Description
本発明は、有機質材料を難燃化又は不燃化する難燃化コーティング剤組成物並びにそれを用いた難燃化有機質材料及び難燃化木材に関するものである。 TECHNICAL FIELD The present invention relates to a flame retardant coating agent composition that makes an organic material flame retardant or flame retardant, and a flame retardant organic material and flame retardant wood using the same.
従来、有機質材料の表面に塗付され、該有機質材料を難燃化又は不燃化する浸透性難燃化剤としては、水1000mLに、少なくとも、50〜250gのリン酸水素二アンモニウム((NH4)2HPO4)、50〜250gの二リン酸(H4P2O7)、5〜30gの水酸化アルミニウム(Al(OH)3)、3〜15gのコロイド状シリカ、及び10〜50gのセメント上清水を添加することにより得られる木質材料処理組成物、この組成物を含浸させる(例えば、特許文献1参照。)、炭酸ジルコニウムアンモニウムを二酸化ジルコニウム換算で2〜40重量%、水溶性リン酸塩を2〜40重量%含有する水溶液(例えば、特許文献2参照。)等があった。
また、難燃化又は不燃化するコーティング剤組成物としては、主成分として硫酸塩,炭酸塩,リン酸塩,珪酸塩,硝酸塩,塩化物(塩はNa,K,NH4,Ca,Mg,Al、並びにスルファミン酸塩,グリコール酸塩,酒石酸塩,アジピン酸塩,乳酸塩,グルコン酸塩,ヒドロキシカルボン酸塩,サリチル酸塩,コハク酸塩,重硫酸塩(K,NH4,Na,MEA,DEA,TEA,MIPA,Mg)と併用した混合物)に、副成分として水溶性界面活性剤の2種以上の成分をバランスよく水溶液(ソリューション)とし、必要により第三成分として多価アルコールを含ませ、pHを中性〜弱アルカリ性(6〜10)にコントロールした(例えば、特許文献3参照。)等があった。
Conventionally, as a permeable flame retardant that is applied to the surface of an organic material to make the organic material flame-retardant or non-flammable, at least 50 to 250 g of diammonium hydrogen phosphate ((NH 4)) in 1000 mL of water. 2 HPO 4 ), 50-250 g diphosphoric acid (H 4 P 2 O 7 ), 5-30 g aluminum hydroxide (Al (OH) 3 ), 3-15 g colloidal silica, and 10-50 g cement. Woody material treatment composition obtained by adding supernatant water, impregnated with this composition (see, for example, Patent Document 1), 2-40% by weight of zirconium carbonate in terms of zirconium dioxide, water-soluble phosphate There is an aqueous solution containing 2 to 40% by weight (for example, see Patent Document 2).
Moreover, as a flame retardant or incombustible coating agent composition, sulfate, carbonate, phosphate, silicate, nitrate, chloride (salts are Na, K, NH 4 , Ca, Mg, Al and sulfamate, glycolate, tartrate, adipate, lactate, gluconate, hydroxycarboxylate, salicylate, succinate, bisulfate (K, NH4, Na, MEA, DEA) , TEA, MIPA, Mg) in combination with two or more components of a water-soluble surfactant as an accessory component in a well-balanced aqueous solution (solution), and if necessary, a polyhydric alcohol as a third component.

本発明の難燃化コーティング剤組成物はケイ酸カリウムと酸化カリウムとが含有されており、有機質材料に塗付することによって該有機質材料を難燃化又は不燃化する。
前記難燃化コーティング剤組成物の組成は例えば、以下のようなものである。
コーティング剤組成物の組成例:ケイ酸カリウム100質量部、酸化カリウム45質量部、コーティング剤組成物希釈剤としての水340質量部、消泡剤0.2質量部、増粘剤としてのキサンタンガム2質量部、凍結防止剤としてのプロピレングリコール2質量部。

Hereinafter, embodiments embodying the present invention will be described.
