Description

A three-dimensional anti-slip composite dust-free paper Technical Field

[0001] This utility model relates to the field of dust-free paper technology, and in particular to a three-dimensional anti-slip composite dust-free paper. Background Technology

[0002] In the cleaning products industry, lint-free wipes, with their high absorbency, excellent softness, and dust-free properties, have become widely used wiping materials in various fields such as homes, medical facilities, and industry. However, traditional lint-free wipes often face the problem of insufficient anti-slip performance during use. Specifically, when the surface of the lint-free wipe remains smooth, but the user's hands become slippery due to moisture or oil, the friction between the lint-free wipe and the user's hands decreases significantly, causing the lint-free wipe to easily slip from the user's hand. This not only affects the user experience but may also lead to incomplete cleaning. In addition, the smooth surface of traditional lint-free wipes is not effective at cleaning some stubborn and strongly adhering stains. To solve this problem, some improved lint-free wipe products have appeared on the market, such as those that add coarse fibers to the surface of the lint-free wipe to increase its surface roughness and thus enhance its cleaning ability.

[0003] Based on the above, in the prior art, patent CN207452396U discloses a lint-free paper and air-laid composite wiping material, including lint-free paper and a low-melting-point fiber layer. The lint-free paper and the low-melting-point fiber layer are bonded and fixed by thermal bonding. The low-melting-point fiber layer uses fibers with a fineness of 10D-20D and a length of 3mm-8mm. The low-melting-point fibers are composed of at least one of PP, PE, PE / PP, and PE / PET fibers. The low-melting-point fiber layer is made by air-laid. The above-mentioned composite wiping material can maintain the use of lint-free paper as a wiping material while adding a layer of coarse-denier low-melting-point fibers, so that it can play a very good role in removing stubborn stains.

[0004] In the aforementioned composite material, an air-laid web layer composed of coarse denier low-melting-point fibers is thermally bonded to the surface of the lint-free paper to enhance friction with the clean surface, thereby improving the cleaning effect. At the same time, it also increases the anti-slip effect of the composite material to a certain extent. However, the composite material sacrifices the softness of the lint-free paper, or the low-melting-point fiber layer may fall off during long-term use and wear. The adhesive layer remaining on the surface of the lint-free paper may weaken its original cleaning performance. In addition, the composite material has the limitation of single functionality and is not sufficient to meet the cleaning needs of different environments and scenarios. Summary of the Invention

[0005] To address the technical deficiencies in the background art, this utility model proposes a three-dimensional anti-slip composite dust-free paper. To further solve the aforementioned technical problems and meet practical needs, the specific technical solution is as follows:

[0006] A three-dimensional anti-slip composite cleanroom paper includes an upper cleanroom paper body and a lower cleanroom paper body arranged parallel to each other. The upper cleanroom paper body has a first cleanroom paper composite layer, and the lower cleanroom paper body has a second cleanroom paper composite layer. A first adhesive film layer and a second adhesive film layer are arranged parallel to each other between the first and second cleanroom paper composite layers. The first adhesive film layer is disposed on the lower surface of the first cleanroom paper composite layer, and the second adhesive film layer is disposed on the upper surface of the second cleanroom paper composite layer. The upper surface of the first cleanroom paper composite layer is provided with first anti-slip layers at equal intervals, and the lower surface of the second cleanroom paper composite layer is provided with second anti-slip layers at equal intervals. The lower surface of the first adhesive film layer is provided with uniformly distributed protrusions, and the upper surface of the second adhesive film layer is provided with grooves that mate with the protrusions.

[0007] Furthermore, the first anti-slip layer includes a first adhesive layer and a plurality of first anti-slip particles uniformly distributed on the upper surface of the first adhesive layer, and the lower surface of the first adhesive layer is bonded to the upper surface of the first dust-free paper composite layer. The second anti-slip layer includes a second adhesive layer and a plurality of second anti-slip particles uniformly distributed on the lower surface of the second adhesive layer, and the upper surface of the second adhesive layer is bonded to the lower surface of the second dust-free paper composite layer.

[0008] Furthermore, the first anti-slip layer on the upper surface of the first dust-free paper composite layer and the second anti-slip layer on the lower surface of the second dust-free paper composite layer are respectively provided, and the distance between adjacent first anti-slip layers is 2.5-3cm, and the distance between adjacent second anti-slip layers is 2.5-3cm.

