Definitions
- the object of the present invention is a method and a system for adhesive bonding of substrates that allows the manufacture of adhesive bonding products for substrates formed by a covering support, such as a panel or a profile, and a covering material, such as a sheet or foil, both adhered by means of a glue, providing a high quality in the surface finish of the adhesive bonding product.
- a covering support such as a panel or a profile
- a covering material such as a sheet or foil
- the method and system for adhesive bonding of substrates object of the present invention is especially indicated in those products that comprise a substrate that has to be postformed. Likewise, it is especially indicated for high-gloss, transparent or similar coating materials, in which, due to their own characteristics, it is possible to easily visualize coating application defects.
- the method and system for adhesive bonding of substrates object of the present invention is applicable in the field of manufacturing products for construction and furniture, such as panels for furniture, doors and floors, profiles for door and window frames, etc. .
- glues are usually applied to the coating material and/or to the substrate to be coated and, subsequently, said coating is applied to the panel or profile.
- the glues have to be in a liquid state to be able to be applied, spread, smoothed, penetrate well, etc. on the substrates. After application, solidification and curing take place in order to achieve the necessary adhesive force (when this is available). mechanism) of the tail.
- the curing of the glue or adhesive is a process of polymerization or internal crosslinking of the glue. Solidification implies the use of physical methods to bring the glue from a liquid state to a solid state, such as, for example, evaporation or lowering its temperature.
- Viscosity arises in order to measure the resistance to movement of the glue particles.
- Tack stickiness
- tack is the bond strength of the adhesive with outside elements. It is, so to speak, what "bites” the tail. It is determined by the polarity of the molecules that form the tail, Van der Waals forces, etc.
- adhesive strength is the strength of the adhesive bond between the two substrates to be bonded.
- the adhesive strength of an adhesive or glue is determined by the lower of the values between tackiness and internal cohesion.
- the adhesives have a characteristic known as “open time”. This is the maximum time available between its liquid state at the beginning of its application (less viscous) and an intermediate point (more viscous), in a less liquid state (because, for example, a certain amount of water has evaporated in the case of PVAc glues, or the temperature has been lowered in the case of hot-melt glues or their curing has advanced), during which said adhesive allows operations to be carried out prior to the final bonding without being considered degraded. As already introduced, depending on the specific needs of the union, some queues or others are used with some values or others of the parameters mentioned above.
- the initial internal cohesion is very low since the glue is liquid (low viscosity).
- a white water-based glue “stains” (due to stickiness) the panel and the foil that you want to glue on it, but these are not initially strongly joined, they can be separated while the glue is not yet dry (low internal cohesion/viscosity).
- the glue dries (or cools and/or cures, that is to say polymerizing, in the case of a hot-applied adhesive (type hotmelt)) the viscosity increases and, thus, its internal cohesion until it reaches the solid state and polymerization total (if it has a polymerization mechanism).
- the glue From the application of the glue to its total solidification and curing (if any), there may be an initial phase where the internal cohesion is less than the stickiness of the glue. As the glue solidifies and, where appropriate, cures, either by evaporation, cooling, polymerization, etc. once the internal cohesion is greater than the stickiness, the weakest link in the union between panel and foil is said stickiness.
- an adhesive does not occur simultaneously. If an adhesive is available in a low-viscosity state, it can be spread/smoothed very well, but then, although it has adhesion capacity on the surface on which the glue is applied (tackiness), it does not have a strong internal cohesion until not increase its viscosity. And, conversely, when an adhesive with a certain tackiness and high internal cohesion (high viscosity) is available, the adhesive can no longer be easily spread/smoothed.
- the glue When the glue is applied on the panel or on the covering material by means of a roller (see Figure 1), the glue contacts the material at the point of application (P), with a contact surface (C) between the material and the applied layer of glue.
- the glue On said contact surface (C), the glue is initially fixed to the material by capillarity; however, the upper surface (S) of the glue layer remains initially stuck, also by capillarity forces, to the applicator roller.
- the layer of glue acquires the speed of the material (this material is normally being moved by means of rollers, a conveyor belt or other means of movement), while that the top surface (S) of the glue layer still has the same roller speed.
- the force of fixing the glue, by capillarity, to the roller is lower (the material from which the applicator rollers are made is non-stick) than the force of sticking by capillarity of the glue to the material on which it is applied; thus, as the top surface (S) of the tail attempts to advance in the direction given by the roller, it detaches from the roller generating a structure with crest/valley geometry, repeating this process throughout the time that the glue is applied to the material.
