Description

Technical Field

[0001] The present application relates to the technical field of aluminum foil glass fiber tape processing, and more specifically, to an aluminum foil glass fiber tape and a preparation method thereof. Background Art

[0002] The automotive wiring harness is the main route connecting the various parts of the vehicle's electrical system, and its quality directly affects the quality and performance of the vehicle. Aluminum foil fiberglass tape has good insulation, anti-interference and shielding properties. At the same time, aluminum foil fiberglass tape can work stably for a long time in a high temperature environment. Its maximum tolerance temperature can reach 150°C or even higher, which enables it to meet the use requirements in high temperature environments such as the engine compartment of the car. Aluminum foil fiberglass tape can effectively isolate the influence of high temperature environment on the wiring harness and protect the wiring harness from high temperature damage. At the same time, aluminum foil fiberglass tape as a wrapping material can effectively improve the insulation performance of the wiring harness and prevent current leakage and short circuit. It effectively shields external electromagnetic interference, protects the signal transmission in the wiring harness from interference, and ensures the stable operation of the automotive electrical system.

[0003] However, during use, the aluminum foil fiberglass tape is not tearable, which greatly increases the difficulty and complexity of the installation and maintenance process. In order to improve the tearability of the aluminum foil fiberglass tape, the strength of the aluminum foil fiberglass tape will be reduced, making the aluminum foil fiberglass tape extremely easy to tear. However, the reduction in the strength of the aluminum foil fiberglass tape will cause the tape to be easily damaged when subjected to external forces, which will seriously affect its actual application effect and durability in wire harness protection. Therefore, while pursuing the tearability of the aluminum foil fiberglass tape, how to take into account and maintain its necessary physical strength and comprehensive performance has become a key issue that needs to be urgently solved in the current field of material research and development and technology improvement. Summary of the invention

[0004] In order to improve the tearability and strength of aluminum foil glass fiber tape, the present application provides an aluminum foil glass fiber tape and a preparation method thereof.

[0005] In the first aspect, the present application provides an aluminum foil glass fiber tape, which adopts the following technical solution: An aluminum foil glass fiber tape comprises an aluminum foil layer, a polyurethane adhesive layer, a tearable glass fiber layer and a silicone layer in sequence, wherein the polyurethane adhesive layer is prepared from the following raw materials in percentage by weight: Polyurethane resin 40-50% Acrylic modified alkyd resin 5-10% Tackifier 10-15% Enhancer 8-12% Adhesive 2-4% Curing agent 1-2% The remaining amount is diluent; The reinforcing agent consists of nano solid filler and cellulose nano fiber.

[0006] By adopting the above technical solution, by introducing a tearable glass fiber layer and optimizing the formula of the polyurethane adhesive layer, the aluminum foil glass fiber tape is easier to tear off during installation and maintenance, reducing the difficulty and complexity of operation. At the same time, the addition of acrylic modified alkyd resin and reinforcing agent and other raw materials to the polyurethane adhesive layer significantly improves the physical strength of the tape. Even when the tape is subjected to external force, it is not easy to be damaged, thus ensuring its practical application effect and durable life in wire harness protection.

[0007] The polyurethane layer uses polyurethane as a base material to provide basic bonding and strength properties; the flexibility of the tape is improved by introducing acrylic modified alkyd resin, making it easier to tear off while maintaining strength; the tackifier increases the viscosity of the polyurethane adhesive layer to ensure that the aluminum foil layer and the tearable fiberglass cloth layer can be firmly adhered together. The adhesive improves the adhesion between the fiberglass cloth layer and the aluminum foil layer and the fiberglass layer, ensuring a tight bond between the layers of the tape, which helps to improve the overall stability and durability of the tape and prevent delamination or shedding during use. The diluent adjusts the viscosity of the adhesive layer for easy processing and application.

