Description

Technical Field

[0001] This invention relates to the field of sheet metal technology, and specifically to a method for manufacturing a wear-resistant and slip-resistant artificial marble slab. Background Technology

[0002] With the development of modern construction, there are increasing demands for lightweight, high-strength, aesthetically pleasing, and diverse decorative materials. Natural marble, due to its excessive rigidity but insufficient strength, is easily broken and damaged, causing difficulties in transportation and maintenance, and is thus increasingly restricted. Artificial stone, on the other hand, is processed from inexpensive waste resources or other low-cost raw materials, offering not only significant economic and social benefits but also overcoming the uneven coloring and numerous cracks inherent in natural stone.

[0003] Based on the materials used, artificial marble is divided into four main categories: cement-based, resin-based, composite, and sintered. Among them, resin-based artificial marble is the most commonly used artificial marble in daily life due to its better physical and chemical properties, ease of pattern design, and reproducibility. However, resin-based artificial marble prepared using traditional processes and formulas has poor wear resistance and slip resistance.

[0004] Chinese patent CN108821642A discloses a novel waterproof and anti-slip artificial stone, which is prepared from the following raw materials in parts by weight: 40-70 parts inorganic filler, 20-40 parts tourmaline chips, 10-30 parts rare crystal stone, 10-30 parts polyetheretherketone-perfluoropolyacrylate emulsion, 30-50 parts acrylic resin, 5-10 parts film-forming agent, 10-20 parts initiator, 5-15 parts coupling agent, and 10-20 parts inorganic pigment. This invention, by adding a polyetheretherketone-perfluoropolyacrylate coating, can achieve waterproof and oil-proof effects, anti-slip performance, and chemical corrosion resistance. However, the wear resistance of the waterproof and anti-slip artificial stone prepared by this patent is poor. Summary of the Invention

[0005] In view of this, the present invention provides a method for manufacturing a wear-resistant and slip-resistant artificial marble slab to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wear-resistant and anti-slip artificial marble slab, wherein the raw materials of the wear-resistant and anti-slip artificial marble slab include, by weight: 18-40 parts of unsaturated polyester resin, 20-35 parts of slag, 6-14 parts of limestone, 8-22 parts of magnesium oxychloride cement, 12-25 parts of fly ash, 5-17 parts of coconut shell powder, 2.5-4.8 parts of nano-silica, 1.2-2.8 parts of glass fiber, 0.5-2.4 parts of cobalt naphthenate, 6-15 parts of initiator, and 0.1-0.4 parts of curing agent.

[0007] Excessive addition of unsaturated polyester resin will release a large amount of heat during curing, causing product deformation and warping. Insufficient addition will result in poor bonding between the resin and filler, affecting the product's strength and durability. Nano-silica and ultra-fine glass fiber have high hardness, fine particle size, and good dispersibility, and they bond firmly with adhesive resin. Adding them to the raw materials can improve the hardness of marble, giving the artificial marble surface a tough and wear-resistant characteristic. Compared with ordinary silicate cement, magnesium oxychloride cement has high mechanical strength, with a compressive strength of up to 80MPa, and it also sets and hardens quickly with strong adhesion.

[0008] Furthermore, the glass fibers mentioned above are short-cut glass fibers with a particle size of 10-20 micrometers and a length of 2-8 mm.

[0009] Furthermore, the aforementioned unsaturated polyester resin is Yabang brand 7934 artificial stone resin with a solid content of 65-71% and a viscosity of (0.55-0.6) Pa•s.

[0010] Furthermore, the aforementioned initiator is one or at least two of benzoyl peroxide, methyl ethyl ketone peroxide, di-tert-butyl peroxide, and dicumyl peroxide.

[0011] Furthermore, the raw materials for preparing the above-mentioned wear-resistant and anti-slip artificial marble slab include, by weight: 27 parts unsaturated polyester resin, 28 parts slag, 10 parts limestone, 10 parts magnesium oxychloride cement, 18 parts fly ash, 11 parts coconut shell powder, 3.6 parts nano silica, 2.0 parts glass fiber, 1.5 parts cobalt naphthenate, 10 parts initiator, and 0.25 parts curing agent.

