Description

Technical Field

[0001] The present invention relates to the technical field of household items, and particularly to a multi-layer composite anti-slip mat.

Background Art

[0002] Mat products such as sheet mats, floor mats, mattresses, and pet mats are widely used in various household scenes for the purpose of providing comfort and anti-slip functions.

[0003] However, the applicant has discovered that the prior art mat products have at least the following technical problems.

[0004] 1. The multi-layer materials of conventional mats are mainly fixed by adhesives. However, this fixing method is likely to cause peeling and cracking when used for a long time or subjected to external forces, which affects the structural stability and service life of the mats.

[0005] 2. Existing mats are mainly sewn by sewing machines or hand-sewing in the production process. Inevitably, pinholes are generated, which become water channels, making the inner layer of the mat easily absorb moisture and prone to mold growth. This not only shortens the service life of the mat but also poses a potential threat to the health of users. In addition, hand-sewing is inefficient, the quality of the finished product is unstable, and defective products are likely to occur.

[0006] 3. The bottom of conventional mats is usually coated with silicon or rubber to enhance the anti-slip effect. However, due to aging during long-term use, the coating is likely to peel off, affecting the anti-slip performance of the mat and potentially causing safety hazards. From such a perspective, the present invention is proposed.

However, the drawings in the following description are only some embodiments of the present invention, and it is obvious that those skilled in the art can obtain other drawings based on these drawings without creative labor.

Embodiments for Carrying out the Invention

[0019] In order to make the object, technical solution and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. It is obvious that the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present invention.

[0020] The present invention provides a multi-layer composite anti-slip mat including a surface layer, a filling layer, and a bottom layer laminated by hot melt pressure bonding. The surface layer includes a knitted layer, a woven layer, a non-woven fabric layer or a PU composite fabric layer. The filling layer includes a sponge layer or a flocked layer. The bottom layer includes a non-woven fabric layer laminated by hot melt pressure bonding and an adhesive layer.

[0021] In the present invention, the surface layer, the filling layer, and the bottom layer are subjected to hot melt pressure bonding by a high-frequency hot melt pressure bonding device. Under high temperature and high pressure, the material molecules between the surface layer, the filling layer, and the bottom layer penetrate and fuse with each other to form a strong bond, thereby effectively avoiding the peeling and cracking of the adhesive due to long-term use or external force, improving the structural stability of the mat, and extending the service life of the mat.

[0022] As the uppermost layer of the mat, the surface layer is in direct contact with the user. The surface layer includes a knitted layer, a woven layer, a non-woven fabric layer or a PU composite fabric layer. Here, the knitted layer, the woven layer, and the non-woven fabric layer may be formed by an appropriate weaving process using 100% natural fiber, synthetic fiber, or a mixed fiber mixed at a predetermined ratio, providing a soft and comfortable touch, increasing the frictional force between the user's feet, and improving the anti-slip performance.

[0023] The PU composite floor layer is formed by combining a polyurethane material and a fabric through a coating or laminating process. Since the polyurethane material has excellent waterproof performance, the PU composite floor layer can effectively prevent moisture from penetrating from the surface layer into the interior of the mat. Also, the PU composite floor layer has good abrasion resistance and elasticity and is resistant to frequent friction by users. Furthermore, the surface of the PU composite floor layer is smooth and easy to maintain.

[0024] The filling layer, as the middle layer of the mat, serves as a buffer and support. The filling layer includes a sponge layer or a flocked layer. The sponge layer is made of a low-rebound sponge, which has viscoelastic properties, can effectively absorb the pressure transmitted from the user, provide a very small rebound force to the user, and has an excellent buffering effect. Also, it has a soft touch, can provide sufficient support to the user, and can improve the comfort during use.

[0025] The flocked layer is made of a sheet-like cotton material, has excellent softness, can effectively absorb and disperse the pressure transmitted from the user, can provide comfortable support and buffering, and has a low production cost.

[0026] The bottom layer, as the lowermost layer of the mat, is in direct contact with the ground. The bottom layer includes a non-woven fabric layer and an adhesive layer fused by hot pressing from top to bottom. Here, the non-woven fabric layer has excellent air permeability and abrasion resistance, can improve the structural stability of the mat, and also provides a flat adhesion surface for the filling layer and the adhesive layer, improving the connection stability and reliability between layers.

[0027] The adhesive layer is made of a material with excellent adhesiveness, can firmly attach the mat to the desired ground position, and prevent it from slipping or shifting.

[0028] Due to the fusion of the mat layers by hot pressing, there are no gaps at the connection points, and the waterproof property is significantly improved.

