In high-speed mixer, mixing speed 600r/min, mixing time 40min, then thereto be added hydroxyethyl ether cellulose, go from
Sub- water to raw material is sufficiently mixed, mixing speed 800r/min, and mixing time 50min obtains mixture A；
Paper pulp, ammonium octamolybdate, silicon carbide, micro powder graphite are sent into mold and mask paper are made, then mixture is poured on by step 3
It is pressed in mask paper matrix tool, until slurry final set is to get of the invention based on modified BPO fiber Thistle board.
