Description
本発明は、発泡性ポリウレタン組成物及びポリウレタン発泡体に関する。 The present invention relates to effervescent polyurethane compositions and polyurethane foams.
マンション等の集合住宅、戸建住宅、学校の各種施設、商業ビル等の建築物の断熱材として発泡ポリウレタン樹脂が用いられている。発泡ポリウレタン樹脂は難燃性が低いが、近年では火災に対する難燃性を付与した発泡ポリウレタン樹脂が用いられている。 Polyurethane foam resin is used as a heat insulating material for buildings such as condominiums, detached houses, various school facilities, and commercial buildings. Polyurethane foam resin has low flame retardancy, but in recent years, polyurethane foam resin imparted with flame retardancy against fire has been used.
例えば特許文献1は、物性が良好であり、酸素指数が高く、準不燃規格をも達成できる硬質ポリウレタンフォームの製造方法について記載しており、かかる製造方法は、有機ポリイソシアネート(A)と水(B)とを、全配合物に対して10〜70質量%の難燃剤(C)、整泡剤(D)、イソシアヌレート化反応触媒を含む触媒(E)の存在下、かつ、全イソシアネート反応性基の5モル%以下のポリオールの存在下又は不存在下で、水のイソシアネート反応性当量を9として計算したときのイソシアネートインデックス(全イソシアネート基/全イソシアネート反応性基のモル比の100倍)が150以上の条件下で、ウレア化反応及びイソシアヌレート化反応により発泡・硬化させることを特徴とする。 For example, Patent Document 1 describes a method for producing a rigid polyurethane foam having good physical properties, a high oxygen index, and achieving a semi-incombustible standard. Such a production method includes organic polyisocyanate (A) and water (A). B) is combined with the total isocyanate reaction in the presence of a catalyst (E) containing 10 to 70% by mass of a flame retardant (C), a foam stabilizer (D), and an isocyanurate-forming reaction catalyst with respect to the total formulation. Isocyanate index (100 times the molar ratio of total isocyanate groups / total isocyanate reactive groups) calculated with the isocyanate reactive equivalent of water as 9 in the presence or absence of a polyol of 5 mol% or less of the sex groups. Is characterized by foaming and curing by a urea-forming reaction and an isocyanurate-forming reaction under the condition of 150 or more.
特許文献2は、水性ウレタンプレポリマーから得られる軟質ウレタンフォーム、亜リン酸アルミニウム及び無機充填剤からなり、酸素指数が40以上であるスポンジ状成形体について記載している。 Patent Document 2 describes a sponge-like molded body composed of a soft urethane foam obtained from an aqueous urethane prepolymer, aluminum phosphite, and an inorganic filler and having an oxygen index of 40 or more.
しかしながら、上記したような発泡ポリウレタン樹脂は、十分な難燃性を有するものではなかった。 However, the foamed polyurethane resin as described above does not have sufficient flame retardancy.
本発明の目的は、難燃性が向上された発泡性ポリウレタン組成物およびポリウレタン発泡体を提供することである。 An object of the present invention is to provide a foamable polyurethane composition and a polyurethane foam having improved flame retardancy.

上記の1.〜7.の成分は混合されて発泡性ポリウレタン組成物は反応して硬化するため、その粘度は時間の経過と共に変化する。そこで発泡性ポリウレタン組成物を使用する前に、発泡性ポリウレタン組成物を二以上に分割して、発泡性ポリウレタン組成物が反応して硬化することを防止する。そして発泡性ポリウレタン組成物を使用する際に、二以上に分割しておいた発泡性ポリウレタン組成物を一つにまとめることにより、発泡性ポリウレタン組成物が得られる。 Above 1. ~ 7. The components of are mixed and the effervescent polyurethane composition reacts and cures, so its viscosity changes over time. Therefore, before using the foamable polyurethane composition, the foamable polyurethane composition is divided into two or more to prevent the foamable polyurethane composition from reacting and curing. Then, when the foamable polyurethane composition is used, the foamable polyurethane composition can be obtained by combining the foamable polyurethane compositions divided into two or more into one.
なお発泡性ポリウレタン組成物を二以上に分割するときは、二以上に分割された発泡性ポリウレタン組成物のそれぞれの成分単独は硬化が始まらず、発泡性ポリウレタン組成物のそれぞれの成分を混合した後に硬化反応が始まるようにそれぞれの成分を分割すればよい。 When the effervescent polyurethane composition is divided into two or more, each component of the effervescent polyurethane composition divided into two or more does not start to cure, and after mixing each component of the effervescent polyurethane composition. Each component may be divided so that the curing reaction starts.
