Description
本発明は、防炎剤に関し、とくに一般人において容易に取り扱い可能な建材用防炎剤に関する。 The present invention relates to a flameproofing agent, and particularly to a flameproofing agent for building materials that can be easily handled by ordinary people.
我が国は木竹材からなる建物が多いため火災が後を絶たない。火災が発生すると人的物的に多大の損失が生ずるため、その有効な防止対策が求められる。
従来は防炎建材として石膏ボートが用いられてきた。しかしながら、石膏ボートは切削や釘打ち等、加工が困難であった。
Because there are many buildings made of wood and bamboo in Japan, there is no end to fire. When a fire breaks out, a great amount of human and material loss occurs, so effective prevention measures are required.
Conventionally, gypsum boats have been used as flameproof building materials. However, gypsum boats were difficult to process such as cutting and nailing.
一方、多用されている木材や竹材といった建材は、厚みがあるため、防炎剤が十分に浸透し難いという欠点があった。従来型の防炎剤を木材や竹材の如き建材に適用し、浸漬法により浸透させようとしても結局徒労に終わっていた。 On the other hand, building materials such as wood and bamboo, which are frequently used, have a drawback that the flameproofing agent is not sufficiently penetrated because of its thickness. Even if conventional flameproofing agents were applied to building materials such as wood and bamboo, and tried to penetrate by the dipping method, it ended up being hard work.
本出願人はかつて浸透力を強化した防炎剤を開発し世上に問い、特許査定を得た。しかし、この防炎剤もカーテン等の繊維製品には対応できたが、繊維製品に比し比較にならない程の厚さと密な構造を有する木材や竹材の如き建材には浸透力が十分でなく、長期の経時劣化に対応することができなかった。建材は雨風や天日に曝されるため、防炎剤が十分に浸透されていないと長年月の間に経時劣化され、燃焼の防止をすることができなくなるからである。 The applicant once developed a flameproofing agent with enhanced penetrating power, asked the world, and obtained a patent. However, this flame retardant could also be applied to textile products such as curtains, but the permeability is not sufficient for building materials such as wood and bamboo, which have a thickness and dense structure that are incomparable compared to textile products. , Could not cope with long-term deterioration over time. This is because the building materials are exposed to rain and wind and the sun, so if the flameproofing agent is not sufficiently infiltrated, it will deteriorate over time and will not be able to prevent combustion.
本願発明は、上記背景により、特許文献１による技術の開発後も３０有余年研究し開発した結果の賜であり、漸く十分な浸透力を得、木材や竹材の如き建材にも適用することができる建材用防炎剤としたものである。
即ち、本願発明は木材や竹材の如き建材につき、加圧、加温の調節をすることなく、常温常圧化にて一般人が容易に取り扱うことができる建材用防炎剤を供することを目的とする。

さらに、本願発明による建材用防炎剤にて加工される対象物は通常の建材であるから、切削や釘打ち等、加工が容易であるという効果がある。 Furthermore, since the object processed with the flameproofing agent for building materials according to the present invention is a normal building material, there is an effect that processing such as cutting and nailing is easy.
次に、本発明による建材用防炎剤を実施例に基づいて詳しく説明する。 Next, the flameproofing agent for building materials according to the present invention will be described in detail based on examples.
防炎剤は硫黄、リン及び窒素化合物を主成分とする比重１．２の液体からなる。本例では、ニッカファイノンＳ−２００（福井県福井市文京４丁目２３番１号、日華化学株式会社製造）を使用した。 The flameproofing agent is composed of a liquid having a specific gravity of 1.2 containing sulfur, phosphorus and nitrogen compounds as main components. In this example, Nikkafinon S-200 (Bunkyo 4-23-1, Fukui City, Fukui Prefecture, manufactured by Nikka Chemical Co., Ltd.) was used.
親水性揮発性浸透剤としてはメタノールを使用した。親水性揮発性浸透剤としては、この外、エタノール、アセトン、エチルメチルケトン、テトラヒドロフラン等が使用可能である。 Methanol was used as the hydrophilic volatile penetrant. In addition, ethanol, acetone, ethyl methyl ketone, tetrahydrofuran and the like can be used as the hydrophilic volatile penetrant.
微量成分としてはジエチレングリコールモノブチエーテル（別名ブチルセロソルブ）を水にて４％に希釈して使用した。 As a trace component, diethylene glycol monobutyether (also called butyl cellosolve) was diluted to 4% with water and used.
