| titleOfInvention | A kind of high-speed die steel drill bit and preparation method thereof |
| abstract | A high-speed die steel drill bit and a preparation method thereof, the high-speed die steel drill bit comprises the following components in parts by weight: 40-60 parts of steel; 20-30 parts of tin oxide; 20-30 parts of cobalt oxide; 20 parts of chromium oxide ～30 parts; 10-15 parts of modified imidazole-castor seed oil micro-nano capsule particles; 8-12 parts of polymer initiator; 3-5 parts of vulcanization accelerator; 3-5 parts of flame retardant. The application provides a high-speed die steel drill bit and a preparation method thereof. The steel drill bit has excellent characteristics of high temperature resistance and acid resistance, thereby prolonging the service life of the drill bit. |
