本発明は難燃性、断熱性、電解液耐性、付形性に優れた二次電池容器用発泡体に関する。 The present invention relates to a foam for a secondary battery container excellent in flame retardancy, heat insulation, electrolyte resistance, and shapeability.
近年、環境保護の観点から、ハイブリッド自動車や電気自動車が注目を浴びている。これらの性能に大きく影響するのが、リチウムイオン電池等の二次電池の発電効率であり、特に電気自動車が社会に広く普及するには、さらなる効率向上や、電池寿命延長等の性能改善が必要である。 In recent years, hybrid vehicles and electric vehicles have attracted attention from the viewpoint of environmental protection. The power generation efficiency of secondary batteries such as lithium-ion batteries greatly affects these performances. In particular, in order for electric vehicles to spread widely in society, further efficiency improvements and performance improvements such as battery life extension are required. It is.
二次電池は、充放電の際に発熱する事が知られている。この発熱により二次電池本体の温度が過度に上昇すると、性能が低下する事に加え、電池内部の反応が暴走する危険性が高くなったり、電池寿命が短命化してしまう為、電池を冷却する必要がある。一方、電池温度が低くなりすぎると、発電効率や放電効率が低下してしまうので、最適温度に冷却し、維持する事が重要である。通常、電気自動車等に使用される二次電池は、複数の電池が直列に接続されている。この際、電池間の温度、すなわち、効率にばらつきがあると、二次電池全体としての効率が悪化する原因となるので、電池の温度をいかに均一にするかも重要な技術課題となっている。 It is known that secondary batteries generate heat during charging and discharging. If the temperature of the secondary battery body rises excessively due to this heat generation, in addition to performance degradation, there is a high risk of runaway reaction inside the battery, and the battery life will be shortened. There is a need. On the other hand, if the battery temperature becomes too low, the power generation efficiency and the discharge efficiency are lowered. Therefore, it is important to cool and maintain the battery at the optimum temperature. Usually, a secondary battery used in an electric vehicle or the like has a plurality of batteries connected in series. At this time, if there is a variation in the temperature between the batteries, that is, the efficiency, the efficiency of the secondary battery as a whole deteriorates. Therefore, how to make the temperature of the battery uniform is also an important technical problem.
特許文献１、２では、電池を効率よく冷却する為に、冷風の流路を工夫し設計している。一方、特許文献３では、二次電池容器の一部に発泡体を使用し、耐振動性、耐衝撃性を向上させている。 In patent documents 1 and 2, in order to cool a battery efficiently, the channel of cold air is devised and designed. On the other hand, in patent document 3, a foam is used for a part of secondary battery container, and vibration resistance and impact resistance are improved.
しかしながら、特許文献１や２に記載の方法では、二次電池周囲の熱源への配慮がなされておらず、周囲温度という外因由来の温度斑を制御する事は不可能であった。特許文献３には発泡体が使用されているが、安全性への配慮がなされておらず、電池の電解液漏れによる発火等のトラブル対応が不十分であった。また、板状発泡体、フィルム、アルミ箔を積層している事から柔軟性が不足しており、部品をはめ込み固定するビスレスフレームには不適であった。また付形性も乏しく、複雑な形状に加工する事が困難であった。 However, in the methods described in Patent Documents 1 and 2, consideration is not given to the heat source around the secondary battery, and it has been impossible to control the temperature spots derived from external factors such as the ambient temperature. Patent Document 3 uses a foam, but safety is not taken into consideration, and troubles such as ignition due to battery electrolyte leakage are insufficient. In addition, since a plate-like foam, a film, and an aluminum foil are laminated, the flexibility is insufficient, and it is not suitable for a screwless frame for fitting and fixing parts. Further, the shapeability is poor and it is difficult to process into a complicated shape.
本発明は、電解液が漏れて付着しても変形する事がなく、さらに電解液が発火した場合でも延焼を防止する安全性を有しつつ、二次電池の周囲を断熱する事が可能な二次電池用発泡体を提供することを目的とする。 The present invention does not deform even if the electrolytic solution leaks and adheres, and even if the electrolytic solution ignites, it has the safety to prevent the spread of fire and can insulate the periphery of the secondary battery. It aims at providing the foam for secondary batteries.
本発明者らは、前記課題を解決するため、特定の樹脂からなり、高い難燃性を有する発泡体が、二次電池の収納容器に適していることを見出し、本発明をなすに至った。 In order to solve the above problems, the present inventors have found that a foam made of a specific resin and having high flame retardancy is suitable for a storage container for a secondary battery, and has led to the present invention. .

本発明の発泡体は、ポリフェニレンエーテル系樹脂、ポリスチレン系樹脂、難燃剤、及びゴム成分を含む基材樹脂からなることが最も好ましい。この場合の各成分の含有量は、ポリフェニレンエーテル系樹脂４０〜９４質量％、難燃剤５〜３０質量％、及びゴム成分０．３〜１０質量％であり、残部がポリスチレン系樹脂からなることが好ましい。 Most preferably, the foam of the present invention comprises a base resin including a polyphenylene ether resin, a polystyrene resin, a flame retardant, and a rubber component. In this case, the content of each component is 40 to 94% by mass of a polyphenylene ether resin, 5 to 30% by mass of a flame retardant, and 0.3 to 10% by mass of a rubber component, and the balance is made of a polystyrene resin. preferable.
