Description
各種化学繊維、天然繊維、連続気泡フォーム、紙、デンプン、炭水化物などに不燃性、耐熱性を付与させる方法を提供する。特にプラスチック応用製品は、燃えて当たり前の製品であるプラスチック製品の不燃化操作の対象となる素材は具体的には前記記載の各種用途の化学繊維のうち吸湿性機能を備えているもの、連続気泡ウレタンフォーム、連続気泡ポリエチレンフォームの様に柔軟でセル構造を持つものが簡易な浸透定着操作で不燃化可能です。この不燃化基礎技術を応用することで、混載される一般家庭から排出される各種ごみやプラスチック系産業廃棄物なども熱溶融することなく焼却処理から一気にカーボン化させる炭素化技術になる。したがって熱溶融しない為、焼却炉を傷めることはない。また、これらの焼成炭化物とでんぷん系生分解性不燃性ボンドを結合剤として圧縮成形する操作でセラミックスの様な１５００〜１８００℃±の超耐熱素材ＣＣコンポジットパネルが得られる。産業廃棄物、一般ゴミ炭化物のケミカルリサイクルによる不燃耐熱素材などが誕生する。したがって埋め立て処分される量も激減する。人、環境にとっても極めて有効な方法を提供するものである。 Provided is a method for imparting incombustibility and heat resistance to various chemical fibers, natural fibers, open-cell foam, paper, starch, carbohydrates and the like. In particular, plastic-applied products are materials that are subject to the incombustibility operation of plastic products, which are natural products that burn, and specifically, those having the hygroscopic function among the above-described chemical fibers, open cell A flexible and cell structure such as urethane foam or open-cell polyethylene foam can be made non-combustible with a simple penetration fixing operation. By applying this incombustible basic technology, it becomes a carbonization technology to carbonize all garbage and plastic industrial waste discharged from mixed households at once from incineration without melting. Therefore, since it does not melt, it will not damage the incinerator. In addition, a super heat resistant material CC composite panel having a temperature of 1500 to 1800 ° C. such as ceramics can be obtained by an operation of compression molding using these calcined carbide and starch-based biodegradable incombustible bond as a binder. Incombustible and heat-resistant materials are born by chemical recycling of industrial waste and general garbage carbide. Therefore, the amount of landfilled waste is drastically reduced. It provides an extremely effective method for people and the environment.
植物由来の木材、紙、繊維の不燃化は、広く一般に知られている。不燃化にとって有効な薬剤は、燐酸水素二アンモニュウム、硼砂、ホウ酸、塩化バリュウムなどが知られている。
有機ポリマー難燃化おいては、燐酸エステル、三酸化アンチモン、臭素系、ハロゲン化合物などが知られている。特に化石燃料を原料とする有機ポリマーは、難燃化止まりでまだ不燃化には到っていない。
また、難燃性を与える為に、フィラーとして水酸化アルミニュウム・水酸化マグネシュウ化合物などを添加や後加工による場合にチタン、ジルコニュウム化合物などもある。Incombustibility of plant-derived wood, paper, and fibers is widely known. As chemicals effective for incombustibility, diammonium hydrogen phosphate, borax, boric acid, barium chloride and the like are known.
In the organic polymer flame retardant, phosphoric acid ester, antimony trioxide, bromine, halogen compound and the like are known. In particular, organic polymers that use fossil fuels as a raw material have not yet been made non-combustible because they have become non-flammable.
In addition, in order to impart flame retardancy, there are titanium, zirconium compounds, and the like when adding aluminum hydroxide / magnesium hydroxide compound as a filler or by post-processing.
