Description

エラストマー組成物およびその製造方法並びに該エラストマー組成物を用いたタイヤELASTOMER COMPOSITION, PROCESS FOR PRODUCING THE SAME, AND TIRE USING THE ELASTOMER COMPOSITION
　本発明は、エラストマー成分の使用量を低減したエラストマー組成物および該エラストマー組成物の製造方法、並びに該エラストマー組成物を使用したタイヤに関するものである。 The present invention relates to an elastomer composition in which the amount of an elastomer component used is reduced, a method for producing the elastomer composition, and a tire using the elastomer composition.
　タイヤ等に使用するエラストマー組成物は多量のエラストマー成分（ゴム等）を原料として含んでおり、例えば乗用車用空気入りタイヤの場合、エラストマー組成物の５０質量％以上が天然ゴムと合成ゴムとを配合したゴム成分からなる。従って、これらのエラストマー組成物および当該エラストマー組成物を使用したタイヤは、原油価格の高騰や天候不良によるゴムの不作等の影響を受け、原料コストが上昇したり、安定した製品の供給が困難となったりする恐れがある。 Elastomer compositions used for tires, etc. contain a large amount of elastomer components (rubber etc.) as raw materials. For example, in the case of pneumatic tires for passenger cars, 50% by mass or more of the elastomer composition contains natural rubber and synthetic rubber. Made of rubber components. Therefore, these elastomer compositions and tires using the elastomer compositions are affected by rising crude oil prices, rubber failure due to bad weather, etc., resulting in increased raw material costs and a difficult supply of stable products. There is a risk of becoming.
　また、近年では世界的に環境問題が重視される傾向にあり、特に地球温暖化防止の観点からＣＯ２の排出量の規制が強化され、石油資源の使用量の低減が求められていると共に、資源循環型社会の形成が求められている。 Moreover, in recent years, environmental problems tend to be emphasized globally. In particular, from the viewpoint of preventing global warming, regulations on CO 2 emissions have been strengthened, and reductions in the use of petroleum resources have been demanded. The formation of a resource recycling society is required.
　そこで、タイヤ製造時の石油資源の使用量を低減するため、例えば特許文献１には、全重量の７５重量％以上を石油外資源からなる原材料で構成した、いわゆるエコタイヤが記載されている。 Therefore, in order to reduce the amount of petroleum resources used when manufacturing tires, for example, Patent Document 1 describes a so-called eco-tire in which 75% by weight or more of the total weight is composed of raw materials made of resources other than petroleum.
特開２００３－６３２０６号公報JP 2003-63206 A
　しかし、上記従来技術にかかるエラストマー組成物およびタイヤでは、石油資源の使用量は低減できるものの、製造工程が複雑になったり、石油資源の代替原料の単価が高かったりするため、必ずしも製造コストを低減できなかった。 However, although the elastomer composition and tire according to the above prior art can reduce the amount of petroleum resources used, the manufacturing process becomes complicated and the unit price of alternative raw materials for petroleum resources is high, so the manufacturing cost is not necessarily reduced. could not.
　また、天然繊維等を代替原料として使用した場合には、代替原料自体に燃料・資源等としての利用可能性の余地があるという観点等から、代替原料に改良および選択の余地があった。 In addition, when natural fiber or the like is used as an alternative raw material, there is room for improvement and selection of the alternative raw material from the viewpoint that the alternative raw material itself has room for use as a fuel / resource.
　更に、配合する代替原料としては、エラストマー成分への分散性が良好で、ゴム等の代わりに配合してもエラストマー組成物の物性を大幅に低下させることが無いものが求められていた。また、そのような代替原料を用いたエラストマー組成物の製造方法も求められていた。 Furthermore, as an alternative raw material to be blended, a material that has good dispersibility in the elastomer component and does not significantly reduce the physical properties of the elastomer composition even when blended in place of rubber or the like has been demanded. Moreover, the manufacturing method of the elastomer composition using such an alternative raw material was also calculated | required.
