Description

Technical Field

[0001] This invention relates to a low-gloss floor, and more particularly to a low-gloss floor based on a rough surface and its manufacturing process. Background Technology

[0002] Compared to regular high-gloss flooring, low-gloss flooring is increasingly used as indoor flooring due to its advantages such as reducing glare and alleviating eye strain. Currently, manufacturers reduce the surface gloss of flooring in two ways: physical matting and chemical matting. Physical matting increases the roughness of the floor surface coating through various means, causing light to reflect slowly when it hits the surface. Chemical matting, on the other hand, involves adding matting powder to the surface coating, which absorbs light-emitting groups to achieve a low-gloss effect.

[0003] For physical matte finishing, manufacturers typically rub the surface of the flooring with a roller or sandpaper of a certain roughness after the paint layer has been processed and formed. This creates a similar rough surface on the paint layer, achieving a low-gloss effect. However, this process has two drawbacks. First, it is difficult to create significant undulations in the fully cured paint layer of the flooring surface through direct friction, thus reducing the diffuse reflection effect of the flooring surface. Second, over long-term use, the raised parts of the flooring surface are easily worn down, turning the original rough surface into a smooth surface and destroying its diffuse reflection effect.

[0004] Therefore, a processing technology is needed to improve the diffuse reflection effect of the floor surface. Summary of the Invention

[0005] The purpose of this invention is to provide a low-gloss flooring based on a rough surface and its manufacturing process. It can increase the roughness of the flooring surface and alleviate the wear and tear caused by long-term use.

[0006] The technical solution of the present invention is as follows: a low-gloss floor based on a rough surface, comprising a floor body, the surface of which is sequentially coated with a primer layer, an intermediate layer and a topcoat layer, a plurality of matte powders are attached to the upper surface of the intermediate layer, the lower end of the matte powders is interlocked with the intermediate layer, the upper end of the matte powders is completely adhered to the topcoat layer, and the upper surface of the topcoat layer forms a rough surface that matches the matte powders.

[0007] The aforementioned manufacturing process for low-gloss flooring based on rough surfaces includes the following steps:

[0008] ① Apply a UV primer to the surface of the floor and allow it to fully cure to obtain product A;

[0009] ② Coat the surface of product A with UV intermediate paint and process it to a semi-cured state to obtain product B;

[0010] ③ Spray matte powder onto the surface of the UV intermediate paint of product B to obtain product C;

[0011] ④ The surface of product C is coated with multiple rollers in sequence, so that the matte powder on the surface of product C is evenly covered on the surface of the UV intermediate paint by the roller coating, thus obtaining product D.

[0012] ⑤ Process the UV intermediate paint on the surface of product D until it is fully cured to obtain product E;

[0013] ⑥ Apply a topcoat to the surface of product E to obtain the finished product.

[0014] In the aforementioned production process, the coating height of the multiple rollers in step ④ decreases sequentially.

[0015] In the aforementioned production process, after the roller coating of product D is completed in step ④, the matte powder floating on the surface of product D is removed by blowing, so that the matte powder attached to the surface of product D and the UV intermediate paint form an interlocking state.

[0016] In the aforementioned production process, the process is carried out using a low-gloss coating device. The low-gloss coating device includes a conveyor belt, and a mounting frame is provided on the top of the conveyor belt. A spraying assembly and a roller assembly are sequentially arranged on the mounting frame along the floor conveying direction. The roller assembly includes multiple sanding rollers arranged side by side on the mounting frame. The ends of the sanding rollers are connected to a swing frame via a drive shaft. The upper end of the swing frame is rotatably connected to the mounting frame via a swing shaft. Positioning plates are provided on both sides of the sanding rollers. Positioning pins are slidably connected to the positioning plates. Guide rods and fixing nuts are respectively connected to the positioning pins. The middle part of the guide rod is slidably connected to the drive shaft via multiple guide holes.

[0017] In the aforementioned production process, the drive shaft is connected to the swing shaft via a first sprocket transmission assembly at the end away from the sanding roller, and adjacent swing shafts are connected to each other via a second sprocket transmission assembly. One of the swing shafts is externally connected to a drive motor.

[0018] In the aforementioned production process, the drive shaft is externally rotatably connected to a sliding sleeve, which is slidably connected to the swing frame. One side of the sliding sleeve is provided with a tensioning screw for the swing frame that is threadedly connected to it.