前項記載の従来の不燃化剤、難燃化剤以外の新規の無機系不燃剤を見出すことにまず専念する。水溶性無機素材は一般的に有機ポリマー製品への浸透性に難があり、無機と有機の融合によって不燃剤に浸透拡散性機能を付与する技術操作を基礎研究課題として吸湿性のある化学繊維素材、連続気泡フォーム材に不燃性有効組成を浸透結合させる後加工法。
表面浸透によって不燃化が可能な新規不燃剤であれば溶媒或いは粉体化操作によってプラスチック製造時に共重合或いは練り込みによる改質も可能となる。また、産業廃棄物に不燃化処理した有機物を焼成させた後にこの炭化物を圧縮成形体とすると比重の軽さを活かした不燃性のＣＣコンポジット超耐熱素材が産廃物から新素材が誕生する。First, we will concentrate on finding new inorganic flame retardants other than the conventional flame retardants and flame retardants described in the previous section. Water-soluble inorganic materials generally have difficulty in penetrating organic polymer products, and hygroscopic chemical fiber materials are used as a basic research subject to technical operations that impart infiltration and diffusive functions to flame retardants by the fusion of inorganic and organic materials. A post-processing method in which an incombustible active composition is osmotically bonded to an open-cell foam material.
If it is a new incombustible agent which can be incombustible by surface permeation, it can be modified by copolymerization or kneading at the time of plastic production by a solvent or powdering operation. In addition, when an incombustible organic material is baked into industrial waste and this carbide is used as a compression-molded product, a non-combustible CC composite super heat resistant material utilizing the lightness of specific gravity is born from the industrial waste.
本発明の不燃化にとって有効なポリ塩化アルミニュウムが新たに見出された。
ポリ塩化アルミニュウムは凝集性浄水剤であり、ＪＩＳ Ｋ１４７５−１９７８水道用ポリ塩化アルミニュウムであり、本発明不燃化の核となる素材である。
以下に改質主要材料を示す。
ポリ塩化アルミニュウム（ＰＡＣ）
エタノール製剤成分重量比
エタノール６７，８９部／乳酸ナトリュウム０，０２５部／精製水３２，０８５部
３、メチレンクロライド
不燃性改質に用いる主な基本的成分重量比組成を以下に示す。
（Ａ）不織布、連続気泡フォーム対応不燃性浸透改質剤の基本重量比組成（以下、不燃Ａと略称する）
不燃Ａ剤重量比組成
ＰＡＣ ５５〜６０部、エタノール製剤４５〜５０部、メチレンクロライド１〜１，５部を調合する。
不燃化する素材として、ビニロン不織布（日本バイリーン製）、ポリエステル不織布（東洋紡スパンボンド）、ポリエステル７０％綿３０％合繊、バックスキン層を有する革、連続気泡ウレタンフォーム（各社）、連続気泡ポリエチレンフォーム（三和化工オプセル）、汎用炭ボードを選定した。

Ａ−２、不燃化する試料を前記の不燃剤入り容器に４０秒から１分間程度浸漬する。
炭ボードのみ吸水性が高いため浸漬せず２回追いかけ刷毛塗りとした。
Ａ−３、浸漬完了後、浸透余剰分を絞り取り自然乾燥させる。（遠心分離、温風乾燥が工業的に好ましい）
試料選定した各試料の乾燥体は、ミクロバーナー法燃焼試験に不燃認定される状況にある。

Polyaluminum chloride is a cohesive water purifier, JIS K1475-1978 polyaluminum chloride for water supply, and is a material that becomes the core of the incombustibility of the present invention.
The main reforming materials are shown below.
Polyaluminum chloride (PAC)
Ethanol formulation component weight ratio Ethanol 67,89 parts / sodium lactate 0,025 parts / purified water 32,085 parts3, main basic component weight ratio composition used for methylene chloride nonflammability modification is shown below.
(A) Basic weight ratio composition of non-woven fabric and open-cell foam compatible non-flammable penetration modifier (hereinafter abbreviated as non-flammable A)
Incombustible A agent weight ratio composition PAC 55 - 60 parts, ethanol formulation 45-50 parts of methylene chloride 1 to 1,5 parts formulated.
