NOVELTY - Explosion-proof material comprises 30-40 wt.% titanium-copper alloy and 60-70 wt.% graphene; where the titanium-copper alloy including 60-65 wt.% titanium, 30 wt.% copper and 5-10 wt.% nickel. USE - Used as explosion-proof material. ADVANTAGE - The material: can improve the overall strength of the material and has excellent explosion-proof performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing explosion-proof material comprising (1) taking high-purity titanium, copper and nickel to the ratio as raw materials, cleaning with alcohol ultrasonic wave, blow drying and placing in an electric arc furnace, smelting at high temperature in argon atmosphere at 1200-1400 K for 3-5 hours, repeated smelting 4 times to obtain an alloy ingot, polishing to remove the oxide scale, crushing into particles and grinding into powder to obtain alloy powder, (2) adding natural graphite or artificial graphite to the mixed solution of concentrated sulfuric acid and concentrated nitric acid, where the volume ratio of concentrated sulfuric acid and concentrated nitric acid is 2:1, after stirring for 5-15 minutes, adding 0.1-3 wt.% potassium chlorate powder, continue to stir for 48-120 hours, adding 10-50 times the volume of the mixed solution to dilute with water, adding dilute hydrochloric acid to wash until no sulfate ion can be detected in the barium chloride solution, repeatedly washing with deionized water until the pH is neutral, high-speed centrifugal separating, taking the precipitate, vacuum drying to obtain graphene oxide; rapid thermal expansion of graphene oxide at 900-1050 degrees C for 10-30 seconds to obtain exfoliable graphite, adding absolute ethanol to exfoliated graphite and ultrasonic treatment for 0.5-4 hours, (3) taking 5/10-7/10 alloy powder and powdered graphene and mixing, placing into a graphite mold, using a hot press sintering furnace to sinter to obtain a preform, placing preform into a crucible, where the vacuum degree in the crucible is 0.095-0.098 MPa, heating the remaining alloy powder to 1000-1100 degrees C and maintaining for more than 10 minutes to become a molten alloy melt, passing the alloy melt into the crucible to infiltrate the preform and cool after reaching room temperature.