ポリフェニレンエーテル系樹脂の含有量が４０質量％以上であれば、耐熱性に優れ、さらに難燃性、特に燃焼時の樹脂だれ防止性能が著しく向上する。燃焼時の樹脂だれを防ぐには、（１）燃焼時間を短くし、（２）樹脂の耐熱性を上げる（軟化しにくくする）ことが重要となるが、難燃剤の添加量を増やすだけでは（２）には逆効果であり、より薄肉のサンプルでの樹脂だれを防止するには、ポリフェニレンエーテル系樹脂の含有量を４０質量％以上にすることが好ましい。一方、ポリフェニレンエーテル系樹脂の含有量が９４質量％以下であれば、基材樹脂の熱劣化が起こりにくくなり、発泡、成形等の加工がしやすくなる。 When the content of the polyphenylene ether-based resin is 40% by mass or more, the heat resistance is excellent, and further, the flame retardancy, particularly the resin dripping prevention performance during combustion is remarkably improved. In order to prevent dripping of the resin during combustion, it is important to (1) shorten the combustion time and (2) increase the heat resistance of the resin (make it difficult to soften), but just increasing the amount of flame retardant added (2) has an adverse effect, and in order to prevent resin dripping in a thinner sample, the content of the polyphenylene ether-based resin is preferably 40% by mass or more. On the other hand, when the content of the polyphenylene ether-based resin is 94% by mass or less, the base resin is less likely to be thermally deteriorated, and processing such as foaming and molding becomes easy.
基材樹脂中のポリフェニレンエーテル系樹脂の含有量は、より好ましくは４５〜９０質量％、さらにより好ましくは５０〜８５質量％である。含有量を４５〜９０質量％とすることにより、耐熱性を維持しつつ、発泡温度、成形温度がより低くなり、より加工しやすくなる。 The content of the polyphenylene ether resin in the base resin is more preferably 45 to 90% by mass, and still more preferably 50 to 85% by mass. By setting the content to 45 to 90% by mass, the foaming temperature and the molding temperature become lower while maintaining heat resistance, and the processing becomes easier.
基材樹脂中の難燃剤の含有量は５〜３０質量％が好ましい。難燃剤の含有量が５質量％以上であると、所望の難燃性が発現しやすくなる。逆に、３０質量％以下だと、難燃剤による基材樹脂の可塑化効果が適度となり、耐熱性が向上する。さらに、発泡時の樹脂の伸張粘度が向上し、発泡倍率が上げられるようになり、発泡体の独立気泡率が向上し、成形体への成形加工性に優れるようになる。このように、難燃性と発泡性のバランスを調整することは非常に重要である。 The content of the flame retardant in the base resin is preferably 5 to 30% by mass. When the content of the flame retardant is 5% by mass or more, desired flame retardancy is easily exhibited. On the other hand, when it is 30% by mass or less, the plasticizing effect of the base resin by the flame retardant becomes appropriate, and the heat resistance is improved. Furthermore, the expansion viscosity of the resin at the time of foaming is improved, the foaming ratio can be increased, the closed cell ratio of the foam is improved, and the molding processability to the molded body is improved. Thus, it is very important to adjust the balance between flame retardancy and foamability.
基材樹脂中のゴム成分の含有量は０．３〜１０質量％が好ましく、０．５〜８質量％がより好ましく、１〜５質量％がさらに好ましい。０．３質量％以上であると所望の難燃性が発現しやすくなる。さらに、０．５質量％以上であると樹脂の柔軟性、伸びに優れ、発泡時に発泡セル膜が破膜しにくく、発泡倍率が上がり、成形加工性や機械強度に優れる発泡体となる。難燃性を重視すると、ポリフェニレンエーテル系樹脂や難燃剤は、より多く添加する方が好ましいが、これらはどちらも添加量が増えると発泡性には悪影響を与える。そのような組成において、発泡性を付与させるのにゴム成分は好適である。これは特に、常温から徐々に温度を上げ、非溶融状態で樹脂を発泡させるビーズ発泡において重要である。一方、ゴム成分の含有量は１０質量％以下であれば所望の難燃性が発現しやすくなる。さらに、８質量％以下であると、十分な耐熱性が得られる。ゴム粒子の形状は特には限定されず、ゴム成分を外殻とする粒子の内部に複数のポリスチレン系樹脂微粒子を内包した、いわゆるサラミ構造を形成していてもよく、ゴム成分を外殻とする粒子の内部に単数のスチレン系樹脂微粒子を内包した、いわゆるコアシェル構造であってもよい。ゴム成分のゴム粒径は特には限定されないが、サラミ構造の場合は０．５〜５．０μｍ、コアシェル構造の場合は０．１〜１．０μｍが好ましい。この範囲であると、より優れた発泡性を発揮しやすい。 The content of the rubber component in the base resin is preferably 0.3 to 10% by mass, more preferably 0.5 to 8% by mass, and further preferably 1 to 5% by mass. When the content is 0.3% by mass or more, desired flame retardancy is easily exhibited. Furthermore, if it is 0.5% by mass or more, the resin is excellent in flexibility and elongation, the foamed cell film is difficult to break at the time of foaming, the foaming ratio is increased, and a foam having excellent molding processability and mechanical strength is obtained. If the flame retardancy is regarded as important, it is preferable to add more polyphenylene ether-based resin and flame retardant, but both of these adversely affect the foaming properties as the addition amount increases. In such a composition, a rubber component is suitable for imparting foamability. This is particularly important in foaming beads in which the temperature is gradually raised from room temperature and the resin is foamed in a non-molten state. On the other hand, if the content of the rubber component is 10% by mass or less, desired flame retardancy is easily exhibited. Furthermore, sufficient heat resistance is acquired as it is 8 mass% or less. The shape of the rubber particles is not particularly limited, and a so-called salami structure in which a plurality of polystyrene resin fine particles are encapsulated inside a particle having a rubber component as an outer shell may be formed, and the rubber component is an outer shell. A so-called core-shell structure in which a single styrene resin fine particle is encapsulated inside the particle may be used. The rubber particle size of the rubber component is not particularly limited, but is preferably 0.5 to 5.0 μm for the salami structure and 0.1 to 1.0 μm for the core-shell structure. Within this range, more excellent foaming properties are likely to be exhibited.