　この発明は、上記課題を有利に解決することを目的とするものであり、本発明のエラストマー組成物は、エラストマー成分に対して有機物の発酵処理において生じる残滓を配合したエラストマー組成物であって、前記残滓には、該残滓の主成分以外の成分が６質量％以下の割合で含まれていることを特徴とする。
　このように、有機物の発酵処理において生じる残滓等の、資源を利用した後に残る残滓を配合すれば、エラストマー組成物中のエラストマー成分の使用量を低減することができる。また、有機物の発酵処理において生じる残滓は安価な残物であるから、代替原料として適している。よって、該残滓をエラストマー成分に配合することで、安価且つ環境負荷の低いエラストマー組成物を提供することができる。更に、発酵処理後の残滓は、発酵処理の過程で腐敗要因、例えば蛋白質や脂質の大部分が分解されているので扱い易いという利点も有している。なお、有機物の発酵とは、微生物の働きで有機物を分解することを意味し、嫌気的発酵および好気的発酵の双方を含む概念である。
　また、配合する残滓に含まれている主成分以外の成分の量が６質量％以下であれば、エラストマー成分に配合する際に残滓が凝集することが無く、エラストマー組成物中で残滓が良好に分散するので、代替原料を使用しないエラストマー組成物と比較して破断伸び等の物性が大幅に低下することが無いエラストマー組成物を提供することができる。ここで、「残滓の主成分」とは、残滓を構成する主な成分を意味し、例えば発酵処理に用いられた発酵菌の細胞壁、若しくは発酵処理で分解されずに残った植物の細胞壁、またはそれらの混合物、並びに水分が残滓の主成分となり得る。また、「主成分以外の成分が６質量％以下」とは、主成分以外の成分の総量が６質量％以下であることを指す。そして、主成分以外の成分の量は、例えば、糖類およびクエン酸などの有機酸についてはＨＰＬＣ（ハイ・パフォーマンス・リキッド・クロマトグラフィー、日本分光（株）製）を用いて、蛋白質についてはケルダール分析装置（ゲルハルトジャパン製）を用いて、脂質についてはソックスレイ脂質抽出器を用いて、カリウム等のイオンについてはホリバコンパクトイオンメーターを用いて測定することができる。 The present invention aims to advantageously solve the above-mentioned problems, and the elastomer composition of the present invention is an elastomer composition in which a residue generated in an organic material fermentation treatment is blended with an elastomer component, The residue contains a component other than the main component of the residue at a ratio of 6% by mass or less.
Thus, if the residue which remains after utilizing resources, such as the residue which arises in the fermentation process of organic substance, is mix | blended, the usage-amount of the elastomer component in an elastomer composition can be reduced. Moreover, since the residue produced in the fermentation process of organic matter is an inexpensive residue, it is suitable as an alternative raw material. Therefore, an elastomer composition with low cost and low environmental load can be provided by blending the residue into the elastomer component. Furthermore, the residue after the fermentation treatment also has an advantage that it is easy to handle because most of the decay factors such as proteins and lipids are decomposed during the fermentation treatment. The fermentation of organic matter means that the organic matter is decomposed by the action of microorganisms, and is a concept including both anaerobic fermentation and aerobic fermentation.
Moreover, if the amount of components other than the main component contained in the blended residue is 6% by mass or less, the residue does not aggregate when blended with the elastomer component, and the residue is excellent in the elastomer composition. Since it is dispersed, it is possible to provide an elastomer composition in which physical properties such as elongation at break are not significantly reduced as compared with an elastomer composition that does not use an alternative raw material. Here, the “main component of the residue” means a main component constituting the residue, for example, the cell wall of the fermenting bacteria used in the fermentation treatment, or the cell wall of the plant left undegraded by the fermentation treatment, or Their mixture, as well as moisture, can be the main component of the residue. Further, “the component other than the main component is 6 mass% or less” means that the total amount of the components other than the main component is 6 mass% or less. The amount of components other than the main components is, for example, HPLC (High Performance Liquid Chromatography, manufactured by JASCO Corporation) for organic acids such as sugars and citric acid, and Kjeldahl analysis for proteins. Using an apparatus (manufactured by Gerhard Japan), lipids can be measured using a Soxley lipid extractor, and ions such as potassium can be measured using a Horiba compact ion meter.
