Description

technical field [0001] The invention belongs to the field of sealing materials, and relates to a high-temperature-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, the service life of the existing sealing materials is greatly reduced when the ambient temperature is high, but when the temperature is high, the volume of the sealing material will expand, seriously affecting its sealing effect, and bringing huge safety haz...