次に、本発明におけるポリカーボネート系樹脂は、ビスフェノール類とホスゲン（若しくはジフェニルカーボネート）とから誘導される炭酸エステル樹脂とすることが好ましく、高いガラス転移点と耐熱性とを有することが特徴である。このようなポリカーボネート系樹脂としては、例えば、２，２’−ビス（４−ヒドロキシフェニル）プロパン（ビスフェノールＡ）、２，２’−ビス（４−ヒドロキシフェニル）ブタン（ビスフェノールＢ）、１，１’−ビス（４−ヒドロキシフェニル）エタン、ビス（４−ヒドロキシフェニル）メタン（ビスフェノールＦ）、１，１−ビス（４ーヒドロキシフェニル）シクロヘキサン、１，１−ビス（４ーヒドロキシフェニル）シクロペンタン、１，１−ビス（４ーヒドロキシフェニル）−１−フェニルメタン、１，１−ビス（４ーヒドロキシフェニル）−１−フェニルエタン、１，２−ビス（４ーヒドロキシフェニル）エタン等から誘導されたポリカーボネートが好適である。これらのポリカーボネートは、一般に１４０〜１５５℃のガラス転移点（Ｔｇ）を有する。 Next, the polycarbonate resin in the present invention is preferably a carbonate ester resin derived from bisphenols and phosgene (or diphenyl carbonate), and has a high glass transition point and heat resistance. Examples of such polycarbonate resins include 2,2′-bis (4-hydroxyphenyl) propane (bisphenol A), 2,2′-bis (4-hydroxyphenyl) butane (bisphenol B), 1,1.

本発明の発泡体は、ＵＬ規格のＵＬ−９４垂直法（２０ｍｍ垂直燃焼試験）に準拠して測定される難燃性がＶ−０又はＶ−１である必要があり、好ましくはＶ−０である。これは、二次電池に使用されている電解液は引火性であり、熱により反応が暴走した際や、充放電工程等で容器から漏れた際に発火する危険があるからである。発泡体の難燃性がＶ−０又はＶ−１であると、発火時の延焼が抑えられ、安全性が向上する。 The foam of the present invention needs to have a flame retardancy measured according to UL standard UL-94 vertical method (20 mm vertical combustion test) of V-0 or V-1, preferably V-0. It is. This is because the electrolyte used in the secondary battery is flammable and may ignite when the reaction runs away due to heat or leaks from the container in a charge / discharge process or the like. When the flame retardancy of the foam is V-0 or V-1, the spread of fire at the time of ignition is suppressed, and the safety is improved.
本発明の発泡体の発泡倍率は特には限定されないが、１．５〜４０ｃｃ／ｇが好ましく、２〜２５ｃｃ／ｇがより好ましい。この範囲であると、軽量化のメリットを活かしつつ、優れた難燃性を維持しやすくなる傾向にある。さらに好ましくは３〜２０ｃｃ/ｇである。３ｃｃ/ｇ以上になると、電池効率向上効果に大きな影響を与える断熱性やビスレス固定に必要な柔軟性がより効果的に発現しやすくなる。ビスレス固定は、部品をはめ込む際に基材を押し広げ、部品を挿入した後、基材が元に戻ろうとする力で部品を固定するので、柔軟さと変形に対する回復力が重要となる。これを両立しうるのが発泡体の大きな特徴であり、未発泡の樹脂や金属では、なしえない効果である。一方、２０ｃｃ/ｇ以下になると剛性や長期クリープ性に優れる。これは、瞬間的な応力による変形が小さいだけでなく、長時間応力に晒され続けた場合でも径時で寸法変化しにくい事を意味し、発泡体を緩衝材としてではなく部品として使用するには重要な項目である。また、電解液耐性もより発揮しやすい。 The expansion ratio of the foam of the present invention is not particularly limited, but is preferably 1.5 to 40 cc / g, and more preferably 2 to 25 cc / g. Within this range, it tends to be easy to maintain excellent flame retardancy while taking advantage of the advantages of weight reduction. More preferably, it is 3-20 cc / g. When it is 3 cc / g or more, the heat insulation that greatly affects the battery efficiency improvement effect and the flexibility required for screwless fixation are more easily expressed. In screwless fixing, the base material is expanded when the part is fitted, and after the part is inserted, the part is fixed with a force that the base material tries to return to the original state. Therefore, flexibility and recovery force against deformation are important. It is a great feature of the foam that can achieve both of these, and an effect that cannot be achieved with unfoamed resin or metal. On the other hand, when it is 20 cc / g or less, the rigidity and long-term creep properties are excellent. This means that not only the deformation due to instantaneous stress is small, but also that it is difficult to change the dimensions with time even if it is exposed to stress for a long time, so that the foam can be used as a part rather than as a cushioning material. Is an important item. Moreover, electrolyte solution resistance is also more easily exhibited.
