Description

Technical Field

[0001] This utility model relates to the field of base surface covering roll material technology, specifically to an adhesive anti-slip flooring and anti-slip components. Background Technology

[0002] Floor mats are floor decoration materials primarily made of plastic, mainly used in hospitals, schools, office buildings, laboratories, commercial spaces, and homes. Air bridges, also known as boarding bridges, are passageways extending from the boarding gate to the cabin door, facilitating passenger access. Air bridge floors are typically made of metal, such as iron. Since air bridges are used outdoors, the ground can become slippery due to icing in low temperatures. To improve friction between passengers' shoes and the air bridge floor, non-slip floor mats are usually laid on the ground. The bottom surface bonded to the air bridge is usually made of pressure-resistant plastic.

[0003] Taking metal-based covered walkways as an example, existing adhesive flooring has the following drawbacks: First, the plastic material has a smooth surface or is embossed. The plastic material is bonded to the metal base with an adhesive. The bonding interface between the adhesive and the plastic material is limited, resulting in low peel strength. Secondly, after prolonged use at high and low temperatures, the plasticizers inside the plastic material are prone to migrate to the cured adhesive layer, reducing the peel strength between the adhesive layer and the substrate. Third, the dimensional stability and warping suppression performance of the flooring mainly rely on the embedded reinforcement layer. Since the covered bridge is used outdoors, the temperature difference in the environment is large, resulting in poor dimensional stability of the flooring. Utility Model Content

[0004] One of the objectives of this invention is to overcome the defects in the existing technology and provide an adhesive anti-slip floor mat. By setting a bottom cloth layer including an embedding part and a bonding part on the bottom surface of the floor mat, the bonding strength and durability between the floor mat and the metal base surface are improved.

[0005] To achieve the above-mentioned technical effects, the technical solution of this utility model is as follows: an adhesive anti-slip flooring, comprising a wear-resistant surface layer and a pressure-resistant bottom layer stacked on top of each other, wherein the wear-resistant surface layer is embedded with anti-slip particles, and the pressure-resistant bottom layer is provided with a base fabric layer, wherein the base fabric layer includes an embedded part and a part to be bonded that are stacked and integrally connected along the thickness direction, the embedded part is immersed in the pressure-resistant bottom layer, and the part to be bonded is covered on the surface of the pressure-resistant bottom layer that is away from the wear-resistant surface layer.

[0006] The preferred technical solution is that the bottom fabric layer is a spunlace nonwoven fabric.

[0007] A preferred technical solution is that the thickness of the base fabric layer is 0.15 to 1.2 mm.

[0008] A preferred technical solution is that the basis weight of the base fabric layer is 50–170 g / m².2 .

[0009] A preferred technical solution is that the pressure-resistant bottom layer is embedded with a fiber aggregate reinforcement layer.

[0010] A preferred technical solution is that the fiber aggregate reinforcement layer and the embedded part are spaced apart from each other along the thickness direction of the floor adhesive.

[0011] A preferred technical solution is that the thickness ratio of the embedded part to the part to be bonded is 1:(0.5~5).

[0012] A preferred technical solution is that the bottom fabric layer is PET fiber nonwoven fabric, and / or the substrate resin of the wear-resistant surface layer and / or the pressure-resistant bottom layer is PVC.

[0013] The second objective of this utility model is to provide an anti-slip component, including a base with a bonding surface and the aforementioned adhesive anti-slip flooring. The adhesive anti-slip flooring is bonded to the bonding surface through an adhesive layer, and at least a portion of the part to be bonded is immersed in the adhesive layer along the thickness direction.

[0014] The preferred technical solution is that the bonding surface is made of metal.

[0015] The advantages and beneficial effects of this utility model are as follows: The embedded part of the adhesive anti-slip floor mat base layer is located inside the pressure-resistant bottom layer. Compared with the plastic surface, the bonding interface between the part to be bonded and the adhesive is greatly increased. The entanglement between the fibers inside the non-woven fabric is superimposed, which improves the peel strength of the adhesive structure of the floor mat. The fibers of non-woven fabrics block the migration of plasticizers into adhesives, delay the adverse effects of plasticizers on the peel strength of the bonded structure, and enhance the durability of the floor mat. The non-woven fabric embedding helps improve the dimensional stability of the floor mat, reduce heat warping, and extend the product's lifespan under extreme weather conditions.

