Description

本発明は、ゴムからなる環境燃料（ｅｎｖｉｒｏｎｍｅｎｔａｌ ｆｕｅｌ）及びその製造方法に関し、特に、廃ゴム材を経済性が高い環境燃料に変換するゴムからなる環境燃料及びその製造方法に関する。   BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an environmental fuel made of rubber and a method for producing the same, and more particularly, to an environmental fuel made of rubber for converting waste rubber material into an environmental fuel having high economical efficiency and a method for producing the same.

廃棄物は一般廃棄物と産業廃棄物の２種類に分けられる。廃棄物が大量に積み上げられて土地が占拠されることを防ぐために、廃棄物は一般に焼却されるか埋め立てられていた。そのため、その他の処理を行って廃棄物を再利用可能な物質に変換させることができる場合、環境保護の理念に沿い、経済発展を促進させることができる。   Waste is divided into two types: general waste and industrial waste. Waste was generally incinerated or landfilled to prevent large amounts of waste from occupying the land. Therefore, if the waste can be converted into a reusable substance by performing other treatment, economic development can be promoted in line with the idea of environmental protection.

本発明者は、環境保護に強い関心があり、廃プラスチック容器の再利用について研究を行っており、特許文献１の環境燃料及びその製造方法において、廃プラスチックにより環境燃料を製造する技術を開発し、特許権が付与されている。   The present inventor has a strong interest in environmental protection and is conducting research on the reuse of waste plastic containers. In the environmental fuel and its manufacturing method of Patent Document 1, a technique for producing environmental fuel from waste plastic has been developed. , A patent right is granted.

本発明者は廃ゴム材の再利用について研究を行い、その廃ゴム材は、主にタイヤ製造業から供給され、次に多い供給元はゴム工場であり、ゴム工場の製造工程で発生する廃ゴム、不良品、端材や自動車の使用済み廃タイヤなどが含まれる。   The present inventor has conducted research on the reuse of waste rubber materials, and the waste rubber materials are mainly supplied from the tire manufacturing industry, and the second largest supplier is a rubber factory, and the waste generated in the manufacturing process of the rubber factory. It includes rubber, defective products, scraps and used tires of automobiles.

タイヤは消耗品であり、全世界で毎年、数千万台又は数千万台以上の様々な自動車が走行しているため、毎年、大量の廃タイヤが発生し、これら廃タイヤは、汚染源の一つとなっている。
一般にタイヤは、組成が複雑であり、天然ゴム、合成ゴム、ブラックカーボン、ナイロン巻線、ワイヤ、イオウ、石油、樹脂などを含み、製造過程で混合して高温成形されると、一般に変質して元の材料に戻ることはない。また、廃タイヤは、発熱量が大きいため（１キロ当たり３７００万ジュール）、切断加工し、セメントキルン、発電所、製紙工場の燃料として使用されることがあるが、排出される排気ガスには、発がん性物質を含むダイオキシン及び酸窒化物などの浮遊粒子及び悪臭の空気汚染物質が含まれ、スラグにも大量の灰が含まれることがあり、資源全体の利用効率は理想的でなかった。 Tires are consumables, and tens of millions of vehicles or tens of millions of different vehicles are driving the world every year, so a large amount of waste tires are generated every year. It is one.
Generally, a tire has a complicated composition, and contains natural rubber, synthetic rubber, black carbon, nylon winding, wire, sulfur, petroleum, resin, etc. There is no return to the original material. Also, since waste tires generate a large amount of heat (37 million joules per kilometer), they may be cut and used as fuel for cement kilns, power plants, and paper mills, but the exhaust gas emitted is , Airborne pollutants such as dioxin and oxynitride containing carcinogens and malodorous air pollutants are contained, and slag may contain a large amount of ash, so the utilization efficiency of the entire resource was not ideal.

また、廃タイヤ、プラスチック、ゴムを解砕方式で処理して原料を採取し、解砕工程の際、カーボンブラックも発生するが、カーボンブラックを再利用する方法はまだ開発されていなかった。カーボンブラックにはカーボンが含まれ、メーカーは発生したカーボンブラックを他の工場へ販売して石炭として使用するが、解砕処理作業のコストが高いため、単純な量り売りの場合、カーボンブラックを生産するメーカーにとっては割に合わなかった。   Further, although carbon black is also generated during the crushing process by collecting raw materials by treating waste tires, plastics, and rubber by a crushing method, a method for reusing carbon black has not yet been developed. Carbon black contains carbon, and the manufacturer sells the generated carbon black to other factories and uses it as coal. However, because the cost of the crushing process is high, carbon black is produced if it is sold by simple measure. It didn't pay for the manufacturer.