本発明の発泡体の熱伝導率は特には限定されないが、０．１０Ｗ/（ｍ・Ｋ）以下が好ましく、０．０５Ｗ/（ｍ・Ｋ）以下がより好ましい。熱伝導率が０．１０Ｗ/（ｍ・Ｋ）であると、より薄い厚みで断熱性能を発揮でき、省スペース化しやすくなる。さらに、電解液が漏洩した場合でも、周囲を断熱する事により発火しにくくする効果も出やすい。前述したように、二次電池の効率は温度に大きく影響される。二次電池の周囲を断熱する事により、電池近傍にある熱源の影響を排除できる効果の他、さらに重要なのは、寒冷地等の低温環境下での効率改善効果である。二次電池は、充放電中は発熱するが、未使用時はもちろん発熱しない。よって、使用しない状態で寒冷地に放置されると、電池周囲は過度に冷却される。その結果、実際に二次電池を使用し始める時には、非常に効率の低い低温環境下で稼動する事になる。その際、ヒーター等で加熱する対策が考えられるが、二次電池周囲を断熱していると、外気温の影響による温度低下を防止できる事に加え、ヒーターで加熱する際の周囲への放熱も防げ、より効率よく二次電池を加熱する事が可能になる。これは、自動車や太陽電池等、地球上の種々の環境で使用される物への応用には重要な性能である。断熱による効率向上は、二次電池以外にも、リチウムイオンキャパシタ等の他の蓄電媒体にも同様の効果があり、有用である。 The thermal conductivity of the foam of the present invention is not particularly limited, but is preferably 0.10 W / (m · K) or less, and more preferably 0.05 W / (m · K) or less. When the thermal conductivity is 0.10 W / (m · K), the heat insulation performance can be exhibited with a thinner thickness, and space saving is facilitated. Furthermore, even when the electrolyte leaks, the effect of making it difficult to ignite easily is obtained by insulating the surroundings. As described above, the efficiency of the secondary battery is greatly influenced by the temperature. In addition to the effect of eliminating the influence of the heat source in the vicinity of the battery by insulating the periphery of the secondary battery, more important is the effect of improving the efficiency in a low-temperature environment such as a cold region. Secondary batteries generate heat during charging and discharging, but of course do not generate heat when not in use. Therefore, if the battery is left in a cold area when not in use, the battery periphery is excessively cooled. As a result, when actually starting to use the secondary battery, it operates in a low temperature environment with very low efficiency. At that time, measures to heat with a heater etc. can be considered, but if the surroundings of the secondary battery are insulated, in addition to preventing temperature drop due to the influence of outside air temperature, heat dissipation to the surroundings when heating with a heater is also possible The secondary battery can be heated more efficiently. This is an important performance for application to objects used in various environments on the earth such as automobiles and solar cells. The efficiency improvement by heat insulation has the same effect on other power storage media such as a lithium ion capacitor in addition to the secondary battery, and is useful.
本発明の発泡体の１００℃での加熱寸法変化率は特に限定されないが、１０％以下が好ましく、５％以下がより好ましく、３％以下がさらに好ましい。加熱寸法変化率が１０％以下であると、耐熱性に優れるため、高温の環境下で使用する部材にも適用が可能であり、さらには夏場の高温環境下に長期間保存しておくことも可能である。 Although the heating dimensional change rate at 100 ° C. of the foam of the present invention is not particularly limited, it is preferably 10% or less, more preferably 5% or less, and further preferably 3% or less. When the heating dimensional change rate is 10% or less, the heat resistance is excellent, so it can be applied to a member used in a high temperature environment, and can be stored for a long time in a high temperature environment in summer. Is possible.
本発明の発泡体の荷重たわみ温度（ＨＤＴ）は特に限定されないが、６０℃以上が好ましく、７０℃以上がより好ましい。荷重たわみ温度が６０℃以上であると、耐熱性に優れ、上記と同様の効果が得られる。 The deflection temperature under load (HDT) of the foam of the present invention is not particularly limited, but is preferably 60 ° C. or higher, more preferably 70 ° C. or higher. When the deflection temperature under load is 60 ° C. or higher, the heat resistance is excellent and the same effect as described above can be obtained.
本発明の発泡体に残存する脂肪族炭化水素系ガスの残留濃度は、１０００体積ｐｐｍ以下が好ましい。なお、本明細書において、脂肪族炭化水素系ガスの残留濃度とは、発泡体中に含まれる脂肪族炭化水素系ガスの体積を発泡体の体積で除して求めた値（体積ｐｐｍ）であり、１体積ｐｐｍ（以下、単に「ｐｐｍ」ともいう。）は０．０００１体積％に相当する。脂肪族炭化水素系ガスとしては、プロパン、ｎ−ブタン、ｉ―ブタン、ｎ−ペンタン、ｉ−ペンタン、ネオペンタン等が挙げられる。脂肪族炭化水素系ガスの残留濃度が１０００ｐｐｍ以下であると、燃焼時に種火が長時間くすぶったり（グローイングという）しにくくなる。ＵＬ−９４等の燃焼試験においては、燃焼時間に加えグローイング時間が規定されており、上記残存ガス量が少ないと、燃焼試験、特にＶ−０という規格をクリアしやすくなる。発泡体に残存する脂肪族炭化水素系ガスの残留濃度を１０００ｐｐｍ以下とするには、例えば、発泡剤として無機ガスを用いることや、発泡ビーズを高温（例えば、４０℃〜８０℃の間で任意に設定することができる）条件下に長時間置き残存するガスを放出させる「熟成工程」を経ることにより行うことができる。 The residual concentration of the aliphatic hydrocarbon gas remaining in the foam of the present invention is preferably 1000 ppm by volume or less. In the present specification, the residual concentration of the aliphatic hydrocarbon gas is a value (volume ppm) obtained by dividing the volume of the aliphatic hydrocarbon gas contained in the foam by the volume of the foam. Yes, 1 volume ppm (hereinafter also simply referred to as “ppm”) corresponds to 0.0001 volume%. Examples of the aliphatic hydrocarbon gas include propane, n-butane, i-butane, n-pentane, i-pentane, neopentane and the like. When the residual concentration of the aliphatic hydrocarbon gas is 1000 ppm or less, it is difficult for the seed fire to smolder for a long time (called glowing) during combustion. In the combustion test such as UL-94, the glowing time is specified in addition to the combustion time. If the amount of the residual gas is small, it becomes easy to clear the combustion test, particularly the standard of V-0. In order to set the residual concentration of the aliphatic hydrocarbon gas remaining in the foam to 1000 ppm or less, for example, an inorganic gas is used as a foaming agent, or the foam beads are heated at a high temperature (for example, between 40 ° C. and 80 ° C. It can be performed by passing through a “ripening step” in which the gas remaining for a long time is released under the conditions.
