Description
Technical Field
The invention relates to an ion compound liquid for improving comfort, a preparation method and application thereof, which are mainly applied to the environment after interior decoration and mainly relate to the field of B01D for absorbing volatile gases from air.
Background
With the development of society, people have higher requirements on living environment, the interior decoration technology of families or offices is more complex, the environmental air pollution is more serious, the existing methods for purifying the indoor environmental air are window ventilation or using air purifying agents to cover smell, the methods can not truly remove peculiar smell and have slower efficiency, the air purifying agents related to ionic liquid only simply absorb formaldehyde, toluene pollutants and have to be researched on the removal effect of other pollutants, and the effect is single and poor. The ionic liquid of the patent CN202110282769.7 is added with various plant extracts, and although the taste of the ambient air can be improved, the pollutants in the ambient air still exist, and the effect of removing the pollutants is not really realized. The ionic liquid of the patent CN201811179639.5 is added with the aldehyde scavenger and the preservative, so that the ionic liquid contains certain toxicity, and if a mistaking event occurs, the physical health of a human body is easily affected.

As a preferred embodiment, the ionic liquid a is a lipophilic ionic liquid, and the ionic liquid B is a hydrophilic ionic liquid.
As a preferred embodiment, the ionic liquid A is selected from one or a combination of a plurality of 1-butyl-3-methylimidazole hexafluorophosphate, 1-butyl-3-methylimidazole bis (trifluoromethanesulfonyl) imide salt and 1-butyl-3-methylimidazole hexafluoroantimonate.
As a preferred embodiment, the ionic liquid B is selected from one or a combination of several of 1-butyl-3-methylimidazole chloride, 1-butyl-3-methylimidazole, 1-butyl-3-methylimidazolium tetrafluoroborate, 1-butyl-3-methylimidazolium triflate, 1-butyl-3-methylimidazolium hydrogen sulfate, 1-butyl-3-methylimidazolium sulfonate, 1-butyl-3-methylimidazolium dibutyl phosphate, 1-butyl-3-methylimidazolium dicyano salt and 1-butyl-3-methylimidazolium nitrate.
As a preferred embodiment, the ionic liquid can remove indoor decoration pollutants and at least comprises one of formaldehyde, benzene, toluene, xylene, ammonia and VOC.
As a preferred embodiment, the nano metal oxide is selected from one or a combination of several of nano tungsten trioxide, nano aluminum oxide, nano silicon dioxide and nano vanadium oxide.
As a preferred embodiment, the nano metal oxide has a particle size of 10 to 30nm.
The applicant finds that the particle size of the nano tungsten trioxide is 10-30nm in the experimental process, so that the adsorption effect of the ionic liquid on pollutants can be improved, and the possible reasons are hypothesized to be: the nanometer tungsten trioxide with the particle size of 10-30nm is dispersed in the ionic liquid to form uniform pore diameter, a large amount of pollutants can be absorbed into the ionic liquid, and then the ionic liquid can be subjected to catalytic reaction with the absorbed air pollutants to decompose the air pollutants into carbon dioxide and water, so that the effect of purifying the ambient air is achieved. If the tungsten trioxide is out of the preferred range, the tungsten trioxide has very low solubility in the ionic liquid, so that the tungsten trioxide cannot stably exist in the ionic liquid, and after a period of time, the problem of layering possibly occurs, thereby affecting the removal effect of air pollutants.
As a preferred embodiment, the ionic liquid has a loss rate of 0.1-1% after use and can be recycled.
As a preferred embodiment, the penetrating agent is selected from one or a combination of several of laurocapram, dimethyl isosorbide, N-alkyl benzisothiazolinone, cyclohexanethol, tetrahydropiper nigrum and sodium alginate.
As a preferred embodiment, the ion compound liquid is treated to release nontoxic and harmless carbon dioxide and water.
The second aspect of the invention provides a method for preparing an ion compound liquid for improving comfort, comprising the following steps:
(3) Heating the ionic liquid A to 115-125 ℃, adding nano metal oxide and penetrating agent, and stirring and mixing to obtain a mixed liquid 1;
