Abstract
Description
Technical Field
[0001] The present invention relates to a tape and its application, as well as a structure using the tape. Background Art
[0002] When using a tape to bond a transparent material (such as glass) to a substrate (such as a door frame, a window frame, especially a metal door frame, a metal window frame), existing such tapes include transparent acrylic tapes, acrylic foam tapes or liquid adhesives. However, such tapes are very likely to have bubbles during the bonding process, and the bubbles generated when the tape is bonded to the substrate will show through the transparent material, affecting the appearance.
[0003] To solve this problem, the prior art usually prints on the corresponding positions of the glass with respect to the bonding tape and the metal frame to cover the bubbles generated during bonding. As Figure 1 shown, a masking layer of the same color as the metal frame 300 is printed at the positions around the glass 200 corresponding to the tape 100 and the metal frame 300, so as to cover the bubbles generated when the tape 100 is bonded. However, the existing such technology has the following defects: during the installation of glass in some structures, for example, in the installation of building glass, display board glass, display cabinet glass, automotive glass, etc., the color of the frame as the substrate will vary due to the design of the corresponding structure, environmental requirements, etc. Therefore, it is necessary to print the glass according to the color of the metal frame, which not only increases the cost, but also requires frequent replacement of the glass as a fitting during operations such as structure debugging, thereby reducing the operability. Further, the transparency effect of the printed glass will be greatly reduced and cannot meet people's requirements for transparency. Summary of the Invention
[0004] In view of this, an object of the present invention is to provide a tape with low cost and that does not damage the aesthetic requirements due to bubbles during bonding.
[0005] According to one aspect of the present invention, a tape is provided.
[0006] According to another aspect of the present invention, an application of the above tape in glass installation is also provided.
[0007] According to still another aspect of the present invention, a structure is also provided, which is installed with glass, and the glass is installed in the structure by the tape of the present invention.
[0008] To solve the above technical problems, the present invention adopts the following technical solutions:
[0009] The tape according to the present invention includes:
[0010] A transparent acrylic polymer layer;
[0011] An opaque layer formed over the transparent acrylic polymer layer; and
[0012] A first adhesive layer formed over the opaque layer.
[0013] Wherein, the transparent acrylic polymer layer is a main component of the tape and has a certain thickness. For example, according to some embodiments of the present invention, the thickness of the transparent acrylic polymer layer is 250 - 3000 μm.
[0014] When the tape is bonded to a rigid object with an uneven surface such as a metal frame, bubbles will inevitably be generated. Although the formation of bubbles can be correspondingly reduced by improving the composition of the tape, etc., it is still difficult to meet the appearance requirements. For this reason, by providing an opaque layer, the bubbles generated at the interface between the tape and the metal frame can be well masked.
[0015] In addition, in order to endow it with adhesiveness or further enhance its adhesiveness, a first adhesive layer is formed over the opaque layer. According to some embodiments of the present invention, a second adhesive layer is also formed on the side of the transparent acrylic polymer layer opposite to the opaque layer.
[0016] According to some embodiments of the present invention, a release film layer is formed on one or both sides of the outermost side of the tape. Among them, the release film material can adopt the release film materials commonly used in the art, such as PE release film, PET release film, etc., and the detailed description thereof is omitted herein.
[0017] According to some embodiments of the present invention, the opaque layer may be an opaque plastic layer, and the opaque plastic layer is a single layer or a co-extruded multi-layer opaque plastic layer. The opaque plastic layer contains: a resin selected from polyethylene terephthalate, polypropylene, polyurethane, acrylic polymer or a mixture thereof; and opaque pigment particles. Here, those of ordinary skill in the art can understand that the opaque plastic layer itself can be a single layer or a co-extruded multi-layer.
[0018] According to some other embodiments of the present invention, the opaque layer is formed by coating a paint containing metal pigments on the transparent acrylic polymer layer. That is to say, the opaque layer is a coating layer of a paint containing metal pigments, which is formed by coating on the transparent acrylic polymer layer. Thus, the same paint as the metal paint used for the metal frame can be coated at the corresponding position in the tape by methods such as printing and spraying. This is not only simple in process, but also can achieve better matching with the metal frame and will not have an adverse impact on the process performance of the tape.