[0012] Another objective of this invention is to provide a method for manufacturing wear-resistant and slip-resistant artificial marble slabs, comprising the following steps: Step S10: Weigh the raw materials for preparing wear-resistant and anti-slip artificial marble slabs according to the above-mentioned weight proportions; Step S20: Calcine the above-mentioned parts by weight of slag at 550~660℃ for 40~80 minutes and grind it to obtain pretreated slag; Step S30: The unsaturated polyester resin, limestone, magnesium oxychloride cement, fly ash, coconut shell powder, nano silica, cobalt naphthenate, initiator, glass fiber and the pretreated slag obtained in step S20 are stirred and mixed for 5 to 10 minutes. Then the curing agent is added and stirred and mixed evenly to obtain a mixture. The stirring and mixing is carried out using a stirring and mixing device. Step S40: The mixture is loaded into the mold and vibrated to make it flat. Then, the molding machine is used to vibrate and press it to form a marble slab. Step S50: The material is sent to a curing oven for curing and then polished with a polishing machine to obtain a wear-resistant and non-slip artificial marble slab.

[0013] In this process, the curing agent and the accelerator cobalt naphthenate are added separately to avoid generating a large amount of heat during the reaction, which would affect the quality of the product. Pre-pressing with a press can prevent warping and deformation of the product during the curing process.

[0014] Furthermore, in step S40, the specific process of the above-mentioned vibration pressing molding is as follows: the molding machine is evacuated and subjected to high-frequency vibration under a pressure of 10 to 40 tons for 30 to 100 seconds.

[0015] Furthermore, in step S50, the curing conditions are as follows: first, cure at 65°C for 1.5 to 2.5 hours, and then raise the temperature to 105°C for 3 to 4 hours.

[0016] Furthermore, the mixing device includes a mixing tank, a drive mechanism, a first spiral stirring shaft, a partition, a second spiral stirring shaft, and a dispensing mechanism. The partition is disposed inside the mixing tank, dividing the mixing tank into a crushing zone and a mixing zone located below the crushing zone. The partition is provided with a discharge hole connecting the crushing zone and the mixing zone. The mixing tank is provided with a feeding cylinder for adding material to the crushing zone and a curing agent feeding hopper for adding material to the mixing zone. The first spiral stirring shaft is rotatably disposed within the crushing zone. The first spiral stirring shaft drives the material to move toward the discharge hole. The second spiral stirring shaft is rotatably disposed inside the mixing tank and drives the material to move toward the discharge port at the bottom of the mixing tank. The driving mechanism drives the first spiral stirring shaft and the second spiral stirring shaft to rotate. Several mixing blades and several scraping mechanisms are connected to the spindle of the second spiral stirring shaft. The scraping mechanisms are used to scrape off the material adhering to the inner wall of the mixing tank. The separating mechanism is used to cut the material extruded from the discharge hole.

[0017] Furthermore, the first spiral stirring shaft has a plurality of pulverizing paddles on its core shaft, and the inner wall of the pulverizing zone has a plurality of pulverizing teeth.

[0018] Furthermore, the drive mechanism includes a first motor, a first bevel gear, a second bevel gear, a rotating shaft, a first pulley, a belt, and a second pulley. One end of the first spiral stirring shaft is connected to the output shaft of the first motor, and the other end of the first spiral stirring shaft extends out of the crushing zone and is connected to the first bevel gear. The rotating shaft is rotatably disposed on the outside of the mixing box. The second bevel gear is connected to the rotating shaft and meshes with the first bevel gear. The first pulley is connected to the rotating shaft, and the second pulley is connected to the second spiral stirring shaft. The belt is sleeved on the first pulley and the second pulley.

