Description

Technical Field

[0001] The present invention relates to the technical field of artificial stones, and in particular to a method and equipment for manufacturing textured paving stones by utilizing marble waste. Background Art

[0002] Artificial stone is made from crushed natural stone aggregate, combined with binders and pigments. Traditional artificial stone manufacturing technology is relatively mature and widely used in construction, decoration, and other fields. The method of using marble waste to create textured paving stones not only recycles marble waste, reducing resource waste and environmental pollution, but also provides a new source of raw materials for artificial stone manufacturing. Furthermore, the textured paving stones produced by this method are aesthetically pleasing and durable, meeting the decorative needs of various occasions.

[0003] Application No. 200510100876.4 discloses a method for manufacturing colored artificial marble, including batching, molding, and curing. Stone powder and resin are mixed in a blender, and a base pigment is added to form a base color powder, which is then injected into a mold. A separate portion of the powder is mixed with a reinforcement pigment to form a reinforcement color slurry. This slurry is then sprayed into the base color powder in the mold using compressed air at a rate of 20-25 kgs / cm². After vacuuming, a vibrating indenter at a frequency of 3,500-4,000 times / minute compresses the powder surface at a pressure of 0.8-1 MPa for 5-10 minutes. After the resin cures, the material is removed from the mold and allowed to stand for 3-7 days until fully cured. This method requires simple equipment and is easy to implement. The resulting product exhibits a natural texture and grain, with consistent texture throughout the entire surface. Color can be adjusted as needed. This method is suitable for small and medium-sized stone mills to utilize waste materials to produce high-quality and affordable artificial marble.

[0004] In the production process of textured paving stones, glazing devices or simple mechanical vibrations are usually relied upon to arrange particles to simulate the texture of marble. The texture of marble simulated by glazing devices lacks texture layering, and the degree of simulation of marble texture simulated by mechanical vibration is relatively low. Some processes may require the use of chemical adhesives to enhance the bonding strength between the particles and the brick embryo, which not only increases production costs but may also cause environmental pollution. Summary of the Invention

[0005] The object of the present invention is to provide a method and apparatus for manufacturing textured paving stones using marble waste, so as to solve the problems raised in the above-mentioned background technology.

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0050] In this application, for ease of understanding, the method steps used do not need to be executed in the order of the steps in this embodiment during actual operation. In other embodiments, these steps may be performed simultaneously or in a different order.

[0051] like Figures 1-6 As shown, the present invention provides a technical solution: a method for manufacturing textured paving stones using marble waste, the method comprising:

[0052] Raw material collection: collecting scraps, broken materials and other waste materials generated during marble processing, as well as raw materials for brick production, to reduce production costs and achieve resource reuse;

[0053] It should be noted that by collecting scraps, crushed materials and other waste materials generated during the marble processing process, not only the production cost is reduced, but also the resource reuse is achieved, which is in line with the concept of sustainable development;

[0054] Marble waste classification, sorting marble waste based on color;

[0055] It is important to note that sorting marble waste based on color helps to create rich textures and color effects in the subsequent manufacturing process, improving the aesthetics and artistic value of the paving stones.

[0056] Crushing and screening: crushing the classified marble waste into particles, screening the crushed particles to obtain marble aggregates of different particle sizes;

[0057] It is important to ensure the uniformity and applicability of the aggregate, which provides a good foundation for subsequent raw material proportioning and pressing;

[0058] Raw material proportioning: mixing different types of raw materials in proportion, usually using continuous grading or discontinuous grading, to ensure the density and strength of the aggregate and improve the overall performance of the paving stone;

[0059] It is important to ensure the density and strength of the aggregate, which improves the overall performance of the paving stone and makes it have better compression resistance, flexural resistance and wear resistance;

[0060] Stirring and mixing, mixing the raw materials, cementing materials, additives and appropriate amount of water in proportion to form a uniform mixture, ensuring that the components are evenly distributed to avoid local strength deficiency or defects;

[0061] It should be noted that it can ensure the uniform distribution of various components, avoid the occurrence of local strength deficiency or defects, and improve the quality and stability of the paving stones;

[0062] Pressing and molding: pouring the mixed material into a mold and pressing it to form a paving stone body of the desired shape and size;

[0063] Secondary paving: laying the marble waste particles on the paving stone blank. The specific steps are as follows:

[0064] S1: Pretreatment, roughening the surface of the paving stone;

[0065] S2: dynamic mixing of marble waste particles;

[0066] S3: dynamic paving of marble waste particles;

[0067] Pressing and embedding: pressing the paving stone body, pressing and embedding the marble waste particles into the paving stone body;

[0068] It is important to note that this ensures a close bond between the waste particles and the green body, improving the overall strength and durability of the paving stone.

