Description

A flame-retardant wood-plastic composite door panel and its processing method Technical Field

[0001] This invention relates to the field of wood-plastic composite door panel technology, specifically to a flame-retardant wood-plastic composite door panel and its processing method. Background Technology

[0002] Wood-plastic composite (WPC) door panels are made from a composite material formed by combining wood fibers and thermoplastic plastics through a special process. This material combines the aesthetics of wood with the durability of plastic, offering excellent heat and sound insulation, easy cleaning and maintenance, and lightweight construction for convenient installation. WPC door panels come in a rich variety of colors and textures to mimic natural wood, catering to diverse interior design styles. Flame retardancy is crucial for WPC door panels, especially in residential and public buildings. While WPC itself possesses some flame-retardant properties, this is insufficient to fully meet modern building fire safety regulations. Therefore, flame retardants are typically added during the production of WPC door panels to enhance their fire resistance. These flame retardants act rapidly upon contact with a fire source, forming a protective film that isolates oxygen and heat, slowing the spread of flames and buying valuable time for evacuation.

[0003] To enhance fire resistance, current wood-plastic composite door panels often have a layer of heat-resistant fire-retardant board installed or attached, creating a sandwich structure. While this improves the flame-retardant effect, these door panels still have the following problems:

[0004] 1. When the heat is concentrated in one area on the surface of the wood board, the heat is relatively concentrated, which makes it easy to reach high temperature and start to burn, resulting in poor flame retardant effect;

[0005] 2. When the fireproof board is attached to the surface of the door panel, there is a lack of resistance between the two mating surfaces, which makes the fireproof board prone to shifting during the attachment process and easy to peel off after attachment, reducing the stability of the structure.

[0006] In summary, there is a current need for a wood-plastic composite door panel that is thermally conductive, flame-retardant, and structurally stable. Summary of the Invention

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example 1

[0048] To address the technical problems in the background section, the following flame-retardant wood-plastic composite door panel and its processing method are provided:

[0049] As shown in Figures 1 and 2, the present invention provides a flame-retardant wood-plastic composite door panel, comprising a door panel body 1. The door panel body 1 has multiple second inner slots 13 inside, each containing a graphene core 2. Waterproof grooves 11 are formed on both sides of the door panel body 1. A first inner slot 12 is formed between the second inner slots 13 and the waterproof grooves 11, containing a steel inner liner 3. An attachment groove 14 is formed on the top surface of the door panel body 1. Two attachment grooves 14 are mirror images of the horizontal centerline of the door panel body 1. The attachment grooves 14 have an inverted trapezoidal groove structure. Fireproof boards 4 are attached to both the top and bottom surfaces of the door panel body 1. A heat-conducting plate 41, also inverted trapezoidal in structure, is provided on the side of the fireproof board 4 closest to the door panel body 1. The heat-conducting plate 41 fits into the attachment groove 14.

[0050] The following effects can be achieved based on the above structure:

[0051] 1. By inserting a graphene core 2 into the second inner slot 13 of the door panel body 1, the graphene core 2 can form a barrier in the door panel body 1 to prevent the transfer of oxygen and heat. Moreover, the high thermal conductivity of graphene helps to dissipate heat quickly. Combined with the fireproof board 4 structure with heat-conducting plate 41, it is beneficial to reduce the surface temperature, thereby reducing the possibility of combustion and delaying the combustion process, and improving the flame retardant effect of the door panel.

[0052] 2. The heat-conducting plate 41 on the fireproof board 4 is attached to the inside of the inverted trapezoidal attachment groove 14, which increases the attachment area and ensures the stability of the structure after attachment.

[0053] Example 2

[0054] As shown in Figures 1-12, the present invention provides a processing method for flame-retardant wood-plastic composite door panels, the processing method comprising the following steps:

[0055] S1, Preparation of door panel 1;

[0056] The raw materials for preparing door panel 1 are mixed in proportion, stirred evenly with a mixer, fed into an extruder and extruded into a hollow panel structure, then cooled and cut to obtain door panel 1 of standard size, and the surface of door panel 1 is polished and cleaned.

