Definitions
- the present invention relates to a process for producing a coating composition or a precursor thereof usable in the automotive industry, the process comprising at least steps (1) to (7), namely preparing a recipe of a target formulation or retrieving such an existing recipe from a database ( 1), providing a container having a tag containing the prescription of the target formulation in electronically readable form (2), reading the tag electronically (3), providing reservoirs containing those components necessary to make the target formulation (4 ), Weighing these components into the provided container (5), creating an electronic record of the initial weighing (6) and creating an electronic documentation of the entire manufacturing process (7), the execution of (3), (5) and (6 ) by means of support software, which support comprises a control of the weight according to step (5), the recipe for each of the components weighed within (5) for the preparation of the target formulation, a predefined range of fault tolerance with respect to their weighed-in quantity and the initial weight the components in (5) are therefore within their respective predefined fault tolerance ranges.
- Coating compositions usually take place within research laboratories. Even in modern paint development laboratories and paint labs, such compositions or their precursors, such as pigment or effect pigment pastes, are prepared by a series of analog process steps, i. without a parent, automated
- Process control This includes the weighing of the individual components used for this purpose and the control of their stock and their procurement.
- the weighing of the components used in each case also takes place in modern paint laboratories, as a rule by means of a balance, which is not networked by computer technology, in combination with the use of a laboratory book, in which the target values of the weight of the individual components as well as the actual Values can be entered after the initial weight.
- This approach is partly due to the fact that the existing process control systems in companies in the chemical industry are usually based mainly on the needs of large-scale production, but not on the quite different needs of paint laboratories.
- process control systems including a weigh-in technique
- the functionality of process control systems is thus tailored to the scale of industrial scale, and therefore can not always satisfactorily capture the specific requirements of paint laboratories and so far is not readily transferable and applicable to the laboratory scale used therein.
- the reasons for this are, on the one hand, the much greater complexity and variety in such paint labs and the implementation of extensive series tests in comparison to large-scale production of individual large batches.
- the significantly smaller quantities of samples used within paint labs also play a significant role.
- test tables are generated with mostly generally available software such as Excel® from Microsoft, then printed out by the laboratory employee, the components provided in each case are weighed in succession based on these printouts, and the respective weighed positions checked off on the printout.
- the maintenance of the tabular test recording ie the documentation of the test history, is subject to the individual responsibility of the laboratory worker, but at the most it is subject to laboratory specifications.
- a qualitative evaluation of the target values and the actual values of the weighed-in recipe components usually does not take place here. Also a detection of the raw material batches used usually does not take place.
- Quality standards thus have a need to optimize and improve the development processes, in particular with regard to the work carried out by the laboratory staff in paint laboratories, such as the weighing of components for the production of coating compositions or precursors thereof.
- a first subject of the present invention is therefore a process for the preparation of a coating composition usable in the automotive industry or a precursor thereof, which process comprises at least steps (1) to (7), namely

- the method according to the invention enables the minimization of errors in the manual weighing of the individual components for the preparation of target formulations. Weighing errors often result from the fact that, although large amounts in the kg-scale can be weighed comparatively exactly to the desired value by the person entrusted with weighing, ie without "exploiting" a given error tolerance range of eg ⁇ 1 wt .-%. However, weighing errors often occur with smaller quantities, since the weight of such components is often already broken off before the setpoint in order to avoid overdosing.
- step (5) since the inventive method a systematic, visually present and easy to implement in practice accuracy in the weighing of the individual components and digitizing the previous analog and manual Weighing technology allows.

This can be done by direct retrieval as part of an existing recipe from a database. If a recipe of a target formulation is first created in step (1), this can be linked to an existing database and integrated within this database already existing predefined fault tolerance ranges of the components used within the recipe in the new recipe.