[0019] In the aforementioned production process, the swing shaft is connected to a mounting bracket via a seated bearing, and the mounting bracket is provided with an elongated hole for the seated bearing to move laterally.

[0020] In the aforementioned manufacturing process, one end of the guide rod is connected to a positioning pin via a round hole, and the other end of the guide rod is connected to a positioning pin via a long strip connecting hole.

[0021] In the aforementioned production process, the bottom of the positioning pin is provided with an adjusting screw that is threadedly connected to the positioning plate, and the end of the adjusting screw is in contact with the positioning pin.

[0022] Compared with the prior art, the present invention has the following characteristics:

[0023] (1) By attaching matte powder to the surface of the intermediate layer, the topcoat layer can form a rough surface after coating with the unevenness of the matte powder, thereby effectively improving the surface undulation effect and roughness compared with the rough surface structure generated by conventional friction; at the same time, the undulation effect formed by the matte powder after protrusion can also effectively alleviate the wear of the surface paint layer of the floor after long-term use, thereby improving the stability of the rough surface.

[0024] (2) Based on the above, the present invention optimizes the floor production process so that the matte powder can be uniformly attached to the semi-cured UV intermediate paint by roller coating and cured together with the UV intermediate paint. With this process, the matte powder can maintain an interlocking state with the UV intermediate paint after attachment, thereby improving the adhesion stability of the UV intermediate paint to the matte powder and preventing the matte powder from loosening and falling off in subsequent processes and use.

[0025] (3) By using multiple rollers of different heights to roll the matte powder, and blowing away the matte powder that has not been in contact with the UV intermediate paint after the roll coating is completed, the uniformity of matte powder adhesion on the UV intermediate paint surface can be effectively improved. On the one hand, the matte powder is continuously spread out during the roll coating process, avoiding the decrease in uniformity caused by agglomeration. On the other hand, it can also prevent the agglomerated matte powder from being pressed into the UV intermediate paint as a whole due to the roller pressing too deeply at one time, thereby causing irregular undulations on the surface of the UV intermediate paint and excessive consumption of matte powder.

[0026] (4) Based on the above process, by limiting the structure of the low gloss coating device, on the one hand, each sanding roller can be staggered up and down within a specified height interval, thereby ensuring the stability of the UV intermediate coating; on the other hand, each roller assembly can also realize the tensioning function, thereby driving the device with only a single motor through the cooperation of the first sprocket drive assembly and the second sprocket drive assembly, which reduces the equipment cost of the present invention.

[0027] (5) By matching the structure of the positioning pin and the guide rod, the operator can adjust the height of each sand sleeve roller by simply adjusting the height of the positioning pin on both sides, thereby further reducing the complexity of the operator's operation.

[0028] Therefore, the present invention can increase the roughness of the floor surface and alleviate the wear and tear on the rough surface after long-term use of the floor. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0034] Example. A low-gloss floor based on a rough surface, configured as follows: Figure 1 As shown, the floor includes a floor body 100. The surface of the floor body 100 is sequentially coated with a primer layer 200, an intermediate layer 300, and a topcoat layer 400. The upper surface of the intermediate layer 300 is coated with a plurality of matte powders 500. The lower ends of the matte powders 500 are interlocked with the intermediate layer 300, and the upper ends of the matte powders 500 are completely adhered to the topcoat layer 400. The upper surface of the topcoat layer 400 forms a rough surface that matches the matte powders 500. The surface undulation effect of this rough surface is consistent with the surface undulation effect formed on the intermediate layer 300 after the matte powders 500 are applied.

[0035] The manufacturing process for this low-gloss floor includes the following steps:

[0036] ① Apply a UV primer to the surface of the floor and allow it to fully cure to obtain product A;

[0037] ② Coat the surface of product A with UV intermediate paint and process it to a semi-cured state to obtain product B;

[0038] ③ Spray matte powder onto the surface of the UV intermediate paint of product B to obtain product C;

[0039] ④ The surface of product C is coated with multiple rollers in sequence, so that the matte powder on the surface of product C is evenly covered on the surface of the UV intermediate paint by the roller coating, thus obtaining product D.

[0040] ⑤ Process the UV intermediate paint on the surface of product D until it is fully cured to obtain product E;

[0041] ⑥ Apply a topcoat to the surface of product E to obtain the finished product.

[0042] In step ④, the coating height of the multiple rollers decreases sequentially.

