Description

Technical Field

[0001] This invention relates to the field of SPC wall panel technology, specifically to a method for manufacturing high-gloss 3D printed film painted SPC wall panels. Background Technology

[0002] SPC wall panels, also known as stone crystal wall panels, are mainly used in interior decoration. Due to their advantages, they have gradually replaced some of the wallpaper, tiles and other wall decorations in the market and are very popular. The main advantages of their popularity are that they are formaldehyde-free and easy to install.

[0003] However, due to limitations in raw materials, the wall panels have limited color options, and the quality of the raw materials may also affect the quality of the finished SPC wall panels. In particular, the light transmittance of polyvinyl chloride resin powder and calcium carbonate powder is a concern. If the light transmittance of these two raw materials is poor, the finished SPC wall panels may have low brightness, appear dull, and affect the overall aesthetics.

[0004] In summary, it is necessary to design an SPC wall panel with richer colors and higher brightness to meet the above requirements. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a method for manufacturing high-gloss 3D printed film painted SPC wall panels, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A method for manufacturing high-gloss 3D printed film painted SPC wall panels includes a light transmittance testing device. The light transmittance testing device includes a light source base, which includes a housing. A support base is fixed to the bottom of the housing. A lamp tube is installed inside the housing along its length. The lamp tube irradiates polyvinyl chloride resin powder or calcium carbonate powder on the material hopper from the bottom. A material hopper is installed on the top of the light source base. The material hopper includes a material hopper plate with a trapezoidal cross-section. Baffles are fixed to the top of both sides of the material hopper plate. An end plate is fixed to the top of one end of the material hopper plate. A light-transmitting structure is provided on the material hopper plate. The light-transmitting structure includes a long groove formed in the material hopper plate, and a light-transmitting glass plate is fixed in the long groove.

[0008] To spread polyvinyl chloride resin powder or calcium carbonate powder evenly on the spreading plate for easy irradiation, a spreading structure is slidably installed between two baffles. The spreading structure includes two symmetrically arranged U-shaped blocks, the openings of which are slidably installed on the two baffles. An installation plate is fixed between the two baffles, and an elastic scraper is installed below the installation plate.

[0009] To achieve the lifting and lowering of the scraper, the mounting plate has round holes near both ends, and guide rods are slidably installed in the round holes. The upper and lower ends of the guide rods extend out of the round holes. A limit plate is fixed to the upper end of the guide rod, and a spring is fixed between the limit plate and the mounting plate. The spring is sleeved on the guide rod, and the lower ends of the two guide rods are fixed to the top of the scraper.

[0010] It also includes the following steps:

[0011] Step 1: The main raw materials are polyvinyl chloride resin powder, calcium carbonate powder, calcium zinc stabilizer, stearic acid, PE wax, and anti-toughness and impact-resistant additives. The proportions of the raw materials are as follows: 60 parts polyvinyl chloride resin powder, 200 parts 350 calcium carbonate powder, 4 parts calcium zinc stabilizer, 1 part PE wax, and 1 part anti-toughness and impact-resistant additives.

[0012] Step 2: Conduct light transmittance testing on polyvinyl chloride resin powder and calcium carbonate powder using a light transmittance testing device;

[0013] Step 3: Mix the raw materials from Step 1 according to the formula, then extrude them through an extruder, and finally calender the extruded material into sheets through a calender.

[0014] Step 4: Use a 3D printer to print the desired pattern on the substrate layer;

[0015] Step 5: On the SPC production line, the base layer is directly laminated, which is a pure white PVC film. On the flat lamination and adhesive production line, the decorative layer is laminated, which is a high-gloss PET transparent film.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The finished SPC wall panel of this invention uses a 3D printer to print patterns on the substrate layer, which is fast and increases the color of the wall panel. By setting a decorative layer, the overall aesthetics are enhanced. Moreover, the decorative layer is a high-gloss PET transparent film, which makes the finished SPC wall panel brighter and prevents it from appearing dull.

[0018] 2. Before producing SPC wall panels, this invention conducts a light transmittance test on polyvinyl chloride resin powder or calcium carbonate powder to check its quality, thereby ensuring the quality of the finished SPC wall panels. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] This invention provides a method for manufacturing high-gloss 3D printed film painted SPC wall panels, comprising the following steps:

[0027] Step 1: The main raw materials are polyvinyl chloride resin powder, calcium carbonate powder, calcium zinc stabilizer, stearic acid, PE wax, and anti-toughness and impact-resistant additives. The proportions of the raw materials are as follows: 60 parts polyvinyl chloride resin powder, 200 parts 350 calcium carbonate powder, 4 parts calcium zinc stabilizer, 1 part PE wax, and 1 part anti-toughness and impact-resistant additives.

