パッキングに関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to sheet packing, and more specifically to sealing members for various industrial equipment, such as gaskets for cylinder heads of automobile internal combustion engines, backings for joints of various pipes, etc. The present invention relates to sheet packing that is highly heat resistant and can be manufactured at low cost.
周知の通り上述した各産業機器、装置のシール部分には
、はとんどシートバンキングが用いられている。As is well known, sheet banking is generally used for the sealing parts of the above-mentioned industrial equipment and devices.
この場合、以前に於いては、その断面構造が単−の層よ

ッキングの主要な特性の１つであるスプリング性（弾復
元性）に富むとの理由で、次の技術が用いられている。In this case, sheet packing whose cross-sectional structure consisted of a single layer was previously used, but sheet packing has been developed to have excellent spring properties (elastic resilience), which is one of the main characteristics of sheet packing. For this reason, the following technique is used.
即ち表裏に多数のフック孔を開けた金属板（主として鉄

具体的には金属板の表裏には、表側から裏側へ向って開
けられた孔と、裏側から表側へ向って開けられた孔の多
数が交互に形成され、この金属板を中にして、その表裏
に耐熱材料を複合結合化したものである。That is, it is a sheet packing that is a composite of a metal plate (mainly an iron plate, depending on the application, a stainless steel plate or an aluminum plate) with many hook holes on the front and back sides, and a heat-resistant material. More specifically, on the front and back sides of the metal plate, a large number of holes are formed alternately from the front side to the back side and from the back side to the front side, and with this metal plate inside, Heat-resistant materials are compositely bonded on the front and back sides.
この場合、従来技術の１つは、耐熱材料として石綿やロ

を塗布し、次に加硫温度で加熱し、以って鉄板の表裏に
耐熱繊維材を複合結合化したシートパッキングである。In this case, one of the conventional techniques uses asbestos, rock wool, or a heat-resistant fiber material such as glass fiber as the heat-resistant material. That is, vulcanized synthetic rubber is melted using volatile oil, the melted synthetic rubber is mixed with these asbestos, etc., and then these are applied to the front and back of the metal plate having the hook holes, and then the vulcanization temperature is This sheet packing is made by heating the iron plate to form a composite bond of heat-resistant fiber material on the front and back sides of the iron plate.

、鉄板に関しては製作後の日時経過により錆びるので、
その周りに防錆剤が塗布されることが多い。The second method, which has been used recently, uses graphite particles as a heat-resistant material. In this case, conventionally, vulcanized synthetic rubber was melted using volatile oil, the melted synthetic rubber and graphite particles were mixed, and then 47 pieces of these were placed on the front and back sides of the metal plate having the hook holes. It is manufactured by heating at vulcanization temperature. By the way, among the metal plates mentioned above, iron plates rust due to the passage of time after manufacture, so
A rust inhibitor is often applied around it.

。The conventional technology described in L has been used for many years and is a useful technology. In particular, the hole wall of the hook hole has spring properties (elastic recovery properties) when the sheet packing is applied to the application area and tightened from the outside. However, while the applicant has been involved in the manufacture of sheet packing for a long time, he has discovered that there are several problems. In other words, when using an iron plate as the metal plate, although it is coated with a rust preventive agent, vulcanized synthetic rubber is used for bonding, and it is heated at vulcanization temperature when forming the composite. The rust preventive agent may deteriorate in quality, and since volatile oil (gasoline) is used as a solvent to dissolve synthetic rubber, the rust preventive agent may deteriorate due to its action. In the end, the iron plate rusted and lacked durability.
これは、上述した複合製品を得るに際して、種々の耐熱
材料を選ぶ為の研究を強く進めるも、その複合化の為の
手法が旧態依然であることによるものと考えられる。This is thought to be due to the fact that, although research has been strongly promoted to select various heat-resistant materials to obtain the above-mentioned composite products, the methods for making composites remain old-fashioned.

て特に０石綿等を用いる場合に、その耐熱温度が３００

た。Furthermore, in the case of technologies that use asbestos, rock wool, etc. as heat-resistant materials, there is a risk that these materials may enter human lungs during the manufacturing process, resulting in industrial accidents. Also, asbestos is used as a heat-resistant material.
Regardless of whether glass fiber or graphite particles are used, volatile oils such as triol solvents are used, so there is always a risk of fire during the manufacturing process, and there is a risk of harming the health of workers. Ta. In particular, when using 0 asbestos, etc., its heat resistance temperature is 300
The temperature was as low as about 400°C to 400°C, and its uses were limited.

An object of the present invention is to provide a sheet packing material having high heat resistance. In particular, (1) To provide a sheet packing that does not impair the elastic resilience of a metal plate, but rather enhances it, thereby making it possible to achieve the elastic resilience required for sheet packing.
総じて言えば■〜■の全てを同時に満たすことができる
シートパッキングを提供するにある。Overall, the purpose is to provide sheet packing that can simultaneously satisfy all of the above.
上記目的を達成する為に本発明は次の技術的手段を有す

化せしめて成ることを特徴とするシートパッキングであ
る。In order to achieve the above object, the present invention has the following technical means. That is, the present invention relates to a sheet packing in which a heat-resistant material is laminated and bonded to the front and back sides of a metal material in which a large number of holes having spring properties are formed passing through the front and back; This sheet packing is characterized by using powder particles obtained by mixing, mixing water-based rubber with the mixed powder particles, drying at room temperature and applying pressure, and laminating and bonding the metal material on the front and back sides.
上記に於いて用いることのできる金属材は、表裏に多数

こともできるし、網孔を有する金属網でもよい。又金属
板の場合、いわゆるフック孔と称して、表側から裏側に
向って突起状に形成された孔と、裏側から表側に向って
突起状に形成された孔が交互に存するものが望ましい。The metal material that can be used in the above case may be a metal plate (mainly iron plate, depending on the purpose, stainless steel plate, aluminum plate, etc.) with many holes formed on the front and back sides, or a metal plate with mesh holes. It can also be a net. In the case of a metal plate, it is preferable that so-called hook holes exist alternately with holes formed in a protruding shape from the front side toward the back side and holes formed in a protruding shape from the back side toward the front side.
且つこれらが鉄製の場合、それに防錆剤が塗布される。If these are made of iron, a rust preventive agent is applied to them.