次に、本発明の発泡体の製造方法について説明する。
本発明の発泡体の発泡方法は特には限定されないが、例として押出発泡法、ビーズ発泡法、射出発泡法等が挙げられる。この中でもビーズ発泡が好ましい。押出発泡の場合、発泡体は板状であり、これを加工するには所望の形状に切断する抜き工程や、切り取ったパーツを貼り合わせる熱貼り工程が必要になるが、ビーズ発泡の場合、所望の形状の型を作成し、そこに発泡ビーズを充填させて成形するので、より微細な形状や複雑な形状に成形しやすいからである。例えば、１つの発泡成形体の中にリブやフック形状を複雑に組み合わせる事ができ、これにより、二次電池の断熱材としてのみではなく、二次電池やその他部品をビスレスで固定する保持材としての役割を担う事ができる。ビスレスする事により工程の簡略化や部品点数削減効果があり、これはコストメリットだけでなく、軽量化にも大きく貢献するので有用である。射出発泡法でも複雑形状の加工は可能だが、ビーズ発泡の方が発泡倍率を上げやすく、断熱性の他、ビスレス固定に必要な柔軟性を発現しやすいので好ましい。
Next, the manufacturing method of the foam of this invention is demonstrated.
The foaming method of the foam of the present invention is not particularly limited, and examples thereof include an extrusion foaming method, a bead foaming method, and an injection foaming method. Among these, bead foaming is preferable. In the case of extrusion foaming, the foam is plate-shaped, and in order to process this, a punching process for cutting into a desired shape and a heat bonding process for bonding the cut parts are required. This is because a mold having the shape is prepared and filled with foam beads to be molded, so that it can be easily molded into a finer or complicated shape. For example, ribs and hook shapes can be combined in one foam molded body in a complex manner, so that not only as a heat insulating material for secondary batteries, but also as a holding material for fixing secondary batteries and other parts with screws. Can play the role of By screwless, there is an effect of simplifying the process and reducing the number of parts, which is useful because it contributes not only to cost merit but also to weight reduction. Although it is possible to process complex shapes even by the injection foaming method, bead foaming is preferable because it is easy to increase the expansion ratio, and in addition to heat insulation, it is easy to express flexibility necessary for screwless fixing.
発泡剤は特には限定されず、一般的に用いられているガスを使用することができる。その例として、空気、炭酸ガス、窒素ガス、酸素ガス、アンモニアガス、水素ガス、アルゴンガス、ヘリウムガス、ネオンガス等の無機ガス、トリクロロフルオロメタン（Ｒ１１）、ジクロロジフルオロメタン（Ｒ１２）、クロロジフルオロメタン（Ｒ２２）、テトラクロロジフルオロエタン（Ｒ１１２）ジクロロフルオロエタン（Ｒ１４１ｂ）クロロジフルオロエタン（Ｒ１４２ｂ）、ジフルオロエタン（Ｒ１５２ａ）、ＨＦＣ−２４５ｆａ、ＨＦＣ−２３６ｅａ、ＨＦＣ−２４５ｃａ、ＨＦＣ−２２５ｃａ等のフルオロカーボンや、プロパン、ｎ−ブタン、ｉ−ブタン、ｎ−ペンタン、ｉ−ペンタン、ネオペンタン等の飽和炭化水素、ジメチルエーテル、ジエチルエーテル、メチルエチルエーテル、イソプロピルエーテル、ｎ−ブチルエーテル、ジイソプロピルエーテル、フラン、フルフラール、２−メチルフラン、テトラヒドロフラン、テトラヒドロピラン等のエーテル類、ジメチルケトン、メチルエチルケトン、ジエチルケトン、メチルｎ−プロピルケトン、メチルｎ―ブチルケトン、メチルｉ−ブチルケトン、メチルｎ−アミルケトン、メチルｎ−ヘキシルケトン、エチルｎ−プロピルケトン、エチルｎ−ブチルケトン等のケトン類、メタノール、エタノール、プロピルアルコール、ｉ−プロピルアルコール、ブチルアルコール、ｉ−ブチルアルコール、ｔ−ブチルアルコール等のアルコール類、蟻酸メチルエステル、蟻酸エチルエステル、蟻酸プロピルエステル、蟻酸ブチルエステル、蟻酸アミルエステル、プロピオン酸メチルエステル、プロピオン酸エチルエステル等のカルボン酸エステル類、塩化メチル、塩化エチル等の塩素化炭化水素類等が挙げられる。難燃性の観点から、発泡剤は可燃性や支燃性がないことが好ましく、ガスの安全性の観点から無機ガスがより好ましい。また、無機ガスは炭化水素等の有機ガスに比べ樹脂に溶けにくく、発泡工程や成形工程の後、樹脂からガスが抜けやすいので、成形品の経時での寸法安定性がより優れる利点もある。