Description

The anti-scribble interiro wall latex paint of the clean taste of a kind of nanometer

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; the anti-scribble interiro wall latex paint of the clean taste of nanometer that has low VOC content, high water-fast, alkaline-resisting, scrubbing resistance and can purify air, belongs 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 research and develop a kind of can either resolving harmful gas, 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 interiro wall latex paint of the clean taste of a kind of nanometer, this product not only has water-fast, alkaline-resisting, the scrub performance of low VOC content, superelevation, can purify air, effectively decompose formaldehyde free in air, benzene class objectionable impurities; And paint film is fine and close, have certain hydrophobic function.

Concrete component and the part by weight of the anti-scribble interiro wall latex paint of the clean taste of a kind of nanometer of the present invention are: water: 15-25%; Wetting agent: 0.1-0.2%; Dispersion agent: 0.4-0.8%; Defoamer: 0.3-0.8%; Anatase thpe white powder: 10-15%; Talcum powder: 5-8%; Water-ground limestone: 8-10%; Fine particle calcium carbonate: 10-12%; Water-washed kaoline 5-8%; Pure aluminium silicate 1-2%; Nanometer air cleanser: 0.1-0.2; Organosilicon lotus property emulsion 5-10%%; Low smell material: 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 used a kind of nanometer air cleanser, can effectively decompose the objectionable impuritiess such as formaldehyde free in air, benzene class, has the function purifying air.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 low smell material that the present invention uses be a kind of by n-butyl acrylate and methyl acrylate by the core-shell copolymerized tiny latex of a kind of aqueous dispersion forming, viscosity is low, odorlessness, not containing ammoniacal liquor and the agent of any solvent post-plasticization, have outstanding color stuffing consistency and viscosifying power, in the middle of formula, do not need to add any film coalescence aid, greatly reduce the organic volatile content in this coating products.And there is good water tolerance and resistant to hydrolysis performance.

The nano functional air cleanser that the present invention uses, is to be major ingredient by self charged natural materials, the pure natural multifunctional passive anion-generating material of producing through scientific matching.This material can forever discharge the negative ion useful to HUMAN HEALTH under passive states, produces the far infrared rays useful to human body, has obvious bacteriostasis antibiosis effect.After this product is added to interior wall latex and wherein brushes, can effectively dispel at short notice the obnoxious flavoures such as the formaldehyde that discharges in home decoration material, furniture, benzene class, amine.It is a kind of multi-functional, high performance material for air purification.

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.Because titanium dioxide produces high energy consumption in process of production, in this product, reduce by 20% titanium dioxide consumption, in the situation that quality product is constant, indirectly reach the object of low-carbon (LC), reduction of discharging.

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, fine particle calcium carbonate, talcum powder, water-washed kaoline, after high speed dispersion, be ground to after slurry fineness≤30um, stirring at low speed adds nanometer air cleanser, organosilicon lotus property emulsion, the solid low smell material of power of peace, 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.

Below embodiment, be one embodiment of the present of invention.