で防錆剤の変質、劣化がなく、その機能が全く失われず
、防錆剤本来の機能を発揮する。故に、日時の経過に係
わらず錆の発生が著しく少なく、耐久性に富む。In this way, the mixed particles obtained by mixing graphite particles and catalpo powder are mixed with a small amount of water-based rubber and are laminated and bonded on a metal material by pressurizing and drying at room temperature. Since oil is not used and no special heating is required, the rust preventive does not change or deteriorate, and its functions are not lost at all, allowing the rust preventive to perform its original function. Therefore, the occurrence of rust is extremely low regardless of the passage of time, and it is highly durable.
同様に、積層材料として石綿やロックウールを用いてい
ないので、且つ揮撥油も用いていないので製造上、作業
員の健康を害することもなく、火災のおそれもなく安全
である。Similarly, since no asbestos or rock wool is used as the laminated material, and no volatile oil is used, the manufacturing process is safe, with no harm to the health of workers, and no risk of fire.
特に、黒鉛粒子とカタルポ粉末の混合粒子を用い、而も
常温で乾燥することによって上記材料の結合バインダー
として機能する為に用いる水性ラテックスの量も微量で
あるので、極めて高い温度、例えば６００°Ｃ程度に耐
えられるので適用場所に限定を受けない。In particular, since mixed particles of graphite particles and catalpo powder are used, and the amount of aqueous latex used to function as a binding binder for the above materials by drying at room temperature is small, the temperature is extremely high, e.g. 600°C. Since it can withstand certain conditions, there are no restrictions on where it can be applied.
次に添付図面に従い本発明の好適な実施例を詳述する。 Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
実施例１・・・第１図、第２図参照

及び裏面５側に各々積層結合化された黒鉛粒子とカタル
ポ粉末の混合粉粒子の層を示している。Example 1...See FIGS. 1 and 2. In the drawings, 1 indicates a metal material, and 2 and 3 represent graphite particles and catalpo powder laminated and bonded on the front surface 4 side and back surface 5 side of the metal material 1, respectively. shows a layer of mixed powder particles.

壁８，９がそれぞれ、締め付は時に於けるスプリング性
を発揮する。In this example, the metal material 1 has one hook hole 6 opened from the front 4 side toward the back 5 side, and the other hook hole 7 opened from the back 5 side toward the front 4 side, alternately. It shows a large number of iron plates formed. The hole walls 8 and 9 of each of the hook holes 6 and 7 exhibit spring properties when tightened, respectively.

、各フック孔６又は７の頂端１０，１１の孔隙は１．５
φ程度である。且つ鉄板自体の厚さは０゜１５〜２ｍｍ
程度のものが望まれる。The distance between the top ends 10 and 11 of the hook holes 6.7 in this iron plate is, for example, about 3 m. Therefore, the thickness t of the laminated and bonded sheet packing itself is about 311 Il, and each hook hole 6. The pore gap at the top ends 10 and 11 of 7 is 1.5
It is about φ. And the thickness of the iron plate itself is 0°15~2mm
A certain degree is desired.
勿論これらの寸法設定は、このシートパッキングが適用
される条件に応じて種々変えることができる。Of course, these dimensional settings can be varied depending on the conditions to which this sheet packing is applied.

の２つがある。When these mixed powder particles are laminated and bonded to the metal plate 1, a conventional method is used in which they are dissolved with volatile oil, mixed with synthetic rubber, and heated at a vulcanization temperature. I don't take it at all. That is, the weight ratio of the metal plate 1 is 5
In the case of approximately 0 parts by weight, 13 parts by weight of graphite particles and approximately 25 parts by weight of catarupo powder were mixed, and then 1 part by weight was added.
Add a small amount of water-based rubber of about 2 weight, mix well, and apply this to the front 4 side and back 5 side of the metal plate 1 using a coating roll or the like. During coating, roll coating pressure is applied, and under this pressure, these mixed powder particles are laminated and bonded to the front side 4 and back side 5 of the metal plate 1 under the action of the water-based rubber 7. In other words, water-based rubber dries at room temperature,
These materials are composited. The role of the aqueous rubber itself as a binder is to bind the mixed powder particles to each other, and to bind the layers of these mixed powder particles to each surface of the front 4 and back 5.
このように表４及び裏５に均一に塗布すると、金属板１

するものである。When coated uniformly on the front 4 and back 5 in this way, the metal plate 1
Layers 2 and 3 of mixed powder particles of graphite particles and catalpo powder are uniformly formed on the upper and lower sides of the inner layer, and a sheet packing which is a flat laminated composite product is obtained as a whole. This is then cut into a desired shape depending on the conditions of the intended use.

知の防錆剤が塗布されるものである。Since the layers 2 and 3 of the mixed powder particles penetrate into the respective holes of the hook holes 6 and 7 and are combined, the layers 2 and 3 of the mixed powder particles are more firmly laminated on the metal plate 1. Further, although iron plates are mainly used as the metal material, stainless steel, aluminum plates, or other alloys thereof may be used in some cases. In the case of the above-mentioned iron plate, a known rust preventive agent is applied to the circumferential surface thereof.