　また、本発明のエラストマー組成物は、エラストマー成分に対して有機物の発酵処理において生じる残滓を配合したエラストマー組成物であって、前記残滓に含まれている糖類、クエン酸およびアミノ酸の総量が、当該残滓の６質量％以下であることを特徴とする。このように、有機物の発酵処理において生じる残滓等の、資源を利用した後に残る残滓を配合すれば、上述した通り、安価且つ環境負荷の低いエラストマー組成物を提供することができる。また、エラストマー成分への配合時に残滓を凝集させる原因成分となる糖類、クエン酸およびアミノ酸の含有量を、残滓の６質量％以下とすれば、エラストマー成分に配合する際に残滓が凝集することが無く、エラストマー組成物中で残滓が良好に分散するので、代替原料を使用しないエラストマー組成物と比較して破断伸び等の物性が大幅に低下することが無いエラストマー組成物を提供することができる。ここで、「糖類」とは、糖質ともいい、単糖類や、単糖類が複数個縮合した小糖類または多糖類を意味し、ポリアルコールのアルデヒド、ケトン、酸、更にポリアルコール自身や、それらの誘導体、縮合体も含むものである。そして、残滓中の糖類、クエン酸およびアミノ酸の総量は、例えば、ＨＰＬＣ（ハイ・パフォーマンス・リキッド・クロマトグラフィー）を用いて測定することができる。 Further, the elastomer composition of the present invention is an elastomer composition in which a residue generated in the fermentation treatment of organic matter is blended with the elastomer component, and the total amount of saccharides, citric acid and amino acids contained in the residue is It is characterized by being 6% by mass or less of the residue. Thus, if the residue which remains after using resources, such as the residue which arises in the fermentation process of organic substance, is mix | blended, as mentioned above, an elastomer composition with low cost and low environmental impact can be provided. Moreover, if the content of saccharides, citric acid and amino acids, which are causative components for aggregating the residue when blended into the elastomer component, is 6% by mass or less of the residue, the residue may aggregate when blended into the elastomer component. In addition, since the residue is well dispersed in the elastomer composition, it is possible to provide an elastomer composition in which physical properties such as elongation at break are not significantly reduced as compared with an elastomer composition not using an alternative raw material. Here, the term “saccharide” is also referred to as a saccharide, and means a monosaccharide, a small saccharide or a polysaccharide obtained by condensing a plurality of monosaccharides, an aldehyde of a polyalcohol, a ketone, an acid, a polyalcohol itself, or those These derivatives and condensates are also included. The total amount of saccharides, citric acid and amino acids in the residue can be measured using, for example, HPLC (High Performance Liquid Chromatography).
　ここで、本発明のエラストマー組成物は、前記残滓に含まれている糖類の量が、当該残滓の４質量％以下であることが好ましい。糖類は残滓を凝集させ易い成分であるところ、残滓中の糖類量を残滓の４質量％以下とすることにより、エラストマー成分に配合する際に残滓が凝集せずにエラストマー組成物中で良好に分散するので、代替原料を使用しないエラストマー組成物と比較して破断伸び等の物性が大幅に低下することが無いエラストマー組成物を提供することができる。 Here, in the elastomer composition of the present invention, the amount of saccharide contained in the residue is preferably 4% by mass or less of the residue. Saccharide is a component that easily aggregates the residue. By making the amount of saccharide in the residue 4% by mass or less of the residue, the residue does not aggregate when blended into the elastomer component, and is well dispersed in the elastomer composition. Therefore, it is possible to provide an elastomer composition in which physical properties such as elongation at break are not significantly reduced as compared with an elastomer composition that does not use an alternative raw material.
　なお、本発明のエラストマー組成物は、エラストマー成分がゴム成分または樹脂であることが好ましい。 In the elastomer composition of the present invention, the elastomer component is preferably a rubber component or a resin.
　また、本発明のエラストマー組成物の製造方法は、エラストマー成分に対して有機物の発酵処理において生じる残滓を配合してエラストマー組成物を製造する方法であって、有機物の発酵処理後の残滓に含まれている糖類を、当該残滓に含まれる糖類の量が残滓の４質量％以下となるまで除去する糖類除去工程と、糖類を除去した前記残滓をエラストマー成分に配合して混練する混練工程とを含むことを特徴とする。糖類は残滓を凝集させ易い成分であるところ、このような製造方法によれば、生物分解や化学分解による糖類の分解、或いは、イオン交換、吸着、遠心分離などを利用して残滓中の糖類を除去した上で残滓をエラストマー成分に配合することができるので、代替原料を使用しないエラストマー組成物と比較して破断伸び等の物性が大幅に低下することが無いエラストマー組成物を提供することができる。 Further, the method for producing an elastomer composition of the present invention is a method for producing an elastomer composition by blending a residue generated in an organic fermentation process with an elastomer component, and is included in the residue after the organic fermentation process. A saccharide removal step of removing the saccharides contained in the residue until the amount of the saccharide contained in the residue is 4% by mass or less of the residue, and a kneading step of kneading the residue from which the saccharide has been removed with an elastomer component. It is characterized by that. Saccharides are a component that easily aggregates residue. According to such a production method, saccharides in the residue are decomposed by biodegradation or chemical decomposition, or ion exchange, adsorption, or centrifugation. Since the residue can be blended with the elastomer component after being removed, an elastomer composition can be provided in which physical properties such as elongation at break are not significantly reduced compared to an elastomer composition that does not use an alternative raw material. .
　ここで、前記糖類除去工程は、遠心分離を用いて糖類を除去する工程であることが好ましい。糖類は残滓に含まれている水分中に溶解した状態で存在していることが多いところ、遠心分離を用いれば、容易に糖類を残滓から分離できるからである。 Here, the saccharide removal step is preferably a step of removing saccharides using centrifugation. This is because saccharides are often present in a dissolved state in the water contained in the residue, and therefore the saccharide can be easily separated from the residue by using centrifugation.
