Description
Technical field
The present invention relates to technical field of air purification, and in particular to a kind of preparation method of material for air purification.
Background technology
In recent years, with the fast development of China's city industrialization, atmosphere pollution getting worse, air quality is further disliked
Change, not only jeopardizes the normal life of people, but also cause damages to the physical and mental health of people.The closely bound up interior with people
Air quality also makes people worried, and especially various new decorative material for building especially chemical composite materials carry greatly in recent years
The toxic gases such as formaldehyde, benzene homologues, the ammonia of amount cause serious pollution to room air, eyes are dry, skin itches, has a headache,
The malaise symptoms such as failure of memory frequently occur.How such as formaldehyde, toluene, benzene volatile organic compound are efficiently removed
As researcher's focus of attention.
Absorption method is because its method is simple and the pollution-free absorption for being widely used in pernicious gas.But most adsorbents exist
The shortcomings of adsorption efficiency is low, saturated velocity is fast or cost is higher or even some can bring secondary pollution, therefore cost effective
The research and development of scavenging material easy to use are very urgent.
Material for air purification be by the harmful substance in the modes adsorption-decomposition function air such as physics, chemistry, it is net using air
It is a kind of mode of effective control air pollution source to change material.Currently, air filting material on the market is mainly with activated carbon
It is main, but normal activated carbon, based on micropore, Surface chemical functional group of wood content is few, and polarity is small, can only carry out simple physics suction
It is attached, poor selectivity, in high temperature small to nitrogen oxides, oxysulfide, heavy metal ion isopolarity pollutant adsorption capacity in air
Pernicious gas can also be discharged, can not be locked under environment.Also, it is full that activated carbon can reach absorption after adsorbing a period of time
With also pernicious gas can be released to form secondary pollution again.Therefore, the effective storage life of activated carbon is very short, and
In many cases, the release of pernicious gas is long-term, such as the complete Form aldehyde release of interior decoration at least needs several years, even
More than ten years.
It is therefore desirable to provide a kind of novel material for air purification that there is efficient removal rate, do not cause secondary pollution, with
Solve the air quality problems increasingly paid attention to.
Invention content
Present invention mainly solves the technical issues of, be with activated carbon mainly for material for air purification at present on the market
It is main, but normal activated carbon, based on micropore, Surface chemical functional group of wood content is few, and polarity is small, can only carry out simple physics suction
It is attached, poor selectivity, in high temperature small to nitrogen oxides, oxysulfide, heavy metal ion isopolarity pollutant adsorption capacity in air
Pernicious gas can also be released under environment, can not be locked or decompose, and activated carbon meeting after adsorbing a period of time
Reach adsorption saturation, pernicious gas can again be released to the defect to form secondary pollution, provides a kind of air purification material
The preparation method of material.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of preparation method of material for air purification, it is characterised in that specifically preparation process is：
（1）Count in parts by weight, by 20~30 parts of halloysite nanotubes, 40~50 parts of toluene, 20~25 parts（3- mercaptopropyis）
Trimethoxy silane is placed in three-necked flask, and heat temperature raising is heated to reflux, and obtained reflux is filtered removal filtrate, separation
Solid is obtained, is dried in vacuo, obtains sulfhydrylation halloysite nanotubes；
（2）Sulfhydrylation halloysite nanotubes, hydrogen peroxide, distilled water, methanol are mixed and is placed in single port bottle, mixed liquor, room are obtained
Under temperature under conditions of magnetic agitation rotating speed is 300~400r/min oxidation reaction, then chromium trichloride is added into single port bottle, chromium
Change reaction, filtering removal filtrate obtains filter residue, is placed in vacuum drying chamber, dry, obtains catalytic nanometer tube material；
（3）Aspen fibers by using silicon powder is put into beaker, 50~60mL sodium chlorite solutions are added into beaker, obtain mixed liquor, and
The pH of mixed liquor is adjusted with glacial acetic acid solution, isothermal holding repeats aforesaid operations 3~5 times, removes lignin, obtains comprehensive fiber
Element；
（4）With 120~150mL sodium hydroxide solutions, holocellulose is impregnated, filtering removal filtrate obtains purifying cellulose, will be pure
Cellulose is made into water slurry, is placed in ultrasonic wave plant cell pulverizer and is ultrasonically treated, and wooden nano-cellulose is made；
（5）40~50mL absolute ethyl alcohols are added into ultrasonic disperse instrument and the wooden nano-celluloses of 2~3g, ultrasonic disperse obtain
Cellulose suspension is placed in the conical flask with blender by cellulose suspension, is added into conical flask with dropping funel
18~20mL butyl titanates, while starting blender, start to stir, obtains mixed liquor；
（6）4~5mL acetic acid solutions, 20~30mL Ludox are added into above-mentioned mixed liquor, stirring obtains mixed sols, by 40
~45g catalytic nanometer tube materials are impregnated in mixed sols, and ageing obtains dry colloidal sol, dry colloidal sol is placed in electric furnace, micro- charcoal
Change, obtain charing blob of viscose, charing blob of viscose is put into mortar and is ground, sieving obtains material for air purification.
Step（1）Temperature is 100~110 DEG C after the heat temperature raising, be heated to reflux the time be 20~for 24 hours, vacuum is dry
