Problems solved by technology

[0003] However, at present, there are few researches on the protection of penetrating poisons at home and abroad, and the PPC protection spectrum put into use is relatively limited, which can only meet the protection of perfluoroisobutylene. In my country, the developed PPC is used in protective equipment At the same time, it is packed in layers with the classic poison protection material, that is, ASZM-T impregnated carbon, so as to achieve the purpose of effective protection against classic poison and penetrating poison at the same time.
This kind of filling method has higher requirements on the design, and at the same time brings a lot of inconvenience to production and use, and the use of the product is very limited in the neighborhood, so it can only be used for collective protective equipment, but for individual protective equipment that belongs to thin layer filling equipment can not be used

Abstract

The invention relates to a toxicant prevention material, particularly to a preparation method of a composite type protective material for comprehensive toxicant prevention. The method comprises the steps as follows: (1) the composite type protective material for the comprehensive toxicant prevention comprises activated carbon serving as a carrier and an impregnant adsorbed by the activated carbon, wherein the impregnant comprises 7%-10% (by weight) of Cu, 1%-2% (by weight) of Mo, 0.6%-3% (by weight) of an active component additive Ag, 0.4%-1% (by weight) of Zn and 5%-10% (by weight) of a multi-amine compound TEDA (triethylene diamine); the content of basic cupric carbonate, ammonium molybdate, silver nitrate and zinc carbonate of the impregnant of active components are calculated according to the content of the active components such as the Cu, the Mo, the Ag and the Zn respectively. The method is reasonable in design, and the composite type protective material capable of effectively protecting against various toxicants such as classic toxicants of HCN (hydrogen cyanide) and CNCL (cyanogen chloride), a penetrating toxicant of perfluoroisobutylene and the like, is developed.

Description

technical field [0001] The invention relates to an antivirus material, in particular to a preparation method for a composite antivirus material for comprehensive antivirus. Background technique [0002] Protective impregnated activated carbon has been continuously updated with the development of the situation. After entering the 1990s, penetrating agents represented by perfluoroisobutylene (PFIB) have attracted people's attention. [0003] However, at present, there are few researches on the protection of penetrating poisons at home and abroad, and the PPC protection spectrum put into use is relatively limited, which can only meet the protection of perfluoroisobutylene. In my country, the developed PPC is used in protective equipment At the same time, it is packed in layers with the classic poison protection material, namely ASZM-T impregnated carbon, so as to achieve the purpose of effective protection against classic poison and penetrating poison at the same time. This kin...
