Detailed Description

The technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments.

The first embodiment is as follows:

the stone-like paint comprises the following components in percentage by mass: 2% of water, 15% of emulsion, 8% of cellulose, 0.4% of antifreezing agent, 0.05% of defoaming agent, 0.05% of wetting agent, 0.5% of regulator, 4% of thickening agent and 70% of stone powder.

The preparation method of the stone-like paint comprises the following steps:

preparing water, cellulose, an antifreezing agent, a defoaming agent, a wetting agent and a regulator in proportion, and mixing and stirring uniformly; then adding the emulsion and the thickening agent, and further stirring uniformly; and after the mixture is stirred uniformly, adding stone powder into the processed mixed solution for paint mixing to obtain the real stone paint.

Example two:

the stone-like paint comprises the following components in percentage by mass: 2% of water, 12% of emulsion, 10% of cellulose, 0.5% of antifreezing agent, 0.07% of defoaming agent, 0.03% of wetting agent, 0.4% of regulator, 4% of thickening agent, 67% of stone powder and 4% of color piece.

The preparation method of the stone-like paint comprises the following steps:

preparing water, cellulose, an antifreezing agent, a defoaming agent, a wetting agent and a regulator in proportion, and mixing and stirring uniformly; then adding the emulsion and the thickening agent, and further stirring uniformly; after the mixture is stirred evenly, stone powder and color pieces are added into the processed mixed liquid for paint mixing, and the real stone paint can be obtained.

In the embodiment, the cellulose is specifically hydroxyethyl cellulose, transitional scattering of the real stone paint powder can be prevented by adding the hydroxyethyl cellulose, the effective construction area is increased, loss and environmental pollution are reduced, the real stone paint product made of the hydroxyethyl cellulose has a tight structure, the color and luster are uniform and cannot be bloomed during finish paint construction, and the using amount of the finish paint is relatively reduced. After the traditional thickening (such as alkali swelling and the like) is made into the stone-like paint, the structure is relatively loose after the stone-like paint is constructed and molded, the paint consumption is increased when the finish is coated due to the fact that the stone-like paint is thick and thin during construction and different in shape, the absorption difference of the finish is large, the stone-like paint made of hydroxyethyl cellulose is strong in product bonding force and good in emulsion compatibility, and a formed film of the stone-like paint is compact and compact, so that the water resistance of the stone-like paint is improved, the phenomenon of whitening in rainy seasons is effectively prevented, the stone-like paint made of the hydroxyethyl cellulose has a special net-shaped structure, powder sinking can be effectively prevented, the product is stable in the transportation and storage processes, and a good can opening effect is obtained.

The antifreezing agent is propylene glycol, plays a role in water retention and moisture retention in summer and slow drying, enables water to volatilize slowly, plays an antifreezing role in winter, and reduces the freezing temperature of water, and the freeze-thaw stability of the real stone paint is improved by adding 3-4 kg of the antifreezing agent per ton in winter. If the amount of the cellulose in the summer really stone paint formula is larger (for example, 1.5-2 kilograms of the cellulose is added), the propylene glycol can be not added, because the cellulose also has strong water retention and moisture retention effects, and if the amount of the cellulose is less, the propylene glycol needs to be added to prevent too fast drying. The natural stone paint is dried at high temperature in summer, and the problems of film formation on the surface of the emulsion, shade and sun surfaces, temperature difference and color difference and the like can be prevented by slightly drying the natural stone paint

The defoaming agent is composed of organic polyether ester, mineral oil and alcohol in a composite mode, and can be used as a chemical auxiliary agent for defoaming and inhibiting foam in production and application of stone paint.

Wetting agents are agents that reduce the surface tension of the liquid and the interfacial tension between solid and liquid, allowing the liquid to spread easily over the solid surface.

The emulsion is a new generation of stable styrene-acrylic emulsion developed by selecting imported special auxiliary agents and functional monomers, has good water whitening resistance, water resistance and weather resistance, good comprehensive stability, good color development property, toughness and stronger yellowing resistance. It has strong alkali resistance, calcium ion stability, dilution stability and freeze-thaw stability.

The regulator can be selected from ammonia water or AMP-95 which are water-soluble substances, the ammonia water is relatively fast to volatilize, the AMP-95 is completely volatilized for about 1 week, and the AMP-95 is added to have some influence on the initial water resistance of the real stone paint.

The thickener is specifically TRM-380 associated type alkali swelling thickener, which can provide double high thickening efficiency of association thickening and water phase thickening, rapid and excellent thickening efficiency of medium shear (KU) viscosity and low shear viscosity (Brookfield), extremely high pseudoplastic rheological characteristic and excellent anti-sagging and anti-settling performance.

The stone powder is sand grains which are processed by a plurality of procedures of selection, crushing, grading, packaging and the like of marble or granite and the like, has various colors, is prepared by selection and processing, has natural color, does not contain any dye, and has the advantages of no toxicity, no odor, no pollution, corrosion resistance, acid and alkali resistance, insolation resistance and no color change.

The color piece can be added for adding colors to the stone paint and decorating, and different colors can be selected according to personal preference of consumers.

The real mineral varnish that finishes of modulation can use on many basal planes, for example cement brick wall, foam, gypsum board or glass, belong to the aqueous emulsion of a very environmental protection, can not produce any injury to the human body, the life-span of use is longer, if good maintenance, can use 15 years's time at least, factor of safety is very high, as long as can be under construction according to normal construction process, the condition that wholly drops can not appear in the later stage, and 90% filth are difficult to adhere to, the back is washed to the rainwater, it is bright as new, the manual cleaning is easier.

When the real stone paint is prepared, the construction temperature must be ensured not to be lower than 5 ℃ during construction, and if the temperature is too low, the real stone paint is solidified. Secondly be exactly the wall of guaranteeing the construction very dry, if the wall has water, the phenomenon that later stage can appear droing or whitely flower. In addition, the real stone paint can not be stirred too hard, if the real stone paint is stirred too hard, particles of the real stone paint can be ground, and water can not be added into the real stone paint to dilute the real stone paint.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
