Description

Technical Field

[0001] This invention relates to the field of thermoplastic elastomer processing technology, and more specifically, to a non-slip embossed TPE tension sheet structure and preparation process, applicable to the field of fitness equipment, and capable of producing TPE tension sheet products that combine high elasticity, non-slip properties and excellent surface texture. Background Technology

[0002] With the improvement of residents' living standards and the enhancement of health awareness, fitness activities have gradually become more popular, and fitness equipment is showing a trend towards miniaturization and portability. Resistance bands have become one of the most popular small fitness equipment due to their flexible use (both indoor and outdoor), portability, and ability to effectively improve physical activity and shape the body.

[0003] Currently, the mainstream materials for resistance bands on the market are mainly natural latex or synthetic latex. However, these latex resistance bands have obvious drawbacks: high production costs, complex molding and processing technology, easy pollution to the environment during production, and difficulty in recycling after product disposal, which does not meet the needs of environmental protection development.

[0004] Thermoplastic elastomers (TPEs), as a new type of environmentally friendly material, combine the high elasticity, high strength, and high resilience of rubber with the plasticity of plastics. They have advantages such as being environmentally friendly and non-toxic, having a wide range of hardness, excellent colorability, soft touch, good weather resistance and fatigue resistance, and not requiring vulcanization for processing. They have broad application prospects in sports products, home appliances, automotive materials and other fields.

[0005] In existing technologies, TPE tension sheets are typically prepared from polypropylene (PP), hydrogenated styrene-butadiene-styrene block copolymer (SEBS, oil-extended), and fillers. Among these, SEBS exhibits excellent weather resistance, low-temperature resistance, environmental friendliness, and recyclability, making it an ideal elastomer for preparing tension sheets. PP can reduce the melt viscosity of SEBS to improve processability and enhance the mechanical properties of the system. Fillers can further optimize the mechanical and thermodynamic properties of the material.

[0006] However, current TPE resistance band products still have shortcomings: on the one hand, most TPE resistance bands on the market have a smooth surface, requiring the application of talcum powder or baby powder to alleviate the stickiness, but the anti-slip properties are poor during use, and the powder falls off after repeated use, resulting in a deterioration in the feel; on the other hand, although some TPE resistance bands have achieved a dry and matte surface effect through formula optimization, such as the matte dry and high-elastic formula disclosed in patent CN114773767B, the anti-slip problem at the structural level has not been solved, and they cannot meet users' needs for high anti-slip performance.

[0007] Therefore, there is an urgent need to develop a new TPE tensile sheet structure and manufacturing process. While retaining the advantages of TPE material such as high elasticity and environmental friendliness, the structure should be improved to enhance the product's anti-slip properties and surface texture, while simplifying the production process and reducing costs. Summary of the Invention

[0008] To address the problems of poor anti-slip properties and insufficient surface texture in existing TPE tensile sheets, as well as the complexity of traditional production processes requiring powder coating, this invention provides an anti-slip embossed TPE tensile sheet structure and manufacturing process, achieving the following objectives: improving the surface anti-slip properties and dryness of TPE tensile sheets, enhancing the user experience; optimizing the product surface texture and enriching its appearance; simplifying the production process, eliminating the need for powder coating, improving production efficiency, reducing production costs, and facilitating automated production.

[0009] The technical solution of this invention is implemented as follows:

[0010] One aspect of the present invention:

[0011] An anti-slip embossed TPE tensile sheet structure includes a base layer and an embossed layer, wherein;

[0012] The base layer uses a matte, dry, high-elasticity TPE material disclosed in patent CN114773767B. The raw materials, by weight, include: 100 parts SEBS, 10-30 parts styrene elastomer, 80-120 parts paraffin oil, 5-10 parts talc, 0.1-0.5 parts antioxidant, and 0.1-0.5 parts light stabilizer. The base layer possesses high elasticity, with a tensile permanent deformation ≤6.57%, a dry, matte surface, and a gloss level of 15-25%, providing a stable substrate for the embossed layer.

