| titleOfInvention | Manufacturing method of decomposable rubber component for drilling tool |
| abstract | The present invention is a decomposable rubber member for drilling tools; a decomposable sealing member or protective member for drilling tools composed of the member; With respect to 100 parts by mass of decomposable rubber, it is formed from a rubber material (may contain other rubber materials and/or reinforcing materials) containing 0.1 to 20 parts by mass of a decomposable accelerator, preferably the mass after immersion in water at 150°C for 24 hours or 50% strain The reduction rate of compressive stress is 5% or more, and/or the reduction rate of mass after immersion in water at 150°C for 72 hours is 5 to 100%, and the tensile fracture strain at 66°C is 50% if desired. Above, the 70% strain compressive stress is 10 MPa or more and the compressive fracture strain is 50% or more. |
