Description
Technical field
The present invention relates to active carbon and its preparation technical fields, more particularly to a kind of filter core material for air purifier
Material.
Background technique
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 lower and lower, existing main influence people
The air pollutants of class living environment include following several: the volatile organics such as formaldehyde, toluene that 1. indoor decoration pollutions generate
Pollutant；2. particulate pollutants such as indoor and outdoor PM2.5；3. microbial contaminations such as indoor bacteria, fungies；The sucking of these pollutants
The not only respiratory system of damaged human but will be deposited in human body, become the carrier of the noxious materials such as aromatic hydrocarbons, heavy metal, be threatened
Human health.Before 2010, Chinese air purifier market is mainly used for industry and depollutes and the professional domains such as medical, market
Scale is relatively small, increasess slowly.After 2010, since haze weather is serious, Chinese air purifier starts for civilian city
?.Since 2013, explosive growth was presented in air purifier market, gradually returned rationality to industry development in 2016, on
Half a year air purifier sales volume is up to 2,260,000, and sales volume is 5,300,000,000 yuan, according to middle throwing consultant industrial research Center Prediction, to 2020
Year, market scale is up to 34,000,000,000 yuan.About 1000 or more air purifier enterprises at present, 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
A large amount of people is dead due to room air pollution, therefore the improvement of room air pollution is very urgent.Nocuousness in room air
Substance mainly includes formaldehyde, benzene, radon, flue dust etc..For the above pollutant is handled, most commonly seen means are using air cleaning
Agent, present air purifying preparation can substantially be divided into chemical type cleanser and plant type cleanser.Wherein, chemical type cleanser by
, removal effect simple in its preparation process 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 being used for a long time, and the killing effect to virus, bacterium and pathogenic bacteria of chemical type cleanser
It is weaker, it is not able to satisfy the various demands of people.The purified treatment effect of present plant type cleanser is limited, and prepares work
Skill is complicated, high production cost, limits it and further promotes.
A kind of compound air purification filter paper material is disclosed application No. is the Chinese patent of CN201610865906.9 and is answered
With its filter core, the compound air purification filter paper material includes the activated carbon fibre pre-filtering being superposed 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, and activated carbon fibre pre-filter layer is equipped with, 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 peculiar smell in environment is significantly improved, is conducive to improve entire filter core to gaseous state
Contaminant molecule removal rate.Application No. is the Chinese patents of CN201510131107.4 to disclose a kind of long-acting sky except formaldehyde
The preparation method of gas purifier material for core, this method are to use souring activity charcoal with SOCl2 modification, by nano-manganese dioxide
It is silane coupler modified；Then modifiedization active carbon and modified nano-manganese dioxide are crosslinked, obtain one kind
The long-acting air purifier material for core except formaldehyde.Active carbon is not only used as adsorbent in the present invention, but also as warm catalyst nanometer
The solidified carrier of catalyst has simple process, performance long-acting, safety and environmental protection except formaldehyde performance.
To sum up, the filter element for purifier that existing conventional air purifier class product uses is often that active carbon etc. is similar
Particle is distributed in the plastic part with honeycomb, although there is removal to make the gas with foreign flavor such as formaldehyde in indoor environment
With, but it is limited by such structure limitation, it can not achieve the function for the purification that quickly eliminates the unusual smell.Therefore, there is an urgent need to have
The compound air purification filter core of effect removal toxic and harmful gas and the function that eliminates the unusual smell, realizes the fast and effective purification to environment.
Summary of the invention
