[0024] Please refer to Figures 1-4. This utility model provides an embodiment of a flame-retardant high closed-cell rate carved decorative part, including an outer frame 1 and a fixed frame 3. A connecting frame 2 is fixedly connected to the inner wall of the outer frame 1, and a fixed frame 3 is provided inside the outer frame 1. A first high closed-cell filling layer 7 is fixedly connected to the front end and the rear end of the outer frame 1 and the fixed frame 3, respectively. A second high closed-cell filling layer 9 is fixedly connected to the outside of the first high closed-cell filling layer 7. A second filling material 10 is provided inside the second high closed-cell filling layer 9, and a first filling material 8 is provided inside the first high closed-cell filling layer 7.
[0025] The first filler material 8 is aluminum hydroxide, and the second filler material 10 is expanded graphite;
[0026] Specifically, as shown in Figures 1, 3, and 4, a first high-closed-cell filling layer 7 is fixedly connected to the front and rear ends of the outer frame 1 and the fixed frame 3, respectively. A second high-closed-cell filling layer 9 is fixedly connected to the outside of the first high-closed-cell filling layer 7. A second filling material 10 is disposed inside the second high-closed-cell filling layer 9. A first filling material 8 is disposed inside the first high-closed-cell filling layer 7. The first filling material 8 is made of aluminum hydroxide, and the second filling material 10 is made of expanded graphite. The aluminum hydroxide and expanded graphite enhance the flame retardancy through chemical copolymerization or physical mixing. When exposed to fire, the closed-cell structure expands to form a dense carbonized layer, which slows down the spread of flames and does not release toxic fumes, making it safer to use and improving flame retardancy.
[0027] The four corners at the front end of the connecting frame 2 are provided with mounting grooves 6. The interior of the fixed frame 3 is fixedly connected with carved blocks 4. The four corners at the rear end of the fixed frame 3 are fixedly connected with positioning blocks 5. The positioning blocks 5 are embedded in the interior of the mounting grooves 6 and are detachable.
[0028] Specifically, as shown in Figures 1 and 2, mounting slots 6 are provided at the four corners of the front end of the connecting frame 2, and carved blocks 4 are fixedly connected inside the fixed frame 3. Positioning blocks 5 are fixedly connected at the four corners of the rear end of the fixed frame 3. The positioning blocks 5 are embedded in the mounting slots 6 and are detachable. When replacing or assembling the carved blocks 4, the positioning blocks 5 at the rear end of the fixed frame 3 can be inserted into the mounting slots 6 in the connecting frame 2 for fixation, making it convenient and quick to assemble and replace.
[0029] The material of the first high closed-cell filling layer 7 is flame-retardant polyurethane, and the material of the second high closed-cell filling layer 9 is phenolic resin.
[0030] The first high-density closed-cell filling layer 7, the outer frame 1, and the fixing frame 3 are bonded together with adhesive.
[0031] The first high-closed-cell filling layer 7 and the second filling material 10 are bonded together by adhesive.
[0032] The first high-density closed-cell filling layer 7 and the second high-density closed-cell filling layer 9 have the same length and width;
[0033] Specifically, as shown in Figures 1, 3, and 4, the metal substrate is bonded to the first high-closed-cell filling layer 7, the outer frame 1, and the fixing frame 3 by adhesive bonding, and the first high-closed-cell filling layer 7 and the second filling material 10 are also bonded by adhesive bonding. This makes the structure more stable. Since the material of the first high-closed-cell filling layer 7 is flame-retardant polyurethane, and the material of the second high-closed-cell filling layer 9 is phenolic resin, and the length and width of the first high-closed-cell filling layer 7 and the second high-closed-cell filling layer 9 are the same, the closed-cell rate can be ≥90%, which can effectively isolate heat transfer.
[0034] Working Principle: In use, this invention firstly connects a first high-density closed-cell filling layer 7 to the front and rear ends of the outer frame 1 and the fixed frame 3, respectively. A second high-density closed-cell filling layer 9 is then fixedly connected to the outside of the first high-density closed-cell filling layer 7. A second filling material 10 is disposed inside the second high-density closed-cell filling layer 9, and a first filling material 8 is disposed inside the first high-density closed-cell filling layer 7. The first filling material 8 is aluminum hydroxide, and the second filling material 10 is expanded graphite. The aluminum hydroxide and expanded graphite, through chemical copolymerization or physical mixing, enhance flame retardancy. When exposed to fire, the closed-cell structure expands to form a dense carbonized layer, delaying the spread of flame and preventing the release of toxic fumes, making it safer and more flame-retardant during use. The flame retardancy is improved by using adhesive bonding between the first high-closed-cell filling layer 7, the outer frame 1, and the fixed frame 3, and between the first high-closed-cell filling layer 7 and the second filling material 10. This bonding of the metal substrate with the first high-closed-cell filling layer 7 makes the structure more stable. Since the material of the first high-closed-cell filling layer 7 is flame-retardant polyurethane, and the material of the second high-closed-cell filling layer 9 is phenolic resin, and the length and width of the first high-closed-cell filling layer 7 and the second high-closed-cell filling layer 9 are the same, the closed-cell rate can be ≥90%, which can effectively isolate heat transfer. When replacing the carved block 4, the positioning block 5 at the rear end of the fixed frame 3 can be inserted into the mounting groove 6 in the connecting frame 2 for fixation, making it convenient and quick to assemble and replace.