[0013] The embossed layer is formed by pressing specific textures onto the base surface using an embossing roller. Texture types include, but are not limited to, grid patterns, leather textures, wood grain, dot patterns, brushed textures, matte textures, and carbon fiber textures. The texture depth of the embossed layer is 0.1-0.3mm, and the texture spacing is 0.5-2mm. This increases surface friction to improve slip resistance while enhancing both visual and tactile texture.

[0014] Another aspect of the present invention:

[0015] A process for preparing anti-slip embossed TPE tensile sheets includes the following steps:

[0016] Step S1, Preparation of base material: Weigh SEBS, styrene elastomer, paraffin oil, talc, antioxidant, and light stabilizer according to the formula; mix SEBS and paraffin oil, and stir at room temperature for 30-60 minutes to ensure that SEBS fully absorbs oil and there is no obvious oil separation phenomenon; add the oil-absorbed SEBS mixture, styrene elastomer, talc, antioxidant, and light stabilizer into a twin-screw extruder, control the extrusion temperature at 170-220℃, wherein the screw zone temperatures are: Zone 1 170-180℃, Zone 2 180-190℃, Zone 3 190-200℃, Zone 4 200-210℃, and the die head 210-220℃, and the screw speed is 300-500 r / min, and extrude and granulate to obtain base TPE granules.

[0017] Step S2, base layer extrusion molding: Add base layer TPE granules to a single screw extruder, control the extrusion temperature at 150-190℃, wherein the screw zone temperatures are: Zone 1 150-160℃, Zone 2 160-170℃, Zone 3 170-190℃, and die head 180-190℃, and the screw speed is 100-150 r / min; the material is extruded through the molding die into a continuous TPE sheet with a thickness of 0.1-1.5mm and a width of 200-400mm. During the extrusion process, melt rheology control technology is used to controllably cause fine and uniform melt fracture on the surface of the sheet, initially forming a dry matte surface.

[0018] The high-temperature TPE base sheet extruded from a single screw is introduced into an embossing roller machine (the cooling circulating water of the embossing roller is controlled at 10-50℃), where the texture is pressed and initially cooled and shaped under conditions of 0.1MPa-1MPa. Then, it is cooled to 10-30℃ by a cooling roller group or water tank to fix the texture.

[0019] The cooled sheet is conveyed to the cutter by a traction device to obtain anti-slip embossed TPE tensile sheet.

[0020] Step S3, embossing layer preparation: The extruded, uncooled TPE base sheet is introduced into the embossing roller machine. The surface of the embossing roller machine is engraved with a preset texture. The temperature of the embossing roller is controlled at 10-50℃ to ensure that the texture is pressed on the base surface and initially cooled and shaped. The pressure of the roller is 0.1MPa-1MPa, and the linear speed of the roller is matched with the extrusion speed to form an embossed layer on the base surface. The embossed sheet immediately enters the cooling roller group and is cooled at a temperature of 20-40℃ or in a water bath to set the embossed texture and prevent shrinkage and deformation.

[0021] Step S4: The cooled embossed TPE sheet is conveyed to the cutter via a traction device and cut according to the preset length and width; the finished products are packaged and stored after passing inspection.

[0022] The beneficial effects of this invention are:

[0023] 1. This invention significantly improves anti-slip properties: The textured structure of the embossed layer increases the surface friction of the tension sheet, making it less prone to slipping during use. Even with sweaty hands, it can maintain a stable grip, solving the problem of poor anti-slip properties of traditional smooth TPE tension sheets;

[0024] 2. This invention achieves surface texture and feel optimization: The embossed layer enriches the product's appearance, such as grid patterns and leather textures, creating a strong sense of visual depth; at the same time, combined with the dry and matte characteristics of the base layer, it avoids a sticky feeling, and the feel remains excellent even after multiple uses.

[0025] 3. This invention achieves improved production efficiency and reduced costs: The process eliminates the need for powdering, simplifying the production process, reducing powder storage, coating, and recycling, thus reducing raw material consumption and equipment investment. Furthermore, it can achieve continuous production through automated production lines, significantly improving production efficiency.

