Preparation method of impregnated carbon for protecting N2O4 and UDMH toxic agents

Abstract

The invention discloses a preparation method of impregnated carbon for protecting dinitrogen tetroxide (N2O4) and unsymmetrical dimethyl hydrazine (UDMH) toxic agents, which solves the problems that canisters in which different compounds are filled are required to protect the N2O4 and the UDMH respectively and are inconvenient to carry and use. The method comprises the following steps of: solution preparation: adding basic cupric carbonate and an alkaline compound according to copper content of between 4.0 and 6.0 percent and alkali content of between 3.0 and 5.5 percent in a finished product, adding ammonia water and distilled water according to water capacity of active carbon, and adding 1.0Kg of silver nitrate into every 1,000L of solution to prepare mixed solution; twice impregnation and twice calcination; and sieving of objects calcined twice to obtain the impregnated carbon for protecting the N2O4 and UDMH toxic agents. Compared with the prior art, a copper-containing compound, an alkali and a silver-containing compound are used as raw materials on the basis of selecting active carbon; the raw materials are impregnated according to a proper proportion to prepare the impregnated carbon; thus the impregnated carbon has effects of physical adsorption and catalytic conversion on hydrazines and has the effect of catalytic conversion on a nitro-oxidizer.

Description

Technical field

[0001] The invention relates to the field of impregnated carbon, in particular to the protection of N 2 O 4 And unsymmetrical dimethylhydrazine (UDMH) preparation method of impregnated carbon for poison. Background technique

[0002] Dinitrogen Tetroxide (N 2 O 4 ) And UDMH is one of the most common and most used two-component self-igniting propellants. However, N 2 O 4 Both UDMH and UDMH are toxic gases that are harmful to the human body, and they are often produced at the same time. When protecting, generally by wearing two different types of canisters to protect N 2 O 4 And UDMH's harm to the human body. The canister for protecting UDMH uses Cu and Ag compounds to protect N 2 O 4 The canister uses carbon compounds. There is no substance that can protect N at the same time 2 O 4 And UDMH, so canisters with different compounds must be used to protect N 2 O 4 And UDMH, in the specific use, there is a problem that it is inconvenient to carry and use.
