Description

Technical Field

[0001] This utility model relates to the technical field of wear-resistant rubber sheets, specifically to a wear-resistant thermoplastic rubber sheet. Background Technology

[0002] Rubber sheets are sheet-like products with a certain thickness and a large area, made of rubber as the main material (which may contain reinforcing materials such as fabric and thin metal sheets) through vulcanization. They are simply called rubber sheets. Rubber sheets have high hardness and general physical and mechanical properties. They are made by calendering or extruding compounded rubber, and then vulcanizing them with a flat vulcanizing machine or a drum vulcanizing machine. They are widely used in industrial and mining enterprises, transportation departments, and building floors, and are used as sealing rings, gaskets, door and window seals, and for laying workbenches and floors.

[0003] In existing technologies, the support is provided solely by the hardness of the rubber sheet, which makes the rubber sheet prone to significant deformation during long-term use. Furthermore, the outer rubber layer is difficult to bond with other materials, thus reducing its elasticity and wear resistance. Therefore, this device provides a wear-resistant thermoplastic rubber sheet. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a wear-resistant thermoplastic rubber sheet to solve the aforementioned technical problems.

[0005] The present invention adopts the following technical solution: a wear-resistant thermoplastic rubber sheet, comprising a rubber sheet, wherein a plurality of wear-resistant rubber strips are fixedly installed on the front side of the rubber sheet, and a wear-resistant coating is provided on the outer side of the rubber sheet and the wear-resistant rubber strips;

[0006] A reinforcing plate is slidably provided on the inner side of the rubber sheet, and a connecting block is fixedly installed on one side of the reinforcing plate;

[0007] A fastening plate is provided above the rubber sheet, and multiple fastening blocks are fixedly installed at the bottom of the fastening plate.

[0008] As a further improvement to the above solution, a sliding groove is provided on the top of the rubber sheet, and the reinforcing plate is fitted into the sliding groove.

[0009] As a further improvement to the above solution, the top of the rubber sheet is provided with multiple connecting grooves, the connecting block fits into the connecting grooves, and both the connecting block and the connecting groove are trapezoidal in shape.

[0010] As a further improvement to the above solution, the top of the connecting block and the rubber plate is provided with multiple conical grooves, the fastening block is conical in shape, and the fastening block fits into the conical grooves.

[0011] As a further improvement to the above solution, multiple rubber protrusions are provided above the rubber sheet and the wear-resistant rubber strip. The materials of the rubber sheet and the wear-resistant rubber strip include styrene-butadiene-styrene block copolymer, thermoplastic vulcanizate, and hydrogenated nitrile rubber.

[0012] As a further improvement to the above solution, the wear-resistant coating is made of polyurethane, epoxy resin and polytetrafluoroethylene, and the reinforcing plate is made of metal wire mesh, fiber-reinforced composite material and thermoplastic elastomer alloy.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0014] 1. Insert the reinforcing plate into the inner side of the rubber sheet. A sliding groove and a connecting groove are provided on the top of the rubber sheet. The reinforcing plate fits into the sliding groove, and the connecting block can be connected to the connecting groove, making the connection between the rubber sheet and the reinforcing plate more convenient and tight. Insert the conical fastening block into the inner side of the rubber sheet and the reinforcing plate from above. A slot is provided on the top of the rubber sheet and the connecting block. Since the outer diameter of the fastening block is larger than the inner diameter of the slot, the connection between the fastening block and the rubber sheet and the connecting block is tighter and less likely to separate.

[0015] Second, the reinforcing plate serves as a mechanical support framework, enhancing the overall structural strength and rigidity. It evenly transmits external pressure to the rubber matrix, preventing deformation or cracking caused by localized stress concentration; it absorbs impact energy through its own elastic deformation, reducing the damage of external impact forces to the underlying rubber. The wear-resistant coating, as the outermost protective barrier of the rubber sheet, bears the heavy responsibility of directly contacting the external environment, effectively resisting physical and chemical damage such as friction, impact, chemical corrosion, and ultraviolet radiation.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] This utility model embodiment provides a wear-resistant thermoplastic rubber sheet, including a rubber sheet 1, a plurality of wear-resistant rubber strips 2 fixedly installed on the front side of the rubber sheet 1, and a wear-resistant coating 3 provided on the outer side of the rubber sheet 1 and the wear-resistant rubber strips 2.