[0069] Brick sintering: sintering the paving stone blank at high temperature to form a strong chemical bond between the particles, thereby improving the strength, hardness and wear resistance of the paving stone;

[0070] It is important to note that the strength, hardness and wear resistance of paving stones have been significantly improved, making them more suitable for outdoor environments;

[0071] Demolding and curing: demoulding the paving stones. The demoulding bricks are placed in a suitable environment to keep them moisturized, so as to stabilize the structure, release stress and increase strength, and prevent cracking and deformation in the later stage.

[0072] It should be noted that it helps to stabilize the structure of the paving stones, release stress and increase strength, and prevent later cracking and deformation. At the same time, the maintenance process can also improve the freeze-thaw resistance and durability of the paving stones.

[0073] The pretreatment steps of the paving stone blank are as follows:

[0074] L1: Clean the surface of the paving stone;

[0075] It is important to clean and remove impurities on the surface of the paving stone.

[0076] L2: Surface treatment, mechanically scoring the surface of the paving stone embryo to achieve the required roughness;

[0077] It should be noted that the surface of the paving stone embryo is mechanically scored to control the roughness within Ra 6.3-10.0μm and Rz 40-80μm (maximum peak-to-valley height difference). Ra 6.3-10.0μm is suitable for outdoor scenes (anti-slip coefficient ≥ 0.6, particle interlocking density reaches 1.8-2.2g / cm³), Rz 40-60μm can ensure that the epoxy glue or cement mortar completely penetrates the gaps between particles, and Rz 60-80μm further enhances the mechanical bite force. This parameter combination balances the friction resistance and interlocking depth, thereby increasing the volume filling rate of waste particles by 30%-40%, and at the same time increasing the flexural strength of the finished product to 12-18MPa.

[0078] The marble waste particles dynamic mixing steps are as follows:

[0079] M1: Particle size ratio, mix the marble waste particles according to the particle size;

[0080] It is important to note that the phased progressive mixing strategy ensures that each particle size segment is evenly distributed according to the preset ratio, avoiding the aggregation of large particles or the loss of small particles, forming a stable skeleton-filling structure, and reducing stress concentration caused by uneven particle size.

[0081] M2: Color ratio matching: Based on the target color value and matching ratio, particles of different colors are graded and fed to ensure the accuracy of the color ratio, obtain the target color and texture effect, and ensure that the color of the paving layer is uniform and the transition is natural;

[0082] It is important to note that the color ratio can be precisely controlled by graded feeding to ensure uniform color and natural transition of the paving layer, which can meet diverse design requirements, simulate the texture of natural marble, and enhance the visual appeal of the product.

[0083] Based on the target color value, the color is divided into primary color, secondary color and decorative color, and the proportion is set. The primary color marble waste particles are beige with a proportion of 75%, which plays the role of laying the foundation for the basic color tone. The secondary color marble waste particles are light gray with a proportion of 20% to increase the layering and texture depth. The decorative color marble waste particles are dark brown with a proportion of 5% to simulate the cracks and metallic luster of natural stone.

[0084] M3: Stirring and mixing. By adjusting the stirring intensity and direction, the particles are prompted to continuously roll and collide in the mixed system, completely eliminating stratification and agglomeration.

[0085] It should be noted that the stirring intensity and direction should be adjusted to cause the particles to continuously roll and collide, completely breaking the adhesion between the particles, avoiding stratification or agglomeration, ensuring that particles of various sizes and colors are evenly distributed, and providing a consistent basis for subsequent paving and pressing.

[0086] The dynamic paving steps of the marble waste particles are as follows:

[0087] P1: Preliminary paving: First, large-particle waste is spread according to the preset thickness to form a basic skeleton structure, providing high bearing capacity and permeability;

[0088] It should be noted that large-particle waste forms a high-bearing capacity and permeable base structure, providing stable support for subsequent paving.

[0089] P2: Small particle filling, covering the surface of the large particle layer with small particle waste to fill the gaps and improve the surface smoothness;

[0090] It should be noted that the small particles cover the surface of the large particle layer, fill the gaps, reduce surface undulations, and improve the aesthetics of the pavement. At the same time, the small particle filling layer and the large particle layer form an interlocking structure to improve the overall shear resistance.

[0091] P3: Dynamic speed control: According to the width of the base surface and the particle size distribution, the diameter of the marble waste particles is continuously adjusted during paving, so as to dynamically adjust the total amount of marble waste particles to make the paving stone surface have the properties of marble and simulate the texture and transition effect of natural marble.

[0092] It should be noted that the total amount of paving materials should be dynamically adjusted according to the base width and particle size distribution to form a naturally transitional texture level and enhance the stone imitation effect.

[0093] The pressing and interlocking process imprints the large and small waste particles on the surface of the brick embryo according to a preset trajectory and pressure, so that the particles are further embedded in the surface of the brick embryo to form a highly simulated marble texture. There is no need to use chemical adhesives to enhance the bonding strength between the particles and the brick embryo, thereby reducing pollution to the environment. Example 1:
