Description

Gas defence personal protective equipment containing MOFs adsorbent
Technical field
The present invention relates to a kind of gas defence personal protective equipment containing MOFs adsorbent.
Background technique
In chemical industry, dangerous material leakage emergency place and in the mistake of people's production, use, storage and transporting Chemicals Cheng Zhong, toxic gas can be inevitably flooded in environment.If entering human body by respiratory system, poisoning can be caused very To threat to life.And breathing mask protective articles can filter the toxic gas in environment to a certain extent, be reduced or avoided Harm of the toxic chemical to human body.
Adsorbent material is the key that can protective articles breathing mask effectively be used in filtering poisonous gas, currently used protection Absorption filtering material in product breathing mask is active carbon.Since active carbon has flourishing pore structure, can in environment Toxic and harmful gas come into full contact with and be adsorbed in active carbon hole, to achieve the purpose that filtering poisonous gas.But Due to commonly using the lower (400-1000m of active carbon specific surface area2/ g), its adsorption capacity to toxic gas is limited, this just makes It obtains active carbon protective articles breathing mask to be easy to be adsorbed saturation, or even cannot in the environment containing high concentration noxious gas It uses.In addition, in most cases, containing there are many toxic gases in chemical company or dangerous material leakage site surrounding, in order to make Active carbon has broader adsorption capacity to a variety of toxic gases, usually acid, alkali, metal salt is carried out to active carbon, to inhale Toxic gas of different nature in follower ring border.But after carrying out acid, alkali modification respectively to active carbon, the soda acid official on active carbon It can react to each other between group, to reduce the adsorption reaction ability with toxic gas, not can effectively improve active carbon Adsorb width.
Metal-organic framework materials (MOFs) are a kind of novel stephanoporate framework materials, it is to be matched by metal ion with organic The three-dimensional network skeleton crystalline material that body is self-assembly of.MOFs material is as a kind of novel functional molecular material, with biography System active carbon, zeolitic material are compared, and have many advantages.Huge specific surface area (3000-10000m2/ g), high porosity can To make it have very high adsorption capacity；Adjustable pore size, the skeleton structure of multiplicity can carry out selective absorption；It can modify Functional group's hole surface, ligand unsatuated metal point can increase the affinity with gas molecule；Stiff stability can make its into Row repeatedly absorption, still keeps the integrality of skeleton structure.In addition, carrying out soda acid since MOF material skeleton structure is fixed to it and repairing Decorations, can be such that functional group of different nature is separately fixed on skeleton, be unlikely to material itself and acid-base reaction occurs.It is this simultaneously The MOFs material of compound with regular structure with soda acid characteristic can react with soda acid toxic gas respectively, have broader gas defence Ability.It, can be by MOFs powder load in ventilative, soft, easily cutting molding since MOFs material is a kind of crystal powder material Carrier (such as non-woven fabrics) on, in protective articles, the structure feature that MOFs material can be kept original in this way to make MOFs Material has optimal adsorption performance.
Therefore, exploitation has the individual protection based on metal organic framework adsorbent material of high adsorption capacity and wide adsorption range Articles filter the toxic gas in environment, make human body from the harm of toxic gas, be very valuable.
Summary of the invention
