[0017] The following further details the specific embodiments of the present utility model. It should be understood that the description of the embodiments of the present utility model herein is not intended to limit the protection scope of the present utility model.
[0018] As Figures 1 to 2 shown, it is a schematic structural view of the porous soundproof floor provided by the present utility model. The porous soundproof floor includes a layer of base layer 10, a layer of aluminum foam core layer 20, a layer of decorative layer 30, and a layer of wear-resistant layer 40 arranged in sequence. It can be imagined that the porous soundproof floor further includes other functional modules, such as an adhesive layer provided at the bottom of the base layer 10, etc., which are well-known technologies to those skilled in the art and will not be elaborated herein.
[0019] The base layer 10 is composed of a single layer of solid wood, such as poplar, eucalyptus, or beech. Among them, poplar and eucalyptus have soft textures and good sound absorption effects, while beech is hard and has good support. In this embodiment, the base layer 10 is a poplar wood board. Since the structure of poplar is relatively loose, it can adsorb a certain amount of noise, and poplar grows fast and has a low price, so it is economically beneficial to use it as the base layer 10.
[0020] Connection parts 11 are provided around the base layer 10. The connection parts 11 include top connection parts 111 and bottom connection parts 112. The top connection parts 111 and the bottom connection parts 112 are symmetrically arranged at both ends of the base layer 10. Two top connection parts 111 and two bottom connection parts 112 are respectively provided around each base layer 10.
[0021] A convex strip 113 is provided at the bottom of the top connection part 111, and a groove 114 corresponding to the convex strip 113 is provided at the top of the bottom connection part 112. The convex strip 113 of the top connection part 111 is clamped in the groove 114 to make the adjacent base layers 10 fit together. The lengths of the convex strip 113 and the groove 114 are respectively the same as the corresponding side lengths of the base layer 10, so as to ensure the stability after mutual fastening.
[0022] A pin 115 is inserted between the top connecting part 111 and the bottom connecting part 112, thereby strengthening the firmness of the connection between the top connecting part 111 and the bottom connecting part 112.
[0023] The aluminum foam core layer 20 is made by bonding one or two of aluminum foam plates and solid wood or artificial boards. The aluminum foam plate of the aluminum foam core layer 20 and the solid wood or artificial board are cold-pressed, the cold-pressing pressure is 0.4 - 0.8 MPa, and the time is 0.5 - 3.5 h. A plurality of air holes 21 are distributed in the aluminum foam plate of the aluminum foam core layer 20. The diameter of the air holes 21 is 0.1 - 1.5 mm, so that noise can be absorbed through the air holes 21 without damaging the structural strength of the aluminum foam core layer 20.
[0024] The air holes 21 are distributed inside and on the surface of the aluminum foam core layer 20, and the air holes 21 are distributed at multiple positions, which can ensure good sound absorption effect.
[0025] The thickness of the aluminum foam core layer 20 is at least 60% - 80% of the total thickness of the floor. Since the base layer 10 is made of poplar wood, its material is loose and the support strength is insufficient. Therefore, the aluminum foam core layer 20 with sufficient thickness can not only play a sound absorption effect, but also play a supporting role. In this embodiment, the thickness of the aluminum foam core layer 20 is 8 - 15 mm to meet the support strength and thickness required for ordinary household floors.
[0026] The aluminum foam core layer 20 is mixed with nano-carbon particles, thereby improving the strength of the aluminum foam core layer 20.
[0027] The decorative layer 30 is arranged on the surface of the aluminum foam core layer 20. The decorative layer 30 is a thin sheet, and its material is polyester fiber or paper. The decorative layer 30 is laid on the surface of the aluminum foam core layer 20, which can not only cover the air holes 21 on the surface of the aluminum foam core layer 20, but also play a decorative effect. Graphics are printed on the surface of the decorative layer 30, thereby increasing the beauty of the floor.
[0028] The wear-resistant layer 40 is used to protect the decorative layer 30 from being worn. The wear-resistant layer 40 is made of a transparent material.
[0029] The aluminum foam core layer 20 is hot-pressed and bonded with the base layer 10 and the decorative layer 30, the pressure is 0.6 - 1.2 MPa, and the time is 5 - 30 min, so that the connection between the layers of the board is tight.
[0030] Compared with the prior art, the porous soundproof floor provided by the utility model increases the strength of the floor by arranging a layer of aluminum foam core layer 20. A plurality of air holes 21 are arranged in the aluminum foam core layer 20, which can not only adsorb noise, but also the structure of the air holes 21 can produce slight deformation to buffer vibration during vibration, improving the comfort when the user steps on it.
[0031] The above are only the preferred embodiments of the utility model and are not used to limit the protection scope of the utility model. Any modifications, equivalent replacements or improvements within the spirit of the utility model are covered within the scope of the claims of the utility model.
