[0019] Other features, objects and advantages of the present invention will become more apparent from the detailed description of non-limiting embodiments made with reference to the following drawings: Figure 1 The present invention is a schematic diagram of a fluorocarbon stone coating after being applied on an exterior wall. DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] The present invention provides a novel fluorocarbon stone coating, which realizes effective cost control and significant performance improvement through the compounding of fluorocarbon, emulsion, additives and natural colored stone in a specific proportion. The coating is particularly suitable for coating the exterior walls of houses, which not only ensures the aesthetics, but also greatly improves the durability and wear resistance of the coating.

[0022] A fluorocarbon stone paint, which is composed of the following components by mass fraction: 6% fluorocarbon (which can be adjusted to 5%-7% according to actual needs), 18% emulsion (which can be adjusted to 15%-20% according to actual needs), 6% additive (which can be adjusted to 4%-8% according to actual needs), and 70% natural colored stone (which can be adjusted to 65%-75% according to actual needs and color requirements).

[0023] Among them, fluorocarbon, as a key ingredient, provides excellent weather resistance and chemically stable adhesive liquid as a binder, ensuring good bonding between the components and adhesion of the coating; additives are used to improve the processing performance and construction properties of the coating, such as leveling and defoaming properties; natural colored stones not only give the coating rich colors and textures, but also enhance the physical strength and wear resistance of the coating.

[0024] Specifically, fluorocarbon is fluorocarbon resin or fluorocarbon emulsion for fluorocarbon coatings, which provides excellent weather resistance and chemical stability, ensuring that the coating is not easily faded or aged when used for a long time in outdoor environments.

[0025] Emulsions are water-based emulsions or oil binders that act as a binder to ensure good bonding between the components and adhesion of the coating, while also improving the construction performance and leveling of the coating.

[0026] Additives include leveling agents, defoamers, thickeners, etc. Leveling agents can be fluorocarbon modified acrylic leveling agents, such as HY-3777, which is suitable for most solvent systems, can greatly reduce surface tension, and level instantly. Defoamers can be wax-containing defoamers, which are suitable for fluorocarbon paints and can effectively eliminate bubbles, or EFKA defoamers can be used, such as EFKA-2010, EFKA-2011, etc. Thickeners should be selected with the same viscosity as fluorocarbon stone coatings, which can adjust the viscosity of the coating to ensure construction controllability and coating quality.

[0027] ‌Leveling agent‌ As an important component of coatings, the main function of leveling agent is to improve the fluidity and wettability of coatings, ensure that the coating can be evenly spread on the surface of the substrate during the coating process, and reduce or eliminate surface defects such as brush marks and orange peel. The addition of leveling agent enables fluorocarbon stone coating to form a smooth and flat coating after drying, greatly improving the appearance texture and decorative effect of the coating; In addition, during the preparation and construction of the coating, a large number of bubbles are often generated due to mechanical effects such as stirring and mixing. If these bubbles are not eliminated in time, they will affect the uniformity and density of the coating. Therefore, defoamers are specially added to fluorocarbon stone coatings, which can effectively destroy the surface tension of bubbles, causing the bubbles to burst and dissipate quickly, thereby ensuring the continuity and bubble-free nature of the coating and improving the construction efficiency and coating quality of the coating.

[0028] In order to meet the requirements of different construction methods and coating thickness, the fluorocarbon stone coating needs to add an appropriate amount of thickener to adjust the viscosity of the coating, making the coating easier to control during application, reducing flow and dripping, and also helping to improve the adhesion and hiding power of the coating. By reasonably adjusting the amount of thickener, the ideal construction viscosity and coating thickness can be obtained, ensuring the excellent performance of the fluorocarbon stone coating on the exterior walls of the house.

[0029] Leveling agents, defoamers and thickeners are important additives in fluorocarbon stone coatings. They work synergistically to not only optimize the construction performance of the coating, but also significantly improve the appearance quality and physical properties of the coating.

[0030] Natural colored stone is a natural stone that has been carefully selected and has rich colors. After being processed by processes such as crushing, cleaning, and drying, it is mixed with fluorocarbon, emulsion, and additives to make coatings. Natural colored stone not only gives the coating rich colors and textures, but also enhances the physical strength and wear resistance of the coating.

[0031] The preparation method of fluorocarbon stone coating comprises the following steps: (1) Colored stone selection and processing As an important component of fluorocarbon stone coatings, the selection of colored stones is directly related to the final visual effect and durability of the coatings. Therefore, in the selection of colored stones, it is necessary to strictly follow the design requirements and consider multiple dimensions such as color, texture, hardness, etc. to ensure that the selected colored stones are not only beautiful, but also harmonious with the architectural style. Generally speaking, high-quality natural colored stones should have the characteristics of bright color, hard texture, and strong wear resistance.