As non-combustible materials, vinylon nonwoven fabric (made by Nippon Vilene), polyester nonwoven fabric (Toyobo Spunbond), polyester 70% cotton 30% synthetic fiber, leather with back skin layer, open cell urethane foam (each company), open cell polyethylene foam ( Sanwa Chemical Opcell) and general-purpose charcoal board were selected.
A-1 and an appropriate amount of non-combustible agent A are put into a suitable nonpolar container or stainless steel container.
A-2, the sample to be incombustible is immersed in the container containing the incombustible agent for about 40 seconds to 1 minute.
Since only the charcoal board has high water absorption, it was chased twice without being dipped.
A-3, After the completion of immersion, the permeation surplus is squeezed out and dried naturally. (Centrifuge and hot air drying are industrially preferred)
The dry body of each selected sample is in a state where it is certified as non-combustible in the micro burner method combustion test.
Fire irradiation 30 seconds twice continuously, does not ignite, does not heat melt, and partially carbonizes. Within carbonized part 3-7mm. (Incombustible certification is within 25mm) (Claim 2)
The combustion test of the charcoal board is a gas burner direct flame irradiation at 1300 ° C for 20 minutes. It turns red, but no combustion ignition smoke is generated, and there is no damage, no collapse, no surface change, and it can be judged that it has extremely high heat resistance. The heat resistance increased from the first time when flame burner irradiation (20 minutes) was applied again to the same location, and a heat resistance performance far exceeding 1500 ° C. was born. This phenomenon is an approximate process similar to that in the production of carbon fiber, and since the present invention is a carbonization technique including a non-combustible agent, it is considered that non-combustibility and heat resistance have been dramatically improved. (Claim 3)
Incombustible B agent weight ratio composition (hereinafter referred to as incombustible B agent)
Prepare 35-40 parts PAC and 60-65 parts water.
Copy paper, tissue paper, cotton, silk, and hemp were selected as nonflammable materials.
Similarly to the above, after immersing in an appropriate container for about 10 seconds, the permeation surplus is squeezed and dried.
The test result of the micro burner method showed that non-combustible B also had the same effect as non-combustible A, but only paper was a thin layer, so the carbonized range was a wide range of 18 mm compared to the natural fiber average of 5 mm It is. (Claim 1)
ＰＡＣとエタノールと水分、極めて微量に含まれる乳酸ナトリュウムを含有する相乗作用で微量のメチレンクロライドも分離する事無く完全相溶する。
浸透定着するメカニズムは、主にエタノール溶媒とＰＡＣによる膨潤浸透効果（連続気泡ウレタンフォーム）浸透効果（吸湿性表面化学繊維、合繊、天然繊維、革、紙など）軟質連続気泡ポリエチレンフォームは柔軟セル構造と表面層近傍の素材内部に無機高分子であるＰＡＣ成分が溶媒と共に浸透して定着する。
ＰＡＣは、主成分として酸化アルミニュウム、硫酸イオンを含む塩基性で有り可燃性物質を含まず燃焼せず、また、燃焼の恐れのあるエタノールはメチレンクロライド、水分と共に気化する。すなわち無機高分子ポリマーとして酸化アルミニュウム不燃性有効成分のみが浸透定着する効果で燃焼に伴うラジカルの連鎖反応が停止する。
更に、前記不燃性処理剤を浸透加工させた素材を焼成する或いは炭の様に半焼成された状態の素材に不燃性処理剤を浸透加工する操作から生まれる耐熱新素材は一度不燃炭化した高性能のカーボン材であり、超高温以外では焼成不能な不燃炭素に構造変化したものと推察される。PAC, ethanol, moisture, and sodium lactate contained in a very small amount are synergistically compatible with each other without separating a very small amount of methylene chloride.
Penetration mechanism is mainly the swelling penetration effect by ethanol solvent and PAC (open cell urethane foam) penetration effect (hygroscopic surface chemical fiber, synthetic fiber, natural fiber, leather, paper, etc.) Soft open cell polyethylene foam has flexible cell structure The PAC component, which is an inorganic polymer, penetrates with the solvent into the material near the surface layer and is fixed.
