Definitions

  • the present invention relates to a continuous coating process at least one face of at least one strip by a mono fluid film or multilayer of crosslinkable polymer free of solvent or diluent and the softening temperature is above 50 ° C.
  • crosslinkable polymers to be hardened by heat treatment, by irradiation (UV radiation, electron beam %), after their application on the strip or by any other suitable process.
  • crosslinkable organic coatings such as paints or varnishes for example
  • paints or varnishes for example
  • a technique particularly used to deposit coatings with base of crosslinkable polymers free of solvent or diluent on a strip running is dusting. This technique consists in applying on tape a layer of polymer in powder form and then melt the polymer to re-spread it, and cook it for a few minutes at a temperature conventionally between 180 and 200 ° C so as to form a film.
  • This process consists in forming a crosslinkable polymer film melted by forced flow through a nozzle supplied with crosslinkable polymer melted either in an extruder or in a barrel void, on a cylinder preferably deformable surface applicator in contact with the surface of the strip to be coated. Transfer of the film formed by forced flow on the strip in scrolling is achieved by friction of the applicator cylinder and the strip, the scrolling of the two surfaces taking place in opposite directions, we then speak of reverse transfer (reverse in French). Cooking these polymers is carried out under conditions different from those of powder polymers standard; The cooking temperature is higher, around 230 to 270 ° C, and the cooking time much shorter, of the order of 10 to 60 s.
  • This reverse transfer coating process does not allow use standard powder polymers whose viscosity is too high high so that they can be extruded without risk of crosslinking in good conditions, i.e. with sufficient flow and pressure drop acceptable.
  • Solvent-free crosslinkable polymer formulations or diluent and whose particularity is to present a temperature at the start of higher crosslinking than that of powder polymers, as well as a viscosity have therefore been developed for this type of process.
  • the transfer process reverse remains difficult to implement, because we are still forced to heat the polymer to decrease its viscosity before forming a film by forced flow through the nozzle.
  • This process has the disadvantage of requiring very precise adjustment of the temperatures at the barrel or extruder, and at the nozzle. In addition, it does not make it possible to obtain coatings having a state always satisfactory surface area.
  • the present invention therefore aims to remedy the drawbacks prior art methods by providing a method of continuous coating of strips with a crosslinkable polymer free of solvent or diluent and whose softening temperature is higher at 50 ° C., which makes it possible to avoid any risk of the start of crosslinking of the polymer untimely before film formation, and to obtain a thin film of polymer cross-linked of uniform thickness and having a surface state free of craters.
  • the inventors have demonstrated that the addition of this temporary additive strongly reduces the viscosity of the polymer. From then on, it becomes possible increase the difference between the polymer film formation temperature crosslinkable and the temperature at which the polymer begins to crosslink by decreasing the polymer film formation temperature, which reduces the risk of crosslinking before film formation. So completely unexpected, the inventors have also found that by adding to the polymer crosslinkable a temporary additive with a boiling point included between the polymer film formation temperature minus 30 ° C and the temperature at the start of crosslinking of the polymer, the formation of craters in the crosslinked polymer film.
  • the temporary additive not only acts as a temporary plasticizer of the polymer, but also improves the surface appearance of the film.
  • the invention applies not only to metal strips, as for example steel, aluminum or an aluminum alloy, but also glass, plastic, plywood, or other suitable material, and the tape may have been previously painted or covered with a coating on one or two faces.
  • the solvent or diluent-free crosslinkable polymer can be crosslinkable thermally, or even by irradiation (UV or beam electrons).
  • irradiation UV or beam electrons
  • the compositions thermosets based on hydroxylated polyesters and blocked isocyanates and reference will be made to application WO95 / 21706 for a general description of products of this type, well known to those skilled in the art.
  • Polymers crosslinkable by irradiation can be radical systems or cationic, even hybrid systems.
  • the polymer can usually contain fillers, pigments, additives such as catalysts, plasticizers, stabilizers or any other known additive.
  • additive is understood to mean temporary, an additive that is added to the crosslinkable polymer, before formation of polymer film, and that we do not find, or almost not, in the composition of the crosslinked polymer film. This temporary additive is neither a solvent or diluent of the crosslinkable polymer.
  • the polymers used in this process have temperatures of softening, start of flow and start of different crosslinking.
  • the temperature at the start of crosslinking is the temperature from which an increase in viscosity is observed more than 10% in less than 15 min.
  • the polymers used in the context of the present invention are such that their softening temperature is higher than 50 ° C, which means that they are solid or very viscous at ambient temperature.
  • the strip is continuously scrolled on at least one support, and a fluid film of the said strip is deposited on the strip.
  • a temporary additive is added to the crosslinkable polymer before the film is formed, the boiling point T e of which is between the formation temperature T F of the polymer film mixed with the temporary additive minus 30 ° C, and the start temperature of crosslinking of the polymer T r . Since the crosslinkable polymer does not dissolve in the temporary additive, a homogeneous mixture is not formed.
  • This temporary additive acts as a temporary plasticizer for the polymer, making it less viscous, which makes it possible to melt the polymer / temporary additive mixture in the extruder or in the barrel-void, at a temperature T F of at least 10 °. C lower than the formation temperature T fo of the polymer film not mixed with a temporary additive.
  • the temporary additive produces significant foaming of the polymer.
  • the degassing of the polymer is thus facilitated before the crosslinking of the polymer, and a crosslinked polymer film free of craters is obtained.
  • the inventors have demonstrated that when the boiling point T e of the temporary additive is equal to or greater than the temperature at which the crosslinking begins to cross-link with the polymer, the additive does not have time to act and it generates numerous craters by rupture of the already crosslinked polymer film.
  • the boiling point T e of the temporary additive is preferably equal to the forming temperature T F of the polymer film mixed with the temporary additive more or less 20 ° C. In fact, when the boiling point T e of the temporary additive is lower than the formation temperature T F of the polymer film mixed with the temporary additive minus 20 ° C., the additive tends to vaporize in the 'extruder or in the barrel emptier. The temporary additive still acts as a temporary plasticizer for the polymer, but loses its effect on the surface appearance of the polymer film.
  • the boiling point T e of the temporary additive is chosen as a function of the crosslinkable polymer according to the invention of which it is desired to form a film by forced flow. It is between 70 and 155 ° C, preferably between 90 and 120 ° C.
  • the temporary additive retained is water.
  • the temporary additive is preferably added in liquid form in a proportion between 1 and 5% by weight of the crosslinkable polymer, preferably between 2 and 4%.
