Description

Technical Field

[0001] This application relates to the field of composite flooring technology, and more specifically, to a composite thermal insulation floor. Background Technology

[0002] Composite flooring is a type of flooring used for flooring and decoration in building decoration. It is widely used in home decoration and commercial decoration and has good performance. However, existing composite flooring cannot meet people's needs, so there is a need for more convenient composite flooring.

[0003] A search revealed an existing patent (publication number: CN208415828U) that discloses an insulated composite floor, comprising a patterned decorative panel. The upper outer surface of the patterned decorative panel has a transparent wear-resistant layer. One side of the lower outer surface of the patterned decorative panel has a mounting connector post, and the other side has a mounting connector groove. A base fixing plate is fixedly installed on the lower outer surface of the patterned decorative panel. The inner surface of the cavity insulation panel has multiple sets of insulation cavities. This utility model discloses an insulated composite floor, which includes a cavity insulation panel, insulation cavities, an anti-movement positioning pattern, and a moisture-proof isolation layer. It can prevent heat leakage from the floor in the room where the composite floor is installed, thus achieving an insulation effect. It can prevent the floor from shifting after prolonged use, eliminating loosening caused by long-term use. It also provides moisture protection for the composite floor, ensuring that it will not be damaged by moisture. It has practicality and a better future application prospect. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing composite flooring, while effectively reducing heat loss to the floor when underfloor heating is on, also hinders heat conduction upwards from the underfloor heating system. The heat encounters significant resistance during transmission, making it difficult to reach the indoor floor quickly and efficiently. Areas far from the floor heat up slowly, forming cold zones. As a result, the temperature of the entire indoor space is difficult to reach an ideal state, thus reducing the insulation effect of the flooring. When heating is temporarily stopped or the temperature drops, it is difficult to maintain a suitable indoor temperature.

[0005] Therefore, a composite thermal insulation floor is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this application provides a composite thermal insulation floor to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this application provides the following technical solution: a composite thermal insulation floor, comprising a base reinforcement layer, a high thermal conductivity composite layer, a thermally conductive liquid pipe, and a thermally conductive reinforcement layer. A solid wood layer is provided on the upper surface of the base reinforcement layer, and an anti-wear and stain-resistant layer is provided on the upper surface of the solid wood layer. A waterproof coating is provided on the outer surface of the bottom of the solid wood layer. A load-bearing frame is provided below the base reinforcement layer, and the high thermal conductivity composite layer is provided below the load-bearing frame.

[0008] The upper surface of the high thermal conductivity composite layer is provided with a limiting groove, and several sets of the limiting groove are provided. The heat conduction liquid pipes are respectively provided in several sets. An adhesive filler is provided between each set of heat conduction liquid pipes and the limiting groove. The inner cavity of the limiting groove is provided with a thermally conductive reinforcement layer at the bottom of the high thermal conductivity composite layer. The upper and lower surfaces of the thermally conductive reinforcement layer are covered with copper wire mesh. Each set of copper wire meshes is coated with acrylic adhesive between itself and the thermally conductive reinforcement layer.

[0009] Preferably, the base reinforcement layer is made of glass fiber, and the surface of the base reinforcement layer is provided with micropores. The micropores are arranged in several groups, and the several groups of micropores are distributed and arranged at equal intervals.

[0010] Preferably, a load-bearing central column is provided at the center of the inner cavity of the load-bearing frame, and connecting support frames are provided on both sides of the load-bearing central column.

[0011] Preferably, the connecting support frame is provided in several groups, and the two ends of each group of the connecting support frame are respectively connected to the load-bearing frame and the load-bearing central column, and the several groups of connecting support frames are distributed and arranged at equal intervals.

[0012] Preferably, the edges of the upper and lower end faces of the load-bearing frame abut against the base reinforcement layer and the high thermal conductivity composite layer, respectively, and the load-bearing frame, the connecting support frame and the load-bearing central column are all made of high-density fiber material.

[0013] Preferably, the wear-resistant and stain-resistant layer is made of UV-cured paint, and the waterproof coating is made of polyurethane.

[0014] Preferably, the inner cavity of the heat-conducting fluid pipe is filled with heat-conducting oil.

[0015] Preferably, the adhesive filler is made of epoxy resin, and the heat-conducting liquid pipe is fixed to the inner cavity of the limiting groove by the adhesive filler.

[0016] Preferably, the thermally conductive reinforcement layer is made of ceramic fiber, and both the upper and lower surfaces of the thermally conductive reinforcement layer have spaces for the installation of the metal copper wire mesh.