本発明の技術手段、目的及びそれにより達成可能な効果を、より完全かつ明白に開示するために、開示した添付の図面及び符号と併せて本発明を以下に詳説する。   In order to more completely and clearly disclose the technical means, objects and effects achievable by the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and reference signs disclosed.

まず、図１を参照する。図１に示すように、本発明の一実施形態に係るゴムからなる環境燃料及びその製造方法は、廃棄のゴム材１を使用する。
ゴム材１を粉砕して細かく砕いた後、特定割合の除害物質２を添加して十分に混合し、除害物質２により化学反応を起こしてゴム材１中の有害な塩素、イオウ物質を除去し、燃焼可能で無害な環境燃料３を得る。 First, referring to FIG. As shown in FIG. 1, an environmental fuel made of rubber and a method for manufacturing the same according to one embodiment of the present invention uses a discarded rubber material 1.
After the rubber material 1 is crushed and finely pulverized, a specific ratio of the harmful substance 2 is added and mixed sufficiently, and a chemical reaction is caused by the harmful substance 2 to remove harmful chlorine and sulfur substances in the rubber substance 1. It is removed to obtain a combustible and harmless environmental fuel 3.

一般にゴム材は、発熱量が高すぎて、約７９００ｋｃａｌ／ｋｇを超えるとボイラを損壊させて有害な塩素ガスを発生させることがある。ゴム材１中に一定割合の除害物質２を加える。除害物質２には、ノンハロゲン系難燃剤（ｈａｌｏｇｅｎ−ｆｒｅｅ ｆｌａｍｅ ｒｅｔａｒｄａｎｔ）２１及び脱硫剤２２が含まれる。
ノンハロゲン系難燃剤２１（難燃剤）を加えると、ゴム材１を燃焼させたときの外部の気体との結合が減り、発熱量を約６０００〜６８００ｋｃａｌ／ｋｇに制御することができ、有害な塩素ガスの発生を減らすことができる。脱硫剤２２を加えると、主に廃ゴム分子中のイオウは、化学反応方式で抽出され、別の物質により捕捉して沈殿し、不燃、無汚染の物質に成形され、ゴム材１を燃焼しても硫黄酸化物は放出されず、優れて無害な環境燃料が成形される。
以下、脱硫剤の実施例について説明する。 Generally, a rubber material has a too high calorific value, and when it exceeds about 7900 kcal / kg, it may damage the boiler and generate harmful chlorine gas. A certain proportion of the harmful substance 2 is added to the rubber material 1. The detoxifying substance 2 includes a halogen-free flame retardant 21 and a desulfurizing agent 22.
When the non-halogen flame retardant 21 (flame retardant) is added, the bond with the external gas when the rubber material 1 is burned is reduced, and the calorific value can be controlled to about 6000 to 6800 kcal / kg, which is harmful chlorine. Gas generation can be reduced. When the desulfurizing agent 22 is added, the sulfur in the waste rubber molecule is mainly extracted by a chemical reaction method, trapped by another substance and precipitated, and is molded into a non-combustible and non-polluting substance to burn the rubber material 1. However, no sulfur oxide is released, and an excellent and harmless environmental fuel is molded.
Hereinafter, examples of the desulfurizing agent will be described.

（実施例）
ベンゾキノン（１、４−Ｂｅｎｚｏｑｕｉｎｏｎｅ）と安息香酸（Ｂｅｎｚｏｉｃ ａｃｉｄ）との反応によりフェニル基（ｐｈｅｎｙｌ ｒａｄｉｃａｌ）を発生させ、フェニル基の反応によりゴム分子中のイオウを捕捉してから、ＣａＯ、ＣａＣＯ３、ＣａＣなどのカルシウム系物質によりイオウＳ分子を捕捉し、無害で不燃のＣａＳ、ＣａＳＯ４などの沈殿物を形成する。 (Example)
A phenyl group is generated by the reaction of benzoquinone (1,4-Benzoquinone) and benzoic acid (Benzoic acid), and sulfur in the rubber molecule is captured by the reaction of the phenyl group, and then CaO, CaCO 3 , Sulfur S molecules are captured by a calcium-based substance such as CaC, and a harmless and incombustible precipitate such as CaS or CaSO 4 is formed.

