Abstract

To provide a double-belt press apparatus capable of stably forming flexible metal foil laminates witli an excellent external appearance even after extended continuous manufacturing. In the present inbention, the double-belt press apparatus mounts the endless belts, wherein endless belts whose 0.2% proof stress under a 300 DEG C condition is 1100N/mm<SP>2</SP> or more. These things prevent flaws inside the endless belts from transferring to products, because these things increase endurance of endless belts and can effectively prevent impairment in surface flatness and smoothness of products. Therefore, laminates with an excellent external appearance can be continuously and stably manufactured for an extended period of time.

The laminated body is made of an aromatic polyimide film and a y-adhesive (epoxy resin, etc.), and is heat-resistant and dimensionally stable. The double-pressing device is used to gather the heat-pressing aromatic surface. ^ =: 卩 _Miscellaneous fine coffee ㈣ Secret heating line up and down ======== A stack of "layer f" device. The thermocompression device is divided into the use of hydraulic plate type ") or the drum that completely makes the endless belt rotate And / or rolling methods such as roller crimping arranged between the drums. As shown in the example of Fig. 4, the "liquid stationed double pressure belt device" means that a plurality of thin materials 21 to 26 are continuously sent to the direction of the arrow X using the drum of the drum indicated by the symbol D. The next pair of endless belts 1 And 1, use the liquid arranged in the 1 m area 11 of each endless belt. 3 The thin plates 21 ~ 23, 24 ~ 26 are connected to each other through the endless belt to form a laminated body 27, 28 n, such as a body. 'The metal "1:23, 24, 26) and the thermocompression-bondable multilayer polyimide film (22, 25) supplied as the sheet material for the device are manufactured by osmotic crimping 5 200534938 (27, 28). The products 27 and 28 were each produced as a three-layer laminate of metal foil / polyimide film / metal foil. Fig. 5 is a schematic diagram of the hydraulic surface 31 of the hydraulic plate 3 shown in Fig. 4. The hydraulic pressure of the hydraulic plate 3 The surface 31 is a surface facing the inner side surface 12 of the endless belt 1 (see FIG. 4). As shown in FIG. 5, a groove 33 is provided on the hydraulic surface 31 of the hydraulic plate 3 along the periphery 32 of the hydraulic surface 31. Install the hydraulic closed frame 4. In addition, the arrow x indicates the direction of travel of the thermocompression plate material. Σ FIG. 6 is a schematic cross-sectional view showing a portion A in FIG. 4. As shown in FIG. 6, the endless belt 1 of the upper T travels in the direction of the arrow X, and the hydraulic pressure p is used in the area where the slab material 2 and the hydraulic plate 3 are opposite to each other. 33. Secret Chi 4 and facing Lili plate 3. The hydraulic surface 3 of the liquid plate 3 is used to close the hydraulic medium 5 Λ 1 and the endless belt 1 is used to close the hydraulic medium 5. However, in manufacturing; ίΠί, the belt 1 uses liquid The sheet material 2 is pressurized by the shooting. The medium is heated, and presses the same upwards through the endless belt 1. However, the rolling type double pressure belt device is a typical example. The drums arranged between the rotating and arranged drums form the most compact body. [The wheel group 'is heated and pressurized through an endless belt, and is connected by pressure. I Wenhai drums or rollers are mainly induction heating.'

Continuous production, the surface of the product has been smoothed. Therefore, the Department of Defense Xijing ί 明, the main purpose is to provide-a kind of double ㈣ device and the use of Χ 生 原 Ξ 体 the method of ingenuity 'detailed review of the damaged surface smoothness "Report = the last one improved the double pressure belt device, long-term continuous manufacturing, and can also form a flexible metal foil laminate with good outer diameter.

The problem of solving the problem <iUft's review of the above-mentioned surface smoothness impaired part occurred originally on the drum arranged in the closed area of the endless belt, and in the hydraulic pressure llfn II, the inner side of the endless belt was scratched. U-shaped deformation occurs on the outer side (the endless T-side) and is transferred to the product. Pulling Ϊ 二 i: Study the conclusion that the endurance of the temperature condition of ^ and 时 is more than a fixed value when the endless belt that is difficult to occur such a fine deformation can be prevented. In addition, in the present invention, "damages the surface smoothness": that is, the surface of her body is formed with recesses or protrusions. Regardless of the specific shape, the body has newly discovered a value of 30 ° under the rc condition. 2% endurance system 1ιοον / "The i-end belt is difficult to deform even when the double pressure belt device is continuously operated for a long time. This description is completed in accordance with this new knowledge. That is, 'the present invention provides-a double loop device, first of all The multi-sheet material is continuously inserted into an endless belt configured as an upper-lower-opposite belt, and a thermal compression bonding device disposed in the it domain of the endless belt is used to thermally produce the laminate through the endless belt.

The benefits of 0.2% endurance at 10000 N / mm2 or higher under the condition of 300 c. From the book μ For example, a stainless steel belt of precipitation hardening type can be used. Τ This: precipitation hardening type "Stainless steel" is one or two or more kinds of A1, Ti, Nb, Cu, etc., and then heat-treated to increase the strength. The heat treatment is performed at a temperature at which the first-class region becomes a supersaturated state. After the treatment, the temperature is low and medium. Intermetallic compounds are precipitated to increase the strength of stainless steel. This U f -type stainless steel is classified into martensitic system, ferrite system, and Wu system based on the composition of the substrate. In addition, at 300 ° C · 2% endurance is ll00N / W = good, so that it contains at least titanium. The lamp contains at least a hardened type. In addition, in the present invention, a flexible metal foil laminate means an aromatic 3 = a film laminate, and an aromatic polyimide-based film is suitable for hot pressing.