さらに、残存ガスによる樹脂の可塑化も起こりにくく、熟成等の工程を経ずに、より早い段階から優れた耐熱性を発現しやすいメリットもある。無機ガスの中でも、樹脂への溶解性、取り扱いの容易さの観点から、炭酸ガスが好ましい。 A foaming agent is not specifically limited, The gas generally used can be used. Examples thereof include air, carbon dioxide gas, nitrogen gas, oxygen gas, ammonia gas, hydrogen gas, argon gas, helium gas, neon gas and other inorganic gases, trichlorofluoromethane (R11), dichlorodifluoromethane (R12), chlorodifluoromethane. (R22), tetrachlorodifluoroethane (R112) dichlorofluoroethane (R141b) chlorodifluoroethane (R142b), difluoroethane (R152a), fluorocarbons such as HFC-245fa, HFC-236ea, HFC-245ca, HFC-225ca, propane, n -Saturated hydrocarbons such as butane, i-butane, n-pentane, i-pentane, neopentane, dimethyl ether, diethyl ether, methyl ethyl ether, isopropyl ether, n-butyl ether Ethers such as tellurium, diisopropyl ether, furan, furfural, 2-methylfuran, tetrahydrofuran, tetrahydropyran, dimethyl ketone, methyl ethyl ketone, diethyl ketone, methyl n-propyl ketone, methyl n-butyl ketone, methyl i-butyl ketone, methyl n- Ketones such as amyl ketone, methyl n-hexyl ketone, ethyl n-propyl ketone, ethyl n-butyl ketone, alcohols such as methanol, ethanol, propyl alcohol, i-propyl alcohol, butyl alcohol, i-butyl alcohol, and t-butyl alcohol Formic acid methyl ester, formic acid ethyl ester, formic acid propyl ester, formic acid butyl ester, formic acid amyl ester, propionic acid methyl ester, propionic acid ethyl ester Carboxylic acid esters, methyl chloride, chlorinated hydrocarbons such as ethyl chloride, and the like. From the viewpoint of flame retardancy, the foaming agent preferably has no flammability or flame support, and inorganic gas is more preferable from the viewpoint of gas safety. In addition, the inorganic gas is less soluble in the resin than the organic gas such as hydrocarbon, and the gas is likely to escape from the resin after the foaming process or the molding process, so that there is an advantage that the dimensional stability of the molded product over time is further improved. Further, the resin is hardly plasticized by the residual gas, and there is an advantage that excellent heat resistance is easily exhibited from an earlier stage without passing through a process such as aging. Among inorganic gases, carbon dioxide gas is preferred from the viewpoints of solubility in resins and ease of handling.
発泡体を目的の形状に加工する方法は特には限定されないが、例として発泡ビーズや溶融樹脂を金型に充填し成形する方法や、鋸刃や型ぬき刃等の刃物により切断する方法や、ミルにより切削する方法が挙げられる。また、複数の発泡体を熱や接着剤により接着させる事も可能である。
本発明の発泡体は、単独で使用してもよいし、金属や未発泡樹脂等と組み合わせてもよい。その際、各々成形加工した物を接着してもよいし、一体成形を行ってもよい。

It is also possible to bond a plurality of foams by heat or an adhesive.
The foam of the present invention may be used alone or in combination with a metal or an unfoamed resin. At that time, each molded product may be bonded, or may be integrally molded.

