Description

Technical Field

[0001] The utility model relates to the field of paving, in particular to a thermoplastic elastomer composite paving coil, a paving site with good elastic recovery and a site with good elastic recovery. Background Art

[0002] Thermoplastic elastomers are called the third generation of rubber. They are a type of material that combines the elasticity of rubber with the melt fluidity and reusability of thermoplastics. Due to their excellent physical and mechanical properties, electrical insulation properties, and processing performance, they are widely used in many fields such as automobiles, electronics, wires and cables, medical equipment, and construction packaging.

[0003] At present, thermoplastic elastomers are gradually being applied to the paving field, but most of the existing thermoplastic elastomers are applied through the foaming process, but the foaming process cannot achieve effective water permeability and has a small application range. The paving materials prepared by other processes are not only costly, but also have poor impact absorption and elastic recovery capabilities, and are not suitable for widespread application.

[0004] Therefore, it is necessary to invent a thermoplastic elastomer paving material which has low cost, good impact absorption and elastic recovery capabilities, and good water permeability. Utility Model Content

[0005] The first purpose of the utility model is to provide a thermoplastic elastomer composite paving coil material, which is used to solve the problems that the existing thermoplastic elastomer paving materials are high in cost, have poor impact absorption and elastic recovery capabilities, and are not suitable for wide application.

[0006] The second purpose of the utility model is to provide a paved area with good elastic recovery, which is formed by splicing the above-mentioned thermoplastic elastomer composite paving coil.

[0007] The third object of the utility model is to provide a venue with good elastic recovery.

[0008] In order to achieve the above-mentioned first purpose, the utility model provides a thermoplastic elastomer composite paving coil comprising an elastomer wear-resistant surface layer, a wire loop buffer layer and a synthetic elastomer bonding layer, wherein the elastomer wear-resistant surface layer, the wire loop buffer layer and the synthetic elastomer bonding layer are arranged in sequence from top to bottom; wherein the wire loop buffer layer is a three-dimensional wire loop structure formed by a plurality of irregularly arranged thermoplastic elastomer extruded wires interlaced and wound with each other in a loosely spaced manner, and preferably, the thermoplastic elastomer extruded wire can be formed by extruding waste thermoplastic elastomer by breaking particles.

[0009] It can be seen from the above scheme that the buffer layer of the three-dimensional structure of the thermoplastic elastomer wire loop has a gap and an interconnected network structure, so that the paving coil can quickly return to its original shape after being deformed by external force. At the same time, the gaps between the wire loops can absorb and disperse the energy when impacted, so that the paving coil has good impact absorption performance and reduces the impact force on objects or human bodies. Moreover, the gaps between the wire loops can meet the needs of water-permeable scenes. Thermoplastic elastomer extruded wires are used to form wire loops, and the performance of the paving material is further improved by using the performance of the thermoplastic elastomer itself. At the same time, the preparation process is simple and the cost is low. An elastomer wear-resistant surface layer is set on the buffer layer of the thermoplastic elastomer wire loop, which protects the buffer layer of the wire loop, reduces the influence of the atmosphere, ozone, and ultraviolet rays on the thermoplastic elastomer, and ensures the service life of the paving material. Thermoplastic elastomer extruded wire can be formed by extruding waste thermoplastic elastomer through particle breaking, and solid waste can be recycled, which is more environmentally friendly, further reduces the cost, and provides a new direction for the recycling of thermoplastic elastomers. The provision of the synthetic elastomer bonding layer achieves bonding performance between the coiled material and the base surface, thereby ensuring the use of the prefabricated coiled material.

[0010] A further solution is that the elastomeric wear-resistant surface layer is formed by arranging a plurality of elastic microbodies. Preferably, the elastic microbodies are formed by means of elastic coating or spraying. The elastomeric wear-resistant surface layer is provided with water flow holes, which are formed by the gaps between two adjacent elastic microbodies.

[0011] It can be seen from the above scheme that water flow holes are provided on the elastic wear-resistant surface layer to further improve the water permeability of the paving coil.

[0012] A further solution is that the elastomeric wear-resistant surface layer is formed by a plurality of closely arranged elastic micro-bodies. Preferably, the elastic micro-bodies are formed by means of elastic coating or spraying, and two adjacent elastic micro-bodies are in contact with each other.

[0013] It can be seen from the above scheme that the elastic micro-bodies can be arranged closely, and there is no gap between two adjacent elastic micro-bodies for water to pass through. It can be used to prepare paving rolls that meet the requirements of impermeability, making the application range of paving rolls wider.

[0014] In a further embodiment, the elastomeric wear surface layer is made of semi-polyurea.

