Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, and in particular to a polypropylene reinforced fiber anti-corrosion adhesive tape. Background Technology

[0002] Polypropylene reinforced fiber tape is a functional tape widely used in pipeline corrosion protection, electronic shielding, and industrial sealing. Traditional anti-corrosion tapes typically use polypropylene film as the base material, achieving adhesion and fixation to the object through adhesives. To improve the tape's anti-corrosion performance, an anti-corrosion layer is added to the polypropylene film to reduce corrosion.

[0003] However, existing polypropylene tapes have limited anti-corrosion properties. Conventional anti-corrosion layers provide static protection, and once scratches or damage occur, corrosive media can penetrate from the defects, causing the protection to fail and requiring frequent replacement. Furthermore, ordinary pressure-sensitive adhesives have limited initial tack and are prone to delamination under temperature changes or vibration environments. They also cannot adapt to uneven substrates, resulting in a short tape lifespan and affecting the tape's strong adhesion to objects. Utility Model Content

[0004] The purpose of this invention is to provide a polypropylene reinforced fiber anti-corrosion tape to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polypropylene reinforced fiber anti-corrosion tape, comprising:

[0006] Polypropylene film;

[0007] A graphene conductive mesh, wherein the graphene conductive mesh is embedded in the inner cavity of a polypropylene film;

[0008] A polyester fiber layer, wherein the polyester fiber layer is fixed to the outer wall of the polypropylene film;

[0009] A composite anti-corrosion coating is disposed on the inner wall of a polypropylene membrane;

[0010] A reinforcing fiber layer is disposed on the inner wall of the composite anti-corrosion coating;

[0011] An adhesive is applied to the inner wall and inner surface of the reinforcing fiber layer.

[0012] Preferably, the composite anti-corrosion coating comprises:

[0013] An anti-corrosion layer is fixed to the inner wall of the polypropylene membrane;

[0014] The recovery agent capsules, in an irregular oblique structure, are laid in the inner cavity of the anti-corrosion layer.

[0015] Preferably, the recovery agent capsule comprises:

[0016] The capsule shell and the restorative gel are used, wherein the restorative gel fills the inner cavity of the capsule shell, and the capsule shell is fixed in the inner cavity of the antiseptic layer in a long strip structure.

[0017] Preferably, the reinforcing fiber layer comprises:

[0018] A fiber mesh, wherein the fiber mesh is laid flat in a mesh pattern, and the adhesive is disposed in the inner cavity and inner wall surface of the fiber mesh;

[0019] A fiber substrate, which is fixed to the inner wall of the anti-corrosion layer;

[0020] Microsphere structure, wherein multiple microsphere structures are fixed on a fiber mesh.

[0021] Preferably, the fiber mesh is integrally formed and fixedly connected to the fiber substrate, and the microsphere structure is disposed in the inner cavity of the adhesive.

[0022] Preferably, the microsphere structure comprises:

[0023] A spherical membrane, the spherical membrane being fixed to the inner wall of a fiber mesh;

[0024] A tackifier, which fills the inner cavity of the spherical membrane.

[0025] The technical effects and advantages of this utility model are as follows:

[0026] This invention utilizes a combination of graphene conductive mesh, polyester fiber layer, composite anti-corrosion coating, and reinforcing fiber layer. The graphene conductive network is embedded within the polypropylene film, forming a continuous conductive path, eliminating static electricity hazards, and making it suitable for flammable and explosive environments. The self-healing composite anti-corrosion coating provides long-term protection for the tape. When the tape surface is slightly scratched or damaged, the capsule ruptures, releasing a repair agent. Under the influence of moisture in the air, this agent automatically fills the damaged areas of the polypropylene film on the tape, restoring the tape's anti-corrosion and sealing properties, reducing the impact of scratches on protection. Furthermore, the microsphere structure embedded in the fiber mesh enhances adhesion strength, fills micropores on the substrate surface, and is suitable for rough surfaces, improving the tape's adhesion to objects and extending its service life.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides, for example Figs. 1-3 The polypropylene reinforced fiber anti-corrosion tape shown includes a polypropylene film 1, a graphene conductive mesh 2, a polyester fiber layer 3, a composite anti-corrosion coating 4, a reinforcing fiber layer 5, and an adhesive 6. The graphene conductive mesh 2 is embedded in the inner cavity of the polypropylene film 1. By doping the conductive graphene conductive mesh 2 into the polypropylene film 1, a conductive network can be formed in the polypropylene film 1, giving the tape good conductivity. It is suitable for occasions requiring static discharge or grounding, effectively preventing static electricity from damaging electronic components and reducing safety hazards. The polyester fiber layer 3 is fixed to the outer wall of the polypropylene film 1. The polyester fiber layer 3 enhances the tensile strength of the tape. The composite anti-corrosion coating 4 is disposed on the inner wall of the polypropylene film 1, and the reinforcing fiber layer 5 is disposed on the inner wall of the composite anti-corrosion coating 4. The composite anti-corrosion coating 4 and the reinforcing fiber layer 5 increase the anti-corrosion performance and toughness of the tape. The adhesive 6 is coated on the inner wall and inner surface of the reinforcing fiber layer 5. The adhesive 6 is an environmentally friendly adhesive material, which facilitates the adhesion and fixation of the tape to objects.

