Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, in particular to a glass fiber cloth adhesive tape used for sealing aircraft cargo compartments. Background Art

[0002] Glass fiber cloth tape is made of a layer of pressure-sensitive adhesive coated on a glass fiber cloth substrate. It is specifically composed of glass fiber cloth with a thickness of 100-150μm and a pressure-sensitive adhesive with a thickness of 30-60μm. Due to the excellent strength and stiffness, heat resistance, insulation, and sound insulation of glass fiber cloth, it is often used for sewing and sealing panels and is a specialty tape.

[0003] Currently, fiberglass cloth tape is manufactured on the market by applying a release agent to the back of the fiberglass cloth and then rolling it up directly. However, applying acrylic pressure-sensitive adhesive directly to the fiberglass cloth results in incomplete contact with the cloth due to the uneven surface, resulting in low adhesion and a high risk of adhesive residue. The release agent layer on the back of the fiberglass cloth can create a slippery surface, which can cause moisture to form a damp layer on the surface, potentially affecting aircraft. Unwinding the tape for use as an aircraft sealing tape is difficult, making it inconvenient to apply. Furthermore, commercially available fiberglass cloth tapes all use conventional glue, which fails to meet aviation standards.

[0004] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a glass fiber cloth tape for sealing aircraft cargo holds, aiming to solve the problems of incomplete contact between the pressure-sensitive adhesive of the existing glass fiber tape and the glass fiber cloth, easy to have residual adhesive and difficult to unwind.

[0006] The technical solution of the utility model is as follows:

[0007] A glass fiber cloth tape for sealing an aircraft cargo hold comprises a wear-resistant coating, a glass fiber cloth, a primer layer, a flame-retardant pressure-sensitive adhesive layer, and a release film which are stacked in sequence from bottom to top.

[0009] The fiberglass cloth tape for sealing an aircraft cargo hold, wherein the material of the base coating layer is one of polysiloxane, silane coupling agent, and polyurethane resin.

[0010] The glass fiber cloth tape for sealing an aircraft cargo hold, wherein the thickness of the glass fiber cloth is 100 μm-150 μm.

[0011] In the glass fiber cloth tape for sealing an aircraft cargo hold, the thickness of the flame retardant pressure-sensitive adhesive layer is 30 μm-60 μm.

[0012] In the fiberglass cloth tape for sealing an aircraft cargo hold, the flame-retardant pressure-sensitive adhesive layer is made of one of acrylic pressure-sensitive adhesive, rubber pressure-sensitive adhesive, and silicone pressure-sensitive adhesive.

[0013] The glass fiber cloth tape for sealing an aircraft cargo hold, wherein the thickness of the wear-resistant coating is 10 μm-20 μm.

[0014] The fiberglass cloth tape for sealing an aircraft cargo hold, wherein the material of the wear-resistant coating is one of polyurethane resin, acrylic resin, and epoxy resin.

[0015] The glass fiber cloth tape for sealing an aircraft cargo hold, wherein the thickness of the release film is 30 μm-60 μm.

[0017] Beneficial Effects: The present invention provides a fiberglass cloth tape for aircraft cargo hold sealing, comprising a wear-resistant coating, fiberglass cloth, a primer, a flame-retardant pressure-sensitive adhesive layer, and a release film stacked sequentially from bottom to top. The primer layer is added between the fiberglass cloth and the flame-retardant pressure-sensitive adhesive layer to enhance adhesion between the flame-retardant pressure-sensitive adhesive layer and the fiberglass cloth, reducing debonding when replacing the fiberglass cloth. In addition, a release film is provided on the side of the flame retardant pressure-sensitive adhesive layer away from the primer coating, which can reduce the influence of water vapor infiltration and formation of a moisture layer due to the smooth surface of the glass fiber cloth.

[0023] like Figure 1 As shown, the utility model provides a glass fiber cloth tape for sealing an aircraft cargo hold, comprising a wear-resistant coating 10, a glass fiber cloth 20, a primer 30, a flame-retardant pressure-sensitive adhesive layer 40, and a release film 50 stacked in sequence from bottom to top.

[0024] In this embodiment, the primer layer is added between the glass fiber cloth and the flame retardant pressure-sensitive adhesive layer to increase the adhesion between the flame retardant pressure-sensitive adhesive layer and the glass fiber cloth, thereby reducing debonding when replacing the glass fiber cloth. Furthermore, a release film is provided on the side of the flame retardant pressure-sensitive adhesive layer facing away from the primer layer to reduce the effect of water vapor infiltration and formation of a damp layer due to the smooth surface of the glass fiber cloth. Furthermore, the release film can be flexibly sampled according to the size of the wallboard to be pasted, thereby reducing material loss and making it easier to unwind the glass fiber cloth tape. Furthermore, the flame retardant pressure-sensitive adhesive layer has excellent flame retardant properties, which can enhance the flame retardant effect of the glass fiber cloth tape. A wear-resistant coating is provided on the side of the glass fiber cloth facing away from the primer layer to effectively enhance the surface friction of the glass fiber cloth tape, provide a waterproof barrier effect, and extend the service life of the tape.

[0025] In some embodiments, the thickness of the primer layer is 3 μm-10 μm; for example, the thickness of the primer layer can be but is not limited to 3 μm, 3.5 μm, 4 μm, 4.5 μm, 5 μm, 5.5 μm, 6 μm, 6.5 μm, 7 μm, 7.5 μm, 8 μm, 8.5 μm, 9 μm, 9.5 μm, 10 μm, etc.