　また、本発明のエラストマー組成物の製造方法は、前記残滓を乾燥する乾燥工程を更に含むことが好ましい。残滓を乾燥してから配合すれば、エラストマー成分中での残滓の分散性が更に向上するからである。なお、残滓を乾燥してからエラストマー成分に配合する場合における残滓中の糖類の量とは、乾燥前の残滓中の糖類の量を指す。 The method for producing an elastomer composition of the present invention preferably further includes a drying step for drying the residue. This is because if the residue is blended after being dried, the dispersibility of the residue in the elastomer component is further improved. The amount of saccharide in the residue when the residue is dried and then blended into the elastomer component refers to the amount of saccharide in the residue before drying.
　ここで、前記乾燥工程での乾燥は、前記有機物の発酵処理後の残滓をろ過した際のろ液の沸点よりも高い温度で行うことが好ましい。有機物の発酵処理後の残滓を篩、フィルタープレス等のろ過装置でろ過した際のろ液の沸点よりも高い温度、好ましくは１３０～２５０℃の温度で残滓を乾燥することにより、所望の含水率の残滓を迅速に得て、エラストマー組成物の製造に要する時間を短縮することができるからである。 Here, the drying in the drying step is preferably performed at a temperature higher than the boiling point of the filtrate when the residue after the fermentation of the organic matter is filtered. By drying the residue at a temperature higher than the boiling point of the filtrate, preferably 130 to 250 ° C., when the residue after the fermentation treatment of the organic matter is filtered by a filtration device such as a sieve or a filter press, a desired moisture content is obtained. This is because it is possible to quickly obtain the residue and shorten the time required for producing the elastomer composition.
　また、本発明のタイヤは、少なくとも一部を、上記エラストマー組成物、或いは、上記製造方法で製造したエラストマー組成物で構成したことを特徴とする。従来のタイヤではゴム等のエラストマーのみで構成していた部分を、有機物の発酵処理において生じる残滓であって残滓を凝集させる所定の成分の含有量が一定以下のものを配合したエラストマー組成物で構成することにより、タイヤとしての性能を維持しつつエラストマー成分の使用量を低減して環境負荷を低減可能なタイヤを提供することができる。 Further, the tire of the present invention is characterized in that at least a part of the tire is composed of the elastomer composition or the elastomer composition produced by the production method. In conventional tires, the part composed only of an elastomer such as rubber is composed of an elastomer composition containing a certain amount of a predetermined component for agglomerating the residue, which is a residue generated in an organic fermentation process. By doing so, it is possible to provide a tire capable of reducing the environmental load by reducing the amount of the elastomer component used while maintaining the performance as a tire.
　本発明によれば、所定の代替原料をエラストマー成分に配合することにより、複雑な製造工程を用いることなく低コストで製造が可能で且つ環境に優しいエラストマー組成物を、代替原料を使用しないエラストマー組成物と比較して物性を大幅に低下させることなく提供することができる。また、当該エラストマー組成物の製造方法、並びに当該エラストマー組成物を用いた、製造時の環境負荷が低いタイヤを提供することができる。 According to the present invention, an elastomer composition that does not use an alternative raw material can be produced at low cost without using a complicated manufacturing process by blending a predetermined alternative raw material into the elastomer component. It can be provided without significantly reducing the physical properties as compared with the product. Moreover, the manufacturing method of the said elastomer composition and the tire with a low environmental load at the time of manufacture using the said elastomer composition can be provided.
本発明のタイヤの一例の断面図である。It is sectional drawing of an example of the tire of this invention.
　以下に、本発明のエラストマー組成物を詳細に説明する。本発明に従うエラストマー組成物の一態様は、エラストマー成分に、有機物の発酵処理において生じる残滓であって該残滓の主成分以外の成分のが６質量％以下の割合で含まれている残滓を配合して混練することで、エラストマー成分の使用量を低減したことを特徴とする。また、本発明に従うエラストマー組成物の別の態様は、エラストマー成分に、有機物の発酵処理において生じる残滓であって残滓中に含まれている糖類、クエン酸およびアミノ酸の総量が、当該残滓の６質量％以下である残滓を配合して混練することで、エラストマー成分の使用量を低減したことを特徴とする。 Hereinafter, the elastomer composition of the present invention will be described in detail. In one embodiment of the elastomer composition according to the present invention, the elastomer component is mixed with a residue that is produced in the fermentation treatment of organic matter and contains a component other than the main component of the residue in a proportion of 6% by mass or less. The amount of elastomer component used is reduced by kneading. In another aspect of the elastomer composition according to the present invention, the total amount of saccharides, citric acid and amino acids contained in the residue, which is a residue generated in the fermentation process of organic matter, is 6 mass of the residue. The amount of the elastomer component used is reduced by blending and kneading the residue that is not more than%.
