Description
Technical field
The present invention relates to air purification field, specifically a kind of indoor material for air purification.
Background technique
In recent years, as the fast development of China's city industrialization, atmosphere pollution are got 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, requirement of the people to air cleaning
Also higher and higher.With people closely bound up indoor air quality also makes people worried, and especially this year fills with building decoration
The extensive use of material is repaired, a variety of materials release a large amount of harmful substance (such as：The volatility organic contamination such as formaldehyde, toluene, benzene
Object) it seriously polluted indoor air environment, and then the health and working efficiency of the mankind are had an important influence.
" room air pollution " is classified as after " coal smoke type ", " photochemical fog type " pollution by International Environmental Protection expert
Third generation air pollution problems inherent.People have been carried out many researchs in terms of air cleaning, develop various with purification air
The material of function, but existing material for air purification mostly uses adsorption filtration and titanium dioxide to carry out light catalytic purifying, inhales
Attached filtering needs to be replaced frequently scavenging material, and the surface of titanium dioxide is reunited as time goes by, reduces photocatalytic activity,
This is just that the use of people brings inconvenience.
Summary of the invention
It is mentioned above in the background art to solve the purpose of the present invention is to provide a kind of indoor material for air purification
Problem.
To achieve the above object, the present invention provides the following technical solutions：
A kind of indoor material for air purification, the raw material including following parts by weight：23-35 parts of tourmaline powder, medical stone powder
18-24 parts, 6.5-9.6 parts of Nano chitosan, 2.4-4.5 parts of polyacrylamide, 4-6 parts of plant amylum, carrotene 3.3-5.2
Part, 6-8 parts of daisy, 5.3-7.6 parts of cordate houttuynia and 32-44 parts of isopropanol.
As a further solution of the present invention：Plant amylum includes that green starch, cornstarch, starch from sweet potato and sorghum are formed sediment
At least two in powder.
As a further solution of the present invention：The relative molecular weight of Nano chitosan is 6-12 ten thousand.
As a further solution of the present invention：The partial size of tourmaline powder is 0.06-0.24mm, and the partial size of medical stone powder is
0.16-0.36mm。
The preparation method of the indoor material for air purification, specific step is as follows：
Step 1 is cleaned daisy, chopping, and the mass fraction that 4-6 times of its quality is then added is the citric acid of 26-38%
Aqueous solution, uses extracting through microwave heating 2-3 times after impregnating 2-3 hours, and filtering obtains daisy extracting solution；
Step 2, cordate houttuynia are extracted 2-3 hours with alcohol reflux after being washed and chopped, extract 3-4 times, refrigerate 4-8 hours, mistake
Filter, filtrate are recovered under reduced pressure ethyl alcohol, obtain Herba Houttuyniae extract；
Step 3, by medical stone powder, Nano chitosan, plant amylum and Herba Houttuyniae extract mix and ultrasonic disperse,
Then it is aged 10-16 hours at room temperature, obtains the first mixture；
Tourmaline powder, carrotene and isopropanol are stirred evenly with the revolving speed of 180-300rpm, obtain second by step 4
Mixture；
Step 5 will stir evenly under daisy extracting solution and polyacrylamide room temperature, then stand 3-6 hours under room temperature,
Obtain third mixture；
First mixture, the second mixture and third mixture are stirred evenly in blender, are then led to by step 6
It crosses pelletizer and is prepared into the particle that partial size is 1.5-3.6mm to get finished product is arrived.
As a further solution of the present invention：The power of ultrasonic disperse is 180-260W, the frequency of ultrasonic disperse in step 3
Rate is 16-20KHz.
As a further solution of the present invention：It is 12- that tourmaline powder and medical stone powder are immersed in mass fraction before use
50-80 minutes in 16% hydrochloric acid solution, then irradiated 8-14 minutes under the microwave of 860-1360MHz.
Compared with prior art, the beneficial effects of the invention are as follows：Raw material sources of the present invention are extensive, by using tourmaline,
Medical stone etc. can discharge the raw material of anion and far infrared, then make with the Nano chitosan cooperation with good adsorption function
With, then be modified with daisy extracting solution, carrotene etc., uniform tiny micropore is formd on surface, overcomes clustering phenomena,
Increase the contact probability with pollutant, has good degradation efficiency to the organic pollutant in air, effective time is lasting, makes
It is good with effect.