[0019] According to still further embodiments of the present invention, the opaque layer is a metal foil layer, a laminate of a metal foil and a plastic film, or a plastic film coated with a metal. Among them, the plastic film coated with a metal can be formed by coating a metal layer on the plastic film by methods such as electroplating, vapor deposition, ion plating, etc.
[0020] According to still other embodiments of the present invention, the opaque layer is formed of a fabric, and the mesh number of the fabric is 18 - 450.
[0021] According to other embodiments of the present invention, the opaque layer is formed of paper, and the thickness of the paper is 10 - 200 μm.
[0022] Among them, characters or patterns can also be formed on the opaque layer. For example, characters or patterns can be formed by printing.
[0023] According to some embodiments of the present invention, the first adhesive layer and the second adhesive layer are formed of a pressure - sensitive adhesive, and the pressure - sensitive adhesive is selected from solvent - type pressure - sensitive adhesives, water - based pressure - sensitive adhesives, ultraviolet - curable pressure - sensitive adhesives, extruded acrylic pressure - sensitive adhesives, rubber - type pressure - sensitive adhesives, electron - beam polymerizable pressure - sensitive adhesives, silicone pressure - sensitive adhesives, and mixtures thereof.
[0024] Furthermore, the thicknesses of the first adhesive layer and the second adhesive layer are independent of each other and are respectively 2 - 3000 μm. That is to say, the thicknesses of the first adhesive layer and the second adhesive layer can be the same or different, and each thickness is 2 - 3000 μm.
[0025] The tape according to still other embodiments of the present invention includes:
[0026] A first transparent acrylic polymer layer;
[0027] An opaque layer, which is formed on the first transparent acrylic polymer layer; and
[0028] A second transparent acrylic polymer layer, which is formed on the opaque layer.
[0029] That is to say, compared with the tape of the above - mentioned embodiments, the tape according to this embodiment has transparent acrylic polymer layers on both sides of the opaque layer.
[0030] According to some embodiments of the present invention, the thicknesses of the first transparent acrylic polymer layer and the second transparent acrylic polymer layer are independent of each other and are respectively 250 - 3000 μm. That is to say, the thicknesses of the first transparent acrylic polymer layer and the second transparent acrylic polymer layer can be the same or different, and each is 250 - 3000 μm.
[0031] Similarly, in order to improve the adhesiveness of the tape, according to some embodiments of the present invention, an adhesive layer is further formed on the outer side of at least one of the first transparent acrylic polymer layer and the second transparent acrylic polymer layer.
[0032] According to some embodiments of the present invention, a release film layer is formed on one or both sides of the outermost side of the tape.
[0033] According to some embodiments of the present invention, the opaque layer is an opaque plastic layer, the opaque plastic layer is a single layer or a co-extruded multi-layer opaque plastic layer, and the opaque plastic layer contains: a resin selected from polyethylene terephthalate, polypropylene, polyurethane, acrylic polymer or a mixture thereof; and opaque pigment particles.
[0034] According to some other embodiments of the present invention, the opaque layer is formed by coating a paint containing metal pigments on the transparent acrylic polymer layer.
[0035] According to still some other embodiments of the present invention, the opaque layer is a metal foil layer, a laminate of a metal foil and a plastic film, or a plastic film coated with metal.
[0036] According to other embodiments of the present invention, the opaque layer is formed of a fabric, and the mesh number of the fabric is 18 - 450.
[0037] According to other embodiments of the present invention, the opaque layer is formed of paper, and the thickness of the paper is 10 - 200 μm.
[0038] Similarly, characters or patterns may also be formed on the opaque layer. For example, characters or patterns can be formed by printing.
