（4）, by step（3）The clay handled well handles 1-2h at 430-435 DEG C under anaerobic, then heats to 800-
820 DEG C continue with 30-35min, are then crushed clay, sieve with 100 mesh sieve, and obtain modified clay.
2. a kind of production method of explosion-proof foamed aluminium board described in claim 1, which is characterized in that include the following steps：
（1）, by fiberglass braided networking, be put into mold；
（2）, mold is placed under nitrogen protection, phenolic resin, aluminium powder, auxiliary agent are ground and are uniformly mixed respectively, is then existed
At 285-290 DEG C then isothermal holding 2h, natural cooling are uniformly mixed with foaming agent；
（3）, by step（2）The raw material handled well is added in mold, and isothermal holding 1h, is then cooled at 730-740 DEG C
700-702 DEG C, to applying the pressure of 6-8MPa in mold, pressurize handles 2min, natural cooling, and die sinking obtains explosion-proof foamed aluminium
Plate.