[0017] The specific embodiments of this utility model will be further described below with reference to the examples. These examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0018] In the description of this application, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating orientation or positional relationship are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0019] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] In the description of this utility model, terms such as "first" and "second" are used to distinguish different objects, rather than to describe a specific order or primary / secondary relationship. Example

[0021] like Figure 1-3 As shown, the adhesive anti-slip flooring in this embodiment includes a wear-resistant surface layer 1 and a pressure-resistant bottom layer 2 that are stacked on top of each other. The wear-resistant surface layer 1 is embedded with anti-slip particles 3. The pressure-resistant bottom layer 2 is provided with a base fabric layer 4. The base fabric layer 4 includes an embedded part 401 and a part to be bonded 402 that are stacked and integrally connected along the thickness direction. The embedded part 401 is immersed in the pressure-resistant bottom layer 2, and the part to be bonded 402 is covered on the surface of the pressure-resistant bottom layer 2 that is away from the wear-resistant surface layer 1.

[0022] Both the wear-resistant surface layer 1 and the pressure-resistant bottom layer 2 are made of plastic, and their polymer substrates can be the same or different. The wear-resistant surface layer 1 has the ability to resist mechanical wear, while the pressure-resistant bottom layer 2 has the ability to resist deformation under heavy pressure. The polymer substrate includes, but is not limited to, PVC, rubber, EVA, epoxy resin, and other materials known for use in floor mats. It is understood that the above-mentioned polymer substrate can be a pure polymer material or a polymer material with added fillers, leveling agents, defoamers, plasticizers, and other additives.

[0023] The wear-resistant surface layer 1 is embedded with anti-slip particles 3, including but not limited to the following structures: ① The anti-slip particles 3 are embedded only in the wear-resistant surface layer 1, and the wear-resistant surface layer 1 has a wear-resistant surface that is away from the pressure-resistant bottom layer 2; the anti-slip particles 3 are spaced apart from the wear-resistant surface, that is, the anti-slip particles 3 are located below the wear-resistant surface, or at least some of the anti-slip particles 3 are in contact with the wear-resistant surface (including line contact, surface contact and point contact), or at least some of the anti-slip particles 3 protrude from the wear-resistant surface; ② The anti-slip particles 3 are partially embedded in the wear-resistant surface layer 1 and partially embedded in the pressure-resistant bottom layer 2. The relative positional relationship between the anti-slip particles 3 and the wear-resistant surface is the same as in point ① above, and will not be repeated here.

[0024] Understandably, in terms of production process, anti-slip particles 3 can be produced by blending with the base plastic to form sheets, or by spreading anti-slip particles 3 onto the plastic after it has been coated or scraped into sheets.

[0025] In the specific structure of the aforementioned floor mat and anti-slip particles 3, preferably, at least some of the anti-slip particles 3 have their friction-enhancing tips in contact with the textured surface. The friction-enhancing tips are closer to or exposed on the floor mat surface, utilizing the difference in material deformation between the anti-slip particles 3 and the wear-resistant surface layer 1 under pressure to increase the friction of the floor mat surface. Further, the wear-resistant surface is a textured surface. The proportion of anti-slip particles 3 in the total amount of anti-slip particles 3 in the floor mat is controlled to be relatively large. Unlike floor mat surfaces where the friction-enhancing tips of the anti-slip particles 3 are flush with the wear-resistant surface layer 1, the specific preparation method includes the following steps: maintaining the wear-resistant surface layer 1 and the pressure-resistant bottom layer 2 in a softened state, spreading the anti-slip particles 3 onto the wear-resistant surface layer 1 and the pressure-resistant bottom layer 2, and then embossing the surface of the wear-resistant surface layer 1. Compared to directly blending the anti-slip particles 3 with a polymer substrate to obtain a sheet, the above production process is beneficial for increasing the percentage of particles with friction-enhancing tips in contact with the textured surface in the total number of particles. Except for the anti-slip particles 3 whose friction-enhancing tips are in contact with the textured surface, the friction-enhancing tips of the other anti-slip particles 3 are located within the wear-resistant surface layer 1, and the distance between them and the textured surface is controlled to be small. This distance is caused by the settling of the anti-slip particles 3 in the softened wear-resistant surface layer 1 / pressure-resistant bottom layer 2. In addition, in floor mats where the anti-slip particles 3 are first mixed with plastic material to form a sheet and then embossed, the anti-slip particles 3 are randomly distributed in the thickness direction of the floor mat; while in floor mats obtained by first spreading the anti-slip particles 3 and then embossing them, more friction-enhancing tips of the anti-slip particles 3 contact the floor mat surface, making full use of the anti-slip particles 3 and achieving the desired anti-slip effect.