[0019] Furthermore, the material distribution mechanism includes a second motor, a cylindrical cam, ball bearings, a right-angle connecting rod, a vibrating ball, and a guide plate. The second motor is fixedly mounted in the mixing zone. The cylindrical cam is connected to the output shaft of the second motor. The right-angle connecting rod is rotatably disposed in the mixing zone. The ball bearings are connected to one end of the right-angle connecting rod and engage with a milled groove on the outer periphery of the cylindrical cam. The vibrating ball is connected to the other end of the right-angle connecting rod and abuts against the bottom of the guide plate. One end of the guide plate is pivotally connected in the mixing zone, and a cutting blade is provided on the other end of the guide plate.

[0020] Furthermore, the mixing blade has several mixing protrusions on its cantilever end, several flow holes penetrating the upper and lower surfaces of the mixing blade, and several blade strips with several cutting edges on the upper surface of the mixing blade.

[0021] Furthermore, the scraping mechanism includes a sleeve and a movable rod telescopically disposed within the sleeve. The sleeve is connected to the second spiral stirring shaft. A compression spring is disposed between the movable rod and the sleeve. A scraper is disposed on the cantilever end of the movable rod, and a blade is disposed on the scraper. The blade abuts against the inner wall of the mixing zone.

[0022] As can be seen from the above technical solution, the advantages of the present invention are: 1. The wear-resistant and anti-slip artificial marble slab prepared by this invention contains nano-silica with high hardness, fine particle size and good dispersibility, and ultra-fine glass fiber. It is firmly bonded to the adhesive resin. Adding it to the raw materials can improve the hardness of the marble and make the surface of the artificial marble tough and wear-resistant. Magnesium oxychloride cement is used as an auxiliary binder to overcome the defects of low strength and poor mechanical properties of traditional artificial marble. The coefficient of thermal expansion of the product is improved by adding an appropriate amount of organic filler coconut shell powder. 2. The wear-resistant and anti-slip artificial marble slab manufactured by this invention has high surface hardness, high wear resistance, and excellent mechanical properties. Moreover, the raw materials are inexpensive and readily available, the preparation method is easy to operate, and the economic benefits are high, making it suitable for widespread production. 3.

The limiting pin 622 cooperates with the guide groove 613 to prevent the movable rod 62 from deflecting. A scraper 621 is disposed on the cantilever end of the movable rod 62. Several round holes 6211 are spaced apart on the scraper 621. A blade 6212 is connected to the scraper 621 and abuts against the inner wall of the mixing zone 16.

[0048] like Figure 1 As shown, when the mixing device is working, all raw materials except the curing agent are first poured into the crushing zone 11 from the feeding cylinder 13. Then, driven by the first spiral stirring shaft 21, the material moves to the left in the crushing zone 11. While the first spiral stirring shaft 21 is conveying the material, the crushing paddle 211 and the crushing teeth 12 cooperate to crush and stir the material in the crushing zone 11, so that the components in the material are initially mixed evenly. Then, driven by the first spiral stirring shaft 21, the material is squeezed out from the discharge nozzle 33. At the same time as the material is squeezed out from the discharge nozzle 33, the cutter 48 moves up and down under the drive of the guide plate 46 to cut the material squeezed out from the discharge nozzle 33, so that the material is cut into several small parts and falls into the mixing zone 16, which is beneficial to Regarding the mixing of materials, after the materials fall into the mixing zone 16, the mixing blades 5 and scraping mechanism 6 agitate the materials under the drive of the second spiral stirring shaft 27 to make the materials more uniformly mixed. After the materials are fully mixed, the user adds curing agent into the mixing zone 16 from the curing agent feeding hopper 14. The second spiral stirring shaft 27 continues to rotate, driving the mixing blades 5 and scraping mechanism 6 to agitate and mix the curing agent with the materials until a mixture is obtained. Then, the discharge valve at the discharge port 161 is opened, and the materials move downward under the push of the second spiral stirring shaft 27. With the cooperation of the feeding plate 28, the mixture is discharged from the discharge port 161. This mixing device uses graded stirring and a distribution mechanism to distribute the materials, resulting in a high degree of uniformity in the mixture.