本実施例による防炎剤は水にて希釈攪拌された後、メタノールが添加され攪拌される。各成分の使用量は防炎剤２５０容量部、メタノール１１０乃至９０容量部、水６００乃至６２０容量部であり、好適には、防炎剤２５０容量部、メタノール１００容量部、ジエチレングリコールモノブチエーテル４０容量部、水６５０容量部である。メタノールの場合、防炎剤２５０容量部に対し１１０容量部を超えると毒性が強くなるので不可となり、９０容量部を下回ると防炎剤を浸透せしめる作用が不良となる。 The flame retardant according to this example is diluted and stirred with water, and then methanol is added and stirred. The amount of each component used is 250 parts by volume of flame retardant, 110 to 90 parts by volume of methanol, and 600 to 620 parts by volume of water, preferably 250 parts by volume of flame retardant, 100 parts by volume of methanol, The capacity part is 650 parts by volume of water. In the case of methanol, if the amount exceeds 110 parts by volume with respect to 250 parts by volume of the flameproofing agent, it becomes impossible because the toxicity becomes strong.
容器に入れた上記組成の建材用防炎剤に、木材や竹材の如き建材を浸漬し、建材に防炎成分を十分に浸透させる。その後３日乃至４日間乾燥させ、完全に乾燥したら建材対象物にクロス材を貼付する等して、表面をコーティングする。古民家などからでる中古の建材の場合、表面にある小孔にスプレーノズルを挿入し、実施の形態による建材用防炎剤を噴霧し、乾燥後表面をコーティングする。 A building material such as wood or bamboo is immersed in the flameproofing agent for building material having the above composition in a container, and the flameproofing component is sufficiently infiltrated into the building material. Then, it is dried for 3 to 4 days, and when it is completely dried, the surface is coated by applying a cloth material to the building material object. In the case of a used building material from an old private house or the like, a spray nozzle is inserted into a small hole on the surface, the flameproofing agent for building material according to the embodiment is sprayed, and the surface is coated after drying.
木材や竹材は高密度でありヤニや油分を含むため、微量成分ジエチレングリコールモノブチエーテルを含有しない防炎剤（特許文献１に示す防炎剤）であると、浸透力にばらつきがでる。しかしながら、本願発明による防炎剤は微量成分ジエチレングリコールモノブチエーテルを含有するため、強い浸透力により瞬時の浸透が可能であり、浸透力にばらつきがでない、よって高厚の木材や竹材でも製品の不良率が実質上ない。 Since wood and bamboo have a high density and contain spear and oil, a penetrating power varies if the flameproofing agent does not contain a trace component diethylene glycol monobutyether (a flameproofing agent shown in Patent Document 1). However, since the flameproofing agent according to the present invention contains a trace amount of diethylene glycol monobutyether, instant penetration is possible with strong penetration, and there is no variation in penetration, so even with thick wood and bamboo, the product is defective. There is virtually no rate.
公益財団法人日本防炎協会の定義によると、防炎とは、燃えにくい性能を示し、小さな火種に接しても容易に燃え上らず、もし着火しても際限なく燃え広がらないこと、即ち、自己消化性（自ら延焼拡大を停止する性能）があることをいう。そして自己消化性は残炎時間、残じん時間、炭化面積がどの位であるかにより評価される（根拠法令：消防法施行規則第４条の３第３項から第7項まで）。 According to the definition of the Japan Flame Retardant Association, flame proofing means that it does not burn easily when exposed to small fire types, and does not spread indefinitely even if ignited. It means that there is self-digestibility (the ability to stop the spread of fire spread). And self-digestibility is evaluated by how long afterflame time, afterglow time, and carbonization area (basis law: Article 4-3, Paragraph 3 to Paragraph 7 of Fire Service Enforcement Regulations).
合板の場合、夫々、残炎時間１０秒以下、残じん時間３０秒以下、炭化面積５０?以下であることが防炎性能ありと評価される基準値である。 In the case of plywood, the reference values for evaluating the flameproof performance are that the afterflame time is 10 seconds or less, the residual time is 30 seconds or less, and the carbonized area is 50? Or less.
防炎性能試験は、４５メッケルバーナー法と呼ばれる試験法により試験される。試験は、公益財団法人日本防炎協会の防炎性能試験基準に定める方法に従い、４５°傾斜して置かれた供試体に炎長６５ｍｍの火源を加熱時間2分間当てて行われた。供試体には本願発明に係る防炎剤が含浸加工されている。結果は、表１の通りである。 The flameproof performance test is performed by a test method called a 45 Meckel burner method. The test was carried out by applying a fire source with a flame length of 65 mm to a test piece placed at an angle of 45 ° and a heating time of 2 minutes in accordance with the method defined in the flameproof performance test standard of the Japan Flame Retardant Association. The specimen is impregnated with the flameproofing agent according to the present invention. The results are shown in Table 1.