[0026] A reinforcing plate 4 is slidably provided on the inner side of the rubber sheet 1, and a connecting block 5 is fixedly installed on one side of the reinforcing plate 4;

[0027] A fastening plate 6 is provided above the rubber plate 1, and multiple fastening blocks 7 are fixedly installed at the bottom of the fastening plate 6.

[0028] Furthermore, the three-layer structure achieves complementary performance through interface compatibility design; the wear-resistant coating 3 resists surface damage, the reinforcing plate 4 provides structural support, and the rubber plate 1 buffers energy impact; the reinforcing plate 4 and the rubber plate 1 form a "rigid-flexible coupling" system through chemical grafting or physical winding, which ensures both strength and elasticity.

[0029] In a further preferred embodiment of the present invention, a sliding groove is provided on the top of the rubber plate 1, and the reinforcing plate 4 is fitted into the sliding groove.

[0030] Furthermore, the reinforcing plate 4 is inserted into the inner side of the rubber plate 1. A sliding groove and a connecting groove are provided on the top of the rubber plate 1. The reinforcing plate 4 fits into the sliding groove, and the connecting block 5 can be connected to the connecting groove, so that the rubber plate 1 is connected more conveniently and tightly.

[0031] In a further preferred embodiment of the present invention, the top of the rubber sheet 1 is provided with a plurality of connecting grooves, the connecting block 5 is fitted with the connecting grooves, and the shape of the connecting block 5 and the connecting grooves are both trapezoidal.

[0032] Furthermore, both the connecting groove and the connecting block 5 are trapezoidal, which allows the reinforcing plate 4 to be connected more tightly to the rubber plate 1, and makes the positioning connection more convenient and quick.

[0033] In a further preferred embodiment of the present invention, the top of the connecting block 5 and the rubber plate 1 are provided with a plurality of conical grooves, the fastening block 7 is conical in shape, and the fastening block 7 fits into the conical grooves.

[0034] Furthermore, the conical fastening block 7 is inserted from above into the inner side of the rubber plate 1 and the reinforcing plate 4. A slot is provided on the top of the rubber plate 1 and the connecting block 5. Since the outer diameter of the fastening block 7 is larger than the inner diameter of the slot, the connection between the fastening block 7 and the rubber plate 1 and the connecting block 5 can be relatively tight, and separation is not likely to occur.

[0035] In a further preferred embodiment of the present invention, a plurality of rubber protrusions are provided above the rubber plate 1 and the wear-resistant rubber strip 2. The materials of the rubber plate 1 and the wear-resistant rubber strip 2 include styrene-butadiene-styrene block copolymer, thermoplastic vulcanizate and hydrogenated nitrile rubber.

[0036] Furthermore, the rubber sheet, as the main material of the rubber sheet, provides basic elasticity, cushioning performance, and environmental adaptability.

[0037] Its high elasticity absorbs the impact of equipment vibration or human movement, reducing fatigue; its dense rubber structure prevents liquid penetration, making it suitable for humid or corrosive environments; it maintains good elasticity in a temperature range of -40℃ to 120℃, meeting the needs of wide-temperature applications.

[0038] The materials used for rubber sheets include styrene-butadiene-styrene block copolymers, thermoplastic vulcanizates, and hydrogenated nitrile rubber. Styrene-butadiene-styrene block copolymers have excellent resilience and low-temperature resistance, and are widely used in sports mats and shock-absorbing pads. Thermoplastic vulcanizates are rubber-plastic blends formed through dynamic vulcanization processes, combining the elasticity of rubber with the processability of plastics. Hydrogenated nitrile rubber has outstanding oil resistance and high-temperature resistance, and is suitable for industrial equipment seals and oil pipe linings.