[0017] Preferably, the copper wire mesh is arranged in a grid pattern, and both sets of copper wire mesh are bonded to the inner cavity of the upper and lower end faces of the thermally conductive reinforcement layer by the acrylic adhesive.

[0018] The technical effects and advantages of this application are as follows:

[0019] 1. Compared with existing technologies, this composite thermal insulation floor forms a highly efficient thermal network through the tight combination of the thermally conductive reinforcement layer and the metal copper wire mesh. The mesh structure of the metal copper wire mesh can quickly and evenly distribute the heat generated by the underfloor heating to various areas of the thermally conductive reinforcement layer. This uniform heat distribution greatly reduces the temperature gradient formed inside the thermally conductive reinforcement layer, reduces the loss and retention of heat during the conduction process, effectively retains heat in the indoor space, and improves the thermal insulation effect.

[0020] 2. Compared with existing technologies, this composite thermal insulation floor uses the heat-conducting oil in the heat-conducting liquid pipe, which has a high specific heat capacity, to store a large amount of heat energy when absorbing heat from the underfloor heating. When the indoor temperature reaches the set value, even if the heating of the underfloor heating fluctuates or is interrupted, the heat stored in the heat-conducting oil will be slowly released to continue to maintain the temperature of the indoor space. This effectively slows down the rate at which indoor heat is lost to the outside environment and reduces heat exchange caused by temperature differences. As a result, a relatively stable thermal environment is maintained indoors for a certain period of time, allowing indoor heat to be retained in the space for a longer period of time.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0027] As attached Figures 1 to 4 The composite thermal insulation floor shown includes a base reinforcement layer 1, a high thermal conductivity composite layer 8, a thermally conductive liquid pipe 10, and a thermally conductive reinforcement layer 11. A solid wood layer 2 is provided on the upper surface of the base reinforcement layer 1. The base reinforcement layer 1 is made of fiberglass. An anti-wear and stain-resistant layer 3 is provided on the upper surface of the solid wood layer 2. A waterproof coating 4 is provided on the outer surface of the bottom of the solid wood layer 2. A load-bearing frame 5 is provided below the base reinforcement layer 1. A load-bearing central column 6 is provided at the center of the inner cavity of the load-bearing frame 5. Connecting support frames 7 are provided on both sides of the load-bearing central column 6. The high thermal conductivity composite layer 8 is provided below the load-bearing frame 5.

[0028] A limiting groove 9 is provided on the upper end face of the high thermal conductivity composite layer 8. Several sets of limiting grooves 9 are provided, and heat conduction liquid pipes 10 are respectively provided in several sets. Adhesive filler 901 is provided between each set of heat conduction liquid pipes 10 and the limiting groove 9. The inner cavity of the limiting groove 9 is provided with a thermally conductive reinforcing layer 11 at the bottom of the high thermal conductivity composite layer 8. Metal copper wire mesh 12 is laid on both the upper and lower end faces of the thermally conductive reinforcing layer 11. Acrylic ester adhesive 13 is coated between each set of metal copper wire mesh 12 and the thermally conductive reinforcing layer 11.

[0029] Among them: the solid wood layer 2, as the surface in direct contact with the human body, provides a natural and comfortable feel underfoot; the wear-resistant and stain-resistant layer 3 effectively protects the solid wood layer 2 from daily wear, scratches, and stains; the bottom and sides of the solid wood layer 2 are coated with a waterproof layer 4 to prevent accidental spills from penetrating into the solid wood layer 2, avoiding problems such as deformation, cracking, and mold growth due to moisture; the fiberglass reinforcement layer 1 is located below the solid wood layer 2; due to its high strength and hardness, it can effectively and evenly distribute the pressure when heavy objects are placed on the floor or when people walk on it, and distribute it to the load-bearing frame 5 below. The load-bearing frame 5, as the edge support of the overall structure, bears most of the lateral pressure; the load-bearing central column 6 is located in the center and bears the main vertical downward pressure, while the connecting support frame 7 plays a connecting and auxiliary support role. They work together to ensure that the pressure is evenly distributed throughout the structure; the high thermal conductivity composite layer 8, with its internal heat-conducting liquid pipe 10 and heat-conducting oil combination, forms a highly efficient heat conduction system. The high specific heat capacity of the heat-conducting oil and its properties within the pipe... The good fluidity within the layer allows heat to be transferred and stored quickly and evenly, accelerating the heating rate of the indoor floor, reducing the waiting time for warmth, and also acting as a buffer during heating fluctuations to stabilize the indoor temperature. The heat-conducting liquid pipe 10 fills the gap between itself and the limiting groove 9 with adhesive filler 901. Subsequently, the heat-conducting reinforcement layer 11, as a key layer that directly contacts the underfloor heating heat source, has good thermal conductivity and can quickly absorb the heat generated by the underfloor heating and transfer it upwards. The metal copper wire mesh laid on the upper and lower end faces further enhances the heat conduction effect. The high thermal conductivity of the metal copper wire mesh 12 allows heat to be conducted quickly along the copper wires. The mesh structure can evenly distribute heat to all parts of the heat-conducting reinforcement layer 11, avoiding uneven conduction caused by local overheating or heat concentration. The acrylic adhesive 13 ensures that the metal copper wire mesh 12 and the heat-conducting reinforcement layer 11 are tightly bonded, while having a certain degree of flexibility, which can adapt to the thermal expansion and contraction deformation of the metal mesh 12 and the heat-conducting reinforcement layer 11 when the temperature changes, preventing the heat conduction efficiency from being affected by the separation or cracking between the materials. Example

