【０００５】
本発明の課題は、炭化工程で、蒸気式熱分散装置を取り入れることにより、過熱蒸気で該材料に高速で噴射処理を施すことにより、燃焼による有機ガスの処理や臭気の発生を少なくし所定の炭化物を容易に得る方法を提供することにある。
【０００６】
また本発明の課題は、炭化工程と焼成工程を別々に行い、それにより得られる炭化物及び焼成物を別個に微粉末化し、それ等を別々に又は混合することで、目的に応じた黒色顔料を容易に得る方法を提供することにある。
【０００７】
【課題を解決するための手段】
本発明は以下の発明に係る。
１．動物性蛋白質繊維から成る材料を高温蒸気により高速に噴射して熱分解することを特徴とする動物性蛋白質繊維の炭化物の製造方法。
２．動物性蛋白質繊維から成る材料を高温蒸気により高速に噴射して熱分解して得られた炭化物を無酸素に近い真空焼成炉に入れ、高温で熱処理することを特徴とする動物性蛋白質繊維の焼成物の製造方法。

【０００８】
【発明の実施の形態】
本発明は動物性蛋白質繊維を原料とするが、以下簡略の為絹繊維について説明する。本発明による絹材料の裁断は、原料の定量輸送を行うスクリューコンベアー方式による焼成のため、１〜１０ｍｍ、好ましくは２〜４ｍｍ程度に裁断した原料を用いる。また、原料を乾燥部へ定量提供するために、ホッパー内部で飛散することを防止するため、また乾留ガス排出フードに吸い込まれないようにするため、水分を補水した原料にすることが好ましい。
【０００９】
このようにして短く裁断された絹原料は、高温加熱蒸気式分解装置により高温の過熱蒸気を絹材料に高速で噴射し、高効率で熱分解を施し絹原料の定量輸送を行う。炭化工程は３００〜８００℃、好ましくは４００〜６００℃で行う。また設定時間と燃料の供給を調整することにより、元素分析や組成の異なる、従って色の異なる種々の炭化物を得ることができる。
【００１０】
前記炭化工程で得られた絹炭化物を、再度真空熱処理炉で焼成する。焼成工程は通常９００〜１５００℃前後、好ましくは１０００〜１３００℃前後に加熱する。炭化工程で得られた絹炭化物を、焼成方式の異なる真空熱処理炉において、焼成を行うことにより本発明の優れた黒色顔料を得ることができる。絹繊維などのような蛋白質繊維を、一段階の非酸化雰囲気炉で熱処理することは、絹繊維が保持する有機成分の焼成によるガス化により、タール状の溶解物の溶出が激しく、真空ポンプの吸気装置の目詰まりを起こし、真空常態の炉内気圧を一定に維持することを困難にし、又、近傍界に著しい臭気を発生し、継続的に材料を形成することを困難であったが、炭化と焼成の２つの工程を施すことでこれらの問題点を解決した。
【００１１】
前記炭化物を作成する炭化工程では、例えば「図１」に記載の高温過熱蒸気式熱分解システム機（商品名）を利用することができる。この装置では、燃料ガスにより加熱発生した高温の蒸気を、熱移送管を通して処理物に噴射し熱分解を施す工程と、処理物がこの工程により発生する分解ガス自体を、再燃料化による装置で有機ガスの処理を再利用し、炭化処理を施すことで有機ガスの発生を少なくし、無酸素に近い焼成条件が施されているため、効率の良く炭化物を得ることができる。
【００１２】
こうして得られた炭化物は、過熱蒸気の噴射時間や設定温度により、色の異なる種々の炭化物を得ることができる。
【００１３】
焼成工程は、更に高温の非酸化雰囲気の真空熱処理炉で焼成を実施するが、原料が炭化物になっているため真空熱処理炉に装填される炭化物は、炉内気圧が常温常圧であることを認識した後装填し、その後、炉内条件を無酸素に近い状態になるように通常０．０１〜０．１ｔｏｒｒ、好ましくは０．０２〜０．０４ｔｏｒｒに減圧し通常約０．５〜５時間、好ましくは１〜３時間焼成を施すが、有機ガスや臭気の発生も少なく、タール成分の溶出も微少になり、周囲の環境対策の課題を解消し、継続的な生産体制も確立することを可能にし、又、真空焼成を行う焼成時間も短縮され、コスト的にも安値になり品質の安定した製品を回収することが可能である。
【００１４】
このようにして得られた材料の粉末化については、炭化工程で得られた炭化物と焼成工程で得られた焼成物を用途により適宜混合し、ボールミル形式の粉砕機を使用することで、通常１〜１０μｍ、好ましくは３〜４μｍの粒度に粉砕するのが好ましい。
【００１５】
本発明の黒色顔料は種々の用途に用いられるが、代表例として例えばアイライナー、マスカラ、マユ墨、ヘアカラーなどの化粧用材料として使用することができる。化粧用材料中に本発明の黒色顔料を約０．１〜１０重量％、好ましくは約１〜５重量％配合するのが好適である。
【００１６】
【実施例】
以下に本発明の実施例を示すが、なんらこれらに限定されるものではない。
【００１７】

