SOFC HIGH-TEMPERATURE VERMICULITE SEALING MATERIAL AND PREPARATION METHOD THEREFOR

Resumen de: EP4790036A1

The present invention relates to the technical field of sealing materials, and discloses a high-temperature vermiculite sealing material for SOFC, and a preparation method thereof. The material is prepared from modified chemically expanded vermiculite and negative-ion high-temperature expanded vermiculite. The modified chemically expanded vermiculite carries positive charges, and the negative-ion high-temperature expanded vermiculite carries negative charges. After the modified chemically expanded vermiculite and the negative-ion high-temperature expanded vermiculite are mixed, electrostatic attraction is generated to achieve combination. The material does not use binders, so that the loss on ignition is significantly reduced without changing the combined strength of the sealing material. The stearate serves as an intercalation agent of chemically expanded vermiculite. The modified chemically expanded vermiculite prepared from the stearate has high-temperature resistant compressive strength at 700°C. The negative-ion high-temperature expanded vermiculite is formed by using negative ion air to treat high-temperature expanded vermiculite to enable the high-temperature expanded vermiculite to load and accumulate negative charges. Using the negative ion air to treat the high-temperature expanded vermiculite does not require the use of chemical agents, the process is simple, and large-scale production can be achieved.
