Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil tapes, in particular to a fiber mesh reinforced high-toughness flame-retardant aluminum foil tape. Background Art

[0002] Aluminum foil tape is a composite film used in packaging, printing, electronics, food and beverages, and other products. It offers moisture-proof, dust-proof, and shock-resistant properties. It uses polyethylene as its backing material and plastic-coated PET or release paper as its face material. A special surface treatment creates a high-gloss, smooth, mirror-like finish. Furthermore, aluminum foil tape utilizes high-quality pressure-sensitive adhesive, offering excellent adhesion, strong tack, and anti-aging properties.

[0003] With the development of modern industry and technology, especially in some special environments, such as high temperature and flammable occasions, higher requirements are placed on the toughness and flame retardant properties of aluminum foil tapes. It can be seen that most aluminum foil tapes often seem to be unable to cope with these challenges, and the shortcomings in toughness and flame retardant properties gradually become apparent, thereby reducing the safety of aluminum foil tape use.

[0004] In view of this, we propose a fiber mesh reinforced high-toughness flame-retardant aluminum foil tape. Utility Model Content

[0005] The purpose of the utility model is to solve the above shortcomings and provide a fiber-reinforced mesh and a flame-retardant coating, so that the aluminum foil adhesive has a high-toughness flame-retardant ability.

[0006] By introducing the fiber-reinforced mesh, the overall toughness and tear resistance of the aluminum foil tape are improved. At the same time, by setting the flame-retardant coating, the aluminum foil tape has stronger flame retardancy while maintaining excellent conductivity.

[0007] Therefore, the utility model provides a fiber mesh reinforced high-toughness flame-retardant aluminum foil tape, which includes an aluminum foil base layer, and fiber reinforcement meshes are provided on the upper and lower sides of the aluminum foil base layer, which can effectively enhance the overall toughness and tear resistance of the aluminum foil tape;

[0008] A flame retardant coating is provided on the outer side of the fiber reinforced mesh located on the lower side of the aluminum foil base layer. The flame retardant coating can quickly form a protective layer when the aluminum foil tape encounters a fire source to prevent the spread of flames.

[0009] As a further improvement of the present technical solution, the flame retardant coating comprises at least a flame retardant, an adhesive and a filler layer, wherein the flame retardant is composed of oxides, phosphates and chlorides, etc., the adhesive is an organic solvent-based adhesive, and the filler layer is an organic filler, which can increase the thickness and hardness of the coating.

[0010] As a further improvement of the present technical solution, the aluminum foil base layer is made of high-strength and high-toughness aluminum foil material, and a micro-concave-convex structure is formed on the surface of the aluminum foil base layer to increase the contact area with the fiber-reinforced mesh.

[0011] As a further improvement of the present technical solution, the fiber-reinforced mesh is woven from high-strength and high-toughness fibers to form a tight mesh structure.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The fiber mesh reinforced high-toughness flame-retardant aluminum foil tape improves the overall toughness and tear resistance of the aluminum foil tape by introducing a fiber reinforcement mesh. At the same time, the flame-retardant coating is provided to enable the aluminum foil tape to have stronger flame retardancy while maintaining excellent conductivity. This not only enables the aluminum foil tape to maintain stable performance in complex environments and extend its service life, but also improves the safety of the use of the aluminum foil tape, thereby improving the reliability of the use of the aluminum foil tape.

[0022] With the development of modern industry and technology, especially in some special environments, such as high temperature and flammable occasions, higher requirements are placed on the toughness and flame retardant properties of aluminum foil tapes. It can be seen that most aluminum foil tapes often seem to be unable to cope with these challenges, and the shortcomings in toughness and flame retardant properties gradually become apparent, thereby reducing the safety of aluminum foil tape use.

[0023] See also Figure 1-Figure 3The embodiment of the utility model shown in the figure includes an aluminum foil base layer 10, and a fiber reinforcement mesh 20 is provided on the upper and lower sides of the aluminum foil base layer 10, which can effectively enhance the overall toughness and tear resistance of the aluminum foil tape; a flame retardant coating 30 is provided on the outer side of the fiber reinforcement mesh 20 located on the lower side of the aluminum foil base layer 10. The flame retardant coating 30 can quickly form a protective layer when the aluminum foil tape encounters a fire source to prevent the spread of flames.

[0024] First, the specific structure of the flame retardant coating 30 is disclosed. The flame retardant coating 30 at least includes a flame retardant 31, an adhesive 32 and a filler layer 33. The flame retardant 31 is composed of oxides, phosphates and chlorides, etc. The adhesive 32 adopts an organic solvent-type adhesive 32, and the filler layer 33 adopts an organic filler, which can increase the thickness and hardness of the coating.

[0025] The improvements are as follows: oxides such as aluminum oxide, aluminum hydroxide and magnesium oxide in the flame retardant 31 are used to reduce the combustion temperature of the material through heat absorption and heat insulation, and phosphates and chlorides can generate compounds, such as phosphate glass and chloride salts, to suppress the spread of flames; and an adhesive 32 is used to firmly bond the flame retardant 31 and the filler layer 33 together, and the organic solvent-based adhesive 32 is mainly composed of an organic solvent and a resin, and while the organic filler increases the thickness and hardness of the coating, it improves the flame retardant properties of the flame retardant coating 30, thereby improving the safety of the use of the aluminum foil tape.

[0026] In order to improve the contact stability between the aluminum foil base layer 10 and the fiber reinforced mesh 20 , the aluminum foil base layer 10 is made of high-strength and high-toughness aluminum foil material, and a micro-concave-convex structure is formed on the surface of the aluminum foil base layer 10 to increase the contact area with the fiber reinforced mesh 20 .

[0027] The improvements are: the high-strength and high-toughness aluminum foil material ensures the basic conductivity and thermal insulation properties of the tape, and can also provide stable support for the entire aluminum foil tape; and the aluminum foil base layer 10 has excellent corrosion resistance and oxidation resistance, and can resist the impact of harsh environments on the performance of the aluminum foil tape, and through the tiny concave and convex structure, increases the contact area with the fiber reinforced mesh 20, improves the stability of the overall structure, thereby ensuring the stability and reliability of the aluminum foil tape during use.

[0028] Since the aluminum foil tape is easily torn and deformed, thus affecting its use effect, the fiber reinforced mesh 20 is woven with high-strength and high-toughness fibers to form a tight mesh structure.

[0029] The improvement lies in that the fiber reinforced mesh 20 is woven from fibers to form a tight mesh structure, which can effectively enhance the overall toughness and tear resistance of the aluminum foil tape. At the same time, it can also provide the aluminum foil tape with a certain elasticity, so that it can have a better buffering effect when facing external forces, increase the stability and reliability of the tape use, thereby effectively enhancing the overall toughness and tear resistance of the aluminum foil tape.

[0030] In summary, the working principle of this solution is as follows: first, a high-strength, high-toughness aluminum foil material is used to make an aluminum foil base layer 10, and then a fiber-reinforced mesh 20 is used to weave the two sides of the aluminum foil base layer 10 to form a tight mesh structure. Then, a flame-retardant coating 30 is used to firmly combine the fiber-reinforced mesh 20 and the aluminum foil base layer 10 to complete the production of the aluminum foil tape.
