Description

本発明は難燃性樹脂組成物に関するものであり、より詳しくは繊維製品に加工した際の各種物性や、洗浄性の改善に関する。 The present invention relates to a flame-retardant resin composition, and more specifically, to improvement of various physical properties and detergency when processed into a textile product.

従来からシートやフロアマットなどの自動車内装材にはポリエステル繊維が用いられている。自動車内装材は火災時に容易に燃焼しないことが求められているため、難燃材を添加した難燃性樹脂組成物で繊維を処理することによって難燃性を付与している。
代表的な難燃剤としてデカブロムジフェニルオキサイド(DBDPO)や三酸化アンチモン(Sb)が用いられてきたが、ハロゲン化合物は火災時にダイオキシンなどの有害物質を生成するおそれがあるため、使用が避けられるようになっている。また、アンチモンは不純物として鉛などの重金属を含むため、同様に使用が避けられるようになっている。
Conventionally, polyester fibers have been used for automobile interior materials such as seats and floor mats. Since automobile interior materials are required not to burn easily in the event of a fire, flame retardancy is imparted by treating the fibers with a flame-retardant resin composition to which a flame-retardant material is added.
Decabromdiphenyl oxide (DBDPO) and antimony trioxide (Sb 2 O 3 ) have been used as typical flame retardants, but halogen compounds may generate harmful substances such as dioxins in the event of a fire, so they can be used. It is designed to be avoided. In addition, since antimony contains heavy metals such as lead as impurities, its use can be avoided as well.

そこで、各種リン化合物が有力な選択肢として注目され、実際広く用いられている。中でも、ポリリン酸アンモニウムは難燃性に優れ、他のリン化合物よりも安全性が高く、ブリードアウトにしくいといった特長を有するため、自動車内装用繊維製品の難燃剤として用いられている。 Therefore, various phosphorus compounds have attracted attention as a promising option and are actually widely used. Among them, ammonium polyphosphate is used as a flame retardant for textile products for automobile interiors because it has excellent flame retardancy, is safer than other phosphorus compounds, and is difficult to bleed out.

一方、シートが高温多湿の条件下におかれたり、水や温水をシート上にこぼしたりした場合、ポリリン酸アンモニウムが水溶性のため表面に溶出し、「きわ付き」と呼ばれるシミやぬめりを生じることがある。また、繊維生地の染色に用いられる染料が乗員の衣服に付着する色移りや、糸がほつれ易い等の問題があった。 On the other hand, if the sheet is placed under hot and humid conditions, or if water or hot water is spilled on the sheet, ammonium polyphosphate will elute on the surface due to its water solubility, causing stains and slime called "wrinkles". Sometimes. In addition, there are problems such as color transfer in which the dye used for dyeing the fiber fabric adheres to the clothes of the occupant and the yarn is easily frayed.

本発明者らは特許文献1において、アクリル系樹脂エマルジョンおよびウレタン樹脂エマルジョンから選ばれる少なくとも一種の樹脂エマルジョン(a)、ポリエステル樹脂エマルジョン(b)、液状リン系難燃剤(c)、および芳香族基を有する界面活性剤(d)を含有することを特徴とする難燃性樹脂組成物を提案しており、きわ付きを低減しつつ優れた難燃性を付与できている。一方、樹脂エマルジョン以外の成分量を多くせざるを得ないため、タック、風合い、きわ付きのバランス取りが難しく、さらに洗浄作業の手間がかかる点に改善の余地があった。

In Patent Document 1, the present inventors have at least one resin emulsion (a), a polyester resin emulsion (b), a liquid phosphorus flame retardant (c), and an aromatic group selected from an acrylic resin emulsion and a urethane resin emulsion. We have proposed a flame-retardant resin composition containing the surfactant (d) having the above, and have been able to impart excellent flame retardancy while reducing wrinkles. On the other hand, since the amount of components other than the resin emulsion has to be increased, it is difficult to balance the tack, texture, and wrinkles, and there is room for improvement in that the cleaning work is troublesome.

