Description
この発明は、着色効果として木炭を使用することを特徴とする熱可塑性樹脂との複合材料に関するものである。 The present invention relates to a composite material with a thermoplastic resin characterized by using charcoal as a coloring effect.
植物由来の原料を利用し、石油資源をなるべく使用することなく環境に与える負荷を減少させる意識は、今日とても高まっており、使用する原料にもそれが反映されなければならない背景が存在する。 The awareness of using plant-derived raw materials to reduce the burden on the environment without using petroleum resources as much as possible is increasing today, and there is a background that must be reflected in the raw materials used.
その中で石油に由来する熱可塑性樹脂には、着色剤としてカーボンブラックを使用して着色していた。このため、石油由来の着色剤に頼ることから離脱し、環境に配慮し、有限な石油資源を大切にするといった視点からも、カーボンブラックに代わる着色剤が求められていたが、現行になかった。 Among them, the thermoplastic resin derived from petroleum was colored using carbon black as a colorant. For this reason, there has been a demand for a colorant that replaces carbon black from the viewpoint of leaving away from relying on colorants derived from petroleum, considering the environment, and valuing limited petroleum resources. .
生分解性樹脂と混錬して着色効果を出すカーボンブラックを含む着色組成物に代わる着色組成物が市場に求められていたが、現行になかった。 There has been a demand for a colored composition that replaces a colored composition containing carbon black that is kneaded with a biodegradable resin to produce a coloring effect, but it has not been present.
生分解性樹脂を、土壌もしくは堆肥などの樹脂を分解させる環境において、含まれる着色効果のあるカーボンブラックが分解せずに残る問題があったがそれを解決する手段がこれまで提案されていなかった。 In an environment where biodegradable resins are decomposed into resins such as soil or compost, there was a problem that the carbon black contained in the coloring effect remained without being decomposed, but no means to solve it had been proposed so far. .
本発明は、石油由来の着色剤に頼ることから離脱し、環境に配慮し、有限な石油資源を大切にするといった視点から、木材あるいは廃材となる木材を利用して微粉炭を製造し、これを生分解性樹脂、植物由来の樹脂と混錬して、さらには汎用樹脂やリサイクルした再生ペレットに混錬して着色効果を持たせるものである。 The present invention, from the point of view of leaving away from relying on petroleum-derived colorants, considering the environment and valuing limited petroleum resources, produces pulverized coal using wood or waste wood. Is kneaded with a biodegradable resin or a plant-derived resin, and further kneaded with a general-purpose resin or recycled recycled pellets to give a coloring effect.
さらに本発明は、生分解性樹脂が土壌もしくは堆肥などの樹脂を分解させる環境において、組成中に含まれる着色効果として用いられているカーボンブラックが分解せずに残る問題を解決するものである。 Furthermore, the present invention solves the problem that carbon black used as a coloring effect contained in the composition remains without being decomposed in an environment where the biodegradable resin decomposes the resin such as soil or compost.
本発明における熱可塑性樹脂複合材において組成に含む微粉炭は、石油を原料とする従来のカーボンブラックから木材もしくは木の廃材を熱焼成し、炭化したものに着色効果を持たせているので、廃材などの再利用することもつながり、資源の有効活用に効果をもたらすものとなる。 The pulverized coal contained in the composition of the thermoplastic resin composite material of the present invention is a waste material because the waste material of wood or wood is heat-fired from carbon black as a raw material and carbonized to give a coloring effect. Reuse such as will also lead to effective use of resources.
本発明による熱可塑性樹脂複合材は、上記の課題を解決するために、木材を原料として熱焼成した微粉炭と熱可塑性樹脂からなることを特徴としている。この熱可塑性樹脂複合材における微粉炭は粒形が0.001nm〜10mmとなる炭粉末を組成に含み、熱可塑性樹脂を母材とする。 In order to solve the above-mentioned problems, the thermoplastic resin composite material according to the present invention is characterized by comprising pulverized coal fired from wood as a raw material and a thermoplastic resin. The pulverized coal in this thermoplastic resin composite material contains charcoal powder having a particle shape of 0.001 nm to 10 mm in the composition, and a thermoplastic resin as a base material.
