High-density ceramic fiber board not prone to secondary cracking and preparation method thereof
The invention provides a high-density ceramic fiber board not prone to secondary cracking. The high-density ceramic fiber board is prepared from, by mass, 15-40wt% of inorganic composite fibers, 0.5-5wt% of organic fibers, 0.5-2wt% of glass fiber chopped strands, 40-55% of refractory filler, 4-10wt% of cationic organic binding agents and 8%-13% of anionic inorganic binding agents. The inorganic composite fibers comprise ceramic fiber thread throwing cotton, ceramic fiber blowing cotton and soluble fiber cotton. The minimum density of the high-density ceramic fiber board is 765Kg/m < 3 >, the maximum density of the high-density ceramic fiber board is 1300Kg/m < 3 >, the minimum compressive strength of the high-density ceramic fiber board is 2.5 MPa, the maximum compressive strength of the high-density ceramic fiber board is 15MPa, and the use temperature of the high-density ceramic fiber board can reach 1100 DEG C. The invention further provides a preparation method of the high-density ceramic fiber board not prone to secondary cracking.
