[0035] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0036] First embodiment

[0037] like Figure 1 and Figure 2 As shown, the flame retardant composite floor of the first embodiment of the utility model comprises:

[0038] Floor profile 1, which is a metal profile;

[0039] The flame retardant layer includes a composite surface layer 2 laid on the top surface of the floor profile 1 and a heat conductive member 3 arranged on the composite surface layer 2. The heat conductive member 3 is used to absorb heat when the composite surface layer 2 is heated and diffuse the absorbed heat to the outside.

[0040] Specifically, the floor profile 1 in this embodiment is an aluminum alloy profile. Compared with other metal materials, aluminum alloy has higher thermal conductivity and is strong and lightweight. A flame retardant layer is laid on the top surface of the floor profile 1, and the flame retardant layer is formed by a composite surface layer 2 and a heat conductive component 3; wherein the composite surface layer 2 is a polymer material layer.

[0041] After adopting the above structure, when the composite surface layer 2 encounters a fire source and is heated, in addition to utilizing the aluminum alloy floor profile 1 to absorb the heat of the composite surface layer 2, the heat conductor 3 can also achieve the effect of absorbing the heat of the composite surface layer 2. Then, the floor profile 1 and the heat conductor 3 can diffuse the heat absorbed from the composite surface layer 2 to the outside. In this way, the heating rate of the composite surface layer 2 is slowed down, and the composite surface layer 2 is prevented from reaching above the ignition point after being heated. In this way, the purpose of flame retardancy is achieved.

[0042] Compared with the flame-retardant core material structure of the prior art in which a solid structure is inserted into the inner cavity of the floor profile 1, the flame-retardant layer in this embodiment is a layered structure, and its thickness and size are much lower than the flame-retardant core material. Therefore, the production cost of the composite floor of this embodiment can be greatly reduced. In addition, after using the flame-retardant layer as a flame-retardant means, the weight of the composite floor can be reduced, thereby facilitating transportation and installation, which is beneficial to reducing the workload of workers when laying the floor.

[0043] In order to facilitate the connection between the composite surface layer 2 and the heat conductive member 3, and at the same time ensure that there is sufficient heat exchange area between the composite surface layer 2 and the heat conductive member 3 to achieve the effect of quickly absorbing the heat of the composite surface layer 2, in this embodiment, the heat conductive member 3 is a heat conductive sheet fixed to the side of the composite surface layer 2 facing away from the floor profile 1; more specifically, the heat conductive sheet covers the composite surface layer 2.

[0044] After adopting the above structure, it is ensured that there is sufficient contact area between the heat conductor 3 and the composite surface layer 2, so that the heat conductor 3 can quickly absorb the heat of the composite surface layer 2, thereby achieving the purpose of cooling. In order to further improve the heat exchange efficiency and enable the heat conductor 3 to quickly absorb the heat of the composite surface layer 2, in this embodiment, the heat conductor 3 is preferably a metal heat conductor 3, and more specifically, the heat conductor 3 is an aluminum alloy heat conductive sheet.

[0045] In order to enhance the connection strength between the heat conducting member 3 and the composite surface layer 2 and prevent the two from being separated, in this embodiment, the heat conducting sheet is densely covered with connection holes 32. The shape, position and size of the connection holes 32 are not limited. During the production process of the flame retardant layer, the molten polymer material is laid on the heat conducting member 3, so that after the polymer material is cooled and formed, part of the material is formed in the connection holes 32, thereby enhancing the connection strength between the composite surface layer 2 and the heat conducting member 3.

[0046] Second embodiment

[0047] like Figure 3-Figure 6As shown, the flame-retardant composite floor of the second embodiment of the utility model is based on the first embodiment, and the difference is that the heat-conducting member 3 is a heat-conducting strip densely distributed on the composite surface layer 2.

[0048] Specifically, the top surface of the floor profile 1 is integrally formed with convex strips 12 on both sides, and the convex strips 12 extend along the length direction of the floor profile 1. The composite surface layer 2 is fixed to the top surface of the floor profile 1 and is located between the two convex strips 12. The heat conductor 3 is a metal heat conductor strip, and its length direction is parallel to the width direction of the floor profile 1. The heat conductor 3 is closely distributed along the length direction of the floor profile 1.

[0049] After adopting the above structure, the contact area between the heat conductive components 3 and the composite surface layer 2 is increased through the contact between the multiple closely distributed heat conductive components 3 and the composite surface layer 2, which is beneficial for the heat conductive components 3 to quickly absorb the heat of the composite surface layer 2 and avoid the composite surface layer 2 from heating up too quickly, thereby enhancing the flame retardant performance of the composite panel.

[0050] It should be noted that, in this embodiment, the heat conductive member 3 may also be distributed in other forms, and the length direction of the heat conductive member 3 is not limited. The densely distributed heat conductive member 3 can quickly absorb the heat of the composite surface layer 2, thereby achieving a flame retardant technical effect.

[0051] A further improvement is that the heat conducting element 3 protrudes from the side of the composite surface layer 2 facing away from the floor profile 1 .