[0015] As can be seen from the above scheme, the use of semi-polyurea to prepare the elastomeric wear-resistant surface layer can achieve instant curing, simple construction methods, and ensure the efficiency of paving coil preparation. At the same time, semi-polyurea has excellent physical and chemical properties, which makes semi-polyurea materials perform well in the surface layer of paving materials, can resist the erosion of various environmental factors, and maintain long-term stability and aesthetics. Semi-polyurea has excellent weather resistance, durability and corrosion resistance, and can withstand the erosion of most chemicals, ozone, radiation, water and other adverse environmental conditions. It meets the physical properties of paving coils such as water permeability, wear resistance, anti-slip, impact absorption and strength, and has excellent wear resistance, thereby achieving quality assurance of paving coils within the service life, having a good protective effect on the wire loop buffer layer and being suitable for paving requirements in various environments. Semi-polyurea materials are odorless, non-toxic, and will not cause harm to the human body. No harmful substances will be generated during the construction process and use process, which meets environmental protection requirements.

[0016] In a further embodiment, the thermoplastic elastomer extruded filament is made of one of styrene-based thermoplastic elastomer, thermoplastic vulcanized rubber or thermoplastic polyurethane elastomer.

[0017] It can be seen from the above scheme that the above thermoplastic elastomer material is easy to process, has good elasticity, and is environmentally friendly.

[0018] A further solution is that the synthetic elastomer bonding layer is butyl rubber self-adhesive.

[0019] As can be seen from the above scheme, butyl rubber self-adhesive has excellent bonding strength, excellent chemical resistance, weather resistance and corrosion resistance. It can maintain stable performance under various temperature conditions, and form a good bond with the surface of the adherend. It has a long service life and can resist the performance degradation caused by long-term use and aging. At the same time, butyl rubber self-adhesive does not contain solvents, so it will not release toxic gases or cause pollution to the environment.

[0020] A further solution is that the thermoplastic elastomer composite paving roll also includes an isolation paper layer, and the isolation paper layer is located below the synthetic elastomer bonding layer.

[0021] It can be seen from the above scheme that the provision of the isolation paper layer makes the transportation process of the paving roll material more convenient.

[0022] In a further embodiment, the release paper layer is a polyester film coated with silicon or a polyethylene film coated with silicon.

[0023] As can be seen from the above scheme, the surface coated with silicon can give the polyester film or polyethylene film excellent slip and anti-stick properties. It can be easily peeled off from the synthetic elastomer bonding layer, reducing adhesion and tearing, and improving paving efficiency. At the same time, the polyester film or polyethylene film coated with silicon has good tolerance to most chemicals, solvents and weather conditions. It is environmentally friendly and non-toxic.

[0024] In order to achieve the above-mentioned second purpose, the utility model provides a paved area with good elastic recovery, which is formed by splicing a thermoplastic elastomer composite paving coil as described in any of the above schemes.

[0025] As can be seen from the above scheme, the thermoplastic elastomer composite paving coil can be prefabricated into paving coils according to the requirements of different sites, which is easy to operate and has a wide range of applications. The resulting paving site with good elastic recovery has good elastic recovery ability and impact absorption ability.

[0026] In order to achieve the above-mentioned third purpose, the utility model provides a venue with good elastic recovery, which includes an elastomeric wear-resistant surface layer, a wire loop buffer layer and a synthetic elastomer bonding layer, the synthetic elastomer bonding layer is arranged above a base surface, the wire loop buffer layer is arranged above the synthetic elastomer bonding layer, and the elastomer wear-resistant surface layer is arranged above the wire loop buffer layer; wherein the wire loop buffer layer is a three-dimensional wire loop structure formed by a plurality of irregularly arranged thermoplastic elastomer extruded wires interlaced and wound with each other in a loosely spaced manner.

[0027] It can be seen from the above scheme that the site with good elastic recovery is formed by on-site construction. The construction method is simple, efficient and low-cost. Construction with different thicknesses and different performance requirements can be carried out according to different site requirements. It has a wide range of applications, and the site after construction has good elastic recovery and impact absorption capabilities. BRIEF DESCRIPTION OF THE DRAWINGS

According to the requirements of different paving scenes, the wire loop buffer layer 12 can choose whether to perform a pressing process to make the surface flat during the preparation process, so as to prepare a coiled material suitable for different paving scenes.

The thermoplastic vulcanized rubber extrusion wire is formed by extruding the waste thermoplastic vulcanized rubber through particle breaking, and the solid waste is recycled, which is more environmentally friendly, further reduces the cost, and provides a new direction for the recycling of thermoplastic elastomers. The synthetic elastomer bonding layer 13 can be arranged on the isolation paper layer 14 by an extrusion process, the thermoplastic vulcanized rubber extruded wires in the wire loop buffer layer 12 are interlaced and wound with each other in a loosely spaced manner to form above the synthetic elastomer bonding layer 13, and the elastomer wear-resistant surface layer 11 is sprayed on the surface of the wire loop buffer layer 12.

In addition, the paving coil of this embodiment is a prefabricated coil, which is convenient and quick to use, greatly saving the paving construction time and cost.

[0038] Since there are no gaps on the surface of the elastic wear-resistant surface layer 11 in this example through which water can pass, the performance requirements of a water-impermeable paved site can be met.
