Abstract:
A new kind of alumina fiber-based expandable insulation material was designed using expandable graphite, alumina fiber and aluminum phosphate adhesives, and fabricated through wet mixing, vacuum suction filter, pressure drying. This material had 100%-300% of volume expansion ratio under temperatures from 400 to 1000°C, well heat insulation performance and mechanical property after expansion. Due to the special expanding property of expandable graphite, the heating mode will seriously impact on the properties of material. In this paper, the influence of two different heating-up modes on the material properties had been studied. At slowly heating-up mode, the expansion ratio almost maintained at 115%, and the compression strength increased visibly comparing with fast heating-up. At one-side heating-up mode, the expansion ratio was lower than the all-side heating-up mode, which respectively were 164.9 % and 226.9% at 800°C, and the compression strength increased slightly because of the extension of heat treatment time.
