Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, specifically to a foam adhesive tape. Background Technology

[0002] Foam tape is used in many fields such as industrial production, construction, and daily life for the bonding, sealing, cushioning, and protection of materials.

[0003] Existing foam tapes also have the following problems: traditional tapes are often bulky, and when large quantities of tape are stored, they take up a lot of space, increasing storage costs. Moreover, in actual use, the adhesion effect of traditional tapes is not ideal. It is difficult to accurately fit the complex contours of the adhesive surface at the moment of application, and it is also difficult to insert into narrow work gaps, which can easily affect efficiency and work accuracy.

[0004] Therefore, there is an urgent need for a foam adhesive tape to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a foam tape to solve the problems of traditional tapes occupying a lot of space, having low efficiency and low work accuracy.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a foam tape, comprising:

[0007] The tape itself undergoes pre-compression treatment;

[0008] The tape body includes a release layer, an adhesive layer, and a foam layer connected in sequence;

[0009] The foam layer is pre-compressed to form a compressed shape.

[0010] As a preferred embodiment of foam tape, the foam layer is made of PU, and the PU foam layer is used to absorb impact, provide sound insulation and noise reduction, and provide sealing.

[0011] As a preferred embodiment of foam tape, the foam layer has oriented pores, the foam layer is easily compressible along the axial direction of the pores, and the foam layer is stable along the vertical axial direction of the pores.

[0012] As a preferred embodiment of foam tape, the adhesive layer is composed of solvent-based pressure-sensitive adhesive. The solvent-based pressure-sensitive adhesive layer is used to bond the tape body to the bonding surface and has a sealing effect, effectively blocking external substances.

[0013] As a preferred option for foam tape, the release layer is made of transparent PET release film. The transparent PET release film release layer is easy to tear, prevents external dust from adhering to the surface of the adhesive layer, and makes it easy to observe the adhesive layer to be bonded.

[0014] As a preferred embodiment of foam tape, the release layer is made of white release paper. The release layer of white release paper is easy to tear, prevents external dust from adhering to the surface of the adhesive layer, and is easy to identify.

[0015] As a preferred embodiment of foam tape, it also includes a roll, wherein the tape body is wound in an orderly manner around the outer circumference of the roll, and the roll is used to prevent the tape body from becoming tangled or knotted during storage.

[0016] As a preferred embodiment of foam tape, it further includes a clamping component disposed on the roll, and the clamping component elastically clamps the orderly wound tape body onto the roll.

[0017] As a preferred embodiment of foam tape, the compression assembly includes an elastic connector that is clamped onto the roll and the tape body, thereby maintaining the tape body in a pre-compressed state.

[0018] As a preferred embodiment of foam tape, the clamping assembly further includes a first clamp, a second clamp, and an elastic connector. The first clamp is disposed on the inner ring of the roll, the second clamp is disposed at the beginning of the tape body, and the elastic connector connects the first clamp and the second clamp. The width of the first clamp and the width of the second clamp are both greater than the diameter of the elastic connector.

[0019] The beneficial effects of this utility model are as follows: by setting a tape body with a release layer, an adhesive layer and a foam layer connected in sequence, and by pre-compressing the tape body, the initial roll is thin, and it expands after being unrolled. This avoids the need for expansion before compression and filling, which not only effectively saves storage space and facilitates large-scale storage in warehouses and other places, but also, due to its unique pre-compression and expansion characteristics, the tape can adhere more tightly to the adhesive surface during use, improving the adhesion strength. This further enhances the practicality and applicability of foam tape in different application scenarios, and also improves usage efficiency and operational accuracy. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0032] In one embodiment of this utility model, such as Figure 1-3 As shown, a foam tape is provided, comprising a tape body 1 having a release layer 11, an adhesive layer 12, and a foam layer 13 connected in sequence. The tape body 1 undergoes a pre-compression treatment; the tape body 1 includes a release layer 11, an adhesive layer 12, and a foam layer 13 connected in sequence; the foam layer 13 is pre-compressed to form a compressed shape.

[0033] The foam tape provided in this utility model, by setting a tape body 1 having a release layer 11, an adhesive layer 12 and a foam layer 13 connected in sequence, and by pre-compressing the tape body 1, makes the initial roll thin, and expands after being unrolled. This avoids the need for expansion before compression and filling, which not only effectively saves storage space and facilitates large-scale storage in warehouses and other places, but also, due to its unique pre-compression and expansion characteristics, allows the tape to adhere more tightly to the adhesive surface during use, improving the adhesion strength and further enhancing the practicality and applicability of the foam tape in different application scenarios.

