う問題があった。These sealing materials harden after installation and fill the sealing areas between metals or between refractories and metals to ensure sealing performance. Yes, and expansion due to temperature changes,
Contraction always occurs, and conventionally used inorganic sealants cannot sufficiently absorb expansion and contraction, causing the seal to peel or crack, resulting in a loss of sealing performance. .

なかった。[Problems to be solved by the invention] There are no conventional inorganic sealing materials that can be stably used for long periods of time in sealing areas that expand and contract in high-temperature areas. I couldn't get it.
本発明者等は、上述問題点を解決すべく検討した結果、
熱放散性のよい材料と高温下でも固化しない可撓性材料

できる耐熱性シール材を開発するに至った。As a result of studies to solve the above-mentioned problems, the inventors of the present invention found that
By mixing a material with good heat dissipation and a flexible material that does not harden even at high temperatures, we have developed a heat-resistant sealing material that can achieve the desired purpose.
本発明はこのようなシール材を提供することを目的とす

［作用］
本発明は高温部からの熱をできるかぎり速やかに低温部
に放散することによって、耐熱性ゴム（シリコン樹脂）
を安定な温度に保ち、ゴムの劣化を防ぐものである。[Function] The present invention dissipates heat from a high-temperature part to a low-temperature part as quickly as possible, thereby reducing heat-resistant rubber (silicon resin).
This is to keep the rubber at a stable temperature and prevent the rubber from deteriorating.
シリコン樹脂および充填剤はシール材としての機能を維
持するためのものであり、その弾性を維持し、且つ耐熱
性を確保するために、熱放散性のよい粉体として一定の
粒度と特定の成分を一定量添加するものである。The silicone resin and filler are used to maintain their function as a sealing material, and in order to maintain their elasticity and ensure heat resistance, they are made into a powder with a certain particle size and specific ingredients with good heat dissipation properties. is added in a certain amount.
シリコン樹脂はシール材に弾性を与えるもので、２０重
量％未満では弾性が不足し、シール効果が発揮できない
、また、４０重量％を超える添加では、耐熱性の点で問
題があり、１５０℃を超える高温域での使用の際、寿命
が短くなる。従って、２０〜４０重量％とじた。Silicone resin gives elasticity to the sealing material, and if it is less than 20% by weight, the elasticity is insufficient and the sealing effect cannot be achieved.If it is added in excess of 40% by weight, there is a problem with heat resistance, and it cannot be heated to 150℃. When used in high temperature ranges, the lifespan will be shortened. Therefore, it was reduced to 20 to 40% by weight.
充填剤は増量、粘度調整、老化（劣化）防止などのため
に使用されるもので、前記シリコン樹脂の使用上のたれ
防止のための粘度調整および切れをよくするためには２
０重量％以上が必要であり、４０重量％を超えると、シ
リコン樹脂の弾性力が不足することになり、望ましくな
い、従って２０〜４０重量％の範囲で調整する。Fillers are used to increase the volume, adjust viscosity, prevent aging (deterioration), etc., and are used to adjust the viscosity to prevent sagging and improve cutting when using the silicone resin.
0% by weight or more is required; if it exceeds 40% by weight, the elasticity of the silicone resin will be insufficient, which is not desirable; therefore, it should be adjusted within the range of 20 to 40% by weight.
熱放散性粉体は１本発明のシール材の最大の特徴である
熱放散を図ることにより、シリコン樹脂および充填材の
熱による劣化を防止するものである。熱放散性をよくす
るためには、添加量としてはできる限り多量添加したい
が１弾性シール材としての機能を害しない範囲に止めな
ければならない。この点から熱放散性粉体は６０重量％
以下の量とされる。また、少なくとも２０重量％以上と
しないと熱放散の効果はでないので、添加量を２０〜６
０重量％とした。なお、熱放散性粉体は粒度が小さけれ
ば表面積が大となり、添加量が多くなるとシール材がボ
ロボロになるので、添加量を少なくする必要があり、粒
度が大きければ添加量を多くすることができる。The heat-dissipating powder prevents the silicone resin and the filler from deteriorating due to heat by dissipating heat, which is the most important feature of the sealing material of the present invention. In order to improve heat dissipation, it is desirable to add as much as possible, but it must be kept within a range that does not impair its function as an elastic sealing material. From this point, the heat dissipating powder is 60% by weight.
The amount shall be as follows. In addition, the heat dissipation effect will not be achieved unless the amount is at least 20% by weight, so the amount added should be 20 to 6% by weight.
It was set to 0% by weight. Furthermore, if the particle size of the heat dissipating powder is small, the surface area will be large, and if the amount added is large, the sealing material will fall apart, so it is necessary to reduce the amount added, and if the particle size is large, it is not possible to increase the amount added. can.
以上の組成によって、適切な熱放散性を維持した耐熱性
弾性シール材を得ることができる。With the above composition, a heat-resistant elastic sealing material that maintains appropriate heat dissipation properties can be obtained.
