Background technology
Building coating such as groups of stars are bright bright, are present in generation with separately self-value.CN1590470A discloses " exterior wall mineral varnish coating and preparation method thereof in a kind of aqueous environment protection " technology, and certain contribution has been made in environmental protection, but this coating texture slightly inferior one, and do not have colorful piebald, do not imitate the aesthetic feeling of many combinations of crag.CN1088855A discloses " constructional method of ornament with compound multi-colour paint " technology of Niu Zhiyong application, this is a kind of interior wall coating, adopts the vinylformic acid interior wall coating, and color sand, plastic cement liquid or its mixture are made coating, the diameter of the color point of ejection is 1-3mm, and the density of spraying two times is 5-7 color point/cm
2, as spray three, four times, then density is bigger.Give a kind of gentle and quiet visual effect, lack the visual effect of the rough grandness of exterior coating crag shape, and in selection, lack water tolerance, aging-resistant explicitly calls for.
Summary of the invention
The present invention is directed to the above-mentioned deficiency of prior art, design a kind of with aqueous putty decide material, have imitative crag characteristic, have rough grand visual effect, water-fast, double layer rock wall imitation external wall paint and coating process thereof that resistance to deterioration is strong.
Purpose of the present invention can realize by following measure: it is made up of following raw materials according and weight part thereof: 10-70 part aqueous adhesive, 1-30 part colorant, 10-60 part stopping composition, 0.2-2 part auxiliary agent, 10-50 part water.The coating process of this double layer rock wall imitation external wall paint is that each operation is carried out in the following order: the cleaning metope, execute that priming paint, line are taped, alms giver's chromatograph, color spray spot, pull except that adhesive tape, dryness finalization, execute finishing paint.
The also available following measure of purpose of the present invention comes perfect: said aqueous adhesive is to select for use in emulsion for building, cement and emulsion mixture, cement and the rubber powder mixture.Said emulsion is that the emulsion of water-intake rate in the acrylic emulsions<15% is preferred, can select for use from benzene emulsion, acetate emulsion in addition; Said rubber powder is a vinyl acetate between to for plastic---select for use in ethylene copolymer (EVA), the poly-tertiary ethylene carbonate multipolymer of vinyl acetate between to for plastic, the modified acroleic acid, especially organic-silicon-modified EVA is preferred.Said colorant is toner material or mill base material, and its color comprises the sensitive various colors of vision: the blue three primary colors of reddish yellow, black, white, colour filter excessively, composite look.Said stopping composition is at least a in inorganic mineral powder, flyash, the lime, and is especially with the mineral material of sheet structure, preferred as mica, kaolin, talcum powder.The granularity of said stopping composition is the 60-3000 order.Said auxiliary agent is biocide mildewcide, dispersion agent, thickening material, defoamer, antiaging agent, defend and split fibre, hydrophobizing agent, especially with at least a in silicone based hydrophobizing agent, the polyoxyethylene wax dispersion.At least spray color spot one time in the said color spray spot operation.The diameter of color spot mostly is centimetre-sized, sprays twice or repeatedly during color spot road color spot under the spray when preceding road institute color spray spot is not dried.
Embodiment
The present invention will now be further detailed embodiment:
Embodiment 1: with 40 parts of (weight parts, ACRYLIC EMULSION down together), 15 parts of water, 3.5 part mill base, 40 parts of granularities are 250 purpose kaolin powders, 1.5 part biocide mildewcide, antiaging agent, hydrophobizing agent and methylcellulose gum are got material ready, special application worker has cleared up metope, execute priming, after line is taped, promptly execute priming paint, each material stirs according to the above ratio, red mill base admix the putty pinkiness that makes as major ingredient, with this chromatograph of deciding, special priming paint refers to touch when doing, the brush or roll on red mass-tone layer, remaining is red, palm fibre, the brown mill base is made into putty and irritates respectively in three spray guns, after spray punctation successively, the brown spot, brown spot.Wherein control area size and rare close degree of each spot well,, pull, after finishing dryness finalization in 24 hours under 25 ℃ of temperature, execute finishing paint again except that adhesive tape to copy the red marble crag in Sichuan.
Embodiment 2: with 30 parts of silicate cements, 2 parts of EVA rubber powders, 35 parts of water, 10 parts of granularities is that 300 purpose quartz, 30 parts of granularities are 300 purpose flyash, 0.3 part of biocide mildewcide, 0.2 part of antiaging agent, 0.5 part of silicone based hydrophobizing agent, 1 part of paper pulp fiber mixing and stirring, 5 parts of black pastes, 5 parts of white slurry are irritated respectively in two spray guns, method as embodiment 1 is coated with that to dress up with gray mortar be that the spray of mass-tone and major ingredient is with the imitative crag metope of the multiple layer of blackspot and hickie.
Embodiment 3: with 40 parts of white cements, 30 parts of benzene emulsions, 25 parts of water, 5 parts of light green mill bases, 30 parts of titanium dioxides, 5 parts of lime, both granularities of back is 3000 orders, 0.2 part thickening material, 0.2 part of antiaging agent, 0.2 part of polyoxyethylene wax dispersion, 1 part of polypropylene fibre are coated with the multiple layer piebald metope of dressing up major ingredient and mass-tone white putty, light green spot as embodiment 1 same operation.
Here it should be noted that: joining putty need now have now during application fully; The selection of various raw materials should consider cost, environmental protection, performance, best arranging effect as a whole, obtain the factor such as difficulty or ease program degree of raw material and decide.
As exterior coating, the total requirement of selection is no matter to select tackiness agent, select stopping composition, select colorant, select auxiliary agent, require anti-aging reaching more than 250 hours, water tolerance is more than 96 hours, photostabilization is greater than 5 grades, it is up to standard entirely that these back three standards are not that each raw material all needs, but with its effect in coating, and this is up to standard essential up to standard.
In coating process, the cleaning metope mainly is to remove the floating sand-lime dirt of metope, whole with the putty equating in case of necessity; Executing priming paint has alkali-resistivity and increases the effect of this coating with body of wall sticking power; Execute finishing paint have water-fast, keep a public place clean, ageing-resistant function.The concrete operations method of each operation colleague technician give directions a little promptly can, carefully do not state with foring this reason, should give what prevent is to serve as reasons with the saving cost, from going to clear up metope less, execute priming paint, executing only being together and changing bad approach the finishing paint three process.