また、木材以外の微粉炭の原料としては竹、いぐさ、稲、藁、麻、ケナフ等を使用することもできる。 Bamboo, igusa, rice, straw, hemp, kenaf and the like can also be used as raw materials for pulverized coal other than wood.
本発明による熱可塑性樹脂複合材の母材には生分解性樹脂であることはたいへん望ましい。土中、あるいは堆肥中での分解において微粉炭が分解せずに残ることがないからである。母材となる生分解性樹脂としては、ポリ乳酸系樹脂、脂肪族芳香族ポリエステル系樹脂、脂肪族ポリエステル系樹脂、生分解を有す芳香族ポリエステル系樹脂、ポリカプロラクトン系樹脂さらに澱粉基コポリエステル系樹脂などが挙げられる。その中から少なくとも1種類以上を組成に含むことができる。 It is highly desirable that the base material of the thermoplastic resin composite material according to the present invention is a biodegradable resin. This is because pulverized coal does not remain undecomposed during decomposition in soil or compost. Biodegradable resins used as base materials include polylactic acid resins, aliphatic aromatic polyester resins, aliphatic polyester resins, aromatic polyester resins having biodegradation, polycaprolactone resins, and starch-based copolyesters. Based resins and the like. At least one of them can be included in the composition.
さらに本発明による熱可塑性樹脂複合材の母材にはカプロラクトン−ブタンジオール−コハク酸共重合体、酢酸セルロース系可塑性樹脂、澱粉脂肪酸エステル系樹脂、ポリビニルアルコール系樹脂、ポリヒドロキシブチレート（PHB）またはポリヒドロキシバリレート（PHV）もしくはその共重合体（PHVB）ポリ３ヒドロキシ酪酸３ヒドロキシヘキサン酸などを含む共重合ポリエステルであるポリヒドロキシアルカノエート（PHA）などの中から少なくとも1種類以上の生分解性樹脂を重量％で0.01〜40％含めることも分解速度の調整等の目的で含めることもできる。 Further, the base material of the thermoplastic resin composite according to the present invention includes caprolactone-butanediol-succinic acid copolymer, cellulose acetate-based plastic resin, starch fatty acid ester-based resin, polyvinyl alcohol-based resin, polyhydroxybutyrate (PHB) or Polyhydroxy alkanoate (PHA) which is a copolyester containing polyhydroxy valerate (PHV) or its copolymer (PHVB) poly 3-hydroxybutyric acid 3-hydroxyhexanoic acid etc. The resin can be contained in an amount of 0.01 to 40% by weight or for the purpose of adjusting the decomposition rate.
加えて石油原原料の枯渇が問題視される場合、母材を植物由来の樹脂、例えばポリ乳酸系樹脂に現行の汎用樹脂、例えばポリプロピレン系樹脂、ポリエチレン系樹脂、ポリカーボネード系樹脂、ポリエステル系樹脂、ナイロン系樹脂などの中から少なくとも1種類以上を組み合わせることにより、有効な資源の利用が可能となる。さらに再生品もしくはリサイクルペレットを活用すればさらに環境負荷を下げることができる。 In addition, when the depletion of petroleum raw materials is regarded as a problem, the base material is a plant-derived resin, such as a polylactic acid-based resin, a current general-purpose resin such as a polypropylene-based resin, a polyethylene-based resin, a polycarbonate-based resin, a polyester-based resin, By combining at least one type of nylon resin, it is possible to use effective resources. Furthermore, the environmental load can be further reduced by using recycled products or recycled pellets.
