The present invention provides an explosion-proof material and use, and a method for preparing the explosion-proof material is as follows: 22-28 parts by weight of short cut carbon fiber with the length of 10-15mm, 70-75 parts by weight of ceramic and 1.5-2.5 parts by weight of rare earth are evenly stirred in proportion, the raw materials are added into a mold, the mold is put into a pressure vessel, the pressure vessel is then heated to 300 DEG C and pressurized to 15 kg for ladder-type high temperature and high pressure qualitative manufacturing and compaction, 150 DEG C is increased in each step of ladder-type temperature increase, and 15 kg pressure is increased, and each step stays for 5 minutes, when the temperature reaches 1650 DEG C, the temperature holds for 25 minutes, and the mold is taken out after reduction of the pressure, exhausting, cutting-off of power and cooling to room temperature. The explosion-proof material can be used as the explosion-proof clothing outer layer material, lining can be synthesized from a rubber foam material and cloth, and is contacted with the body, and the main purpose is cushion of impact injuries of high pressure and a greater impact on the body.
