Description
Technical field
The present invention relates to building coating production field, particularly a kind of dope for inner wall of architecture is produced.
Background technology
Traditional indoor paint only has the function of protection body of wall and decorating wall, there is no too large effect, but indoor decoration inevitably causes gathering of formaldehyde, benzene-like compounds to the Air quality improved in room, and this can cause damage to human body.In addition, the negative ion concentration in the air of Urban areas is significantly lower than the negative ion concentration environment that human normal life's environment needs, and the use of the electrical equipment such as air-conditioning causes indoor negative ion concentration lower, and this is totally unfavorable to the orthobiosis of the mankind.Present people can only alleviate these problems by ventilation of windowing, but limited efficiency.
CN101735700B (2012.12.19) discloses a kind of compound method of indoor paint, and the coating of the method preparation is for improving indoor environment limited use.
Summary of the invention
The object of the invention is to overcome the difficult problem that existing coating can not improve indoor environment, solved the problem by innovation indoor paint compound method.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs:
A kind of dope for inner wall of architecture of health environment-friendly is made up of the component of following weight part: water-based emulsion 30-60 part; titanic oxide nano 20-30 part; film coalescence aid 1-5 part; dispersion agent 0.2-0.8 part, defoamer 0.1-0.2 part, wetting agent 0.1-0.2 part; filler 10-20 part; sorbent material 1-5 part, air microcapsules 5-25 part, vegetable fibre 1-5 part;

(4) under 500-1000r/min condition, in step (3) described mixture, adding sorbent particles with titanic oxide nano mixture, filler, air microcapsules and vegetable fibre mixes;
(5), under being less than the condition of 500r/min, in (4) described mixture, adding water-based emulsion and film coalescence aid and mix.
After house decoration, indoor have the obnoxious flavour such as a large amount of formaldehyde, benzene class, and resident family needs to move in for ventilation 2-4 month after finishing; Due to the use of the electrical equipment such as air-conditioning, in city resident family room, negative ion concentration is extremely low, does not far reach the demand of healthy living.For these problems, contriver wishes that invention a kind ofly can remove indoor harmful gas, improve IAQ (indoor air quality) and the coating of energy-conserving and environment-protective.Contriver selects titanic oxide nano as system component part, photocatalytically titanium dioxide can the obnoxious flavour such as catalysis formaldehyde and benzene class degraded, kill the harmful microorganism that is attached to surface of wall and indoor negative ion concentration can be increased, thus effectively improve IAQ (indoor air quality); Meanwhile, contriver selects sorbent material can adsorbing indoor harmful gases as coating composition, can also increase the concentration of obnoxious flavour around titanic oxide nano, the degradation speed of enhancing; For strengthening the heat preservation and soundproof effect in room, contriver has selected air microcapsules as coating composition, and this contributes to the use reducing room conditioning, increases indoor negative ion concentration.
As preferably, described water-based emulsion is aqueous acrylic emulsion or polyaminoester emulsion.
As preferably, described film coalescence aid is propylene glycol or ethylene glycol phenyl ether.
As preferably, described sorbent material is one or more in gac, diatomite and zeolite powder.Add adsorbent elements in coating and effectively can reduce indoor harmful gas concentration.
As preferably, described sorbent material particle size range is 0.1-10 micron, and size controlling contributes to expanding the surface-area that sorbent material contacts with air within the scope of this, while can ensure again the size in sorbent material internal adsorption aperture.
As preferably, described filler is one or more in talcum powder, wollastonite, water-ground limestone and kaolin.
As preferably, described air microcapsules is formed by chitin, sodium alginate and yeast extract crosslinking reaction, in microcapsule, chitosan dissolves in 55-65 DEG C of acetum, yeast extract distilled water boils sterilization after dissolving and filters, sodium alginate dissolves in 55-65 DEG C of distilled water, forms microcapsule wall material after three kinds of solution mixing.Microcapsule inner chamber is enclosed with air or carbon dioxide.This makes air microcapsules have good heat preservation and soundproof performance.
As preferably, described vegetable fibre is of a size of nano level.
In sum, the present invention has following beneficial effect:
1, the titanic oxide nano that the present invention adds in coating has excellent photocatalysis performance, can decompose the organic volatile being attached to coating surface and also can kill the harmful microorganism such as bacterium, virus being attached to coating surface.
2, in coating, adsorbent elements can a large amount of formaldehyde, benzene class material in absorbed air, effectively improves room air.In addition can be degraded fast and effectively by the titanic oxide nano in coating by the formaldehyde, the benzene class material that adsorb, improve the degradation efficiency of titanic oxide nano.
3, in coating, air microcapsule components has the function of heat preservation and soundproof, can effective lifting section energy efficiency.
4, in coating, plant fiber component has the function of surge chamber humidity.
