次に本発明の実施例について説明する。Next, examples of the present invention will be described.
先づ分子量２０万を中心としたゴム素材（ポリクロロプ
レンゴム及び天然ゴム）と、分子量２千から１万２千迄
のゴム素材（低分子液状ポリクロロプレンゴム及び低分
子液状ＮＢＲ）とを混合した天然ゴム又は合成ゴムを母
体素材として、これに発泡剤、架橋剤、架橋助剤、軟化
剤、老化防止剤等を添加混練し、これに所要の金属成分
化合物を混合精練を行い、これを２４時間放置熟威せし
め、次に所定の金型内に上記未架橋生地を挿入し、加圧
加熱により所定温度に於て、内蔵された発泡剤の分解が
おこり、素材中に気泡因子が発生し、次に架橋反応が進
み、排圧により発砲剤分解時のガス圧と分解熱により当
該素材は膨張して型外にはみ出す。First, a rubber material with a molecular weight of 200,000 (polychloroprene rubber and natural rubber) and a rubber material with a molecular weight of 2,000 to 12,000 (low-molecular liquid polychloroprene rubber and low-molecular liquid NBR) were mixed. Using natural rubber or synthetic rubber as a base material, foaming agents, crosslinking agents, crosslinking aids, softeners, anti-aging agents, etc. are added and kneaded, and the required metal component compounds are mixed and refined. The uncrosslinked dough is left to ripen for a period of time, and then the uncrosslinked dough is inserted into a specified mold, and the built-in foaming agent is decomposed at a specified temperature by pressure heating, and a bubble factor is generated in the material. Next, the crosslinking reaction progresses, and the material expands and protrudes out of the mold due to gas pressure and decomposition heat during decomposition of the foaming agent due to exhaust pressure.
この時型内挿入時の仕込み重量を変化させることによっ
て、閉鎖気泡と開放気泡とをその需要に応じて生産する
ことが出来る。At this time, by changing the charged weight at the time of insertion into the mold, closed cells and open cells can be produced according to the demand.
この様にして産出された気泡体を再び所定の予め用意さ
れた別の金型に挿入して加熱すると未分解ガスが完全に
放出でき、又架橋反応も完結する。When the foam thus produced is again inserted into another predetermined mold and heated, undecomposed gas can be completely released and the crosslinking reaction can be completed.

である。Since the present invention has the above-described configuration, it is possible to produce a foam containing a large amount of metal components, and conventionally, when such a large amount of metal components is included, a scorch phenomenon occurs, making production difficult. However, in the present invention, by incorporating and mixing a liquid polymer with a molecular weight of 2,000 to 12,000, the frictional heat with the metal powder is reduced, and the dispersion of these additives becomes uniform.
Sintering has extremely remarkable effects, such as preventing this phenomenon and providing highly elastic and flexible foams containing desired metal components, which can be applied to a wide variety of fields.