The flame retardant coating agent composition of the present invention contains potassium silicate and potassium oxide, and makes the organic material flame retardant or incombustible by applying it to the organic material.
The composition of the flame retardant coating agent composition is, for example, as follows.
Composition example of coating agent composition: 100 parts by mass of potassium silicate, 45 parts by mass of potassium oxide, 340 parts by mass of water as a diluent for coating agent, 0.2 parts by mass of antifoaming agent, xanthan gum 2 as a thickener 2 parts by mass of propylene glycol as an antifreezing agent.
Examples of the organic material include wood such as cedar, cypress, beech, pine, and paulownia, plastic such as carbonate resin, styrene resin, melamine resin, acrylic resin, and phenol resin, paper, and cloth.
前記難燃化又は不燃化とは塗付される有機質材料を燃えにくく又は燃えなくすることであるが、特に説明がない限り、建築基準法に規定されている難燃材料、準不燃材料、不燃材料の発熱性試験に合格することをいい、具体的には、ISO 5660−Fire test−Reaction tofiresurasshu Part1: Heatrelease(コーンカロリーメーター)に規定されている発熱性試験によって難燃材料にあっては試験開始後5分間、準不燃材料にあっては試験開始後10分間、不燃材料にあっては試験開始後20分間の発熱量が8MJ/m2以下であることをいう。 The above-mentioned flame retardant or non-flammable means to make the coated organic material difficult or non-combustible. Unless otherwise specified, the flame retardant material, quasi-incombustible material, non-combustible material specified in the Building Standard Law. This refers to passing the exothermic test of the material. Specifically, the test is performed for the flame-retardant material by the exothermic test specified in ISO 5660-Fire test-Reaction to fire relief Part 1: Heat release (cone calorimeter). It means that the calorific value is 8 MJ / m 2 or less for 5 minutes after the start, 10 minutes for the semi-incombustible material after the start of the test, and 20 minutes for the non-combustible material after the test starts.
前記ケイ酸カリウム100質量部に対する酸化カリウムの含有量は好ましくは25〜65質量部であり、より好ましくは35〜55質量部であり、最も好ましくは39〜49である。この範囲にあるとき、有機質材料に難燃化コーティング剤組成物による塗膜(以下、「難燃塗膜」という。)を形成した場合の難燃化又は不燃化に優れるとともに難燃塗膜の透明性に優れる。ケイ酸カリウム100質量部に対する酸化カリウムの含有量が25質量部未満の場合には、難燃化又は不燃化が十分でない。逆にケイ酸カリウム100質量部に対する酸化カリウムの含有量が65質量部を超える場合にも難燃化又は不燃化が十分でないとともに難燃塗膜の形成に際してひび割れが生じやすい。 The content of potassium oxide with respect to 100 parts by mass of potassium silicate is preferably 25 to 65 parts by mass, more preferably 35 to 55 parts by mass, and most preferably 39 to 49 parts. When it is in this range, it is excellent in flame retardancy or incombustibility when a coating film (hereinafter referred to as “flame retardant coating film”) is formed on the organic material with the flame retardant coating agent composition, and the flame retardant coating film Excellent transparency. When the content of potassium oxide with respect to 100 parts by mass of potassium silicate is less than 25 parts by mass, flame retardancy or incombustibility is not sufficient. On the contrary, when the content of potassium oxide with respect to 100 parts by mass of potassium silicate exceeds 65 parts by mass, flame retardancy or incombustibility is not sufficient and cracking tends to occur during formation of the flame retardant coating film.
