Description

Technical Field

[0001] The present application relates to the technical field of composite flooring, and more specifically, to a composite thermal insulation flooring. Background Art

[0002] Composite flooring is a composite flooring used for floor laying and decoration in building decoration. It is widely used in home decoration and commercial decoration and has good use effect. The existing composite flooring cannot meet people's needs, so a more convenient composite flooring is needed. After searching, the existing patent (publication number: CN208415828U) discloses a thermal insulation composite floor, including a patterned decorative plate, the upper outer surface of the patterned decorative plate is provided with a transparent wear-resistant layer, one side of the lower outer surface of the patterned decorative plate is provided with a mounting connection card column, the other side of the lower outer surface of the patterned decorative plate is provided with a mounting connection card slot, and the lower outer surface of the patterned decorative plate is fixedly installed with a base fixing plate, and the inner surface of the cavity insulation board is provided with multiple groups of insulation cavities. The thermal insulation composite floor described in the utility model is provided with a cavity insulation board, an insulation cavity, an anti-movement positioning pattern and a moisture-proof isolation layer, which can prevent the temperature of the room where the composite floor is installed from leaking from the ground, thereby achieving a heat preservation effect, preventing the floor from moving due to long-term use, eliminating the looseness caused by long-term use, and protecting the composite floor from moisture, ensuring that the composite floor will not be damaged due to moisture, having certain practicality, and bringing better prospects for use. In the process of realizing the utility model, the inventor found that the prior art has the following problems: The existing composite floor can effectively reduce the loss of heat to the ground when the floor is heated, but it also hinders the heat transfer from the floor upward. The heat encounters greater resistance during the transfer process and is difficult to reach the indoor floor quickly and efficiently. The area far away from the floor heats up slowly, forming a cold area, which makes it difficult for the temperature of the entire indoor space to reach the ideal state, thereby reducing the insulation effect of the floor. When the heating is temporarily stopped or the temperature drops, it is difficult to maintain a suitable temperature indoors. Therefore, a composite thermal insulation floor is proposed to solve the above problems. Summary of the invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present application provides a composite thermal insulation floor to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a composite thermal insulation floor, comprising a base reinforcement layer, a high thermal conductivity composite layer, a thermal conductive liquid pipe and a thermal conductive reinforcement layer, wherein the upper end surface of the base reinforcement layer is provided with a solid wood layer, the upper end surface of the solid wood layer is provided with an anti-wear and stain-resistant layer, the outer surface of the bottom of the solid wood layer is provided with a waterproof coating, 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; The upper end surface of the high thermal conductivity composite layer is provided with a limiting groove, and the limiting grooves are arranged in several groups. The heat transfer liquid pipes are arranged in several groups respectively, and adhesive fillers are arranged between the several groups of heat transfer liquid pipes and the limiting grooves. The inner cavity of the limiting groove, the thermal conductivity enhancement layer is arranged at the bottom of the high thermal conductivity composite layer, and the upper and lower end surfaces of the thermal conductivity enhancement layer are paved with metal copper wire mesh, and acrylic glue is coated between each group of the metal copper wire mesh and the thermal conductivity enhancement layer.

[0005] Preferably, the base reinforcement layer is made of glass fiber, and micropores are provided on the surface of the base reinforcement layer. The micropores are arranged in a plurality of groups, and the plurality of groups of micropores are distributed and arranged in an equidistant manner.

[0006] Preferably, a load-bearing central column is arranged at the center of the inner cavity of the load-bearing frame, and connecting support frames are arranged on both sides of the load-bearing central column.

[0007] Preferably, the connecting support frames are provided in a plurality of groups, and both ends of each group of the connecting support frames are respectively connected to the load-bearing frame and the load-bearing central column, and the connecting support frames in the plurality of groups are distributed and arranged in an equidistant manner.

[0008] Preferably, the edges of the upper and lower end surfaces of the load-bearing frame are respectively in contact with the base reinforcement layer and the high thermal conductivity composite layer, and the load-bearing frame, the connecting support frame and the load-bearing center column are all made of high-density fiber materials.

[0009] Preferably, the material of the wear-resistant and stain-resistant layer is ultraviolet curing paint, and the material of the waterproof coating is polyurethane.

[0011] Preferably, the adhesive filler is made of epoxy resin, and the thermal liquid pipe is fixed in the inner cavity of the limiting groove through the adhesive filler.

