Definitions

  • the present invention concerns an improved method of painting applicable to elements formed from synthetic plastics materials, in particular, motor-vehicle body components made from composites, which avoids the risk of bubbles and/or blisters forming in the layer/layers of paint/paints.
  • the invention also relates to elements formed from painted plastics material, which have a high quality of surface finish and do not require, except in exceptional cases, subsequent repairs to the paintwork.
  • a base layer of an electroconductive material is applied directly to the surfaces of the plastics elements to be painted, this base usually comprising a single-component conductive primer which polymerises at a relatively high temperature (approximately 150°C).
  • the primer is spread in a layer of predetermined thickness (approximately 30 microns) and the treated element is then stoved in an oven, causing polymerisation of the primer layer which hardens to form a porous, transparent, conductive film on the surface of the plastics element to be painted.
  • the element may then be painted by conventional methods as if it were an element made from sheet steel; this also improves the adhesion of the layers of paint applied successively to the surface of the element.
  • the elements are again stoved at a high temperature (150°C) to cause the polymerisation of the paint layers.
  • the aim of the invention is to provide an improved method of painting elements made from synthetic plastics materials, in particular vehicle body parts made from composites, which does not have the disadvantages described, in particular being free from the risk of bubbles forming in the paint layer during the stoving stage.
  • the invention therefore provides a method of painting applicable to elements made from synthetic plastics material, in particular motor vehicle parts made from composites, as claimed in claim 1. Therefore, firstly, at least one base layer of a predetermined thickness of a polymerisable electroconductive material is applied to a surface of a said element to be painted and, subsequently at least one layer of paint is applied on top of the said base layer of polymerisable material; then
  • the said element to be painted is formed from a material based on thermosetting vinyl ester/polyester resins
  • the said second polymerisable material is constituted by a catalysed two-component polyurethane transparent paint which is completely polymerisable by heating to just 60°C.
  • the said second polymerisable material is applied to a layer formed by a polyester-based adhesion promoter which is applied directly to the surface to be painted.
  • the invention also relates to a painted element as claimed in Claim 8.
  • the application of the catalysed two-component polyurethane paint layer directly to the surface to be painted (with the interposition solely of the adhesion promoter) and its polymerisation before the application of the conventional layers of primer and paint to the surface to be painted allows a gas-impermeable layer to be formed on the surface itself, forming a gas-tight seal over the surface pores which may contain unpolymerised or partially-polymerised monomers.
  • the gases produced are no longer able to reach the painted surface and pass through the porous primer layer to penetrate the layers of paint being polymerised and so form the known bubbles.
  • the polymerisation of the layer of gas-impermeable material at a low temperature (about 60°C), by virtue of the use of catalysed paints, also guarantees that no monomers can vaporise during the polymerisation of this sealing layer, risking localised damage in the layer which is still being polymerised, which could mean that the layer itself is not completely impermeable.
  • the reference numeral 1 indicates an element formed from a synthetic plastics material, for example, a panel pressed from a composite material and forming a vehicle body part, for example, of a motor vehicle, such as a bonnet, a door, etc.
  • the composites are considered, for simplicity, as a subclass of synthetic materials being, as is known, constituted by a reinforcing agent (glass, carbon, kevlar fibres, etc, regardless of how it is formed and distributed), encapsulated in a matrix constituted by one or more synthetic plastics resins obtained by the polymerisation of one or more monomers.
  • the panel or element 1 has a surface 2 covered by a paint coating 3 (possibly constituted by a plurality of superposed thinner layers of diverse materials); the surface 2 also contains pores 4 (only one of which is illustrated on an enlarged scale in Figure 1), at least some of which are partially filled with grains 5 of unpolymerised or only partially polymerised monomers; the grains 5 are formed from the same monomers as those used to form the resin/resins constituting the synthetic plastics base material from which (with the addition of the fillers) the element or panel 1 is made, and are the inevitable result of the known process for forming the panel or element 1 which is, for example, obtained by injection moulding, compression moulding, or injection-compression moulding.
  • the resin/resins forming the element or panel 1 are thermosetting vinyl ester/polyester resins as the element/panel 1 is moulded from a composite of the SMC, BMC or similar type.
  • the grain 5 vaporises creating gases (shown by the arrows 6) which, together with any air which may be trapped in the pore 4, expand and leave the pore 4, causing the coating 3 to swell which, as it is in the polymerising phase, is soft and plastic, although already mostly impermeable to gases; the gases 6 are thus not able to escape and they collect above the pore 4 and below the coating 3, creating a bubble 7.
  • the sizes of the bubbles 7 are an order of magnitude greater than those in the pores 4, which may vary from several microns to several millimetres: consequently, the bubbles 7 which form are between 1 and 10 millimetres in diameter or more.
  • a coating 3a is formed according to the invention on the surface 2 and, starting with the layer adjacent the surface 2, comprises two superimposed films B and A; the film A corresponds to conventional coatings, such as that in Figure 1, while the film B includes, in turn, a first continuous layer 10 applied directly to the surface 2 to cover it completely, being approximately 30 microns thick and formed from a polyester-based adhesion promoter ("Barrier"), for example, 487567 from the firm PPG Industries Inc, USA, and a second layer 11, also continuous and applied directly to the layer 10 so as to cover the surface 2 completely, being between 30 and 40 microns thick and formed from a material which polymerises at low temperature (approximately 60°C) and is impermeable to gaseous substances such that the layer 10 is completely gas-impermeable.
  • Barrier polyester-based adhesion promoter
  • second layer 11 also continuous and applied directly to the layer 10 so as to cover the surface 2 completely, being between 30 and 40 microns thick and formed from a material which polymerises
  • the layer 11 is formed from a catalysed two-component transparent polyurethane paint, such as, for example, 228003 obtained from PPG Industries Inc.
  • the film A instead, is, as already stated, constituted by a conventional multi-layer coating including, in the present case: a first layer 12 of thickness which may vary between 20 and 30 microns formed from an electrically-conductive polymerisable primer of the single-component type, for example, 487538, also from PPG Industries Inc, having a stoving temperature (for polymerisation) of about 150°C; a second layer 13, approximately 40 microns thick, formed from an undercoat paint, for example, "base coat” 400085/1 from HERBERTS GmbH, WUPPERTAL (D); a third layer 14, approximately 30 microns thick, formed from enamel and defining the real paint layer; and a surface layer 15 of approximately 30 microns thick, formed from a protective transparent polymer, for example, a "lacquer" of any known type.
  • the layer 10 is first of all applied, for example, by spraying to the surface 2 of the untreated element or panel 1 to be painted and then the layer 11 of two-component paint, which is applied by a "wet on wet” technique, that is, while the underlying film of material just applied is still wet due to the, as yet, incomplete evaporation of the solvent used.
  • the element 1, with only the layers 10 and 11 covering the surface 2 completely, is then stoved in an oven at a temperature which causes the rapid polymerisation of the material forming the layer 11; since one is dealing with a catalysed paint, the latter polymerises completely in approximately 45 minutes on heating of the element 1 to merely 60°C.
  • the element 1 is cooled and the layer 12 of conductive primer is first applied thereto in a known way followed by the layers 13, 14, 15 of paint proper; these layers, starting from the base layer 12, are not however applied directly to the surface 2, as in the prior art, but to the layer 11 which, as already said, is completely impermeable to gases when fully polymerised; instead, the layer 12, which acts as a base for the in-line application of the three layers of paint 13, 14 and 15 by the same known methods as for body parts made from sheet steel is, as is known, porous and therefore permeable to gaseous substances which are able to diffuse through it, in the direction of the thickness, as already described in Figure 1.