[0030] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0031] In a preferred embodiment, the base reinforcement layer 1 is made of glass fiber, and micropores 101 are formed on the surface of the base reinforcement layer 1. Several groups of micropores 101 are arranged in an equidistant manner. Furthermore, the presence of micropores 101 helps to optimize the distribution of heat in the base reinforcement layer. Since the micropores 101 can act as tiny channels for heat, heat can be better diffused laterally inside the base reinforcement layer 1. When the heat from the ground heating is conducted to the base reinforcement layer 1, the heat will diffuse to the surroundings through the micropores 101, avoiding heat accumulation in local areas.

[0032] In a preferred embodiment, the connecting support frame 7 is provided in several groups. The two ends of each group of connecting support frame 7 are connected to the load-bearing frame 5 and the load-bearing central column 6, respectively. The several groups of connecting support frames 7 are distributed at equal intervals. Furthermore, the several groups of equally spaced connecting support frames 7 can more evenly distribute the pressure from the floor structure above and the heavy objects. When the heavy objects are placed on the floor, the pressure is transmitted to the load-bearing central column 6 and the load-bearing frame 5 through the solid wood layer 2 and the base reinforcement layer 1. The load-bearing central column 6 then distributes the pressure to the connecting support frame 7, and the weight can be evenly distributed.

[0033] In a preferred embodiment, the edges of the upper and lower ends of the load-bearing frame 5 abut against the base reinforcement layer 1 and the high thermal conductivity composite layer 8, respectively. The load-bearing frame 5, the connecting support frame 7, and the load-bearing central column 6 are all made of high-density fiber material. Furthermore, since the load-bearing frame 5, the connecting support frame 7, and the load-bearing central column 6 are all made of high-density fiber material, this material itself has a certain thermal conductivity, forming a continuous heat conduction channel in the entire floor structure. When the heat generated by the floor heating is conducted upward from the high thermal conductivity composite layer 8, the heat can be further conducted to the base reinforcement layer 1 through the load-bearing frame 5, the connecting support frame 7, and the load-bearing central column 6.

[0034] As a preferred embodiment, the wear-resistant and stain-resistant layer 3 is made of UV-cured paint, and the waterproof coating 4 is made of polyurethane. Furthermore, after being irradiated with ultraviolet light, the wear-resistant and stain-resistant layer 3 of the UV-cured paint can quickly cure to form a hard and wear-resistant surface, preventing wear and tear on the floor that may be caused by frequent foot traffic and furniture movement. The waterproof coating 4 of polyurethane has good waterproof performance. When liquid seeps into the solid wood layer 2 through the joint gaps, the polyurethane waterproof coating 4 can effectively prevent moisture from seeping in from the sides and bottom.

[0035] In a preferred embodiment, the high thermal conductivity composite layer 8 is a blend of carbon fiber, ceramic particles and epoxy resin, and the inner cavity of the heat-conducting liquid pipe 10 is filled with heat-conducting oil; furthermore, the blending of carbon fiber, ceramic particles and epoxy resin forms a stable high thermal conductivity composite layer 8, thereby ensuring the mechanical strength and integrity of the composite layer, and can maintain heat conduction while protecting the internal heat-conducting liquid pipe 10 to stably perform its heat conduction function within its limiting groove 9.

