Definitions

  • the present invention relates to a process for the preparation and application of a coating composition, in particular for protecting surfaces against undesired contamination and for facilitating removal of such contamination. More particularly, this invention relates to the protection of surfaces of suspension and support organs, that are used in high-pressure spray treatments, like painting or cleaning.
  • WO 92/08555 a protective coating is described, that can be applied in the spray-painting of cars and buildings etc.
  • Spray-paint treatments require considerable preparation, where one has to make sure that parts of a car or a building that are to be left out of the treatment, are protected against overspray. This is often done with masks and tape of paper or plastic. The application of those is a labour-intensive and time-consuming chore, that has to be performed with great accuracy.
  • the masking material that is described in this reference comprises polyvinyl alcohol, glycerin or tri-ethylene alcohol a surface-active agent and water. It is applied to the surface that is to be protected and subsequently dried. When the thus treated surface has been into contact with paint, the paint is left to dry, after which it can be removed by pealing it off or with water.
  • the composition can be used as coatings which can be applied by electrostatic spray of dry powder.
  • a coating composition comprising a combination of a wet lacquer and a powder lacquer, both lacquers being baked together, the wet lacquer comprising a primer and the powder lacquer comprising a fluoropolymer, in particular a polytetrafluoroethylene, a fluorinated ethane-propane copolymer or comprising a perfluoroalkoxy or a mixture of two or more of these polymers.
  • the invention is characterized in that a combination of a wet lacquer and a powder lacquer is applied to the surface, which combination comprises a primer, as well as fluoropolymer, in particular a polytetrafluoroethylene, a fluorinated ethane-propane copolymer or a perfluoroalkoxy or a mixture of two or more of these polymers.
  • Tetrafluorethylene polymer better known by the name Teflon, possesses, as is known, good anti-caking characteristics. However, the characteristics of this material alone did not prove sufficient to provide a coating composition that achieves the set aim.
  • Fluorinated ethane-propane copolymer and perfluoroalkoxy are coating materials that also display favourable anti-caking characteristics, but of which the characteristics alone are not sufficient to allow to obtain a coating composition that reaches the set aim.
  • the preparation of the protective coating composition comprises the following steps:
  • the weight ratio of the wet lacquer and the dry lacquer and also of the tetrafluorethylene polymer and polyfluoranioxide amongst themselves is not critical for this invention and can be selected from a wide range.
  • the coat thickness of the wet lacquer after baking is 7-15 ⁇ m, more preferably about 10 ⁇ m, and of the powder lacquer after baking about 12-20 ⁇ m, preferably about 15 ⁇ m.
  • a coat thickness that is too small is at the expense of the lifespan of the coating, and has an adverse influence on the anti-caking characteristics of the coating composition.
  • the coating composition according to the invention may, if so desired, contain other components, like further anti-caking agents, filling agents, adhesion agents, colouring agents, a hardener, a top coat etc.
  • this surface Prior to application of the coating composition according to the invention to the surface to be treated, this surface is preferably cleaned thoroughly beforehand.
  • This cleaning may be performed in many ways, which are known to the man skilled in the art. It is particularly important that the surfaces to be treated are degreased.
  • the degreasing may also be performed in many ways, attention having to be given to the nature of the material and of the dirt.
  • metal objects, aluminium excluded, are degreased thermally in an oven at a temperature of 300-400°C.
  • Objects made of aluminium are preferably degreased chemically using well-known solvents.
  • a further cleaning method is blasting of the objects to be treated, for example with silicium oxide (sand) or aluminium oxide as blasting agent.
  • a suitable blasting agent is korund aluminium oxide type 24, preferably the purest kind to avoid corrosion of the underlying layer. The blasting is preferably performed at a pressure of about 3,5 bar based on an impact with a depth of about 10 ⁇ m.
  • the two cleaning steps described above are preferably performed consecutively on the surfaces to be treated, the degreasing step usually being performed first. After blasting, the surfaces to be treated are treated further as quickly as possible, to avoid oxidation.
  • the zinc layer preferably contains two components, viz. zinc in powder form and a hardener in liquid form, which is known to the man skilled in the art.