- Imperfections or structural defects in the glue are normally corrected by smoothing the glue after application. In a certain application, if it is not possible to smooth because the viscosity does not allow it, or it is simply a process where there is no smoothing, it is more likely, as has already been explained, that there is structuring of the glue if there is more of it than if there is less
- glue in stripes consists of the appearance of stripes of glue on the panel or on the coating (depending on the substrate on which the glue is applied), these stripes being of greater and lesser grammage, perpendicular to the longitudinal direction of the direction of travel of the panel or coating. This is caused by the existence of a lack of uniformity in the continuity of the longitudinal advance provided by the different elements involved in the process: different transmissions, substrate, covering element, coil brakes, etc., due to the interference produced between they. If the glue is viscous, these defects are more clearly manifested, while if it is less viscous, it fades better. This manifests itself in the final product as what is known as the “shutter effect” (fishbone).
- this defect consists of the appearance of air bubbles between the covering material and the glue or between the panel and the glue (depending on the substrate where the glue is initially applied). This defect mainly occurs with rigid coating materials.
- the present invention refers to a method and a system for adhesive bonding of substrates.
- the method of adhesive bonding of substrates object of the present invention comprises:
- the method comprises applying radiation curing means to the adhesive layer to selectively partially cure said adhesive layer, said selected and partial curing being effected prior to positioning the first substrate on the second substrate.
- selected and partial curing is performed by means of the curing means before positioning.
- the curing is carried out with a selected or predetermined degree of curing without reaching a total or complete curing before positioning. That is, for example, the adhesive layer can be cured before positioning by at least 50% or, preferably, at least 75%, etc., this corresponds to the degree of polymerization achieved, in percentage with respect to complete polymerization of the adhesive layer material is, respectively, at least 50% or 75%.
- a higher percentage of curing or polymerization favors the increase in viscosity of the adhesive layer and therefore its internal cohesion.
- This application of the curing means is carried out by radiation, that is, the adhesive used is configured for curing or polymerization by application of radiation. Radiation allows the application of curing energy in an effective way to produce a fast enough or accelerated cure in correspondence with the typical times of the industrial processes necessary for the positioning of the substrates to be bonded, especially for the bonding of coating materials, such as continuous sheets or sheets, and covering supports, such as panels or profiles. These processing times can be on the order of seconds.
- any type of radiation can be used to cure the adhesive used.
- curing by electromagnetic radiation for example, by UV or IR, or corpuscular radiation, such as with electrons (EB, "Electron Beam"), is contemplated.
- the adhesive layer can finish curing, for example also by applying radiation that can pass through the coating substrate.
- the invention allows to provide an adequate viscosity of selectable shape before positioning without impairing the stickiness and adhesive strength of the substrates.
- the invention provides versatility to the adhesive bonding method in that it allows the use of a wide variety of adhesives to achieve sufficient internal cohesion in a controlled manner, unlike the state of the art in which to increase cohesion internal viscosity is increased, for example, by cooling the glue before positioning in the case of hot melt glues, which impairs tack, or high initial viscosity glues are available to provide high internal cohesion, having adequate tack , at the time of positioning. Radiation allows curing to be accelerated in a controlled manner to increase internal cohesion before positioning without compromising tackiness and bond strength.
- the adhesive may have an additional curing mechanism which, in particular, may be activated before and/or after positioning.
- a dual cure mechanism PUR adhesive with additional moisture reaction cure can be used.
- An example of such an adhesive is commercially available under the brand name "Dual Curing" from Henkel.
- any other adhesive with an additional curing mechanism can be used. In this sense, for example, curing by mixing an additional component with the adhesive (eg water), curing by evaporation, etc.
- radiation curing means for example, the use of radiation emission lamps, for example, UV, LED or electric arc discharge radiation lamps, IR, NIR radiation lamps, etc., is contemplated.
- additional curing means for example, the use of humidifiers, evaporators, etc. is contemplated.
- the method object of the present invention comprises, in order to position the first substrate on the second substrate, postforming by means of postforming means at least one strip of the first substrate on at least one contour of the second substrate.
- the method of adhesive bonding of substrates object of the present invention comprises applying curing means on the adhesive layer in correspondence with the at least one strip of the first substrate prior to (and/or during) its postforming on the at least one contour of the second substrate.