[0033] The composite anti-corrosion coating 4 includes an anti-corrosion layer 41 and a restorative agent capsule 42. The anti-corrosion layer 41 is fixed to the inner wall of the polypropylene film 1 and can block the intrusion of external corrosive media. The anti-corrosion layer 41 is a fluoropolymer and can block the penetration of acid and alkali media. Multiple restorative agent capsules 42 are laid in an irregular oblique structure in the inner cavity of the anti-corrosion layer 41. The restorative agent capsule 42 includes a capsule shell and a restorative agent gel. The restorative agent gel fills the inner cavity of the capsule shell. The capsule shell is a long strip structure and fixed in the inner cavity of the anti-corrosion layer 41. The restorative agent capsule 42 is a silane-modified repair gel. After scratching, the capsule breaks and the gel solidifies when exposed to moisture. When the tape surface is slightly scratched or damaged, the capsule shell breaks and the repair agent flows out. Under the action of moisture in the air, it automatically fills the damaged part of the polypropylene film 1 on the tape, restores the anti-corrosion and sealing performance of the tape, improves the self-repair function of the tape, can extend the service life of the tape, and reduce the frequent replacement and maintenance work due to tape damage.

[0034] In addition, the reinforcing fiber layer 5 includes a fiber mesh 51, a fiber underlayer 52, and microsphere structures 53. The fiber mesh 51 is laid out in a grid pattern. The adhesive 6 is disposed in the inner cavity of the fiber mesh 51 and on the inner wall surface of the fiber mesh 51. The fiber underlayer 52 is fixed to the inner wall of the anti-corrosion layer 41. The fiber mesh 51 and the fiber underlayer 52 are integrally formed and fixedly connected, which makes it easy for the adhesive 6 to be locked in the inner cavity of the fiber mesh 51, improving the stability of the position of the adhesive 6. The combination of the polyester fiber layer 3 and the fiber mesh 51 can doubly improve the bidirectional tensile strength of the tape, resulting in higher puncture resistance, less tearing during construction, and suitability for mechanical winding, thus improving the tape's adhesion performance. This makes the tape suitable for use in different fields such as pipeline anti-corrosion, electronic shielding, and industrial sealing, improving the functionality of the tape. Multiple microsphere structures 53 are fixed on the fiber mesh 51, which improves the adhesive performance of the tape.

[0035] Microsphere structure 53 is disposed in the inner cavity of adhesive 6. Microsphere structure 53 includes spherical membrane 531 and tackifier 532. Spherical membrane 531 is fixed to the inner wall of fiber mesh 51. Spherical membrane 531 is a lightweight, easily compressible EVA film. Tackifier 532 fills the inner cavity of spherical membrane 531. Tackifier 532 is an acrylic copolymer that can fill the micropores on the surface of the substrate, increasing the bonding strength by 50% (up to 15 N / cm). It is suitable for rough surfaces. When the tape is applied to an object, pressing the tape not only makes the adhesive 6 adhere better to the object, but also breaks the spherical membrane 531, allowing the tackifier 532 to flow out, which facilitates the increase of the adhesion between the tape and the object, improves the strong adhesion of the tape to the object, and increases the service life of the tape.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
