（産業上の利用分野）
本発明は基布付シリコーンゴムスポンジの製造方法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing a silicone rubber sponge with a base fabric.
（従来の技術）
シリコーンゴムスポンジを被接着物に接着させる場合、
シリコーン自体が難接着性を有するため、ＲＴＶシリコ
ーンを接着剤に用いることが従来行われている。(Prior art) When adhering a silicone rubber sponge to an object,
Since silicone itself has poor adhesion, RTV silicone has conventionally been used as an adhesive.

ある。(Problems to be Solved by the Invention) However, in the conventional method described above, the curing time of RTV silicone is at least 24 hours, so the time required for adhesion is extremely long, and products with silicone rubber sponge bonded cannot be manufactured. There is a problem that it becomes a factor of cost increase when doing so.

でき、コストダウンを図ることができる。In addition, the silicone rubber sponge vulcanized and bonded to the base fabric can be obtained at the same time as the silicone rubber sponge is vulcanized, and the time required for vulcanization is shorter than that of the silicone rubber sponge material and the vulcanized silicone rubber. Hot air vulcanization is applied to the silicone rubber material that adheres the sponge to the base fabric.
Alternatively, since organic peroxides that can be press vulcanized are kneaded, these rubber materials can be molded by hot air vulcanization or press vulcanization for a short time (5 minutes to 3 minutes under conditions of 120° to 18060°C).
As a result, it is possible to significantly shorten the manufacturing time of products to which silicone rubber sponge is bonded, and to reduce costs.
