【発明の属する技術分野】
本発明は、非ハロゲン系難燃性組成物に関し、さらに詳しくは、カーテン、カーペット等の繊維類若しくは木材等への表面コーティング、又は、植樹帯等への散布により難燃性を付与できる非ハロゲン系難燃性組成物に関するものである。
【0002】
【従来の技術】
難燃性組成物に用いる難燃剤は、プラスチック、ゴム、繊維、紙、木材等高分子材料を難燃化させるために使用される添加剤であり、高分子化合物に分散混合して使用する添加型の難燃剤として、ハロゲン系難燃剤、リン系難燃剤及び無機系難燃剤等がある。これらの中で、ハロゲン系難燃剤である臭素系難燃剤は、難燃性、樹脂特性及び経済性等のトータルバランスに優れているため、非常に多くの用途に大量に使用されてきた。
【0003】
しかしながら、近年において、ダイオキシンによる環境汚染の問題等への配慮から脱ハロゲン化のニーズが高まっており、非ハロゲン系の難燃剤を用いた難燃性組成物が用途別に多数開発されるに至っている。
【0004】
このような非ハロゲン系難燃性組成物の例として、常温にて固体である芳香族正リン酸エステル及び含窒素化合物を所定量配合してなる熱可塑性樹脂難燃性組成物(特許文献1参照)、リン系難燃剤と無機酸金属塩を所定量配合してなる熱可塑性樹脂及び熱硬化性樹脂難燃性組成物(特許文献2参照)、アクリル樹脂に対してポリリン酸アンモニウム、メラミン、多価アルコール及びシリカを所定量配合してなる、鋼材に耐火塗膜を形成する発泡型耐火塗料組成物(特許文献3参照)等がある。
【0005】
また、道路植樹帯及び公園等の屋外における難燃化に関し、非ハロゲン系難燃性組成物として水溶性アクリル樹脂を用い、この水溶性アクリル樹脂を敷設したバーク材(スギ、ヒノキ等の木質系の樹皮)の上から散布することにより難燃性を付与するもの(特許文献4参照)がある。

【発明が解決しようとする課題】
以上のような非ハロゲン系難燃性組成物は、各種材料の難燃化を目的とする点で共通するが、当然のことながら、使用される用途等により要求仕様が異なるものである。例えば、特許文献1における非ハロゲン系難燃性組成物は、熱可塑性樹脂の加工時の作業性、配合物の耐熱性・耐湿性、機械的強度及び難燃性向上を目的として発明されたものである。また、特許文献2における非ハロゲン系難燃性組成物は、熱可塑性樹脂及び熱硬化性樹脂における高い難燃効果の発揮を目的として発明されたものである。さらに、特許文献3における非ハロゲン系難燃性組成物は、火災時における塗膜のタレ、割れ、剥離・脱落等の抑制、鋼材に対する付着強度の向上及び均一発泡性の向上を目的として発明されたものである。さらにまた、特許文献4は、非ハロゲン系難燃性組成物として水溶性アクリル樹脂を選定し、この水溶性アクリル樹脂を敷設したバーク材の上から散布するものであり、難燃化及び防草化並びに施工の容易化及び景観性の向上等を目的として発明されたものである。
【0008】
特許文献1乃至3に記載された従来の非ハロゲン系難燃性組成物に係る発明は、前記各発明の目的を達するものであるが、本発明が着目する、カーテン、カーペット等の繊維類若しくは木材等への表面コーティング、又は、植樹帯等への散布により難燃性を付与できる非ハロゲン系難燃性組成物の組成を開示するものではない。
【0009】
また、特許文献4に記載された発明は、植樹帯等への散布により難燃性を付与する発明であるが、屋外での使用であり、継続的多量のたばこの投げ捨て等に対する長期間に亘る難燃性保持実現のニーズが強いものである。さらに、非ハロゲン系難燃性組成物自体の発明ではない。
【0010】
本発明は、以上のような状況を鑑みてなされたものであり、カーテン、カーペット等の繊維類若しくは木材等への表面コーティング、又は、植樹帯等への散布による難燃性付与に好適な非ハロゲン系難燃性組成物を得ることを目的とする。
【0011】
【課題を解決するための手段】
本発明に係る非ハロゲン系難燃性組成物は、前述の課題解決のため、リン酸アンモニウム塩類(重合塩も含む)水溶液と、リン酸エステル類と、樹脂水性エマルジョンとを成分とし、前記リン酸アンモニウム塩類を全成分の総重量に対して1重量%以上配合し、前記リン酸エステル類を前記樹脂水性エマルジョンのポリマー成分の重量に対して4重量%乃至100重量%配合してなるものである。
【0012】
ここで、前記リン酸エステル類を前記樹脂水性エマルジョンのポリマー成分の重量に対して15重量%以上配合すると好ましい。
【0013】
【発明の実施の形態】
本発明に係る非ハロゲン系難燃性組成物に用いるリン酸アンモニウム塩類(重合塩も含む)は、リン酸二水素アンモニウム塩、リン酸水素二アンモニウム塩及びポリリン酸アンモニウム塩等の1種又はこれらの混合物であり、常温で粉状のものである。
【0014】
また、本発明に係る非ハロゲン系難燃性組成物に用いるリン酸エステル類は、油溶性のトリアリールリン酸エステル若しくはアルキルアリールリン酸エステル等、又は、水溶性のトリアルキルリン酸エステル若しくはリン酸カルバメート等の1種又はこれらの混合物であり、常温で液状のものである。
【0015】
さらに、本発明に係る非ハロゲン系難燃性組成物に用いる樹脂水性エマルジョンは、エチレン酢酸ビニール共重合体エマルジョン(EVA)、スチレンブタジエン共重合体ラテックス(SBRラテックス)、カチオン化重合樹脂水性エマルジョン、ポリエステル樹脂水性エマルジョン、アクリルスチレン共重合体エマルジョン及びアクリル共重合体エマルジョン等の1種又はこれらの混合物である。