本発明における熱可塑性樹脂複合材の目的は、環境負荷を低めることにあるゆえに、分散を良好にするための分散剤や安定剤、難燃剤を含む添加剤等の使用に関しては、土壌を汚染する可能性のあるものや、人体に悪影響を与える可能性のあるものは避けるべきである。 Since the purpose of the thermoplastic resin composite material in the present invention is to reduce the environmental load, the use of a dispersant, a stabilizer, an additive containing a flame retardant, etc. for improving the dispersion contaminates the soil. Things that might be possible or that could harm the human body should be avoided.
本発明における熱可塑性樹脂複合材の混錬には、あらかじめ微粉炭を重量％にして1％〜99％の高充填濃度で着色組成物を製造しておき、それを再度混錬することにより平易に着色することもできる。 In the kneading of the thermoplastic resin composite material in the present invention, it is easy to prepare a colored composition at a high filling concentration of 1% to 99% with pulverized coal in weight% in advance and knead it again. It can also be colored.
これまで熱可塑性樹脂の着色効果には主としてカーボンブラックが利用されていた。しかし本発明にように木炭に着色効果をもたせることを特徴とする熱可塑性樹脂複合材であれば、石油資源の利用を軽減することができる。これを植物由来の樹脂であるポリ乳酸と混錬して熱可塑性樹脂複合材を製造すれば、全く石油原料を使用せずに済む効果がある。機械的強度や成形性を考慮すると、植物由来の樹脂であるポリ乳酸に加えて組成中に従来の汎用樹脂を含むこともできる。その場合でも石油資源の利用を軽減する効果が生まれる。加えて本発明による熱可塑性樹脂複合材の母材を生分解性樹脂とする場合でも、分解する環境下でカーボンブラックだけが分解せずに残るといった問題を解消することができる。 Until now, carbon black has been mainly used for the coloring effect of thermoplastic resins. However, the use of petroleum resources can be reduced if the thermoplastic resin composite is characterized in that charcoal has a coloring effect as in the present invention. If this is kneaded with a polylactic acid which is a plant-derived resin to produce a thermoplastic resin composite, there is an effect that it is not necessary to use petroleum raw materials at all. In consideration of mechanical strength and moldability, a conventional general-purpose resin can be included in the composition in addition to polylactic acid which is a plant-derived resin. Even in that case, the effect of reducing the use of oil resources is produced. In addition, even when the base material of the thermoplastic resin composite material according to the present invention is a biodegradable resin, it is possible to solve the problem that only carbon black remains undecomposed in a decomposing environment.
着色組成物に含まれる微粉炭は、0.001nm〜10mm 程度に微粉状にした後、熱焼成するか、もしくは熱焼成した後に微粉状して0.001nm〜10mmの粒形にする。また微粉状にする工程は、使用する用途により任意にその形状が変えられるので、様々な用途に合わせて製造できるが、いずれの場合でも成形不良等の原因にならない程度に微粉状する必要がある。射出成形であれば粒形は0.5ｍｍ以下、さらには0.15ｍｍ以下がさらに望ましい。またフィルムやシートの着色であれば、厚みにもよるが粒形は0.1mm以下さらには0.005ｍｍ以下が望ましい。 The pulverized coal contained in the coloring composition is pulverized to about 0.001 nm to 10 mm and then heat-fired, or heat-fired and then finely pulverized into a particle shape of 0.001 nm to 10 mm. In addition, since the shape of the step of making fine powder can be arbitrarily changed depending on the application to be used, it can be manufactured according to various applications, but in any case, it is necessary to make it fine powder so as not to cause molding defects. . For injection molding, the particle shape is preferably 0.5 mm or less, more preferably 0.15 mm or less. If the film or sheet is colored, the particle shape is preferably 0.1 mm or less, more preferably 0.005 mm or less, depending on the thickness.
上記の方法により製造される松、スプルス、ヒノキ、杉等の木材、さらには廃材の再利用であればさらに望ましい。微粉炭で粒形が0.001nm〜10mmとなる炭粉末の中から少なくとも1種類以上を組成中に重量％で0.01％〜99.9％含むことができるが、望ましくは重量％で0.1％〜40％程度である。 It is more desirable if it is reused of wood such as pine, spruce, cypress and cedar produced by the above method, and waste wood. At least one kind of charcoal powder having a particle shape of 0.001 nm to 10 mm in pulverized coal can be included in the composition in an amount of 0.01% to 99.9%, preferably about 0.1% to 40% by weight. It is.
