして再利用されている。 Conventionally, used paper diapers have been incinerated or disposed of in landfills. In recent years, as an alternative processing method, a recycling system has been established in which used paper diapers are made water-soluble, used materials are separated and recovered, and the recovered materials are reused (see Patent Document 1). Of the recovered pulp, high-quality pulp with high purity is reused as pulp for paper diapers and paper products.
ところで、前記回収素材のうち高分子吸収ポリマーや不純物を含む低質パルプはコンポスト(堆肥)等に利用されることもあるが、通常は処理費用を必要とする産業廃棄物として処理されるなど、単体での付加価値商品への転用が困難であった。また、林業の分野では木材の製材及び乾燥時に剥がれた樹皮を牛舎等の敷き藁の代用品やバイオマス燃料等に利用する研究が進められているが、現状では処理費用を必要とする産業廃棄物として取り扱われ、これも単体での付加価値商品への転用は困難であった。
本発明が解決しようとする課題は、従来のこれらの問題点を解消し、従来では産業廃棄物として処理されていた低質パルプと高分子吸収ポリマーと樹皮を組み合わせ、ガーデニング用品等として使用できるようにした吸水性軽量材を提供することにある。 The problem to be solved by the present invention is to solve these conventional problems and to combine low-quality pulp, polymer absorbent polymer, and bark, which were conventionally treated as industrial waste, so that it can be used as a gardening article or the like. It is in providing the water-absorbing lightweight material.

The configuration of the present invention that solves this problem is as follows.
1) A polymer-absorbing polymer recovered from a used paper diaper and a fibrous low-quality pulp containing impurities are mixed and stirred in water, and the fibers are entangled with each other by stirring to form a predetermined shape. in the compression molding, the water-absorbing lightweight material 2) was stirred and mixed together in water and fibrous low quality pulp containing ground bark polymeric absorbent polymer recovered from used disposable diapers and impurities, fibrous bark by stirring The water absorbing material according to any one of 1) to 2), wherein the water absorbent lightweight material 3) is compressed and molded into a predetermined shape after being entangled so as to be enveloped with low-quality pulp, and 3) carbonized after compression molding. Lightweight material 4) Plant cultivator with the water-absorbing lightweight material as described in any one of 1) to 3) as a main material 5) After heating wood in a drying chamber at a temperature of 75 ° C. or lower, the drying chamber is dehumidified under reduced pressure Collected sap, Alternatively ,
本発明によれば、従来では産業廃棄物として処理されていた低質パルプと高分子吸収ポリマーと樹皮を有効活用できる。また、繊維状パルプに水分を含んだ状態で圧縮するから、加熱を要することなく1t程度の低い圧縮力で常温成形でき、しかも攪拌で繊維同士が複雑に交絡して分離し難くなっているから、強く圧縮しなくても強固な成形品が得られる。 According to the present invention, low-quality pulp, polymer-absorbing polymer, and bark that have been conventionally treated as industrial waste can be effectively used. In addition, since the fibrous pulp is compressed in a state of containing moisture, it can be molded at room temperature with a compressive force as low as about 1 t without requiring heating, and the fibers are difficult to entangle and separate with stirring. A strong molded product can be obtained without strong compression.
本発明の繊維状低質パルプは使用済み紙おむつを水溶化してビニール類を除去したものから更に上質パルプを除いた低質パルプを使用する。高分子吸収ポリマーはこれらに含まれていたものに塩化カルシウム等のモノマー化剤を混合して屎尿等を脱水処理したものを使用する。樹皮を混合するものは繊維状低質パルプと樹皮の混合割合が20:80〜80:20の範囲が実用的であり、強度を必要とする場合は繊維状低質パルプの割合を多くして高い圧縮力で成形する。 Fibrous low quality pulp of the present invention is to use a low-quality pulp, excluding even the pressurized et al further fine pulp spent disposable diaper was removed by water-soluble vinyl compound. As the polymer-absorbing polymer, those obtained by mixing a monomeric agent such as calcium chloride with those contained therein and dehydrating urine and the like are used. For bark blends, the mixing ratio of fibrous low-quality pulp and bark is practically in the range of 20:80 to 80:20. When strength is required, the ratio of fibrous low-quality pulp is increased and high compression is achieved. Mold with force.
吸水性軽量材をガーデニングポット等の植物栽培器に用いる場合は、プレス材料に窒素・リン酸・カリウム等を含有する液肥を混合するか、その液肥を予め繊維状低質パルプと樹皮に含浸させた後に圧縮成形し、植栽や播種後に必要な養分を供給できるようにしてもよい。また、植物の樹液を混合するとその樹液に含まれる各種成分で抗菌・防虫・防カビ性能を付与でき、芳香成分が含まれるものは芳香を付与できる。抗菌・防虫・防カビ成分を有する樹液としては、杉・桧・赤松・ヒバ・ケヤキ・クス・米松・メイプル・ラジアータパインなどから抽出したものが使用でき、芳香成分を有する樹液としては、桧・モミなどから抽出したものが使用できる。樹液は、木材を75℃以下(望ましくは65℃以下)の温度の乾燥室内で加熱した後に乾燥室内を減圧除湿して採取したものを用いる。75℃以上では樹液の成分が分解されて効果が低下する。この樹液の採取に用いる乾燥機は、特許第3881643号公報記載の技術や特許第3906313号公報記載の技術を利用する。既存の木材乾燥機では100℃以上の高熱が加えられるため利用できない。以下、本発明の各実施例を図面に基づいて具体的に説明する。 When using a water-absorbing lightweight material for a plant growing device such as a gardening pot, liquid fertilizer containing nitrogen, phosphoric acid, potassium, etc. is mixed in the press material, or the liquid fertilizer is impregnated in advance with fibrous low-quality pulp and bark. It may be compression-molded later so that necessary nutrients can be supplied after planting and sowing. Moreover, when plant sap is mixed, various components contained in the sap can impart antibacterial, insect-proof, and fungicidal performances, and those containing aroma components can impart aroma. As sap having antibacterial, insecticidal, and fungicidal components, those extracted from cedar, camellia, red pine, hiba, zelkova, cous, rice pine, maple, radiata pine, etc. can be used. The one extracted from fir can be used. The sap is obtained by heating wood in a drying chamber having a temperature of 75 ° C. or lower (preferably 65 ° C. or lower) and then dehumidifying the drying chamber under reduced pressure. Above 75 ° C, the sap components are decomposed and the effect is reduced. The dryer used for collecting the sap uses the technology described in Japanese Patent No. 3881643 and the technology described in Japanese Patent No. 3906313. Existing wood dryers cannot be used because high heat of 100 ° C. or higher is applied. Embodiments of the present invention will be specifically described below with reference to the drawings.