[0013] Technical effects and advantages of this application: 1. Compared with the existing technology, the composite thermal insulation floor forms an efficient thermal conduction network through the close combination of the thermal conductivity enhancement layer and the metal copper wire mesh. The grid structure of the metal copper wire mesh can quickly and evenly disperse the heat generated by the floor heating to various areas of the thermal conductivity enhancement layer. This uniform heat distribution greatly reduces the temperature gradient formed inside the thermal conductivity enhancement layer, reduces the loss and retention of heat during the conduction process, effectively retains the heat in the indoor space, and achieves an improvement in the thermal insulation effect.

[0014] 2. Compared with the prior art, the composite thermal insulation floor can store a large amount of heat energy when absorbing the heat from the floor heating due to its high specific heat capacity characteristics through the heat transfer oil in the heat transfer liquid pipe. When the indoor temperature reaches the set value, even if the heating of the floor heating fluctuates or is suspended, the heat stored in the heat transfer oil will be slowly released to continue to maintain the temperature of the indoor space, effectively slowing down the rate of loss of indoor heat to the external environment, reducing the heat exchange caused by temperature difference, thereby maintaining a relatively stable thermal environment indoors for a certain period of time, so that the indoor heat can be retained in the space for a longer period of time.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0021] As attached Figures 1 to 4 A composite thermal insulation floor is shown, comprising a base reinforcement layer 1, a high thermal conductivity composite layer 8, a thermal conduction liquid pipe 10 and a thermal conduction reinforcement layer 11, a solid wood layer 2 is arranged on the upper end surface of the base reinforcement layer 1, the base reinforcement layer 1 is made of glass fiber, a wear-resistant and stain-resistant layer 3 is arranged on the upper end surface of the solid wood layer 2, a waterproof coating 4 is arranged on the outer surface of the bottom of the solid wood layer 2, a load-bearing frame 5 is arranged below the base reinforcement layer 1, a load-bearing central column 6 is arranged at the center of the inner cavity of the load-bearing frame 5, connecting support frames 7 are arranged on both sides of the load-bearing central column 6, and the high thermal conductivity composite layer 8 is arranged below the load-bearing frame 5; A limiting groove 9 is provided on the upper end surface of the high thermal conductivity composite layer 8, and the limiting grooves 9 are arranged in several groups. The heat conducting liquid pipes 10 are arranged in several groups respectively, and adhesive fillers 901 are arranged between the several groups of heat conducting liquid pipes 10 and the limiting grooves 9. The inner cavity of the limiting groove 9, the thermal conductivity enhancement layer 11 is arranged at the bottom of the high thermal conductivity composite layer 8, and the upper and lower end surfaces of the thermal conductivity enhancement layer 11 are paved with metal copper wire mesh 12, and acrylic glue 13 is coated between each group of metal copper wire mesh 12 and the thermal conductivity enhancement layer 11.

[0022] Among them: the solid wood layer 2, as the surface in direct contact with the human body, provides a natural and comfortable foot feel, and 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 coating 4 to prevent the liquid from accidentally spilling from penetrating into the solid wood layer 2, avoiding deformation, cracking, mildew and other problems of the solid wood due to moisture. The basic reinforcement layer 1 made of glass fiber is below the solid wood layer 2. Due to its high strength and hardness, when heavy objects are placed on the floor or people walk, it can effectively evenly bear the pressure and disperse it to the load-bearing frame 5 below. The load-bearing frame 5 serves as the edge support of the overall structure and bears most of the lateral pressure; the load-bearing central column 6 is in the center position and bears the main vertical downward pressure, while the connecting support frame 7 plays the role of connection and auxiliary support. They work together to make the pressure evenly distributed on the entire structure. The high thermal conductivity composite layer 8 and the thermal oil combination of the thermal liquid pipe 10 inside it form an efficient heat conduction system. The high specific heat capacity of the thermal oil and the heat transfer effect in the pipe The good fluidity inside enables heat to be quickly and evenly transferred and stored in the layer, which accelerates the heating speed of the indoor floor, reduces the waiting time for warmth, and can also play a buffering role when the heating supply fluctuates to stabilize the indoor temperature. The heat-conducting liquid pipe 10 fills the gap with the limiting groove 9 by bonding the filler 901. Then the thermally conductive reinforcing layer 11, as the key layer directly contacting the floor heating heat source, has good thermal conductivity itself and can quickly absorb the heat generated by the floor heating and transfer it upward. The metal copper wire mesh laid on the upper and lower end surfaces further enhances the heat conduction effect. The high thermal conductivity of the metal copper wire mesh 12 enables heat to be quickly conducted along the copper wire. The grid structure can evenly disperse the heat to various parts of the thermally conductive reinforcing layer 11, avoiding uneven conduction caused by local overheating or heat concentration. The acrylic glue 13 ensures that the metal copper wire mesh 12 is tightly combined with the thermally conductive reinforcing layer 11, while having a certain flexibility, which can adapt to the thermal expansion and contraction deformation of the metal mesh 12 and the thermally conductive reinforcing layer 11 when the temperature changes, and prevent the separation or cracking between the materials from affecting the heat conduction efficiency. Example