[0026] In a preferred embodiment, the thickness of the primer layer is 5 μm.

[0027] In some embodiments, the material of the primer layer is, but not limited to, one of polysiloxane, silane coupling agent, and polyurethane resin.

[0028] Specifically, the primer layer made of the above-mentioned material can increase the bonding strength between the flame-retardant pressure-sensitive adhesive layer 40 and the glass fiber cloth 20; and the thickness of the primer layer is controlled between 3μm-10μm, which can increase the bonding between the flame-retardant pressure-sensitive adhesive layer 40 and the glass fiber cloth 20. The primer layer with a thickness between 3μm-10μm formed by the above-mentioned material can effectively reduce the debonding phenomenon by increasing the bonding strength.

[0029] In some embodiments, the glass fiber cloth has a thickness of 100 μm-150 μm. For example, the thickness of the glass fiber cloth may be, but is not limited to, 100 μm, 102 μm, 104 μm, 110 μm, 115 μm, 118 μm, 120 μm, 125 μm, 130 μm, 132 μm, 137 μm, 139 μm, 140 μm, 145 μm, 150 μm, etc. Glass fiber cloth within this thickness range can control the overall thickness of the glass fiber cloth tape without affecting its performance, and also has excellent flame retardancy and fire resistance.

[0030] In a preferred embodiment, the glass fiber cloth has a thickness of 125 μm.

[0031] In some embodiments, the thickness of the flame retardant pressure-sensitive adhesive layer is 30 μm to 60 μm. For example, the thickness of the primer layer may be, but is not limited to, 30 μm, 32 μm, 35 μm, 40 μm, 42 μm, 45 μm, 46 μm, 48 μm, 50 μm, 51 μm, 53 μm, 55 μm, 57 μm, 59 μm, or 60 μm.

[0032] In a preferred embodiment, the thickness of the flame retardant pressure-sensitive adhesive layer is 40 μm.

[0033] In some embodiments, the flame retardant pressure-sensitive adhesive layer is made of one of acrylic pressure-sensitive adhesive, rubber pressure-sensitive adhesive, and silicone pressure-sensitive adhesive.

[0034] Specifically, the flame retardant pressure-sensitive adhesive layer formed by the above-mentioned material not only improves the flame retardant effect of the glass fiber cloth tape, but also does not significantly reduce the stickiness of the tape, and can meet the flame retardant requirements of airworthiness.

[0035] In some embodiments, the wear-resistant coating has a thickness of 10 μm to 20 μm. For example, the glass fiber cloth may have a thickness of, but is not limited to, 10 μm, 10.5 μm, 11 μm, 11.5 μm, 12 μm, 12.5 μm, 13 μm, 13.5 μm, 14 μm, 14.5 μm, 15 μm, 15.5 μm, 16 μm, 18 μm, or 20 μm. Wear-resistant coatings within this thickness range can effectively extend the service life of PVC tapes and prevent damage to the PVC surface due to long-term friction.

[0036] In a preferred embodiment, the wear-resistant coating has a thickness of 15 μm.

[0037] In some embodiments, the wear-resistant coating is made of one of polyurethane resin, acrylic resin, and epoxy resin. Using a wear-resistant coating made of the above materials can effectively improve the wear resistance of the fiberglass cloth tape, extend the service life of the PVC tape, and prevent the PVC surface from being damaged by long-term friction.

[0038] In some embodiments, the release film has a thickness of 30 μm to 60 μm. For example, the glass fiber cloth may have a thickness of, but is not limited to, 30 μm, 32 μm, 35 μm, 40 μm, 45 μm, 48 μm, 50 μm, 52 μm, 55 μm, 58 μm, or 60 μm. The release film protects the glass fiber cloth tape from contamination, allows for flexible sampling based on demand, and reduces tape loss during use.

[0039] In a preferred embodiment, the thickness of the release film is 40 μm.

[0040] In some embodiments, the release film is one of a polyethylene release film, a polyester release film, and a polypropylene release film.

[0041] In some embodiments, the release film is in a flat film shape or a convex shape. The convex-shaped release film can better reduce the unwinding force, while the flat film shape release film can reduce the volume of the glass fiber cloth tape when rolled, making it easier to store.

[0042] In summary, the present invention provides a fiberglass cloth tape for aircraft cargo hold sealing, comprising a wear-resistant coating, fiberglass cloth, a primer, a flame-retardant pressure-sensitive adhesive layer, and a release film stacked sequentially from bottom to top. The primer layer is added between the fiberglass cloth and the flame-retardant pressure-sensitive adhesive layer to enhance adhesion between the flame-retardant pressure-sensitive adhesive layer and the fiberglass cloth, reducing debonding when replacing the fiberglass cloth. In addition, a release film is provided on the side of the flame retardant pressure-sensitive adhesive layer away from the primer coating, which can reduce the influence of water vapor infiltration and formation of a moisture layer due to the smooth surface of the glass fiber cloth. At the same time, the release film can be flexibly sampled according to the size of the wall panel to be pasted according to actual needs, thereby reducing material loss and making it easier to unwind the glass fiber cloth tape. In addition, the flame retardant pressure-sensitive adhesive layer has excellent flame retardant properties, which can improve the flame retardant effect of the glass fiber cloth tape. A wear-resistant coating is provided on the side of the glass fiber cloth away from the primer coating, which can effectively improve the surface friction of the glass fiber cloth tape, and can have a waterproof barrier effect, thereby extending the service life of the tape.