[0029] Furthermore, since the mat is manufactured by a composite connection process using a hot melt pressure bonding process, the production time is significantly shortened and the production efficiency is improved compared to sewing by machine or by hand.

[0030] As a possible embodiment, the adhesive layer includes a TPE layer or a TPU layer.

[0031] The TPE layer is made of a thermoplastic elastomer and has excellent adhesiveness, so it can adhere firmly to the ground or other contact surfaces. Also, since it has excellent elasticity, it improves the cushioning effect of the mat.

[0032] The TPU layer is made of a thermoplastic polyurethane material and has excellent adhesiveness, so it can adhere firmly to the ground or other contact surfaces. Also, since it has excellent abrasion resistance, it extends the service life of the mat.

[0033] As a possible embodiment, the thickness of the surface layer is 0.1 mm to 2 mm.

[0034] The thickness of the surface layer can be flexibly adjusted according to specific usage requirements in order to adapt to various application scenarios.

[0035] As a possible embodiment, the filling layer has a thickness of 0.5 mm to 40 mm and a density of 2 kg / m 3 ~100 kg / m 3 and is.

[0036] The thickness and density of the filling layer can be flexibly adjusted according to specific usage requirements in order to adapt to various application scenarios.

[0037] As a possible embodiment, the non-woven fabric layer has a thickness of 0.3 mm to 10 mm and a basis weight of 30 g / m 2 ~1000 g / m 2 and is.

[0038] The thickness and basis weight of the non-woven fabric layer can be flexibly adjusted according to specific usage requirements in order to adapt to various application scenarios.

[0039] As a possible embodiment, the thickness of the adhesive layer is 1.5 mm to 2 mm.

[0040] The thickness of the adhesive layer can be flexibly adjusted according to specific usage requirements in order to adapt to various application scenarios.

[0041] As a possible embodiment, the edge of the mat is integrally formed by die-cutting.

[0042] With such a configuration, the flatness of the edge of the mat can be ensured, and the appearance of the entire mat can be improved.

[0043] Example 1 As shown in Figure 1, the present invention provides a multi-layer composite anti-slip mat specially designed for outdoor sheet cushions, including a surface layer, a filling layer, and a bottom layer laminated by hot melt pressure bonding. The surface layer includes a PU composite fabric layer 2, the filling layer includes a sponge layer 3, and the bottom layer includes a non-woven fabric layer 5 and an adhesive layer that are compounded and connected from top to bottom by a hot melt pressure bonding process. The adhesive layer includes a TPU layer 7.

[0044] Furthermore, the size of the mat is 40 cm × 40 cm. The thickness of the PU composite fabric layer 2 is 0.5 mm. The sponge layer 3 has a thickness of 10 mm and a density of 15 kg / m 3 It is. The non-woven fabric layer 5 has a thickness of 2 mm and a basis weight of 190 / m 2 It is. The thickness of the TPU layer 7 is 1.5 mm.

[0045] The PU composite fabric layer 2, the sponge layer 3, the non-woven fabric layer 5, and the TPU layer 7 are subjected to hot melt pressure bonding by a high-frequency hot melt pressure bonding device. Due to high temperature and high pressure, the material molecules between adjacent layers penetrate and fuse with each other to form a strong bond, thereby effectively avoiding the peeling and cracking of the adhesive caused by long-term use or external forces, improving the structural stability of the mat, and extending the service life of the mat.

[0046] The PU composite floor layer 2 is in direct contact with the user as the topmost layer of the mat. The PU composite floor layer is formed by combining a polyurethane material and a fabric through a coating or laminating process. Since the polyurethane material has excellent waterproof performance, the PU composite floor layer can effectively prevent moisture from penetrating from the surface layer into the interior of the mat. Also, the PU composite floor layer has good abrasion resistance and elasticity and is resistant to frequent friction by the user. Furthermore, the surface of the PU composite floor layer is smooth and easy to maintain.

[0047] The sponge layer 3 serves as the middle layer of the mat, providing a buffering and supporting function. The sponge layer 3 is made of a low-rebound sponge, which has viscoelastic properties, can effectively absorb the pressure transmitted from the user, provides a very small reaction force to the user, and has an excellent buffering effect. Also, it has a soft touch, can provide sufficient support to the user, and can improve the comfort during use.

[0048] The non-woven fabric layer 5 has excellent air permeability and abrasion resistance, can improve the structural stability of the mat, and provides a flat adhesion surface for the filling layer and the adhesive layer, improving the connection stability and reliability between layers.