[0039] According to some embodiments of the present invention, the adhesive layer is formed of a pressure-sensitive adhesive selected from solvent-based pressure-sensitive adhesives, water-based pressure-sensitive adhesives, ultraviolet light-curing pressure-sensitive adhesives, extruded acrylic pressure-sensitive adhesives, rubber-based pressure-sensitive adhesives, electron beam polymerization pressure-sensitive adhesives, silicone pressure-sensitive adhesives and mixtures thereof. Further, according to some embodiments of the present invention, the thickness of the adhesive is 2 - 3000 μm.

Detailed implementation manners
[0053] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention fall within the scope of protection of the present invention.
[0054] The tape according to some embodiments of the present invention includes: a transparent acrylic polymer layer, an opaque layer, and a first adhesive layer. Further, as Figure 2 shown, the tape further includes a second adhesive layer formed on the other side of the transparent acrylic polymer layer.
[0055] In addition, the tape according to some other embodiments of the present invention includes: a first transparent acrylic polymer layer, an opaque layer formed on the first transparent acrylic polymer layer, and a second transparent acrylic polymer layer formed on the opaque layer.
[0056] Further, in order to improve the adhesiveness of the tape, an adhesive layer is formed on the outer side of one side of the first transparent acrylic polymer layer or the second transparent acrylic polymer layer.
[0057] In order to further improve the adhesiveness of the tape, adhesive layers are formed on the outer sides of both the first transparent acrylic polymer layer and the second transparent acrylic polymer layer.
[0058] In addition, in some embodiments of the present invention, a release film layer (not shown) may be formed on one or both sides of the outermost side of the tape. The release film layer plays a role in protecting and isolating the tape and can improve the release property of the tape.
[0059] Below, the specific compositions of each layer and the like will be described first.
[0060] Here, it should be noted that when it comes to a tape containing multiple layers of transparent acrylic polymer layers or multiple layers of adhesive layers, the composition and thickness of the multiple layers of transparent acrylic polymer layers are independent of each other. That is, their compositions can be the same or different, and their thicknesses can be the same or different. In other words, the composition, thickness, preparation method, source, etc. of each layer can be independent of each other and not affected by the other party. Of course, from the perspective of improving operability requirements, the multiple layers of transparent acrylic polymer layers can be formed using the same material. Similarly, the composition and thickness of the multiple layers of adhesive layers are independent of each other, that is, their compositions can be the same or different, and their thicknesses can be the same or different. In addition, in the present invention, when it comes to a fabric, the mesh count of the fabric refers to the mesh count (n / inch), that is, the number of filaments per inch.
[0061]
Transparent acrylic polymer layer
[0062] The transparent acrylic polymer layer can be an acrylic polymer layer.
[0063] Optionally, the transparent acrylic polymer layer is a solid layer made of an acrylic polymer. The transparent acrylic polymer layer can be commercially available, such as selected from the transparent ACX plus series of products provided by tesa Tape Technologies GmbH.
[0064] Of course, the present invention is not limited to using the above-mentioned tape, and the present invention is equally applicable to other acrylic polymers. The transparent acrylic polymer layer has adhesiveness. The tape of the embodiment of the present invention is a double-sided tape, that is, both sides of the tape of the embodiment of the present invention have adhesiveness.
[0065] Specifically, the thickness of the transparent acrylic polymer layer can be 250 - 3000 μm. A transparent acrylic polymer layer with a certain thickness can fully exert the adhesiveness of the tape and ensure the adhesion effect on the transparent material and the substrate.
[0066]
Opaque layer
[0067] The opaque layer can be a single layer or a co-extruded multilayer (co-extruded multilayer films) opaque plastic layer, and the opaque plastic layer contains a resin and opaque pigment particles. Among them, the resin can be selected from polyethylene terephthalate (PET), polypropylene (PP), polyurethane (PU), acrylic polymer or a mixture thereof. The opaque pigment particles impart various colors to polyethylene terephthalate (PET), polypropylene (PP), polyurethane (PU) or a mixture thereof, and the colors include white, black and other colors. When the opaque layer of the embodiment of the present invention is an opaque plastic layer, the thickness of the opaque layer is preferably 2 - 200 μm.