- step (4a) Through the reading process according to step (4a), it is possible to check before the weighing according to step (5) whether the correct components or correct storage containers are required for producing the target formulation. This can prevent incorrect weighing. In addition, it can be checked whether the respective storage container still contains a sufficient amount for the recipe of the target formulation of the respectively required component. Furthermore, it can be checked whether the correct order of addition of the components is adhered to according to the recipe.

- the course of the weight and the control of the weight according to step (5) can be visualized by means of an optical and dynamic progress bar or arrow, wherein in addition to the respective "target” specification of the weight also the current "is” weigh-in is displayed.
- This bar or arrow grows with increasing "actual” weight during the process of weighing.
- it changes its color from, for example, “yellow” (meaning: “target” specification not yet reached) to "green” (meaning: “actual” weigh-in is within the range of fault tolerance of the "target” specification) up to “Red” if this range of fault tolerance is exceeded and thus of the "target specification.
- An optional supplement with an acoustic signal reproduction for example according to PDC systems (Park Distance Control), is also possible.
- the course of the initial weight and the control of the weight according to step (5) are thus visually displayed by displaying a dynamic and in the course of performing step (5) growing and preferably colored progress bar or arrow, preferably next to the respective "target" - Specification of the weight according to the recipe of the target formulation of the weight and the current "actual" weight is displayed.
- a first check of the correct component addition and component sequence is preferably carried out as described above within the additional optional step (4a), for example by means of barcode scanning of the labels attached to the respective storage containers: for example, within step (4a) scanning of a wrong component (or the correct component, but in the wrong position within the order of their addition according to the recipe, it will Accordingly visually represented (error dialog display, for example, in red) and the respective employee is thereby made aware of his error before weighing.

As a result, bottlenecks and consequently delays during the preparation of the target formulations can be avoided.
- the inventive method allows in this way a batch tracing the raw materials used. In the case of conventional manufacturing and weighing procedures, this is often associated with a considerable additional effort.
- the printed test table associated with the analogue method of operation ie the specification of the weights to achieve the target formulation
- the printed test table associated with the analogue method of operation would require, in addition to checking off the weighed positions, a note of the respective batch number. Since these notes are usually needed only for the preparation of the target formulation and then disposed of, the notated data would have to be transferred in a second step in the test tables. This procedure is time-consuming and any necessary evaluation would also have to be done manually.
- Step (7) thus allows automated batch documentation, which is a clear advantage, especially in the course of a longer development, for example, to investigate and investigate unusual effects or test results more clearly and even at any later time after the target formulation has already been prepared is. Also, the adjustment of incorrect target formulations by making the paint system in the laboratory again in an identical manner with all the raw material batches used in production for this formulation is previously possible only with considerable raw material organization effort due to the purely analogue vision.
- the requirement of batch tracing can also be fully met in the production of target formulations in the laboratory.

Under a basecoat is therefore in particular a used in automotive painting and general industrial paint coloring and / or to understand coloring and an optical effect giving intermediate coating material. This is generally applied to a primed or primed metal or carbide mesh, and sometimes applied directly to the plastic substrate. Even old paints, which may still have to be pretreated (for example, by grinding), can serve as substrates. Meanwhile, it is quite common to apply more than one basecoat. Accordingly, in such a case, a first basecoat layer is the background for a second To protect the basecoat film in particular against environmental influences, at least one additional clearcoat film is applied to it.
- a precursor of a coating composition useful in the automotive industry is preferably a pigment and / or filler paste.

- pigment paste is known to the person skilled in the art and is defined, for example, in Rompp Lexikon, Paints and Printing Inks, Georg Thieme Verlag, 1998, 10th Edition, page 452: Pigment pastes are preparations of pigment mixtures in support materials such as polymers in which the pigments are in a higher concentration present as it corresponds to the later application.
- the subsequent use of pigment pastes is usually in the production of coating compositions such as basecoats.
- a pigment paste is thus to be distinguished from a coating composition such as a basecoat in that it is merely a precursor for making such a coating composition. A pigment paste as such can therefore not be used as a basecoat itself.