[0008] The reinforcing agent is composed of nano solid fillers and cellulose nanofibers. The nano solid fillers, with their tiny particle size and high specific surface area, effectively improve the strength and hardness of the adhesive layer and enhance the tape's ability to resist external damage. The cellulose nanofibers, with their excellent flexibility and dispersibility, improve the toughness and tear resistance of the adhesive layer, making the tape have good tearability while maintaining high strength. The reinforcing agent content is between 8% and 12%, which effectively balances the tearability and strength of the tape.

[0009] Preferably, the weight ratio of the nano solid filler to the cellulose nanofiber is 5:(8-12).

[0010] By adopting the above technical solution, the dosage of nano solid filler and cellulose nanofiber is optimized, and the physical strength of the adhesive layer is further improved, making the tape tougher and less prone to damage when subjected to external forces, while maintaining good tearability, reducing the operational difficulty during installation and maintenance.

[0011] Preferably, the nano solid filler is a modified nano solid filler, which is prepared by the following method: 1) placing a nano solid filler in an ethanol solution, adding a silane coupling agent, stirring, filtering, and collecting a filter residue to obtain a functionalized nano solid filler; 2) Adding functionalized nano solid filler, alkylene diacrylate, methyl acrylate, azobisisobutyronitrile and benzene into a reactor, raising the temperature of the reactor to 65-75° C., reflux the system, and heat-retaining the reaction for 4-5 hours, and post-treating to obtain modified nano silica.

[0012] By adopting the above technical solution, the dispersion of nano solid fillers in polyurethane resin is significantly improved, reducing the occurrence of agglomeration. The uniform dispersion enables the fillers to more effectively enhance the mechanical properties of the adhesive layer, making the aluminum foil glass fiber tape have higher strength and longer service life while maintaining tearability.

[0013] By treating the nano solid filler with a silane coupling agent to functionalize its surface, the compatibility and interfacial bonding between the filler and the polyurethane resin are enhanced, which helps to improve the overall strength and toughness of the polyurethane adhesive layer, making the tape more resistant to breakage when subjected to force, thereby improving its durability. Secondly, the alkylene diacrylate and methyl acrylate monomers added during the modification process react chemically with the functionalized nano solid filler, allowing the modified nano solid filler to better combine with the polyurethane resin to form a stable composite material, which helps to improve the overall stability and reliability of the tape, making the aluminum foil fiberglass tape tearable while also having good strength during use.

[0014] Preferably, the weight parts of the raw materials used to prepare the modified nano solid filler are as follows: Nano solid filler 12-14 parts Silane coupling agent 1-2 parts Ethanol 10-12 parts 2-3 parts of alkylene diacrylate 1-2 parts of methyl acrylate 0.3-0.5 parts of azobisisobutyronitrile 12-15 parts of benzene.

[0015] By adopting the above technical solution and using the above specific weight portions of raw materials to prepare modified nano solid fillers, the performance of aluminum foil glass fiber tape is significantly improved. The modified nano solid fillers prepared by this formula can significantly improve the strength and toughness of aluminum foil glass fiber tape while maintaining its good tearability, making the tape less likely to break when subjected to external forces, thereby extending the service life in applications such as wire harness protection.

[0016] Preferably, the silane coupling agent includes at least one of γ-(methacryloyloxy)propyltrimethoxysilane, γ-glycidyloxypropyltrimethoxysilane, 3-(2,3-epoxypropyloxy)propyltrimethoxysilane and γ-mercaptopropyltriethoxysilane.

[0017] By adopting the above technical solution, a strong chemical bond can be formed with the nano solid filler, thereby enhancing the compatibility and interfacial bonding strength between the nano solid filler and polyurethane, which not only improves the mechanical properties of the polyurethane adhesive layer, but also makes the tape more resistant to damage when subjected to force, thereby extending its service life.

[0018] Preferably, the diluent includes at least one of dimethyl carbonate, propylene carbonate, ethyl acetate, acryloylmorpholine, tetrahydrofuran acrylate, isobornyl acrylate, lauric acid acrylate and 1,6-hexanediol diacrylate.

