Ceramic fiber sealing gasket and preparation method thereof
The invention provides a ceramic fiber sealing gasket. The ceramic fiber sealing gasket is prepared from the following raw materials in parts by weight: 20-48 parts of blowing aluminum silicate fiber, 50-75 parts of swinging aluminum silicate fiber and 2-10 parts of an organic binding agent. Due to the combination of the swinging aluminum silicate fiber with the blowing aluminum silicate fiber, the product has good elasticity, compressibility and volume density. In addition, due to the interaction of the added organic binding agent with the swinging aluminum silicate fiber and the blowing aluminum silicate fiber, the elasticity, compressibility and volume density of the ceramic fiber sealing gasket are improved further. Experimental results show that the compressibility of the ceramic fiber sealing gasket in the thickness direction is equal to or less than 29% under the pressure of 8.82KPa, the compressibility of the ceramic fiber sealing gasket in the thickness direction is equal to or more than 54% under the pressure of 91.1KPa, and the permeability resistance of the ceramic fiber sealing gasket is 0.1-1.0MPa.
