Description
Technical field
The present invention relates to a kind of preparation methods of multiple-effect, environmentally-friendly eliminating smell agent, belong to technical field of air purification.
Background technique
In family daily life, main stink comes from toilet, kitchen, shoe chest, rubbish, pet, smoking etc., such as
For in family bathroom space, tight due to closing, air stream moment, most sewer pipeline of toilet are without sealing device or sealing effect
Difference causes peculiar smell in toilet, these smell components are mainly hydrogen sulfide, ammonia, sulfur dioxide etc., these gases both influence people
Body health, and influence living environment and life grade.In addition various peculiar smell, example all be may be simultaneously present in public places
There are smoke, vinosity, stink with perspiration, bed body smell, peculiar smell of pet, vomiting peculiar smell, toilet peculiar smell, carpet musty, sky if the room KTV
Adjust peculiar smell or even construction decoration material coating peculiar smell, paint peculiar smell, viscose wallpaper peculiar smell.
In addition, maximum finishing pollution is exactly formaldehyde in finishing at present, formaldehyde can cause the disease of respiratory tract and nervous system
There are the symptoms such as cough, pharyngalgia, uncomfortable in chest, dizziness and nausea, weakness of limbs, expiratory dyspnea, drowsiness in disease.Even more serious induction nose
Cancer, the cancers such as throat cancer, cutaneum carcinoma and leukaemia occur.Room and the formaldehyde of automobile lining quite have the body of people
Harm, so, have to the content for taking method appropriate to reduce formaldehyde.
The most common deodorizing method is exactly to spray air freshener, and most of air fresheners are by ether, essence on the market
Etc. the synthesis of various chemical components, there is no resolving harmful gas, carry out covering smell simply by fragrance is distributed, by obscuring people's
Peculiar smell is desalinated in smell, the gas inherently air pollutants that these substances generate after chemical breakdown in air, instead
The degree of room air pollution is exacerbated, long-time service can generate pessimal stimulation to human body, and aromatic inferior can also be to the mind of people
Harm is generated through system.Moreover, the harmful substances such as normal air freshener PARA FORMALDEHYDE PRILLS(91,95) do not have any effect, therefore by with fresh air
Treated that air quality is difficult the requirement for meeting people to air quality for agent.
It would therefore be desirable to which a kind of can effectively remove harmful substance in peculiar smell and air, and residue will not to human body
Generate the environmentally friendly eliminating smell agent of injury.
Summary of the invention
The technical problems to be solved by the invention：It for most of air fresheners is on the market closed by various chemical components
At, there is no resolving harmful gas, and can aggravate the degree of room air pollution, and long-time service can generate human body bad
Stimulation, the harmful substances such as PARA FORMALDEHYDE PRILLS(91,95) do not have the problem of any effect, provide a kind of preparation method of multiple-effect, environmentally-friendly eliminating smell agent.
In order to solve the above technical problems, the technical solution adopted by the present invention is that：
（1）By Mg（NO3）2·6H2O,Al（NO3）3·9H2O and deionized water mixing, 10~15min of ultrasound obtain mixed solution,
By the sodium hydroxide solution of mixed solution and 1mol/L simultaneously be added drop-wise in tripolyphosphate aluminum solutions, maintenance system pH value be 9~
11, constant temperature stirring obtains suspension, by suspension still aging 18~for 24 hours, obtains aged substance, washed aged substance with deionized water
To neutrality, it is placed in 60~80 DEG C of baking ovens and dries to constant weight, obtain adsorbent material；
（2）According to parts by weight, 10~20 parts of active carbons, 10~20 parts of adsorbent materials, 10~20 parts of peats, 8 are weighed respectively
~20 parts of deionized waters, 6~12 parts of silica gel lotions, 4~8 parts of sodium bicarbonates, 0.2~0.5 part of antioxidant, 0.2~0.4 part of dispersion
Agent, by active carbon, adsorbent material, peat, silica gel solution, deionized water, sodium bicarbonate, antioxidant and dispersing agent, mixing is stirred
Processing is mixed, combination product is obtained, combination product is placed in 50~60 DEG C of baking oven and is dried to constant weight, obtain multiple-effect, environmentally-friendly eliminating smell agent.
Step（1）The Mg（NO3）2·6H2O,Al（NO3）3·9H2O and deionized water in mass ratio 1: 1: 10 mix.
Step（1）The described constant temperature stirring stirs 20~30min for constant temperature at being 80~90 DEG C in temperature.
Step（2）The antioxidant is 2,6- three-level butyl -4- methylphenol, double（- 4 hydroxy benzenes of 3,5- three-level butyl
Base）One of thioether, four (β-(3,5- three-level butyl -4- hydroxy phenyl) propionic acid) pentaerythritol esters.
Step（2）The dispersing agent is glyceryl monostearate, in vinyl bis-stearamides, glyceryl tristearate
One kind.
Step（2）To mix active carbon, adsorbent material and peat, low whipping speed is for the mixing processing
Under 800~1200r/min, 5~10min is mixed, obtains mixture, silica gel solution, deionized water, carbon are added in the mixture
Sour hydrogen sodium, antioxidant and dispersing agent, low whipping speed are that 1~2h is mixed under 80~120r/min.
The present invention is compared with other methods, and advantageous effects are：
（1）The present invention is combined using physical absorption and chemisorption and is prepared for a kind of multiple-effect, environmentally-friendly eliminating smell agent, physical absorption master
If chemisorption is mainly main inhale with aluminium triphosphate intercalated houghite using active carbon, peat as primary attachment material
Attached raw material, the eliminating smell agent of preparation have the advantages that adsorption rate fastly and large amount of adsorption, the humic acid in peat be it is a kind of naturally
Organic matter, there are H in humic acid molecule3O+And non-ionic COOH base and COO-Ion has certain absorption to make alkaline gas
With, and it is nontoxic, and have sterilizing ability, when being ground to 80 mesh or so, state is quite similar with active carbon,
Also it is in porous type, has good adsorption effect to gas and heavy metal ion；
（2）Coprecipitation of the present invention prepares aluminium triphosphate intercalated houghite, and aluminium triphosphate dissolves under alkaline condition, release
Triphosphate ion out enters hydrotalcite layers in the form of ion exchange, and silica gel is a kind of high activity adsorbent material, to moisture
Son has good affinity, and the chemical constituent and physical structure of silica gel make it have absorption property height, and thermal stability is good, changes
It learns property to stablize, there is higher mechanical strength, sodium bicarbonate is added in the present invention as pore creating material, making the eliminating smell agent of preparation is to be in
Porous form, enhance its adsorption capacity.