- pigment pastes the relative weight ratio of pigments to polymers is usually greater than in the coating compositions, for the production of which the paste is finally used.
- support materials such as polymers, which are also known as paste binders, and pigments
- water and / or organic solvents are usually present in the pigment paste.
- various additives such as wetting agents and / or thickeners can be used in a pigment paste.
- An effect pigment paste is a pigment paste containing at least one effect pigment pigment. A person skilled in the art is familiar with the term effect pigments. A corresponding definition can be found, for example, in Römpp Lexikon, Lacke und Druckmaschine, Georg Thieme Verlag, 1998, 10th Edition, pages 176 and 471.
- the effect pigments are preferably pigments which are optically effecting or have a color and optical effect, in particular an optically effecting effect.

- Water-based paints which can be prepared by the process according to the invention
- the coating composition obtainable by means of the process according to the invention is preferably a basecoat, in particular an aqueous basecoat (aqueous basecoat).
- Waterborne basecoats require both production scale and laboratory scale in the course of their development, adaptation and improvement so-called Operaweinwagen: This means that not all recipe ingredients can be weighed together in a container like a mixed container in succession, but are available as prefabricated partial mixtures at different temporal position additions have to. On a production scale, this is referred to as precharging, and in the laboratory also to partial weights. Such partial weighers are temporary semi-finished products and thus precursors of coating compositions in the context of the present invention. The reason for using the partial weights is that the raw materials of the water-based paints represent both hydrophilic (polar) and hydrophobic (non-polar) components. These can show intolerance and segregation among each other. Therefore, premixes and sequences of addition etc. are to be considered here.
- step (6) If the method according to the invention for producing such a partial weight is used as a precursor for the preparation of a waterborne basecoat material, according to step (6), an appropriate protocol for the initial weighting and, according to optional step (7), an electronic documentation of the entire manufacturing process is created only information is contained to what extent and to what extent all the requirements contained in the recipe of the target formulation have been fulfilled, but in which preferably also the consumption and the resulting current inventory of the quantities of all components used to produce the target formulation is recorded and documented.
- the information about the completed production of this preliminary stage can be incorporated into a database, preferably into that in which the recipes of the target formulations are contained.
- a water-based paint formulation usually consists of up to 30 individual positions, ie 30 components are needed to prepare the water-based paint.
- the further positions 6 to 15 and 16 to 28, on the other hand, are weighed in each case first in a separate container used as an auxiliary container for the preparation of two mutually different precursors (precursor 1: positions 6 to 15, precursor 2: positions 16 to 28). These two precursors 1 and 2 are then fed in this order to the master package, which already contains the positions 1 to 5 of the recipe. Subsequently, the positions 29-30 of the recipe after addition of the two precursors 1 and 2 are then added again regularly.
- precursors prepared by the process according to the invention can in turn be used after their preparation as starting components for the coating composition to be prepared.
- the container obtained after step (5) of the process according to the invention which contains a precursor prepared by the process according to the invention, can be used again as a reservoir for the preparation of another target formulation or sequence target formulation in step (4).
- the target formulation contained in the container obtainable after step (5) is at least one precursor for the preparation of a coating composition and, after its preparation within step (4), is contained in a reservoir Component used to prepare a coating composition. As mentioned above, this is particularly advantageous in the production of waterborne basecoats.
- the process according to the invention can thus preferably be run again in this case, wherein the precursor obtained after the first pass in the second pass is used as the starting component within step (4). Accordingly, the container obtained after step containing the precursor as a target formulation is used as a reservoir in step (4) within the second pass.
- step (5) it is preferably ensured within the method according to the invention that the respectively required quantities of precursors prepared in step (5) are available in sufficient quantity at the necessary time according to their positional order, in turn being used as components in step (4) of the method to be able to.