[0034] Preferably, the foam layer 13 is made of PU, which is used to absorb impact, provide sound insulation and noise reduction, and seal. PU foam is chemically stable and has strong resistance to high and low temperatures, as well as acid, alkali, and salt corrosion. Whether under harsh outdoor conditions such as exposure to sun and rain, extreme heat and cold, or in special scenarios involving contact with chemical reagents, it is not prone to aging, deformation, or decomposition, maintaining good performance and ensuring long-term reliable use. This reduces the manpower and material costs associated with frequent material replacements and extends the lifespan of the foam tape.

[0035] Furthermore, the foam layer 13 has oriented pores, exhibiting compressibility and deformability along the axial direction of the pores and stability along the perpendicular axial direction of the pores. In automated pre-compression equipment, applying pressure along the axial direction of the foam pores allows the foam layer 13 to deform smoothly in this direction according to design requirements, achieving uniform and efficient pre-compression. The stability of the foam layer 13 along the perpendicular axial direction of the pores ensures that the foam adhesive expands only orderly along the axial direction of the pores.

[0036] Preferably, the adhesive layer 12 is composed of solvent-based pressure-sensitive adhesive. The solvent-based pressure-sensitive adhesive layer 12 is used to attach the tape body 1 to the bonding surface and has a sealing effect, effectively blocking external substances. Using tape containing solvent-based pressure-sensitive adhesive is very convenient. No complicated tools are required, and the application can be easily completed by hand. Construction workers can tear off the tape with one hand, accurately apply the decorative lines, and adjust the position easily. If the tape is applied in the wrong position, it can be peeled off and reapplied without leaving too much adhesive residue that could damage the surface of the object being applied, reducing rework trouble and speeding up the construction progress.

[0037] Preferably, the release layer 11 is made of transparent PET release film. The transparent PET release film release layer 11 is easy to tear, prevents external dust from adhering to the surface of the adhesive layer 12, and facilitates observation of the adhesive layer 12 to be bonded. The PET release film can be easily torn by hand without jamming or sticking, greatly improving work efficiency.

[0038] Preferably, the release layer 11 is made of white release paper. The white release paper release layer 11 is easy to tear, prevents external dust from adhering to the surface of the adhesive layer 12, and is easy to identify. The white release paper has a slightly different feel and is more frictional than some transparent materials, making it more stable when tearing by hand and avoiding improper tearing due to slipping, which would affect the use of the tape.

[0039] Preferably, the width of the tape body 1 is set to 8-45 mm. The narrow tape of 8-15 mm is suitable for narrow gaps between indoor tiles and small building components. It can be precisely inserted into the gap without wasting material. Moreover, the expansion of the foam layer 13 seals and waterproofs, preventing water from seeping into the cement layer and extending the life of the tiles. When there are parallel narrow gaps on the decorative tile mosaic wall, it is flexible in filling and easy to control the precision to ensure uniform gaps.

[0040] 30-45 mm wide tape is used for wide cement joints in large buildings and outdoor facilities. It can quickly cover the joints, reducing filling time. The foam layer 13 effectively fills the gaps, preventing debris and rainwater intrusion and protecting the building structure. For irregular wide joints such as cracks of varying widths on exterior walls, the tape body 1 can be flexibly filled by cutting and folding the tape to the appropriate width, which can enhance the building's airtightness.

[0041] When the width of the tape body 1 is 15 mm, it is convenient for workers to handle during construction. Compared with wider tapes, it is also easier to bend and adjust the direction. Narrower tapes require multiple fillings, but this can reduce the number of fillings and improve efficiency.

[0042] Preferably, the thickness of the tape body 1 varies from 5 mm to 30 mm. 10 mm can be pre-compressed to 5 mm, and 20 mm can be pre-compressed to 15 mm. The specific thickness can be set and produced according to the needs of the enterprise.

[0043] Preferably, the tape body 1 is 5-10 meters long, which meets the needs of common scenarios such as construction sites, daily homes, offices, and commercial packaging. It combines practicality, convenience, and economy, and is conducive to accurately targeting the target customer group.