[0026] 4. This invention preserves material properties: The base layer uses a mature high-elasticity TPE formula, and the embossing process does not damage the structure of the base material. The product still maintains high elasticity, achieving a tensile permanent deformation of ≤6.57%, weather resistance, environmental friendliness, and recyclability, which is in line with the concept of green production.

[0057] To verify the advantages of the anti-slip embossed TPE tensile sheet of the present invention in terms of anti-slip properties, surface texture, and mechanical properties, using the above technical solution, Examples 1, 2, and 3 were selected as example groups, and two mainstream products were selected as control groups. Key performance indicators were compared through standardized experiments to clarify the advanced nature of the technical solution of the present invention. Control group 1 consisted of ordinary smooth TPE tensile sheet, using a traditional SEBS, PP, and paraffin oil formula, with no embossing on the surface, and coated with talcum powder at the factory; this is a mainstream product on the market. Control group 2 consisted of unembossed matte TPE tensile sheet, with a base layer of CN114773767B formula, no embossing on the surface, and matte finish achieved solely through melt fracture.

[0058] The experiments were conducted separately, as follows:

[0059] Among them, the anti-slip test was carried out to simulate the grip of the human hand. The anti-slip performance was evaluated by measuring the static friction coefficient between the tension plate and the simulated skin (silicone material, Shore A hardness 50±5). The higher the friction coefficient, the better the anti-slip performance.

[0060] Testing equipment: Universal testing machine (equipped with friction coefficient testing accessories).

[0061] Test conditions: Load: 50N (simulating the normal grip force of an adult);

[0062] Test environment: temperature 23±2℃, relative humidity 50±5%; divided into dry state (simulating dry hands) and wet state (simulating sweating hands, 0.5mL of deionized water was evenly sprayed on the simulated skin surface).

[0063] Testing standard: Refer to the friction coefficient test method in GB / T4100-2015 "Ceramic Tiles".

[0064] Among them, surface texture and feel tests were conducted, as follows:

[0065] Gloss test: Equipment: Gloss meter (test angle 60°); Standard: ASTM D2457-2013 "Standard Test Method for Gloss of Plastics and Films"; Procedure: Select 5 evenly distributed test points for each sample and take the average value. The lower the gloss, the better the matte effect.

[0066] Feel Rating Test: Rating Team: 10 professional testers (5 men and 5 women, aged 25-40, all with more than 3 years of experience in testing fitness equipment); Rating Dimensions: Stickiness (1-5 points, 1 point is extremely sticky, 5 points is not sticky), Touch Fineness (1-5 points, 1 point is rough, 5 points is fine), Grip Stability (1-5 points, 1 point is easy to slip, 5 points is stable); Rating Rules: Testers score independently after blind testing, remove the highest and lowest scores, and take the average. The total score is the average of the three dimensions, with a maximum score of 5 points. The higher the score, the better the feel.

[0067] Among them, mechanical performance testing was conducted:

[0068] Tensile permanent deformation test: The residual deformation of the sample after constant tension is measured, which reflects the elastic recovery ability of the material. The lower the deformation rate, the better the elasticity. Equipment: tensile testing machine; Standard: ISO2285-2013 "Rubber and plastics - Determination of tensile permanent deformation"; Conditions: temperature 25℃×24h, strain 100%, 5 samples per group, and the average value is taken.

[0069] Tensile strength and elongation at break test: Equipment: tensile testing machine; Standard: GB / T1040.3-2006 "Determination of tensile properties of plastics - Part 3: Test conditions for films and sheets"; Conditions: tensile speed 500 mm / min, temperature 23±2℃, 5 samples per group, average value is taken.

[0070] The durability test will be conducted as follows:

[0071] Friction and wear test: Simulate the surface condition changes after multiple uses, and evaluate durability by measuring the rate of decline in anti-slip performance after wear; Equipment: Martindale abrasion tester; Conditions: Load 12kPa, 500 cycles of friction (simulating the wear level of 6 months of normal use); Index: The ratio of the difference in static friction coefficient before and after wear to the initial friction coefficient (decay rate). The lower the decay rate, the better the durability.

