Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber-based adhesives, specifically to a weather-resistant fiberglass tape. Background Technology
[0002] Existing binding and securing tapes are used for bundling and transporting heavy objects, and for securing them, such as steel pipe bundling and glass installation. Besides high tensile strength, these tapes also possess strong adhesion and leave no residue. However, most commercially available tapes are based on hot melt adhesive systems, which have some shortcomings, as follows:
[0003] 1. If the tape is left on the object for more than 3-5 days, there will be adhesive residue when it is removed, especially on smooth surfaces (such as stainless steel pipes), which will make cleaning inconvenient.
[0004] 2. The adhesion of adhesives based on hot melt adhesive systems is greatly affected by the ambient temperature. The adhesion of the tape deteriorates in low or high temperature environments, resulting in unreliable bonding or loose binding. The application temperature environment is limited to 10-30℃. Utility Model Content
[0005] The purpose of this invention is to solve the problem that existing binding and fixing tapes are greatly affected by the environment and cannot be firmly bound.
[0006] The technical solution adopted to solve the technical problem proposed by this utility model is as follows: The weather-resistant fiberglass tape of this utility model includes a release layer, a composite substrate layer and an adhesive layer. The release layer and the adhesive layer are respectively located on both sides of the composite substrate layer. The composite substrate layer includes a PET film layer, a composite adhesive and fiberglass gauze stacked in sequence. The release layer is coated on one side of the PET film layer, the composite adhesive layer is coated on the other side of the PET film layer, the fiberglass gauze is laminated on the composite adhesive layer, and the adhesive layer is coated on the fiberglass gauze.
[0007] The technical solutions that further define this utility model include:
[0008] The side of the PET film coated with the release layer has a corona treatment surface.
[0009] The fiberglass yarn has a weaving density of 35 mesh.
[0010] The thickness of the fiberglass gauze is 90-110 μm.
[0011] The composite rubber is made from natural rubber.
[0012] The thickness of the PET film is 25-75 μm.
[0013] The thickness of the composite adhesive layer is 16-22 μm.
[0014] The adhesive layer has a thickness of 26-33 μm.
[0015] The adhesive layer is made of toluene, rubber, naphthenic oil, antioxidant, resin and synthetic rubber.
[0016] The beneficial effects of this utility model through the above technical solution are as follows: The weather-resistant fiberglass tape of this utility model includes a release layer, a composite substrate layer, and an adhesive layer. The release layer and the adhesive layer are located on both sides of the composite substrate layer. The composite substrate layer includes a PET film layer, a composite adhesive, and fiberglass gauze stacked in sequence. The release layer is coated on one side of the PET film layer, and the composite adhesive layer is coated on the other side of the PET film layer. The fiberglass gauze is laminated on the composite adhesive layer, and the adhesive layer is coated on the fiberglass gauze. It has strong tensile strength, is less affected by the environment, is not easily deformed, and is firmly bound. At the same time, it also has good adhesion, and it is not easy to leave adhesive residue when removed and the adhesion is firm. Attached Figure Description
[0017] Figure 1 This is a structural schematic diagram of a weather-resistant fiberglass tape according to the present invention. Detailed Implementation
[0018] The structure of this utility model will be further described below with reference to the accompanying drawings.
[0019] Reference Figure 1 A weather-resistant fiberglass tape includes a release layer 1, a composite substrate layer 2, and an adhesive layer 3. The release layer and adhesive layer are located on opposite sides of the composite substrate layer. The composite substrate layer 2 includes a PET film layer 21, a composite adhesive 22, and fiberglass gauze 23 stacked sequentially. The release layer is coated on one side of the PET film layer, the composite adhesive layer is coated on the other side of the PET film layer, the fiberglass gauze is laminated on the composite adhesive layer, and the adhesive layer is coated on the fiberglass gauze. In this embodiment, the side of the PET film layer coated with the release layer has a corona-electrode surface. Coating the release layer on the corona-electrode surface results in a stronger bond. The thickness of the PET film layer is 45 μm. In specific implementations, the thickness of the PET film layer can be 25-75 μm. In this embodiment, the fiberglass gauze has a weave density of 35 mesh and a thickness of 90-110 μm. This thickness of fiberglass gauze gives the tape excellent tensile strength and makes it less prone to deformation. In this embodiment, the composite adhesive is made from natural rubber. The thickness of the composite adhesive layer is 16-22 μm. This gives the tape a certain tensile strength and makes it less prone to deformation. In this embodiment, the adhesive layer thickness is 26-33 μm. The adhesive layer is made of toluene, rubber, naphthenic oil, antioxidant, resin, and synthetic rubber. The viscosity of the adhesive layer can reach 35,000-80,000 cps. The winding tension is controlled at 30-40 kgf. The weather-resistant fiberglass tape of this invention has strong tensile strength and good adhesion, leaving little adhesive residue upon removal and providing a firm bond.
