| titleOfInvention | Wear-resistant sealing ring and preparation method thereof |
| abstract | The application relates to the field of sealing rings, and particularly discloses a wear-resistant sealing ring and a preparation method thereof. The wear-resistant sealing ring comprises a sealing ring body, and the sealing ring body comprises the following raw materials: polytetrafluoroethylene suspended particles, potassium titanate whiskers, glass fibers, PEEK, rosin resin-alcohol ether phosphate ester compound and molybdenum disulfide; the preparation method comprises the following steps: s1, mixing raw materials; and S2, die pressing and sintering. The polytetrafluoroethylene suspended particles and the rosin resin-alcohol ether phosphate ester compound are adopted, the polytetrafluoroethylene suspended particles have better dispersibility and can be mixed with raw materials more uniformly, the rosin resin-alcohol ether phosphate ester compound is adhered to the surface of the polytetrafluoroethylene suspended particles, the binding force between the raw materials is improved after mixing, the compatibility of PEEK and the polytetrafluoroethylene suspended particles is favorably improved, the wear resistance of the sealing ring body is improved, the sealing ring body is more durable, the material waste caused by the premature damage of the sealing ring body is reduced, and a certain energy-saving effect is achieved. |