[0028] Step 2: Conduct light transmittance testing on polyvinyl chloride resin powder and calcium carbonate powder using a light transmittance testing device;

[0029] Step 3: Mix the raw materials from Step 1 according to the formula, then extrude them through an extruder, and finally calender the extruded material into sheets through a calender.

[0030] Step four: Use a 3D printer to print the required graphic on the substrate layer. Compared to the traditional sticker method, using a 3D printer is faster and more convenient for printing graphics.

[0031] Step 5: On the SPC production line, the base layer is directly laminated with a pure white PVC film. On the flat lamination and adhesive lamination production line, the decorative layer is laminated with a high-gloss PET transparent film, which can improve the brightness of the finished PVC.

[0032] like Figure 1-2 , Figure 4-5As shown, the light transmittance testing device of the present invention specifically includes a light source base, which includes a housing 1. A support base 2 is fixed at the bottom of the housing 1. A lamp tube 3 is installed inside the housing 1 along its length. The lamp tube 3 is powered by an external power source. The lamp tube 3 irradiates the polyvinyl chloride resin powder or calcium carbonate powder on it from the bottom of the material hopper. A material hopper is installed on the top of the light source base. The material hopper includes a material plate 4. The material plate 4 has a trapezoidal cross-section. Baffles 5 are fixed on the top of both sides of the material plate 4. An end plate 6 is fixed on the top of one end of the material plate 4. A light-transmitting structure is provided on the material plate 4. The light-transmitting structure includes a long groove opened on the material plate 4. A light-transmitting glass plate 7 is fixed in the long groove.

[0033] like Figure 2-3 As shown, in order to spread the polyvinyl chloride resin powder or calcium carbonate powder evenly on the spreading plate 4 for easy irradiation, a spreading structure is slidably installed between two baffles 5. The spreading structure includes two symmetrically arranged U-shaped blocks 8, the openings of which are slidably installed on the two baffles 5. A mounting plate 9 is fixed between the two baffles 5, and an elastic scraper 10 is installed below the mounting plate 9. The lamp tube 3 is turned on by connecting to an external power source to emit light, and the polyvinyl chloride resin powder or calcium carbonate powder on the flat plate is irradiated through the transparent glass plate 7 to observe the light transmittance of the polyvinyl chloride resin powder or calcium carbonate powder. If the light transmittance is poor, it indicates that the quality of the polyvinyl chloride resin powder or calcium carbonate powder is poor. After the light transmittance test of the polyvinyl chloride resin powder or calcium carbonate powder is completed, turn off the lamp tube 3, press the mounting plate 9 with one hand and press the guide rod 11 down with the other hand to push the lower end of the scraper 10 against the top of the spreading plate 4. Then push the mounting plate 9 from the end plate 6 to the other end of the spreading plate 4, thereby driving the scraper 10 to move and detach the polyvinyl chloride resin powder or calcium carbonate powder from the end plate 6 to the other end of the spreading plate 4, so as to realize the unloading of polyvinyl chloride resin powder or calcium carbonate powder on the spreading plate 4.

[0034] like Figure 4-5As shown, to achieve the lifting and lowering of the scraper 10, the mounting plate 9 has round holes near both ends. Guide rods 11 are slidably installed in the round holes, with both the upper and lower ends of the guide rods 11 extending out of the round holes. A limit piece 12 is fixed to the upper end of the guide rod 11, and a spring 13 is fixed between the limit piece 12 and the mounting plate 9. The spring 13 is fitted onto the guide rod 11, and the lower ends of both guide rods 11 are fixed to the top of the scraper 10. A portion of polyvinyl chloride resin powder or calcium carbonate powder is taken out of the nylon bag and placed on the spreading plate 4. One hand holds the mounting plate 9, and the guide rods 11 are pulled upwards, causing the scraper 10 to move upwards. Move upwards. At this time, spring 13 is compressed, leaving a gap between scraper 10 and spreading plate 4. Then, push the mounting plate 9 with one hand to move it, thereby moving scraper 10. U-shaped block 8 slides along baffle 5 to spread polyvinyl chloride resin powder or calcium carbonate powder on spreading plate 4. Baffle 5 and end plate 6 can prevent polyvinyl chloride resin powder or calcium carbonate powder from falling off spreading plate 4. When polyvinyl chloride resin powder or calcium carbonate powder is spread into a thin layer on spreading plate 4, release the hand pressing the mounting plate 9 and lifting guide rod 11.

[0035] Finally, the most significant contribution of this invention is that the finished SPC wall panel uses a 3D printer to print patterns on the substrate layer, resulting in fast printing speed, increased color of the wall panel, and enhanced overall aesthetics through the addition of a decorative layer. Moreover, the decorative layer is a high-gloss PET transparent film, which makes the finished SPC wall panel brighter and prevents it from appearing dull. Before producing the SPC wall panel, the light transmittance of the polyvinyl chloride resin powder or calcium carbonate powder is tested to check its quality, thereby ensuring the quality of the finished SPC wall panel.
