Description

Technical Field

[0001] The utility model relates to the field of aluminum foil tapes, in particular to an aluminum foil tape without lining paper coating. Background Art

[0002] Linerless aluminum foil tape is a special type of tape. Unlike traditional aluminum foil tape, linerless aluminum foil tape does not have a middle liner layer, which makes the tape lighter and easier to use. Because linerless aluminum foil tape has waterproof and flame retardant properties, it is often used in food packaging to ensure food safety and hygiene. In pipeline anti-corrosion projects, linerless aluminum foil tape can be used for pipeline insulation and anti-corrosion treatment.

[0003] In actual use, the end of the tape is often tightly attached to the tape each time it is used, making it difficult to tear off easily. This tight adhesion not only increases the difficulty of use, but also the tape itself is easily torn and deformed when it is torn off with force, affecting the use effect and aesthetics of the tape. Utility Model Content

[0004] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] A linerless aluminum foil tape comprises an inner tube portion and a tape portion, wherein the tape portion is connected to the inner tube portion, and the tape portion comprises:

[0006] substrate layer;

[0007] an adhesive layer connected to one side of the substrate layer and used for adhering the tape to an object;

[0008] A protective layer, connected to the other side of the substrate layer, for providing protection for the tape;

[0009] The anti-adhesive member is connected to the side of the protective layer away from the substrate layer, and is used to reserve a gap between the adhesive layer and the protective layer when the tape is wound, so as to facilitate the removal of the tape when it is used.

[0010] The protective layer comprises:

[0011] The radiation protection layer is connected to the substrate layer.

[0012] The protective layer also includes:

[0013] A heat-insulating layer connected to the side of the radiation-proof layer away from the substrate layer and used to increase the heat-insulating property of the tape;

[0015] The enhancement layer comprises:

[0016] The fiber mesh layer is connected to the thermal insulation layer and is used to increase the mechanical strength of the tape.

[0017] The enhancement layer further comprises:

[0018] A first insulating film connected between the heat insulating layer and the fiber mesh layer to enhance the insulation of the tape;

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Reference Figure 1-Figure 5 A linerless aluminum foil tape comprises an inner tube portion 1 and a tape portion 2, wherein the tape portion 2 is connected to the inner tube portion 1, and the tape portion 2 comprises: a substrate layer 20, which serves as the basic structure of the tape and provides the main body support of the tape, and the substrate layer 20 is made of aluminum foil; an adhesive layer 21, which is connected to one side of the substrate layer 20 and is used to adhere the tape to an object, and the adhesive layer 21 has a strong adhesive force and can firmly adhere the tape to the surface of various objects to ensure that the tape will not fall off or shift during use, and the adhesive layer 21 is made of a rubber-based adhesive, and can also be made of an acrylic-based adhesive; a protective layer 22, which is connected to the other side of the substrate layer 20 and is used to provide protection for the tape, and the multi-layer structure is designed as follows: The tape provides comprehensive protection, not only can it resist external physical damage, but also can enhance the functionality of the tape, greatly improving the use range and durability of the tape; the anti-adhesive member 23 is connected to the side of the protective layer 22 away from the substrate layer 20, and is used to reserve a gap between the adhesive layer 21 and the protective layer 22 when the tape is wound, so that the tape can be easily peeled off when in use. The projection shape of the anti-adhesive member 23 is a long strip, and its long strip projection design prevents the adhesion between the adhesive layer 21 and the protective layer 22 when the tape is wound, and reserves a peeling opening for the tape, so that the tape can be easily peeled off when in use, thereby improving the user experience. The anti-adhesive member 23 is made of polytetrafluoroethylene film and can also be made of silicone oil coating.

[0037] Reference Figure 2 and Figure 3The protective layer 22 includes: an anti-radiation layer 222, which is connected to the substrate layer 20, effectively blocks and reduces the influence of electromagnetic radiation on the performance of the tape, protects the internal structure of the tape from external electromagnetic interference, and enhances the safety and stability of use. The anti-radiation layer 222 adopts a metal oxide coating; a thermal insulation layer 221, which is connected to the side of the anti-radiation layer 222 away from the substrate layer 20, and is used to increase the thermal insulation of the tape, significantly improving the thermal insulation performance of the tape, so that it can maintain good performance and service life in high or low temperature environments, and expanding the application scenarios of the tape. The thermal insulation layer 221 adopts bubble film and can also use ceramic fiber; a reinforcing layer 223, which is connected to the side of the thermal insulation layer 221 away from the anti-radiation layer 222, and further improves the overall performance and safety of use of the tape by increasing the mechanical strength and insulation of the tape.

[0038] Reference Figure 3-Figure 5 The reinforcing layer 223 includes: a fiber mesh layer 2231, connected to the insulation layer 221, for increasing the mechanical strength of the tape; a first insulating film 2232, connected between the insulation layer 221 and the fiber mesh layer 2231, for enhancing the insulation of the tape; a second insulating film 2233, connected to the fiber mesh layer 2231, and the anti-sticking member 23 is connected to the second insulating film 2233. The two layers of insulating film enhance the electrical insulation performance of the tape and improve the safety during use. The first insulating film 2232 and the second insulating film 2233 are both made of PVC film.

[0039] The fiber mesh layer 2231 is made of glass fiber mesh, and may also be made of nylon fiber mesh.

[0040] During use, an adhesive layer 21 is coated on one side of the aluminum foil substrate layer 20 to ensure that the adhesive layer 21 is uniform. On the other side of the substrate layer 20, an anti-radiation layer 222, a heat insulation layer 221, and a reinforcement layer 223 are sequentially stacked. During the stacking process, it is ensured that the layers are tightly combined without bubbles and gaps. An anti-sticking member 23 is connected to the outermost layer of the reinforcement layer 223, i.e., the second insulating film 2233. The anti-sticking member 23 covers the surface of the second insulating film 2233 and keeps it flat. The manufactured tape portion 2 is connected to the inner cylinder portion 1, and the tape is started to be wound. During the winding process, the anti-sticking member 23 acts to leave a gap between the adhesive layer 21 and the protective layer 22 to prevent adhesion. Each time the tape is lifted, the anti-sticking member 23 will leave a partial area of ​​the tape to facilitate the lifting of the tape.

[0041] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0042] The anti-sticking member 23 can reserve a gap between the adhesive layer 21 and the protective layer 22, avoiding close fitting of the ends of the tape, so that the user can easily peel off the tape when using it without tearing it laboriously, which greatly improves the convenience of use.

[0043] Since the tight fit at the end of the tape is eliminated, users do not need to apply excessive force when tearing the tape, reducing the risk of the tape itself being torn and deformed. This not only maintains the integrity of the tape, but also ensures the aesthetics of the tape during use.

[0044] The anti-radiation layer 222 can block electromagnetic radiation, the heat-insulating layer 221 can withstand high or low temperature environments, and the reinforcing layer 223 enhances the mechanical strength and insulation of the tape, so that the tape can maintain good performance in various environments and reduce safety risks during use.