　ここで、エラストマー成分は、天然ゴム、合成ゴム等のゴム成分、熱可塑性エラストマー、熱硬化性エラストマー等の樹脂、或いは、それらを混合したものからなり、合成ゴムとしては、具体的には、スチレン－ブタジエン共重合体ゴム（ＳＢＲ）、ポリブタジエンゴム（ＢＲ）、ポリイソプレンゴム（ＩＲ）、アクリロニトリル－ブタジエン共重合体ゴム（ＮＢＲ）、クロロプレンゴム（ＣＲ）、ブチルゴム（ＩＩＲ）等が挙げられる。また、熱可塑性エラストマーとしては、エチレン－メチルアクリレート共重合体、スチレン系エラストマー、ウレタン系エラストマー、ポリオレフィン系エラストマー等が、熱硬化性エラストマーとしては、フェノール系エラストマー、ウレア系エラストマー、メラミン系エラストマー、エポキシ系エラストマー等が挙げられる。なお、本発明のエラストマー組成物は、任意に、カーボンブラックおよびシリカ等の補強性充填剤や、アロマオイル等の軟化剤、加硫促進剤、加硫促進助剤、老化防止剤等の一般に添加される添加剤等を含んでも良い。 Here, the elastomer component is composed of a rubber component such as natural rubber or synthetic rubber, a resin such as a thermoplastic elastomer or a thermosetting elastomer, or a mixture thereof. Specifically, as the synthetic rubber, styrene -Butadiene copolymer rubber (SBR), polybutadiene rubber (BR), polyisoprene rubber (IR), acrylonitrile-butadiene copolymer rubber (NBR), chloroprene rubber (CR), butyl rubber (IIR) and the like. Thermoplastic elastomers include ethylene-methyl acrylate copolymers, styrene elastomers, urethane elastomers, and polyolefin elastomers. Thermosetting elastomers include phenol elastomers, urea elastomers, melamine elastomers, and epoxy. Based elastomers and the like. The elastomer composition of the present invention is optionally added to reinforcing fillers such as carbon black and silica, softeners such as aroma oil, vulcanization accelerators, vulcanization accelerators, anti-aging agents, etc. Additive may be included.
　発酵処理される有機物としては、例えば、紙、家畜***物、食品廃棄物、焼酎粕（芋、米、麦焼酎の粕）、建設発生木材、黒液、余剰汚泥（例えば、下水汚泥、屎尿汚泥、メタン発酵汚泥）、飲料成分の抽出残渣（茶殻やコーヒー粕など）等の廃棄物系バイオマスと、稲わら、麦わら、籾殻、林地残材（間伐材・被害木など）等の未利用バイオマスと、飼料作物、果実、穀物、根菜類、でんぷん系作物等の資源作物バイオマスとを含む、再生可能な生物由来の有機性資源であるバイオマスが挙げられる。このようなバイオマスを用いれば、エラストマー組成物製造時の環境負荷をより低減できる。なお、資源の有効活用および環境負荷の低減という観点から、廃棄物系バイオマスを有機物として用いることが好ましい。 Examples of organic substances to be fermented include paper, livestock waste, food waste, shochu (potato, rice, barley shochu), construction-generated wood, black liquor, excess sludge (eg, sewage sludge, manure sludge) , Methane fermentation sludge), waste-based biomass such as beverage component extraction residue (such as tea husk and coffee straw), and unused biomass such as rice straw, wheat straw, rice husk and forest land residue (thinned wood, damaged trees, etc.) And biomass that is organic resources derived from renewable organisms, including resource crop biomass such as feed crops, fruits, cereals, root vegetables, and starch crops. If such biomass is used, the environmental load at the time of elastomer composition manufacture can be reduced more. In addition, it is preferable to use waste biomass as organic matter from the viewpoint of effective utilization of resources and reduction of environmental burden.
