Definitions
- the invention relates to a joining method according to the preamble of claim 1.
- a first profile has a recess or cutout into which a correspondingly shaped, second profile dips or engages.
- the two profiles thus together form a partial shell of a carrier.
- the support structure itself can be designed as an open or as a hollow profile and comprise both parts.
- the purpose of nesting is usually to stiffen or seal the entire structure.
- the profiles used for this purpose can be made, for example, from light metal continuous casting or be formed from sheet metal blanks.
- the profiles are shifted into one another such that the connecting surfaces move at least partially tangentially to one another.
- the connecting surfaces may be parts of the profile body or molded flanges whose essential task is the connection of the profiles.
- the profiles used in the nesting are usually welded together at the connecting surfaces. Especially the spot welding process is used.
- the profiles can also be soldered, crimped, clinched or riveted together. Combinations of the methods are also used.
- adhesive bonds are increasingly being used to join profiles.
- the adhesive bonds not only increase the rigidity of the connection, but above all, they are also suitable for joining different materials.
- adhesive beads are used for sealing, for thermal and electrical insulation, and for noise reduction. By the separation of z.
- As aluminum and steel in a joint connection is ensured with the help of the adhesive that there is no electrocorrosion.
- activatable structural adhesives are used as adhesives for the production of carrier structures. These adhesives are typically applied in the form of adhesive beads. During or after activation, the adhesives usually cure by a chemical reaction. Activation can be via heat, humidity, radiation, z. As UV radiation, oxygen exclusion or other known mechanisms.
- Adhesive tapes are also known which generally achieve suitable strengths for the production of carrier structures by means of a physical or chemical hardening process.
- the adhesive tapes can be adhesive or not sticky. As a rule, the adhesive tape has no additional carrier.
- Non-sticky adhesive tapes are usually first connected by heating with a first profile, and so a Vorverbund is produced. Since the adhesive tape is sufficiently viscous, the interleaving operation can be performed despite tangential movement without shifting the adhesive geometry. After joining, a further heating causes a flow of the adhesive onto the second profile and, if appropriate, a chemical hardening.
- the disadvantage here is the high cost of producing the pre-bond. With pressure sensitive adhesive tapes, the pre-bond can be easily prepared by self-adhesiveness.
- the adhesive tape adheres to the second profile, so that the joining process is hindered and the clean formation of the adhesive seam is disturbed.
- a chemical hardening is then usually initiated by further heating or access of atmospheric moisture.
- the cited lecture proposes the use of a hybrid adhesive tape with a pressure-sensitive and a non-adhesive side.
- a disadvantage of this embodiment is that the adhesive tape have a complex multilayer structure got to. Furthermore, the bond with the joining component with the non-adhesive side only comes about after heating the system. Before, the composite has no strength.
- the joining process should be carried out under at least partial tangential movement without substantial deformation of the adhesive tape geometry or displacement of the prefixed adhesive tape.
- the object is achieved in a first aspect by an initially mentioned method with the features of claim 1.
- two parts to be joined are glued together by an adhesive tape.
- a first side of the adhesive tape is glued to a first surface of a first joining part.
- a first activatable adhesive is arranged on the first side of the adhesive tape.
- a second activatable adhesive is arranged which is an activatable PSA.
- the first and second adhesives may be the same or different from each other.
- the first adhesive is also an activatable PSA.
- This "contacting" is done by a joining movement having a tangential and a vertical component with respect to the second side of the adhesive tape, wherein the ratio between tangential and vertical component, in particular with respect to at least a part of the second side of the adhesive tape, greater than 0.5, preferably greater than 1, particularly preferably greater than 4.
- the tangential component of the joining movement is already so great that significant adhesion of the second side of the PSA to the second joining part can occur
- the tangential component predominates, at a ratio of 4, the movement is so strongly determined by the tangential component that, for example, no pasty adhesives can be used (see Wieczorek supra), so that the method according to the invention is particularly can be used advantageously.
- the ratio of the two components to one another can become very large if the joining movement takes place almost tangentially to the second side of the adhesive tape. In extreme cases, the joining movement can also be completely tangential to the second side of the adhesive tape.
- the contact region between the second surface of the second adherend and the second side of the adhesive tape has a nonaqueous lubricant.
- the non-aqueous lubricant causes the tacky second side of the adhesive tape to not immediately adhere to the second surface upon first contact with the second surface of the second adherend but to slide along it until an end position of the first and second adherends relative to each other is achieved.
- the second side of the adhesive tape has a pressure-sensitive adhesive.
- the adhesive is layered or flat.
- the adhesive tape can consist of a single homogeneous adhesive, but it is also conceivable that the adhesive tape has a multilayer structure, in particular an inner carrier layer which is coated on both sides with an adhesive in each case.
- the adhesive tape has a single-layer structure and the adhesive tape consists of a single-layer, preferably activatable pressure-sensitive adhesive. As a result, the pre-bond can be easily manufactured and the tape is inexpensive and easy to produce.
- the thickness of the adhesive tape corresponds to the thickness customary for adhesive tapes, that is to say from about 1 ⁇ m to 5 mm.