- step (6) it is preferably achieved by performing step (6) and, optionally, step (7) and incorporating the documentation on how the precursors are made into the database. This information can then be retrievably retrieved for later follow-up orders (production of further target formulations).
- step (7) it is preferably ensured (preferably by step (7)) that the replenishment of the amounts of precursor available is automatic and sufficient as it does in software-based weighing according to step (5) using storage containers according to step (4), which contain these precursors, losses may occur due to the non-100% residue-free transfer to the container within step (5). Therefore, it is preferably ensured that there must always be a slightly larger amount of the precursors than is actually required for the preparation of the coating composition.
- a reduction of the total throughput time ie the required duration of production of a Coating composition can be achieved by the preparation of a target formulation, which is a coating composition required to produce at least one precursor, is carried out by several people in parallel by means of the method according to the invention.
- This can be achieved by formulating a coating composition and the precursors required for this purpose as separate recipes for preparing mutually different target formulations. In this case, eliminates the previously necessary coordination and error frequency for the merger of all these precursors in a main order (preparation of the coating composition).
- step (3) of the method according to the invention it is possible to check whether all the components required for the coating composition as target formulation are present, and it is possible to evaluate within the optional step (4a) whether there is a sufficient amount of required precursor.
- employees A and B can each produce one of the precursors 1 and 2 in parallel (precursor 1: positions 6 to 15 of the basecoat; precursor 2: positions 16 to 28 of the basecoat, since these are separate within the process according to the invention)
- Employee C manufactures the 30-base basecoat, using precursors 1 and 2 as soon as they become available.
- Solvent-based clearcoats which can be prepared by the process according to the invention
- the coating composition obtainable by the process according to the invention is preferably a clearcoat, in particular a solvent-based clearcoat.
- Solvent-based clearcoats usually do not need any of the so-called sub-wagons, unlike water-based paints. However, clearcoats, like waterborne basecoats, often contain up to 30 or more individual items. In contrast to waterborne basecoats, the preparation of clearcoats can usually take place completely chronologically, ie as serial weighing in only one container within step (5).
- the wet-chemical composition of solvent-containing Coating systems, such as corresponding clearcoats are based on hydrophobic and, accordingly, non-polar feed components. Due to their similarity, these raw materials are usually miscible with each other indefinitely.
- a recipe of a target formulation for making a clear coat comprising 30 positions may be divided into three separate recipes of target formulations to make each a 10-position precursor. This can be done in parallel by 3 employees. The three precursors with ten positions thus produced are then reassembled in a final, special recombination step in an empty container (master container).
- the procedure for the above-mentioned partial weight loss processes for waterborne basecoats can therefore also be used analogously for orders without actually required partial weights for increasing efficiency by means of split orders.
- the method according to the invention can be used to produce a whole range of coating compositions which can be used in the automotive industry, such as, for example, electrodeposition paints, primers, fillers, basecoats, topcoats, including clearcoats.
- a dissolver batch (a dissolver is a special agitator for the purpose of predispersing solids in binders) is usually first prepared.
- the mixture of components used for the preparation is usually first finely dispersed via a horizontal mill to the desired grain fineness.
- the batch rate before the mill can deviate greatly from the resulting amount after the mill rubbing process (the millbase). This is due to incalculable losses during the grinding process.
- the subsequent completion of the ground material on the admixture of the final ingredients is called completion.
- the individual admixtures during the completion must be mathematically adjusted in advance of the amount of the resulting regrind. For this reason, the use of partial weights in the production of such coating compositions by means of the method according to the invention is also advantageous in this case.
- the millbase which is used to prepare a filler as a coating composition represents a precursor in the sense of the present invention. Before or after completion of this millbase, the possibility of topping up or reducing can be used.
- step (1) of the method a recipe is formulated according to which 5000 g of a filler is to be produced.