ポリフェニレンエーテル系樹脂（ＰＰＥ）としてＳ２０１Ａ（旭化成ケミカルズ（株）製）を５０質量％、非ハロゲン系難燃剤としてビスフェノールＡ−ビス（ジフェニルホスフェート）（ＢＢＰ）を１５質量％、ゴム成分が０．６質量％となるようにゴム濃度が６質量％の耐衝撃性ポリスチレン樹脂（ＨＩＰＳ）１０質量％と汎用ポリスチレン樹脂（ＰＳ）としてＧＰ６８５（ＰＳジャパン（株）製）２５質量％を加え、押出機にて加熱溶融混練の後に押出し、基材樹脂ペレットを作製した。特開平４−３７２６３０の実施例１に記載の方法に準じ、基材樹脂ペレットを耐圧容器に収容し、容器内の気体を乾燥空気で置換した後、発泡剤として二酸化炭素（気体）を注入し、圧力３．２ＭＰａ、温度１１℃の条件下で３時間かけて基材樹脂ペレットに対して二酸化炭素を７重量％含浸させ、基材樹脂ペレットを発泡炉内で攪拌羽を７７ｒｐｍにて回転させながら加圧水蒸気により発泡させた。この発泡ビーズを０．５ＭＰａまで１時間かけて昇圧し、その後０．５ＭＰａで８時間保持し、加圧処理を施した。これを、水蒸気孔を有する型内成形金型内に充填し、加圧水蒸気で加熱して発泡ビーズ相互を膨張・融着させた後、冷却し、成形金型より取り出した。この発泡体の難燃性はＶ―０であった。これを用い、二次電池用発泡体としての性能評価を実施した所、電解液耐性、断熱性、部品固定性能、安全性に優れる結果となった（表１）。
[Example 1]
S201A (Asahi Kasei Chemicals Corporation) as a polyphenylene ether resin (PPE) is 50% by mass, bisphenol A-bis (diphenyl phosphate) (BBP) is 15% by mass as a non-halogen flame retardant, and the rubber component is 0.6%. 10% by mass of impact-resistant polystyrene resin (HIPS) having a rubber concentration of 6% by mass and 25% by mass of GP685 (manufactured by PS Japan Co., Ltd.) as a general-purpose polystyrene resin (PS) so as to be mass%, are added to the extruder. Then, the mixture was extruded after heating and melt-kneading to produce base resin pellets. According to the method described in Example 1 of JP-A-4-372630, the base resin pellets are accommodated in a pressure-resistant container, the gas in the container is replaced with dry air, and then carbon dioxide (gas) is injected as a blowing agent. The base resin pellet was impregnated with 7% by weight of carbon dioxide over a period of 3 hours under the conditions of pressure 3.2 MPa and temperature 11 ° C., and the base blade pellet was rotated in a foaming furnace at 77 rpm. While foaming with pressurized steam. The foamed beads were pressurized to 0.5 MPa over 1 hour, then held at 0.5 MPa for 8 hours, and subjected to pressure treatment. This was filled into an in-mold molding die having water vapor holes, heated with pressurized steam to expand and fuse the expanded beads, cooled, and taken out from the molding die. The flame retardancy of this foam was V-0. Using this, performance evaluation as a foam for a secondary battery was carried out, and the results were excellent in electrolytic solution resistance, heat insulation, component fixing performance, and safety (Table 1).
［実施例２］
発泡倍率を表１に示したとおり変更した以外は実施例１と同様にして評価を行った。実施例１と同様に優れた性能を示した（表１）。
[Example 2]
Evaluation was performed in the same manner as in Example 1 except that the expansion ratio was changed as shown in Table 1. The same excellent performance as in Example 1 was shown (Table 1).
［実施例３、４］
各成分の組成、又は発泡倍率を表１に示したとおり変更した以外は実施例１と同様に評価を行った。ポリフェニレンエーテル系樹脂の比率が４５質量％でも実施例１と同様に優れた性能を示した（実施例３）。ポリフェニレンエーテル系樹脂の比率を６０質量％に上げても、優れた性能を示した（実施例４）。
[Examples 3 and 4]
Evaluation was performed in the same manner as in Example 1 except that the composition of each component or the expansion ratio was changed as shown in Table 1. Even when the ratio of the polyphenylene ether-based resin was 45% by mass, excellent performance was shown as in Example 1 (Example 3). Even when the ratio of the polyphenylene ether resin was increased to 60% by mass, excellent performance was shown (Example 4).
［実施例５］
ＨＩＰＳをゴム濃度が１５質量％のものに変更し、各成分の組成、又は発泡倍率を表１に示したとおり変更した以外は実施例１と同様に評価を行った。ゴム成分の組成を３質量％まで高くした場合も優れた性能を示した。
[Example 5]
Evaluation was performed in the same manner as in Example 1 except that the HIPS was changed to a rubber concentration of 15% by mass and the composition of each component or the expansion ratio was changed as shown in Table 1. Even when the composition of the rubber component was increased to 3% by mass, excellent performance was exhibited.
［実施例６〜１４］
難燃剤をトリフェニルホスフェート（ＴＰＰ）に、及びＨＩＰＳをゴム濃度が１９質量％のものに変更し、各成分の組成、又は発泡倍率を表１に示したとおり変更した以外は実施例１と同様に評価を行った。種々の難燃剤添加量（実施例６、７、８）、発泡倍率（実施例９）、ゴム成分量（実施例１０）、ポリフェニレンエーテル系樹脂比率（実施例１１、１２）においても、電解液耐性、断熱性、部品固定性能、安全性、どの性能も低下することはなかった。一方、ポリフェニレンエーテル系樹脂の比率を低くした場合（実施例１３）、難燃性がやや低下する傾向にあるが、実使用には問題のないレベルであった。また、ＢＢＰとＴＰＰと併用しても、各種性能に問題はなかった（実施例１４）。
[Examples 6 to 14]
Example 1 except that the flame retardant was changed to triphenyl phosphate (TPP), the HIPS was changed to a rubber concentration of 19% by mass, and the composition of each component or the expansion ratio was changed as shown in Table 1. Was evaluated. Also in various flame retardant addition amounts (Examples 6, 7, and 8), expansion ratio (Example 9), rubber component amounts (Example 10), and polyphenylene ether resin ratios (Examples 11 and 12), the electrolyte solution Resistance, heat insulation, component fixing performance, safety, and any performance did not deteriorate. On the other hand, when the ratio of the polyphenylene ether-based resin was lowered (Example 13), the flame retardancy tended to be slightly lowered, but it was at a level causing no problem in actual use. Moreover, even if it used together with BBP and TPP, there was no problem in various performance (Example 14).