[0026] The anti-slip particles 3 have a significant difference in hardness compared to the plastic substrate in which they are embedded. Specifically, the anti-slip particles 3 are made of inorganic materials, metals, or polymers; for example, single-compound inorganic particles such as silicon dioxide, silicon carbide, silicon nitride, aluminum oxide, aluminum nitride, and boron nitride, or crushed particles of natural inorganic materials, or inorganic particles made by firing kaolin, feldspar, quartz, clay, etc.; the aforementioned polymers can be selected from PET particles, polyetheretherketone particles, etc., which have been reinforced by fillers, etc., and are preferably inorganic particles.

[0027] In the context of the pressure-resistant underlayer 2 and the wear-resistant surface layer 1, the term "bottom" indicates the vertical positional relationship, which is related to the location of the substrate on which the flooring is applied. When the flooring is applied to a conventional substrate facing upwards, the pressure-resistant underlayer 2 is positioned close to the substrate, such as a walkway, while the wear-resistant surface layer 1 is positioned away from the substrate. Compared to the pressure-resistant underlayer 2, the surface of the wear-resistant surface layer 1 is closer to the soles of passengers' shoes and the wheel surfaces of luggage. Correspondingly, the term "top" in the friction-enhancing tip of the anti-slip particles 3 also indicates the vertical positional relationship. The friction-enhancing tip refers to the end that is close to the soles of passengers' shoes and the wheel surfaces of luggage to increase friction. It can be understood that when the flooring is fixed to a substrate facing downwards, the vertical positional relationship of the pressure-resistant underlayer 2 and the wear-resistant surface layer 1 is reversed, but the proximity or distance between the pressure-resistant underlayer 2 and the wear-resistant surface layer 1 and the substrate remains unchanged.

[0028] Optional, such as Figure 1 As shown, the average particle size of the anti-slip particles 3 is equal to, less than or greater than the thickness of the wear-resistant surface layer 11; the materials of the pressure-resistant bottom layer 2 and the wear-resistant surface layer 1 can be the same material that has both pressure resistance and wear resistance.

[0029] The base fabric layer 4 can be selected from spunlace nonwoven fabric, thermally bonded nonwoven fabric, and needle-punched nonwoven fabric according to the production process. The embedded part 401 of the base fabric layer 4 is set in the pressure-resistant bottom layer 2 and can be obtained by the following process: the pressure-resistant bottom layer 2 material is coated onto the surface of the base fabric layer 4. The fluid pressure-resistant bottom layer 2 material falls to the fibers below the surface of the base fabric layer 4 due to its own weight. As the temperature of the pressure-resistant bottom layer 2 material gradually decreases, its fluidity and falling depth in the nonwoven fabric are controlled by adjusting the temperature and other parameters of the pressure-resistant bottom layer 2 material. Finally, the pressure-resistant bottom layer 2 material gradually solidifies and covers the surface of the fibers of the embedded part 401.

[0030] In some preferred embodiments, the base fabric layer 4 is a spunlace nonwoven fabric.