[0072] Powder Residue Test (for Control Group 1 only): This test measures the amount of talc powder detached during use to evaluate surface stability. Procedure: The sample is fixed on a reciprocating friction device and rubbed 100 times under a 50N load. The detached powder is collected and weighed using an electronic balance (accuracy 0.1mg). The powder residue per unit area (mg / cm²) is calculated. 2 ).

[0073] Based on the above tests, the specific experimental results are shown in Table 1:

[0074] Table 1 Comparison of Experimental Test Data

[0075]

[0076]

[0077] As shown in Table 1, the static friction coefficients of all example groups were significantly higher than those of the control group. Among them, example group 3 had the best anti-slip performance, with the friction coefficient in the dry state being 81.9% higher than that of control group 1 and in the wet state being 92.6% higher. The embossed texture effectively solved the anti-slip shortcomings of traditional smooth products by increasing the surface contact area and friction, and it can still maintain a high friction coefficient in the wet state, which is suitable for actual use scenarios such as sweaty hands. Control group 1 relied on talcum powder to improve anti-slip performance, resulting in a lower initial friction coefficient, and the powder was easy to fall off, so it could not maintain the anti-slip effect for a long time. Meanwhile, in terms of gloss, both the Example Group and Control Group 2 maintained a low gloss of 15-25%, meeting the requirements for matte finish. However, Control Group 1, due to its glossy structure and the reflective properties of talcum powder, had a significantly higher gloss, resulting in a poorer visual texture. Regarding the feel score, the Example Groups all had an average score higher than 4.7. Example Group 3 received the highest score due to its delicate frosted texture and stable grip. Control Group 1 received the lowest score due to talcum powder residue and a sticky feel on the glossy surface (powder falls off after use). Although Control Group 2 had no stickiness, it lacked the grip stability of the embossed texture, resulting in a lower overall score than the Example Groups. Furthermore, in terms of tensile permanent deformation, both the Example Group and Control Group 2 had a deformation lower than 6.1%, significantly better than Control Group 1, indicating that the embossing process of this invention did not damage the structure of the base material and maintained high elasticity. In terms of tensile strength and elongation at break, the Example Group and Control Group 2 were similar, and both were higher than Control Group 1, indicating that the embossing treatment did not reduce the mechanical properties of the material, meeting the strength requirements of fitness equipment. Furthermore, regarding the rate of decline in anti-slip performance, all example groups showed a decline rate of less than 10%, with example group three exhibiting the lowest decline rate (6.8%), indicating that the embossed texture structure is stable and its anti-slip properties can be maintained even after long-term use. In contrast, control group one experienced a decline rate as high as 31.4% due to talcum powder shedding, while control group two, lacking an embossed structure, showed a significant decrease in anti-slip performance after surface wear. After 100 cycles of friction, the residual powder content per unit area in control group one decreased to 0.3 mg / cm². 2 The value was only 25% of the initial value, indicating that the talc powder was easy to fall off and could not maintain the anti-slip and dry effect for a long time. In contrast, the example group did not require powdering and the surface condition was stable.

[0078] In summary, the embossed structure of this invention can increase the static friction coefficient of TPE tension sheets by more than 60% and improve anti-slip performance by more than 50% in wet conditions, solving the anti-slip shortcomings of traditional glossy products and adapting to actual usage scenarios. Simultaneously, it offers excellent surface texture and feel; the example group maintains a low gloss level of 15-20% (matte effect), is non-sticky, has a delicate touch, and achieves a grip stability score higher than 4.7, significantly better than the control group. Furthermore, it exhibits stable mechanical properties; the embossing process does not damage the base material structure. The example group shows a tensile permanent deformation ≤6.1%, tensile strength ≥8.0MPa, and elongation at break ≥645%, maintaining high elasticity and high strength. Its durability is outstanding; the example group shows an anti-slip performance decay rate of less than 10%, no powder shedding, and stable performance after long-term use, while the control group shows an anti-slip performance decay rate exceeding 30%, easy powder shedding, and poor durability.

[0079] Therefore, this invention achieves breakthroughs in anti-slip properties, surface texture, mechanical properties, and durability through the structural design and supporting process of "matte high-elastic base layer combined with functional embossed layer". It is superior to existing mainstream products and has high practical value and market competitiveness.