廃材の再利用ということであれば竹、イグサ、稲、ケナフなど天然原料を上記の方法で熱焼成して炭化物を製造し、本発明における熱可塑性樹脂複合材に混錬して着色することも可能である。 If it is to recycle waste materials, natural materials such as bamboo, rush, rice and kenaf are calcined by the above method to produce carbides, and they may be kneaded and colored into the thermoplastic resin composite in the present invention. Is possible.
生分解することを特徴としたポリ乳酸系樹脂、脂肪族芳香族ポリエステル系樹脂、脂肪族ポリエステル系樹脂、生分解を有する芳香族ポリエステル系樹脂、ポリカプロラクトン系樹脂さらに澱粉基コポリエステル系樹脂などが挙げられる。その中から少なくとも1種類以上の樹脂を母剤とし着色効果を持たせる場合であれば、組成中に重量％にして0.１％〜99.9％、組成中の母材の重量％にして60％〜99.9％がさらに望ましい。 Polylactic acid resin, aliphatic aromatic polyester resin, aliphatic polyester resin, biodegradable aromatic polyester resin, polycaprolactone resin, and starch-based copolyester resin characterized by biodegradation Can be mentioned. If at least one kind of resin is used as a base material to give a coloring effect, 0.1% to 99.9% by weight in the composition, 60% by weight% of the base material in the composition ~ 99.9% is more desirable.
あらかじめ別途、着色組成物を混錬しておき、それを再混錬する場合では着色組成物中に含む微粉炭の割合は重量％にして0.1％〜99.9％に高充填することができる。さらに望ましくは、粉炭の割合は重量％にして5％〜60％である。 In the case of separately kneading the colored composition in advance and re-kneading it, the ratio of the pulverized coal contained in the colored composition can be highly filled to 0.1% to 99.9% by weight%. More preferably, the proportion of pulverized coal is 5% to 60% in weight%.
本発明における熱可塑性樹脂複合材の母材となる樹脂であるが、微粉炭による着色という特長を活かすためには、植物由来の樹脂であるポリ乳酸系樹と汎用樹脂からなるバイオマスプラスチックにすることもできる。組成中に含むポリ乳酸系樹脂はポリ乳酸系樹脂重量％にして0.1％〜99.9％、汎用樹脂は重量％にして0.1％〜99.9％にすることができる。汎用樹脂の例としてはポリプロピレン系樹脂、ポリエチレン系樹脂、ポリエステル系樹脂、ポリカーボネード系樹脂などが上げられる。その中から少なくとも1種類以上を選択することができる。さらには汎用樹脂の中でも再生ペレットなど、リサイクルしているものであれば、石油を含めて有資源のためにはさらに望ましいものとなる。さらに熱可塑性樹脂複合材における組成中の割合は重量％にしてポリ乳酸系樹脂3％〜99％、汎用樹脂も同様に3％〜99％で成形条件、使用するに際して必要となる機械的物性などを考慮して、組成を組むことが必要である。 Although it is a resin that is a base material for the thermoplastic resin composite material in the present invention, in order to make use of the feature of coloring with pulverized coal, it should be made into a biomass plastic composed of a polylactic acid tree that is a plant-derived resin and a general-purpose resin You can also. The polylactic acid resin contained in the composition can be 0.1% to 99.9% in terms of polylactic acid resin weight%, and the general resin can be 0.1% to 99.9% in weight%. Examples of general-purpose resins include polypropylene resins, polyethylene resins, polyester resins, polycarbonate resins, and the like. At least one of them can be selected. Further, among general-purpose resins, recycled ones such as recycled pellets are more desirable for resources including petroleum.