  • the two components are mixed, preferably with a mixer, so that a liquid product is formed.
  • a suitable zinc:hardener mixing ratio is for example about 1:2.
  • the thus obtained mixture is preferably sprayed on the surfaces to be treated immediately after blasting.
  • the objects are allowed to dry and harden, for example for 12 hours at room temperature. In order to accelerate the drying process the temperature can be increased or water can be misted on the objects to be treated.
  • the first layer is applied that forms part of the coating composition according to the invention, viz. the primer coat.
  • primers are suitable for use in said coating composition, resulting in a choice from a wide range.
  • Suitable primers comprise for example diaceton, methylisobutylietone and dyrrplidone.
  • Highly suitable primers are solvent-based primers, for example a Primer Black 423-604 BL of Dupont.
  • the primer may comprise a suitable hardener.
  • the primer is preferably sprayed on the surface to be treated, more preferably with a spray pressure of about 3,5 bar.
  • the primer coat thickness is preferably 10 to 15 ⁇ m after baking at increased temperature.
  • the dry lacquer of polytetrafluoroethylene, a fluorinated ethane-propane copolymer or a perfluoroalkoxy or a mixture of two or more of these polymers is applied, preferably also by spraying the lacquer onto the surface.
  • a usual technique for its application is electrostatic spraying.
  • the powders of these compounds are melted beforehand, both melts being mixed in some cases, after which the melt of one of both substances or of the mixture is sprayed on.
  • the mixture can also be prepared by previously mixing the powders of the two components, then letting that mixture melt. If so desired, a suitable solvent is added in order to be able to spray the compound(s) better.
  • the thickness of the applied dry lacquer is about 20 ⁇ m in molten state.
  • the thus formed coat is allowed to rest for about 30 minutes, before the baking process is started.
  • the baking process constitutes an important part of the preparation process, excessive temperature swings having to be guarded against. It is important that the part, of which the surface is to be coated, is not heated too fast, in order to bring about that the part has a homogenous temperature, and a homogenous melt is obtained.
  • the temperature of the baking process is preferably within the range of 300 to 370°C, more preferably between 315 and 340°C.
  • the baking time is usually about 10 to 15 minutes.
  • a temperature gradient is applied, according to which the temperature is raised from room temperature to about 340°C in about 1 hour, after which the temperature is held at this highest value for about 10 minutes. Next the product is air cooled. This process takes about 1 hour, during which the obtained coating composition hardens.
  • the thus prepared coating composition has highly favourable characteristics, especially with respect to the removal of paint overspray and of dirt of various nature. These materials can easily be removed from a surface that has been provided with the coating composition according to the invention, for example by applying a high-pressure water cleaner or alternatively with air under high pressure. The paint that is to be removed is best removed when it has dried. If so desired, the materials are removed from the protective coating by pealing them off.
  • the protective coating composition according to the invention can be used for many applications, but is especially suitable for metal.
  • These applications comprise, but are not limited to, the covering of suspension and mounting systems, like those present on spray lines, that are led through ovens during the painting process, casu quo lacquering process.
  • Such spraying lines can be automated, whereby efficient use can be made of conveyor belt systems (including screening plates and conveyor belt chains), which in such cases are preferably also protected with a coating composition according to the invention.
  • the applications further comprise grates, for example floor grates and panels in spray cabins (for applications of primer, as well as of base lacquer and clear lacquer); filter holders; robot parts; spray turbines, ducts, ventilators of exhaust systems, water curtains and "flow coat" cabins.
  • a suspension rack was degreased for 60 minutes by heating in an oven at 350°C. After cooling the rack was subjected to sand blasting until an impact of 10-15 ⁇ m was reached. Next a coat of a primer was applied, type Black 423-604 BL of Dupont, with a thickness of about 15 ⁇ m. Over the wet primer coat a layer of a PFA powder lacquer was applied, that had a thickness after baking of about 15 ⁇ m. After application of the powder lacquer the suspension rack was heated for about 60 minutes in an oven at 350°C to harden the coating.
