Abstract

There is provided a new technique of making easy to use a rubber member formed by using a rubber composition containing rubber and porous carbon material particles produced from plant material, wherein a laminated body includes a supporting member; and a porous carbon material particle-containing rubber layer formed by a rubber composition containing rubber and porous carbon material particles produced from plant material, and further includes an intermediate rubber layer between the supporting member and the porous carbon material particle-containing rubber layer; wherein the supporting member is vulcanization-adhered to the intermediate rubber layer, and the intermediate rubber layer is vulcanization-adhered to the porous carbon material particle-containing rubber layer, to thereby vulcanization-adhere the porous carbon material particle-containing rubber layer on the supporting member.

First claim

What is claimed is:

1 . A laminated body, comprising:
a supporting member; a porous carbon material particle-containing rubber layer which is vulcanization-adhered on the supporting member and made of a rubber composition containing rubber and porous carbon material particles produced from plant material; and further an intermediate rubber layer made of a rubber material, between the supporting member and the porous carbon material particle-containing rubber layer, wherein the supporting member is vulcanization-adhered to the intermediate rubber layer, and the intermediate rubber layer is vulcanization-adhered to the porous carbon material particle-containing rubber layer, to thereby vulcanization-adhere the porous carbon material particle-containing rubber layer on the supporting member.

2 . The laminated body according to claim 1 , wherein a content of the porous carbon material particles in the rubber composition, is 160 parts by mass or more based on 100 parts by mass of the rubber contained in the rubber composition.

3 . The laminated body according to claim 1 , wherein the supporting member is made of a material having a higher rigidity than the rubber composition constituting the porous carbon material particle-containing rubber layer.

4 . The laminated body according to claim 1 , wherein a thickness of the intermediate rubber layer is larger than a thickness of the porous carbon material particle-containing rubber layer.

5 . The laminated body according to claim 1 , wherein the rubber contained in the rubber composition, and rubber contained in the rubber material are same kind of materials.

6 . The laminated body according to claim 1 , wherein the rubber contained in the rubber composition, and rubber contained in the rubber material, are the materials that can be vulcanized under the same vulcanization condition.
