従来より、電子回路基板や電子部品は、外部からの汚染を防ぐためにポリウレタン樹脂等を用いて封止することが行われている（特許文献１）。また、近年、ＬＳＩ等に見られるように、電子回路の集積化、小型化及び高機能化によって電子回路基板上の発熱量が局所的に増大しているため、ポリウレタン樹脂は高温条件下に曝されている。このような高温条件下における硬度変化を低減するために、ポリオール成分としてポリブタジエンポリオールの水素添加物や、ポリイソプレンの水素添加物の使用が検討されている（例えば、特許文献２）。また、発生する熱をより効率的に外部に放出する必要性が高くなっていることから、これらのポリウレタン樹脂には、多量の無機充填材が配合されているのが通常である。 Conventionally, electronic circuit boards and electronic components have been sealed using polyurethane resin or the like in order to prevent external contamination (Patent Document 1). In recent years, as seen in LSIs and the like, the amount of heat generated on an electronic circuit board is locally increased due to the integration, miniaturization, and higher functionality of electronic circuits. Has been. In order to reduce the change in hardness under such high temperature conditions, the use of a hydrogenated polybutadiene polyol or a hydrogenated polyisoprene as a polyol component has been studied (for example, Patent Document 2). Moreover, since the necessity to discharge | release generated heat | fever more efficiently outside is high, it is normal that a large amount of inorganic fillers are mix | blended with these polyurethane resins.
しかしながら、多量の無機充填材を配合したポリウレタン樹脂を製造する場合、硬化前のポリウレタン樹脂組成物の段階で粘度が大きくなるため、十分に混合することができず、均一なポリウレタン樹脂を得ることができなくなるという問題がある。ポリウレタン樹脂組成物の混合が不十分な場合、均一なポリウレタン樹脂を得ることができなくなり、放熱性を長期間にわたって維持することができないという問題がある。
本発明は上記従来技術に鑑みて為されたものであり、本発明の目的は、粘度低下により十分な混合が可能で、硬化後において優れた放熱性と可撓性を長期間にわたって維持し得るポリウレタン樹脂組成物、及びこれを硬化させたポリウレタン樹脂を提供することである。 The present invention has been made in view of the above prior art, and an object of the present invention is that sufficient mixing is possible due to a decrease in viscosity, and excellent heat dissipation and flexibility after curing can be maintained over a long period of time.

本発明のポリウレタン樹脂組成物では、ポリオール成分として（Ｂ）ひまし油系ポリオールの水素添加物が配合されているため、無機充填材が多量に配合されていても混合時の粘度が増大せず、均一に混合することが可能となっている。 In the polyurethane resin composition of the present invention, since a hydrogenated product of (B) castor oil-based polyol is blended as a polyol component, even when a large amount of inorganic filler is blended, the viscosity at the time of mixing does not increase and is uniform. Can be mixed.

＜試験結果＞
実施例１〜７のポリウレタン樹脂組成物は、何れも混合可能な粘度であった。特に、リン酸エステルを配合した場合には、より低粘度となった。一方、比較例３のポリウレタン樹脂組成物は混合可能な粘度ではあったが、比較例１及び２の組成物は粘度が非常に高く、混合か不可能となり、均一なポリウレタン樹脂を得ることができなかった。
<Test results>
The polyurethane resin compositions of Examples 1 to 7 all had a mixable viscosity. In particular, when a phosphate ester was blended, the viscosity became lower. On the other hand, the polyurethane resin composition of Comparative Example 3 had a viscosity that could be mixed, but the compositions of Comparative Examples 1 and 2 had a very high viscosity, making mixing impossible, and a uniform polyurethane resin could be obtained. There wasn't.
また、実施例１〜７のポリウレタン樹脂は、何れも熱伝導率が高く、十分な放熱性を有していることが分かる。 In addition, it can be seen that the polyurethane resins of Examples 1 to 7 all have high heat conductivity and sufficient heat dissipation.
更に、実施例１〜７のポリウレタン樹脂は、耐熱性試験後においても硬度がほとんど変化しておらず、耐熱性に優れていることが分かる。一方、比較例３のポリウレタン樹脂は、耐熱性試験後において大幅な硬度上昇が見られることが分かる。 Furthermore, it can be seen that the polyurethane resins of Examples 1 to 7 have almost no change in hardness even after the heat resistance test and are excellent in heat resistance. On the other hand, it can be seen that the polyurethane resin of Comparative Example 3 shows a significant increase in hardness after the heat resistance test.
本発明のポリウレタン樹脂組成物は、低粘度で十分な混合が可能であり、高温条件下における硬度変化が小さいことから長期間にわたって基材に十分密着し、発生する多量の熱を外部に放出し得るポリウレタン樹脂が得られるので、電気製品、電子部品等の分野で利用が可能である。 The polyurethane resin composition of the present invention has a low viscosity and can be sufficiently mixed. Since the change in hardness under high temperature conditions is small, the polyurethane resin composition sufficiently adheres to the substrate over a long period of time and releases a large amount of generated heat to the outside. Since the obtained polyurethane resin is obtained, it can be used in the fields of electrical products, electronic parts and the like.
