Description
Technical field
The present invention relates to activated carbon and its preparing technical field, more particularly to a kind of filter core material for air purifier
Material and preparation method thereof.
Background technology
Modern society's industry is more and more flourishing, and human lives are increasingly excellent convenient, but our living environment is increasingly
Difference.In recent years, with the aggravation of environmental pollution, air quality for the survival of mankind is also more and more lower, existing main influence people
The air pollutants of class living environment include following several：1. the volatile organic such as formaldehyde, toluene caused by indoor decoration pollution
Pollutant；2. the particulate pollutants such as indoor and outdoor PM2.5；3. the microorganism pollutions such as indoor bacteria, fungi；The suction of these pollutants
It the not only respiratory system of damaged human, can more be deposited in human body, turn into the carrier of the noxious materials such as aromatic hydrocarbons, heavy metal, threaten
Human health.Before 2010, Chinese air purifier market is mainly used in industry and depolluted and the professional domain such as medical, market
Scale is relatively small, increasess slowly.After 2010, because haze weather is serious, Chinese air purifier starts to be used for civilian city
.Since 2013, explosive growth was presented in air purifier market, and rationality is gradually returned to industry development in 2016, on
For half a year air purifier sales volume up to 2,260,000, sales volume is 5,300,000,000 yuan, according to middle throwing consultant's industrial research Center Prediction, to 2020
Year, market scale is up to 34,000,000,000 yuan.Current about more than 1000 air purifier enterprise of China, in the long run, in
State's air purifier market demand is huge.Room air pollution is possible to can not be ignored to injury caused by human body, has every year
Substantial amounts of people is dead because of room air pollution, therefore the improvement of room air pollution is very urgent.It is harmful in room air
Material mainly includes formaldehyde, benzene, radon, flue dust etc..For handling above pollutant, most commonly seen means are to use purification of air
Agent, present air purifying preparation can substantially be divided into chemical type cleanser and plant type cleanser.Wherein, chemical type cleanser by
In its preparation technology is simple, removal effect preferably and use is more universal, can be to ring but due to the toxicity of chemical reagent itself
Secondary pollution is caused in border, is unfavorable for long-term use, and the killing effect to viral, bacterium and pathogenic bacteria of chemical type cleanser
It is weaker, it is impossible to meet many demands of people.The purified treatment effect of present plant type cleanser is limited, and prepares work
Skill is complicated, and production cost is high, limits it and further promotes.
Application No. CN201610865906.9 Chinese patent discloses a kind of compound air purification filter paper material and should
With its filter core, the compound air purification filter paper material includes being superimposed the NACF pre-filtering set with random order
Layer, adsoption catalysis stratum granulosum, particulate matter filter layer and sterilization supporting layer.This compound air purification filter paper material and existing filter paper
Material is compared, provided with NACF pre-filter layer, the air purifying filter core energy prepared with this compound air purification filter paper material
The fast purification absorption property to contaminant molecules such as the peculiar smell in environment is significantly improved, is advantageous to improve whole filter core to gaseous state
Contaminant molecule removal rate.Application No. CN201510131107.4 Chinese patent discloses a kind of long-acting except the sky of formaldehyde
The preparation method of gas purifier material for core, this method are to use souring activity charcoal with SOCl2 modifications, by nano-manganese dioxide
It is silane coupler modified；Then modified change activated carbon is crosslinked with modified nano-manganese dioxide, obtains one kind
It is long-acting except the air purifier material for core of formaldehyde.Activated carbon is both used as adsorbent in the present invention, is used as warm catalyst nanometer again
The solidified carrier of catalyst, has that technique is simple, performance is long-acting, safety and environmental protection removes formaldehyde performance.
To sum up, the filter element for purifier that existing conventional air purifier class product uses is often that activated carbon etc. is similar
Particle is distributed in the plastic part with honeycomb, is made although having to remove to gas with foreign flavor such as the formaldehyde in indoor environment
With, but it is limited by such a structure limitation, it is impossible to realize the function for the purification that quickly eliminates the unusual smell.Therefore, there is an urgent need to having
Effect removes toxic and harmful gas and the compound air purification filter core for the function that eliminates the unusual smell, and realizes the fast and effective purification to environment.