[0068] Optionally, the opaque layer is formed by coating a paint containing metallic pigments on the transparent acrylic polymer layer. Thus, by methods such as printing and spraying, at corresponding positions in the tape where metallic paints used for metal frames are coated, not only is the process simple, but better matching with the metal frame can be achieved, and it will not have an adverse impact on the process performance of the tape.
[0069] In addition, the opaque layer in the embodiments of the present invention can also directly select a metal foil layer, such as an aluminum foil layer, a copper foil layer, a zinc foil layer, a stainless steel foil layer, or a laminate of the above-mentioned metal foil and a plastic film, or a plastic film coated with metal. Among them, a metal layer can be coated on the plastic film by methods such as electroplating, evaporation plating, and ion plating. Specific electroplating, evaporation plating, ion plating and other methods are understandable to those skilled in the art, and their detailed descriptions are omitted here. When the opaque layer in the embodiments of the present invention is a metal foil layer, a laminate of a metal foil and a plastic film, or a plastic film coated with metal, the thickness of the opaque layer 12 is preferably 10 - 200 μm.
[0070] In addition, the opaque layer can also be formed by a fabric, and the mesh number of the fabric can be 18 - 450 mesh.
[0071] In addition, the opaque layer can also be formed by paper, and the thickness of the paper is 10 - 200 μm.
[0072] Among them, for purposes such as appearance requirements, commercial promotion, and safety warnings, words or patterns can also be formed on the opaque layer by printing.
[0073] The opaque layer in the embodiments of the present invention is to provide a color for shielding bubbles, and its color can be observed through the transparent acrylic polymer layer. The color of the opaque layer can be selected from various colors such as white, black, gray, blue, and silver-white. Specifically, it can be determined according to the environment in which it is used. The selection of other properties of the opaque layer, such as optical properties and mechanical properties, can also be diverse. The selection of other properties of the opaque layer does not limit the present invention.
[0074]
Adhesive layer
[0075] The adhesive layer can be formed by a pressure-sensitive adhesive, and the pressure-sensitive adhesive can be selected from solvent-based pressure-sensitive adhesives, water-based pressure-sensitive adhesives, ultraviolet light-curing pressure-sensitive adhesives, extruded acrylic pressure-sensitive adhesives, rubber-based pressure-sensitive adhesives, electron beam polymerization pressure-sensitive adhesives, silicone pressure-sensitive adhesives, and mixtures thereof.
[0076] Furthermore, the thickness of the adhesive layer can be 2 - 3000 μm.
[0077] In addition, in the tape according to the embodiment of the present invention, in order not to affect the transparency of the transparent acrylic polymer layer, the adhesive layer preferably uses a transparent or semi-transparent adhesive.
[0078] Hereinafter, the tape of the present invention will be described by way of specific examples. It should be understood that the present invention is not limited to the following specific examples.
[0079] Example 1
[0080] As Figure 2 shown, the tape 10 according to this embodiment includes a transparent acrylic polymer layer 11, an opaque layer 12, and a first adhesive layer 13. The opaque layer 12 is formed on the transparent acrylic polymer layer 11, and the first adhesive layer 13 is formed on the opaque layer 12. That is to say, the opaque layer 12 is located between the transparent acrylic polymer layer 11 and the first adhesive layer 13.
[0081] Among them, the transparent acrylic polymer layer 11 uses the transparent ACX plus provided by tesa Tape Technology Co., Ltd. (thickness is 500 μm, visually transparent); the opaque layer 12 is a laminate formed by laminating aluminum foil and PET plastic (total thickness is 40 μm, the PET side shows a matte silver-white color, and the aluminum foil side shows a bright silver-white color). The first adhesive layer 13 is a pure acrylic pressure-sensitive adhesive, with a thickness of 50 μm and a colorless and transparent color.
