Abstract

The invention discloses zirconium-loaded impregnation carbon defending against HCN and CNCl toxic agents. With coconut shell broken active carbon as a carrier skeleton material, the zirconium-loaded impregnation carbon is loaded with the following components in percentage by weight: 15-20% of Cu, 1-6% of Cl<->, 0.1-5% of W, 0.1-5% of V, 0.1-5% of Ce, 2-8% of Zr and the balance of active carbon, wherein Cu comes from basic copper carbonate, Cl<-> comes from ammonium chloride, W comes from ammonium metatungstate, V comes from ammonium metavanadate or zinc ammonium metavanadate, Ce comes from cerium nitrate or cerium oxide, and Zr comes from zirconium sulfate or zirconium oxychloride. In the zirconium-loaded impregnation carbon, an active carbon carrier is loaded with active components such as Zr, W, V, Ce and Cu by adopting certain technical means and technology, and the prepared impregnation carbon material has a certain defending effect against the HCN and CNCl toxic agents.

Description

technical field

[0001] The invention relates to a filter material for protective equipment, in particular to a zirconium-loaded impregnated carbon for protecting HCN and CNCl poisons and a preparation method thereof. Background technique

[0002] Activated carbon and impregnated activated carbon are the core filter materials of protective equipment and the basis for the manufacture of protective equipment. At present, the main filling materials of protective equipment are ASC-T and ASZMT type impregnated carbon, and the main loaded active components are Cu, Mo, Zn, Ag and Cr. Although the two materials have good protective performance, they both have certain defects. For example, the active component chromium loaded in the ASC-T impregnated carbon is harmful to the human body, and it will cause environmental pollution during the preparation process. The U.S. Occupational Safety and Health Bureau has no longer provided gas masks filled with chromium-containing impregnated car...
