Abstract
Description
Technical Field
[0001] This utility model relates to the field of building materials technology, and in particular to PVC composite panels with thermal insulation properties. Background Technology
[0002] With the improvement of people's living standards and the increasing demands for building comfort, building insulation has become a key focus in the construction industry. Whether residential or industrial, buildings require effective insulation measures to reduce heat transfer, lower energy consumption, improve indoor thermal stability, and provide a more comfortable living and working environment. For example, in cold regions, it is necessary to keep indoor temperatures warm in winter to reduce heat loss to the outside; in hot regions, it is necessary to prevent outdoor heat from entering the interior in summer to reduce air conditioning energy consumption.
[0003] Typical PVC composite panels consist of two side substrates, a central support layer, and a reinforcing layer. The side substrates form a physical barrier to resist external impacts, while providing a flat appearance and basic support surface for the entire panel, ensuring the integrity and durability of the panel during use. The central support layer, with its mesh-like porous structure design, distributes the main load of the panel by distributing the force. The reinforcing layer, with its metal mesh embedded in the structure, utilizes the high tensile strength and ductility of the material to generate reverse stress when the panel is subjected to external forces such as bending and stretching, thereby enhancing the panel's resistance to deformation and structural stability.
[0004] The PVC composite panels in some of the aforementioned technologies have severely insufficient thermal insulation performance. When applied, they cannot effectively block the exchange of heat between indoors and outdoors, leading to increased air conditioning energy consumption and significant energy waste. In cold chain packaging scenarios, they also struggle to maintain stable internal temperatures, affecting the preservation of goods. As society's demands for energy conservation, environmental protection, and comfortable living environments continue to rise, the shortcomings of existing PVC composite panels in terms of thermal insulation and sound insulation can no longer meet practical application needs. Therefore, a PVC composite panel with thermal insulation properties is proposed to address these issues. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 2 and Figure 5 This utility model provides an embodiment of a PVC composite board with thermal insulation effect, comprising an outer base layer 1. The outer base layer 1, as the outermost structure of the board, provides basic mechanical strength, resists external impacts, friction, and other physical effects, and also provides weather resistance and corrosion resistance. A main adhesive layer 2 is fixedly connected to the bottom of the outer base layer 1, connecting the outer base layer 1 and the thermal insulation layer 3, ensuring a tight bond between the two layers and further enhancing the thermal insulation performance. The thermal insulation layer 3 is fixedly connected to the bottom of the main adhesive layer 2, serving as the core thermal insulation structure of the board, significantly reducing the heat conduction rate and achieving a thermal insulation effect. A secondary adhesive layer 4 is fixedly connected to the bottom of the thermal insulation layer 3, connecting the thermal insulation layer 3 and the microporous structure layer 5, with a function similar to the main adhesive layer 2, and also serving as a microporous structure layer. The porous structure layer 5 provides a flat adhesion base. The bottom of the secondary adhesive layer 4 is fixedly connected to the microporous structure layer 5. The microporous structure layer 5 optimizes the thermal insulation performance through the gradient distribution of microporous grooves 15, and at the same time assists in sound insulation. It is a key structure for realizing multi-functional integration. The bottom of the microporous structure layer 5 is fixedly connected to the sound insulation layer 6. The sound insulation layer 6 absorbs and dissipates sound wave energy through the cross groove structure 16, thereby improving the sound insulation performance of the board. The bottom of the sound insulation layer 6 is fixedly connected to the reinforcing layer 7. The reinforcing layer 7 improves the overall mechanical strength and deformation resistance of the board and prevents cracking due to external forces or temperature changes. The bottom of the reinforcing layer 7 is fixedly connected to the inner base layer 8. The inner base layer 8 serves as the inner layer structure of the board and forms symmetrical support with the outer base layer 1, thereby enhancing the overall stability of the board and providing internal protection.