[0082] The tape 10 of the embodiment of the present invention can be prepared as follows: The transparent acrylic polymer layer 11, the opaque layer 12, and the first adhesive layer 13 are sequentially laminated by providing appropriate pressure through a laminating device, for example, the tape 10 of Example 1 is formed by roll pressing. The opaque layer can be surface-treated before lamination. The specific process is, for example: in an air or nitrogen atmosphere, the opaque layer 12 is corona-treated until its surface energy is at least 54 dynes, and then it is laminated on the transparent acrylic polymer layer 11, and then the first adhesive layer 13 is laminated on it, and then laminated under appropriate pressure.
[0083]
Appearance Performance Evaluation
[0084] Test tape: The tape of Example 1
[0085] In addition, for comparison, a tape without the opaque layer 12 was used at the same time as Comparative Example 1. The tape of this Comparative Example 1 has the same layer structure, composition, and thickness as those in Example 1 except that it does not contain the opaque layer 12.
[0086] Test method: Use the adhesive tape of Example 1 and the adhesive tape of Comparative Example 1 to bond transparent glass to an aluminum substrate, respectively, to obtain Sample A and Sample B. Then place Sample A and Sample B in a climate test chamber and perform 20 cycles according to the test standard PV1200 of the German Volkswagen Group. After the 20 cycles, place Samples A and B at room temperature (23°C) and relative humidity of 50% for 24 hours and observe their appearance.
[0087] The test results are as follows Figure 3 As shown, sample A, i.e., the sample using the tape of Example 1, does not show any bubbles from the glass side, see Figure 3 (A); while sample B, i.e. the sample using the tape of Comparative Example 1, has more bubbles seen from the glass side, see Figure 3 (B).
[0088] That is to say, when the tape 10 of the embodiment of the present invention is used to bond a transparent material such as glass to a substrate such as a metal frame, even if bubbles are generated when the adhesive layer 13 is pressed onto the metal frame due to the slope, roughness, etc. of the metal frame surface, the bubbles can be effectively shielded by the opaque layer 12, thereby ensuring the appearance effect after installation.
[0089] Example 2
[0090] According to this embodiment, Figure 4 As shown, the adhesive tape 20 of this embodiment includes, from bottom to top, a first adhesive layer 21 , a transparent acrylic polymer layer 22 , an opaque layer 23 , and a second adhesive layer 24 .
[0091] The first adhesive layer 21 and the second adhesive layer 24 are formed of the same material as the first adhesive layer 13 in the first embodiment.
[0092] The transparent acrylic polymer layer 22 and the transparent acrylic polymer layer 11 in the first embodiment are made of the same material.
[0093] The opaque layer 23 is a laminate formed by laminating aluminum foil and PET plastic (with a total thickness of 40 μm, the PET side appears matte silver-white, and the aluminum foil side appears bright silver-white).
[0094] Apart from this, the components of other layers are the same as those of the corresponding layers in Example 1, and their description is omitted here.

The adhesive tape of Comparative Example 2 has the same layer structure, composition, and thickness as those of Example 1 except that the adhesive tape does not contain the opaque layer 23 .
[0098] Test method: Use the adhesive tape of Example 2 and the adhesive tape of Comparative Example 2 to bond transparent glass to an aluminum substrate, respectively, to obtain Sample C and Sample D. Then place Sample C and Sample D in a climate environment test box and perform 20 cycles according to the conditions of the German Volkswagen Group test standard PV1200. After the 20 cycles, place Samples C and D at room temperature (23°C) and relative humidity of 50% for 24 hours and observe their appearance.
[0099] The test results are as follows Figure 5 As shown, sample C, i.e., the sample using the tape of Example 2, does not show any bubbles from the glass side, see Figure 5 (A); while sample D, i.e. the sample using the tape of Comparative Example 2, has more bubbles seen from the glass side, see Figure 5 (B).
[0100] Example 3
[0101] like Figure 6 As shown, the adhesive tape 30 according to the embodiment of the present invention comprises, from top to bottom, a first transparent acrylic polymer layer 31 , an opaque layer 32 , and a second transparent acrylic polymer layer 33 .
[0102] Specifically, the opaque layer 32 is formed between the first transparent acrylic polymer layer 31 and the second transparent acrylic polymer layer 33 .