- Preferred for structural bonding in the automotive sector is a thickness of 50 ⁇ to 5 mm, in particular from 150 ⁇ to 2 mm.
- a premature adhesion of the second adhesive tape side on the second joint part surface has a particularly disadvantageous, since then a position error of the bond is particularly large. Therefore, adhesive tapes in this thickness range are preferably used in the method according to the invention.
- the adhesive tape may have a single-layer or multi-layer structure.
- other layers as they are well known to those skilled in the field of adhesive tapes, may be present, for.
- the adhesive tape is usually provided as a section of a long adhesive tape.
- the tape can z. B. as a sheet or as a section of a roll or, conveniently, as a stamped product are provided.
- the adhesive tape may simply be continuous or holes or openings may also be provided in the adhesive tape.
- the adhesive tape may completely cover the area bounded by its outer circumference, or even if it has openings, it may also cover only parts of it or leave parts free.
- the adhesive tape is significantly larger in two dimensions than in a third dimension. However, it may well be formed in the first two dimensions about the same size and thus have a circular, square or other outer, planar shape.
- the second side is provided with an activatable pressure-sensitive adhesive.
- the first and the second side of the adhesive tape are provided with an activatable pressure-sensitive adhesive.
- the first and second sides may also have the same adhesive in specific embodiments.
- activatable PSAs it is possible in principle to use all customary, adhesively bonded PSA systems which have been activated.
- the activation is usually via an energy input, z. B. by actinic radiation or heat or mechanical energy, such as. As ultrasound or friction. But is also a chemical activation by z. As moisture or oxygen or its exclusion or by other chemical activators, such as. B. peroxides.
- Heat-activated adhesive PSAs can basically be classified into two categories: thermoplastic, heat-activated adhesive PSAs (adhesive adhesives) and reactive, heat-activated adhesive PSAs (reactive adhesives). This classification also contains those PSAs which can be assigned to both categories, namely reactive and at the same time thermoplastic, heat-activated adhesive adhesive compositions (reactive hot melt pressure sensitive adhesives). Reactive pressure-sensitive adhesives are preferred for the preparation of carrier structures of nested profiles.
- Thermoplastic pressure-sensitive adhesives are based on polymers which reversibly soften when heated and solidify again during cooling.

- Table 3 shows that the bond strength, through the use of the lubricant G1 for which the tests were carried out, is consistently lower after 24 hours or after one hour, but the decrease depends very much on which adhesive was used.
- the adhesives K1 and K4 absorb the oil comparatively quickly, so that after one hour of storage, the adhesive force is greater than 50% of the adhesive force after 24 hours of storage, while the adhesives K2 and K3 absorb the oil more slowly, so that the bond strength after one hour Storage not higher than 30% of the bond strength after 24 h storage.
- the adhesives K1 or K4 would preferably be selected for the first side 4 of an adhesive tape 3 for bonding two oiled sheets 1 and 6, while the adhesives K2 or K3 would be selected for the second side 7 of the adhesive tape 3.
- the shear strength achieved after activation is only slightly impaired by the lubricant, as is the case with the adhesives K1 and K4; in particular, the shear strength is reduced by not more than 15%, for K2, K3 and K4 even less than 10%.
- Essential is the assessment of the lubricity of the various lubricants G1 to G6, which were applied to the adhesives K1 to K4. The following experimental setup was chosen:
- a glide with little effort was judged to be very good (++), a gliding with little effort but occurring breakaway with good (+), a glide with moderate effort and higher breakaway torque with satisfactory (o), high force glide with sufficient (-), very poor (-) sticking.
- lubricant G6 could not be homogeneously coated onto the steel plate even with addition of surfactant, an approximately 0.1 ml drop of the lubricant was applied to the second side of the adhesive. By pressing the here untreated second steel plate of the lubricant drop was distributed on the second tape surface.
- the low viscosity non-aqueous lubricants G1, G2 and G5 have excellent sliding properties.
- the lubricants G3 and G4 with a viscosity above 10 Pa s show good sliding properties, but only after a breakaway torque occur, which they are within the scope of the invention.
- the adhesive K1, K2 and K4 and bondages are built up after only a short time.
- the adhesive K4 absorbs the lubricant more quickly, which leads to relatively high adhesive forces after one hour. However, this does not affect negatively the lubricity. From The adhesive K3 absorbs the lubricant more slowly, but also leads only to a small loss of shear strength.
- the difference in the rate of absorption was used in the bonding of a two-layer adhesive tape consisting of a layer K3 and a layer K4.
- the first side of the adhesive tape with the adhesive K4 was laminated analogously to the lubricity test on a here with 2 g / m 2 equipped with the lubricant G1 steel plate and stored for one minute under the above laboratory conditions. Then, the lubricity test was continued as described above with the lubricant G1. During the tangential movement, there was a very good sliding on the surface of the adhesive K3, while the adhesive K4 already sufficiently adhered to the likewise oiled surface of the first substrate, so that there was no displacement of the adhesive tape section.