[0009] Furthermore, both the first adhesive layer and the second adhesive layer are polyurethane adhesive layers with a thickness of 100-150μm, the width of both the first adhesive layer and the second adhesive layer is 0.3-0.5cm, and the particle size of both the first anti-slip particles and the second anti-slip particles is 50-60μm.

[0010] Furthermore, the first and second anti-slip particles are any one of PU particles, TPU particles, and PET particles.

[0011] Furthermore, the first and second adhesive film layers are EVA adhesive film layers, the diameter of the bumps is 1-2 mm, and the distance between adjacent bumps is 3-5 mm.

[0012] Furthermore, the groove and the protrusion are fitted with a clearance, the diameter of the groove is 1.1-2.1mm, and the distribution position of the groove on the second adhesive film layer corresponds to the distribution position of the protrusion on the first adhesive film layer.

[0013] Furthermore, the first and second cleanroom paper composite layers have the same structure, both including a carbon fiber mesh layer, an antibacterial layer and a cleanroom paper layer arranged from the inside out. The upper surface of the first adhesive film layer is bonded to the carbon fiber mesh layer of the first cleanroom paper composite layer, and the lower surface of the second adhesive film layer is bonded to the carbon fiber mesh layer of the second cleanroom paper composite layer.

[0014] The beneficial effects of this utility model are as follows:

[0015] By introducing a first anti-slip layer and a second anti-slip layer corresponding to the upper and lower cleanroom paper bodies, the friction of the composite cleanroom paper surface can be effectively enhanced, preventing slippage during use. The first and second anti-slip particles make the composite cleanroom paper more effective at cleaning stubborn stains that are difficult to remove, effectively improving cleaning efficiency and results. By utilizing the protrusions and grooves between the first and second adhesive film layers, a stable combination of the upper and lower cleanroom paper bodies can be achieved. This allows users to use either body separately as needed, or easily combine them into a composite cleanroom paper when required, increasing the flexibility and convenience of use. The gap fit between the protrusions and grooves ensures the firmness of the combination. The combination of the carbon fiber mesh layer, antibacterial layer, and cleanroom paper layer in the cleanroom paper composite layer not only improves the strength and durability of the cleanroom paper, but also endows it with antibacterial properties, effectively inhibiting bacterial growth.

Detailed Implementation

[0018] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0019] As shown in Figure 1, this utility model provides a technical solution: a three-dimensional anti-slip composite dust-free paper, including an upper dust-free paper body 1 and a lower dust-free paper body 6 arranged parallel to each other. The upper dust-free paper body 1 is provided with a first dust-free paper composite layer 11, and the lower dust-free paper body 6 is provided with a second dust-free paper composite layer 61. A first adhesive film layer 4 and a second adhesive film layer 5 are arranged parallel to each other between the first dust-free paper composite layer 11 and the second dust-free paper composite layer 61. The first adhesive film layer 4 is disposed on the lower surface of the first dust-free paper composite layer 11, and the second adhesive film layer 5 is disposed on the upper surface of the second dust-free paper composite layer 61. A first anti-slip layer 2 is provided at equal intervals on the upper surface of the first dust-free paper composite layer 11, and a second anti-slip layer 3 is provided at equal intervals on the lower surface of the second dust-free paper composite layer 61. The lower surface of the first adhesive film layer 4 is provided with uniformly distributed protrusions 41, and the upper surface of the second adhesive film layer 5 is provided with grooves 51 that cooperate with the protrusions 41.

[0020] In the structure of this utility model, the first cleanroom paper composite layer 11 and the second cleanroom paper composite layer 61 have the same composition structure, both including a carbon fiber mesh layer 9, an antibacterial layer 8 and a cleanroom paper layer 7 arranged from the inside out. The upper surface of the first adhesive film layer 4 is bonded to the carbon fiber mesh layer 9 of the first cleanroom paper composite layer 11, and the lower surface of the second adhesive film layer 5 is bonded to the carbon fiber mesh layer 9 of the second cleanroom paper composite layer 61. The carbon fiber mesh layer 9, the antibacterial layer 8 and the cleanroom paper layer 7 are bonded together by an adhesive, thereby obtaining the corresponding first cleanroom paper composite layer 11 and the second cleanroom paper composite layer 61.

