Abstract
The invention relates to building interior wall coating capable of adsorbing indoor harmful gases and purifying indoor air and a preparation method thereof. The coating comprises water, stuffing, adsorbent, emulsion and auxiliary agents. The preparation method comprises the following steps: fully dispersing the stuffing, the adsorbent and a part of auxiliary agents which are well weighed accordingto prescription requirements in water by a high-shear dispersing machine and a basket-type sand mill or other sand mills so as to prepare even slurry, then adding the emulsion and a part of auxiliaryagents into the dispersed slurry, and evenly mixing by a blender in a slow speed to obtain the finished coating product. When the coating is used according to the common coating method of the interior latex coating, the coating has the function of adsorbing toxic and harmful gases, such as formaldehyde, benzene, sulfide gases, other volatile organic matters, and the like indoors after drying.
Description
Technical field
The present invention relates to dope for inner wall of architecture of a kind of energy adsorbing indoor harmful gases and preparation method thereof.
Background technology
For new building thing or newly-decorated buildings, employed material of construction and furniture more or less will give out certain obnoxious flavour, buildings in the use, also can be former thereby constantly produce obnoxious flavour owing to the refuse exhaust gas discharging of people and animal and other.These obnoxious flavour main components have: 1. formaldehyde---mainly by the generations such as incomplete combustion of volatilization, household fuel and the tobacco leaf of material of construction, house decorative material and daily necessities.2. ammonia---by finishing material, building structure, as coming out in the body of wall.3. volatile organic gas one is from little, the low-boiling organic compound of fusing point, as sharp paint, coating, sizing agent, and ground, decorative material for wall surface etc.4. ozone---because generations such as uviolizing, electrical equipment uses.5. carbonic acid gas---human body is breathed out and the waste gas of fuel combustion.These obnoxious flavoures have become the biggest factor of harm public health.
Manage to remove or reduce indoor harmful gas, significant to improving the health of people level.People generally take two kinds of ways to reduce indoor harmful gas, and the one, can utilize natural ventilation or power ventilation to improve outside the Air quality, another then is to use the material of indoor purifying air.These material for air purification often exist with forms such as powder, fibrous, film, particle or blocks, can be divided into by conversion characteristic: 1. physisorption section bar material---as gac, zeolite, other silicate materials.2. chemisorption type scavenging material---having chemisorption or catalyzed reaction is main scavenging material, as being carrier with gac or zeolite, quickens the scavenging material that various chemical reaction substances produce chemical reaction.3. ion-exchange type scavenging material---introduce ion-exchange group in the high molecular polymer, with the ion-exchange purification air, as the ion-exchange on sulphur, the alcohol radical.4. photocatalyst material---glass, pottery etc. as carrier, are added TiO
2Deng photocatalyst material, under UV-irradiation, making water in air branch and oxygen conversion is active oxygen radical, and these favourable free radicals make SO then
2, dusty gas such as NO changes into various harmless mentioning or acids.5. negative ion activated inorganic scavenging material, this class material also has photo-catalysis function except having sorption, decomposition function, all are better than gac in its purification capacity and work-ing life.These materials though have good indoor purifying effect, use inconvenient.The dope for inner wall of architecture of the adsorbable indoor harmful gas that the present invention proposes is a kind of just to have favourable absorption effect and material easy to use.
Summary of the invention
The present invention adopts in preparation inner wall of building latex coating process and introduces a kind of homemade porous adsorbent.This sorbent material forms through special processing with a kind of of multiple porous matter silicate mineralss such as natural diatomaceous earth, attapulgite, vermiculite, perlite, zeolite powder or several.The gained material has abundant micron order hole, given the function of dope for inner wall of architecture adsorbing indoor harmful gases, obnoxious flavoures such as the formaldehyde gas in the adsorbable room air, benzene, ammonia, hydrogen sulfide, coating is originally as the green material that does not contain volatile organic matter.
The invention provides the preparation method of the inner wall of building latex coating of above-mentioned adsorbable indoor harmful gas.
Mainly constituting of dope for inner wall of architecture involved in the present invention by emulsion, filler, auxiliary agent etc.Emulsion is mixed by one or more of acrylic emulsions such as benzene emulsion, pure-acrylic emulsion, organosilicon crylic acid latex, acrylate and vinyl acetate emulsion.Filler is made up of one or more mixing in the raw materials such as kaolin, talcum powder, wollastonite, titanium dioxide, heavy calcium carbonate, sericite.Sorbent material is homemade porous silicate material, in natural silicate mineral zeolite, diatomite, attapulgite, vermiculite, the perlite one or more is handled forming through special boring technique, is rich in a large amount of 0.5～3 μ m micropores.Auxiliary agent is made up of dispersion agent (as 731A, Sodium hexametaphosphate 99), sanitas, film coalescence aid, flow agent, defoamer, thickening material etc.
The weight proportion of this dope for inner wall of architecture is emulsion: filler: sorbent material=100: 35～52: 52.5～67.5.
Its preparation process is to be well dispersed in the water with high-shear dispersion machine and basket type sand mill or other sand mill by the load weighted filler of prescription requirement, sorbent material and part of auxiliary, make uniform slip, again emulsion and part of auxiliary are joined in the dispersive slip, after mixing at a slow speed with stirrer, after the assay was approved, promptly get the coating finished product.
Dope for inner wall of architecture of the present invention has following characteristics: 1. environment protection health, do not contain volatile organic gas, do not contain the heavy metal toxic substance, do not contain any harmful organic substances; 2. have good construction and give birth to energy; 3. coating is stable and intensity is big, and abrasion resistance is greater than 10000 times; 4. through the check of disease prevention and control center, Hunan Province, the coating of this coating has the function of indoor toxic and harmfuls such as stronger absorption indoor formaldehyde, sulfide gas, volatile organic gas, nitride gas.
Embodiment
The preparation process of inner wall of building latex coating is as follows, at 1.5m
3Scuffing of cylinder bore in, add 240 premium on currency, start the high-shear dispersion machine, add the aqueous solution 75kg that contains 2% Natvosol that takes by weighing by the prescription requirement more successively, 731A dispersion agent 3.5kg, Sodium hexametaphosphate 99 3.5kg, kaolin 8kg, talcum powder 16kg, wollastonite 40kg, titanium dioxide 48kg, heavy calcium carbonate 40kg, sorbent material (self-control) 200kg, these material addings finish, after disperseing 0.5～1h, add propylene glycol 20kg, lauryl alcohol ester (TX-12) 12kg, sanitas (KS-2) 1kg, afterwards, grind 1.5～2h with basket type sand mill again, change stirring at low speed afterwards over to, add pure-acrylic emulsion 320kg again, defoamer 1.5kg, ammoniacal liquor 1.7kg, flow agent 2kg, thickening material (TT935) 1.5kg is behind reinforced the finishing, stirring at low speed 2h detects and promptly gets coating of the present invention after qualified.
