Description

Technical Field

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

[0002] Artificial stone is made of crushed natural stone as aggregate, with binders, pigments, etc. Traditional artificial stone manufacturing technology is relatively mature and widely used in construction, decoration and other fields. The method of using marble waste to make textured paving stones not only realizes the resource utilization of marble waste, reduces resource waste and environmental pollution, but also provides a new source of raw materials for the field of artificial stone manufacturing. At the same time, the textured paving stones manufactured by this method are beautiful and durable, which can meet the decoration needs of different occasions.

[0003] The manufacturing method of colored artificial marble with application number 200510100876.4 includes batching, molding, curing and other processes. Stone powder, resin and the like are placed in a mixer after batching, and basic colorants are added to mix into base color powder, which is then injected into a mold. Another part of the powder is added with colorants for reinforcement to form a reinforcement color slurry, which is placed in a nozzle and sprayed into the base color powder in the mold with (20~25) kgs / cm² of compressed air. After vacuuming, a pressure head vibrates at a frequency of 3500~4000 times / minute, and compresses the powder surface at a pressure of (0.8Mpa~1Mpa) for 5~10 minutes while vibrating. After the resin is cured, the powder is demoulded and then placed for 3~7 days until it is completely cured. The method requires simple equipment and is easy to implement. The obtained product has a natural texture and texture, with textures all over the surface and bottom, and the color can be adjusted as needed. It is suitable for small and medium-sized stone factories to use waste materials to produce high-quality and low-cost 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 by arranging particles through mechanical vibration is relatively low. Some processes may require the use of chemical adhesives to enhance the bonding between particles and brick embryos, which not only increases production costs, but may also cause environmental pollution. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0020] In the present 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.

[0021] like Figure 1-Figure 6 As shown, the present invention provides a technical solution: a method for manufacturing textured paving stones using marble waste, the method comprising: 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 recycling; It should be noted that by collecting scraps, broken materials and other waste materials generated during marble processing, not only the production cost is reduced, but also the resource recycling is achieved, which is in line with the concept of sustainable development; Marble waste sorting, sorting marble waste based on color; 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. Crushing and screening: crushing the classified marble waste into particles, screening the crushed particles to obtain marble aggregates of different particle sizes; It should be noted that the uniformity and applicability of aggregates are ensured, which provides a good foundation for subsequent raw material proportioning and pressing; 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 aggregates and improve the overall performance of paving stones; It should be noted that the density and strength of the aggregate are ensured to improve the overall performance of the paving stone, making it have better compression resistance, flexural resistance and wear resistance; 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; It should be noted that it can ensure that the components are evenly distributed, avoid the occurrence of local strength deficiency or defects, and improve the quality and stability of the paving stones; Pressing and molding: pouring the mixed material into a mold and pressing it to form a floor paving body of the desired shape and size; Secondary paving, laying the marble waste particles on the floor paving stone blank, the specific steps are as follows: S1: Pretreatment, roughening the surface of the paving stone; S2: dynamic mixing of marble waste particles; S3: dynamic paving of marble waste particles; Pressing and embedding: pressing the floor paving stone body, pressing and embedding the marble waste particles into the floor paving stone body; It should be noted that the close bonding between the waste particles and the blank can be ensured, thus improving the overall strength and durability of the paving stone; Brick sintering: sintering the floor paving stone blank at high temperature to form a strong chemical bond between the particles, thus improving the strength, hardness and wear resistance of the floor paving stone; It should be noted that the strength, hardness and wear resistance of paving stones have been significantly improved, making them more suitable for outdoor environments; Demolding and curing: demoulding the floor paving stones, leaving the demoulding bricks in a suitable environment to keep them moisturized, so as to stabilize the structure, release stress and improve strength, and prevent cracking and deformation in the later stage; 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 frost resistance and durability of the paving stones.

[0022] The pretreatment steps of the floor paving stone blank are as follows: L1: Clean the surface of the paving stone; It should be noted that impurities on the surface of the paving stone should be removed by cleaning.

[0023] L2: Surface treatment, mechanically scoring the surface of the paving stone embryo to achieve the required roughness; 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 particle gaps, and Rz 60-80μm further strengthens the mechanical bite force. This parameter combination balances the friction resistance and the interlocking depth, so that the volume filling rate of the waste particles is increased by 30%-40%, and the flexural strength of the finished product is increased to 12-18MPa.

[0024] The marble waste particles dynamic mixing steps are as follows: M1: Particle size ratio, mix the marble waste particles according to the particle size; It should be noted 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 the stress concentration caused by uneven particle size; 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; It should be noted that the color ratio can be accurately controlled by graded feeding to ensure uniform color and natural transition of the paving layer, meet the diverse design requirements, simulate the natural marble texture and enhance the visual appeal of the product. Based on the target color value, it is decomposed into primary color, secondary color and decorative color, and the matching ratio is set. The primary color marble waste particles are beige in color with a matching ratio of 75%, which plays a role in laying the foundation for the basic color tone. The secondary color marble waste particles are light gray in color with a matching ratio of 20%, which increases the layering and texture depth. The decorative color marble waste particles are dark brown in color with a matching ratio of 5%, which simulates the cracks and metallic luster of natural stone.

[0025] M3: Stirring and mixing. By adjusting the stirring intensity and direction, the particles are prompted to continue rolling and colliding in the mixed system, completely eliminating stratification and agglomeration; It should be noted that the stirring intensity and direction should be adjusted to cause the particles to continue rolling and colliding, 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.

[0026] The dynamic paving steps of the marble waste particles are as follows: P1: Preliminary paving: first spread the large waste particles according to the preset thickness to form a basic skeleton structure, providing high bearing capacity and permeability; It should be noted that large-particle waste forms a high-bearing capacity and permeable base structure, providing stable support for subsequent paving.

[0027] P2: Small particle filling, covering the surface of the large particle layer with small particle waste, filling the gaps and improving the surface smoothness; It should be noted that small particles cover the surface of the large particle layer, fill the gaps, reduce surface undulations, and improve the aesthetics of the paving. At the same time, the small particle filling layer and the large particle layer form an interlocking structure to improve the overall shear resistance.

[0028] P3: Dynamic speed control, according to the width of the base surface and the particle size distribution, continuously adjusts the diameter of the marble waste particles when paving, so as to dynamically adjust the total amount of marble waste particles paving, so that the floor paving surface has the performance of marble, and at the same time, simulates the texture level and transition effect of natural marble; 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.

[0029] The pressing and embedding 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 force between the particles and the brick embryo, thereby reducing pollution to the environment. Embodiment 1:
