Definitions

  • the invention relates to a method for applying a coating agent to the surface of a workpiece.
  • a coating agent is to be understood as meaning a wet-chemical coating material, in particular a lacquer.
  • Paints as such are known in many embodiments from the prior art. They are usually applied in a thin layer on the surface of a workpiece and form by a chemical reaction and / or physical change adhering to the surface of the workpiece solid film, which has a decorative and / or protective function depending on the application.
  • the main components of a paint are usually binders, solvents, pigments, fillers and other additives, such as paint aids.
  • lacquers may contain organic solvents and / or water or be solvent-free.
  • paint to the surface of a workpiece
  • the application of a paint to the surface of a workpiece is referred to as painting and may depend on the surface of the workpiece, the paint to be applied and the desired properties the later lacquer layer using a variety of methods. For example, by painting with a brush, by spraying with the help of sprayers or by flood, dipping, pouring or rolling.
  • the coating of metal strips or sheets can also be done by coil coating with stoving, in powder coating by electrostatic coating or sintering in the fluidized bed, and finally by the most commonly used in the automotive industry electrophoretic coating.
  • Smooth lacquer layers can be formed in particular by the dipping method.
  • the thickness of the salmon depends primarily on the viscosity and rheology of the paint and on the extraction speed of the workpiece from the dipping bath.
  • it is disadvantageous in the drip area of the workpiece to an unavoidable accumulation of paint, resulting in a generally unwanted thickening of the paint layer in this area.
  • the entire workpiece is wetted by the dipping process. This is always disadvantageous if not the entire workpiece, but only portions of the same are to be provided with a coating layer.
  • the spray process is suitable.
  • a spray cone is generated, which is directed to the surface to be coated with a mostly predeterminable compressed air pressure. In this way can specifically coated only partial areas of a workpiece surface, ie painted.
  • the spraying method has prevailed in many fields for the abovementioned advantage, and this irrespective of whether a protective or decorative surface coating is to be formed with the coating, the lacquer layers which can be produced by the spraying process also have a strength that is usually considerable. Particularly in comparison with the wavelength of the light perceptible to the human eye, the lacquer layer thicknesses obtainable by conventional methods are very large. This circumstance is disadvantageously noticeable, in particular, in the case of transparent coating systems, because the viewer perceives that the structural change in the workpiece surface caused by a coating application is often perceived as having a high gloss and "greasy" quality. Also, the appearance of orange peel effects can not always be completely avoided. Such effects are also perceived by the viewer as unpleasant and often lead to complaints.
  • Such methods for applying a coating agent to the surface of a workpiece are known for example from DE 37 27 632, US 4,389,234 and JP 61-249567.
  • DE 37 27 632 describes a method and an apparatus for coating thin-walled or small-sized glass containers.
  • the still-hot glass containers are taken directly from the forming process and placed in a coating tunnel which is open on both sides and in which they are subjected to a turbulent flow of a mixture of vaporized metal compound and air get abandoned.
  • a turbulent flow of a mixture of vaporized metal compound and air get abandoned In order to ensure the formation of a complete and uniform coating, it is provided that the glass containers are exposed during the course of the process two oppositely oriented flow paths.
  • a metering system is provided, from which the liquid metal compound is metered continuously into the air guiding chambers of the coating tunnel. From there, the mixture enters the coating tunnel and flows around the glass containers to be coated, forming a coating of colorless, transparent metal on them.
  • glass articles are coated in a coating tunnel.
  • the glass containers to be coated are guided by means of a conveyor belt through a hood forming the coating tunnel.
  • the side walls of the tunnel are provided with a plurality of mutually opposite coating agent-penetrating and suction, so that a guided through the hood glass container from different directions and each can be applied several times with a coating agent, wherein the unused coating agent from the tunnel for another Use is withdrawn.
  • a carrier gas usually air, is provided, into which the coating agent is introduced as vapor or atomized.
  • JP 61-249567 describes the formation of a closed, very thin coating on the surface of a workpiece.
  • the workpiece is guided in a coating chamber and a supersaturated aerosol atmosphere exposed.
  • an atomizer is provided, which mixes the originating from a reservoir coating agent finely divided into a pressurized gas stream.
  • the previously derived and indicated object is achieved by a method for applying a coating agent to the surface of a workpiece, in which the coating agent is finely divided mixed into a gas stream, the coating agent-gas mixture is guided in a relative to the surrounding atmosphere sealed volume space and a workpiece arranged within the volume space is surrounded by the coating agent / gas mixture, wherein the coating agent is finely distributed so that particles with a diameter of 10 -8 m to 10 -6 m are formed.
  • the coating agent to be applied is finely divided into particles having a particle diameter of 10-8 m to 10-6 m.
  • the particles are then mixed into a gas stream, so that an aerosol consisting of carrier gas and coating particles is formed. This is guided in a sealed against the surrounding atmosphere volume space. Within the volume space, the workpiece having the surface to be coated is arranged, which is now exposed to the aerosol atmosphere.
  • a closed surface coating is achieved, the layer thickness of the particle diameter of the coating composition accordingly in the few 10 nm range, preferably a few 100 nm range lie.
  • the formation of a closed surface coating can additionally be assisted by an electrical or electrostatic charging of the coating agent particles and / or of the workpiece to be coated.
  • the surface properties of workpieces can be changed in a targeted way.
  • surfaces of commodities may be coated with a colorless protective layer so that later cleaning of the article, such as wiping fingerprints, can be much easier and faster.
  • the surface of black plastic parts, such as the surface of car taps, or the surface of shiny metallic or matte, such as chromed surfaces can be much easier maintained and cleaned due to a seal made by the method according to the invention.
  • a coating agent-gas mixture according to the invention can be produced, for example, by a mechanical atomization of fine powders, by condensation of vapors when cooled below the dew point or freezing point, by combustion processes or spraying solutions or
  • the inventive method is suitable for coating a variety of flat or three-dimensional workpieces.
  • These can be made of plastic, metal, glass, ceramics, fiber products, textiles, polymers, stone, sandstone or concrete. Particularly good results can be achieved with materials which have reactive groups (eg hydroxyl or amino groups) on their surface. These include, for example, glass or ceramic surfaces.
  • the process can be used with metals in particular for aluminum, brass and chrome, but is particularly suitable for electroplated surfaces.
  • the adhesion of the coating agent to the surface of the workpiece is improved with increasing surface tension of the workpiece.
  • Examples of coatable with the process according to the invention workpieces are fittings, solar panels, glass covers, facades, decorative screens, display windows, car sheets, printing press plates, metal foils and nozzles.
  • the workpiece preferably has room temperature, but may also be introduced cooled or heated into the volume space in order to achieve a temperature difference between the workpiece and located in the volume space coating agent.
  • inventive method is suitable for use with coating compositions of any composition.
  • Particularly suitable coating compositions are those based on silanes, in particular organosilanes.
  • Organosilanes are bifunctional silicon compounds which can serve in paints and coatings as adhesion promoters between substrate and coating or as crosslinkers. Organosilanes can also take over the function of a co-binder as oligomers in hybrid coatings.
  • Suitable organosilanes are, in particular, organofunctional silanes and alkylsilanes. These are derived from silicic acid esters, wherein one or two alkoxy groups of the silicic acid ester are replaced by directly bonded alkyl or functionalized alkyl radicals.
  • Organofunctional silanes and alkylsilanes thereby obtain a bifunctionality that allows them to react with organic as well as inorganic materials or to organophilically modify via their alkyl moiety of organic materials.
  • Organosilanes preferably used according to the invention are preferably in the form of a liquid having a low viscosity.
  • reaction behavior is advantageous with respect to the organosilanes, it being possible for the silicon-functional group to hydrolyze in the presence of water or by surface moisture of substrates (eg glass, metal, fillers or pigments).
  • substrates eg glass, metal, fillers or pigments.
  • the alkoxy groups are gradually split off to form alcohol and the silane converted into the reactive form, the silanol.
  • the silanol formed can then be fixed via a chemical bond on the surface of inorganic substrates.
  • the coating compositions which are preferably used in the process according to the invention may contain, in addition to the silanes or organosilanes, further constituents, such as resins or inorganic compounds, such as aluminum oxides (eg A1203) or titanium oxide.
  • organofunctional silanes such that one or more silicon atoms are replaced by metal atoms.
  • the properties of the layer system to be achieved can be specifically changed and adapted to the respective requirements.
  • the frequency maximum at certain viscosity and temperature is at a droplet diameter of 500 nm.
  • the lower limit is 200 nm, the upper limit is about 2 pm.
  • the frequency peak of the mass spectrum is over 2 ⁇ m.
  • the essential mass fraction of the transported coating agent is thus in the relatively few large drops. The gravitational effect is particularly pronounced in such a composition of a coating agent gas mixture.
  • the way in which the coating agent / gas mixture is brought into contact with the workpiece should be matched to the predominant coating effect. This is preferably done by Measures to ensure that each surface section of the workpiece comes into contact with all particles of different diameters. This is done above all by means of measures which bring about a uniform distribution of all particle sizes in the part of the volume space in which the workpiece is located.
  • the spectrum of particle sizes can be influenced in particular by the choice of the temperature and the pressure. Higher temperatures and lower viscosities result in a smaller particle spectrum. This can support the condensation effect.
  • the dominance of a coating effect can be brought about when a temperature gradient between the workpiece and the volume space is set.
