Problems solved by technology

[0003] However, when the existing sealing materials are in contact with parts with high rotating speeds, they are severely worn and their service life is greatly reduced, which seriously affects their sealing effect and brings huge safety hazards to production. Therefore, there is an urgent need for a wear-resistant sealing material to meet The need for long-term sealing at high rotational speeds

Description

technical field [0001] The invention belongs to the field of sealing materials, and relates to a wear-resistant sealing material and a preparation method thereof. Background technique [0002] Sealing materials refer to materials that can withstand joint displacement to achieve airtightness and watertightness and are embedded in building joints. Early sealing materials are mainly fabrics, mineral fibers or felts. With the development of industrial technology, in order to meet the increasingly complex and diverse requirements of hydraulic and pneumatic seals, sealing materials have also developed rapidly, with more and more types and continuous improvement of physical and chemical properties; [0003] However, when the existing sealing materials are in contact with parts with high rotating speeds, they are severely worn and their service life is greatly reduced, which seriously affects their sealing effect and brings huge safety hazards to production. Therefore, there is an u...
