Abstract
The invention relates to a method for producing coated metal surfaces at a coating speed of at least 25 m per minute during the application of a pre-treating agent to a cleaned and/or pickled metal surface. The inventive method is characterized by applying at least one pre-treating agent to at least one surface of a metal body after cleaning and/or pickling the metal surface to be treated. At least one lacquer layer is applied to a part of the pre-treated surface, the coating produced only by the pre-treating agent and not by the lacquer being used as the treatment layer instead of a priming or pre-treatment layer. The invention further relates to a method for producing coated metal surfaces at a coating speed of at least 25 m per minute during the application of a pre-treating agent to a cleaned and/or pickled metal surface. The inventive method is characterized by applying at least one pre-treating agent to at least one surface of a metal body after cleaning and/or pickling the metal surface to be treated. At least one lacquer layer is applied to at least a part of the pre-treated surface, the coating produced only by the pre-treating agent being used as the treatment layer instead of a priming or pre-treatment layer.
Description
ol WO 01/43888 PCT/EP00/12745 o B - 1 -
The present invention relates to a method for producing coated metal surfaces in which the coating can be carried 5 . out at high speed. Such coatings are often used under the description “coil coating” to coat strip materials. : The known high-speed coating methods have the disadvantage that the pretreatment and the priming (primer) are applied in two separate steps.
The object of the invention is to provide a process for the large-scale industrial production of lacquered strip materials in which the pretreatment and priming can be 15 .applied in only one work stage. : © This object is achieved by a process for producing coated oo metal surfaces at a coating speed of at least 25 m per : oo minute in the application of a pretreatment agent to a
E 20 cleaned and/or pickled metal surface, which is. g
Co characterised in that at least one pretreatment agent, in Co particular a solution and/or dispersion, is applied to at : : least one surface of a metal body after a cleaning and/or a pickling of the metal surface to be treated and at least : 25 one lacquer layer is then applied to a part of the oo pretreated surface, with the coating produced only using a - oo pretreatment agent and not using a lacquer being used, } instead of a pretreatment layer and a priming layer, as oo - ‘treatment layer. | a - oo Furthermore the object is achieved by a process for
So producing coated metal surfaces at a coating speed of at oo least 25 m per minute in the application of a pretreatment : ) : agent to a cleaned and/or pickled metal surface, which is ; . 35 characterised in that at least one pretreatment agent, in 0
A WO 01/43888 PCT/EP00/12745 Co - - 2 - Co © particular a solution and/or dispersion, is applied to at : least one surface of a metal body after a cleaning and/or a pickling of the metal surface to be treated and at least one lacquer layer is then applied to a part of the pretreated surface, with the coating treated with a : pretreatment agent being used, instead of a pretreatment : layer and a priming layer, as treatment layer. :
Preferably the pretreated surface or surfaces form one side oo 10 of a strip, in which optionally at least one of the narrow " edge surfaces of the strip may also be partially : pretreated.
The coating speed is preferably 40 to 600 m per minute, particularly preferably 75 to 160 m per minute. The - treatment layer thereby assumes the functions of the primer. The other part of the pretreated surface is subsequently no longer coated with a lacquer in the strip coating device.
The method according to the invention may be employed so "that moisture or residual moisture is retained in the applied pretreatment layer until lacquering is performed, in order to adjust the necessary electrical conductivity of the pretreated surface for the application of the lacquer + layer. | ) i The metal surface may before the pretreatment contain in particular aluminium, iron, copper, magnesium, zinc and/or oe 30 tin and may preferably consist of an aluminium alloy, a
Co oo hot-dip galvanised or electrolytically galvanised iron - i. - ’ material, a steel, a full zinc material in the form of oo strips or metal sheets, or tinplate. In this connection = the bodies may be flat or shaped, or may be provided with h | 35 recesses, such as for example with a perforated structure. :
o : _ 3 - }
Co The recesses of a perforated plate may all have the same geometry and size, or may optionally also have different : geometries and sizes, for example circular holes, elongate holes or slits. : :
The cleaning and/or the pickling of the metal surfaces may be carried out by spraying and/or brushing with a cleaning - and/or pickling solution or immersion in a. bath of this solution. | ) : | )
The pretreatment of the cleaned and/or pickled surface may be performed by spraying and squeezing out, for example with a roller, by spraying and blowing off, for example
CL with compressed air, by immersion and squeezing out, for ~ ~~ example with a roller, by immersion and blowing off, for oo example with compressed air or in a roll-coat process. Co
With the roll-coat process the treatment liquid is applied with a coating roller in or against the direction of movement of the strip. In all these process variants, no | Ce subsequent rinsing is performed in order to prevent removing and/or damaging the applied layer and to avoid B rinse water loaded with chemicals, which for environmental B reasons, would have to be post-treated in a complex . . procedure.