[0057] The raw materials for preparing door panel 1 include 70-100 parts of PVC resin, 20-30 parts of wood flour, 20-30 parts of calcium carbonate, 15-20 parts of smoke suppressant, 10-15 parts of flame retardant, 1-6 parts of foaming agent, 5-10 parts of stabilizer, 1-2 parts of coupling agent, 5-10 parts of processing aid, and 1-4 parts of lubricant.

[0058] S2, fixed plate interior;

[0059] The door panel 1 is sent into the assembly equipment and the internal assembly of the flame-retardant wood-plastic door panel as described in claim 1 is positioned and assembled.

[0060] The assembly equipment includes a feeding mechanism 5, a plate fixing mechanism 6, a pushing mechanism 7, and an inserting mechanism 8. The door panel 1 is positioned inside the plate fixing mechanism 6 after passing through the feeding mechanism 5, and the inserting mechanism 8 inserts the graphene core 2 and the steel liner 3 into the door panel 1.

[0061] The specific steps are as follows: Place the door panel 1 on the first loading platform 51 and fit it against the elastic sleeve 521. Start the electric roller 52 to push the door panel 1 through the bottom of the plate assembly 53 with the fireproof board 4 wound on it. Insert the door panel 1 between the two sets of rolling and pushing assemblies 74 of the pushing mechanism 7. Start the first motor 62 to drive the first screw 63 to rotate, so that the pushing mechanism 7 as a whole moves the door panel 1 towards the insertion mechanism 8. The fixed frame 71 drives the top plate 75 to move and separate from the top column 535. The first spring 534 pulls the bearing column 532 down to make the drum 531 descend. At the same time, start the second motor 741 to drive the rotating shaft 744 to rotate, so that the pushing roller 743 rotates and pushes the door panel 1 to move quickly to the second loading platform 81. At the same time, the pushing roller 743 rolls and fits against the top block 643, and the side guard wheel 764 rolls and fits against the side of the door panel 1 to ensure the stability of the door panel 1 conveying.

[0062] The first pneumatic rod 645 is activated to push the locking block 643. The locking block 643 pushes the push roller 743 to slide on the rotating shaft 744 and stretch the second spring 745. The chamfered structure at one end of the push roller 743 fits into the inclined surface inside the attachment groove 14 of the door panel 1, thereby accurately positioning the door panel 1.

[0063] Then, multiple graphene cores 2 are placed on the pad 85, and the steel liner 3 is placed in the side slot 851 and separated by the partition plate 654. The third motor 83 is started to drive the second screw 86 to rotate. The second push plate 84 pushes the graphene cores 2 and the steel liner 3 and inserts them into the second inner slot 13 and the first inner slot 12 of the door panel 1, respectively. When the second push plate 84 moves to the position of the partition plate 654, the graphene cores 2 and the steel liner 3 can be stably inserted into the door panel 1. The second pneumatic rod 652 is started to push the first push plate 653 to rise, raising the partition plate 654. The first push plate 653 continues to push the graphene cores 2 and the steel liner 3 to be fully inserted into the door panel 1.

[0064] S3. Send board for exterior decoration;

[0065] The pushing mechanism 7 pushes the door panel 1 out from inside the feeding mechanism 5. At the same time, the feeding mechanism 5 attaches the fireproof board 4 to the door panel 1. Then the door panel 1 is flipped over, and the pushing mechanism 7 pushes the fireproof board 4 back and forth. The feeding mechanism attaches the fireproof board 4 to the other side of the door panel 1, thus completing the door panel assembly.

[0066] The specific steps are as follows: the first motor 62 and the second motor 741 are started to transport the inner door panel 1 in reverse. When the door panel 1 is guided to move to the bottom of the drum 531, the glue injection box 542 is started to inject glue into the glue brush plate 544. The glue brush plate 544 applies the glue to the fireproof board 4 and the heat-conducting plate 41. The drum 531 is rotated to attach the fireproof board 4 to the door panel 1. The heat-conducting plate 41 is inserted into the attachment groove 14. Then, it is rolled by the elastic sleeve 521 and transported out. After it is completely attached, the top plate 75 pushes up the top column 535 to cut the fireproof board 4 to ensure that the attachment edge is flush. Then, the door panel 1 is flipped over and transported, and the fireproof board 4 is attached to the other side of the door panel 1.

