Description
Technical field
The invention belongs to field of environment protection, and in particular to a kind of coating with air-cleaning function.
Background technology
International Environmental Protection expert is classified as " room air pollution " after " coal smoke type ", " photochemical fog type " pollution
Third generation air pollution problems inherent.People have been carried out many researchs in terms of purification of air, develop various with purify air
The material of function, such as Chinese patent CN102584113B are prepared in environmental protection using raw materials such as kieselguhr, attapulgite, rubber powders
Wall coating, but the invention does not carry out necessary modification to kieselguhr, attapulgite, and rubber powder itself is just with formaldehyde etc.
Organic volatile, and many micropore shape features of diatom ooze also can be sealed by colloid and have no way of play adsorption function, cause purification
It is inefficient.Chinese patent CN105218033A is prepared for the bentonite colour-wash powder with air purification function, the invention
The materials such as colored portland cement, nano titanium oxide are used, and cement can block the invention completely and rely to play and adsorb
The hole of effect material, evaluated report is confirmed nano titanium oxide with experimental principle at present：" nano titanium oxide " is to experiment
Animal has carcinogenecity for room, it is possible to cause human carcinogen（Probability is 2B levels）.
The content of the invention
The invention aims to overcome existing material for air purification purification efficiency not high, the defect with hazardness,
There is provided a kind of without rubber powder, cement for people, purification efficiency is high, nonhazardouss, the free of contamination coating with air-cleaning function.
The purpose of the present invention is realized by following proposal.
The coating with air-cleaning function of the present invention, it is characterised in that the coating with air-cleaning function
Composition is as follows：
Modified alta-mud formaldehyde adsorbent 30% ~ 50%, modified alta-mud 5% ~ 10%, modified meerschaum 10% ~ 20%, Kaolin 10% ~
20%, nano silver-carrying antiseptic 0.2% ~ 1%, titanium dioxide 4% ~ 8%, Calcium Carbonate 5% ~ 15%, kieselguhr mine tailing 2% ~ 6%, Methyl cellulose
Element 1% ~ 5%, the wood fiber 0.3% ~ 1%.
In such scheme, the modified alta-mud formaldehyde adsorbent is that bentonite is heated in sulphuric acid or hydrochloric acid, then Jing
Microwave radiation and obtain.
In such scheme, it is 24 by bentonite and sodium carbonate or sodium fluoride in mass ratio that the modified alta-mud is:1 mixes
Reaction 7 days is closed, be dry, pulverize to 320 mesh at 80 ~ 100 DEG C and obtained.
In such scheme, the modified meerschaum is to crush meerschaum, acidified process, then at 200 ~ 300 DEG C
Roasting and obtain.
The coating with air-cleaning function of the present invention, its preparation method is：
Weigh by formula, modified alta-mud formaldehyde adsorbent, modified alta-mud, Kaolin are thrown in and is sufficiently stirred in blender
5 minutes, then will be modified meerschaum, nano silver-carrying antiseptic, titanium dioxide, Calcium Carbonate, kieselguhr mine tailing, methylcellulose, wood fine
Dimension is thrown in into the common mix homogeneously of blender and is stirred 10 minutes, obtains the coating with air-cleaning function of powder.
The coating with air-cleaning function of the present invention, its using method is：
By the coating with air-cleaning function and water in mass ratio 1:1 ratio mix homogeneously, is brushed on wall.
Used by of the invention, the preparation method of modified alta-mud formaldehyde adsorbent presses Chinese patent application 201610244147.4
Operation, by montmorillonite（Bentonite）Activation modification, and belong to layer aluminosilicate for montmorillonite, which is by two silica
Tetrahedron presss from both sides the 2 of one layer of alumina octahedral composition：1 type crystal structure, is adsorbed with calcium, magnesium, potassium, sodium between its montmorillonite layered framework
Etc. these notable construction featuress of cation, activation modification is carried out to bentonite, these cationes are replaced dissolution by hydrion so as to
Chemism is produced, while by a pair of aluminium ions in montmorillonite octahedral structure and two pairs of hydroxy dissolutions, in making montmorillonite
Lattice spacing increase, specific surface area increase forms many micropore networks, and its absorbability and ion-exchange capacity increase therewith
By force.Microwave radiation is carried out in conjunction with microwave activation simultaneously to be modified to which, makes the montmorillonite in electromagnetic field of high frequency absorb electromagnetism
After ripple, temperature is raised, simultaneously because which is heated evenly, is more conducively dredged the blocking of montmorillonite inter-layer passages and is formed microcellular structure.
So that modified alta-mud has optimal adsorption effect.
Bentonite is in the adsorptivity, thixotropy, cohesiveness, catalysis activity, suspension for after modified, itself possessing
A series of excellent physicochemical properties such as property, plasticity, lubricity, heat stability and cation exchange are all greatly improved, its
Excellent hygro-expansivity, hypotonicity, high adsorption and good self-enclosed performance further improve the combination property of product.
Meerschaum is a kind of fibrous hydrous magnesium silicate, because being associated with attapulgite, montmorillonite, Talcum etc., can be inhaled
Attached formaldehyde, benzene, etc. harmful carcinogen.After modified, its performance is also greatly improved.
The present invention is the technical scheme of the science practicality that inventor summarizes out by long-term practice, with prior art phase
Than, the present invention after to inorganic mineral activation modification, then the proportioning of science is carried out to material, so that the coating of the present invention
With itself enhanced natural bonding force and intensity, metope, plank can be attached to, make the decorative pattern figure of various different colours
Case, can remove the organic volatiles such as formaldehyde, toluene, dimethylbenzene, sulfur dioxide, VOC, with damping, fire protection flame retarding, mould proof anti-
The functions such as tide, purify air.
In sum, instant invention overcomes existing material for air purification purification efficiency is not high, the defect with hazardness is carried
For the coating with air-cleaning function do not contain rubber powder, cement, purification efficiency is high, and nonhazardouss are pollution-free.
