The method for producing a polystyrene resin extruded foam according to any one of [1] to [4 ] above,
Is a summary.
本発明は、難燃剤として、臭素化イソシアヌレート（Ａ）と、テトラブロモビスフェノールＡ−（２，３−ジブロモ−２−メチルプロピルエーテル）（Ｂ１）及びテトラブロモビスフェノールＡ−（２，３−ジブロモプロピルエーテル）（Ｂ２）からなる難燃剤（Ｂ）及び／又は臭素化スチレン−ブタジエン共重合体（Ｃ）を配合する。これらの難燃剤を組み合わせた複合難燃剤を用いることによって、該複合難燃剤を含有するポリスチレン系樹脂押出発泡体は優れた酸素指数を示すものとなる。また、得られたポリスチレン系樹脂押出発泡体を加熱溶融して再生原料としてリサイクル使用する際に、再生原料樹脂の分子量低下が抑制できる効果をも有し、良好なリサイクル性が示される。 In the present invention, brominated isocyanurate (A), tetrabromobisphenol A- (2,3-dibromo-2-methylpropyl ether) (B1) and tetrabromobisphenol A- (2,3-dibromo are used as flame retardants. Propyl ether) A flame retardant (B) composed of (B2) and / or a brominated styrene-butadiene copolymer (C) is blended. By using a composite flame retardant combined with these flame retardants, a polystyrene resin extruded foam containing the composite flame retardant exhibits an excellent oxygen index. Moreover, when the obtained polystyrene resin extruded foam is heated and melted and recycled as a recycled material, it has an effect of suppressing a decrease in the molecular weight of the recycled material resin, and exhibits good recyclability.
難燃剤（Ｂ）は、２，３−ジブロモ−２−メチルプロピル基を有する有機化合物（Ｂ１）と２，３−ジブロモプロピル基を有する有機化合物（Ｂ２）とからなる。
前記難燃剤（Ｂ１）は、テトラブロモビスフェノールＡ−（２，３−ジブロモ−２−メチルプロピルエーテル）である。
前記難燃剤（Ｂ２）は、テトラブロモビスフェノールＡ−（２，３−ジブロモプロピルエーテル）である。
前記難燃剤（Ｂ）が前記難燃剤（Ｂ１）のみからなる場合には、得られる押出発泡体の酸素指数、難燃性に優れず、特にリサイクル性が悪くなる虞がある。一方、前記難燃剤（Ｂ２）のみの場合には、リサイクル時における一定の熱安定性は確保できるが酸素指数が低下する虞がある。
さらに、難燃剤（Ａ）と（Ｂ１）を組み合わせた場合であっても、酸素指数の向上効果は見られるものの、リサイクル性を満足することはできない。また難燃剤（Ａ）と（Ｂ２）を組み合わせた場合には、リサイクル性は向上するものの、酸素指数を満足することはできない。したがって、前記難燃剤（Ｂ）は、難燃剤（Ｂ１）と（Ｂ２）からなることを要する。
前記難燃剤（Ｂ）における難燃剤（Ｂ１）と（Ｂ２）との配合割合は重量比で（Ｂ１）：（Ｂ２）＝２０：８０〜８０：２０であり、好ましくは３０：７０〜７０：３０であり、更に好ましくは３５：６５〜６５：３５である。前記の範囲内である場合には、十分な難燃性、酸素指数を示し、優れた熱安定性を有するためにリサイクル時の再生樹脂の分子量が十分な大きさの発泡体が得られる。
難燃剤（Ｂ１）と（Ｂ２）のみを使用する場合には、リサイクル性、酸素指数の全ての項目を満足する押出発泡体は得られ難く、難燃剤（Ａ）と（Ｂ）とを併用することで、リサイクル性や酸素指数に優れる押出発泡体となる。
The flame retardant (B) is composed of an organic compound (B1) having a 2,3-dibromo-2-methylpropyl group and an organic compound (B2) having a 2,3-dibromopropyl group.
The flame retardant (B1) is tetrabromobisphenol A- (2,3-dibromo-2-methylpropyl ether) .
The flame retardant (B2) is tetrabromobisphenol A- (2,3-dibromopropyl ether) .
When the flame retardant (B) is composed only of the flame retardant (B1), the obtained extruded foam is not excellent in the oxygen index and flame retardancy, and the recyclability may be deteriorated. On the other hand, when only the flame retardant (B2) is used, a certain thermal stability at the time of recycling can be secured, but the oxygen index may be lowered.
Furthermore, even when the flame retardants (A) and (B1) are combined, the oxygen index can be improved, but the recyclability cannot be satisfied. When the flame retardants (A) and (B2) are combined, the recyclability is improved, but the oxygen index cannot be satisfied. Therefore, the said flame retardant (B) needs to consist of a flame retardant (B1) and (B2).
The blending ratio of the flame retardants (B1) and (B2) in the flame retardant (B) is (B1) :( B2) = 20: 80-80: 20, preferably 30: 70-70: 30, more preferably 35:65 to 65:35. When the amount is within the above range, a foam having sufficient flame retardancy, oxygen index, and excellent thermal stability can be obtained in which the molecular weight of the recycled resin during recycling is sufficiently large.
When only the flame retardants (B1) and (B2) are used, it is difficult to obtain an extruded foam satisfying all items of recyclability and oxygen index, and the flame retardants (A) and (B) are used in combination. Thus, an extruded foam excellent in recyclability and oxygen index is obtained.