[0044] like Figure 2-3 As shown, this type of foam tape also includes a roll 2. The tape body 1 is wound in an orderly manner around the outer circumference of the roll 2. The roll 2 is used to prevent the tape body 1 from becoming tangled or knotted during storage. As a stable support structure, the roll 2 can effectively limit the movement range of the tape, ensuring that it is always wound on the roll 2 in a predetermined manner, thereby avoiding the occurrence of tangling.

[0045] like Figure 4-6 As shown, this type of foam tape also includes a clamping component 3, which is disposed on a roll 2. The clamping component 3 elastically clamps the orderly wound tape body 1 onto the roll 2. By providing the clamping component 3, even if the foam tape is stored for a long time, the tape body 1 can always be stably held on the roll 2, maintaining a good initial state. It will not cause problems such as dust accumulation or loss of adhesion of the adhesive layer 12 due to accidental displacement during storage, thus extending the effective storage period of the tape and ensuring the performance of the tape in subsequent use. At the same time, it prevents the foam layer 13 from expanding, maintaining the pre-compressed state of the foam tape.

[0046] Specifically, the compression assembly 3 includes an elastic connector 33, which is clamped onto the roll 2 and the tape body 1, so that the tape body 1 is kept in a pre-compressed state.

[0047] Preferably, the elastic connector 33 can be made of a rubber ring, which is tied to the roll 2 and binds the tape body 1. After the tape body 1 is used, the rubber ring can elastically retract to bind the remaining tape body 1, maintaining the pre-compressed state of the foam tape.

[0048] Specifically, the clamping assembly 3 also includes a first clamping member 31, a second clamping member 32, and an elastic connector 33. The first clamping member 31 is disposed on the inner ring of the roll 2, the second clamping member 32 is disposed at the beginning of the tape body 1, and the elastic connector 33 connects the first clamping member 31 and the second clamping member 32. The width of the first clamping member 31 and the width of the second clamping member 32 are both greater than the diameter of the elastic connector 33. The first clamping member 31 and the second clamping member 32 can increase the area of ​​the tape body 1 being clamped, thereby improving the stability of clamping the tape body 1. When the tape body 1 is stretched out, the second clamping member 32 can cooperate with the elastic connector 33 to elastically retract and clamp the remaining tape body 1.

[0049] Furthermore, the first clamping element 31 partially encloses the roll 2, and the second clamping element 32 partially encloses the tape body 1, stabilizing the positions of the first clamping element 31 and the second clamping element 32. Since the surface of the release layer 11 is relatively slippery, if the remaining tape body 1 expands automatically, and the first clamping element 31 and the second clamping element 32 do not enclose the roll 2 and the tape body 1, they will continuously move in the direction of releasing the tape body 1 under the action of the expansion force, causing clamping failure. Preferably, anti-slip protrusions 4 can also be provided on the mating surfaces of the first clamping element 31 and the roll 2, and on the mating surfaces of the second clamping element 32 and the tape body 1. The anti-slip protrusions 4 can be integrally formed with the corresponding first clamping element 31 and the second clamping element 32, and the anti-slip protrusions 4, the first clamping element 31, and the second clamping element 32 can be made of plastic.

[0050] Furthermore, the first clamping element 31 is positioned partially around the roll 2, while the second clamping element 32 correspondingly partially covers the tape body 1. This arrangement stabilizes the positions of the first clamping element 31 and the second clamping element 32. It should be noted that, due to the relatively smooth surface of the release layer 11, when the remaining tape body 1 expands automatically, if the first clamping element 31 and the second clamping element 32 do not fully cover the roll 2 and the tape body 1, they are prone to slipping along the direction of tape body 1 release under the expansion force, resulting in clamping failure.

[0051] To avoid this situation, a preferred solution is to provide anti-slip protrusions 4 on the mating surfaces of the first clamping member 31 and the roll 2, and on the mating surfaces of the second clamping member 32 and the tape body 1. The anti-slip protrusions 4 can be manufactured integrally with the corresponding first clamping member 31 and second clamping member 32 using a molding process, and the anti-slip protrusions 4, the first clamping member 31, and the second clamping member 32 are all made of plastic to enhance the mating effect, increase the coefficient of friction, and effectively prevent clamping failure caused by displacement.

[0052] When the elastic connector 33 is a rubber ring, it can pass through the first clamp 31 and the second clamp 32, and a heat source can be used to heat the rubber ring to create dots, thus connecting the elastic connector 33 with the first clamp 31 and the second clamp 32. After the tape body 1 is used up, the elastic connector 33, the first clamp 31, and the second clamp 32 can be recycled.

[0053] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