- the proportion of the partial weight of the Mahlgutansatzes from Dissolveransatz is 50 parts by weight of 100 parts by weight. This corresponds with a target amount of 5000 g thus 2500 g. After the grinding process, however, the yield of the millbase due to frictional losses is only 2000 g. In the recipe of the target formulation (completion shares), this millbase appears as a precursor in the form of a single position. If the underlying 100's formulation of this main order of the target formulation looks like this, then the TARGET / ACT re-calculation process shown below inevitably results to ensure that the recipe portions remain consistent with each other despite meal loss as planned receptively:
- step (4b) of adjusting the amounts specified within the recipe of the target formulation all of the components required to produce the target formulation according to step (4), if at least one of the components is available in a lesser amount than prescribed by the recipe.
- the given quantities within a target formulation can of course be increased if the amount specified therein is too small.
- the corresponding batch quantities, ie, first all partial weight (TEW) -relevant Mahlgutkomponenten be increased preferably by means of a function in the software, eg here from 2500 g to 3000 g yield after rubbing process. After submission of this resulting amount (3000 g) millbase and the remaining portions of the completion are automatically increased accordingly.
- the automatic conversion function saves time and primarily serves to prevent arithmetic errors that would require a costly new production.
- Pos. 1 regrind 50 parts> 2500 g 3000 g (+500 g increased yield)
- a varnish is to be prepared by mixing together the following components taking into account the following specifications (target formulation):
- Component 1 3000.0 g of mixed paint (colorless)
- Component 2 450.0 g color paste (white)
- Component 3 30.0 g color paste (black)
- Component 4 5.0 g color paste (red)
- the individual components for the production of the paint are weighed one after the other.
- a balance while a conventional laboratory balance is used which has a resolution of 0.01 g.
- Component 1 2970.0 g to 3030.0 g
- Component 2 445.5 g to 454.5 g
- Component 3 29.7 g to 30.3 g
- Component 4 4.95 g to 5.05 g
- the entrusted with the production of the paint and thus with the weight of the aforementioned components endeavor to weigh the components each in an amount as accurate as possible of the target formulation equivalent.
- other factors are limiting such as environmental influences (draft, vibrations, etc.) and the expertise of the respective employee. Due to these factors, there is usually no sample weight that corresponds exactly to the specifications of the target formulation. This has a comparatively great influence, in particular for those components which are weighed in comparatively small quantities (components 3 and 4 in the present example).
- components 3 and 4 in the real result of the initial weight is relatively accurate and comparatively close to the respective specifications.
- components 1 to 4 are weighed out in the following amounts: Component 1: 3000.3 g of mixed paint (colorless) -> in order (i.O.)
- Component 2 449.7 g color paste (white) i. O.
- Component 3 30.3 g color paste (black) i. O.
- Component 4 5.1 g color paste (red) - not i. O.
- the percentage deviation in relation to the target is greater than in the case of components 1 and 2.
- the weight of the components 3 and 4 is thus inaccurate than that of the components 1 and 2. In fact it is the employees are unable to weigh relatively smaller positions with the same accuracy.
- step (5) of the method according to the invention is - based on the components 1 to 4, which were used within the above comparative example V1 - that the permissible error tolerance in the initial weighing already from the first two positions (components 1 and 2) and thus contrary to the pursuit of maximum possible accuracy.
- the range of the error tolerance of ⁇ 1% is systematically taken into account already from the first position (component 1), starting at the point in time at which component 1 weighs in at 2970 g Since this is already within the range of the error tolerance for component 1: here, the employee entrusted with the initial weight is already indicated from the time when this initial weight of 2970 g is reached that this value is "in order (in the first place)". Thus, the weight of the component 1 can already be ended at this time.
- Component 1 2974.1 g of mixed paint (colorless) - in order (in the first place)
- Component 2 448.2 g color paste (white) i. O.
- Component 3 29.9 g Color Paste (Black) - i. O.
- Component 4 5.00 g color paste (red) i. O.
