Description
Technical field
The invention belongs to the preparation field of material for air purification, particularly relate to a kind of preparation method of controllable photodegraded flexible indoor air purifying material.
Background technology
Since the nineties in 20th century, room air pollution and healthy one of the important environmental problem of national governments and public attention that becomes.Particularly in China; Along with the raising of people's living standard, interior decoration is decorated, the use of the popularizing of a large amount of electric equipment products and air-conditioning, multiple household chemicals, the architectural design style reasons such as the airtight degree increase in room that use causes with central air-conditioning; Cause a large amount of physics of indoor generation, chemistry, biology and radioactive pollution factor; Cause the serious decline of IAQ, the serious harm health has caused showing great attention to of all circles.According to World Health Organization investigation, indoorly detect more than 300 kind of pollutant, the indoor air level of pollution generally will exceed 2-5 doubly than outdoor environment, under the extreme case, can be above 100 times.And people 90% time is indoor activity, and especially baby and teenage child calculate by respiratory capacity/weight ratio, and they breathe than the adult and more many air, so more be prone to contact and suck more indoor pollutant.These pollution factors include pernicious gases such as the formaldehyde, ammonia of spread effect, and the microorganism and the bacterium of sensitization arranged, and benzene, toluene of carcinogenesis etc. are arranged.People's long term exposure can produce harmful effect to human body under these poisonous and harmful substances, even causes various diseases, therefore must purify the air of a room through material for air purification.Present indoor scavenging material mainly contains physical cleaning material, chemical cleaning method material, biological purification material three major types, and the physical cleaning material causes secondary pollution problem because the gas pollutant rate of adsorption gas pollutant desorb is taken place easily when fast and temperature is high; Biological purification material is mainly used in the restraining and sterilizing bacteria field, can not effectively remove organic pollution, though chemical cleaning method material absorption purifying effect is good, adsorption cleaning speed is adsorbed saturated slowly and easily, can not recycle, and loses efficacy easily.The novel controlled photodegradable flexible air purifying functional material that utilizes photocatalysis technology and flexible parent metal to combine to make is the advantage that has physical cleaning and chemical cleaning method concurrently; Have and use simple, advantages such as purposes is wide, good purification, long service life, so flexible air purifying material is with a wide range of applications and development prospect.
Flexible air purifying functional material preparation method mainly contains three kinds: (1) be titanium dioxide optical catalyst growth in situ with unformed shape on the flexible macromolecule base material, and then realize the crystal formation conversion of titanium dioxide.Because the general hear resistance of flexible macromolecule host material is all poor,, to realize at low temperatures the crystal formation of titanium dioxide so transforming.(2) TiO 2 sol of elder generation's preparation anatase crystal is then through padding method with TiO
2Absorption or be deposited on the flexible macromolecule base material.(3) nano titanium oxide of the Detitanium-ore-type for preparing is put in order on the flexible parent metal through coating process.
In the above-mentioned three kinds of preparation methods that reported, preceding two kinds of titanium dioxide mainly are adsorbed on the flexible macromolecule carrier by hydrogen bond, and do not have the chemical bonding effect between the flexible macromolecule base material, so the repeat performance of photochemical catalyst may be poor
[20]Coating process is because bonded dose of coating of photochemical catalyst can cause its photocatalytic activity to descend in addition.Which kind of method no matter, low and photochemical catalyst makes the problem of flexible parent metal or organic bond oxidative degradation to its adsorption efficiency all to exist photochemical catalyst under the low situation of problem, organic gaseous contamination substrate concentration concentration that how to make flexible material surface performance photochemical catalyst function.A particularly back problem; Because the strong oxidizing force of photocatalyst can make fiber or adhesive self decompose; At present flexible parent metal photooxidative degradation mechanism is lacked and understand in depth; Lack efficient ways and solve this problem, so it has seriously restricted the suitability for industrialized production of flexible air purifying functional material.