  • the coating process is carried out under substantially atmospheric pressure. This leads to a good adhesion of the coating agent to the workpiece.
  • the coating agent-gas mixture is blown into the volume space.
  • This allows the introduction of a pre-mixed and in the composition of the specific individual case coordinated coating agent-gas mixture.
  • an increased movement of the individual suspended particles can be achieved by blowing, so that sets an overall uniform distribution of the coating agent particles within the volume space. This causes advantageously the formation of a more uniform, d. H. in particular a more uniform thin coating agent layer.
  • the coating agent-gas mixture is circulated within the volume space. Also by this measure, the coating agent-gas mixture is distributed evenly in an advantageous manner in the volume space, so that an equally uniform coating is ensured.
  • the larger the diameter of the coating agent particles the stronger their tendency to settle towards the bottom of the volume space.
  • a circulation of the coating agent-gas mixture thus takes place not only as a function of the density of the mixture, but also as a function of the diameter of the particles, wherein the necessity of a circulation increases with increasing particle diameter.
  • the coating agent-gas mixture is guided in a closed circuit.
  • the coating agent / gas mixture is introduced under pressure into the volume space via at least one supply line and the resulting coating agent / gas mixture jet circulates the coating agent / gas mixture within the volume space.
  • the coating agent-gas mixture jet is directed onto an inner surface of the volume space.
  • the jet can bring about an advantageous long-range circulation and distribution of the coating agent / gas mixture. If, for example, a sphere is used as the volume space, then the jet can be deflected along the inner surface so that a vortex filling the vortex is formed.
  • two coating agent-gas mixture jets flow in the opposite direction.
  • the jets it is possible for the jets to collide with one another and cause strong turbulences, which results in the above-mentioned advantages of circulation during the coating and, secondly, it is possible to produce mixture jets which run parallel to one another and run in opposite directions cause far-reaching turbulence over the entire volume space.
  • the opposing jets By arranging the opposing jets on different sides to the central axis of the volume space, a spacious vortex can be generated which fills the entire volume space.
  • the at least one coating agent-gas mixture jet enters the volume space in a direction inclined to the horizontal. This holds advantageous options depending on the shape of the volume space and the workpiece to be coated to determine the circulation of the coating agent-gas mixture. So even areas close to the floor and the ceiling can be supplied with the necessary particle density.
  • a coating agent-gas mixture jet in a direction inclined to the horizontal upward and a second coating agent-gas mixture jet is introduced in a direction inclined downwards to the horizontal direction.
  • the workpieces are positioned within the volume space by means of a frame.
  • the workpieces can already be suitably fixed outside the volume space and be positioned with the frame in the volume space.
  • a suitable frame design can be selected in order to achieve optimum circulation of the coating agent / gas mixture.
  • the workpieces are moved in the volume space, preferably rotated on a frame about one or more axes.
  • this leads to all surfaces of a flat or three-dimensional Workpiece at least once during the coating in an "upward" facing position. Since the gravitational effect of the coating is essentially achieved by the fact that heavy drops gravitational impact from the top of "upward" facing surfaces, the aforementioned movement of the workpieces leads to a uniform coating of all surfaces.
  • no movement is required. Nevertheless, a movement of the workpiece can also be provided in these methods.
  • the temperature of the coating agent is set to a temperature of 15 to 23 C. This leads to an intensification of the gravitational effect, which is particularly advantageous when the workpiece is moved in the volume space according to the manner described immediately above.
  • the temperature of the coating agent is adjusted to 22 to 40 C, preferably 35 to 40 C. This reduces the particle size of the coating composition and supports the condensation effect. Thus, even in volume spaces in which the workpieces are not moved, they are well coated.
  • the coating agent / gas mixture is conveyed as a function of a predefinable function via a supply line into the volume space and after flowing through the volume space via an exhaust gas line is sucked off.
  • a precise control or regulation of the mixture atmosphere is made possible within the volume space and so can be done if necessary, a Nachbine or upstream suction.
  • a decisive decision criterion here is the density of the coating agent-gas mixture.
  • the coating agent-gas mixture is filtered after aspiration from the volume space. This ensures that particles do not enter the environment unintentionally.
  • an activated carbon filter is preferred.
  • the density of the coating agent-gas mixture is detected in the volume space and readjusted to set a predeterminable value in case of need. Maintaining a predetermined density is of crucial importance for the coating quality achievable with the method according to the invention, in that the mixture density, which is in a function ratio relative to the residence time of the workpiece in the volume space, has a decisive influence on the layer thickness formed per unit time. Although this dependence can be varied by additional circulation motions of the coating agent / gas mixture in the volume space, in particular the density of the mixture is a preferred measure for determining how many coating agent particles per volume of part are contained in the gas. Preferably, the density of the coating agent-gas mixture is detected optically. This type of capture is easy to perform and reliable over.