- postforming is meant the set of operations to mold, adapt or couple the first substrate to the geometry of the second substrate, so that the first substrate covers the second substrate in those strips, sections or contours where initially, with the simple disposition of the first substrate on the second substrate, the second substrate was not covered by the first substrate.
- the procedure described it is possible to significantly increase the adherence strength of the first substrate in those strips subjected to postforming. This is especially helpful taking into account that, due to the elastic character and/or the shape memory, the first substrate may have a strong tendency to detach from the second substrate in those contours where it has been postformed.
- the adhesive can be applied with a very low viscosity grade that allows smoothing, or at least minimizes the effects due to the application itself, this not assuming a problem that causes a low adhesive force, especially in the postforming areas, since these are subjected to the curing media.
- This characteristic allows “playing" with two factors that intervene in the curing of the adhesive, namely: the curing power of the curing means and the time that elapses between the application of the curing means and the positioning of the first substrate on the second substrate, so that the adhesive strength of the adhesive is enhanced, especially at the time postforming occurs.
- the substrate adhesive bonding method comprises postforming in several stages, by means of the postforming means, different strips of the first substrate on different contours of the second substrate.
- the method of the invention comprises carrying out at least one second application of curing means between two stages of postforming.
- This characteristic allows the curing means to be applied in the instants immediately prior to the postforming of each strip of the first substrate to be postformed, thus having the ideal adhesive force in each strip to be postformed at the ideal moment, that is, immediately before of the postforming operation of said strip.
- the method of adhesive bonding of substrates comprises applying the curing means on a first strip of the first substrate that is not to be postformed, in particular in combination with at least one strip of the first substrate that is to be postformed.
- This characteristic allows the fringe of the first substrate that is not going to be postformed to be fixed very firmly to the second substrate, so that relative displacements between the first substrate and the second substrate are prevented in the event that the fringes that are going to be postformed pull strongly from the non-postformed fringe positioned on the second substrate.
- the method of adhesive bonding of substrates comprises smoothing the adhesive layer (all or part of it) immediately after its application on the first substrate and/or on the second substrate.
- the finish presented by the first substrate after being positioned or postformed on the second substrate is improved, avoiding the appearance and/or perception of defects due to the application of the glue itself, for example, the structuring of the adhesive layer .
- the first substrate is a coating material and the second substrate is a coating support on which the coating material is positioned.
- the covering support can be in the form of, for example, a profile or a panel.
- the covering material can be in the form of, for example, a sheet or foil.
- the adhesive bonding process according to the invention makes it possible to obtain adhesive bonding products such as laminated panels and coated profiles.
- the invention is applicable, for example, to wood panels, chipboard, HDF, MDF, aluminum, iron or plastic plates, wood profiles, HDF, MDF, PVC, aluminum, etc.
- a panel can be understood as a product with a substantially flat shape, with relatively large dimensions in width and length (normally longer than wide), and a certain thickness. By profile it is possible to understand an oblong-shaped product, where its greatest dimension is the length and its thickness and width are similar.
- a laminated panel can be understood as a panel with a cover, which can be flat or postformed. if, in addition to the substantially flat surface, its edges are also covered, etc. In coated profiles, their covering generally undergoes postforming.
- the present invention also relates to an adhesive substrate bonding system, being applicable to substrates in which a first substrate is a coating material, in particular, a sheet, and a second substrate is a coating support, in particular , a panel, on which the covering material is positioned.
- a first substrate is a coating material, in particular, a sheet
- a second substrate is a coating support, in particular , a panel, on which the covering material is positioned.
- the substrate adhesive bonding system comprises means for applying a layer of adhesive on the coating material and/or on the covering support, and means for positioning the coating material on the covering support.

- the method of adhesive bonding of substrates object of the present invention provides for the application of curing means (13) of the adhesive layer (1) in those strips of the adhesive layer (1) located on corresponding strips the cover sheet (2) that will be postformed to adapt to corresponding strips, sections or contours (14) of the panel (3).
- the curing means (13) may comprise means of emitting infrared radiation (IR, NIR), means of emitting ultraviolet radiation (UV) or another type of radiation. These curing means are configured to partially cure the adhesive in a selected manner, allowing a selected radiation energy to be applied to the adhesive layer.
