However, it is necessary to prevent the rubber packing from falling to improve workability when the installation location is facing downwards such as the bottom of an automobile chassis or ceiling, or when facing sideways such as a wall. Conventionally, the surface of the rubber packing is activated by treating it with a solvent such as MEK or toluene, or a halogen-based chemical or acid, and a piece of double-sided adhesive tape is attached to this activated surface. Was temporarily fixed to the lower surface of the chassis or the like by pressure bonding.

Made from sulfur. After vulcanization, the surface is subjected to corona discharge treatment. The conditions for this corona discharge treatment are preferably a gap of 1 to 6 mm between the treatment roll of the treatment machine and the rubber sheet, a discharge voltage of 25 to 50 KV, and a treatment speed of 1 to 5 m / min.

はなく、機械部品の取付けが容易になる。By applying the corona discharge treatment to the surface of the rubber sheet, the treated surface is activated and the wetting property is improved. Therefore, a rubber packing having good adhesiveness to the double-sided adhesive tape can be obtained, the double-sided adhesive tape is attached to the discharge-treated surface of the rubber packing, and the attachment surface of the adhesive tape is pressure-bonded to a part for mounting a machine base or the like, The rubber packing is easily temporarily fixed, does not fall off by its own weight, and the mechanical parts can be easily attached.

Exceeding 6mm, discharge voltage is 2
If it is less than 5 KV, the treatment is insufficient and the desired adhesive strength cannot be obtained. Further, if the processing speed is less than 1 m / min, the treated surface of the rubber sheet is easily broken,
On the other hand, if it exceeds 5 m / min, the desired adhesive force cannot be obtained.