ここで難燃剤とは、燃料の可燃性を下げるか燃焼を遅らせる物質のことであり、例えば、交通、電子、電気機器、家具建材など、日常生活に利用され、既に長い歴史があり、一部の難燃剤は、特定の用途には非常に適するが、他の分野には適しない。すなわち、どの難燃剤にも万能な物はなく、応用分野毎に異なる手段を選択する必要がある。本発明は、ノンハロゲン系の難燃剤を利用し、プラスチック材料類の製品に適用し、燃焼する際、揮発せずに腐食性ガスも発生させない、無公害型の難燃剤である。   Here, the flame retardant is a substance that lowers the flammability of fuel or delays combustion.For example, it is used in daily life such as transportation, electronics, electrical equipment, furniture building materials, etc. Flame retardants are very suitable for certain applications, but not for other fields. That is, there is no universal flame retardant, and it is necessary to select different means for each application field. INDUSTRIAL APPLICABILITY The present invention is a pollution-free flame retardant that uses a non-halogen flame retardant, is applied to products made of plastic materials, and does not generate a corrosive gas without volatilizing when burned.

しかし、ノンハロゲン系難燃剤２１の添加割合が高すぎる場合、ゴム材１を燃焼することができないため、添加割合を適宜調整する必要がある。
本発明では実験により最適な添加割合を得た。その除害物質２をゴム材１中に添加する量は、重量％で５〜３５％である。ノンハロゲン系難燃剤２１と脱硫剤２２との割合は、ノンハロゲン系難燃剤２１：３０〜５０％、脱硫剤２２：５０〜７０％に制御される。ゴム材１に対して、ノンハロゲン系難燃剤２１の特定割合は、重量％で１．５〜１７．５％である。脱硫剤２２の特定割合は、重量％で２．５〜２４．５％である。 However, if the addition ratio of the non-halogen flame retardant 21 is too high, the rubber material 1 cannot be burned, so that the addition ratio needs to be adjusted appropriately.
In the present invention, the optimum addition ratio was obtained by experiments. The amount of the harmful substance 2 added to the rubber material 1 is 5 to 35% by weight. The proportions of the non-halogen flame retardant 21 and the desulfurization agent 22 are controlled to 21:30 to 50% of the non-halogen flame retardant and 22:50 to 70% of the desulfurization agent. The specific ratio of the halogen-free flame retardant 21 to the rubber material 1 is 1.5 to 17.5% by weight. The specific ratio of the desulfurizing agent 22 is 2.5 to 24.5% by weight.

上述した環境燃料は、加熱・加圧されて固体型の環境燃料に成形される。ゴム同士の粘着性が好ましくない場合、砕いたゴム材料中に除害物質を添加し、重量％で２〜６％の粘着剤（この粘着剤には水性樹脂が用いられる）を添加した後、加熱・加圧して型締し、無害燃焼の固体型環境燃料を得る。   The above-mentioned environmental fuel is heated and pressurized to be molded into a solid type environmental fuel. When the tackiness of the rubbers is not preferable, after adding the detoxifying substance to the crushed rubber material and adding 2 to 6% by weight of the adhesive (aqueous resin is used for this adhesive), Heat and pressurize the mold to obtain a harmless solid environmental fuel.

しかし、図２〜図５に示すように、上述した環境燃料は、好適な実施形態で本発明の環境燃料の製造方法について以下のステップ（ａ）〜（ｅ）により説明する。   However, as shown in FIGS. 2 to 5, the environmental fuel described above will be described in a preferred embodiment by the following steps (a) to (e) regarding the method for producing the environmental fuel of the present invention.

本発明の一実施形態に係る環境燃料の製造方法は、以下のステップを含む。
（ａ）粉砕：ゴム材１を粉砕装置により粉砕するステップ
（ｂ）混合：粉砕したゴム材１を攪拌装置に投入し、一定割合の除害物質２を添加し、除害物質２がノンハロゲン系難燃剤２１と脱硫剤２２とから構成され、攪拌装置で十分に混合して混合物を得るステップ
（ｃ）型締：混合物を型締装置内に投入し、加熱・圧縮して型締し、成形物を得るステップ

(A) Pulverization: Step of pulverizing rubber material 1 with a pulverizer (b) Mixing: The pulverized rubber material 1 is put into a stirrer, a certain proportion of the harmful substance 2 is added, and the harmful substance 2 is a non-halogen type Step (c) Mold clamping: Composed of flame retardant 21 and desulfurization agent 22 and thoroughly mixed with a stirrer to obtain a mixture: The mixture is put into a mold clamping device, heated and compressed to clamp, and molded. Step (d) Injection: Injection of the above-mentioned molded product into the granulating apparatus and heating to injection-mold the environmental fuel 3 (e) Cutting: Step of cutting the above-mentioned environmental fuel 3