The pretreatment agent may be a preparation containing a . polymer dispersion with at least one resin from the group consisting of acrylate, epoxide, phenol, polyester, oo silicone polyester, polyurethane, styrene and urea- - formaldehyde based resin or a mixture thereof and/or a mixed polymer. The preparation contains, apart from : volatile constituents, a non-volatile film-forming mixture. i
The preparation may contain at least one resin as solution and/or as dispersion. The preparation may contain, apart i | 35 from resin(s), at least one inorganic additive in dissolved

I carbonate, chromate, oxide, phosphate, silicate or sulfate.
The pretreatment agent may also be a resin-free iE 5 . preparation, with it being possible for the preparation to contain aluminium, fluoride, hydrofluoric acid, phosphate, phosphoric acid, trivalent and/or hexavalent chromate, oo chromic acid, silicate, silane, tannin, titanium, zinc,’ zirconium and/or self-organising molecules, for example . 10 based on phosphonates, carboxylic acids, thiols and/or silanes.
For the application to a metal strip a different pretreatment agent may be chosen for one side of the strip : 15 than for the other side, with it being possible for the side not intended to be subsequently lacquered to be coated oo with a pretreatment agent containing organic resin. For
Co + example only one side of the strip, say the upper side, is Co possibly lacquered, whereas, on the opposite side, the x 20 pretreatment acts as a final treatment. :
After the application of the treatment agent the layer may either be partially dried or completely dried. This may be carried out - especially with uniform strip speeds and when
Co 25 using existing ovens - by.a shorter residence time under the active drying conditions, by a lower temperature in the . oven, and/or by a reduced air movement for the drying of ) : ; the strip. - - 30 ‘Preferably at least one side of the pretreated surface is - coated with an organic coating that hardens sufficiently y ) | and/or crosslinks in a time from 1 second up to 3 minutes, E particularly preferably from 5 seconds up to 2 minutes.

For the coating of the pretreated surface, a powder lacquer, in particular a powder lacquer having good mechanical properties, high scratch resistance, good adhesion and high flexibility as regards forming and
BE 5 shaping, is preferably applied and stoved. The powder . lacquer may in this connection be applied by spraying, fluidised-bed powder sintering and/or powder cloud technology and stoved. Powder cloud technology is described in, inter alia, EP-A-0 678 466. Instead of by
C10. conventional circulating air drying or fluidised air ‘drying, the stoving may be carried out by, in particular by conductive drying using magnetic materials, and/or by infra-red drying, in particular in the near infra-red Ce (NIR) . a . | The pretreatment layer and/or treatment layer may, after Co - complete drying, have a layer thickness in the range from Co 0.1 to 50 um, preferably in the range from 0.5 to 10 pm, particularly preferably in the range from 1 to 3 pm. oo After the crosslinking, the stoved lacquer layer that is CL contained on the pre-treatment layer may have a layer thickness in the range from 5 to 1000 pm, preferably in the range from 10 to 400 pm, and particularly preferably in the oo 25 range from 15 to 60 um. When using PVC plastisols it is J oo possible to recommend selection of a layer thickness in the oo - range from 100 to 300 pm. oo : | In a preferred embodiment of the method according to the a | 30 invention a one-layer cover lacquer is applied as a single B so lacquer to the strip to be coated. oo A treatment layer that performs the function of a -

There may be used for the powder lacquer a powder for a : single-colour unstructured coating, a powder for a multicolour unstructured coating, and/or a powder for a multicolour structured coating. : : : The coated surface may be protected, in particular against mechanical damage, for example during storage, transportation and further processing, at least partially : by a film or adhesive film. :
The coated bodies may optionally be shaped, cut - especially in the longitudinal and/or transverse direction ‘ - and optionally re-formed, for example beaded, roll- SR formed, deep-drawn and/or edged. "20 .