　また、有機物の発酵処理方法としては、嫌気性微生物を用いた発酵処理として、例えばメタン生成菌を用いたメタン発酵、エタノール発酵菌を用いたエタノール発酵、水素生成菌を用いた水素発酵等があり、好気性微生物を用いた発酵処理として、例えば酢酸産生菌を用いた酢酸発酵、アンモニア酸化細菌等の各種酸化細菌を用いた排水処理等がある。ここで、好気性微生物を利用した好気性発酵処理は、残滓の臭気が少ないので、配合時の消臭処理が不要であるという点で発酵処理方法として好ましい。一方、メタン発酵処理、エタノール発酵処理、または水素発酵処理は、資源から効率的に燃料等を取り出した後の残滓を用いることができ、環境への負荷低減と共に資源の有効活用を図ることができるという点で発酵処理方法として好ましい。 Moreover, as a fermentation treatment method of organic matter, there are, for example, methane fermentation using methanogen, ethanol fermentation using ethanol fermenter, hydrogen fermentation using hydrogen producer, etc. Examples of fermentation treatment using aerobic microorganisms include acetic acid fermentation using acetic acid-producing bacteria, and wastewater treatment using various oxidizing bacteria such as ammonia oxidizing bacteria. Here, the aerobic fermentation treatment using aerobic microorganisms is preferable as a fermentation treatment method in that the deodorization treatment at the time of blending is unnecessary because the odor of the residue is small. On the other hand, in methane fermentation treatment, ethanol fermentation treatment, or hydrogen fermentation treatment, the residue after efficiently removing the fuel from the resources can be used, and the resources can be reduced and the resources can be effectively utilized. Therefore, it is preferable as a fermentation treatment method.
　なお、上述した通り、エラストマー成分に配合する残滓としては、例えば、好気または嫌気条件下で有機物の生物学的処理（発酵）を行った際に生じる余剰汚泥等を用いることができるが、余剰汚泥を残滓として用いる場合にはエラストマー組成物の軽量化および金属含有によるエラストマー組成物への悪影響防止という観点から、鉄系の凝集剤を含まない汚泥、例えばアルミ化合物を凝集剤として使用した汚泥が好ましく、凝集剤を含まない汚泥がより好ましい。 As described above, as the residue to be blended in the elastomer component, for example, surplus sludge generated when biological treatment (fermentation) of organic substances under aerobic or anaerobic conditions can be used. When sludge is used as a residue, from the viewpoint of reducing the weight of the elastomer composition and preventing adverse effects on the elastomer composition due to metal inclusion, sludge containing no iron-based flocculant, for example, sludge using an aluminum compound as the flocculant is used. Preferably, sludge containing no flocculant is more preferable.
　本発明のエラストマー組成物に配合し得る、有機物の発酵処理において生じる残滓の他の例としては、発酵菌等の細胞壁に含まれるペプチドグリカン、植物の細胞壁に含まれるセルロース粒子、ヘミセルロース粒子、リグニン、植物の細胞壁が連なった短繊維（セルロース短繊維、ヘミセルロース短繊維等）、またはそれらの混合物を含有する残滓が挙げられる。なお、残滓は、セルロース粒子およびヘミセルロース粒子の少なくとも一方を単体で含むことが好ましい。また、セルロース粒子およびヘミセルロース粒子の少なくとも一方と、短繊維との双方を含むことが更に好ましい。セルロース粒子およびヘミセルロース粒子の少なくとも一方を単体でエラストマー組成物に配合することにより、セルロース粒子およびヘミセルロース粒子がミクロな排水溝として働くことができるので、該エラストマー組成物を例えばスタッドレスタイヤに用いた場合にスタッドレスタイヤの性能（氷上性能等）を向上することができるからである。また、粒子と短繊維との双方を含むことにより、例えばエラストマー組成物をスタッドレスタイヤに使用した場合に、水分を吸収するという効果を奏することが可能だからである。更に、残滓は、ペプチドグリカン、セルロース粒子およびヘミセルロース粒子の少なくとも一方、並びにセルロース短繊維およびヘミセルロース短繊維の少なくとも一方を含むことが好ましい。ペプチドグリカンと、粒子と、短繊維とを含むことにより、例えばエラストマー組成物をスタッドレスタイヤに使用した場合に、水分を吸収するという効果を奏することが可能だからである。 Other examples of residues generated in the fermentation treatment of organic matter that can be blended in the elastomer composition of the present invention include peptidoglycan contained in the cell wall of fermenting bacteria, cellulose particles contained in the cell wall of plants, hemicellulose particles, lignin, plants And a residue containing short fibers (cellulosic short fibers, hemicellulose short fibers, etc.) in which the cell walls are continuous, or a mixture thereof. The residue preferably contains at least one of cellulose particles and hemicellulose particles alone. Further, it is more preferable that at least one of cellulose particles and hemicellulose particles and short fibers are included. By blending at least one of cellulose particles and hemicellulose particles alone into the elastomer composition, the cellulose particles and hemicellulose particles can function as a micro drainage groove. Therefore, when the elastomer composition is used, for example, in a studless tire This is because the performance (such as performance on ice) of the studless tire can be improved. In addition, by including both particles and short fibers, for example, when an elastomer composition is used in a studless tire, it is possible to achieve an effect of absorbing moisture. Furthermore, the residue preferably contains at least one of peptidoglycan, cellulose particles and hemicellulose particles, and at least one of cellulose short fibers and hemicellulose short fibers. This is because by including peptidoglycan, particles, and short fibers, for example, when an elastomer composition is used in a studless tire, an effect of absorbing moisture can be achieved.