[0039] In a further preferred embodiment of this utility model, the wear-resistant coating 3 is made of polyurethane, epoxy resin and polytetrafluoroethylene, and the reinforcing plate 4 is made of metal wire mesh, fiber-reinforced composite material and thermoplastic elastomer alloy.

[0040] Furthermore, the wear-resistant coating, as the outermost protective barrier of the rubber sheet, bears the heavy responsibility of directly contacting the external environment and effectively resists physical and chemical damage such as friction, impact, chemical corrosion and ultraviolet radiation.

[0041] By reducing surface wear, the rubber sheet maintains its integrity under high-frequency use or harsh conditions, extending its service life. The smooth, dense surface structure reduces the adhesion of dust, oil, and other contaminants, facilitating cleaning and maintenance. A special anti-slip texture design increases surface friction, making it suitable for scenarios with high anti-slip requirements. The wear-resistant coating materials include polyurethane, epoxy resin, and polytetrafluoroethylene (PTFE). Polyurethane offers excellent wear resistance and tear strength, along with good elastic recovery. Epoxy resin, modified with nanoparticles, forms a high-strength wear-resistant layer with outstanding chemical corrosion resistance, resisting acid and alkali corrosion. PTFE has an extremely low surface friction coefficient, suitable for special scenarios requiring reduced friction resistance. The reinforcing plate acts as a mechanical support framework, strengthening the overall structural strength and rigidity. It evenly transmits external pressure to the rubber matrix, preventing deformation or cracking caused by localized stress concentration. It absorbs impact energy through its own elastic deformation, reducing damage to the underlying rubber from external impacts. It inhibits creep caused by temperature changes or long-term loads, maintaining the shape stability of the rubber sheet.

[0042] The materials used in the reinforcement plate include metal wire mesh, fiber-reinforced composite materials, and thermoplastic elastomer alloys. Metal wire mesh: woven from stainless steel or low-carbon steel wire, forming a mechanically interlocking structure with the rubber matrix, significantly improving tensile strength. Fiber-reinforced composite materials: blended with rubber using glass fiber, carbon fiber, or aramid fiber, combining high strength and lightweight properties. Thermoplastic elastomer alloys: combining rigid resin with rubber through dynamic vulcanization technology, improving modulus while maintaining elasticity.

[0043] The specific operation is as follows: the reinforcing plate 4 is inserted into the inner side of the rubber plate 1. A sliding groove and a connecting groove are provided on the top of the rubber plate 1. The reinforcing plate 4 fits into the sliding groove, and the connecting block 5 can be connected to the connecting groove, so that the connection between the rubber plate 1 and the reinforcing plate 4 is relatively convenient and tight. The conical fastening block 7 is inserted into the inner side of the rubber plate 1 and the reinforcing plate 4 from above. A slot is provided on the top of the rubber plate 1 and the connecting block 5. Since the outer diameter of the fastening block 7 is larger than the inner diameter of the slot, the connection between the fastening block 7 and the rubber plate 1 and the connecting block 5 is relatively tight and it is not easy for them to separate. The reinforcing plate 4 serves as a mechanical support frame to strengthen the overall structural strength and rigidity. The external pressure is evenly transmitted to the rubber matrix, avoiding deformation or cracking caused by localized stress concentration; the wear-resistant coating 3 absorbs impact energy through its own elastic deformation, reducing the damage of external impact forces to the underlying rubber. As the outermost protective barrier of the rubber sheet, it bears the heavy responsibility of directly contacting the external environment, effectively resisting physical and chemical damage such as friction, impact, chemical corrosion, and ultraviolet radiation; by reducing surface wear, the rubber sheet can still maintain its integrity under high-frequency use or harsh working conditions, thus extending its service life; the smooth and dense surface structure reduces the adhesion of contaminants such as dust and oil stains, making it easy to clean and maintain; the special anti-slip texture design increases the friction of the contact surface, making it suitable for scenarios with high anti-slip requirements.

[0044] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