[0023] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working method. Figures 1 to 4 As shown, see the following description for details: As a preferred embodiment, the base reinforcement layer 1 is made of glass fiber, and micropores 101 are provided on the surface of the base reinforcement layer 1. The micropores 101 are arranged in several groups, and the several groups of micropores 101 are distributed and arranged at equal intervals; further, the presence of the micropores 101 helps to optimize the distribution of heat in the base reinforcement layer. Since the micropores 101 can serve as tiny channels for heat, the heat can be better diffused laterally inside the base reinforcement layer 1. When the heat from local heating is conducted to the base reinforcement layer 1, the heat will diffuse to the surroundings through the micropores 101, thereby avoiding local accumulation of heat.

[0024] As a preferred embodiment, several groups of connecting support frames 7 are provided, and the two ends of each group of connecting support frames 7 are respectively connected to the load-bearing frame 5 and the load-bearing center column 6, and the several groups of connecting support frames 7 are arranged in an equidistant manner; further, several groups of connecting support frames 7 distributed in an equidistant manner can more evenly share the pressure from the upper floor structure and heavy objects. When the heavy object is placed on the floor, the pressure is transmitted to the load-bearing center column 6 and the load-bearing frame 5 through the solid wood layer 2 and the base reinforcement layer 1, and the load-bearing center column 6 disperses the pressure to the connecting support frames 7, and the weight can be evenly distributed.

[0025] As a preferred embodiment, the edges of the upper and lower end surfaces of the load-bearing frame 5 are respectively in contact with the base reinforcement layer 1 and the high thermal conductivity composite layer 8, and the load-bearing frame 5, the connecting support frame 7 and the load-bearing center column 6 are all made of high-density fiber materials; further, since the load-bearing frame 5, the connecting support frame 7 and the load-bearing center column 6 are all made of high-density fiber materials, this material itself has a certain thermal conductivity, and a coherent heat conduction channel is formed in the entire floor structure. When the heat generated by 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 center column 6.

[0026] As a preferred embodiment, the material of the wear-resistant and stain-resistant layer 3 is UV-curing paint, and the material of the waterproof coating 4 is polyurethane; further, the wear-resistant and stain-resistant layer 3 of the UV-curing paint can be quickly cured to form a hard and wear-resistant surface after being irradiated by ultraviolet rays, thereby preventing people from walking frequently and moving furniture and possibly causing wear on the floor. The waterproof coating 4 made of polyurethane has good waterproof properties. When liquid penetrates into the solid wood layer 2 through the joint gap, the waterproof coating 4 made of polyurethane can effectively prevent moisture from penetrating from the side and bottom.

[0027] As a preferred embodiment, the high thermal conductivity composite layer 8 is a blend of carbon fiber, ceramic particles and epoxy resin materials, and the inner cavity of the thermal liquid pipe 10 is filled with thermal oil; further, the carbon fiber, ceramic particles and epoxy resin materials are blended to form a stable high thermal conductivity composite layer 8, thereby ensuring the mechanical strength and integrity of the composite layer, and being able to maintain heat conduction while protecting the internal thermal liquid pipe 10 to stably perform its thermal conductivity function in its limiting groove 9.

[0028] As a preferred embodiment, the adhesive filler 901 is made of epoxy resin, and the thermal liquid pipe 10 is fixed in the inner cavity of the limiting groove 9 by the adhesive filler 901; further, the adhesive filler 901 made of epoxy resin has excellent bonding ability, and can form a firm connection between the thermal liquid pipe 10 and the limiting groove 9. The epoxy resin can well infiltrate and fill the gap between the surface of the thermal liquid pipe 10 and the limiting groove 9, and form 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 in the inner cavity of the limiting groove 9.