　ここで、セルロース粒子およびヘミセルロース粒子とは、植物の細胞壁の主成分であり、アスペクト比が１以上５以下のものである。またセルロース短繊維およびヘミセルロース短繊維とは、植物の細胞壁が連なったものであり、アスペクト比が５超～５０以下のものである。 Here, cellulose particles and hemicellulose particles are the main components of plant cell walls and have an aspect ratio of 1 or more and 5 or less. The short cellulose fibers and the short hemicellulose fibers are a series of plant cell walls and have an aspect ratio of more than 5 to 50 or less.
　そして、本発明のエラストマー組成物の一態様では、上述した残滓には、残滓の主成分以外の成分が６質量％以下の割合で含まれている。ここで、残滓の主成分とは、前述した通り残滓を構成する主な成分を意味し、例えば発酵処理に用いられた発酵菌の細胞壁、若しくは発酵処理で分解されずに残った植物の細胞壁、またはそれらの混合物、並びに水が残滓の主成分となり得る。なお、発酵処理後の残滓に主成分以外の成分が６質量％より多く含まれている場合、ろ過、イオン交換、蒸留等の既知の手段を用いて主成分以外の成分を残滓から除去し、残滓中の主成分以外の成分の総量を６質量％以下としてから該残滓をエラストマー成分に配合することができる。 And in the one aspect | mode of the elastomer composition of this invention, components other than the main component of a residue are contained in the residue mentioned above in the ratio of 6 mass% or less. Here, the main component of the residue means the main components constituting the residue as described above, for example, the cell wall of the fermenting bacteria used in the fermentation treatment, or the cell wall of the plant that remains without being decomposed by the fermentation treatment, Or mixtures thereof, as well as water can be the main component of the residue. When the residue after fermentation treatment contains more than 6% by mass of components other than the main component, components other than the main component are removed from the residue using known means such as filtration, ion exchange, and distillation. After the total amount of components other than the main component in the residue is 6% by mass or less, the residue can be blended with the elastomer component.
　また、本発明のエラストマー組成物の別の態様では、上述した残滓の糖類、クエン酸およびアミノ酸の含有量の合計が、残滓の６質量％以下である。なお、発酵処理後の残滓に糖類、クエン酸およびアミノ酸が合計で６質量％より多く含まれている場合には、ろ過、イオン交換、蒸留、生物分解、化学分解、吸着等の既知の手段を用いてそれらの成分を残滓から除去し、残滓中の糖類、クエン酸およびアミノ酸の含有量の合計を残滓の６質量％以下としてから残滓をエラストマー成分に配合することができる。 Moreover, in another aspect of the elastomer composition of the present invention, the total content of the saccharide, citric acid and amino acid of the residue is 6% by mass or less of the residue. In addition, when the residue after fermentation treatment contains more than 6% by mass of saccharides, citric acid and amino acids, known means such as filtration, ion exchange, distillation, biodegradation, chemical degradation, adsorption and the like are used. It is possible to remove these components from the residue using the residue, and to make the total content of saccharide, citric acid and amino acid in the residue less than 6% by mass of the residue, and then add the residue to the elastomer component.
　ここで、残滓に含まれる糖類の量は、残滓の４質量％以下であることが好ましい。糖類は残滓を凝集させ易く、エラストマー成分中での残滓の分散性を悪化させ易いからである。なお、発酵処理後の残滓に糖類が４質量％より多く含まれている場合には、上述した手段の他に、遠心分離を用いて糖類を残滓中の水分と共に残滓から除去することもできる。具体的には、残滓の密度などを考慮して適宜調製した回転数・操作時間で、スクリューデカンター等の既存の遠心分離機を使用して分離することができる。また、遠心分離した残滓は、任意に、純水を添加して含水率を再度高めた上で乾燥を行うことができる。 Here, the amount of saccharide contained in the residue is preferably 4% by mass or less of the residue. This is because the saccharide easily aggregates the residue and tends to deteriorate the dispersibility of the residue in the elastomer component. In addition, when more than 4 mass% of saccharides are contained in the residue after fermentation treatment, in addition to the above-mentioned means, the saccharides can be removed from the residue together with the moisture in the residue using centrifugation. Specifically, separation can be performed using an existing centrifuge such as a screw decanter at a rotation speed and an operation time that are appropriately adjusted in consideration of the density of residue and the like. Moreover, the centrifuged residue can be dried after arbitrarily adding pure water to increase the water content again.
