Description
Technical field the present invention relates to a kind of coating, and particularly a kind of protection for exterior wall surface in buildings and decoration have the nano modification elastic napping coating of stronger texture decoration functions, high dirt resistance performance, belong to chemistry painting industry technical field.
Background technology in building external paint, elastic coating due to its have elastic stretching good, can effectively hide the crackle of body of wall, thereby become gradually the leading material in decoration of exterior wall.In elastic coating, elastic napping coating has concavo-convex texture and texture, can repair body of wall crackle, and finishing effect is outstanding, and stereoscopic sensation is strong, thereby has been subject to liking of people.Although the sense of elastic napping coating stereo decoration is strong, can form strong visual effect, its stain resistant performance is poor.Especially in environmental pollution day by day serious today, dust and suspended matter in atmosphere are more, and concavo-convex texture more becomes easily infected by pollutent and affects the decorative effect of body of wall.Therefore the contamination resistance that improves elastic napping coating has become our urgent problem.
Summary of the invention the object of this invention is to provide a kind of nano modification high dirt resistance elastic napping coating, and this elastic napping coating not only has stronger texture, also has good weathering resistance, water tolerance, alkali resistance, and stain resistant performance is good.
Concrete component and the part by weight of a kind of nano modification high dirt resistance elastic napping coating of the present invention are: water: 5-8%; Wetting agent: 0.1-0.2%; Dispersion agent: 0.4-0.8%; Propylene glycol: 1-2%; Defoamer: 0.1-0.3%; Titanium dioxide: 1-2%; Coarse whiting: 30-40%; Process white: 3-8%; Wollastonite 3-8%: pure-acrylic emulsion: 1-5%; Elastic emulsion: 32-38%; Texanol:0.5-1%; Nano modification stain resistant auxiliary agent: 0.5-1%; Sterilant 0.1-0.2%; Sanitas: 0.1-0.2%; Thickening material: 0.6-0.9%.
Because elastic napping coating is to use the constructional method of the plucking of filming to obtain a kind of ups and downs appearance of film, the dope viscosity in the time of therefore need to constructing is higher.Therefore need coating to have higher thixotropic viscosity, under high shear forces, dope viscosity is lower, and viscosity is higher under low shearing action, mobility a little less than.Therefore we have used cross-linked type macromolecule emulsion thickened systems and the alkali swelling thickening compound system that contains acidic-group in product, make product have good working viscosity.Simultaneously adding of nano modification stain resistant auxiliary agent, make product there is good weathering resistance and contamination resistance.
The emulsion that the present invention uses is the aqueous dispersion of a kind of n-butyl acrylate and styrol copolymer, is a kind of medium-viscosity, water-based latex that particle diameter is tiny, has the consistency cohesive force of excellent color stuffing, can form elastic, glossy and film, and water tolerance is strong.
The emulsion that the present invention uses is a kind of 100% elastic pure acrylic acid emulsion, at room temperature can produce self-crosslinking, has good elasticity, and normal temperature is difficult for after-tacking; Not containing protective colloid, without film coalescence aid, low VOV content, environmental protection; And have good consistency with numerous color stuffings, make product have good elasticity, scrub resistance, water tolerance and alkali resistance, sticking power is good.
The dispersion agent that the present invention uses makes the anion surfactant of polycarboxylate type, has remarkable moisture dispersibility energy, and foaminess ground can effectively improve the mobility of coating, has the excellent properties of stable slurry viscosity.
The stain resistant auxiliary agent that the present invention uses is for nano modification stain resistant auxiliary agent, and in coating film process, nanoparticle plays hinge point effect, and the organic polymer hinge of line style is reticulated to structure, improves film coated surface hardness; The pore dimension of filming by reduction, improves smooth coating degree; By the reduction static charge of filming, reduce the absorption of atmospheric dust; Making to film possesses good self-cleaning, has improved the stain resistant performance of coating.
The defoamer that the present invention uses is a kind of special nonionic silicon compound, possesses excellent froth breaking ability, and froth breaking ability is stable, can prevent that this product from foaming in construction process again, can obtain not having the ideal of residual bubble to film.
The thickening material that the present invention uses is alkali swelling property and the composite thickened systems of the cross-linked type macromolecule emulsion thickening that contains acidic-group.This thickened systems can effectively improve low-shear viscosity, makes coating have higher accelerating ability, has excellent texture retentivity, fabulous anti-sag performance, and can reduce preferably and roll splashing property.
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, titanium dioxide, process white, coarse whiting, wollastonite, after high speed dispersion, be ground to after slurry fineness≤100um, stirring at low speed adds emulsion, Texanol, nano modification stain resistant auxiliary agent, later stage defoamer, 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.
Composition (weight percent) and the production technique of a kind of nano modification high dirt resistance elastic napping coating of the present invention are: the stirring at low speed stage adds the deionized water of 5.7 parts according to order, the wetting agent X405 of 0.1 part, 0.5 part of polycarboxylate salt dispersant 5040, the defoamer B-199 of 0.2 part, 2 parts of Rutile type Titanium Dioxides 237, 6 parts of fineness are 325 object process whites, the fineness of 36 parts is 400 object water-ground limestones, 6 parts of fineness 800 object wollastonites, after all adding, enter the high-speed stirring stage, after stirring, speed lapping is to fineness≤100um, then under stirring at low speed, add successively the pure-acrylic emulsion 296DS of 5 parts, 36 parts of elastic emulsions 3131, the Texanol of 0.5 part, 0.8 part of nano modification stain resistant auxiliary agent NMI, the defoamer B-199 of 0.25 part, the sanitas MV of 0.15 part, 0.4 part of alkali swelling thickening material H1130, 0.4 part of acidic-group thickening material ASE-60, stirring at low speed 10min again, again through check, filter, the packing of weighing.