【００１９】
このようにして得られた炭化工程の炭化物と焼成工程で得られた材料を「（株）セイシン企業社製のシングルトラックミル（商品名）」を使用して粉砕し、レザー回転式粒度分析計（上記社製によるＬＡＳＥＲ ＰＲＯ ７０００Ｓ）で測定し所定の粉末を分級器を併用することで、粒度別の粉末を得て平均３μｍの超微粉末をそれぞれ得た。
【００２０】
粘性のある黒色顔料の製法は、用途により炭化工程で得られた炭化物と焼成工程で得られた焼成物の配合率を適宜選択し混合して使用するが、粘性を強く求められる材料は、炭化物の割合を多くし、黒色の彩度を要求される用途では、焼成物を多く配合することで、特色を発揮することが可能である。又各５０ｗｔ％で混合した混合顔料１〜１５ｗｔ％と、水分９９〜８５ｗｔ％配合した溶液は、即時に溶解し分散剤を必要とせず、水中に永久的に分散し沈殿しない特性を発揮する特徴を有している。
【００２１】
本実施例で得られた炭化物及び焼成物のＣ・Ｈ・Ｎ重量比をＣＨＮ元素分析装置、機種「機種パーキン・エルマー２４００型ＣＨＮ元素分析装置」を用い、検出方法は、フロンタルガスクロマトグラフ法にて行い、機能・酸化炉縦型９２５℃、還元炉縦型６４０℃にて測定した。
【００２２】
【表１】

【００２３】
本発明により得られる黒色顔料は、官能基を残した炭化物になり絹繊維の特性を持つ保温性、保水性、皮膚への親和性などの優れた特性が他の材料と配合して得られる製品に反映しており、例えば、絹粉末の高分子材料に重量比２％程度配合することにより、色彩は艶のある黒色を生じ粘性を付帯した付着力のある現象を示し、特別な接着剤を必要としない。又上記材料が水や油に容易に分散し流動性の良い性質を有しているため、スプレードライ方式の製品に利用することも可能である。この方法ではスプレー製品の目的により用材の内容が変わるため、あらかじめ粒子の大きさ等を使用目的に応じて、適当に微砕化することが好ましい。
【００２４】
具体的な例として、この方法を用いて次のような条件で絹焼成物のディスパーションを作成した。

【００２５】
【発明の効果】
以上説明したように、本発明により得られる黒色顔料は、従来利用されている酸化チタン類などの無機物から生成される黒色カーボン類では無く、絹繊維等の動物性蛋白質繊維の特性を残したまま二つの工程を施して、得られる黒色粉体で構成された材料で、無機塩などの不純物が全く含まれず人体に安全で又分散性と剥離性の良い特性と配合量と材質を加減することにより、黒色顔料としての用途を超える利用範囲を備えており、多くの産業資材として有用である。
【００２６】
また本発明は、絹繊維等の動物性蛋白質繊維を焼成して黒色カーボンを作成するものではなく、官能基を保持した焼成物を作成することにより、従来、化粧品材料として使用されている黒色カーボン類とは、炭素成分の構成を異質にした材料を提供するもので、炭素以外の成分を保持した材料であり、窒素や酸素を保有した官能基を有し、水性や油性の溶剤に溶けやすく、有害な溶剤を配合することを必要とせず、従来の黒色顔料とは違う比重の軽く粘性を保持した材料の提供を可能にしている。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for producing a black pigment from animal protein fibers such as silk fibers.
[0002]
[Prior art]
Among pigments used to impart opaque color to objects as powders that do not dissolve in solvents such as water and oil, black pigments are composed of carbon-based raw materials such as carbon black and graphite. Carcinogenicity has been pointed out due to the effects of pentbilene and the like, and blending is banned in other countries.
[0003]
In addition, titanium oxide and zinc sublimation used to increase the hiding power are used as a vehicle, but cosmetic materials corresponding to eyebrows required for these products have a high tension on eyelashes. It is premised that there is no microbial contamination and irritation along with conditional contents such as curling use time.
[0004]
[Problems to be solved by the invention]
The method of heat-treating the protein fiber in a non-oxidizing atmosphere furnace causes various heating problems due to the organic components held by the protein fiber, and particularly, the elution of the organic gas and tar generated at around 450 ° C. is remarkable. This method is not practical because it induces damage to the sintering furnace and failure of the pressure control equipment, emits a noticeable odor in the near field, and leaves many problems.
[0005]
An object of the present invention is to reduce the generation of odor and the processing of organic gas by combustion by applying a high-speed injection treatment to the material with superheated steam by incorporating a steam-type heat dispersion device in the carbonization step. It is to provide a method for easily obtaining a carbide.

