Description

Technical Field

[0001] This invention relates to the field of chemical technology, and more specifically to an inorganic three-in-one colored sand art coating and its preparation method. Background Technology

[0002] In traditional decoration, floors are mostly tiled or wood-wooden, and walls are painted with latex paint. Baseboards are installed where the floor and walls meet. However, in daily life and maintenance, tiles can crack or become hollow, wood-wooden floors can develop gaps that are easily scratched, latex paint on walls has poor stain resistance and is prone to impacts, and baseboards easily accumulate dust and require frequent cleaning. With the development of science and technology and the socio-economic landscape, the architectural coatings industry is also developing rapidly. Increased environmental awareness and higher demands for decorative properties in coatings have driven its development.

[0003] Among them, colored sand art paint is a new type of material that requires no putty or paint, using natural colored sand as its main component in the form of powdered inorganic dry powder paint. Compared to tiles, wood flooring, and latex paint, its construction process is greatly simplified, saving time and effort. For home decoration, this means that wall treatment can be completed faster, reducing the decoration cycle, while also reducing construction difficulty and costs. Colored sand art paint also has waterproof, mildew-proof, and stain-resistant properties. Stains on the wall surface can be easily washed away with water and are not easily scratched, making daily maintenance extremely simple. These characteristics make colored sand art paint particularly suitable for home decoration, effectively solving the problems of damp walls, mold, and easy scratching. Colored sand art paint also offers a variety of color options to meet the personalized needs of different consumers, making the walls look more beautiful and elegant; moreover, the wall surface after construction has a strong texture and rich expression, which can enhance the overall decoration level and atmosphere. Colored sand art paint is not only highly practical but also extremely beautiful.

[0004] Although colored sand art coatings already exist, how to further improve the performance of colored sand art coatings and produce more simple and convenient multifunctional colored sand coatings to meet market demand remains a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] Based on the above background technology, the technical problem to be solved by the present invention is to provide an inorganic three-in-one colored sand art coating with excellent performance, simple production and convenient construction, and its preparation method.

[0006] To achieve the objectives of this invention, the present invention relates to an inorganic three-in-one colored sand art coating, the coating comprising the following raw materials in parts by weight:

[0007] 8-12 parts by weight of white cement;

[0008] Snowflake white sand 60-75 parts by weight;

[0009] Dispersible latex powder 3-10 parts by weight;

[0010] 10-15 parts by weight of shell powder;

[0011] 0.2-0.5 parts by weight of cellulose;

[0012] 8-20 parts by weight of fired colored sand;

[0013] 0.1-0.3 parts by weight of powdered defoamer;

[0014] Additives: 0.8-2 parts by weight.

[0015] Furthermore, the cellulose is hydroxyethyl cellulose or hydroxypropyl methyl cellulose.

[0016] Furthermore, the particle size of the sintered colored sand is 90–120 mesh; preferably 120 mesh.

[0017] Furthermore, the additives include lubricant magnesium aluminum silicate; waterproofing agent powdered composite silane waterproofing agent; antibacterial agent nano zinc antibacterial powder; and retarder sodium gluconate; which are mixed evenly according to a weight ratio of 2:2:2:0.5 to 1.

[0018] Furthermore, the dispersible latex powder is preferably in the form of 3 parts, 4 parts, 5 parts, 6 parts, or 10 parts, and the additives are preferably in the form of 0.8 parts, 1 part, 1.2 parts, or 2 parts.

[0019] Furthermore, in embodiments of the present invention, the inorganic three-in-one colored sand art coating also includes inorganic pigments.

[0020] White cement, with its high whiteness, bright color, and high strength, plays a reinforcing role in this coating.

[0021] Snowflake white sand is widely used in coatings. When used in this proportion, it can enhance the three-dimensional texture of the coating and reduce the cost of the coating.

[0022] Dispersible latex powder can significantly improve the hardness, tensile strength, water resistance, adhesion and scrub resistance of coatings. It is also the film-forming base material of this coating. Its dosage is related to the performance of this coating. If the dosage is too low, it will affect the strength and bonding performance of the coating. The colored sand art coating prepared under this ratio is not easy to crack.

[0023] Shell powder is made from natural shell powder, which has green and environmentally friendly properties. It can eliminate and reduce the odor of paint. In addition, paint added according to this ratio has a smooth texture and visual effect.

[0024] Cellulose plays a role in thickening, dispersing, emulsifying, binding, and film-forming in this coating.

[0025] Sintered colored sand is a type of colored sand granules that has undergone high-temperature sintering. It features bright colors, wear resistance, and acid and alkali resistance. In this coating, it plays a coloring role and enhances the aesthetics of the coating. Different colors of sintered colored sand can be added according to different decorative requirements.

[0026] Defoamers are mainly used to prevent bubbles from forming during use.

[0027] Among the additives, the lubricant is the main component that enhances the lubrication of the coating, possessing a low friction factor and self-lubricating properties, thus facilitating mixing during production. The waterproofing agent provides waterproofing, seepage prevention, stain resistance, and color retention without altering the original substrate color. Combined with the antibacterial agent nano-zinc antibacterial powder in this proportion, it improves the antibacterial, antifungal, and scrub resistance of the coating. The retarder sodium gluconate increases the plasticity and strength of the coating and has a retarding effect, delaying both the initial and final setting times. Another aspect of this invention relates to a method for preparing the aforementioned inorganic three-in-one colored sand art coating, comprising the following steps:

[0028] All materials are added to a mixing and grinding device in proportion, mixed and screened, and then distributed by a material distributor to obtain inorganic three-in-one colored sand art paint.

[0029] Furthermore, the mixing and grinding device includes a mixer body, with a feed inlet fixedly installed at the top of the mixer body. The mixer body has an internal cavity, inside which a grinding cylinder is rotatably mounted via bearings. Multiple fixed plates are mounted around the outer wall of the grinding cylinder.

