Description

TECHNICAL FIELD

[0001] The utility model relates to building energy conservation and sound insulation technical field, especially in a kind of nano modified GPS flexible thermal insulation and sound insulation pad structure. BACKGROUND

[0002] In the field of building construction, especially in the state of delivery of raw commercial housing, the ground flatness is a common problem. In the traditional manufacturing process of modified GPS flexible thermal insulation and sound insulation pad, the GPS plate is toughened by compression or rolling, and then plastic cutting is performed to form a plane structure with high flatness on the upper and lower surfaces, and reinforcing cloth is pasted on the upper surface to reduce the transmission of floor impact sound. However, this high flatness design faces many challenges in actual installation process. Due to the undulating ground surface, the sound insulation pad is prone to have height difference after installation, resulting in poor overall performance, unsatisfactory installation effect and other problems. In addition, the existing GPS plate has the problem of insufficient functional compatibility in design: the flat plate structure has good sound insulation performance, but the pressure bearing capacity is weak; while the slotted plate has strong pressure bearing capacity, but it is difficult to achieve ideal sound insulation effect, and the balance between sound insulation and pressure bearing cannot achieve maximum compatibility.

[0003] In the application scenario of floating floor slab, the thermal insulation and sound insulation pad is usually pasted with reinforcing cloth (such as non-woven fabric, glass fiber mesh or other fiber fabric) on the upper surface by using film agent to enhance its strength. However, when using ground heating system in cold and severe cold areas, especially in wet floor heating construction, it is necessary to lay another ground heating reflective film on the thermal insulation and sound insulation pad. As an auxiliary thermal insulation material, the reflective film indirectly improves the overall thermal resistance by reducing downward heat transfer. However, in the concrete filling system, when the reflective film is used with metal mesh, the operation of fixing the heating pipe is easy to cause the reflective film to be punctured. Once the reflective film is damaged, the backfilling concrete will leak and form a hard connection with the floor slab, increasing the vibration transmission and significantly reducing the sound insulation efficiency of the sound insulation plate. At the same time, the performance of the existing sound insulation pad in terms of corrosion resistance, aging resistance, puncture resistance and high temperature resistance still needs to be further improved. Therefore, how to effectively solve the above problems and optimize the functional compatibility, construction convenience and physical and chemical properties of the sound insulation pad has become a technical problem to be solved. UTILITY MODEL CONTENTS

[0004] The utility model aims to provide a kind of nano modified GPS flexible thermal insulation and sound insulation pad structure, solve the problem mentioned in the background art.

[0005] The utility model discloses a kind of nano-modified GPS flexible heat-insulating and sound-insulating mat structures, and the bottom of the nano-modified GPS flexible heat-insulating and sound-insulating mat structure adopts specially designed pressure-bearing damping structure, and its upper surface is covered with flexible heat-reflective film.The pressure-bearing damping structure is composed of three parts: a part is the lowest point, directly contacts with ground, and bears main static load;b part is located in middle height, and under the action of self-weight of floating plate and finish layer, it is locally subsided instantaneously and stabilized, and under the action of dynamic load, it is continuously or intermittently contacted with ground with load change, and the ground contact area, dynamic stiffness and bearing capacity are changed, so that the vibration of floating plate is offset;c part is the highest point, and contains air bag, and b part bears damping and sound-insulating effect together, and bearing capacity is increased when greater load.

[0006] Further, the pressure-bearing damping structure is processed by electric heating cutting machine, and the resistance wire is heated to 200-300 DEG C, and then moves along the mark line at uniform speed, to ensure that the incision is smooth without debris, and to avoid edge charring caused by overheating.During transportation, the pressure-bearing damping structure can fit each other, reduce friction loss, and improve transportation efficiency.The flexible heat-reflective film is covered on the upper surface of the modified GPS flexible heat-insulating and sound-insulating mat, to play a heat-reflecting role, reduce heat transfer downward from floor heating, reflect part of heat source back to indoor, and reduce energy consumption.The flexible heat-reflective film is selected from flexible materials with good corrosion resistance, aging resistance, puncture resistance and high temperature resistance.