[0049] The TPU layer 7 is in direct contact with the ground as the bottommost layer of the mat, can prevent the mat from slipping or shifting and firmly adhere the mat to the desired position on the ground. The TPU layer 7 is made of a thermoplastic polyurethane material and has excellent adhesiveness, so it can firmly adhere to the ground or other contact surfaces. Also, it has excellent abrasion resistance, extending the service life of the mat.

[0050] Furthermore, since the mat is manufactured through a composite connection process by a heat fusion pressing process, compared with sewing by machine or hand, the production time is significantly shortened and the production efficiency is improved.

[0051] As a possible embodiment, the edge of the mat is formed in one piece by die-cutting.

[0052] With such a configuration, it is possible to ensure the flatness of the edge of the mat and improve the appearance of the entire mat.

[0053] When tested according to the ASTM D1894 test standard, the coefficient of static friction of the adhesive layer in this example is 0.8 or more, thereby ensuring the anti-slip performance of the mat.

[0054] Due to the fusion of the mat layers by hot pressure bonding, there are no gaps at the connection points, and the waterproof performance is significantly improved. When tested according to the ISO 811 test standard, the water pressure resistance of the mat is 5000 Pa or more.

[0055] Example 2 As shown in FIG. 2, the present invention provides a multi-layer composite anti-slip mat specially designed for pet floor mats, including a surface layer, a filling layer, and a bottom layer laminated by hot melt pressure bonding. The surface layer includes a tuft layer 1, the filling layer includes a flocked layer 4, and the bottom layer includes a non-woven fabric layer 5 and an adhesive layer that are compounded and connected from top to bottom by a hot melt pressure bonding process. The adhesive layer includes a TPE layer 6.

[0056] Furthermore, the size of the mat is 60 cm × 90 cm. The thickness of the tuft layer 1 is 1.2 mm. The flocked layer 4 has a thickness of 8 mm and a density of 30 kg / m 3 is. The non-woven fabric layer 5 has a thickness of 3 mm and a basis weight of 290 g / m 2 is. The thickness of the TPE layer 6 is 2.0 mm.

[0057] The tuft layer 1, the flocked layer 4, the non-woven fabric layer 5, and the TPE layer 6 are subjected to hot melt pressure bonding by a high-frequency hot melt pressure bonding device. Due to high temperature and high pressure, the material molecules between adjacent layers penetrate and fuse with each other to form a strong bond, thereby effectively avoiding the peeling and cracking of the adhesive caused by long-term use or external forces, improving the structural stability of the mat, and extending the service life of the mat.

[0058] The tuft layer 1 is a knitted layer, which, as the topmost layer of the mat, comes into direct contact with the user. The tuft layer 1 forms a high-density suede layer on the surface by fixing plush yarns to the base fabric through tufting, providing a soft and comfortable touch, increasing the frictional force between the user's feet, and not only improving the anti-slip performance.

[0059] The flocked layer 4, as the middle layer of the mat, serves as a buffer and support. The flocked layer 4 is made of a sheet-like cotton material, has excellent softness, can effectively absorb and disperse the pressure transmitted from the user, can provide comfortable support and buffering, and has a low production cost.

[0060] The non-woven fabric layer 5 has excellent air permeability and wear resistance, can improve the structural stability of the mat, and also provides a flat adhesion surface for the filling layer and the adhesive layer, improving the connection stability and reliability between layers.

[0061] The TPE layer 6, as the bottommost layer of the mat, comes into direct contact with the ground, enables the mat to adhere firmly to the desired position on the ground, and can prevent slipping and displacement. The TPE layer 6 is made of a thermoplastic elastomer and has excellent adhesiveness, so it can adhere firmly to the ground and other contact surfaces. Moreover, it also has excellent elasticity, thus improving the cushioning effect of the mat.

[0062] Furthermore, since the mat is manufactured by a composite connection process through a hot melt pressure bonding process, compared with sewing by machine or hand, the production time is significantly shortened and the production efficiency is improved.

[0063] As a possible embodiment, the edge of the mat is integrally formed by die-cutting.

[0064] With such a configuration, the flatness of the edge of the mat can be ensured, and the appearance of the whole mat can be improved.

[0065] When tested in accordance with ASTM D1894 test standard, the static friction coefficient of the adhesive layer of this example is 0.8 or more, thereby ensuring the anti-slip performance of the mat.

[0066] Due to the fusion of the mat layers by hot pressing, there are no gaps at the connection points, and the waterproof property is significantly improved. When tested in accordance with ISO 811 test standard, the water pressure resistance of the mat is 5000 Pa or more.
