［産業上の利用分野コ
本発明は、可撓性を有する膨張部材に関するものである
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a flexible expansion member.
［従来の技術］
可撓性膨脹部材は、従来からパツキンやクツション材等
として幅広く用いられている。[Prior Art] Flexible inflatable members have been widely used as packing materials, cushioning materials, and the like.

縮し接合部に間隙が生じるともはやパツキンとしての機
ｆ七を果たさなくなる。Cushioning material is something that cushions impact, and either does not transmit vibrations from one side to the other side or significantly reduces them. Well, there are also things that make both sides vibrate in the same way. That is, if they vibrate separately, a shock is generated, which may cause damage or noise. When used in such applications, it is necessary to follow the expansion of each part as the temperature rises, without creating gaps, and to also have heat resistance. It is an essential requirement to have elasticity to fill the gaps in the
Heat resistance and pressure resistance may be required depending on the place of use. However, even if it has good sealing properties at room temperature, it cannot be used if it is damaged or hardened at high temperatures and loses its sealing properties or deteriorates significantly. That is, if the volume contracts at high temperatures and gaps are created at the joint, it no longer functions as a packing.
また、クツシラン材としても２．高温時に収縮したり、
各部の膨張に追従できないものでは用をなさない。It can also be used as a kutsushiran material. Shrinks at high temperatures,
It is useless if it cannot follow the expansion of each part.

高い（７００〜８００℃）。よって、触媒の金属容器等
の膨張も大きい。In such a practical application, the M of automobile exhaust gas is
There are cushioning materials (filling materials) for media converters. Here, a catalyst with a ceramic or resin carrier is used due to heat resistance issues, so it is fragile to vibrations, so it is necessary to suppress impact as much as possible. Furthermore, since the combustion exhaust gas from the engine passes through it, its temperature is very high (700 to 800°C). Therefore, the expansion of the catalyst metal container and the like is also large.
このような用途に最適のものとして、従来からバーミキ

時に膨張し各部材の膨張に追従し間隙を生じないという
優れたものである。Conventionally, the most suitable material for such uses is a sheet made by bonding vermiculite and an inorganic material with a binder. Since it is an inorganic material, it has high heat resistance, and since it contains vermiculite, it expands at high temperatures and follows the expansion of each member, making it excellent in that it does not create gaps.

た、フェルト状であるため強度が小さいという問題点も
あり、且つ細く成型するき保形性がなく使用できない。[Problems to be Solved by the Invention] However, in the conventional products as described above, since the sheet-like body is hard, it is difficult to wrap the sheet-like body around a cylindrical body. In addition, since it is felt-like, it has a problem of low strength, and it cannot be used because it cannot be molded into a thin shape and does not retain its shape.
同様の構造のものをパツキンとして使用する場合にも、
フェルト状であり脆いため、締め付けと脱離を繰り返す

される箇所等では、実用−Ｌは、繰り返しの使用ができ
ないという欠点があった。When using a similar structure as a packing,
Since it is felt-like and brittle, repeated tightening and detachment will cause it to gradually peel off and break off, so Practical-L has the disadvantage that it cannot be used repeatedly in places where high sealing performance is required.

のである点にある。1] Means for Solving the Problems In view of the above-mentioned current situation, the present invention has completed the flexible inflatable member of the present invention as a result of intensive research, and its characteristics are as follows: The main feature is that vermiculite 1- in the form of unfoamed powder is sandwiched between the core of a cylindrical body made of knitted and woven material.
ここで、無機繊維とは、ガラス繊維、セラミック繊維等
をいい通常のものでよい。また、石綿も使用できるが、
安全性の点で問題がある。Here, the inorganic fibers refer to glass fibers, ceramic fibers, etc., and may be ordinary fibers. Asbestos can also be used, but
There is a problem in terms of safety.

力はない。This vermiculite can be heated (from about 400″C)
Then, it has the property of foaming and expanding. That is, it expands several times to about 30 times on the C axis of the layered structure. Of course, if there is a metal container etc. around it, there will not be enough expansion force to destroy it.
このバーミキュライトを粉末状にするが、サイズは５０
〜１００メツシュ程度が好適である。This vermiculite is made into a powder, but the size is 50
Approximately 100 meshes is suitable.
編織とは、編むことと織ることを含めた概念として使用

る。The core is inserted into the center of the cylindrical body, and corresponds to the lead of a pencil if the cylindrical body is the wooden part of a pencil. Vermiculite is used with this core.Of course, it is not limited to vermiculite alone, and other materials may be mixed.For example, inorganic short fibers and other aggregates (such as perlite) are used. ).
また、バーミキュライトの粉末は接着剤に分散させたも
のでも、無機の粘着剤等に混合したものでもよい。Further, the vermiculite powder may be dispersed in an adhesive or mixed in an inorganic adhesive or the like.
本発明の可撓性腫脹部材の製造において、未発泡の粉末

では、製造の効率がよく編み上げと同時に充填が完了す
る。First, in the method of knitting and manufacturing a cylindrical body, U
& This is a method of filling the fibers while knitting them. for example,
This is a method in which vermiculite powder is dropped from both sides of the process of constructing a bag by knitting it into a cylindrical shape. This method is highly efficient in manufacturing and completes filling at the same time as knitting.
他の方法は、芯部を、繊維をクロス状に編＾６だもので
巻き込み接合部を縫製する方法である。例えば、バーミ
キュライトをクロスの中心付近に棒状に載置してクロス
を巻いて接合部を縫うのである。この方法の場合には、
特別な装置を準備する必要がなく簡単に実施できる。Another method is to wrap the core in a cross-knit fabric of fibers and sew the joint. For example, a bar of vermiculite is placed near the center of the cloth, the cloth is wound, and the joints are sewn. In this method,
It can be easily implemented without the need to prepare special equipment.
バーミキュライトの充填量（巻き込みｌ）としては、無
機繊維１００重量部にたいして２０〜１５０重量部稈度
が好適である。The filling amount of vermiculite (inclusion 1) is preferably 20 to 150 parts by weight per 100 parts by weight of inorganic fibers.
編織した筒状体に、通常のグランドパツキンとして用い

ある。即ち、油、グリース等をしみ込ませるか、黒鉛を
塗布する等である。It is also suitable for the woven cylindrical body to contain lubricating oil that is applied to a string-like body used as a normal gland packing. That is, it is impregnated with oil, grease, etc., or coated with graphite.
［実施例］
セラミック繊維１００重量部に対して、バーミキュライ
トが７０重量部になるように、繊維（糸）を袋編みする
工程で、上方から充填して紐状体を製造した。[Example] A string-like body was manufactured by filling fibers (threads) from above in a bag knitting process such that vermiculite was 70 parts by weight based on 100 parts by weight of ceramic fibers.
このものをパツキンとして高温ドア部の開口部に使用し
、高温り７００℃）にして実験したところパツキンの硬
化収縮による漏洩はまったくなかった。When this material was used as a gasket in the opening of a high-temperature door section and tested at a high temperature of 700° C., there was no leakage due to curing and shrinkage of the gasket.
さらに、−度常温にし再度昇温した場合にも漏洩はみら
れなかった。Furthermore, no leakage was observed even when the temperature was raised again after being brought to room temperature by - degrees.
本例の紐状体を、前記説明した自動車の触媒コンバータ
ーに使用したが、この場合においても、可撓性が大きい
ため非常に装着しやすく、かつ温度が上がった後におい
ても間隙は生じなかった。The string-like body of this example was used in the above-mentioned automobile catalytic converter, and in this case as well, it was very easy to install due to its great flexibility, and no gaps were formed even after the temperature rose. .