[0036] In a preferred embodiment, the adhesive filler 901 is made of epoxy resin, and the heat transfer fluid pipe 10 is fixed to the inner cavity of the limiting groove 9 by the adhesive filler 901. Furthermore, the epoxy resin adhesive filler 901 has excellent bonding ability and can form a firm connection between the heat transfer fluid pipe 10 and the limiting groove 9. The epoxy resin can well wet and fill the gap between the surface of the heat transfer fluid pipe 10 and the limiting groove 9, forming a tight bonding interface after curing. Even when subjected to thermal expansion and contraction, floor vibration or other external forces, it can still be firmly fixed to the inner cavity of the limiting groove 9.

[0037] In a preferred embodiment, the thermally conductive reinforcing layer 11 is made of ceramic fiber, and spaces for installing the copper wire mesh 12 are provided at both the upper and lower ends of the thermally conductive reinforcing layer 11. Furthermore, ceramic fiber itself has good thermal conductivity, which can effectively conduct the heat generated by the underfloor heating upwards. Its internal fiber structure forms a complex thermal conduction channel, and heat can be quickly transferred along the contact points between these fibers. The thermally conductive reinforcing layer 11 can quickly absorb heat from the bottom and transfer it to the high thermal conductivity composite layer 8, reducing the heat retention during the conduction process and improving the overall thermal conductivity efficiency of the floor. The spaces for installing the copper wire mesh 12 at both the upper and lower ends allow the copper wire mesh 12 to be tightly bonded to the thermally conductive reinforcing layer 11.

[0038] In a preferred embodiment, the copper wire mesh 12 is arranged in a grid pattern, and both sets of copper wire mesh 12 are bonded to the inner cavity of the upper and lower end faces of the thermally conductive reinforcement layer 11 by acrylic adhesive 13. Furthermore, the grid pattern arrangement of the copper wire mesh 12 greatly increases the contact area with the thermally conductive reinforcement layer 11. When heat is transferred from the underfloor heating to the thermally conductive reinforcement layer 11, each copper wire of the copper wire mesh 12 becomes a channel for heat conduction, and heat can diffuse through the copper wire.

[0039] The working process of this application is as follows: First, the wear-resistant and stain-resistant layer 3 of the UV-cured paint on the surface of the solid wood layer 2 forms a hard and wear-resistant surface after being irradiated by ultraviolet light, which can resist the friction of shoe soles, table and chair legs, etc. on the floor surface. The waterproof coating 4 formed by the polyurethane material on the bottom and sides of the solid wood layer 2 can effectively prevent moisture from seeping into the solid wood layer 2 from the gaps. The load-bearing central column 6 is located in the center and bears the main vertical pressure. The connecting support frame 7 distributes the pressure from the load-bearing central column 6 to the load-bearing frame 5.

[0040] When the local heating is turned on, heat is first transferred to the thermally conductive reinforcement layer 11. The ceramic fiber material of the thermally conductive reinforcement layer 11 itself has good thermal conductivity, and its internal fiber structure forms thermal conduction channels. Metal copper wire mesh 12, arranged in a grid pattern on the upper and lower end faces, can be firmly bonded to the space between the upper and lower end faces of the thermally conductive reinforcement layer 11 using acrylic adhesive 13. Due to the high thermal conductivity and large contact area of ​​the metal copper wire mesh 12, heat can quickly diffuse horizontally and be conducted through the copper wires. Working synergistically with the ceramic fibers, heat is efficiently transferred from the bottom to the top. The heat is then transferred from the thermally conductive reinforcement layer 11 to the high thermal conductivity composite layer 8. The high thermal conductivity composite layer 8 is composed of a blend of carbon fiber, ceramic particles, and epoxy resin. Heat is rapidly transferred in this composite layer through the contact points between the materials. Furthermore, the thermally conductive liquid pipe 10 inside the limiting groove 9 is filled with thermally conductive liquid... The adhesive filler 901, made of oil and epoxy resin, can effectively impregnate and fill the gaps between the surface of the heat-conducting liquid pipe 10 and the limiting groove 9, forming a tight bonding interface after curing. The heat-conducting oil has a high specific heat capacity, which can absorb and store a large amount of heat, thereby evenly dispersing the heat within the high thermal conductivity composite layer 8. Subsequently, since the load-bearing frame 5, connecting support frame 7, and load-bearing central column 6 are all made of high-density fiber material, which itself has a certain thermal conductivity, a continuous heat-conducting channel is formed in the entire floor structure, conducting heat to the upper base reinforcement layer 1. The heat is transferred through the base reinforcement layer 1 to the solid wood layer 2, causing the solid wood layer 2 to heat up. When the indoor temperature reaches the set value, even if the underfloor heating fluctuates or is paused, the heat stored in the heat-conducting oil will be slowly released to continue maintaining the indoor temperature. The above is the working principle of this composite thermal insulation floor.
