ール作用が不完全になる点があつた。 When conventional machines use rubber gaskets for joints that are simply tightened, attempting to remove the gaskets during disassembly often causes them to tear or damage, making them unusable. There was a packing type in which 1a was surrounded by plastic material 2. Also, a circular rubber gasket 1b is attached to the screw-in type cap part as shown in Fig. 2.
When using cap 3 and rubber gasket 1b
Since the contact resistance with the rubber seal 1 is large, when screwing the cap 3 onto the body 4 and tightening it,
There were many cases in which wrinkles or displacement occurred on b, resulting in incomplete sealing action.

Figures 6 to 10 show experimental examples of the relationship between the vulcanized adhesive strength and the second packing of SB.
The results of using NR instead of R were also omitted as there was no significant difference. Figure 6 shows the vulcanization adhesion temperature, and the strength on the vertical axis is the highest strength in this experiment.
% (the same applies to Figures 7 to 9), and the optimum conditions were 130 as a result of vulcanization bonding time of 30 minutes, same pressure of 100 kg/cm 2 , adhesive application amount of 100 g/m 2

As a result of conducting at m2 , the optimum conditions are 20 to 30 minutes, practical area
It shows more than 10 minutes. Figure 8 shows the vulcanization adhesive pressure, vulcanization adhesive temperature 140℃, same time 20 minutes,
The results of the experiment using an adhesive coating amount of 100 g/m 2 showed that the optimum condition was 100 Kg/cm 2 or more, and the practical range was 60 Kg/cm 2 or more. Figure 9 shows the amount of adhesive applied, which was applied by spraying or brushing, at a vulcanization temperature of 140°C, a time of 20 minutes, a pressure of 100 kg/cm 2 and an adhesive rubber content of 20 to 30% by weight. As a result of the implementation, the optimal conditions were 100
~150g/ m2 , practical range 70~220g/ m2 . Figure 10 shows the amount of Desmodule R added to the adhesive.
As a result, the optimum condition was 2 to 6% by weight, the practical range was 2 to 10% by weight, and above 10% by weight , the adhesive became viscous. It became so large that it could not be used as an adhesive because the rubber adhesive hardened quickly.

構造により両者の長所を発揮することができる。 As explained in detail above, according to the present invention, compared to a rubber gasket that uses only elasticity, it is possible to create a structure in which rubber and plastic are strongly bonded together, so that the elasticity of rubber and the toughness of plastic can be combined.
In addition, the small coefficient of friction etc. In the case of the conventional packing shown in Fig. 1, which is simply tightened and used at the joints of machines, etc., the circumference is surrounded by plastic, which requires man-hours such as molding the plastic, increases manufacturing costs, and increases the thickness. However, the seal packing manufactured by the manufacturing method of this invention has a structure as shown in Fig. 3, is low in cost, and can be vulcanized even if the hardness of the rubber changes. Since it only requires gluing, it can be made thin and has good sealing properties. Further, when used in a screw-in type cap as shown in Fig. 5, the soft rubber material 1c is compressed while the contact portion 8 between the plastic surface and the cap surface slides, so that the seal will not wrinkle or shift. . When used for other purposes than packing, the structure in which rubber and plastic are bonded and integrated allows the advantages of both to be exhibited.
