Abstract

The invention relates to a protective material, in particular to a preparation method of a protective material for perfluoroisobutylene. The preparation method comprises the steps as follows: the protective material for perfluoroisobutylene comprises activated carbon serving as a carrier and an impregnating compound for activated carbon adsorption, wherein the impregnating compound comprises the components in percentage by weight as follows: 3%-10% of Cu, 0.1%-5% of Zn and 4%-9% of polyamino compound TEDA (triethylene diamine); and the impregnating compound containing the components, namely, basic cupric carbonate and zinc carbonate, are added into ammonium hydroxide, the quantities of basic cupric carbonate and zinc carbonate are calculated receptively according to the content of the active components Cu and Zn, heating and dissolving are performed to prepare an impregnation liquid, the temperature of the mixed solution is maintained in a range from 60 DEG C to 80 DEG C, when the impregnating compound is sufficiently dissolved, an equivalent impregnation method is adopted to uniformly mix the impregnating compound with the activated carbon for still standing for 1-2 hours. The preparation method of the protective material for perfluoroisobutylene is reasonable in design, the activated carbon is adopted as a carrier framework material and loaded with metallic active components such as Cu, Zn and the like, and protective material for perfluoroisobutylene and the preparation method of the protective material for perfluoroisobutylene are provided.

Description

technical field [0001] The invention relates to a protective material, in particular to a preparation method of a perfluoroisobutylene protective material. Background technique [0002] Perfluoroisobutylene (PFIB) has high toxicity, about ten times that of phosgene, and it is easy to penetrate gas masks under high humidity conditions, and is considered to be a very threatening potential chemical agent. It is a by-product of the organic fluorine industry, has sufficient sources, and may be used as an emergency poison, so it has received extensive attention from the chemical defense community. The Chemical Weapons Agreement (CWC) lists it as one of the strictly controlled chemical hazards, and it is also included in our poison protection spectrum as an emergency poison. Therefore, the protection and elimination of PFlB has always been an important topic in the field of chemical defense research. [0003] Canada and other countries have carried out a lot of research on penetr...