[0021] In the structure of this utility model, the first anti-slip layer 2 includes a first adhesive layer 21 and a plurality of first anti-slip particles 22 uniformly distributed on the upper surface of the first adhesive layer 21. The lower surface of the first adhesive layer 21 is bonded to the upper surface of the first dust-free paper composite layer 11. The second anti-slip layer 3 includes a second adhesive layer 31 and a plurality of second anti-slip particles 32 uniformly distributed on the lower surface of the second adhesive layer 31. The upper surface of the second adhesive layer 31 is bonded to the lower surface of the second dust-free paper composite layer 61.

[0022] The three-dimensional anti-slip composite dust-free paper of this utility model has an upper dust-free paper body 1 and a lower dust-free paper body 6 that are parallel to each other. Both of them have independent wiping functions, and can also be used in combination through protrusions 41 and grooves 51 to form a more robust wiping material.

[0023] Specifically, the upper dust-free paper body 1 includes a first dust-free paper composite layer 11, which consists of a dust-free paper layer 7, an antibacterial layer 8, and a carbon fiber mesh layer 9 from top to bottom, thereby ensuring the cleanliness of wiping with the upper dust-free paper body 1 and introducing antibacterial and reinforcing properties. On the upper surface of the first dust-free paper composite layer 11, a first anti-slip layer 2 is provided at equal intervals. This layer consists of a first adhesive layer 21 and a number of first anti-slip particles 22 evenly distributed thereon, thereby enhancing the anti-slip effect of the first anti-slip layer 2 during wiping and improving the cleaning ability against stubborn stains. A first adhesive film layer 4 is provided on the lower surface of the first dust-free paper composite layer 11, and the protrusions 41 evenly distributed on its lower surface are the connection structure with the lower dust-free paper body 6.

[0024] Correspondingly, the lower cleanroom paper body 6 includes a second cleanroom paper composite layer 61, which has the same structure as the first cleanroom paper composite layer 11. It also includes a cleanroom paper layer 7, an antibacterial layer 8, and a carbon fiber mesh layer 9. On the lower surface of the second cleanroom paper composite layer 61, a second anti-slip layer 3 is provided at equal intervals. This layer is composed of a second adhesive layer 31 and several second anti-slip particles 32 evenly distributed on its lower surface, forming an anti-slip and cleaning structure on the lower surface of the lower cleanroom paper body 6. The second adhesive film layer 5 is provided on the upper surface of the second cleanroom paper composite layer 61. The groove 51 cooperates with the protrusion 41 of the first adhesive film layer 4, realizing a stable connection between the upper cleanroom paper body 1 and the lower cleanroom paper body 6.

[0025] In the composite cleanroom of this utility model, the introduction of the first anti-slip layer 2 and the second anti-slip layer 3 in the structure, as well as the reinforcement of the first anti-slip particles 22 and the second anti-slip particles 32, increases the friction between the composite cleanroom paper and the wiping surface and the user's hand during the wiping process. This effectively prevents the composite cleanroom paper from slipping off the hand or shifting, improves the stability and efficiency of wiping, and makes the composite cleanroom paper exhibit stronger cleaning ability when facing stubborn stains.

[0026] The first anti-slip layer 2 and the second anti-slip layer 3, which are spaced apart, ensure that the surface of the composite cleanroom paper has anti-slip capability while also effectively exposing the cleanroom paper layer 7, thereby maintaining the cleaning ability of the composite cleanroom paper. Specifically, the first anti-slip layer 2 is set on the upper surface of the first cleanroom paper composite layer 11 of the upper cleanroom paper body 1, and the second anti-slip layer 3 is set on the lower surface of the second cleanroom paper composite layer 61 of the lower cleanroom paper body 6. Both are set at equal intervals, so that the first anti-slip layer 2 and the second anti-slip layer 3 do not completely cover the cleanroom paper layer 7 in the first cleanroom paper composite layer 11 and the second cleanroom paper composite layer 61. This maintains the softness of the cleanroom paper layer 7. During the wiping process, the first anti-slip layer 2 and the second anti-slip layer 3 can increase the friction with the wiping surface and the user's hand to prevent slippage, while the cleanroom paper layer 7 can directly contact the surface to be cleaned and perform its cleaning function.

