【考案の詳細な説明】
〈産業上の利用分野〉
本考案は、流体圧装置等において、２つの部材
間に介装されて圧力流体の洩れを防止するシール
リングに関する。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a seal ring that is interposed between two members in a fluid pressure device or the like to prevent leakage of pressure fluid.
〈従来の技術〉
一般にこの種のシールリングは、その取付箇所

いては目視して識別することがむずかしく、誤取
付の原因となる。<Prior art> Generally, this type of seal ring is available in various diameter sizes, from large to small, depending on the installation location, but if the dimensions are similar, it is difficult to visually identify them. This is difficult and can lead to incorrect installation.
このため、従来においては、シールリングの
各々に対して着色ペン等を用いて線を記入し、こ
の線によつてシールリングのサイズを識別してい
る。 For this reason, conventionally, a line is drawn on each seal ring using a colored pen or the like, and the size of the seal ring is identified by this line.

A second glass wool material containing the composition and a coloring agent.
This is a sealing characterized by being made up of a composition.

とができる。<Function> Since the present invention has the above-mentioned configuration, second compositions made of glass wool having different colorant contents are prepared for each size, and in the seal ring molding process, second compositions made of glass wool according to the sizes are prepared. composition first
By mixing it with the composition, seal rings with different colored states depending on their size can be easily manufactured.
〈実施例〉
以下本考案の実施例を図面に基づいて説明す
る。<Example> Hereinafter, an example of the present invention will be described based on the drawings.
先ず本考案のシールリングは、複数種類の組成
物を成形型の間に充填した状態で圧力を加えるこ
とで、図面に示すようにリング状に成形したもの
で、このシールリングがその取付場所に応じて径
サイズの異なるものが多数用意される。 First, the seal ring of the present invention is formed into a ring shape as shown in the drawing by filling multiple types of compositions between molds and applying pressure. A large number of different diameter sizes are available depending on the needs.
このシールリングの組成物としては、４弗化エ

２組成物が用いられる。この第１、第２組成物の
割合はその重量比において第１組成物85％とした
とき、第２組成物15％の割合にて配合するのが適
切である。 As the composition of this seal ring, a first composition consisting of a tetrafluoroethylene resin and a second composition consisting of glass wool added for the purpose of improving wear resistance are used. It is appropriate that the first and second compositions be blended in a weight ratio of 85% for the first composition and 15% for the second composition.
ここにおいて上記グラスウール製第２組成物

状態を各サイズ毎に任意に設定することができ
る。 Here, the second composition made of glass wool contains, in addition to glass wool, a coloring agent such as a pigment for coloring. The second composition has different colored states by changing the content of the colorant. Therefore, by preparing a wide variety of second compositions with different colorant contents and using them properly, the coloring state of the entire seal ring can be arbitrarily set for each size.
なお、上記着色剤は第１組成物を構成する４弗
化エチレン樹脂に対して直接添加すると、この樹
脂の強度低下をもたらす。 Note that when the above-mentioned coloring agent is directly added to the tetrafluoroethylene resin constituting the first composition, the strength of this resin is reduced.
しかるに本考案では予め第２組成物に着色剤を
含有させておき、その後この第１、第２組成物を

色剤をグラスウールに添加することでグラスウー
ルが前記４弗化エチレン樹脂に対し耐摩耗性向上
剤として機能するのみで、着色剤による悪影響す
なわち強度低下の問題はなくなる。 However, in the present invention, the second composition contains a coloring agent in advance, and then the first and second compositions are mixed together. By adding a coloring agent to the glass wool in advance in this manner, the glass wool only functions as an abrasion resistance improver for the tetrafluoroethylene resin, and the problem of the adverse effects of the colorant, that is, a decrease in strength, is eliminated.

を有する。<Effects of the invention> As detailed above, in the present invention, the oil seal is composed of the first composition made of tetrafluoroethylene resin and the second composition made of glass wool containing a colorant. When manufacturing oil seals from the composition and the second composition, by appropriately using the second composition mixed with a coloring agent, it is possible to color-code the seal ring according to its size, and in the final process, it is possible to color-code the seal ring by hand. It has the advantage that it can be easily colored in the manufacturing process of the composition without being colored, making mass production possible and reducing manufacturing costs.
