Description

Inorganic fireproof expansion sealing element Technical Field The utility model relates to the technical field of sealing elements, in particular to an inorganic fireproof expansion sealing element. Background The existing fireproof expansion sealing parts in the market mainly adopt the combination of expandable graphite and organic solvent, for example, the A-class fireproof expansion sealing parts adopt the method of scraping vinyl acetate-vinyl copolymer emulsion on leather to mix the expandable graphite and inorganic filler mixture, and the fireproof expansion sealing parts with good flexibility are produced by plate making, airing and stripping. For fire-proof expansion sealing elements which are filled in the cavity and do not need flexibility, how to replace expensive organic solvents is the key of technical research. Disclosure of utility model The utility model aims to provide an inorganic fireproof expansion sealing member which has the advantages of high strength, no corrosion and no volatilization, reduces the cost on the basis of ensuring the fireproof expansion performance, reduces the recovery and treatment of waste materials, and improves the fireproof heat insulation performance. In order to achieve the above purpose, the utility model provides an inorganic fireproof expansion sealing component, which comprises an expansion body carrier and an expansion body material layer, wherein the expansion body material layer is arranged on the outer surface of the expansion body carrier or around the expansion body carrier, and the expansion body carrier is an inorganic plate. Preferably, the inorganic board is a glass magnesium fireproof board or a perlite fireproof board. Preferably, the expansion body material layer is a high-power expansion body material layer or a reinforced inorganic expansion body material layer. Preferably, the expansion body carrier used for filling the fireproof door leaf is a perlite fireproof plate, and the seam between two adjacent perlite fireproof plates is filled with the expansion body material layer. Preferably, the expansion body carrier for the bridge-cut-off aluminum fireproof window frame is a glass magnesium fireproof plate, the glass magnesium fireproof plate and the expansion body material layer are filled in a cavity of the bridge-cut-off aluminum fireproof window frame, and the expansion body material layer is arranged on the upper surface of the glass magnesium fireproof plate. Preferably, the expansion body carrier for the steel fireproof door frame is a glass magnesium fireproof plate, the glass magnesium fireproof plate and the expansion body material layer are filled in a door frame cavity of the steel fireproof door frame, and the expansion body material layer is arranged on the upper surface of the glass magnesium fireproof plate. Therefore, the inorganic fireproof expansion sealing member adopting the structure has the advantages of high strength, no corrosion and no volatilization, reduces the cost on the basis of ensuring the fireproof expansion performance, reduces the recovery and treatment of waste materials, and improves the fireproof heat insulation performance.