[0067] By sending the door panel 1 into the assembly equipment for positioning, and then assembling the internal and external components onto the door panel 1 in sequence, a complete flame-retardant wood-plastic door panel is obtained. The assembly can be completed simply by moving the door panel 1 back and forth, which improves the assembly efficiency and accuracy of the door panel.

[0068] In this embodiment, the feeding mechanism 5 includes a first feeding platform 51, an electric roller 52, a plate attaching assembly 53, and an adhesive applicator 54. A plate fixing mechanism 6 is provided on one side of the first feeding platform 51, an electric roller 52 is provided on the top surface of the first feeding platform 51, an elastic sleeve 521 is sleeved on the outer wall of the electric roller 52, a plate attaching assembly 53 for attaching fireproof board 4 is provided on the top surface of the first feeding platform 51, an adhesive applicator 54 is provided on one side of the plate attaching assembly 53, and one side of the adhesive applicator 54 is fixed to the top surface of the plate fixing mechanism 6.

[0069] The fixed plate mechanism 6 includes a side support plate 61, a first motor 62, a first screw 63, a push-lock assembly 64, and a guide assembly 65. Two side support plates 61 are arranged in parallel, and a push mechanism 7 is slidably connected between the two side support plates 61. The first motor 62 is provided on the outer wall of the side support plate 61, and the rotating end of the first motor 62 is connected to the first screw 63. The first screw 63 is threadedly connected to the inside of the push mechanism 7. The push mechanism 7 is pushed and translated between the two side support plates 61 by the first screw 63. The push-lock assembly 64 is fixed between the two side support plates 61. One side of the push-lock assembly 64 is connected through the inside of the push mechanism 7. An inserting mechanism 8 is provided on the side of the side support plate 61 away from the first loading platform 51.

[0070] The pushing mechanism 7 includes a fixed frame 71, a hot air blower 72, a fixed frame 73, a rolling push assembly 74, a top plate 75, and a side rolling assembly 76. Slide plates 711 are fixed on both sides of the fixed frame 71. The slide plates 711 are slidably connected to the inside of the side support plate 61. The first screw 63 is threadedly connected to the inside of the slide plates 711. Hot air blowers 72 are provided on the top and bottom surfaces inside the fixed frame 71. A fixed frame 73 is fixed inside the fixed frame 71. There are two fixed frames 73 mirror images of the vertical center line of the fixed frame 71. A side rolling assembly 76 is connected to one side of the fixed frame 73. A rolling push assembly 74 is connected between the two fixed frames 73. There are two sets of rolling push assemblies 74 mirror images of the horizontal center line of the fixed frame 73. A top plate 75 is fixed on the side of the fixed frame 71 near the plate assembly 53.

[0071] The door panel 1 is pushed into the roller push assembly 74 by the electric roller 52. The roller push assembly 74 quickly conveys the door panel 1 to the insertion mechanism 8. Then, the roller push assembly 74 is pushed and adjusted by the locking and pushing assembly 64. The first screw 63 drives the roller push assembly 74 to move back and forth between the two side plates so that the roller push assembly 74 is positioned on the door panel 1. Then, the graphene core 2 and the steel liner 3 can be accurately inserted through the insertion mechanism 8, which improves the accuracy and efficiency of conveying and inserting.

[0072] After the door panel 1 is installed, the push component pushes the installed door panel 1 in the opposite direction, accurately delivering the door panel 1 to the bottom of the adhesive board component 53, and accurately pasting the fireproof board 4 with glue applied by the adhesive application component 54 onto the door panel 1, thus improving the convenience of pasting the fireproof board 4.

[0073] When conveying the door panel 1, the hot air blower 72 heats and cleans the surface of the door panel 1 that it passes through, and can guide the hot air from both sides of the door panel 1 to the middle along the inclined surface of the groove 14 attached to the surface of the door panel 1, thereby improving the heating uniformity and the effect of the fireproof board 4 being attached to the door panel 1.