[0007] Particularly, the coating process sprays the coating on the flexible heat-reflective film after atomizing the coating by hot melt adhesive, realizes complex shape or local coating by high-pressure spraying, and the material utilization rate is high.Subsequently, the flexible heat-reflective film is transferred to the surface of the sound-insulating and heat-insulating mat by roller, and uniform and high-flexibility adhesive layer is formed by normal temperature curing.

[0008] Further, by different height design of a, b and c three parts, the sound-insulating mat can show excellent pressure-bearing damping performance under static load and dynamic load, while effectively reducing resonance frequency and reducing floor impact sound transmission.The combination of the flexible heat-reflective film and the pressure-bearing damping structure not only improves the installation stability and paving flatness of the sound-insulating mat, but also significantly enhances the heat-reflecting efficiency of the floor heating system, in line with the enterprise concept of sustainable development.

[0009] The application has the following beneficial effects: the pressure-bearing and vibration-reducing structure can automatically adapt to the ups and downs of the ground through the height difference design of the three parts a, b and c, ensures excellent overall flatness after paving, and solves the problem of poor ground flatness in the state of delivery of the raw house. The pressure-bearing and vibration-reducing structure exhibits different mechanical properties under static load and dynamic load, can effectively reduce the transmission of floor impact sound, and can provide additional bearing capacity under greater load, realizing the maximum compatibility of sound insulation and pressure-bearing performance.

[0010] Further, the flexible heat-reflecting film reduces the risk of being pierced by backfill fine stone concrete in the construction of floor heating, and the heat-reflecting function provided effectively reduces the downward heat transfer of floor heating, reflects part of the heat source back to the indoor, significantly reduces energy consumption, and cooperates with the sound insulation and heat preservation function of the sound insulation pad to greatly improve the energy-saving level. The integrated design of the modified GPS flexible heat-reflecting film and the sound insulation pad simplifies the construction process of the sound insulation pad and the heating and ventilation engineering, and improves the physical and chemical stability of the material and prolongs the service life.

[0011] In particular, the design of the pressure-bearing and vibration-reducing structure divides the functions of different height regions, so that the sound insulation pad has dynamic response capability in actual application. Specifically, the lowest point of part a bears the main static load, ensuring that the sound insulation pad can form stable contact with the ground during the initial installation stage. The middle height design of part b changes the ground contact area and dynamic stiffness under the action of dynamic load through intermittent contact with the ground, thereby effectively absorbing and dispersing impact energy and reducing vibration transmission. The highest point of part c contains an air bag, which utilizes the compressibility of air to provide elastic variables and increase the bearing capacity under greater load, while cooperating with part b to achieve the effect of vibration reduction and sound insulation.

[0012] Further, the coating process of the flexible heat-reflecting film uses hot melt adhesive coating and high-pressure spraying technology to ensure uniform distribution of the coating and high adhesion. The adhesive layer formed during the curing process at room temperature has high flexibility and durability, and can resist mechanical damage and environmental erosion during subsequent construction. The material selection of the flexible heat-reflecting film is based on its corrosion resistance, aging resistance, puncture resistance and high temperature resistance, ensuring that it will not be damaged by the pressure of backfill fine stone concrete during wet floor heating construction, while maintaining stable heat-reflecting efficiency.

[0013] Particularly, the overall structure design of the modified GPS flexible thermal insulation and sound insulation pad realizes the integration of multiple functions of sound insulation, thermal insulation and heat reflection through the functional division of the upper and lower surfaces. The planar design of the upper surface facilitates the adhesion of the cloth, thereby reducing the transmission of floor impact sound; the pressure-bearing and vibration-reducing structure of the lower surface provides excellent sound insulation and pressure-bearing performance through a dynamic response mechanism. The combination of the flexible heat reflection film and the pressure-bearing and vibration-reducing structure not only improves the installation stability of the sound insulation pad, but also significantly enhances the heat reflection efficiency of the floor heating system, in line with the development trend of building energy saving and sound insulation technology.