前記難燃塗膜が透明であることにより、被塗物の意匠をそのまま視認することができる。
前記増粘剤は多糖類を用いることが好ましい。増粘剤として多糖類を用いることにより、ケイ酸カリウムと酸化カリウムとを含有する水溶液を適度に増粘させることができる。多糖類としては例えば、セルロース、カルボキシメチルセルロース、ヒドロキシエチルセルロース等のセルロース類、キチン、キサンタンガム、デンプン、グリコーゲン、アガロース、ペクチン、カラギーナン等が挙げられる。これらのうち、キサンタンガムを用いることが好ましい。キサンタンガムを用いることにより、ケイ酸カリウムと酸化カリウムとを含有する水溶液をより効果的に増粘させることができるとともに、増粘後の粘度安定性に優れる。
When the flame retardant coating film is transparent, the design of the object to be coated can be visually recognized as it is.
The thickener is preferably a polysaccharide. By using a polysaccharide as a thickener, an aqueous solution containing potassium silicate and potassium oxide can be appropriately thickened. Examples of the polysaccharide include celluloses such as cellulose, carboxymethyl cellulose, and hydroxyethyl cellulose, chitin, xanthan gum, starch, glycogen, agarose, pectin, and carrageenan. Of these, xanthan gum is preferably used. By using xanthan gum, an aqueous solution containing potassium silicate and potassium oxide can be more effectively thickened, and the viscosity stability after thickening is excellent.
前記増粘剤の使用量はケイ酸カリウムと酸化カリウムとの合計質量100質量部に対して、好ましくは0.01〜2.5質量部、より好ましくは0.02〜0.1質量部、最も好ましくは0.025〜0.05質量部である。この範囲にあるとき、有機質材料に難燃塗膜を形成した場合の難燃化又は不燃化に優れるとともに、難燃化コーティング剤組成物に適度な粘性を与える。前記増粘剤の使用量がケイ酸カリウムと酸化カリウムとの合計質量100質量部に対して0.01質量部未満である場合には、増粘効果が少なく難燃化コーティング剤組成物を被塗物に塗付する際に十分な膜厚を確保できないおそれがある。逆に増粘剤の使用量がケイ酸カリウムと酸化カリウムとの合計質量100質量部に対して2.5質量部を超える場合には、火災時の燃焼熱により炭化して発熱するとともに、燃焼熱を吸収してしまうために難燃化又は不燃化が十分でないおそれがある。 The amount of the thickener used is preferably 0.01 to 2.5 parts by mass, more preferably 0.02 to 0.1 parts by mass, with respect to 100 parts by mass of the total mass of potassium silicate and potassium oxide. Most preferably, it is 0.025-0.05 mass part. When it is in this range, it is excellent in flame retardancy or incombustibility when a flame retardant coating film is formed on an organic material, and gives an appropriate viscosity to the flame retardant coating agent composition. When the amount of the thickener used is less than 0.01 parts by mass with respect to 100 parts by mass of the total mass of potassium silicate and potassium oxide, the thickening effect is small and the flame retardant coating agent composition is coated. There is a possibility that a sufficient film thickness cannot be secured when applied to the coating. Conversely, when the amount of thickener used exceeds 2.5 parts by mass with respect to 100 parts by mass of the total mass of potassium silicate and potassium oxide, the carbonization is generated by the heat of combustion at the time of the fire and heat is generated. Since heat is absorbed, there is a possibility that flame retardancy or incombustibility may not be sufficient.
前記コーティング剤組成物希釈剤は水、アルコール、その他の有機溶剤等、ケイ酸カリウム及び酸化カリウムを溶解することができるものであれば任意に用いることができる。
前記凍結防止剤は希釈剤として水を用いた場合に使用される。前記凍結防止剤はプロピレングリコールに限らず、水の凍結防止に効果のあるものであれば任意に用いることができる。例えば、エチレングリコール等が挙げられる。
The coating composition diluent can be arbitrarily used as long as it can dissolve potassium silicate and potassium oxide, such as water, alcohol, and other organic solvents.
The antifreezing agent is used when water is used as a diluent. The antifreezing agent is not limited to propylene glycol, and any antifreezing agent can be used as long as it is effective in preventing freezing of water. For example, ethylene glycol etc. are mentioned.
