Anti-explosion terrace material and manufacturing method therefor

Abstract

An anti-explosion flooring material is disclosed. The material is prepared by foaming modification and rust prevention treatment of an iron alloy material and other auxiliary materials having components in percentage by weight: 85% of iron, 8% of manganese, 6% of silicon, and the remainder carbon. Because a foaming agent and rare earth are added, the static conducting performance of the flooring material is improved.

Embodiment 1: Manufacturing of the Material of the Present Invention

(3) 1) Manufacturing of iron alloy particles: iron alloy is smashed to particles of less than 100 mesh. The mass percentages of chemical components of the iron alloy are: iron 85%, manganese 8%, silicon 6%, the rest is carbon. Next, the magnetic separation is conducted using a magnetic separator, so as to remove the impurities. Next, the screening is conducted using a vibrating screen, so as to obtain iron alloy particles of about 100 mesh.

(4) 2) Foaming: the iron alloy particles material obtained in step 1) are put into a sintering pot, which is fed into a high-temperature furnace which is heated up to 1500 C.

(5) Silicon carbonate and rare earth are added. Calcinating and foaming are conducted for 30 hours. The calcinated and foamed material is cooled down quickly to the room temperature, and is smashed to about 100 mesh by a grinder, such that the material becomes porous particulate matter.

(6) 3) Modification: the particles obtained in step 2) are fed into the calcinator and heated up to 1000 C. After rare earth is added and mixed, the material is cooled down to the room temperature. After the material is smashed by the grinder, particles of 6 mesh+100 mesh are selected by the vibrating screen. Thereafter, metal aggregates exhibiting non-sparking properties, even in case of impacts and frictions, are obtained.

(7) 4) Rust-proof: the particles obtained in step 3) are fed into the calcinator again, which is heated up to 1500 C. During the calcination, inert gas is added for the rust protection. After the calcinating reaction, the material is cooled down to the room temperature. After being smashed by a grinder, particles of 6 mesh+100 mesh are selected by the vibrating screen. Thereafter, metal aggregates that have the feature of rust-proof are obtained.

(8) 5) Metal aggregates obtained in step 4) are added with silica fume, sodium nitrite, and cement, sequentially. The material is mixed well by a mixer. Thereafter, anti-explosion flooring material is obtained.