［実施例１５］
ポリカーボネート系樹脂（ＰＣ）としてＦＰＲ３０００（三菱エンジニアリングプラスチックス（株）製）を８５質量％、非ハロゲン系難燃剤としてビスフェノールＡ−ビス（ジフェニルホスフェート）（ＢＢＰ）を１５質量％に変更した以外は実施例１と同様に評価を行った。基材樹脂にポリカーボネート系樹脂を使用した場合、ポリフェニレンエーテル系樹脂を用いた場合に比べ電解液耐性にやや劣るものの、実使用上特に問題のないレベルであった。また、発泡倍率が低い影響で断熱性にやや劣る結果ではあるが、外気温の影響を低減する効果が十分得られるレベルであった。（表１）。
[Example 15]
Implemented except that FPR3000 (Mitsubishi Engineering Plastics Co., Ltd.) is 85% by mass as polycarbonate resin (PC), and bisphenol A-bis (diphenyl phosphate) (BBP) is changed to 15% by mass as non-halogen flame retardant. Evaluation was performed in the same manner as in Example 1. When a polycarbonate resin was used as the base resin, the electrolyte solution resistance was slightly inferior to that when a polyphenylene ether resin was used, but the level was not particularly problematic in actual use. Moreover, although it was a result inferior to heat insulation by the influence of low foaming ratio, it was a level which can fully obtain the effect of reducing the influence of external temperature. (Table 1).
［実施例１６］
ポリカーボネート系樹脂（ＰＣ／ＡＢＳ）としてＭＢ３８００（三菱エンジニアリングプラスチックス（株）製）に変更した以外は実施例１５と同様に評価を行った所、電解液耐性は実施例１５と同様であった以外は、ポリフェニレンエーテル系樹脂を用いた場合と同等の性能であった。（表１）。
[Example 16]
Except that the polycarbonate resin (PC / ABS) was changed to MB3800 (manufactured by Mitsubishi Engineering Plastics Co., Ltd.), the evaluation was made in the same manner as in Example 15, except that the electrolyte resistance was the same as in Example 15. Was the same performance as when a polyphenylene ether resin was used. (Table 1).
［比較例１〜５］
表２に示す各成分の組成、又は発泡倍率で実施例１と同様に評価を行った。なお、ＨＩＰＳはゴム濃度１９重量％のものを用いた。ポリフェニレン系樹脂組成物の比率が低い場合、低発泡倍率においても難燃性はＶ−２にも満たず、安全性に欠ける結果となった（比較例１）。逆に、ポリフェニレンエーテル系樹脂比率が高すぎると、基材樹脂ペレット作成時の押出において熱劣化による異物が多発し、評価に値する発泡体が得られなかった（比較例２）。難燃剤の量が少なすぎると難燃性が殆ど発現せず（比較例３）、多すぎると、発泡ビーズの独立気泡率が大幅に低下し、成形品が得られなかった（比較例４）。ゴム成分を全く用いなかった場合、樹脂の柔軟性、伸び不足によるセル膜の破膜が発生し、成形加工性が低下してしまい、良好な成形品が得られなかった（比較例５）。
[Comparative Examples 1-5]
Evaluation was performed in the same manner as in Example 1 using the composition of each component shown in Table 2 or the expansion ratio. HIPS having a rubber concentration of 19% by weight was used. When the ratio of the polyphenylene resin composition was low, the flame retardancy was less than V-2 even at a low expansion ratio, resulting in lack of safety (Comparative Example 1). On the other hand, if the polyphenylene ether-based resin ratio is too high, foreign matters due to thermal deterioration frequently occur during extrusion during the production of the base resin pellets, and a foam worthy of evaluation cannot be obtained (Comparative Example 2). If the amount of the flame retardant is too small, the flame retardancy is hardly exhibited (Comparative Example 3). If the amount is too large, the closed cell ratio of the expanded beads is greatly reduced, and a molded product cannot be obtained (Comparative Example 4). . When the rubber component was not used at all, the cell membrane was broken due to the flexibility of the resin and insufficient elongation, and the molding processability was lowered, and a good molded product was not obtained (Comparative Example 5).
［比較例６〜７］
表２に示す各成分の組成において未発泡の樹脂を加熱プレスで成形した以外は実施例１と同様に評価を行った。未発泡樹脂としてポリフェニレンエーテル系樹脂Ｓ２０１Ａ（旭化成ケミカルズ（株）製）を使用した場合は、電解液耐性や安全性は良好なものの、断熱性は全く発揮されなかった。また、部品固定性能についても、発泡体のような柔軟さに欠けるため、ロの字型のサンプル内にファンを挿入する事ができなかった（比較例６）。ポリカーボネート系樹脂ＭＢ３８００（三菱エンジニアリングプラスチックス（株）製）を使用した場合も同様の結果となった（比較例７）。
[Comparative Examples 6-7]
Evaluation was performed in the same manner as in Example 1 except that an unfoamed resin was molded by a hot press in the composition of each component shown in Table 2. When polyphenylene ether resin S201A (Asahi Kasei Chemicals Co., Ltd.) was used as the unfoamed resin, the heat resistance was not exhibited at all, although the electrolyte resistance and safety were good. Moreover, since the component fixing performance was not as flexible as a foam, it was not possible to insert a fan into the square-shaped sample (Comparative Example 6). The same result was obtained when polycarbonate resin MB3800 (manufactured by Mitsubishi Engineering Plastics Co., Ltd.) was used (Comparative Example 7).
本発明の発泡体は、リチウムイオン電池等の二次電池の電池保持材や断熱材として好適である。さらに、リチウムイオンキャパシタ等、他の蓄電媒体についても、断熱材として好適に使用できる。 The foam of the present invention is suitable as a battery holding material or a heat insulating material for a secondary battery such as a lithium ion battery. Furthermore, other power storage media such as lithium ion capacitors can be suitably used as heat insulating materials.
