Description

Coating with air-cleaning function
Technical field
The invention belongs to field of environment protection, and in particular to a kind of coating with air-cleaning function.
Background technology
" 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 much studying in terms of air purification, develop various with purification air The material of function, such as Chinese patent CN102584113B are prepared in environmental protection using diatomite, attapulgite, rubber powder raw material Wall coating, but the invention does not carry out necessary modification to diatomite, attapulgite, and rubber powder itself is just with formaldehyde etc. Organic volatile, and more micropore shape features of diatom ooze can also be sealed by colloid and have no way of playing adsorption function, cause to purify It is inefficient.Chinese patent CN105218033A is prepared for the bentonite colour-wash powder with air purification function, the invention Use the materials such as colored portland cement, nano-titanium dioxide, and cement can block the invention completely and rely performance absorption The hole of effect material, evaluated report confirms nano-titanium dioxide with experimental principle at present：" nano-titanium dioxide " is to experiment Animal has carcinogenicity for room, it is possible to causes human carcinogen（Possibility is 2B grades）.
The content of the invention
The purpose of the invention is to overcome existing material for air purification purification efficiency not high, there is the defects of harmfulness, There is provided for people a kind of without rubber powder, cement, purification efficiency height, nonhazardous, 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%, diatomite tailing 2% ~ 6%, methyl Cellulose 1% ~ 5%, wood-fibred 0.3% ~ 1%.
In such scheme, the modified alta-mud formaldehyde adsorbent is to heat bentonite in sulfuric acid or hydrochloric acid, then is passed through Microwave radiation and obtain.
In such scheme, it by bentonite and sodium carbonate or sodium fluoride is 24 in mass ratio that the modified alta-mud, which is,:1 is mixed Reaction 7 days is closed, dry, pulverize to 320 mesh and obtain at 80 ~ 100 DEG C.
In such scheme, the modified meerschaum is to crush sepiolite, acidified processing, then at 200 ~ 300 DEG C Roast and obtain.
The coating with air-cleaning function of the present invention, its preparation method are：
Weighed by formula, during modified alta-mud formaldehyde adsorbent, modified alta-mud, kaolin are launched into mixer fully Stirring 5 minutes, then by modified meerschaum, nano silver-carrying antiseptic, titanium dioxide, calcium carbonate, diatomite tailing, methylcellulose, Wood-fibred is launched into mixer and is uniformly mixed stirring 10 minutes jointly, obtains the powdered coating with air-cleaning function.
The coating with air-cleaning function of the present invention, its application method are：
By the coating with air-cleaning function and water in mass ratio 1:1 ratio is uniformly mixed, and is brushed on wall.
The preparation method of modified alta-mud formaldehyde adsorbent used in the present invention presses Chinese patent application 201610244147.4 Operation, by montmorillonite（Bentonite）Activation modification, and belong to layer aluminosilicate for montmorillonite, it 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 Deng cation these notable design features, activation modification is carried out to bentonite, these cations substitute dissolution by hydrogen ion, make it Chemism is produced, while makes a pair of of aluminium ion in montmorillonite octahedral structure and two pairs of hydroxy dissolutions in montmorillonite Crystal layer spacing increase, specific surface area increase, form more micropore networks, its adsorption capacity and ion-exchange capacity increase therewith By force.Microwave radiation modification is carried out to it in conjunction with microwave activation at the same time, the montmorillonite in electromagnetic field of high frequency is being absorbed electromagnetism Temperature raises after ripple, simultaneously because it is heated evenly, more conducively dredges the blocking of montmorillonite inter-layer passages and forms microcellular structure. So that modified alta-mud has optimal adsorption effect.
Bentonite after modified, itself possess adsorptivity, thixotropy, cohesiveness, catalytic activity, suspension A series of excellent physicochemical properties such as property, plasticity, lubricity, heat endurance and cation exchange are all greatly improved, its Excellent hygro-expansivity, hypotonicity, high adsorption and good self-enclosed performance further improves the comprehensive performance of product.
Sepiolite 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 modification, its performance is also greatly improved.
The present invention be inventor by long-term practice sum up come science practicality technical solution, with prior art phase Than the present invention is by the proportioning to inorganic mineral activation modification and then to material progress science, so that the coating of the present invention Natural bonding force and intensity with itself enhancing, can be attached to metope, plank, make the decorative pattern figure of various different colours Case, can remove the organic volatiles such as formaldehyde, toluene, dimethylbenzene, sulfur dioxide, VOC, have damping, fire protection flame retarding, mould proof anti- The functions such as tide, purification air.
In conclusion the present invention overcomes existing material for air purification purification efficiency is not high, there is the defects of harmfulness, carry The coating with air-cleaning function supplied is without rubber powder, cement, and purification efficiency is high, and nonhazardous is pollution-free.