Another object of the present invention is to separately perform the carbonization step and the calcination step, separately pulverize the obtained carbide and the calcination substance, and separately or mix them to obtain a black pigment according to the purpose. It is to provide a method of obtaining easily.
[0007]

[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Although the present invention uses animal protein fibers as raw materials, silk fibers will be described below for simplicity. In the cutting of the silk material according to the present invention, a raw material cut to 1 to 10 mm, preferably about 2 to 4 mm is used for baking by a screw conveyor system for quantitatively transporting the raw material. In addition, in order to supply the raw material to the drying unit in a fixed amount, it is preferable to use a raw material with water replenishment in order to prevent the raw material from being scattered inside the hopper and to prevent the raw material from being sucked into the carbonization gas discharge hood.
[0009]
The silk material cut short in this way is injected with high-temperature superheated steam at a high speed by a high-temperature heating steam type decomposition device, and is thermally decomposed with high efficiency to carry out quantitative transport of the silk material. The carbonization step is performed at 300 to 800C, preferably 400 to 600C. Further, by adjusting the set time and the supply of fuel, it is possible to obtain various carbides having different elemental analyzes and compositions, and thus different colors.
[0010]
The silk carbide obtained in the carbonization step is fired again in a vacuum heat treatment furnace. In the firing step, heating is usually performed at about 900 to 1500 ° C, preferably about 1000 to 1300 ° C. The excellent black pigment of the present invention can be obtained by baking the silk carbide obtained in the carbonization step in vacuum heat treatment furnaces having different baking methods. Heat-treating protein fibers such as silk fibers in a one-stage non-oxidizing atmosphere furnace requires gasification of the organic components held by the silk fibers by gasification, resulting in severe elution of tar-like dissolved substances. It caused clogging of the intake device, making it difficult to maintain a constant pressure in the furnace in a vacuum normal state, and generating a noticeable odor in the near field, making it difficult to continuously form a material. These problems were solved by performing two steps of carbonization and firing.
[0011]
In the carbonization step for producing the carbide, for example, a high-temperature superheated steam-type pyrolysis system machine (product name) described in FIG. 1 can be used. In this apparatus, a process of injecting high-temperature steam generated by heating with a fuel gas to a processed product through a heat transfer pipe to perform thermal decomposition, and a device by re-fueling a cracked gas itself generated in the process by the process. Since the treatment of the organic gas is reused and the carbonization treatment is performed, the generation of the organic gas is reduced, and the calcination conditions close to oxygen-free are performed, so that the carbide can be obtained efficiently.
[0012]
From the carbide thus obtained, various carbides having different colors can be obtained depending on the injection time of superheated steam and the set temperature.
[0013]
In the firing step, firing is performed in a vacuum heat treatment furnace in a non-oxidizing atmosphere at a higher temperature.However, since the raw material is carbide, the carbide loaded in the vacuum heat treatment furnace must have a furnace pressure of normal temperature and normal pressure. After recognizing and loading, after that, the pressure in the furnace is usually reduced to 0.01 to 0.1 torr, preferably 0.02 to 0.04 torr so that the condition in the furnace becomes almost oxygen-free, and usually about 0.5 to 5 hours. Preferably, baking is carried out for 1 to 3 hours, but the generation of organic gas and odor is small, the elution of tar components is also small, the problems of surrounding environmental measures are solved, and a continuous production system is established. In addition, the baking time for performing vacuum baking is shortened, the cost is reduced, and a product of stable quality can be collected.
[0014]
Regarding the pulverization of the material obtained in this way, the carbide obtained in the carbonization step and the fired substance obtained in the firing step are appropriately mixed according to the intended use, and a ball mill type pulverizer is used. It is preferred to grind to a particle size of from 10 to 10 μm, preferably 3 to 4 μm.
[0015]
Although the black pigment of the present invention is used for various uses, as a typical example, it can be used as a cosmetic material such as eyeliner, mascara, mayu ink and hair color. It is suitable to incorporate the black pigment of the present invention in the cosmetic material in an amount of about 0.1 to 10% by weight, preferably about 1 to 5% by weight.
[0016]
【Example】
Hereinafter, examples of the present invention will be described, but the present invention is not limited thereto.
[0017]
Example 1
After the silk raw material is cut into 2 to 4 mm by a guillotine-type cutting machine, water is replenished with water to adjust the temperature of the silk raw material so that the raw material is not sucked into the carbonization gas discharge hood. Water is replenished in the range of 10 wt% of water with respect to 100 wt% of the raw material, and then the raw material is put into the raw material receiving hopper, is quantitatively transferred by a screw conveyor, and is placed in a drying chamber using exhaust heat at a temperature of about 100 ° C. for 30 minutes. Heat drying is performed, and the raw material transferred quantitatively by a preset rotary kiln method is heated and dried, and then the high-temperature steam created by the superheated steam generator set at a high temperature of 500 ° C. is jetted at a high speed. The raw material was transferred by a transfer conveyor, and superheated steam was injected at a high speed for 50 minutes to produce pyrolyzed carbide. In this embodiment, a "high-temperature superheated steam-type pyrolysis system machine (product name) of STM Co., Ltd." was used.
[0018]
The silk carbide obtained in the carbonization step was loaded into a “cooling type vacuum heat treatment furnace VBG-121830 (trade name) manufactured by Nippon Hayes Co., Ltd.”, and the furnace was set to a furnace pressure of 0.03 torr and a temperature of 1250 ° C. After baking for 2 hours and insulated, cooling was performed for about 4 hours using nitrogen gas together, and it was confirmed that the furnace pressure and the furnace temperature were normal temperature and normal pressure. I got something.
[0019]
The carbide obtained in the carbonization process and the material obtained in the firing process were pulverized using a “Single Track Mill (trade name) manufactured by Seishin Enterprise Co., Ltd.”, and a leather rotary particle size analyzer was used. (Laser PRO 7000S manufactured by the above company) and a predetermined powder was used in combination with a classifier to obtain powders of different particle sizes to obtain ultrafine powders having an average of 3 μm.
[0020]
The method for producing a viscous black pigment is to appropriately select and mix the blending ratio of the carbide obtained in the carbonization step and the fired substance obtained in the firing step depending on the application. In applications where the ratio of black is increased and black color saturation is required, it is possible to exhibit a special color by adding a large amount of fired products. In addition, a solution containing 1 to 15 wt% of a mixed pigment mixed with 50 wt% of each and 99 to 85 wt% of moisture dissolves instantly, does not require a dispersant, and exhibits characteristics of being permanently dispersed and not precipitated in water. have.
[0021]
Using a CHN elemental analyzer and a model “Model Perkin-Elmer 2400 type CHN elemental analyzer”, the C / H / N weight ratio of the carbide and the calcined product obtained in this example was determined by a frontal gas chromatographic method. The function was measured at 925 ° C. vertical type in the oxidation furnace and 640 ° C. vertical type in the reduction furnace.
[0022]
[Table 1]