[0043] In step ④, after the roller coating of product D is completed, the matte powder floating on the surface of product D is removed by blowing, so that the matte powder adhering to the surface of product D and the UV intermediate paint form an interlocking state.

[0044] This production process utilizes a low-gloss coating device, which is configured as follows: Figure 2 As shown, the system includes a conveyor belt 1 with locking blocks for limiting the floorboards to prevent slippage or deviation during transport. A mounting frame 2 is located at the top of the conveyor belt 1, and a spraying assembly 4 and a roller assembly 5 are sequentially mounted on the mounting frame 2 along the floorboard transport direction. The spraying assembly 4 consists of conventional processing equipment for spraying powder particles. The roller assembly 5 includes multiple sanding rollers 6 arranged side-by-side on the mounting frame 2. The ends of the sanding rollers 6 are connected to a swing frame 8 via a drive shaft 7. The upper end of the swing frame 8 is rotatably connected to the mounting frame 2 via a swing shaft 9. The swing frame 8 and the swing shaft 9 are connected by bearings. Positioning plates 10 are provided on both sides of the sanding rollers 6 to connect to the mounting frame 2. Positioning pins 11 are slidably connected to the positioning plates 10, and guide rods 12 and fixing nuts 3 are connected to the positioning pins 11 respectively. The middle part of the guide rods 12 is slidably connected to the drive shaft 7 via multiple elongated guide holes 13.

[0045] The drive shaft 7 is connected to the swing shaft 9 via a first sprocket drive assembly at the end away from the sanding roller 6. Adjacent swing shafts 9 are connected to each other via a second sprocket drive assembly. One of the swing shafts 9 is externally connected to a drive motor. Both the first and second sprocket drive assemblies are conventional sprocket and chain drive structures.

[0046] The drive shaft 7 is externally rotatably connected to a sliding sleeve 14, which is slidably connected to the swing frame 8. The sliding sleeve 14 is made of a split sleeve and a cover connected by threads. After being positioned, the sliding sleeve 14 is fixed to the swing frame 8 by tightening. One side of the sliding sleeve 14 is provided with a tensioning screw 15 that is threadedly connected to the swing frame 8.

[0047] The swing shaft 9 is connected to the mounting bracket 2 via a bearing seat, and the mounting bracket 2 is provided with an elongated hole 16 for the bearing seat to move laterally.

[0048] One end of the guide rod 12 is connected to the positioning pin 11 through a round hole, and the other end of the guide rod 12 is connected to the positioning pin 11 through a long strip connecting hole.

[0049] The bottom of the positioning pin 11 is provided with an adjusting screw 17 that is threadedly connected to the positioning plate 10, and the end of the adjusting screw 17 is in contact with the positioning pin 11.

[0050] The working principle of this invention is as follows: During installation, the first and second sprocket drive assemblies are first fitted onto the outside of the drive shaft 7 and the swing shaft 9. Then, the chain is tensioned by moving the swing frame 8 and the sliding sleeve 14. The spacing between adjacent swing shafts 9, and between the drive shaft 7 and the swing shaft 9 on each swing frame 8, is kept as consistent as possible, thus ensuring that the horizontal spacing of each sanding roller 6 is uniform. After installation, the operator adjusts the height of the positioning pins 11 on both sides using the adjusting screw 17, thereby fine-tuning the height and tilt angle of the guide rod 12. After positioning, the guide rod 12 limits the height of each sanding roller 6, achieving rapid positioning of multiple sanding rollers 6. After positioning, the guide rod 12 is locked onto the positioning plate 10 by the fixing nut 3, preventing the sanding rollers 6 from shaking during use.

[0051] In use, this invention first uses the spraying assembly 4 to spray matte powder 500 onto the UV intermediate coat surface of the floor. Then, the abrasive rollers 6 of the roller assembly 5 sequentially rub the surface of the UV intermediate coat, causing the matte powder 500 on the UV intermediate coat to spread to one side and contact the UV intermediate coat during the friction, thereby preventing the matte powder 500 from agglomerating and piling up on the UV intermediate coat surface. By continuously lowering the height of the roller assembly 5, it is also possible to effectively prevent the agglomerated matte powder 500 from being directly pressed into the UV intermediate coat due to excessive penetration during the friction, thus improving the adhesion of the matte powder 500 to the UV intermediate coat surface and increasing the utilization rate of the matte powder 500.
