Abstract

The invention relates to an anti-poison mask with a metal organic framework adsorption material. The anti-poison mask with the metal organic framework adsorption material mainly solves the problems that in the prior art, the adsorption capacity is poor, and the adsorption range is narrow. By the adoption of the anti-poison mask with the metal organic framework adsorption material, a filtering material of the anti-poison mask comprises non-woven fabric and metal organic framework material layers, and the metal organic framework material layers are arranged between the two layers of non-woven fabric. The metal organic framework material layers are one or more non-woven fabric layers with a certain metal organic framework material loading capacity. The metal organic framework material is a three-dimensional framework crystal material which is formed by self-assembly of metal ions and organic ligands containing oxygen and nitrogen. By means of the technical scheme characterized in that -NH2 and -OH functional groups are added to an organic ligand framework to form the MOFs preferential adsorption material in a composite mode, the problems are preferably solved, and the anti-poison maskcan be used in anti-poison tools.

Description

technical field [0001] The invention relates to a gas respirator containing a metal organic framework adsorption material. Background technique [0002] In the chemical industry, emergency places for dangerous goods leakage, and in the process of people's production, use, storage and transportation of chemicals, toxic gases will inevitably be diffused into the environment. If it enters the human body through the respiratory system, it will cause poisoning and even life-threatening. The gas mask can filter the toxic gas in the environment to a certain extent, reduce or avoid the harm of toxic chemicals to the human body. [0003] The adsorption material is the key to whether the gas mask can effectively filter toxic gases. The adsorption filter material in the gas mask commonly used at present is activated carbon. Because activated carbon has a well-developed pore structure, it can fully contact with toxic and harmful gases in the environment and absorb them into the pores ...