[0023]
The black pigment obtained according to the present invention is a carbonized product having a functional group, and is a product obtained by blending other materials with excellent properties such as heat retention, water retention, and affinity for skin having the properties of silk fiber. For example, by blending about 2% by weight with a polymer material of silk powder, the color shows a glossy black color and shows a sticky phenomenon with viscosity, and a special adhesive is used. do not need. In addition, since the above-mentioned materials easily disperse in water or oil and have good fluidity, they can be used for spray-dry products. In this method, since the contents of the material vary depending on the purpose of the spray product, it is preferable to appropriately pulverize the particle size and the like in advance according to the purpose of use.
[0024]
As a specific example, a dispersion of a fired silk product was prepared using this method under the following conditions.
Water: 100 parts by weight silk baked product 3 μm: 2 parts by weight Specific gravity: 1.16
Color: Black Viscosity: about 100 cps
Working liquid volume: 9L
Dispersant Polymer silk powder: micro-suspension: completely dispersed after 24 hours
【The invention's effect】
As described above, the black pigment obtained according to the present invention is not black carbons produced from inorganic substances such as conventionally used titanium oxides, but retains the characteristics of animal protein fibers such as silk fibers. A material composed of black powder obtained by performing two processes, containing no impurities such as inorganic salts at all, safe for the human body and having good dispersibility and releasability. Thus, it has a use range exceeding the use as a black pigment, and is useful as many industrial materials.
[0026]
Further, the present invention does not produce black carbon by baking animal protein fibers such as silk fibers, but by producing a calcined product having a functional group, the black carbon conventionally used as a cosmetic material is produced. Classes are materials that provide a material with a different composition of carbon components, are materials that hold components other than carbon, have a functional group that holds nitrogen or oxygen, and are easily soluble in aqueous or oily solvents. This makes it possible to provide a light-weight, light-viscosity material having a specific gravity different from that of the conventional black pigment without the need for blending a harmful solvent.