[0027] As one of the preferred embodiments of this utility model, the first anti-slip layer 2 on the upper surface of the first dust-free paper composite layer 11 and the second anti-slip layer 3 on the lower surface of the second dust-free paper composite layer 61 are correspondingly arranged, and the distance between adjacent first anti-slip layers 2 and adjacent second anti-slip layers 3 is 2.5-3cm.

[0028] In one of the preferred embodiments of the present invention, the first adhesive layer 21 and the second adhesive layer 31 are both polyurethane adhesive layers with a thickness of 100-150μm, the width of the first adhesive layer 21 and the second adhesive layer 31 is 0.3-0.5cm, and the particle size of the first anti-slip particles 22 and the second anti-slip particles 32 is 50-60μm.

[0029] Specifically, the spacing between adjacent first anti-slip layers 2 and adjacent second anti-slip layers 3 is 3cm. The first adhesive layer 21 and the second adhesive layer 31 are both 150μm thick polyurethane adhesive layers, and the width of the first adhesive layer 21 and the second adhesive layer 31 is 0.3cm. The particle size of the first anti-slip particles 22 and the second anti-slip particles 32 is 60μm. The polyurethane adhesive has good adhesion and can firmly bond the first anti-slip particles 22 and the second anti-slip particles 32 to the first cleanroom paper composite layer 11 and the second cleanroom paper composite layer 61, respectively. At the same time, the polyurethane adhesive layer also has a certain degree of flexibility and can adapt to the slight deformation of the composite cleanroom paper during use, maintaining a tight fit between the first anti-slip layer 2, the second anti-slip layer 3 and the cleanroom paper layer 7, thereby ensuring the stable performance of anti-slip effect and cleaning ability.

[0030] As one of the preferred embodiments of this utility model, the first anti-slip particles 22 and the second anti-slip particles 32 are any one of PU particles, TPU particles, and PET particles. Specifically, the first anti-slip particles 22 and the second anti-slip particles 32 are applied to the first adhesive layer 21 and the second adhesive layer 31 that are coated on the surface of the dust-free paper layer 7 by means of spreading. The first anti-slip particles 22 and the second anti-slip particles 32 are preferably PU particles. PU particles have good elasticity and can provide soft and effective friction during wiping. At the same time, they are highly wear-resistant and not easily worn after long-term use, thus maintaining the anti-slip effect and the cleaning effect on stubborn stains.

[0031] In one of the preferred embodiments of this utility model, the first adhesive film layer 4 and the second adhesive film layer 5 are EVA adhesive film layers, the diameter of the protrusion 41 is 1-2mm, and the distance between adjacent protrusions 41 is 3-5mm.

[0032] As one of the preferred embodiments of this utility model, the groove 51 and the protrusion 41 are in clearance fit, the diameter of the groove 51 is 1.1-2.1mm, and the distribution position of the groove 51 on the second adhesive film layer 5 corresponds to the distribution position of the protrusion 41 on the first adhesive film layer 4.

[0033] Specifically, the diameter of the protrusion 41 is 2mm, the diameter of the groove 51 is 2.1mm, the distance between adjacent protrusions 41 is 5mm, the first adhesive layer 4 and the second adhesive layer 5 are EVA adhesive layers. The EVA adhesive layer has excellent flexibility and weather resistance, and can maintain the overall softness of the composite cleanroom paper when the upper cleanroom paper body 1 and the lower cleanroom paper body 6 are laminated.

[0034] The grooves 51 on the second adhesive film layer 5 and the protrusions 41 on the first adhesive film layer 4 can be fabricated using an embossing process. Using an embossing device, grooves 51 are pressed into the surface of the second adhesive film layer 5, and protrusions 41 are pressed into the first adhesive film layer 4.

[0035] The gap fit between the protrusion 41 and the groove 51 enables accurate positioning between the upper cleanroom paper body 1 and the lower cleanroom paper body 6, ensuring a tight fit when used together and preventing displacement or detachment. It also provides a degree of fixation, enhancing the overall stability of the composite cleanroom paper.

[0036] 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 principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