[0014] Further, the technical solution has significant technical advantages in actual application. First, the dynamic response mechanism of the pressure-bearing and vibration-reducing structure enables the sound insulation pad to automatically adjust the mechanical properties according to load changes, solving the problem of incompatibility of sound insulation and pressure-bearing in the prior art. Second, the introduction of the flexible heat reflection film not only improves the heat reflection efficiency of the floor heating system, but also protects the physical and chemical properties of the sound insulation pad through its high flexibility and durability. Finally, the integrated design simplifies the construction process, improves the transportation and installation efficiency of materials, and provides a new solution for the application of building energy saving and sound insulation technology.

[0015] In summary, the present application solves a number of technical problems in the prior art through innovative pressure-bearing and vibration-reducing structure and flexible heat reflection film design, and has significant technical advantages and application value.

DETAILED DESCRIPTION

[0019] The present application relates to a nano-modified GPS flexible thermal insulation and sound insulation pad, and its technical solution realizes automatic adaptation of ground flatness, compatibility of sound insulation and pressure-bearing, and efficient heat reflection of the floor heating system through optimized structure design and process flow in actual construction and application. The following will combine the drawings to further illustrate the technical solution of the present application. Figure 1 The specific embodiments of the present application will be described in detail.

[0020] Figure 1The overall structure of the present application is shown in the schematic diagram, wherein the modified GPS flexible thermal insulation and sound insulation mat is composed of an upper surface 2, a pressure bearing and vibration reduction structure 3 and a flexible thermal reflective film 1. The pressure bearing and vibration reduction structure 3 contains three parts: a is the lowest point, b is the middle height part, and c is the highest point and contains an air bag. These parts work together to achieve the dynamic response characteristics of the sound insulation mat. The flexible thermal reflective film 1 is covered on the upper surface 2 of the sound insulation mat, which plays a role in reducing the downward heat transfer of the floor heating.

[0021] In the manufacturing process, first, the GPS plate is toughened. The GPS plate is placed on the compressor or rolling machine for extrusion, so that the internal structure is more compact and the toughness is enhanced. The GPS plate after toughening has good pressure resistance, which is convenient for subsequent processing. Next, the plastic cutting of the toughened GPS plate is carried out using an electric heating cutting machine. The resistance wire of the electric heating cutting machine is heated to 200-300°C, and then moved along the marked line at a uniform speed, ensuring that the cut is smooth and free of debris. This cutting method avoids the problem of edge charring caused by overheating, while ensuring the accurate formation of the pressure bearing and vibration reduction structure 3. The design of the pressure bearing and vibration reduction structure 3 is one of the core innovative points of the present application, which realizes excellent performance under static load and dynamic load through the functional division of different height areas.

[0022] The a part of the pressure bearing and vibration reduction structure 3 is located at the lowest point and directly contacts the ground, bearing the main static load. During installation, due to the unevenness of the ground in the state of the delivery of the commodity house, the a part can automatically adapt to the unevenness of the ground, ensuring that the whole sound insulation mat forms stable contact with the ground. The b part is located at the middle height, which is instantaneously locally sunken and stable under the self-weight of the floating plate such as the fine stone concrete protective layer and the finish layer. This feature enables the sound insulation mat to quickly adapt to the ground conditions and achieve the preset mechanical equilibrium state during the initial installation stage. When subjected to dynamic load, such as human running, jumping, walking or moving tables and chairs, the b part continuously or intermittently contacts the ground with varying load, changing the ground contact area, dynamic stiffness and bearing capacity, thereby absorbing and dispersing impact energy and reducing vibration transmission. The c part is located at the highest point and contains an air bag, which utilizes the compressibility of air to provide elastic variables. Under greater load, the c part increases the bearing capacity and cooperates with the b part to achieve the effect of vibration reduction and sound insulation.

