Description

The anti-scribble inner wall surface of a kind of white bamboo charcoal purification paint

Technical field the present invention relates to a kind of interior wall coating; be particularly related to a kind of protection for exterior wall surface in buildings and decoration; there is low VOC content, high scrubbing resistance and can purify air, adsorb the anti-scribble inner wall surface paint of obnoxious flavour, anion releasing, belong to chemistry painting industry technical field.

Background technology is in China, and interior wall coating has experienced the development of more than 30 year, has replaced gradually the decorative material for wall surface such as wallpaper, wall cloth, and interior wall coating is more and more applied in the middle of indoor decorating.Therefore also more and more to the functional requirement of interior wall coating, interior wall coating not merely plays the effect of protection, decorating wall, and green, environmental protection, multi-functional interior wall coating are more and more subject to liking of people.But interior wall coating can give out objectionable impurities in production and use procedure, and HUMAN HEALTH is caused to adverse influence, and wherein formaldehyde and benzene class are healthy maximum killers, easily cause respiratory tract system disease and leukemia of children etc.This has just caused people to comprising the concern of decorating and renovating material and the worry of its safety performance of coating.Along with enhancing and the concern to HUMAN HEALTH of people's environmental consciousness, desired interior wall coating is not only to rest in the function of protection body of wall, decorated wall surface, the prior feature of environmental protection, health and practicality.Therefore utilize the powerful adsorption function research and development of white bamboo charcoal a kind ofly can either adsorb obnoxious flavour, purify air; Have again certain hydrophobic function, can form fine and close filming, the practicality interior wall coating that ink that body of wall is infected with, spot etc. can easierly be cleaned out is very significant.

Summary of the invention the object of this invention is to provide the anti-scribble inner wall surface of a kind of white bamboo charcoal purification paint, this product not only has the scrub performance of low VOC content, superelevation, and can purify air, the airborne obnoxious flavour of active adsorption, anion releasing, and paint film fine and close, there is certain hydrophobic function.

Concrete component and the part by weight of the anti-scribble inner wall surface of a kind of white bamboo charcoal purification of the present invention paint are: water: 15-25%; Wetting agent: 0.1-0.2%; Dispersion agent: 0.4-0.8%; Defoamer: 0.3-0.8%; Water-ground limestone: 5-8%; Anatase thpe white powder: 15-20%; White bamboo charcoal powder: 10-20%; Fine particle calcium carbonate: 5-8%; Water-washed kaoline: 3-5%; Pure aluminium silicate: 1-2%; Organosilicon lotus property emulsion: 5-10%; Emulsion: 15-20%; Flow agent: 0.1-0.2%; Sanitas: 0.1-0.2%; Thickening material: 0.6-0.9%.

In general, interior wall coating all likely produces objectionable impurities in production and use procedure, causes the pollution to environment, affects the mankind's health, especially the total organic volatile content in interior wall coating, usually said VOC content directly works the mischief to environment, HUMAN HEALTH.The present invention has utilized the powerful adsorption function of white bamboo charcoal, and effectively the objectionable impurities such as free formaldehyde, benzene class in adsorption-decomposition function air, has the function purifying air, and can anion releasing.Meanwhile, the use of organosilicon lotus property emulsion, makes product have extremely low surface tension, has good hydrophobic effect, can form fine and close paint film, easierly wipes out ink, the spot that metope is infected with.

The organic siloxane modified polymerized emulsion that the emulsion that the present invention uses is novel special construction, in drying and forming-film wherein between Si-OH and and base material on-there is multiple cross-linked chemical reaction in OH-, can make coating have extremely low surface tension, can keep splendid hydrophobic effect, stain resistant performance is good, and there are good Compositional type, stable performance with other emulsions.

The synthetic latex RS-998A that the present invention uses is a kind of polymkeric substance being produced by vinylbenzene and acrylic ester copolymer; have that particle is tiny, the feature of modest viscosity; there is high color stuffing supporting capacity; there is good consistency with numerous color stuffings; not containing protective colloid; low VOC content, and make product there is good scrub resistance, water tolerance and alkali resistance.

The anatase thpe white powder that the titanium dioxide that the present invention uses is made for chlorination process, is characterized in having good light scattering ability, and whiteness is good, tinting strength is high, strong covering power, there is higher chemical stability and good weather resistance simultaneously, nonpoisonous and tasteless, non-stimulated to human body.Its performance and opacifying power, weathering resistance and the chalking resistance close relation of filming.

The bamboo charcoal that the present invention uses is a kind of natural bamboo charcoal factor, is to fire and form for a long time under 800 degree high temperature with 5 years above mao bamboons of growth, and outward appearance is glittering silver color.The bamboo charcoal of approximately 1 gram of size as little finger, its surface-area can reach 700 square metres, in air, the obnoxious flavour such as free formaldehyde, benzene class, amine is adsorbed and decomposes, reach the object purifying air, and the atomic structure due to bamboo charcoal self, make it there is excellent oxidation-resistance, can releasing far infrared and negative ion, be a kind of multi-functional filler of rare pure natural.

The dispersion agent that the present invention uses is low-molecular-weight polypropylene amine acid salt dispersion agent, can significantly improve concentration and the stability thereof of color stuffing dispersion pulp, by this dispersion agent, can surround a layer charge at color stuffing particle surface, make repulsion mutually between particle, thereby reach the effect of stable slurry.

The flow agent that the present invention uses is modified polyurethane rheology modifier, it not only has outstanding shear viscosity thickening effectiveness, and its thickened systems has excellent mobility and levelling property, can make paint film in dry process, form film forming thickness and the paint film fullness ratio of uniformity, make paint film present the silks and satins texture that silk is sliding.

Thickening material used in the present invention mainly contains newton-type nonionic polyoxyalkylene class rheology modifier and alkali swelling class thickening material.

Production technique of the present invention is mixed the component of above-mentioned weight ratio at normal temperatures, under stirring at low speed, add part water, wetting agent, dispersion agent, early stage defoamer, coarse whiting, titanium dioxide, white bamboo charcoal powder, fine particle calcium carbonate, water-washed kaoline, pure aluminium silicate, after high speed dispersion, be ground to after slurry fineness≤30um, stirring at low speed adds organosilicon lotus property emulsion, emulsion, later stage defoamer, flow agent, sanitas, thickening material, excess water, meet the requirements of after viscosity, stirring at low speed 10min again, then through checking, filter, weigh packing.
