Description
Technical field
The invention belongs to the technical field of indoor air purification more particularly to a kind of carbon nanotube formaldehyde of radiator bottom
Eliminate the preparation method of coating.
Background technology
Formaldehyde is a kind of pollutant common in room atmosphere, it has higher toxicity.The first of short term contact low concentration
Aldehyde will stimulate eyes and respiratory tract and cause allergic reaction, and the micro formaldehyde of Long Term Contact can increase the possibility for suffering from cancer.First
Aldehyde is determined as teratogenesis shape and carcinogen by the World Health Organization.What China came into effect for 2003《Indoor air quality
Standard》(GB/T18883-2002) maximum permissible concentration of regulation formaldehyde in indoor air is that (1 hour by every cubic metre of 0.10mg
Value).It can open a window at northern summer and formaldehyde is discharged using cross-ventilation, but in winter in order to maintain indoor temperature, using warm
Gas warms oneself and closes door and window, and formaldehyde is easy to assemble indoors.
Currently, there are many ways to eliminating formaldehyde, such as 1. absorption method, 2. chemical absorption method, 3. photocatalytic method, 4. plasma
Body catalysis method, 5. Production by Catalytic Combustion Process (high/low temperature).1. absorption method is a kind of most common method for eliminating formaldehyde, this method uses
The strong sorptive material formaldehyde adsorption of bigger serface, such as strong sorptive material of common bigger serface are porous carbon
Material, activated carbon, lamellar clay, molecular sieve, activated alumina, silica gel etc., such method is simple, but its shortcoming is adsorbent
Adsorption capacity it is limited, need to regularly replace, increase eliminate formaldehyde cost；2. chemical absorption method is by formaldehyde and certain work
Property substance phase separation generate non-volatile matter, to by formaldehyde from purification object in remove, such as formaldehyde and hydroxyl sulfate it is water-soluble
Liquid effect generates nonvolatile sulfuric acid and oxime, and formaldehyde generates involatile substance with imidazolidine effect, and the method needs periodically more
Active material is changed, not only increases the cost for eliminating formaldehyde, while will produce new potential pollutant；3. photocatalytic method is to use
Titanium dioxide class catalyst oxidizes the formaldehyde into elimination, and basic principle is the hole that illumination excitation titanium dioxide generates strong oxidizing property,
Hole oxidizes the formaldehyde into the product for carbon dioxide and water, the oxygen molecule that extra oxygen source is activated from photoelectron in product, this
Method is disadvantageous in that the influence for the condition of being illuminated by the light, it is difficult to handle a large amount of formaldehyde；4. plasma-catalytic method can be
It is carried out under normal temperature and pressure conditions, but there may be ozone and nitrogen oxides in the process, and plasma apparatus is expensive, energy consumption
It is high；5. Production by Catalytic Combustion Process refers to that formaldehyde aoxidizes generation water and carbon dioxide, common mistake by oxygen molecule in the case where there is catalysts conditions
Oxidation of formaldehyde can be catalyzed by crossing metal oxide, but the complete oxidation temperature of formaldehyde and catalyst type are closely related.
Find that the patent No. 200610011398.4, Publication No. CN101028595, patent name are through retrieval：A kind of " manganese
The patent of invention of ce composite oxidation catalyst and preparation method and application ".Its specification discloses the nano combined oxygen of Mn-Ce-O
Compound, the formaldehyde remover do not use noble metal, cost is relatively low, but its catalytic activity is not high, need 100 DEG C or so could incite somebody to action
Formaldehyde complete oxidation, when use, need to provide energy warms catalyst, cause the waste of the energy.
Through retrieval it has also been found that patent No. CN200710121423.9, Publication No. CN101380574, patent name are：" one
The patent of invention of the catalyst of kind complete oxidation of formaldehyde at room temperature ".Its specification discloses Pt/TiO2Catalyst is in room temperature item
Can be efficiently by formaldehyde complete oxidation under part, but the catalyst, using the precious metals pt of higher carrying capacity, cost is higher, and
Pt is easy as catalyst by the SO in air2、NO2Equal pollutions lose activity.
