However, in the above-mentioned prior art, a step of first pressurizing and heating an unvulcanized EPT sheet in order to manufacture a vulcanized EPT sheet by itself, for example, is carried out. Since two pressure heating steps, that is, a step in which a sulphated EPT sheet and an uncured phenolic resin are superposed on each other are put in a press again and heated under pressure, heat loss is extremely high. There is a big problem. In addition, there is a problem that the work cost becomes high and the product cost becomes high because the work is very troublesome.

According to the first aspect of the present invention, a work piece is first formed in which unvulcanized rubber and uncured phenol resin are superposed. Then, under the first pressurizing and heating condition in the press machine, the unvulcanized rubber of the workpiece is vulcanized, whereby a laminated plate of the vulcanized rubber and the uncured phenol resin is formed. . Then, by setting the pressure heating condition in the same press machine to the second pressure heating condition, the uncured phenol resin is cured to form the cured phenol resin, and the cured phenol resin is fused to the rubber. As a result, a laminated plate of vulcanized rubber and phenol resin is formed. That is, a mixture of unvulcanized rubber and uncured phenolic resin is heated under pressure only once, and at that time, the pressure heating condition is divided into two stages of first and second pressure heating conditions. Thus, after vulcanizing the unvulcanized rubber, the uncured phenol resin is cured and a laminated plate of both is formed.

The second pressure-heating condition is higher in pressure and temperature than the first pressure-heating condition, but the rubber is at least in the second pressure-heating condition according to the first pressure-heating condition. Since the rubber is vulcanized until it can withstand, the rubber does not melt and flow even if it is pressurized and heated under the second pressure and heating condition. On the contrary, the rubber is further vulcanized under the second pressurizing and heating condition.

Here, as described above, the curing conditions [P 2 and H 2 ] of the uncured phenolic resin 2 are as follows.
The pressure and temperature are higher than the vulcanization conditions [P 1 and H 1 ] of the sheet 1. Therefore, for example, when the workpiece 3 is heated under pressure only under the curing conditions [P 2 and H 2 ] of the uncured phenolic resin 2, the unvulcanized EPT sheet 1 becomes the above curing conditions [P 2 and H 2].
2 ), and it will melt and flow out, and it will not be possible to maintain a predetermined thickness. However, according to the present embodiment, the vulcanization condition [P 2 and H 2 ] of the unvulcanized EPT sheet 1 before the heating under pressure [P 2 and H 2 ] is performed.
1 and H 1 ], the workpiece 3 is pressurized and heated to form an (vulcanized) EPT sheet. Due to this vulcanization, the pressure resistance and heat resistance of the EPT sheet are unvulcanized EP.
Since it is much higher than that of the T sheet 1, even if the EPT sheet is pressurized and heated under the above curing conditions [P 2 and H 2 ], the EPT sheet does not flow out. Therefore,
The (vulcanized) EPT sheet can be maintained at a predetermined thickness.

In step S1, the unvulcanized EPT sheet 1 and the uncured phenolic resin 2 are not simply superposed on each other, but both (specifically, the unvulcanized EPT sheet 1 and the uncured phenolic resin 2 are By pressing one of the kraft papers stacked to form the non-vulcanized EPT sheet 1 side), the two are firmly adhered to each other, that is, pressed in an integrated state. Heating may be performed. That is, unvulcanized EPT
Since the sheet 1 (uncured rubber) is a very soft substance, it is very difficult to handle as it is, but when it is integrated with the uncured phenol resin 2 by the above-mentioned topping, the unvulcanized sheet is unvulcanized. The difficulty of handling the EPT sheet 1 can be eliminated, and the pressure heating can be facilitated.

Further, in step S3, the workpiece 3 is pressurized and heated for a time t 1 under the vulcanization conditions [P 1 and H 1 ] of the unvulcanized EPT sheet 1 (vulcanized) EPT. Although a sheet was formed, it is not necessary here to completely vulcanize the unvulcanized EPT sheet 1.

Before pressurizing and heating under the above-mentioned pressurizing and heating conditions, the workpiece is pressurized and heated under the first pressurizing and heating conditions so that the unvulcanized rubber can withstand at least the above-mentioned second pressurizing and heating conditions. It is vulcanized until it is ready for use. Therefore, even if the rubber is pressurized and heated under the second pressure and heating condition, the rubber does not flow out, and the rubber can be maintained at a predetermined thickness.