[0034] The microporous structure layer 5 has multiple micropore grooves 15 both horizontally and vertically inside. These micropore grooves 15, through a gradient distribution, optimize thermal insulation and sound insulation performance and are the core functional structure of the microporous structure layer 5. The distribution of the micropore grooves 15 adopts a gradient design, with larger micropore grooves 15 closer to the thermal insulation layer 3 and smaller pore diameters on the side farther from the thermal insulation layer 3. The larger pore diameter micropores closer to the thermal insulation layer 3 utilize more air chambers to form a thermal barrier, while the smaller pore diameter micropores farther from the thermal insulation layer 3 reduce gas convection. The reflection and absorption of sound waves by the micropore walls are adjusted according to the pore diameter. The sound insulation layer 6 has multiple cross grooves 16 both horizontally and vertically inside. These cross grooves 16, through their varying lengths and widths, achieve broadband absorption of sound waves of different frequencies. The distribution of the cross grooves 16 adopts a width-to-width design, with multiple cross grooves 16... The 6th layer is divided into a longer and a wider cross groove 16. The longer cross groove 16 resonates and absorbs low-frequency sound waves, while the wider cross groove 16 dissipates high-frequency sound waves through friction. The two grooves work together to extend the sound insulation band. The outer base layer 1 is made of rigid PVC, which increases the surface hardness and load-bearing capacity of the board. The inner base layer 8 is made of rigid PVC, which increases the surface hardness and load-bearing capacity of the board. The insulation layer 3 is made of polystyrene foam, which increases thermal resistance and effectively blocks heat flow. The main adhesive layer 2 is made of aerogel, which increases the connection strength between the outer base layer 1 and the insulation layer 3 and adds an extra thermal insulation barrier. The secondary adhesive layer 4 is made of aerogel. The reinforcing layer 7 is made of metal mesh. The microporous structure layer 5 is made of polyethylene foam, which reduces the overall thermal conductivity of the board and prevents it from collapsing during long-term use.
[0035] Reference Figures 2 to 4 The outer base layer 1 has multiple top grooves 9 on its exterior. These grooves are used to install fasteners or connect with other components and also serve as drainage channels. The outer base layer 1 has multiple top inner support grooves 10 horizontally inside. These grooves enhance the bending resistance of the outer base layer 1 and improve the surface rigidity of the board. The outer base layer 1 also has multiple serrated grooves 11 vertically inside. These grooves allow for the injection of a molding solution, increasing the plasticity and insulation effect of the outer base layer 1. The inner base layer 8 has multiple bottom grooves 12 on its exterior. These grooves are used for internal installation or connection and also serve as ventilation channels. The inner base layer 8 has multiple bottom inner support grooves 13 horizontally inside. These grooves function similarly to the top inner support grooves 10, enhancing the structural rigidity of the inner base layer 8. The inner base layer 8 also has multiple round toothed grooves 14 vertically inside. These grooves allow for the injection of a molding solution, increasing the plasticity and insulation effect of the inner base layer 8.
[0036] Working principle: The outer base layer 1 is fixedly connected to the insulation layer 3 through the main adhesive layer 2. The main adhesive layer 2 ensures that the two layers are tightly bonded. The insulation layer 3, as the core insulation structure, significantly reduces the heat conduction rate and achieves the heat insulation effect. The insulation layer 3 is connected to the microporous structure layer 5 through the secondary adhesive layer 4. The secondary adhesive layer 4 provides a flat adhesion base for the microporous structure layer 5. The microporous grooves 15 in the horizontal and vertical directions inside the microporous structure layer 5 are distributed in a gradient. The large-diameter micropores on the side close to the insulation layer 3 form a thermal barrier using air chambers, while the small-diameter micropores on the side away from the insulation layer 3 reduce gas convection, thereby optimizing the heat insulation performance. The microporous structure layer 5 is connected to the reinforcing layer 7 through the sound insulation layer 6. The reinforcing layer 7 improves the overall mechanical strength and deformation resistance of the board. The reinforcing layer 7 is fixedly connected to the inner base layer 8. The inner base layer 8 and the outer base layer 1 form symmetrical support, enhancing the overall stability of the board.
[0037] The sound insulation layer 6 has horizontal and vertical cross grooves 16 inside, which absorb sound waves of different frequencies through groove structures of different lengths and widths. The top groove 9 on the outside of the outer base layer 1 can be used to install fasteners or for drainage. The top inner support groove 10 inside enhances the bending resistance. The serrated groove 11 can be injected with plasticizing solution to increase plasticity and heat insulation effect. The bottom groove 12 on the outside of the inner base layer 8 can be used for internal installation or ventilation. The bottom inner support groove 13 inside enhances the structural rigidity. The round toothed groove 14 can be injected with plasticizing solution to increase plasticity and heat insulation effect.