[0029] As a preferred embodiment, the thermally conductive enhancement layer 11 is made of ceramic fiber, and spaces for installing the metal copper wire mesh 12 are provided on the upper and lower ends of the thermally conductive enhancement layer 11; further, the ceramic fiber itself has good thermal conductivity and can effectively conduct the heat generated by the floor heating upward, and its internal fiber structure forms an intricate thermal conduction channel, and heat can be quickly transferred along the contact points between these fibers. The thermally conductive enhancement layer 11 can quickly absorb heat from the bottom and transfer it to the high thermal conductivity composite layer 8, reducing the retention of heat during the conduction process and improving the thermal conduction efficiency of the entire floor. The spaces for installing the metal copper wire mesh 12 provided at the upper and lower ends allow the metal copper wire mesh 12 to be tightly combined with the thermally conductive enhancement layer 11.

[0030] As a preferred embodiment, the metal copper wire mesh 12 is arranged in a grid-like distribution, and two groups of metal copper wire meshes 12 are bonded to the inner cavity of the upper and lower end surfaces of the thermal conductivity enhancement layer 11 by acrylic glue 13; further, the metal copper wire mesh 12 is arranged in a grid-like distribution, which greatly increases the contact area with the thermal conductivity enhancement layer 11. When heat is transferred from the floor heating to the thermal conductivity enhancement layer 11, each copper wire of the metal copper wire mesh 12 becomes a heat conduction channel, and the heat can be diffused through the copper wire.

[0031] The working process of the present application is as follows: first, the anti-wear and anti-fouling layer 3 of the UV-curing paint on the surface of the solid wood layer 2 forms a hard and wear-resistant surface after being irradiated by ultraviolet rays, which can resist the friction of the soles of shoes, table and chair legs, etc. on the floor surface. The waterproof coating 4 formed by the polyurethane material on the bottom and side of the solid wood layer 2 can effectively prevent moisture from penetrating into the solid wood layer 2 from the gap. The load-bearing central column 6 is in the central position and bears the main vertical pressure. The connecting support frame 7 disperses the pressure from the load-bearing central column 6 to the load-bearing frame 5; After the local heating is turned on, the heat is first transferred to the thermally conductive enhancement layer 11. The ceramic fiber material of the thermally conductive enhancement layer 11 itself has good thermal conductivity, and its internal fiber structure forms a thermal conduction channel; the metal copper wire mesh 12 arranged in a grid shape is laid on the upper and lower end surfaces, and the metal copper wire mesh 12 can be firmly bonded to the space on the upper and lower end surfaces of the thermally conductive enhancement layer 11 through acrylic glue 13. Due to the high thermal conductivity and large-area contact of the metal copper wire mesh 12, the heat can be quickly diffused in the horizontal direction and conducted through the copper wire, and cooperate with the ceramic fiber to efficiently transfer the heat from the bottom to the top. The heat is transferred from the thermally conductive enhancement layer 11 to the high thermal conductivity composite layer 8. The high thermal conductivity composite layer 8 is a mixture of carbon fiber, ceramic particles and epoxy resin materials. Heat is quickly transferred in this composite layer through the contact points between the materials, and because the thermal liquid pipe 10 inside the limiting groove 9 is filled with thermal conductive liquid The adhesive filler 901 made of oil and epoxy resin can well infiltrate and fill the gap between the surface of the heat transfer liquid pipe 10 and the limit groove 9, and form a tight bonding interface after curing. The heat transfer oil has a high specific heat capacity and can absorb and store a large amount of heat, thereby evenly diffusing the heat in the high thermal conductivity composite layer 8. Subsequently, since the load-bearing frame 5, the connecting support frame 7 and the load-bearing center column 6 are all made of high-density fiber materials, this material itself has a certain thermal conductivity, and a coherent heat transfer channel is formed in the entire floor structure, which conducts heat to the upper base reinforcement layer 1. The heat is transferred to the solid wood layer 2 through the base reinforcement layer 1, so that the solid wood layer 2 is heated. When the indoor temperature reaches the set value, even if the heating of the floor heating fluctuates or is suspended, the heat stored in the heat transfer oil will be slowly released to continue to maintain the temperature of the indoor space. The above is the working principle of this composite thermal insulation floor.