ウレタン樹脂エマルジョンは、ポリエステルポリオール、ポリエーテルポリオール、ポリカーボネートポリオールなどのポリオール化合物と、多価イソシアネート化合物を有機溶媒中で反応させた後、水相に転相乳化するなどの方法により得られる。耐候性や耐水性の面からより良くはポリカーボネートポリオールを用いる事が好ましい。
The flame-retardant resin composition of the present invention contains at least one resin emulsion selected from (a) an acrylic resin emulsion and a urethane resin emulsion as a binder component.
The acrylic resin emulsion is obtained by a method such as emulsion polymerization of an acrylic monomer in the presence of an emulsifier.
The urethane resin emulsion can be obtained by reacting a polyol compound such as a polyester polyol, a polyether polyol, or a polycarbonate polyol with a polyhydric isocyanate compound in an organic solvent, and then inversion emulsifying into an aqueous phase. From the viewpoint of weather resistance and water resistance, it is preferable to use a polycarbonate polyol.

本発明の難燃性樹脂組成物は、(b)液状リン系難燃剤の乳化分散体を含有する。液状リン系難燃剤はリンを含有し、常温で液体である難燃剤である。特に制限されないが有機リン化合物が好ましく、その中でも特に芳香族系リン酸エステル単量体、芳香族系リン酸エステル縮合体であって、分子中にリンを0.1重量%以上含有するものが好ましい。前記芳香族リン酸エステル縮合体の中でも、更にフェノール、4,4´−(プロパン−2,2−ジシル)ジフェノール及びトリクロロホスフィン=オキシドの反応生成物(BDP)などが好ましい。 The flame-retardant resin composition of the present invention contains (b) an emulsified dispersion of a liquid phosphorus-based flame retardant. The liquid phosphorus flame retardant is a flame retardant that contains phosphorus and is liquid at room temperature. Although not particularly limited, organic phosphorus compounds are preferable, and among them, aromatic phosphate ester monomers and aromatic phosphate ester condensates containing 0.1% by weight or more of phosphorus in the molecule are preferable. preferable. Among the aromatic phosphate ester condensates, phenol, 4,4'-(propane-2,2-disyl) diphenol and trichlorophosphine oxide reaction product (BDP) are more preferable.

液状リン系難燃剤を乳化分散する方法は特に制限されないが、色移行や貯蔵安定性の低下が起こりにくくするため、界面活性剤を用いて乳化することが好ましく、ノニオン性界面活性剤を用いることがより好ましい。また、液状リン系難燃剤100重量部に対して、乳化に用いる界面活性剤の量は3〜15重量部程度である。 The method of emulsifying and dispersing the liquid phosphorus flame retardant is not particularly limited, but it is preferable to emulsify with a surfactant in order to prevent color transfer and deterioration of storage stability, and a nonionic surfactant should be used. Is more preferable. The amount of the surfactant used for emulsification is about 3 to 15 parts by weight with respect to 100 parts by weight of the liquid phosphorus flame retardant.

液状リン系難燃剤の配合量は、固形分を基準として前記樹脂エマルジョン(a)100重量部に対して、30〜450重量部が好ましく、より良くは50〜300重量部が好ましい。30重量部以上とすることで風合いが向上し、450重量部以下とすることでタックを抑制することが出来る。 The blending amount of the liquid phosphorus flame retardant is preferably 30 to 450 parts by weight, more preferably 50 to 300 parts by weight, based on 100 parts by weight of the resin emulsion (a) based on the solid content. When the amount is 30 parts by weight or more, the texture is improved, and when the amount is 450 parts by weight or less, tack can be suppressed.

本発明の難燃性樹脂組成物は、(c)ポリリン酸メラミンを含有する。ポリリン酸メラミンに代えて他の難燃性化合物を用いた場合、他の固形リン化合物ではきわ付きが生じるおそれがあり、他のメラミン化合物では高温多湿条件下でメラミン化合物の加水分解により経時で風合いが硬くなるおそれがある。 The flame-retardant resin composition of the present invention contains (c) melamine polyphosphate. When other flame-retardant compounds are used instead of melamine polyphosphate, other solid phosphorus compounds may cause wrinkles, and other melamine compounds have a texture over time due to hydrolysis of the melamine compounds under high temperature and high humidity conditions. May become hard.