[0031] In some preferred embodiments, the thickness of the base fabric layer 4 is 0.15–1.2 mm, a further thickness is 0.25–0.9 mm, and an even further thickness is 0.3–0.75 mm. If the thickness of the base fabric layer 4 is too thick, the adhesive may not be fully impregnated in the layer to be bonded, resulting in a weak adhesive bond. If the thickness of the base fabric layer 4 is too thin, it is easily completely impregnated by the pressure-resistant undercoat 2, making it impossible to obtain the desired thickness of the bonding portion 402.

[0032] In some preferred embodiments, the basis weight of the base fabric layer 4 is 50–170 g / m². 2 Further weight is 70–150 g / m³. 2 Furthermore, the basis weight is 80–140 g / m³. 2 For the same thickness, if the basis weight of the base fabric layer 4 is too large, the fiber distribution and entanglement in the base fabric layer 4 will be more compact, and the coated plastic and adhesive will not be easy to wet and penetrate. If the basis weight of the base fabric layer 4 is too small, it will be easily completely soaked by the coated pressure-resistant underlayer 2, and the desired thickness of the bonding part 402 cannot be obtained.

[0033] like Figure 4 As shown, in another preferred embodiment, the pressure-resistant bottom layer 2 is embedded with a fiber aggregate reinforcement layer 5. The fiber aggregate reinforcement layer 5 works together with the bottom fabric layer 4 to improve the dimensional stability and heat resistance of the floor mat.

[0034] The fiber aggregate reinforcement layer 5 is a layered structure composed of fiber aggregates, which can be selected as woven or non-woven fabrics, including but not limited to non-woven fabrics, interwoven fabrics with through-holes in the thickness direction, and densely woven fabrics without through-holes in the thickness direction. The function of the fiber aggregate reinforcement layer 5 is to reinforce the floor mat, improving its dimensional stability and overall strength. It is understood that the type of fiber is selected specifically according to the function of the reinforcement layer, including but not limited to high and low temperature resistant fiber materials, such as glass fiber, carbon fiber, basalt fiber, aramid fiber, and bamboo fiber. According to the reinforcement layer structure, the fiber aggregate reinforcement layer 5 can be selected as a two-dimensional or three-dimensional structure. Taking a woven structure as an example, a two-dimensional woven structure has warp fiber bundles and weft fiber bundles, while a three-dimensional woven structure has warp fiber bundles, weft fiber bundles, and normal fiber bundles. Furthermore, the fiber aggregate reinforcement layer 5 is a warp and weft interwoven fabric to give the floor mat excellent dimensional stability against high and low temperatures.

[0035] It is understandable that the number of layers of the fiber aggregate reinforcement layer 5 in the pressure-resistant bottom layer 2 can be one or more. When the number of layers of the fiber aggregate reinforcement layer 5 is two or more, the materials of the layers of the fiber aggregate reinforcement layer 5 can be the same or different.

[0036] like Figure 4As shown, in another preferred embodiment, the fiber aggregate reinforcement layer 5 and the embedded portion 401 are spaced apart from each other along the thickness direction of the floor adhesive.

[0037] Understandably, the core layer of the pressure-resistant underlayer 2 is filled between the fiber aggregate reinforcement layer 5 and the embedded portion 401 along the thickness direction of the floor mat. In actual production, the pressure-resistant underlayer 2 consists of at least three unit pressure-resistant layers. The cured core layer provides a coating substrate for the unit pressure-resistant layers above it, and the fiber aggregate reinforcement layer 5 is laid on the surface of the coating substrate. Compared with the adjacent structure of the fiber aggregate reinforcement layer 5 and the embedded portion 401, the two-layer spacing can effectively avoid introducing too many interlayer pores between the fiber aggregate reinforcement layer 5 and the embedded portion 401, thereby improving the interlayer peel strength of the floor mat.

[0038] In some preferred embodiments, the thickness ratio of the embedding portion 401 to the portion to be bonded 402 is 1:(0.5 to 5), more preferably 1:(0.8 to 4). The thickness ratio of the embedding portion to the portion to be bonded is further determined based on the specifications of the nonwoven fabric, its affinity with the adhesive, the type of adhesive, etc.