[0103] In this embodiment, the first transparent acrylic polymer layer 31 and the second transparent acrylic polymer layer 33 are solid layers made of acrylic polymer, specifically, a highly transparent acrylic polymer selected from tesa Tape Technology Co., Ltd. ACX plus .
[0104] The opaque layer 32 is a double-layer PET composite film, with a printed color layer in the middle of the double-layer PET film (for example, an orange layer in this embodiment, with a total thickness of 34 μm and PET film on both sides).
[0105] Apart from this, the components of other layers are the same as those of the corresponding layers in Example 1, and their detailed description is omitted here.
[0106]
Appearance performance evaluation
[0107] Test tape: Tape 30 of Example 3
[0108] Test method: Use the tape 30 of Example 3 to bond a piece of transparent glass to another piece of transparent glass, and then place it in a climatic chamber and cycle 20 times according to the test standard PV1200 of Volkswagen Group Germany. After 20 cycles, place it at room temperature (23 °C) and relative humidity of 50% for 24 hours and then observe its appearance.
[0109] The test results are as Figure 7 shown, and no bubbles can be seen from one side of the other piece of glass.
[0110] Example 4
[0111] As Figure 8 shown, the tape 40 according to the embodiment of the present invention, from top to bottom in sequence is: a first transparent acrylic polymer layer 41, an opaque layer 42, a second transparent acrylic polymer layer 43, and an adhesive layer 44.
[0112] Among them, the opaque layer is formed of a white paper substrate with a thickness of 120 μm.
[0113] In addition, the materials of the first transparent acrylic polymer layer 41 and the second transparent acrylic polymer layer 43 are the same, and are the same as the materials of the corresponding layers in Example 1. In addition, the composition of the adhesive layer 44 is the same as the materials of the corresponding layers in Example 1, and its detailed description is omitted here.
[0114] Example 5
[0115] As Figure 9 shown, the tape 50 according to the embodiment of the present invention, from top to bottom in sequence is: an adhesive layer 51, a first transparent acrylic polymer layer 52, an opaque layer 53, a second transparent acrylic polymer layer 54, and an adhesive layer 51.
[0116] For each layer, the same materials as the corresponding layers in Example 4 are respectively used, and their detailed descriptions are omitted here. The tape according to the embodiment of the present invention can be used for the installation of building glass, including the installation of outdoor and indoor glass. For example, the installation of window glass and door glass in houses such as shopping malls and residences. By bonding the glass and the door frame or window frame with the tape of the embodiment of the present invention, it can achieve shielding the bubbles generated during bonding of the tape, improving the appearance effect of the transparent glass installed on the door frame or window frame, and can also select an opaque layer with a color matching the different substrates, thereby avoiding the use of printed glass, which is beneficial to reducing production costs and ensuring the transparent effect of the glass.
[0117] The adhesive tape according to an embodiment of the present invention can also be used for the installation of glass in display cabinets, display boards, etc. By bonding the glass and the frame of the display cabinet with the adhesive tape according to an embodiment of the present invention, it is possible to shield the bubbles generated during bonding of the adhesive tape, improve the appearance effect of the transparent glass installed on the frame, and select an opaque layer that matches the color of different substrates, thereby avoiding the use of printed glass, which is beneficial to reducing production costs and ensuring the transparent effect of the glass. In addition, in combination with the requirements of advertising and safety warnings of the display cabinet, words or patterns can be printed on the opaque layer to further improve the display effect and visibility.
[0118] The adhesive tape according to an embodiment of the present invention can be used for installing automotive glass, such as window glass or door glass.

Since the adhesive tape according to an embodiment of the present invention has the above technical effects, the vehicle according to an embodiment of the present invention also has corresponding technical effects, that is, by providing an opaque layer in the adhesive tape, it is possible to shield the bubbles generated during bonding of the adhesive tape, improve the appearance effect of the transparent glass installed on the substrate, and also be able to select an opaque layer that matches the color of different substrates, thereby avoiding the use of printed glass, which is beneficial to reducing production costs and ensuring the transparent effect of the glass. The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