[0052] Specifically, a groove 21 is provided on the top surface of the composite surface layer 2. The groove 21 is a through groove, extending along the width direction of the composite surface layer 2 and closely distributed along the length direction of the composite surface layer 2. The composite surface layer 2 corresponds to the heat conductor 3 one by one, and the lower part of the heat conductor 3 is adapted to the groove 21, and the upper part protrudes from the notch position.

[0053] After adopting the above structure, the side of the flame retardant layer away from the floor profile 1 is made rough, so that the anti-slip technical effect can be achieved, preventing passers-by from slipping when walking on the composite floor.

[0054] Third embodiment

[0055] like Figure 7-Figure 11 As shown, the flame-retardant composite floor of the third embodiment of the utility model is based on the second embodiment, and the difference is that the heat conducting member 3 is fixedly connected to the floor profile 1.

[0056] The heat conducting member 3 is fixedly connected to the floor profile 1, which facilitates the fixing of the composite surface layer 2. At the same time, heat exchange can be performed between the heat conducting member 3 and the floor profile 1, so that the two can absorb the heat of the composite surface layer 2 together and release the absorbed heat to the outside to delay the heating rate of the composite surface layer 2 and control the composite surface layer 2 below the ignition point as much as possible to enhance the flame retardant effect.

[0057] A further improvement is that the contact surface between the flame retardant layer and the floor profile 1 is a rough surface. After the contact surface between the two is a rough surface, the contact area between the flame retardant layer and the floor profile 1 is strengthened, and the flame retardant effect is improved on the basis of further strengthening the connection strength between the flame retardant layer and the floor profile 1.

[0058] In order to achieve a rough contact surface between the flame retardant layer and the floor profile 1 , protrusions 31 and depressions 11 are densely distributed between the flame retardant layer and the floor profile 1 .

[0059] Specifically, the top surface of the floor profile 1 is provided with three convex strips 12 which are evenly spaced and arranged side by side along its width direction, and a flame retardant layer is provided between two adjacent convex strips 12. The top surface of the floor profile 1 is also provided with a recess 11 located between two adjacent convex strips 12. The recess 11 is a groove-shaped structure extending along the width direction of the floor profile 1. The recesses 11 are evenly spaced along the length direction of the floor profile 1. In the flame retardant layer, the top surface of the composite surface layer 2 is provided with grooves 21 which are evenly spaced along its length direction, and the bottom of the groove 21 is provided with a strip hole 22. The heat conductor 3 is a heat conductive strip corresponding to the groove 21 one by one. The lower part of the heat conductive strip is matched with the groove 21, and the upper part protrudes from the top surface of the composite surface layer 2. The lower part of the heat conductive strip is also provided with a protrusion 31, which is penetrated through the inner side of the strip hole 22 and extends downward into the recess 11, and the end of the protrusion 31 is matched with the recess 11.

[0060] After adopting the above structure, the contact area between the heat conductor 3 and the floor profile 1 is increased by connecting the protrusions 31 and the recesses 11 one by one, thereby enhancing the heat exchange and connection strength between the two, and further ensuring that the composite surface layer 2 is firmly fixed to the top surface of the floor profile 1.

[0061] Fourth embodiment

[0062] like Fig.12 and Fig.11 As shown, the flame-retardant composite floor of the fourth embodiment of the present invention is based on the third embodiment, and the difference is that the heat-conducting member 3 is a heat-conducting net fixedly connected to the composite surface layer 2.

[0063] When the composite floor of this embodiment is produced, the heat-conducting mesh is first welded and fixed to the top surface of the floor profile 1, and then the molten polymer material is laid on the top surface of the floor profile 1. After the polymer material is cooled and formed into a composite surface layer 2, the composite surface layer 2 and the heat-conducting element 3 can be firmly connected to form a flame retardant layer.

[0064] The heat-conducting member 3 with a mesh structure can also greatly increase its contact area with the composite surface layer 2, thereby quickly absorbing the heat of the composite surface layer 2 and slowing down its temperature rise rate to achieve the purpose of flame retardancy.

[0065] Fifth embodiment

[0066] like Fig.13As shown, the flame-retardant composite floor of the fourth embodiment of the present invention is based on the first embodiment, but differs in that the heat-conducting element 3 is heat-conducting particles.

[0067] Specifically, the heat conductive member 3 is metal heat conductive particles. During the production process of the flame retardant layer of the composite floor of this embodiment, the heat conductive particles are added into the fused composite surface layer 2, so that a certain amount of metal particles are mixed inside the composite surface layer 2, and part of the metal particles are exposed to the top or bottom surface of the composite surface layer 2. After the composite surface layer 2 is cooled and solidified, the flame retardant layer can be obtained.

[0068] After the composite surface layer 2 is heated, the heat of the composite surface layer 2 can be absorbed by the heat-conductive particles, and the heat can be diffused to the outside through the heat-conductive particles on the top surface, or the heat can be transferred to the floor profile 1 by the metal particles on the bottom surface, and then the floor profile 1 can diffuse the heat, thereby delaying the temperature rise of the composite surface layer 2 and achieving a flame retardant effect.

[0069] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