　なお、残滓は、乾燥して含水率を調整してからエラストマー成分に配合することができる。その場合、残滓は、乾燥前の状態において残滓の主成分以外の成分が６質量％以下、或いは、糖類、クエン酸およびアミノ酸の含有量の合計が残滓の６質量％以下であれば良く、乾燥後の残滓中に含まれる上記成分の量は問わない。また、残滓は、含水率を５～８０質量％としてからエラストマー組成物に配合することが好ましい。残滓の含水率が前記範囲にある場合、エラストマー成分に配合する際に残滓が凝集し難く、エラストマー組成物中で残滓が良好に分散するからである。ここで、残滓の乾燥は、例えば熱風乾燥、ドラム乾燥、フィルタープレス、熱板乾燥、燻煙処理等の既知の手段を用いて行うことができる。更に、残滓の含水率は、例えばケット水分計（ＦＤ－６２０、ケット科学研究所製）を用いて測定することができる。 The residue can be blended in the elastomer component after drying and adjusting the water content. In that case, the residue may be 6 mass% or less of components other than the main component of the residue in the state before drying, or the total content of saccharides, citric acid and amino acids may be 6 mass% or less of the residue. The amount of the above components contained in the subsequent residue is not limited. The residue is preferably blended into the elastomer composition after the water content is 5 to 80% by mass. This is because when the moisture content of the residue is in the above range, the residue hardly aggregates when blended with the elastomer component, and the residue is well dispersed in the elastomer composition. Here, the residue can be dried using known means such as hot air drying, drum drying, filter press, hot plate drying, smoke treatment, and the like. Further, the moisture content of the residue can be measured using, for example, a Kett moisture meter (FD-620, manufactured by Kett Science Laboratory).
　なお、残滓を乾燥させて含水率を調整する際の温度としては、作業効率の観点から、残滓を石臼方式等のろ過装置や、篩、フィルタープレス等でろ過した場合に生じるろ液の沸点よりも高い温度、好ましくは１３０℃～２５０℃の温度を用いることが好ましい。また、発酵処理が嫌気性発酵処理の場合、残滓の含水率の調整手段としては、木材を熱した時に出る煙で残滓を燻すことや、残滓を８００℃程度の高温で炭化処理することが含まれる燻煙処理が好ましい。燻煙処理を行うことにより、脱硫（消臭）および殺菌した取り扱いが容易な状態で残滓をエラストマー成分に配合することができるからである。 The temperature at which the residue is dried to adjust the water content is, from the viewpoint of work efficiency, from the boiling point of the filtrate produced when the residue is filtered with a stone mill type filtration device, a sieve, a filter press, etc. It is preferable to use a higher temperature, preferably 130 ° C to 250 ° C. In addition, when the fermentation process is an anaerobic fermentation process, the means for adjusting the moisture content of the residue includes dripping residue with smoke generated when the wood is heated and carbonizing the residue at a high temperature of about 800 ° C. Smoke treatment is preferred. This is because by performing the soot treatment, the residue can be blended with the elastomer component in a state where desulfurization (deodorization) and sterilized handling are easy.
　その他、残滓は、エラストマー成分への配合性および含水率の調整の容易性の観点から、粒径が１～６００μｍのものであることが好ましい。そして、粒径が６００μｍより大きい残滓を含むものについては、任意に、粉砕または篩い分けをした後に必要に応じて含水率を調整した上でエラストマー成分に配合することができる。なお、含水率の調整は粉砕または篩い分けの前に行っても良い。ここで、粒径とは、レーザー回折による粒子径測定（ＪＩＳ Ｚ８８２５－１）で求められ、該レーザー回折による方法において、粒子等の長軸－短軸の平均（球形と捉えられる）を測定して得られる値である。 In addition, it is preferable that the residue has a particle size of 1 to 600 μm from the viewpoint of blendability into the elastomer component and ease of adjustment of the moisture content. And about what contains the residue with a particle size larger than 600 micrometers, it can mix | blend with an elastomer component, after adjusting a moisture content as needed, after grind | pulverizing or sieving. The moisture content may be adjusted before pulverization or sieving. Here, the particle diameter is determined by particle diameter measurement by laser diffraction (JIS Z8825-1), and in this laser diffraction method, the average of the major axis and the minor axis of particles, etc. (taken as a sphere) is measured. Is the value obtained.
　また、本発明のエラストマー組成物は、残滓の配合量が、エラストマー成分１００質量部に対して１～５０質量部であることが好ましい。残滓の配合量を１質量部以上とすることで環境負荷の低減を十分に達成することができ、また、残滓の配合量を５０質量部以下とすることで、代替原料を使用しないエラストマー組成物と同程度の性能を有するエラストマー組成物を提供することができるからである。 In the elastomer composition of the present invention, the amount of residue is preferably 1 to 50 parts by mass with respect to 100 parts by mass of the elastomer component.