[0019] By using the above diluent, the viscosity of the polyurethane resin can be effectively reduced, its processing performance can be improved, and the adhesive layer can be more uniform and smooth during the coating process. At the same time, the above diluent also has a certain volatility and can gradually evaporate during the curing process to form a dense and uniform adhesive layer structure, thereby improving the strength and toughness of the tape.

[0020] Preferably, the adhesive is composed of epoxy phosphate and γ-aminopropyltriethoxysilane coupling agent in a weight ratio of (3-5):1.

[0021] By adopting the above technical solution, the type and amount of adhesive are optimized, the adhesion performance between the adhesive layer and the aluminum foil layer and the glass fiber layer is further enhanced, and the stability and mechanical properties of the aluminum foil and glass fiber tape are enhanced. The aluminum foil and glass fiber tape has higher strength and longer service life while maintaining excellent tearability, meeting the needs of a variety of complex application scenarios.

[0022] Preferably, the tackifier is composed of β-terpene resin and rosin resin in a weight ratio of 2:(4-6).

[0023] By adopting the above technical solution and optimizing the type and amount of tackifier, not only the adhesion of the adhesive layer is significantly enhanced, but also the aluminum foil layer and the tearable fiberglass cloth layer can be firmly adhered together and not easy to fall off. As a high-performance natural polysaccharide, β-terpene resin has excellent thickening and stabilizing properties, which helps to improve the uniformity and stability of the polyurethane adhesive layer; while rosin resin, with its unique chemical structure and bonding properties, enhances the interaction between the polyurethane adhesive layer and the aluminum foil layer and the tearable fiberglass cloth layer. Therefore, the application of this tackifier makes the aluminum foil fiberglass tape have a wider range of applicability and a longer service life while maintaining high strength and tearability.

[0024] Preferably, the curing agent is one of hydroquinone dihydroxyethyl ether, resorcinol bishydroxyethyl ether, p-hydroxyethyl bisphenol A, 3,5-dimethylthiotoluenediamine, 3,3'-dichloro-4,4'-diphenylmethanediamine or 3,5-diethyltoluenediamine.

[0025] By adopting the above technical solutions, the polyurethane adhesive layer can reach an ideal curing state in a short time. At the same time, they can also form a strong chemical bond with the polyurethane, enhance the cohesive strength and adhesion of the adhesive layer, and improve the overall strength and durability of the tape.

[0026] In a second aspect, the present application provides a method for preparing an aluminum foil glass fiber tape, using the following technical solution: A method for preparing an aluminum foil glass fiber tape comprises the following steps: S1. According to the weight percentage, the polyurethane resin, acrylic modified alkyd resin, tackifier, reinforcing agent and diluent are stirred, and then the adhesive and curing agent are added and stirred evenly to obtain a polyurethane adhesive; S2. Coat polyurethane glue on the surface of aluminum foil, then spread glass fiber cloth on the surface of polyurethane glue and solidify it. Finally, coat silicone on the side of glass fiber cloth away from polyurethane glue layer and solidify it to obtain aluminum foil glass fiber tape.

[0027] By adopting the above technical solution, a high-performance polyurethane adhesive layer is formed by combining polyurethane resin with acrylic modified alkyd resin, supplemented by tackifiers, reinforcing agents and diluents. This adhesive layer not only has excellent adhesion and can closely adhere to aluminum foil and fiberglass cloth, but also has good flexibility and weather resistance, ensuring that the tape can maintain stable performance in various complex environments.

[0028] In summary, this application has the following beneficial effects: 1. Improve tearability: The introduction of the tearable glass fiber layer makes the tape easier to operate during installation and maintenance, reducing the difficulty and complexity of operation.

[0029] 2. Maintain high strength: By optimizing the formula of the polyurethane adhesive layer and using nano-level reinforcing agents, the tape can maintain the necessary physical strength and comprehensive performance while maintaining high tearability and is not easily damaged by external forces.