以上のように構成された難燃化コーティング剤組成物は以下のように使用される。
はじめに、有機質材料としての木材(スギ)の表面に難燃化コーティング剤組成物を塗付量2kg/m2で塗り付け、常温で16時間放置する。続いて、塩素化合成樹脂としての塩素化ポリオレフィン樹脂を塩素化合成樹脂希釈剤としてのトルエンで希釈した塩素化合成樹脂溶液を塗付量30g/m2で塗装して常温で16時間放置することにより、透明な塗膜が形成された難燃化有機質材料としての難燃化木材を得る。
前記難燃化木材が火災時の燃焼熱にさらされると、難燃化コーティング剤組成物は加熱によって発泡しガラス化することによって、被塗物である有機質材料への着火を抑制し、結果として発熱を抑制する。
The flame retardant coating agent composition configured as described above is used as follows.
First, a flame retardant coating composition is applied to the surface of wood (cedar) as an organic material at a coating amount of 2 kg / m 2 and left at room temperature for 16 hours. Subsequently, a chlorinated synthetic resin solution obtained by diluting a chlorinated polyolefin resin as a chlorinated synthetic resin with toluene as a chlorinated synthetic resin diluent is applied at a coating amount of 30 g / m 2 and left at room temperature for 16 hours. Thus, flame-retardant wood as a flame-retardant organic material having a transparent coating film formed thereon is obtained.
When the flame-retardant wood is exposed to the heat of combustion at the time of fire, the flame-retardant coating composition foams and vitrifies by heating, thereby suppressing ignition of the organic material that is the object to be coated. Suppresses fever.
前記難燃化コーティング剤組成物の塗付量は目的とする難燃化又は不燃化の度合いに応じて増減させる。例えば、5分間の発熱性試験で発熱量を8MJ/m2以下にするにはケイ酸カリウムと酸化カリウムとの合計質量が0.05〜0.25kg/m2、10分間の発熱性試験で発熱量を8MJ/m2以下にするには0.5〜1.5kg/m2、20分間の発熱性試験で発熱量を8MJ/m2以下にするには1.0〜2.0kg/m2になるよう難燃化コーティング剤組成物の塗付量を調節することが好ましい。
前記難燃化コーティング剤組成物の乾燥温度は常温に限らず、加熱して乾燥させることもできる。難燃化コーティング剤組成物を加熱乾燥させる場合の乾燥温度は好ましくは100℃以下、より好ましくは80℃以下である。この範囲にあるとき、乾燥後の塗膜が平滑で透明性を維持することができる。前記難燃化コーティング剤組成物の乾燥温度が100℃を超える場合には、乾燥後の塗膜の平滑性が十分でない。
The coating amount of the flame retardant coating agent composition is increased or decreased according to the target degree of flame retardancy or incombustibility. For example, to reduce the calorific value to 8 MJ / m 2 or less in a 5 minute exothermic test, the total mass of potassium silicate and potassium oxide is 0.05 to 0.25 kg / m 2 , and in a 10 minute exothermic test. the heating value of the heating value by the heating test of 0.5~1.5kg / m 2, 20 minutes to below 8 MJ / m 2 to below 8 MJ / m 2 is 1.0~2.0Kg / It is preferable to adjust the coating amount of the flame retardant coating agent composition so as to be m 2 .
The drying temperature of the flame retardant coating agent composition is not limited to room temperature, and may be dried by heating. The drying temperature when the flame retardant coating agent composition is heat-dried is preferably 100 ° C. or lower, more preferably 80 ° C. or lower. When it exists in this range, the coating film after drying can maintain smoothness and transparency. When the drying temperature of the flame retardant coating composition exceeds 100 ° C., the smoothness of the coating film after drying is not sufficient.
