【発明の詳細な説明】
（産業上の利用分野）
本発明は、巾広い温度範囲において優れた割振特性を発
揮するエポキシ樹脂系の制振材に間する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an epoxy resin-based vibration damping material that exhibits excellent damping characteristics over a wide temperature range.

を発揮させたものが多用されている。(Prior art) Conventionally, by adding various fillers to rubber and plastic as materials for damping materials, it has been possible to obtain a good jig ratio and loss coefficient, and to adjust the damping coefficient ratio (C/Cc) well. death,
Those that exhibit a vibration damping effect by converting vibration energy into thermal energy are often used.

酸化マグネシウム、酸化チタン等がある。Such rubbers and plastics include vinyl chloride resin, epoxy resin, ethylene-vinyl acetate copolymer, neorene rubber, polychloroprene rubber, etc., and fillers include particulate, flaky, fibrous, etc. Ferrite, graphite, mica, aluminum, with shapes
Examples include magnesium oxide and titanium oxide.
しかしながら、これら従来の制振材料は温度による減衰
係数比の変化が大きく、それぞれ特定の狭い温度領域で
しかその制振効果を充分に発揮できないという欠点を有
している。これは、それぞれの材料が持つ損失係数（ｔ
ａｎδ〉が、その材料固有のガラス転移点（Ｔｇ）を中
心として狭い温度範囲のピークを有するためである。However, these conventional damping materials have the disadvantage that their damping coefficient ratios vary greatly depending on temperature, and that they can only fully exhibit their damping effects within a specific narrow temperature range. This is the loss coefficient (t
This is because an δ> has a peak in a narrow temperature range around the glass transition point (Tg) specific to the material.
そこで、樹脂に可塑剤を配合してガラス転移点を移動す

広げる、即ちｔａｎδのピークを広げることはできなか

とはできるものの、このような相状態を一定に保持るこ
とは非常に難しく、製造ロットによる制振特性のばらつ
きが大きくなるという欠点を有している。Therefore, attempts have been made to shift the glass transition point by adding a plasticizer to the resin, but it has not been possible to widen the temperature range with good allocation characteristics, that is, to broaden the tan δ peak. In addition, a technique is known in which two types of polymer materials are mixed in a liquid or molten state, but if the mixed state is completely compatible, tan δ will have a single peak approximately halfway between the respective glass transition points. Therefore, the temperature Iig! with good allocation characteristics is obtained. Furthermore, if the mixed state is a phase-separated state, it is possible to have both tan δ peaks and widen the temperature range R for good Mwg characteristics, but it is not possible to keep such a phase state constant. It is very difficult to maintain the damping characteristics, and has the drawback that the vibration damping characteristics vary greatly depending on the production lot.