発泡性ポリウレタン組成物の混合および硬化は常温で行なってもよいが、各成分を予め加熱しておいてもよい。低温では反応が十分進行せずに難燃性が発現しないため、混合および硬化の温度は0℃以上であることが好ましく、5℃以上であることがさらに好ましい。 The effervescent polyurethane composition may be mixed and cured at room temperature, but each component may be preheated. At low temperatures, the reaction does not proceed sufficiently and flame retardancy does not develop. Therefore, the mixing and curing temperatures are preferably 0 ° C. or higher, and more preferably 5 ° C. or higher.
上記の整泡剤、触媒、発泡剤および難燃剤は、ポリオールまたはイソシアネートのいずれと混合されてもよいし、ポリオールおよびイソシアネートとは別に提供されてもよいが、好ましくは整泡剤、触媒、発泡剤、および難燃剤は、ポリオールとこれらの成分とを含むポリオールプレミックスとして提供される。また、上記の7.のその他の成分もポリオールまたはイソシアネートのいずれと混合されてもよいし、ポリオールおよびイソシアネートとは別に提供されてもよいが、好ましくはポリオールプレミックスに含まれる。 The defoaming agent, catalyst, foaming agent and flame retardant described above may be mixed with either a polyol or an isocyanate, or may be provided separately from the polyol and the isocyanate, but are preferably a defoaming agent, a catalyst, a foaming agent. The agent, and the flame retardant, are provided as a polyol premix containing the polyol and these components. In addition, the above 7. Other components of may be mixed with either polyol or isocyanate, or may be provided separately from polyol and isocyanate, but are preferably included in the polyol premix.
ポリオール、イソシアネート、整泡剤、触媒、発泡剤、および難燃剤イソシアネート、好ましくはイソシアネートと、ポリオール、整泡剤、触媒、発泡剤、および難燃剤を含有するポリオールプレミックスとが混合されて生じる発泡性ポリウレタン組成物は、発泡および硬化されてポリウレタン発泡体となる。本発明は、上記の成分を含む発泡性ポリウレタン組成物から成形されたポリウレタン発泡体も包含する。 Foaming produced by mixing polyols, isocyanates, foam stabilizers, catalysts, foaming agents, and flame retardant isocyanates, preferably isocyanates, with polyol premixes containing polyols, foam stabilizers, catalysts, foaming agents, and flame retardants. The sex polyurethane composition is foamed and cured to a polyurethane foam. The present invention also includes polyurethane foams formed from foamable polyurethane compositions containing the above components.
本発明の発泡ウレタン組成物は、硬化させた発泡性ポリウレタン組成物(またはポリウレタン発泡体)の表層から5mm〜10mmの位置において、30-400℃,5℃/min昇温条件でTG-DTAを測定した場合の330℃における重量減少率が30%以下である。重量減少率は示差熱・熱重量測定計を用いて(試験開始前のサンプルの重量−330℃でのサンプルの重量)/試験開始前のサンプルの重量×100により計算される。発泡性ポリウレタン組成物(またはポリウレタン発泡体)の表層から5mm〜10mmの位置の重量減少率を測定したのは、放熱しやすい表層を避け、組成が安定している箇所を測定したためである。330℃はウレタン樹脂の熱分解温度付近の温度である。 The urethane foam composition of the present invention can be used for TG-DTA at a position of 5 mm to 10 mm from the surface layer of the cured foamable polyurethane composition (or polyurethane foam) under 30-400 ° C. and 5 ° C./min heating conditions. The weight loss rate at 330 ° C. as measured is 30% or less. The weight loss rate is calculated by using a differential thermal / thermogravimetric analyzer (weight of the sample before the start of the test-weight of the sample at −330 ° C.) / weight of the sample before the start of the test × 100. The weight loss rate at a position of 5 mm to 10 mm from the surface layer of the foamable polyurethane composition (or polyurethane foam) was measured because the surface layer where heat dissipation was easily dissipated was avoided and the composition was measured at a stable position. 330 ° C is a temperature near the thermal decomposition temperature of urethane resin.
硬化させた発泡性ポリウレタン組成物の重量減少率が30%を超えると、体積収縮が大きく、組成物の外形が大きく変形するため、難燃性能が損なわれる。理論に束縛されることを好まないが、本願発明の発泡性ポリウレタン組成物は燃焼したときに組成物の表面にチャー(固まった層)を形成することで、組成物内への酸素の侵入を遮断し、難燃性の向上に寄与しているものと考えられる。 When the weight reduction rate of the cured foamable polyurethane composition exceeds 30%, the volume shrinkage is large and the outer shape of the composition is greatly deformed, so that the flame retardant performance is impaired. Although not bound by theory, the effervescent polyurethane composition of the present invention allows oxygen to enter the composition by forming a char (solidified layer) on the surface of the composition when burned. It is considered that it shuts off and contributes to the improvement of flame retardancy.
