The water-based colorful paints of the paint can not dissolve one another, so that the multicolor paint can be sprayed once, and the construction is quick and convenient.

Description

Method for producing water type multicolor paint for water drum

[technical field]

The present invention relates to a kind of coating, is a kind of production method of colorful coating for wall surface of water-in-water type specifically.

[background technology]

China's coating for wall surface in recent years adopts the multicolor finish of oil-in-water-type in a large number, contains organic solvent, and the raw materials cost height has also polluted environment; The coating for wall surface of many parians need carry out multiple gun, repeatedly spraying as CN2005100609580 " a kind of marble imitating construction process with high elasticity coating " respectively by the difference of color, and construction is slow, construction technology is complicated.

[summary of the invention]

At the above-mentioned deficiency of prior art, the purpose of this invention is to provide a kind of without organic solvent, the multicolour also production method of a water type multicolor paint for water drum that need once spray.

Above-mentioned purpose realizes by following measure:

This method for producing water type multicolor paint for water drum comprises the steps:

The preparation of the protection sol solution of (1) 5% concentration: raw material and weight part proportioning are Tai-Ace S 150,0.25-0.5 part trisodium phosphates of 95 parts of water, 5 part of 12 crystal water; by above-mentioned weight part water is added in the agitation vat earlier; add trisodium phosphate again, stir to make and dissolve evenly, slowly add AL again ₂(SO ₄) ₃12H ₂O, control rotating speed 800-1200r/min, high speed dispersion 15-20min makes, and is standby;

(2) preparation of white basis lacquer: raw material and weight part proportioning are 25-35 part water, 0.1-0.3 part is made the silicone oil of defoamer, 5-10 part 600-1000 purpose water-washed kaoline, 25-30 part 600-1000 purpose water-ground limestone, 0.3-0.5 part Natvosol, 0.5-1.0 part is made the ammonium polyacrylate salt of dispersion agent, 0.45-0.75 part alkylphenol polyoxyethylene, 25-35 part elastic pure acrylic acid emulsion, the 5% concentration protection sol solution that 5-10 part is made by step (1), in a mixing bowl, add water earlier by above-mentioned weight part, add Natvosol again, be stirred to molten entirely, add the dispersion agent ammonium polyacrylate salt again, alkylphenol polyoxyethylene, silicone oil, stirring 5min with the 200-400r/min rotating speed makes evenly, adding powder again is water-washed kaoline and water-ground limestone, rotating speed 800-1200r/min high speed dispersion 30min, granularity reaches 30 μ m, add elastic pure acrylic acid emulsion again, rotating speed 200-400r/min stirs 5-10min, add 5% protection sol solution at last, stir, standby;

(3) toning: by design requirements, the white basis that makes with 100 weight part steps (2) coats with lacquer and the collocation of 0.1-1.0 part mill base, stirs, and the colored base paint of furnishing mixes into base paint of all kinds respectively according to the above ratio with different monochromes, mixture colors or polychrome;

(4) colored paint granulation: raw material and weight part proportioning are 5% concentration protection sol solution, the colored base paint of 40-50 part, the pure acrylic acid emulsion of 25-30 part organosilicon inarch, the 1.5-3.0 part ethylene glycol monobutyl ethers that 20-30 part is made by step (1); earlier that the pure acrylic acid emulsion and the ethylene glycol monobutyl ether mixing and stirring of organosilicon inarch is standby; to be sieved in 5% the concentration protection sol solution respectively by the correlated color base paint of design one by one again; the screen cloth eye is selected the 5-20 order for use; the spares that this step is made is sneaked into again, and stirring is cost coating.

The invention has the beneficial effects as follows without organic solvent; raw materials cost is low; negative impact to environment is little; adopt the protection sol solution that the colored base paint particle of different colours is wrapped up respectively; make the pigment can sucking-off in water; immiscible, thus the simple and rapid constructional method that can adopt the multicolor finish single to spray.

[embodiment]

Respectively introduce four embodiment below the present invention respectively set by step.

One is that the sol solution of 5% concentration prepares embodiment, raw material and proportioning weight part tabulation 1:

(table 1)

The 2nd, the preparation embodiment of white basis lacquer; raw material and weight part proportioning thereof are listed in table 2, table 2 and hereinafter all water-washed kaoline to be abbreviated as attach most importance to carbon calcium, Natvosol of kaolin, water-ground limestone be that Mierocrystalline cellulose, ammonium polyacrylate salt are that ammonium salt, alkylphenol polyoxyethylene are that Vinyl Ether, elastic pure acrylic acid emulsion are that emulsion, 5% concentration protection sol solution are protection glue.

(table 2)

The 3rd, the embodiment of colored paint granulation, list in table 3 with raw material and weight part proportioning:

Table 3 and hereinafter abbreviate colored base paint as colored paint, and be example with red, yellow, Lan Sanse abbreviates the pure acrylic acid emulsion of organosilicon scion grafting as organosilicon crylic acid latex, and the title ethylene glycol monobutyl ether is pure butyl ether.

(table 3)

Also it should be noted that toning, also divide four kinds of situations, mix into different colored base paints with monochrome, polychrome or the mixture colors of 0.1,0.3,0.7,1.0 weight parts respectively by the white basis of 100 weight parts lacquer.

Embodiment and corresponding proportioning raw materials value in the existing synopsis 1,2,3 are introduced embodiment.All be described for example by the embodiment 3 in three kinds of tables: the one, preparation protection glue is consulted table 1, with slowly adding 5 parts of AL after 95 parts of water, 0.4 part of trisodium phosphate mixing and stirring ₂(SO ₄) ₃12H ₂O, it is standby to make protection glue in 20 minutes with 800-1200 rev/min of high speed dispersion.The 2nd, preparation white basis lacquer; consult the embodiment 3 in the table 2 again; after being stirred to whole dissolvings with 30 parts of water, 0.4 part of Mierocrystalline cellulose; add 0.8 part of ammonium salt, 0.6 part of Vinyl Ether, 0.2 part of silicone oil again; stir 5min to even with 300 rev/mins of rotating speeds; add 7 parts of kaolin, 28 parts heavy carbon calcium again; with 1000 rev/mins of rotating speed high speed dispersion 30min; granularity reaches 30 μ m; add 30 parts of emulsions again; stir 8min in 400 rev/mins and make evenly, add 8 parts of protection glue at last again, it is standby to make the white basis lacquer after stirring.The 3rd, toning with 100 parts of white basis lacquer and 0.7 part of red slurry or yellow slurry or blue slurry or other monochrome or mix mill base and arrange in pairs or groups and mix thoroughly, is made colored base paint of all kinds.The 4th, table 3 is consulted in the granulation of colored paint, with standby after 30 parts of organosilicon crylic acid latexs and the 2.3 parts of pure butyl ether mixing and stirring.Press the design requirements of collocation of colour again; the colored base paint that selects different colours is as 45 parts, and red, yellow, the blue colored paint that respectively accounts for 15 parts is sieved in 25 parts of protection glue with 5-20 purpose mesh screen; again organosilicon crylic acid latex and the adding of pure butyl ether mixture are stirred, promptly make this coating.Be convenient to sift out the look grain of different-grain diameter with the screen cloth of different meshes.

All the other embodiment 1,2,4 consult all that each corresponding raw material and proportioning number make this coating by embodiment 3 same procedure in the table 1,2,3, and are preferred with embodiment 3.With this coating spray gun of packing into, once spraying can be implemented colorful decoration.
