Compared with the prior art, the invention has the characteristics and beneficial effects that:
(1) the limestone-imitated multicolor paint improves the formulas of the limestone color-wiping paint and the limestone spot material A component, and is added with the permeable hydrophilic emulsion, so that the permeable emulsion has small particle size, extremely low surface tension and excellent wetting and permeating effects. In addition, most of the fine limestone sand-containing intermediate coating is hydrophilic quartz sand, so that the limestone color wiping paint and the limestone spot paint are easier to permeate into the fine limestone sand-containing intermediate coating, and the limestone spot paint, the limestone color wiping paint and the fine limestone sand-containing intermediate coating have good fusion, are integrated and have natural decorative effect. Particularly, in terms of functions, the limestone spot material and the limestone color-wiping paint can be bonded with the fine limestone sand-containing middle painting paint, so that the bonding strength is increased, the transverse adhesive force is increased, and cracking is prevented.
(2) The limestone imitation multicolor paint improves the formula of limestone spot materials, the limestone spot materials comprise a limestone spot material A component, a limestone spot material B component and a limestone spot material C component, and multiple color points can be sprayed at one time in the construction process, so that the working procedures are reduced, and the construction efficiency is improved.
(3) The limestone-imitated multicolor paint comprises a layer of coarse limestone sand-containing intermediate paint and two layers of fine limestone sand-containing intermediate paint, has the effect of inlaying large and small particles, and also has the effects of preventing bottom exposure, being easy to level and preventing cracking. And ammonium salt is used as a dispersing agent in the fine limestone sand-containing painting, so that the paint has super water resistance, and the problem of easy foaming in rainy seasons can be avoided. In addition, the talcum powder is added into the fine limestone sand-containing intermediate coating, so that the smoothness and the grindability are improved, and the labor force is greatly reduced.
(4) The limestone-imitated multicolor paint disclosed by the invention improves the formula of the fine limestone sand-containing intermediate coat paint, and polypropylene short fibers are added into the fine limestone sand-containing intermediate coat paint, so that the moisture in the system is rapidly transmitted to the surface and the interface of the slurry due to the capillary action of a fiber structure, the moisture in the slurry is uniformly distributed, and the skinning and cracking caused by too fast surface drying are obviously reduced. In addition, a slow drying agent is added into the paint containing fine limestone sand, so that the opening time is prolonged, and the surface is not dried too fast to cause cracking.
(5) The limestone-like multicolor paint improves the formula of the limestone matte finish paint, and two emulsions are added into the finish paint, wherein one emulsion is a silicone-acrylic emulsion which is a matte emulsion, has certain hydrophobicity, and has higher glass transition temperature and harder texture. The other is pure acrylic emulsion, because the pure acrylic emulsion has fine and small particle size, and the emulsion ultra-dispersion technology enriches a large amount of functional groups on the surface of emulsion particles of the product through structural design and process control, and assists the molecular weight control technology, thereby improving the dispersion and the wrapping of the emulsion on powder and achieving excellent base material permeability. The emulsion permeates into the loose base material, and the functional groups on the surface of the particles are crosslinked to form a compact layer in the film forming process, so that the emulsion has good flexibility, reinforces the base material and enhances the transverse adhesive force. In addition, the monomers are hydrophilic, and the emulsion can be hydrophilic. Because most of the fine limestone sand-containing intermediate coat is quartz sand which is hydrophilic, and the permeable emulsion has hydrophilicity and super-strong permeability, the pure acrylic permeable emulsion compounded in the limestone matte finish coat can be firstly wetted and spread on the fine limestone sand-containing intermediate coat to play a role in permeating and bonding again, and the emulsion has certain flexibility and is less prone to cracking caused by external influence. Finally, the hydrophobic emulsion in the compound emulsion of the limestone matte finish coat paint floats at the top, has a hydrophobic effect, is hard in texture, has a good water-resistant effect, and has certain strength, and the weather resistance and the stain resistance are obviously improved.

Comparative example 1
Unlike example 1, the pure acrylic emulsion of the limestone color wiping paint was replaced with one of the elastic pure acrylic emulsion (comparative example 1-1) and the modified silicone acrylic emulsion (comparative example 1-2) in this comparative example, and the rest was the same as example 1.
Comparative example 2
The difference from example 1 is that the fine limestone sand-containing intermediate coat paint of this example is the same as example 1 except that polypropylene short fibers are not added.
Comparative example 3
The difference from the example 1 is that the fine limestone sand-containing intermediate coat paint of the example is not added with a slow drying agent, and the rest is the same as the example 1.
Comparative example 4
Unlike example 1, the limestone matte finish of this example was identical to example 1 except that no clear acrylic emulsion was added.
TABLE 8 Performance test results for each pair of wall surfaces finished with proportional construction
In comparative example 1-1, although the elastic emulsion had a soft texture and a certain flexibility but had no permeability, the emulsion could be merely applied to a fine limestone sand primer to flexibly modify the surface thereof, but the fine limestone sand primer had no toughness inside, so that the fine limestone sand primer still had a slight crack phenomenon after the nail binding. In addition, due to the fact that the elastic emulsion is added, the particle size of the elastic emulsion is large, after the elastic emulsion meets water, water is absorbed easily among particle gaps, the elastic emulsion is hydrophilic, water on the board surface is not easy to remain, and the lotus leaf effect is weakened.
In comparative examples 1-2, not only the emulsion itself was not flexible, but also was not permeable, so that the fine limestone sand-containing intercoat was not assisted in the crack direction by this emulsion, eventually leading to severe cracking.
Comparative example 2 fine limestone sand-containing intermediate coat is not added with polypropylene short fibers, the position with excessively thick batch scraping has no water guide effect of the polypropylene short fibers, so that the internal moisture is not led out to the surface of the product in time, the internal drying is slow, the surface drying is fast, the internal and external contraction forces are unequal, and finally the cracking phenomenon is caused.
Comparative example 3 fine limestone sand-containing medium coat without slow drying agent, the product particles are fine, the batch scraped paint film is thin, the open time is short, and the water loss is too fast, so that the trowel can not reach the leveling of the paint film, and finally the paint film is uneven and easy to crack.
Comparative example 4 no penetrating emulsion was added to the matte finish, the fine limestone sand-containing primer was bonded and drawn together only by the limestone spot material and the limestone wiping paint locally, and it was difficult to ensure that the fine limestone sand-containing primer did not crack. Only partial penetrating emulsion is added into the matte surface, and the fine limestone sand-containing middle paint is subjected to supplementary penetration and bonding, so that the binding of the fine limestone sand-containing middle paint is enough to crack. In addition, as no penetrating emulsion is added, the surface hydrophilicity is reduced, the surface is more hydrophobic, and the lotus leaf effect is improved.
The above embodiments are merely illustrative, and not restrictive, of the scope of the claims, and other alternatives that may occur to those skilled in the art from consideration of the specification should be construed as being within the scope of the claims.
