For example, Class A fire-resistant expandable seals are produced by coating leather with a mixture of vinyl acetate-elixir copolymer emulsion, expandable graphite, and inorganic fillers, followed by slab preparation, drying, and slitting to produce flexible fire-resistant expandable seals. For fire-resistant expandable seals that require cavity filling and do not demand flexibility, finding a replacement for expensive organic solvents is a key area of ​​technological research.

[0019] Figure 1 This is a structural diagram of an inorganic fireproof expansion sealant with perlite fireproof board as the expansion carrier. Figure 2The figure shows a schematic diagram of an inorganic fire-resistant expansion seal with a magnesium oxide fireproof board as the expansion carrier. This invention provides an inorganic fire-resistant expansion seal, including an expansion carrier 1 and an expansion material layer 2. The expansion material layer 2 is disposed on the outer surface of the expansion carrier 1 or around the expansion carrier 1. The expansion carrier 1 is an inorganic board. The inorganic board is either a magnesium oxide fireproof board or a perlite fireproof board. The inherent fire-resistant and heat-insulating properties of the inorganic board improve the fire-resistant and heat-insulating performance of the inorganic fire-resistant expansion seal, enhancing its original expansion sealing performance. The carrier itself occupies less space in the cavity, reducing the need for an expansion body. The expansion material layer 2 is a high-expansion expansion material layer or a reinforced inorganic expansion material layer. The high-expansion expansion material layer is composed of a sodium silicate aqueous solution and expandable graphite, with the sodium silicate aqueous solution serving as the solvent carrier for the expandable graphite. The mass ratio of the two is 2:1. The reinforced inorganic expandable material layer is composed of sodium silicate aqueous solution, clay, and expandable graphite in a mass ratio of 7:2:2. The sodium silicate aqueous solution solidifies in air primarily through two processes: carbonization and dehydration crystallization, forming a solidified material that is externally hard and waterproof while containing internal water of crystallization, thus possessing both waterproof and water-retaining functions. When the solidified inorganic expandable material layer encounters high temperatures, the solid sodium silicate hydrolyzes and expands, and the evenly dispersed expandable graphite expands upon heating, fully filling the remaining space. This forms a composite thermal insulation material consisting of a graphite expandable body and an inorganic thermal insulation board, providing both fire resistance and thermal insulation. Furthermore, the reinforced inorganic expandable material incorporates inorganic fillers within the expandable body. The curing hardness of the inorganic fillers reduces the expansion of sodium silicate at high temperatures, and the expandable graphite slightly expands at the solidification sites, improving the fire resistance integrity and overall strength of the inorganic board after fire exposure, preventing pulverization and collapse.

The magnesium oxide fireproof board 22 and the expansion material layer 2 are filled in the cavity of the thermally broken aluminum fireproof window frame 21. The expansion material layer 2 is disposed on the upper surface of the magnesium oxide fireproof board 22.