Limiting plates are fixedly mounted at both ends of the outer wall of each fixed plate, and a limiting block is fixedly mounted on one end of the inner wall of each limiting plate. The limiting block and the movable plate are positioned to coincide. A liner is fixedly installed inside the cavity. A discharge trough is opened on the inner side wall of the liner, and the opening of the discharge trough is designed with an arc shape. Multiple material distribution rods are fixedly installed horizontally at the bottom of the discharge trough. An arc groove is opened in the middle of the outer side wall of the material distribution rod, and the arc groove corresponds to the inner wall of the liner. A screen is fixedly installed at the bottom of the discharge trough, and the screen is located inside the material distribution rod. A discharge pipe is fixedly installed on the outer side wall of the mixer body, and one end of the discharge pipe extends between the screen and the bottom of the discharge trough. A mixing motor is fixedly installed on the outer side of the mixer body, and a belt assembly is installed between the output shaft of the mixing motor and the middle of the grinding cylinder.

[0030] Preferably, an equipment frame is fixedly installed on the outside of the mixer body, a mixing hopper is fixedly installed at the top inside the equipment frame, a feeding pipe is fixedly installed at the bottom of the mixing hopper, and the bottom of the feeding pipe is located inside the feed inlet.

[0031] Preferably, a material distributor is fixedly installed inside the equipment frame, a conveying pipe is fixedly installed between the input end of the material distributor and the discharge pipe, a material distribution pipe is fixedly installed at the output end of the material distributor, and a material pump is fixedly installed in the middle of the conveying pipe.

[0032] Another aspect of this invention relates to a construction method for the aforementioned inorganic three-in-one colored sand art coating. The construction method is as follows: First, remove dust and other adhering substances from the surface to be coated. The moisture content of the wall surface should be less than 10%, and the ambient temperature should be above 3°C. Add water to the coating, the amount of which should be 15-25% of the coating volume. Stir for 5-10 minutes, and it can be sprayed or scraped for use. Unused portions should be sealed and stored.

The limiting block 9 coincides with the position of the movable plate 5. The limiting block 9 is used to limit the rotation range of the movable plate 5, thereby limiting the movement range of the grinding roller 7.

[0048] The cavity is fixedly installed with a liner 10. The inner side wall of the liner 10 is provided with a discharge trough 11. The opening of the discharge trough 11 is set with an arc structure. Multiple material distribution rods 12 are fixedly installed horizontally at the bottom of the discharge trough 11. The multiple material distribution rods 12 are used to screen large pieces of material to protect the screen 14.

[0049] An arc-shaped groove 13 is provided in the middle of the outer side wall of the material distribution rod 12, and the arc-shaped groove 13 corresponds to the inner wall of the inner lining 10. The arc-shaped groove 13 is provided to reduce the impact of the grinding roller 7 on the material distribution rod 12. A screen 14 is fixedly installed at the bottom of the discharge trough 11, and the screen 14 is located inside the material distribution rod 12. The screen 14 is used to screen the coating.

[0050] A discharge pipe 15 is fixedly installed on the outer wall of the mixer body 1, and one end of the discharge pipe 15 extends between the screen 14 and the bottom of the discharge trough 11.

Correspondingly, the grinding cylinder 3 is provided with a shaft for connecting with the pulley. The above structure and technical solution are conventional means in the field and will not be described in detail here.

[0051] An equipment frame 17 is fixedly installed on the outside of the mixer body 1. A mixing hopper 18 is fixedly installed at the top inside the equipment frame 17. A feeding pipe 19 is fixedly installed at the bottom of the mixing hopper 18, and the bottom of the feeding pipe 19 is located inside the feed inlet 2. The mixing hopper 18 can realize the premixing of coating raw materials.

[0052] A material distributor 20 is fixedly installed inside the equipment frame 17.

The material pump can extract standard-compliant paint through the conveying pipe 21 and the discharge pipe 15 and convey it to the material distributor 20.

[0053] Working principle of this invention:

[0054] When this device is in use, various raw materials for the coating can be pre-added into the mixing hopper 18. The various raw materials are initially mixed in the mixing hopper 18, and then enter the interior of the mixer body 1 through the feeding pipe 19 and the feed inlet 2. At this time, the stirring motor 16 is started. The stirring motor 16 drives the grinding cylinder 3 to rotate through the belt assembly. The grinding cylinder 3 drives the fixed plate 4 to rotate. Multiple sets of fixed plates 4 push the coating raw materials inside the mixer body 1 to move. The various coating raw materials are mixed during the movement. In addition, the fixed plate 4 drives the movable plate 5 to rotate during the rotation. Multiple sets of movable plates 5 are subjected to centrifugal force and swing outward around the pin axis during the rotation. The movable plate 5 drives the extension plate 6 and the grinding roller 7 to swing outward, so that the grinding roller 7 is in contact with the inner wall of the liner 10. At this time, the grinding roller 7 and the liner 10 can achieve the grinding treatment of the coating raw materials.

[0055] During the mixing and grinding process, the coating raw materials circulate inside the liner 10 following the fixed plate 4 and the movable plate 5. When the coating raw materials pass through the arc groove 13, the coating material ground to the specified mesh size can pass through the material distribution rod 12 and the screen 14, which can achieve the screening of coating materials that meet the standards.

[0056] The paint that has passed through the screen 14 can be extracted from the material trough 11 by the material pump, conveying pipe 21 and discharge pipe 15. The paint can enter the distributor 20 through the conveying pipe 21. The distributor 20 can realize the quantitative dispensing of paint and convey the paint to the packaging machine through the dispensing pipe 22 to complete the closed loop of paint production.