【0016】
本発明において、前記リン酸アンモニウム塩類水溶液と前記リン酸エステル類とを複合配合するのは、複合配合による相乗効果を得るためである。すなわち、前記リン酸アンモニウム塩類水溶液と前記リン酸エステル類との複合配合により、以下の(1)乃至(3)の作用効果が得られる。
【0017】
(1)前記リン酸アンモニウム塩類の加熱による発泡分解で火源が遮られると共に、本発明に係る非ハロゲン系難燃性組成物を表面コーティングしてなる被難燃化材であるカーテン、カーペット等の繊維類若しくは木材等、又は、本発明に係る非ハロゲン系難燃性組成物を散布してなる被難燃化材である植樹帯のバーク材等の表面が覆われ、灰化し燃え広がりがなくなる。
(2)さらに、樹脂の難燃については、最初に、本発明に係る非ハロゲン系難燃性組成物の前記樹脂水性エマルジョンのポリマー成分が燃えて小さい炎を生じるが、前記リン酸エステル類の作用により樹脂成分の燃焼の進行を抑制することができる。
(3)さらにまた、カーテン、カーペット等の繊維類若しくは木材等への表面コーティング性、又は、植樹帯等への散布性が向上すると共にコスト低減を図ることができる。
【0018】
また、本発明に係る非ハロゲン系難燃性組成物は、カーテン、カーペット等の繊維類若しくは木材等への表面コーティング、又は、植樹帯等への散布等の屋内及び屋外の使用に適するが、特に屋外での使用には前記リン酸エステル類として油溶性のものがより適している。
【0019】
さらに、本発明において、前記樹脂水性エマルジョンを用いるのは、前記リン酸エステル類を、カーテン、カーペット等の繊維類若しくは木材等への表面コーティング、又は、植樹帯等への散布における作業性を向上するために低粘度になるように配合設定し、前記リン酸エステル類を溶かし込んでμmオーダの分散難燃材とすると共に全体に均一性を保ち、難燃性を安定的に発揮させるためである。
【0020】
以下において、本発明に係る非ハロゲン系難燃性組成物における各成分の配合について説明する。
【0021】
前記リン酸アンモニウム塩類の添加量は、全成分の総重量に対して1重量%〜飽和水溶液濃度までである。前記リン酸アンモニウム塩類の添加量が全成分の総重量に対して1重量%未満の場合は、難燃効果が期待できない。また、前記リン酸アンモニウム塩類水溶液における前記リン酸アンモニウム塩類の添加量が20重量%を超えると、例えば0℃での保管中に析出する可能性がある。
【0022】
前記リン酸エステル類の添加量は、前記樹脂水性エマルジョンのポリマー成分の重量に対して4重量%〜100重量%の範囲であり、より好ましくは15重量%〜100重量%の範囲である。前記リン酸エステル類の添加量が前記樹脂水性エマルジョンのポリマー成分の重量に対して4重量%未満の場合、難燃性が低下する。また、前記リン酸エステル類の添加量が100重量%を超えると、コーティング又は散布時の作業性が低下すると共にコストが上昇し実用的でない。さらに、前記リン酸エステル類の添加量が15重量%以上であれば、特に屋外使用時における長期間に亘る難燃性保持効果が高い。
【0023】

[0008]
The inventions relating to the conventional non-halogen flame-retardant compositions described in Patent Documents 1 to 3 achieve the objects of the inventions described above. However, the present invention focuses on fabrics such as curtains, carpets, and the like. It does not disclose the composition of a non-halogen flame-retardant composition capable of imparting flame retardancy by surface coating on wood or the like or spraying on a tree planting zone or the like.
[0009]
In addition, the invention described in Patent Document 4 is an invention that imparts flame retardancy by spraying on a tree planting zone or the like, but is used outdoors, and is used for a long time against throwing away a large amount of tobacco. There is a strong need to achieve flame retardancy. Furthermore, it is not the invention of the non-halogen flame retardant composition itself.

