Abstract
The present invention discloses an alumina ceramic composite lining board and a preparation method thereof. The weight percentage content of alumina ceramic powder is 75-85%, the weight percentage content of acetone is 2-4%, the weight percentage content of micro glass beads is 1.5-3.5%, the weight percentage content of triethylene dimethyl silane is 0.5-2.5%, the weight percentage content of titanate is 4-6%, and the weight percentage content of quartzite is 5-10%. The sum of the materials is 100%, and the materials are evenly mixed and stirred and are pressed in a cold mode by using a mould to make the materials densify and form. After the materials are heated for 8-12 hours under temperature of 380 DEG and 420 DEG and are pressed for 0.5-2 hours in a heating mode under pressure of 18-22MPa, the materials are cooled to normal temperature and are made into the alumina ceramic composite lining board. The lining board has the characteristics of high temperature resistance, antioxidation, high wear resistance, flame retardant resistance, lowest friction coefficient, high relative strength and toughness, etc., and is suitable for the industrial fields of machinery, alloy, chemical industry, etc.