ポリリン酸メラミンの配合量は、固形分を基準として前記樹脂エマルジョン(a)100重量部に対して、30〜450重量部が好ましく、より良くは50〜350重量部が好ましい。30重量部以上とすることで難燃性が向上し、450重量部以下とすることで風合いを損なう事を抑制することが出来る。 The blending amount of melamine polyphosphate is preferably 30 to 450 parts by weight, more preferably 50 to 350 parts by weight, based on 100 parts by weight of the resin emulsion (a) based on the solid content. When the amount is 30 parts by weight or more, the flame retardancy is improved, and when the amount is 450 parts by weight or less, it is possible to suppress the deterioration of the texture.

本発明の難燃性樹脂組成物のpHは7.0以上である必要があり、より良くは7.2以上である。7.0未満の場合は洗浄性が低下するが、これは液状リン系難燃剤の乳化分散が不安定化するためと考えられる。ポリリン酸メラミンを添加することによって組成物のpHは低下するため、アンモニア水等を添加することにより、pHを高めるように調整する必要がある。 The pH of the flame-retardant resin composition of the present invention needs to be 7.0 or higher, and better is 7.2 or higher. If it is less than 7.0, the detergency is lowered, which is considered to be due to the destabilization of the emulsified dispersion of the liquid phosphorus flame retardant. Since the pH of the composition is lowered by adding melamine polyphosphate, it is necessary to adjust the pH by adding aqueous ammonia or the like.

本発明の難燃性樹脂組成物には前記配合成分の他、本発明の優れた効果を妨げない範囲において、さらに各種添加剤を配合できる。例えば、水酸化アルミニウム、ホウ素系化合物、メラミン系化合物、ジルコニウム系化合物などの難燃剤、イソシアネート化合物などの架橋剤、増粘剤などが挙げられる。
また、無機充填剤、分散剤、増粘剤、湿潤剤、発泡剤、整泡剤、消泡剤、顔料、染料、可塑剤、老化防止剤、紫外線吸収剤、防腐剤などが使用できる。

Examples thereof include flame retardants such as aluminum hydroxide, boron compounds, melamine compounds and zirconium compounds, cross-linking agents such as isocyanate compounds, and thickeners.
Further, inorganic fillers, dispersants, thickeners, wetting agents, foaming agents, foam stabilizers, antifoaming agents, pigments, dyes, plasticizers, antiaging agents, ultraviolet absorbers, preservatives and the like can be used.

以上のようにして得られた本発明の難燃性樹脂組成物の固形分及び粘度は、いずれも特に限定されるものではないが、該組成物の沈降安定性等の観点より、一般に固形分は30〜70重量%、好ましくは30〜60重量%、粘度(BH型粘度計、20℃、10rpm)は10,000〜60,000mPa・s、好ましくは10,000〜40,000mPa・sである。 The solid content and viscosity of the flame-retardant resin composition of the present invention obtained as described above are not particularly limited, but are generally solid contents from the viewpoint of sedimentation stability and the like of the composition.

The car seat fabric is not particularly limited as long as it does not generate harmful gas in the event of a fire and uses a treatment agent that does not generate formaldehyde as a treatment agent such as a shrink-proof processing agent. For example, synthetic fibers such as polyester, polypropylene, nylon and acrylic, natural fibers such as wool or blends thereof can be mentioned.

本発明の難燃性樹脂組成物のバッキング層としての塗布量は、固形分で10〜200g/m、好ましくは20〜150g/mである。塗布量が10g/m未満では難燃性が不十分となるおそれがあり、200g/mを超える場合は風合いを損ない、経済的にも好ましくない。 The coating amount of the flame-retardant resin composition of the present invention as a backing layer is 10 to 200 g / m 2 in terms of solid content, preferably 20 to 150 g / m 2 . If the coating amount is less than 10 g / m 2 , the flame retardancy may be insufficient, and if it exceeds 200 g / m 2 , the texture is impaired, which is economically unfavorable.