[0012]
Here, it is preferable that the phosphoric acid ester is blended in an amount of 15% by weight or more based on the weight of the polymer component of the aqueous resin emulsion.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
The ammonium phosphates (including polymerized salts) used in the non-halogen flame retardant composition according to the present invention may be one or more of ammonium dihydrogen phosphate, diammonium hydrogen phosphate, ammonium polyphosphate and the like. And a powder at room temperature.
[0014]
Further, the phosphates used in the non-halogen flame-retardant composition according to the present invention may be an oil-soluble triaryl phosphate or an alkylaryl phosphate, or a water-soluble trialkyl phosphate or phosphorus. It is one kind of an acid carbamate or a mixture thereof, and is a liquid at room temperature.
[0015]
Further, the aqueous resin emulsion used for the non-halogen flame-retardant composition according to the present invention includes ethylene vinyl acetate copolymer emulsion (EVA), styrene butadiene copolymer latex (SBR latex), cationized polymer resin aqueous emulsion, One type such as an aqueous polyester resin emulsion, an acrylic styrene copolymer emulsion, and an acrylic copolymer emulsion, or a mixture thereof.
[0016]
In the present invention, the compounding of the aqueous solution of ammonium phosphates and the phosphoric acid ester is for obtaining a synergistic effect by the compounding. That is, the following effects (1) to (3) can be obtained by the compounding of the aqueous solution of ammonium phosphate and the phosphate.
[0017]
(1) A fire source is blocked by foaming decomposition of the ammonium phosphates by heating, and a flame-retardant material, such as a curtain or a carpet, which is obtained by coating the surface of the halogen-free flame-retardant composition according to the present invention. Fiber or wood, or the surface of a bark material of a tree planting zone, which is a flame retardant material obtained by spraying the non-halogen flame retardant composition according to the present invention, is incinerated and no longer spreads. .
(2) Further, regarding the flame retardancy of the resin, first, the polymer component of the aqueous resin emulsion of the non-halogen flame retardant composition according to the present invention burns to generate a small flame. By the action, the progress of combustion of the resin component can be suppressed.
(3) Further, the surface coating property on fibers or wood such as curtains and carpets, or the dispersibility on tree planting zones and the like can be improved, and the cost can be reduced.
[0018]
Further, the non-halogen flame-retardant composition according to the present invention is suitable for indoor and outdoor use such as curtains, surface coating on fibers or wood such as carpets, or spraying on tree planting zones, etc. In particular, oil-soluble phosphate esters are more suitable for outdoor use.
[0019]
Further, in the present invention, the use of the resin aqueous emulsion improves the workability in spraying the phosphoric acid ester on a fiber or wood such as a curtain or a carpet, or on a tree planting zone. In order to make the dispersion flame-retardant material of the order of μm by dissolving the above-mentioned phosphoric acid esters and maintain uniformity throughout, and to stably exhibit the flame retardancy. is there.
[0020]
Hereinafter, the blending of each component in the non-halogen flame retardant composition according to the present invention will be described.
[0021]
The amount of the ammonium phosphate added is from 1% by weight to the concentration of a saturated aqueous solution based on the total weight of all components. If the amount of the ammonium phosphate is less than 1% by weight based on the total weight of all components, no flame retardant effect can be expected. Further, when the amount of the ammonium phosphate salt added to the aqueous solution of the ammonium phosphate salt exceeds 20% by weight, for example, there is a possibility of precipitation during storage at 0 ° C.
[0022]
The amount of the phosphoric acid ester is in the range of 4% by weight to 100% by weight, more preferably in the range of 15% by weight to 100% by weight, based on the weight of the polymer component of the aqueous resin emulsion. When the amount of the phosphoric acid ester is less than 4% by weight based on the weight of the polymer component of the aqueous resin emulsion, the flame retardancy is reduced. On the other hand, if the amount of the phosphoric acid ester exceeds 100% by weight, the workability at the time of coating or spraying is reduced and the cost is increased, which is not practical. Further, when the amount of the phosphoric acid ester added is 15% by weight or more, the effect of maintaining the flame retardancy over a long period of time, particularly when used outdoors, is high.
[0023]

In order to evaluate the water resistance test (dissolution property, weather resistance) for evaluating the flame retardancy retention effect over a long period of time, (3) the Chukkaman (registered trademark) test after 6 months of outdoor exposure and Portable burner test (hereinafter, referred to as "outdoor exposure test"), (4) Chukkaman (registered trademark) test and portable burner test (hereinafter, referred to as "the outdoor exposure test") which are performed by immersing in water continuously for one week and then drying. In-water immersion test ”).
[0032]
Table 2 shows examples of the results of the evaluation test for flame retardancy. "O" in Table 2 indicates that in each of the flame retardancy tests, the fire extinguishes after the removal of the fire source, and has a self-extinguishing property. In addition, the surface state of the bark material after burning is blackened or incinerated, indicating that there is no downward burning.
