Description
Technical field
The present invention relates to a kind of preparation method of water-based system with the modified nano composite material of purification air, belong to nanometer
Functional material and technical field of surface.
Background technology
All one's life of people most time live and works indoors, the environmental pollution that interior decoration is caused cause people's disease,
Residual, dead phenomenon has become social concern, and indoor environmental pollution is put into one of " ten big killers ", these dusty gas
It is very big to body effect, breathing problem, cancer, leukaemia, sacred disease are easily caused, especially pregnant woman, children, old man are endangered
Evil is serious.
Generally, people get used to finishing rear venting two months, then move in.But, indoor decoration pollution be mainly formaldehyde,
The chemical pollutants such as benzene, ammonia, this pollutant acquisition time is for up to 15 years, can just solve problem within two months absolutely not, in full summer
In the closed room of air-conditioning and severe winter heating, due to lacking outdoor fresh air, its harm is more serious！When your in new clothes long period
During the ground such as the new family repaiied or new office, hotel, meeting room, furniture design and making, building materials market, you whether have headache, dim eyesight,
The symptoms such as cough, uncomfortable in chest, Nausea and vomiting, caused by these are all indoor stealthy killer's air pollutants.The master of room air
Pollute in building, decoration and the material such as furniture, including formaldehyde, benzene, ammonia etc., wherein danger of the formaldehyde pollution to health
Evil is maximum.
The method of purification air has in the market：1st, bamboo charcoal, active carbon adsorption, but the energy of adsorption of bamboo charcoal, activated carbon
Power is very limited, only there is some effects to benzene, and the adsorption effect of PARA FORMALDEHYDE PRILLS(91,95) is simultaneously bad, and there is the problem of absorbing saturation, temperature
Uptake is relatively large when low, and temperature rise can be discharged again.
2nd, formaldehyde scavenger or formaldehyde lyase, these are " to remove " formaldehyde by the method chemically reacted, this method
Essence is that target substance is reduced into toxicity or innocuous substance is converted into, and formaldehyde can be oxidized to formic acid, can also be reduced to
Methanol, the toxicity of both materials is still present, and easily causes secondary pollution., can be with such as the formaldehyde scavenger of some strong oxidizing properties
Oxidation of formaldehyde, but itself easily decomposes, timber can be damaged and do not say by being sprayed on plank, and just lose efficiency within a few hours,
It can not possibly realize " spray is escaped forever ".Moreover the scavenger spray of high concentration is in atmosphere, and new contamination hazard can be produced to people, other
Oxidant, reducing agent also can not effectively remove formaldehyde, and can introduce similar secondary pollution.
3rd, catalysis material, refers in the presence of light and occurs photochemically reactive based semiconductor catalyst material, including
The many oxides such as titanium dioxide, zinc oxide, tin oxide, zirconium dioxide, cadmium sulfide, sulfide semiconductor, especially nanometer two
Titanium oxide application is most；For in theory, photocatalyst is a kind of top quality except formaldehyde products, and in fact photocatalyst will be played
Effect, will have ultraviolet to excite, photocatalyst does not have any effect in night and without visible ray, and can not possibly be always in room
There is ultraviolet, especially in some drawers, light is even more can not see in the place of the Form aldehyde release most serious such as cupboard back side,
Which limits the effect of photocatalyst.Secondly, different types of photocatalyst effect is also different, and just same kind of light is touched at last
Matchmaker, granular size also determines actual effect, in general better (the nano-TiO of the smaller effect of particle2Average grain diameter exist
Within 10nm just effectively).The particle of other photocatalyst is very small, is easily suspended in air, can not be used just as dust
Naked eyes are seen, even if suction can not also be discovered, easily cause secondary pollution, it is most likely that human lung is damaged.Also light
Catalyst has the performance of decomposition of organic matter, has infringement to any organism such as real leather products, hair grass and high-grade clothes, skin
Effect, and photocatalyst manufacturer avoids all mention of, and does not also inform consumer, as long as or even the photocatalyst that misguides the consumer have light all right,
Such behavior, should be scolded.Actually photocatalyst is limited to removing the dusty gas effect in air, therefore developed country's mesh
It is preceding seldom to use them as civilian catalysis material.