[0039] In some preferred embodiments, the base fabric layer 4 is a PET fiber nonwoven fabric, and / or the substrate resin of the abrasion-resistant surface layer 1 and / or the pressure-resistant bottom layer 2 is PVC. The pressure-resistant bottom layer 2 is coated onto the surface of the base fabric layer 4 in the form of a resin paste; the fiber aggregate reinforcement layer 5 is coated on the pressure-resistant bottom layer 2 resin paste with a predetermined fluidity; the anti-slip particles 3 are sprinkled on the abrasion-resistant surface layer 1 resin paste and then settle due to their own weight.

[0040] like Figure 5 As shown, the anti-slip component of the embodiment includes a base 6 with a bonding surface, and also includes an adhesive anti-slip flooring adhesive as described in the above embodiment. The adhesive anti-slip flooring adhesive is bonded to the bonding surface through an adhesive layer 7. At least a portion of the part to be bonded 402 along the thickness direction is immersed in the adhesive layer 7. Further, the part to be bonded 402 is completely immersed in the adhesive layer 7.

[0041] Examples and Comparative Examples The anti-slip, stain-resistant, and dirt-resistant flooring in this embodiment adopts a production process of first spreading anti-slip particles 3 and then embossing. The main components of the wear-resistant surface layer 1 are PVC (Formosa Plastics 1069, 1704) and plasticizers, and the main components of the pressure-resistant bottom layer 2 are PVC (Formosa Plastics 440, 1302), plasticizers, and fillers. The anti-slip particles 3 are composed of quartz sand (160 g / m², 16, 18, 20 mesh quartz sand gradation) and 30 mesh corundum (120 g / m²). The wear-resistant surface layer 1 has a thickness of 0.5 mm, the pressure-resistant bottom layer 2 has a thickness of 2.4-2.5 mm, the fiber aggregate reinforcement layer 5 is 75 g / m² fiberglass cloth, and the base fabric layer uses the following three types of non-woven fabrics: Example 1: Needle-punched nonwoven fabric, basis weight 120 g / m2 Thickness 0.5mm, embedding part thickness 0.1mm, and part to be bonded thickness 0.4mm; Example 2: Spunlace nonwoven fabric, basis weight 120 g / m 2 Thickness 0.5mm, embedding part thickness 0.1mm, and part to be bonded thickness 0.4mm; Example 3: Thermally rolled nonwoven fabric, weight 120 g / m² 2 Thickness 0.35mm, embedding part thickness 0.1mm, and part to be bonded thickness 0.25mm; Comparative example: The bottom surface of the pressure-resistant underlayer is PVC, which is made by coating the PVC pressure-resistant underlayer material onto the surface of the release film.

[0042] Example and comparative performance testing: 1. The same two-component polyurethane adhesive (450g / m²) was used for the flooring samples of the examples and comparative examples. 2 The adhesive is bonded to the surface of the iron sheet, and after the adhesive has cured, the peel strength between the floor adhesive and the iron sheet is tested according to GB / T11982. 2. The heat warpage of the flooring in Example 1 and the comparative example was tested according to ISO 23999:2021; 3. The dimensional stability of the flooring in Example 1 and the comparative example was tested according to ISO 23999:2021.

[0043] Test results of sample performance: 1. The peel strength of Example 1 is 61 N / 50 mm; The peel strength of Example 2 was 100 N / 50 mm; The peel strength of Example 3 was 73 N / 50 mm; The peel strength of the comparative example is 30 N / 50 mm; 2. Example 1: Initial warpage: 0.0 mm, final warpage: 2.0 mm; Comparative Example 1: Heating warpage: 0.0 mm, Final warpage: 6.0 mm; 3. Dimensional stability of Example 1: 0.06% in the X direction and 0.06% in the Y direction. Comparative Example 1: Dimensional stability: 0.11% in the X direction and 0.14% in the Y direction.

[0044] The above data indicate that the bottom layer is preferably a spunlace nonwoven fabric with a predetermined thickness and weight range; the bottom layer improves the heating warpage and dimensional stability of the floor mat.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