PAC is a basic substance containing aluminum oxide and sulfate ions as main components, does not contain flammable substances, does not burn, and ethanol that may burn is vaporized together with methylene chloride and moisture. That is, the radical chain reaction accompanying combustion is stopped by the effect that only the aluminum oxide nonflammable active ingredient penetrates and fixes as an inorganic polymer polymer.
Furthermore, the new heat-resistant material born from the operation of calcination of the material infiltrated with the non-combustible treatment agent or the infiltration treatment of the non-combustible treatment agent into the semi-fired material such as charcoal is a high-performance carbonized once non-combustible carbonized. It is presumed that the carbon material has undergone a structural change to non-combustible carbon that cannot be fired except at ultra-high temperatures.

数多くの実験例において、不燃Ａ剤の各成分重量比組成は代表的な数値である。実施例のごとく素材の質感を変化させずに不燃性能を与えることが可能で懸念されるＰＡＣの基本的に持つ再湿性もエタノール、メチレンクロライド配合効果で質感の経時変化を抑制する効果も生まれた。
また、本発明の不燃化処理を加工したものは、総て耐熱性が向上する。In many experimental examples, the weight ratio composition of each component of the incombustible agent A is a representative numerical value. As in the examples, it was possible to give nonflammability performance without changing the texture of the material, and the rewetting property of PAC, which is a concern, was also created, and the effect of suppressing change in texture over time was also born by the effect of blending ethanol and methylene chloride. .
In addition, the heat resistance of all the non-combustible treatments of the present invention is improved.
不燃Ａ剤の場合、メチレンクロライドを僅か１，５％以内で配合している為、環境への影響は極めて僅か、他の溶媒に置換しても良いが、素材によって溶解性パラメーターＳＰ値を参考にした浸透性溶媒の選定が必要になる。In the case of non-combustible agent A, since methylene chloride is blended in only 1.5% or less, the impact on the environment is very slight, and it may be replaced with another solvent. It is necessary to select a permeable solvent.
第３実施例の不燃化させた炭ボードの炭材は一度半焼成したものであり、そのものに本発明の不燃Ａ剤加工を施す簡易な操作で極めて耐熱性が高く１，５００℃〜を超える優れた耐熱性が生まれた。同様な超耐熱現象は、活性炭や炭以外の不燃処理し実験に使用した各種炭化物圧縮成形体にも見られる。具体的には植物由来のでんぷん類、炭水化物、植物系たんぱく質、セルロース、動物性たんぱく質、膠質、各種天然繊維、各種化学繊維、連続気泡ウレタンフォーム、連続気泡ポリエチレンフォームなど。すなわち不燃処理して炭化過程を経た物質は防融、不燃、超耐熱性素材である。産業廃棄物や一般家庭から混載排出される布団、絨毯、カーテンや生ゴミも総てケミカルリサイクルとして不燃材や耐熱素材に生まれ変わる。また、高野豆腐なども不燃断熱パネル化も有効です。

Specifically, starches derived from plants, carbohydrates, plant proteins, cellulose, animal protein, glue, various natural fibers, various chemical fibers, open cell urethane foam, open cell polyethylene foam and the like. That is, a substance that has been subjected to non-flammable treatment and carbonized is a non-fusible, non-flammable, super heat-resistant material. Industrial waste and futons, carpets, curtains and garbage that are mixed and discharged from households are all reborn as non-combustible and heat-resistant materials as chemical recycling.

生分解性不燃耐熱断熱ボード、繊維屑を応用した鉄骨耐火被覆材、石綿代替等。The incombustible agent B of the present invention is in the form of an aqueous solution, but it can be pulverized by an operation of agglomeration and drying from the gelation process by adding diammonium hydrogen phosphate, borax, or borate alone or in combination. Nonflammable gels and processed powders produced by this operation are also effective as an incombustible and heat resistant modifier for organic polymers, starch and carbohydrates. Examples that are applied to starch and applied as biodegradable non-combustible binders include non-combustible glue bonding, non-combustible wood powder board molding, non-combustible cork molding, non-combustible old newspaper paper molding, non-combustible coffee coffee molding, non-combustible It has been confirmed that it is effective as a variety of nonflammable binders such as rice husk moldings and lint moldings.

