Corrosion-resistant magnesium-aluminum fire resistant material and preparation method therefor
The invention relates to a corrosion-resistant magnesium-aluminum fire resistant material and a preparation method therefor. The corrosion-resistant magnesium-aluminum fire resistant material is prepared by adding an auxiliary additive, nano magnesium oxide, zirconium oxide, a binding agent and nano aluminum oxide while taking magnesium aluminate spinel in different grain sizes. The product provided by the invention has a more uniform texture structure, so that the strength and the thermal shock resistance of the product are improved; the particle size of nano zinc oxide is small, so that fine pores can be filled, and therefore, the porosity of the product is reduced and the volume density is improved; the material is high in fire-resisting degree, excellent in corrosion resistance, good in thermal shock resistance and wide in sintering temperature range.