前記難燃化コーティング剤組成物の乾燥時間は、常温乾燥の場合は好ましくは10〜180時間、より好ましくは16〜80時間、最も好ましくは20〜70時間である。この範囲にあるとき、前記難燃化コーティング剤組成物の透明性及び耐久性に優れる。常温乾燥の場合の乾燥時間が10時間未満の場合には塗膜中の水分が多すぎて塩素化合成樹脂を塗付した後に水分が染み出てくるおそれがある。逆に常温乾燥の場合の乾燥時間が180時間を超える場合には乾燥が進みすぎて塗膜が収縮し、被塗物から剥がれて白く濁るおそれがある。 The drying time of the flame retardant coating agent composition is preferably 10 to 180 hours, more preferably 16 to 80 hours, and most preferably 20 to 70 hours when drying at room temperature. When in this range, the flame retardant coating composition is excellent in transparency and durability. In the case of drying at room temperature, if the drying time is less than 10 hours, the coating film has too much moisture, and moisture may ooze out after the chlorinated synthetic resin is applied. On the other hand, when the drying time in the room temperature drying exceeds 180 hours, the drying progresses too much and the coating film shrinks, and the coating film may be peeled off and become white.
前記塩素化合成樹脂を難燃塗膜の表面に積層させることにより、難燃塗膜を空気中の水分から保護することができる。
前記塩素化合成樹脂の塩素含有率は好ましくは20〜70質量%であり、より好ましくは30〜50質量%であり、最も好ましくは35〜45質量%である。この範囲にあるとき、難燃塗膜を空気中の水分から保護する性能(以下、「防湿性能」という。)に優れる。前記塩素化合成樹脂の塩素含有率が20質量%未満である場合には、防湿性能が十分でない。逆に70質量%を超える場合には塗膜としての柔軟性に欠けるため、クラック等の塗膜欠損を生じやすいため防湿性能が十分でない。
前記塩素化合成樹脂の塗付量は好ましくは3〜50g/m2、より好ましくは5〜15g/m2、最も好ましくは7〜10g/m2である。この範囲にあるとき、防湿性能に優れる。前記塩素化合成樹脂の塗付量が3g/m2未満の場合には防湿性能が十分でなく、逆に50g/m2を超える場合には発熱量が多すぎて発熱性試験に合格しないおそれがある。
By laminating the chlorinated synthetic resin on the surface of the flame retardant coating film, the flame retardant coating film can be protected from moisture in the air.
The chlorine content of the chlorinated synthetic resin is preferably 20 to 70% by mass, more preferably 30 to 50% by mass, and most preferably 35 to 45% by mass. When it is in this range, it is excellent in the performance of protecting the flame-retardant coating film from moisture in the air (hereinafter referred to as “moisture-proof performance”). When the chlorine content of the chlorinated synthetic resin is less than 20% by mass, the moisture-proof performance is not sufficient. On the other hand, when it exceeds 70% by mass, the flexibility as a coating film is insufficient, and coating film defects such as cracks are likely to occur, so that the moisture-proof performance is not sufficient.
The coating amount of the chlorinated synthetic resin is preferably 3 to 50 g / m 2 , more preferably 5 to 15 g / m 2 , and most preferably 7 to 10 g / m 2 . When it is in this range, the moisture-proof performance is excellent. When the coating amount of the chlorinated synthetic resin is less than 3 g / m 2 , the moisture-proof performance is not sufficient, and conversely, when it exceeds 50 g / m 2 , the heat generation amount is too high and the exothermic test may not pass. There is.

The chlorinated synthetic resin diluent is not limited to toluene, and can be arbitrarily set as long as it dissolves the chlorinated synthetic resin. For example, aromatic solvents such as xylene, and alcohols such as isopropyl alcohol, methanol, and ethanol can be used. Further, when the chlorinated synthetic resin is provided in the form of an emulsion, water may be used.
In addition to the antifoaming agent, additives used for ordinary coating agents can be used in the chlorinated synthetic resin solution. Examples include thickeners, dispersants, wetting agents, fibers, matting agents such as silica, and the like.