図２を参照する。図２に示すように、（ａ）粉砕ステップは、廃棄回収のゴム材１を粉砕装置（例えば、ダイサー、粉砕機など）に投入して粉砕処理を行うが、その最適な粉砕状態を微細粉粒にした後、粉砕したゴム材１を攪拌装置中へ投入して（ｂ）混合ステップを行うとともに、攪拌装置中で特定割合の除害物質２をゴム材１へ添加する。
除害物質２は、ゴム材１中に重量％で５〜３５％添加される。ノンハロゲン系難燃剤２１と脱硫剤２２との割合は、ノンハロゲン系難燃剤２１：３０〜５０％、脱硫剤２２：５０〜７０％であり、ゴム材１にとって、ノンハロゲン系難燃剤２１の特定割合は、重量％で１．５〜１７．５％であり、脱硫剤２２の特定割合は、重量％で２．５〜２４．５％である。攪拌装置により十分に混合して混合物を得る。上述した攪拌装置には、球型の混合装置などが用いられてもよい。しかし、得られた混合物は粉状の環境燃料３でもよい。 Please refer to FIG. As shown in FIG. 2, in the (a) crushing step, the waste rubber material 1 is thrown into a crushing device (for example, a dicer, a crusher, etc.) to perform a crushing process. After granulating, the crushed rubber material 1 is put into a stirrer to perform the mixing step (b), and a specific ratio of the harmful substance 2 is added to the rubber material 1 in the stirrer.
The harmful substance 2 is added to the rubber material 1 in an amount of 5 to 35% by weight. The non-halogen flame retardant 21 and the desulfurization agent 22 have a ratio of the non-halogen flame retardant 21:30 to 50% and the desulfurization agent 22:50 to 70%. For the rubber material 1, the specific ratio of the non-halogen flame retardant 21 is % By weight of 1.5 to 17.5%, and the specific ratio of the desulfurizing agent 22 is 2.5 to 24.5% by weight. Mix well with a stirrer to obtain a mixture. A spherical mixing device or the like may be used as the above-mentioned stirring device. However, the obtained mixture may be powdered environmental fuel 3.

固体型の環境燃料３が必要な場合、混合物を二本ロール、練り機などの型締装置で加熱・圧縮して成形し、（ｃ）型締ステップを行い、高密度の成形物を得る。続いて、（ｄ）射出ステップを行い、上述した成形物を造粒装置（造粒機）に投入して加熱射出させる。そのため、様々な形状（例えば、球状、棒状、ブロック状、プレート状、粒状など）の環境燃料３が得られる（図３〜図５に示す）。また、上述した環境燃料３は、必要な長さに応じて（ｅ）切断ステップを行い、環境燃料３を燃焼に適した長さに切断する。   When the solid type environmental fuel 3 is required, the mixture is heated and compressed by a mold clamping device such as a two-roll or kneader to be molded, and (c) the mold clamping step is performed to obtain a high density molded product. Subsequently, (d) an injection step is performed, and the above-mentioned molded product is put into a granulating device (granulator) and heated and injected. Therefore, the environmental fuel 3 having various shapes (for example, spherical, rod-shaped, block-shaped, plate-shaped, and granular) is obtained (shown in FIGS. 3 to 5). Further, the environmental fuel 3 described above is subjected to (e) cutting step according to the required length, and cuts the environmental fuel 3 into a length suitable for combustion.

混合した成形物の密度を高めるために、定型効果が好ましい環境燃料３を射出し、（ｄ）射出ステップにおいて成形物を造粒装置に投入する際、特定割合の接着剤も一緒に投入し、接着剤を成形物に混入させ、加熱して環境燃料を射出する。上述した接着剤の特定割合は、重量％で２〜６％であり、上述した接着剤には水性樹脂が用いられるため完全に成形され、バラバラになることがない。   In order to increase the density of the mixed molded product, the environmental fuel 3 having a preferable standard effect is injected, and when the molded product is charged into the granulating device in the (d) injection step, a specific proportion of the adhesive is also charged together, The adhesive is mixed in the molded product and heated to inject the environmental fuel. The specific ratio of the above-mentioned adhesive is 2 to 6% by weight, and since the above-mentioned adhesive uses an aqueous resin, it is completely molded and does not fall apart.

上述したことから分かるように、本発明のゴムからなる環境燃料及びその製造方法は、以下（１）〜（４）の長所を有する。
（１）ゴム材にノンハロゲン系難燃剤を加えることにより、燃焼する際、有毒塩素ガス及び有毒塩素物質が発生することを抑えることができる
