Description
本発明は、ストラットマウントの製造に好適に使用することができる発泡ウレタン組成物に関する。 The present invention relates to a urethane foam composition that can be suitably used for manufacturing a strut mount.
ストラットマウントは、コイルスプリングとショックアブソーバーとを車体に支持する部材であり、路面からの衝撃を緩和し、振動や騒音の伝達を抑える機能を有するものである。前記ストラットマウントのハウジングの内部充填剤としては、ゴムや発泡ウレタンが使用されている。前記内部充填剤としてゴムが使用された場合には、振動減衰が劣り、衝撃を受けた後いつまでも揺れが継続してしまうとの欠点を有する。これに対し、発泡ウレタンは低弾性と振動減衰とのバランスに優れるため、ゴムから発泡ウレタンへの置換が進んでいる（例えば、特許文献１を参照。）。 The strut mount is a member that supports the coil spring and the shock absorber on the vehicle body, and has a function of reducing the impact from the road surface and suppressing the transmission of vibration and noise. Rubber or urethane foam is used as an internal filler for the housing of the strut mount. When rubber is used as the internal filler, vibration damping is inferior, and there is a disadvantage that shaking continues for a long time after receiving an impact. On the other hand, since urethane foam is excellent in the balance between low elasticity and vibration damping, replacement of rubber with urethane foam is progressing (see, for example, Patent Document 1).
しかしながら、現行の発泡ウレタンは、ハンドル操作時の車挙動のフィーリングに影響する静的バネ定数を一定量確保すると、瞬間的な衝撃を吸収する柔軟さを示す動的バネ定数が高くなるため、動倍率が高くなり、衝撃を吸収しきれないとの問題点があった。 However, the current foamed urethane has a high dynamic spring constant that indicates the flexibility to absorb instantaneous impact, if a certain amount of static spring constant that affects the feeling of vehicle behavior during steering operation is secured. There was a problem that the dynamic magnification became high and the shock could not be absorbed.
本発明が解決しようとする課題は、動倍率、及び、貯蔵弾性率の周波数依存性を低減化する発泡ウレタン組成物を提供することである。 The problem to be solved by the present invention is to provide a urethane foam composition that reduces the frequency dependence of dynamic magnification and storage modulus.
本発明は、ポリエーテルポリエステルポリオール（ａ−１）及び１，５−ナフタレンジイソシアネート（ａ−２）の反応物であるイソシアネート基を有するウレタンプレポリマー（Ａ）と活性水素原子を有する化合物（Ｂ）と水（Ｃ）とを含有することを特徴とする発泡ウレタン組成物、及び、その硬化物を有することを特徴とするストラットマウントを提供するものである。 The present invention relates to a urethane prepolymer (A) having an isocyanate group which is a reaction product of a polyether polyester polyol (a-1) and 1,5-naphthalene diisocyanate (a-2) and a compound (B) having an active hydrogen atom. The present invention provides a urethane foam composition characterized by containing water and water (C), and a strut mount characterized by having a cured product thereof.
本発明の発泡ウレタン組成物の硬化物は、適度な密度及び硬度を有し、かつ、動倍率及び貯蔵弾性率の周波数依存性が低いため、優れた衝撃吸収能を有する。よって、本発明の発泡ウレタン組成物は、光学用部材、自動車部材、土木建築用部材等の様々な分野で利用可能であり、緩衝材、ベアリング、ストラットマウント、バンプクッション等の制振用部材として好適に使用することができ、ストラットマウントのハウジングの内部充填剤として特に好適に用いることができる。 The cured product of the urethane foam composition of the present invention has an appropriate density and hardness, and has a low impact frequency and dependence on the dynamic modulus and storage elastic modulus, and thus has an excellent impact absorbing ability. Therefore, the urethane foam composition of the present invention can be used in various fields such as optical members, automobile members, civil engineering and building materials, and is used as a damping member for cushioning materials, bearings, strut mounts, bump cushions, and the like. It can be used preferably, and can be particularly preferably used as an internal filler of the housing of the strut mount.
