Background technology
Diatom ooze is a kind of indoor wall finishing material, and it has functions such as removing formaldehyde adjustment humidity absorbing sound and lowering noise.
Existing diatom ooze is main component by diatomite, utilize the obnoxious flavour that diatomite porous structure is come in absorbed air, adding photocatalyst utilizes the photocatalysis of photocatalyst to decompose the objectionable impuritiess such as formaldehyde in air, utilize the advantages such as the water-fast of sierozem power and fungus and mildew resistance to come as subsidiary material, carry out wall on adhesives at interpolation white cement as gelling material.
The technical disadvantages of existing diatom ooze is, diatom ooze main raw material is white calcined diatomite, diatomite itself is faint yellow, only in the process of calcining, add that salt and alkali just can make diatomite become white powder, so alkalescence is very high, following process becomes also will to add when diatom ooze inorganic toner to meet on market client to the demand of shades of colour, although color is many, but production cost is high, complex production process, color is nature not, upper wall has luminosity, and inorganic toner has generation caking in a humidity environment, cause material has toner particle after wall, the metope made grows dim, affect attractive in appearance.White cement and sierozem power can make diatom ooze alkalescence larger in diatom ooze, have the problem of minimal irritation skin.
Summary of the invention
The object of this invention is to provide a kind of for children room wall decoration without dyestuff diatomite functional type wall material.
The present invention adopts following technical scheme:
Of the present invention is be made up of the raw material of following weight part for children room wall decoration without dyestuff diatomite functional type wall material: diatomite 100-500 part, photocatalyst 100-300 part, natural gesso 100-200 part, ripe rubber powder 50-200 part, natural talcum powder 50-200 part, nanometer negative-oxygen ion powder 50-150 part, nano antibacterial, moldproof powder 10-100 part.
Preferred: wall material of the present invention is made up of the raw material of following weight part: 300 parts, diatomite, photocatalyst 200 parts, natural gesso 150 parts, ripe rubber powder 100 parts, 100 parts, natural talcum powder, 100 parts, nanometer negative-oxygen ion powder, 50 parts, nano antibacterial, moldproof powder.
Described diatomite is weakly alkaline helpless worry agent calcining food grade kieselguhr, is commercially available food grade kieselguhr flocculating aids, for filtrations such as beer, High Grade Liquor, quality drinks, Medical blood plasmas.
Weakly alkaline helpless worry agent calcining food grade kieselguhr is weakly alkaline, not skin irritation, vision protection, helpless worry agent calcining food grade kieselguhr is used to also retains diatomite original faint yellow, need not follow-up interpolation toner, solve follow-up interpolation toner cost high, the problems such as complex production process, this soil or food grade kieselguhr, health is environmental protection again, product becomes natural faint yellow, also there is the adsorption function of diatomite itself simultaneously, make this material be applicable to very much infant room to use, color is yellowish does not naturally stimulate eyes, weak base is skin irritation not, food grade materials health environment-friendly, be not afraid of children to contact with 0 distance of metope.
The present invention utilizes the photocatalysis of photocatalyst to carry out the obnoxious flavoures such as decomposing formaldehyde.
Natural gesso is wall on subsidiary material, plays the effect that environmental protection has again wall on matrix material.
Ripe rubber powder is potato extract, natural environmental-protective material, wall effect on matrix material.
Natural calculus-dissolving powder can make wall on material smoothly submissive, and construction is smooth.
Nanometer negative-oxygen ion powder can make material after upper wall, have the function of releasing negative oxygen ion.
The present invention uses nano antibacterial, moldproof powder to replace sierozem power and plays antibacterial and mouldproof effect.
Positively effect of the present invention is as follows:
Solving existing diatom ooze without dyestuff diatomite functional type wall material and add inorganic toner for children room wall decoration of the present invention, cost is high, complex production process, color is nature not, upper wall has luminosity, has toner particle and the problem, formula technique optimization such as disperse not open when construction, make material environment friendly performance higher, weakly alkaline material not skin irritation.
Having the following advantages without dyestuff diatomite functional type wall material for children room wall decoration of the present invention:
1 problem solving diatom ooze highly basic, non-stimulated to skin.
2 food grade kieselguhr safety and Health, are more suitable for child room application, even if children do not eat can not cause damage to health yet.
The diatomite of 3 helpless worry agent calcinings has natural faint yellow, and without the need in the toning of interpolation toner, while reducing costs, production technique is also simple, and natural yellowish color is applicable to children and is suitable for very much, does not stimulate eyes and skin.
The application of 4 ripe rubber powders, instead of the white cement in original diatom ooze, also has wall cohesive action on material while solving the large problem of material alkalescence.
The application of 5 nano antibacterial, moldproof powder instead of sierozem power, also solves the problem of the large skin irritation of sierozem power alkalescence while energy antibacterial and mouldproof.
The interpolation of 6 natural calculus-dissolving powder is that material has good workability, and upper walling material is smoothly submissive.
7 these materials can keep on functional basis of diatom ooze, material is all natural environmental-protective, cost reduces, production process is simple, color nature, not dazzling, weak base is skin irritation not, be applicable to very much children room metope to use, even if child skin 0 is apart from contacting metope or not eating, also can not cause damage to health.
Embodiment 3
Of the present invention is be made up (Kg) of the raw material of following weight for children room wall decoration without dyestuff diatomite functional type wall material:
Diatomite 300, photocatalyst 200, natural gesso 150, ripe rubber powder 100, natural talcum powder 100, nanometer negative-oxygen ion powder 100, nano antibacterial, moldproof powder 50.
The wall material prepared by embodiment of the present invention 1-3 carries out formaldehyde absorbing test, and result is as shown in table 1:
Table 1
Group |
Formaldehyde absorbing rate (%) |
Embodiment 1 |
85 |
Embodiment 2 |
87 |
Embodiment 3 |
88 |
Commercially available diatom ooze |
68 |
Of the present inventionly as can be seen from Table 1 be greater than 85% for children room wall decoration without dyestuff diatomite functional type wall material formaldehyde absorbing rate, far above commercially available diatomite, the present invention adopts natural weak alkali diatomite, and reasonable formula, makes adsorptivity be 3 times of conventional diatom ooze.
Although illustrate and describe embodiments of the invention, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments without departing from the principles and spirit of the present invention, scope of the present invention is by claims and equivalents thereof.