[0032] After the colored stone is selected, a series of processing is required. First, the colored stone is crushed and sieved through sieves of different mesh sizes to obtain particles in the required particle size range. This step is crucial to controlling the fineness and visual effect of the paint. Usually the particle size is controlled between 0.5mm and 2mm, which can not only ensure the uniformity of the paint, but also show the natural beauty of the colored stone. Subsequently, the crushed colored stone is thoroughly cleaned to remove dust and impurities on the surface to ensure the purity of the paint. After cleaning, the colored stone is dried at an appropriate temperature. Generally, an oven or natural drying method is selected to ensure that the surface of the colored stone is completely dry and no moisture remains, laying a good foundation for subsequent mixing and preparation.

[0033] (2) Mixing preparation Mixing preparation is the core link in the preparation process of fluorocarbon stone coating. First, add a predetermined proportion of emulsion into a clean container. The selection of emulsion should be determined according to the performance requirements and construction process of the coating. Generally, an emulsion with excellent weather resistance, adhesion and film-forming properties is selected. When adding the emulsion, stir slowly to prevent a large number of bubbles from being generated due to too fast stirring, which will affect the uniformity and construction quality of the coating.

[0034] Next, add additives accurately according to the ratio. The selection and dosage of additives have an important impact on the performance of the coating. Common additives include leveling agents, defoamers and thickeners, which are used to improve the leveling of the coating, eliminate bubbles and adjust the viscosity. After adding the additives, continue to stir evenly to ensure that the additives are fully dispersed in the emulsion to form a stable system.

[0035] Then, gradually add fluorocarbon resin, which is the key component of fluorocarbon stone coating, with excellent weather resistance, corrosion resistance and self-cleaning properties. When adding fluorocarbon resin, stir while adding until a uniform fluorocarbon emulsion system is formed. This step is crucial to ensure the overall performance and construction quality of the coating.

[0036] Finally, slowly add the dried natural colored stones into the above system and stir at a low speed to avoid the colored stones from breaking and ensure that all ingredients are fully mixed to form a coating with appropriate viscosity. During the stirring process, pay close attention to the viscosity and fluidity of the coating so as to adjust the amount of additives and stirring speed in time.

[0037] (3) Packaging for later use Put the prepared fluorocarbon stone paint into a sealed container. The container should be made of corrosion-resistant and well-sealed materials to prevent the paint from deteriorating due to contact with air. When storing, avoid direct sunlight and high temperature environment, and choose a cool and dry place to ensure the stability and service life of the paint. Before construction, the paint should be fully stirred and checked to ensure that the paint is uniform and free of lumps before construction and use.

[0038] How to use fluorocarbon stone paint: Apply the fluorocarbon stone paint evenly on the exterior wall surface and let it dry naturally.

[0039] Paint application ‌Paint stirring‌: Before construction, fully stir the fluorocarbon stone paint to ensure that the paint is uniform and has no precipitation. When stirring, pay attention to controlling the stirring speed and time to avoid generating a large number of bubbles that affect the coating effect.

[0040] ‌Coating method‌: Apply the stirred fluorocarbon stone paint evenly on the exterior wall surface. During the coating process, care should be taken to control the coating thickness. Generally, a single coating thickness of 0.2mm to 0.3mm is recommended. Too thick a coating is prone to cracking and peeling, while too thin a coating will affect the weather resistance and decorative effect of the coating. Therefore, the coating thickness should be reasonably controlled based on the performance requirements of the coating and construction experience.

[0041] ‌Multi-layer coating‌: When multiple layers of coating are applied as needed, each layer must be completely dried before the previous layer is applied. This step is crucial to ensure the adhesion and film-forming effect of the coating. When applying multiple layers, attention should also be paid to controlling the amount and thickness of each layer of coating to ensure that the coating is uniform, without bubbles or sagging.

[0042] Drying and curing ‌Air Drying‌: Once applied, allow the paint to dry naturally.

[0043] ‌Coating Curing‌: Ensuring that the coating is fully cured is the final step in the application of fluorocarbon stone coatings. During the curing process, the resins and pigments in the coating will further crosslink and fix to form a strong and durable coating. Therefore, before the coating is cured, avoid rubbing, bumping, etc. on the coating to avoid affecting the integrity and aesthetics of the coating.

[0044] In summary, the use of fluorocarbon stone coatings requires strict control of the process parameters and operating requirements of each link to ensure the excellent performance and decorative effect of the coating. During the construction process, close attention should also be paid to the coating effect and coating quality of the coating, and problems should be discovered and handled in a timely manner to ensure the quality and progress of the construction.