表１
Table 1
表１中、残炎時間（秒）「１」とあるのは、バーナの火を消すと瞬間的に火が消え、１秒以下を計測することできなかったためであり、「1秒以下」を意味する。また残じん時間（秒）「１」とあるのもバーナの火を消すと瞬間的に火が消え、残じんも殆どなく、１秒以下を計測することできなかったためであり、「1秒以下」を意味する。なお、合板に関しては、接着剤が防炎効果を妨げるため、高厚の合板程防炎効果を増す傾向があった。 In Table 1, the after flame time (seconds) is “1” because when the burner was extinguished, the fire disappeared instantaneously and it was impossible to measure less than 1 second. means. Also, the remaining dust time (seconds) is "1" because when the burner was extinguished, the fire went out instantaneously and there was almost no residual dust, and it was impossible to measure less than 1 second. "Means. As for the plywood, since the adhesive hinders the flameproofing effect, the thicker plywood tended to increase the flameproofing effect.
表１より、本願発明に係る防炎剤が含浸された供試対象物は、いずれの場合も発炎には至らず、炭化されるのみである。残炎時間はいずれも１０秒以下であり、残じん時間もいずれも基準値３０秒以下を遥かに下回っており、炭化面積もいずれも基準値５０?以下を遥かに下回っている。なお、火源に対して９０°の直交面としてみても、２分加熱（上記防炎性能試験基準）で発炎には至らなかった。よって本願発明に係る防炎剤が含浸された建材の防炎効果は顕著である。 From Table 1, the test object impregnated with the flameproofing agent according to the present invention does not lead to flame in any case and is only carbonized. The afterflame times are all 10 seconds or less, the residual dust times are all well below the reference value of 30 seconds or less, and the carbonization areas are all well below the reference value of 50? Or less. In addition, even when viewed as a plane orthogonal to the fire source at 90 °, no flame was reached by heating for 2 minutes (the flameproof performance test standard). Therefore, the flameproofing effect of the building material impregnated with the flameproofing agent according to the present invention is remarkable.
加えて本願発明による建材用防炎剤は、危険性のあるメタノール等の親水性揮発性浸透剤及びジエチレングリコールモノブチエーテルが十分に希釈されているため、加圧、加温の調節をすることなく、常温常圧化にて一般人が容易に取り扱うことができる。 In addition, the flame retardant for building materials according to the present invention is sufficiently diluted with dangerous volatile penetrants such as methanol and diethylene glycol monobutyether, so without adjusting the pressure and heating. It can be easily handled by ordinary people at room temperature and normal pressure.
また建材対象物の表面がコーティングされているので、建材対象物に浸透された主成分が雨水等により希釈されず、また天日に曝されて劣化されるのを防止する。出願人の実験によれば、本願発明による建材用防炎剤にて加工処理された建材は防炎効果が３１年間持続され、現在も持続中である。 Further, since the surface of the building material object is coated, the main component that has penetrated into the building material object is not diluted with rainwater or the like, and is prevented from being deteriorated by being exposed to the sun. According to the applicant's experiment, the building material processed with the flameproofing agent for building material according to the present invention has a flameproofing effect for 31 years and is still ongoing.
このように本願発明による建材用防炎剤に強力な浸透力があるのは、それ自体浸透力が強いメタノール等親水性揮発性浸透剤に微量成分ジエチレングリコールモノブチエーテルを僅かに加えたことにより、浸透力が格段に強化されたためであると考えられる。かかる成分割合は出願人による永年の試行錯誤の結果、漸うたどり着いたものである。 As described above, the flameproofing agent for building materials according to the present invention has a strong penetrating power because a slight amount of diethylene glycol monobutyether is added to a hydrophilic volatile penetrating agent such as methanol having a strong penetrating power. This is thought to be because the penetrating power was remarkably strengthened. Such component ratios have gradually arrived as a result of many years of trial and error by the applicant.
本願発明による建材用防炎剤は、上記実施例に制限されるものではない。例えば、適用される建材の種類は任意であり、竹材などにも適用することができる。また適用される建材の厚さも任意であって、表１に挙げた供試体は一例に過ぎない。また対象物への本剤の付与は建材の種類に対応して付与することができ、例えば塗布にて付与してもよい。さらに本願発明による建材用防炎剤の付与後に行う表面へのコーティングも適宜のものでよい。 The flameproofing agent for building materials according to the present invention is not limited to the above examples. For example, the type of building material to be applied is arbitrary, and it can be applied to bamboo and the like.