防災衣料、レーサー服、消防服、スーパー繊維の不燃化など。It is considered that it is possible to improve flame retardancy or incombustibility and heat resistance by a technical means of compatibilizing the modified flame retardant of the present invention with fibers synthesized by liquid crystal spinning, melt spinning, or the like. In addition, application of post-processing for fixing can be expected to be applied in various ways such as a technique for kneading, melting and spinning ash fine particles carbonized by incombustibility.

燃焼で析出されるものは炭化物或いは灰分であるまた、燃焼に伴って発生する分解ガス有害成分が空気中に放散する現象は極めて少なく、大気汚染を招かず環境にとって好ましい。
不燃原料であるポリ塩化アルミニュウムは水道用の安全性の高い原料であり且つ安価。コスト優位性は、従来に比べ、原料の節約に加え、資源再生再利用という特長から廃棄物発生を最小限に抑えその結果、環境負荷、廃棄物処理埋め立て処理費用を著しく下げる。What is deposited by combustion is carbide or ash. Moreover, the phenomenon that harmful components of the decomposition gas generated by combustion are diffused into the air is extremely small, and it is preferable for the environment without causing air pollution.
Polyaluminum chloride, an incombustible raw material, is a highly safe raw material for water supply and is inexpensive. Compared with the conventional technology, the cost advantage is not only the saving of raw materials but also the feature of resource recycling and reuse, minimizing the generation of waste, resulting in a significant reduction in environmental impact and waste disposal landfill costs.
最近プラスチック製品の再生利用について多くの関心が寄せられている。製造過程で廃棄物の再生利用に比べ最終消費廃棄物は、更に多くの困難があり、回収、分類、分離の過程において廃棄物は様々な物質で汚染されている簡単容易な方法では防げず問題は未解決である。本発明の不燃処理方法を組み込んだ焼却炉プラントシステムが稼動すれば、焼却炉の損傷もなく焼成によって炭化或いは灰分になったものは総て不燃耐熱カーボン素材として再生資源となる。
また、従来システムで焼却炉、溶融炉などから埋め立て処分される焼却灰なども本発明不燃剤処理によって不燃耐熱素材として有効活用が図れる。Recently there has been much interest in recycling plastic products. In the manufacturing process, the final consumption waste is more difficult than the recycling of waste, and in the process of recovery, classification and separation, the waste is contaminated with various substances. Is unresolved. If the incinerator plant system incorporating the incombustible treatment method of the present invention is operated, any carbonized or ashed material by calcination without damage to the incinerator becomes a recycled resource as a noncombustible heat-resistant carbon material.
Moreover, incineration ash and the like that are disposed of in landfills from incinerators, melting furnaces, and the like in the conventional system can be effectively used as non-combustible heat-resistant materials by the incombustible treatment of the present invention.
本発明によって不燃化した素材は、総て従来の耐熱性数値を超える耐熱性が付与される。
天然繊維である絹の場合は通常１５０℃で分解するが、不燃剤処理したものは３００℃に十分に耐える素材となる。熱可塑性ポリマーから成る製品であるポリエステル繊維なども同様に基本的にもつ耐熱性を少なくとも３０〜８０％超える耐熱性が生まれる。しかも熱による収縮現象もなく溶融もしない。All the materials incombustible according to the present invention are given heat resistance exceeding conventional heat resistance values.
Silk, which is a natural fiber, usually decomposes at 150 ° C., but a material treated with a flame retardant is a material that can sufficiently withstand 300 ° C. Similarly, polyester fiber, which is a product made of a thermoplastic polymer, also has a heat resistance that is at least 30 to 80% higher than the basic heat resistance. Moreover, it does not shrink due to heat and does not melt.