[0023] The covering process of the flexible thermal reflective film 1 is another important innovative point of the present application. A flexible material with good corrosion resistance, aging resistance, puncture resistance and high temperature resistance is selected as the basic material of the thermal reflective film. The coating process uses hot melt adhesive to atomize and spray the coating onto the flexible thermal reflective film 1, and realizes complex shape or local coating through high-pressure spraying, with high material utilization rate. Then the flexible thermal reflective film 1 is transferred to the upper surface 2 of the sound insulation and thermal insulation mat by roller, and forms a uniform and high-flexibility adhesive layer after curing at room temperature. This process ensures that the coating is evenly distributed and has high adhesion, which can resist mechanical damage and environmental erosion in subsequent construction.

[0024] S4In actual construction scenarios, the combination of the flexible heat-reflective film 1 and the pressure-bearing and vibration-reducing structure 3 significantly improves the overall performance of the sound insulation mat. The flexible heat-reflective film 1 reduces the risk of being punctured by the fine stone concrete backfill in the floor heating construction, and the heat reflection function effectively reduces the heat transfer downward, reflecting part of the heat source back to the indoor, significantly reducing energy consumption. Combined with the sound insulation and heat preservation function of the sound insulation mat, the energy saving level is greatly improved. In addition, the high flexibility and durability of the flexible heat-reflective film 1 protect the physical and chemical properties of the sound insulation mat, prolonging the service life.

[0025] S5The upper surface 2 of the modified GPS flexible sound insulation and heat preservation mat is designed as a plane, which is convenient for sticking reinforcing cloth to reduce the transmission of floor impact sound. The reinforcing cloth is made of non-woven fabric or fiberglass mesh, which is pasted on the upper surface 2 of the sound insulation mat by hot melt adhesive. This design not only improves the strength of the sound insulation mat, but also further enhances the sound insulation effect. The pressure-bearing and vibration-reducing structure 3 on the lower surface is divided into different height areas, which makes the sound insulation mat have dynamic response ability in actual application. The lowest point of part a bears the main static load, ensuring that the sound insulation mat can form stable contact with the ground during the initial installation stage. The middle height design of part b changes the contact area and dynamic stiffness by intermittent contact with the ground under dynamic load, thereby absorbing and dispersing impact energy and reducing vibration transmission. The highest point of part c contains an air bag, which uses the compressibility of air to provide elastic variables, increasing the bearing capacity under larger loads, and at the same time, cooperates with part b to achieve the effect of vibration reduction and sound insulation.

[0026] S6During transportation, the pressure-bearing and vibration-reducing structures 3 can fit together, reducing friction loss and improving transportation efficiency. This design not only optimizes the logistics link, but also reduces transportation costs. In addition, the height difference design of the pressure-bearing and vibration-reducing structure 3 makes the sound insulation mat exhibit excellent flatness effect after paving, solving the problem that sound insulation and pressure bearing are difficult to be compatible in the prior art. The introduction of the flexible heat-reflective film 1 not only improves the heat reflection efficiency of the floor heating system, but also protects the physical and chemical properties of the sound insulation mat through its high flexibility and durability.

[0027] S7The technical scheme of the present application has significant technical advantages in practical application. The dynamic response mechanism of the pressure-bearing and vibration-reducing structure 3 enables the sound insulation mat to automatically adjust its mechanical properties according to load changes, solving the problem that sound insulation and pressure bearing are difficult to be compatible in the prior art.

[0028] In conclusion, the present application solves a plurality of technical problems existing in the prior art by virtue of the innovative pressure-bearing damping structure 3 and the flexible heat-reflecting film 1 design, and has significant technical advantages and application value.

[0029] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