本発明の発泡ウレタン組成物は、ポリエーテルポリエステルポリオール（ａ−１）及び１，５−ナフタレンジイソシアネート（ａ−２）を反応させて得られるイソシアネート基を有するウレタンプレポリマー（Ａ）と活性水素原子を有する化合物（Ｂ）と水（Ｃ）とを必須成分として含有するものである。 The urethane foam composition of the present invention comprises a urethane prepolymer (A) having an isocyanate group obtained by reacting a polyether polyester polyol (a-1) and 1,5-naphthalene diisocyanate (a-2) and an active hydrogen atom. A compound (B) having water and water (C) are contained as essential components.
前記ポリエーテルポリエステルポリオール（ａ−１）は、動倍率及び貯蔵弾性率の周波数依存性の低減化に必須の成分である。前記ポリエーテルポリエステルポリオール（ａ−１）の代わりに他のポリオールを用いた場合には、動的バネ定数、及び、高周波数領域での貯蔵弾性率が高くなり、衝撃吸収能が低下してしまう。 The polyether polyester polyol (a-1) is an essential component for reducing the frequency dependence of dynamic magnification and storage elastic modulus. When another polyol is used instead of the polyether polyester polyol (a-1), the dynamic spring constant and the storage elastic modulus in the high frequency region are increased, and the impact absorption capacity is decreased. .
前記ポリエーテルポリエステルポリオール（ａ−１）としては、例えば、ポリエーテルポリオール（ａ−１−１）とラクトン化合物（ａ−１−２）とを公知の方法により反応させて得られたものを用いることができる。 As said polyether polyester polyol (a-1), what was obtained by making polyether polyol (a-1-1) and a lactone compound (a-1-2) react by a well-known method is used, for example. be able to.

Methylene polyol or the like can be used. These polyether polyols may be used alone or in combination of two or more. Among these, it is preferable to use polytetramethylene glycol because the frequency dependence of the dynamic magnification and the storage elastic modulus can be further reduced.
前記ラクトン化合物（ａ−１−２）としては、例えば、δ−バレロラクトン、β−メチル−δ−バレロラクトン、ε−カプロラクトン、β−メチル−ε−カプロラクトン、γ−メチル−ε−カプロラクトン、β，δ−ジメチル−ε−カプロラクトン、３，３，５−トリメチル−ε−カプロラクトン、エナントラクトン、ドデカノラクトン等を用いることができる。これらの化合物は単独で用いても２種以上を併用してもよい。 Examples of the lactone compound (a-1-2) include δ-valerolactone, β-methyl-δ-valerolactone, ε-caprolactone, β-methyl-ε-caprolactone, γ-methyl-ε-caprolactone, β , Δ-dimethyl-ε-caprolactone, 3,3,5-trimethyl-ε-caprolactone, enanthlactone, dodecanolactone, and the like can be used. These compounds may be used alone or in combination of two or more.
前記ポリエーテルポリエステルポリオール（ａ−１）としては、動倍率及び貯蔵弾性率の周波数依存性をより一層低減化できる点から、ポリテトラメチレングリコールとラクトン化合物とを反応させて得られるポリオールを用いることが好ましく、ポリテトラメチレンポリオールとε−カプロラクトンとを反応させて得られるポリオールを用いることがより好ましい。 As the polyether polyester polyol (a-1), a polyol obtained by reacting polytetramethylene glycol and a lactone compound is used from the viewpoint that the frequency dependency of dynamic magnification and storage modulus can be further reduced. It is preferable to use a polyol obtained by reacting polytetramethylene polyol with ε-caprolactone.
前記ポリエーテルポリエステルポリール（ａ−１）の数平均分子量としては、動倍率及び貯蔵弾性率の周波数依存性の点から、６５０〜５，０００の範囲であることが好ましく、８００〜４，０００の範囲がより好ましく、１，０００〜３，０００の範囲が更に好ましい。なお、前記ポリエーテルポリエステルポリール（ａ−１）の数平均分子量は、ゲル・パーミエーション・クロマトグラフィー（ＧＰＣ）法により、下記の条件で測定した値を示す。 The number average molecular weight of the polyether polyester polyol (a-1) is preferably in the range of 650 to 5,000 from the viewpoint of frequency dependence of dynamic magnification and storage modulus, and is preferably 800 to 4,000.
