Description

Verfahren zur Beseitigung von Lackschäden Process for removing paint damage
BESCHREIBUNGDESCRIPTION
Die Erfindung betrifft ein Verfahren zur wenigstens mittel¬ fristigen Beseitigung von Steinschlägen und kratzerartigen Beschädigungen in Lackoberflächen, insbesondere Autolackschich¬ ten unter Herabsetzung der durch die Beschädigung bedingten Korrosionsgefahr.The invention relates to a method for at least medium-term removal of stone chips and scratch-like damage in paint surfaces, in particular car paint layers, while reducing the risk of corrosion due to the damage.
Kratzer und andere kleinere Beschädigungen auf Autolacken, beispielsweise Steinschläge, stellen insofern ein erhebliches Problem dar als die gründliche Beseitigung unverhältnismäßig teuer ist im Vergleich zur Kleinheit der Beschädigung. Soweit derartige Lackschichtverletzungen nicht durch die Farbpigment- haltige Schicht des Lackes hindurchgehen, lassen sie sich vielfach durch Auspolieren mit handelsüblichen Poliermitteln entfernen. Tiefere Kratzer müssen jedoch durch Lackierung behandelt werden. Weiter ist es möglich, mit entsprechend zugeschnittenen Lackfolien solche Beschädigungen zu überkleben. Hierdurch wird jedoch die Glätte der Oberfläche verschlechtert, so daß häufig die Beschädigung trotzdem sichtbar bleibt.Scratches and other minor damage to car paints, such as stone chips, pose a significant problem in that thorough removal is disproportionately expensive compared to the smallness of the damage. Insofar as such lacquer layer injuries do not pass through the layer of lacquer containing paint pigment, they can often be removed by polishing with commercially available polishing agents. However, deeper scratches must be treated by painting. It is also possible to mask over such damage with appropriately cut lacquer films. This, however, deteriorates the smoothness of the surface, so that the damage often remains visible.
Es besteht daher Bedarf an einem ganz einfachen Verfahren zur wenigstens mittelfristigen Beseitigung von derartigen Lack¬ schäden. Unter mittelfristig wird hierbei verstanden, daß auch bei einer Mehrzahl von normalen Autowäschen die Beschädigung optisch nicht wieder auftritt und ein Korrosionsangriff auf das darunter liegende Blech verhindert oder verzögert wird, bis eine entsprechende Nachbehandlung in gleicher Weise erfolgt, oder eine Neulackierung zur langfristigen Beseitigung des Kratzers oder Steinschlags in Betracht kommt.There is therefore a need for a very simple method for at least medium-term removal of such paint damage. In the medium term, it is understood that even in the case of a number of normal car washes, the damage does not appear again and a corrosion attack on the underlying metal sheet is prevented or delayed until a corresponding aftertreatment is carried out in the same way, or a repainting to remove the scratch in the long term or falling rocks.
Der Erfindung liegt daher die Aufgabe zugrunde, ein einfaches Verfahren zur wenigstens mittelfristigen Beseitigung von Stein¬ schlägen und kratzerartigen Beschädigungen in Lackoberflächen, insbesondere Autolackschichten unter Herabsetzung der Korro¬ sionsgefahr zu schaffen. Gelöst wird diese Aufgabe erfindungs¬ gemäß dadurch, daß man die Beschädigung auf der Lackoberfläche mit einem bindemittelhaltigen Farbmalstift möglichst ähnlicher Färbung wie die des Lacks abdeckt und gegebenenfalls überschüs¬ siges Stiftmaterial auspoliert.The invention is therefore based on the object of a simple method for at least medium-term removal of stone chips and scratch-like damage in paint surfaces, In particular to create car paint layers while reducing the risk of corrosion. This object is achieved according to the invention in that the damage to the paint surface is covered with a binder-containing colored pencil with a coloration that is as similar as possible to that of the paint, and if necessary, excess pencil material is polished out.
Überraschenderweise ist es möglich mit handelsüblichen binde¬ mittelhaltigen Farbmalstiften, wie sie typischerweise für Künstler und Schüler zur Verfügung stehen, die genannten kratzerartigen Beschädigungen praktisch unsichtbar zu machen und gleichzeitig die Gefahr eines korrosiven Angriffs durch die Beschädigung wesentlich zu verringern. Ebenfalls überraschen¬ derweise zeigt es sich hierbei, daß erfindungsgemäß behandelnde Lackoberflächen eine unerwartet große Beständigkeit aufweisen. So wurde bei bis auf das Blech durchgehenden Kratzern in einem Autolack eine erfindungsgemäße Behandlung mit handelsüblichem Farbmalstift entsprechender Farbe vorgenommen und anschließend die Waschbeständigkeit in einer automatischen Waschanlage ermittelt. Nach 20 Wäschen war der Kratzer noch vollständig abgedeckt und kein blankes Metall sichtbar.Surprisingly, it is possible with commercially available binder-containing colored crayons, as are typically available for artists and schoolchildren, to make the scratch-like damage mentioned practically invisible and at the same time to substantially reduce the risk of a corrosive attack from the damage. Also surprisingly, it is found here that lacquer surfaces treated according to the invention have an unexpectedly high resistance. Thus, in the case of scratches that go all the way down to the sheet metal in a car paint, a treatment according to the invention was carried out using a commercially available colored pencil of the appropriate color and the wash resistance was then determined in an automatic washing system. After 20 washes, the scratch was still completely covered and no bare metal was visible.
Daß erfindungsgemäß auch ein erstaunlich guter Korrosionsschutz erzielt wird, zeigt folgender Versuch: Ein Testblech (Stahl¬ blech mit Glasurit Epoxi Grund grundiert und mit Glasurit Acryllack 2:1 mit Härter lackiert; Gesamtlackdicke 180 μm) wurde mit einem Kratzer von ca. 1 mm Breite versehen, der bis zum Blech Lack und Grundierung entfernt hatte. Die Hälfte der Länge dieses Kratzers wurde mit einem Farbmalstift (Rheita Wachsmalkreide Art. -Nr. 6678 weiß) abgedeckt und das überschüs¬ sige Wachs auspoliert. Anschließend wurde dieses Testblech einer Salzsprühnebelprüfung nach DIN 53 167 unterzogen. Nach 24 Stunden war bei der abgedeckten Hälfte des Kratzers keinerlei Korrosion zu erkennen. Der unbehandelte Teil des Kratzers zeigte Korrosion und der Kratzer war bereits ca. 1 mm breit von Rost unterwandert. Analoge Ergebnisse wurden erhalten, wenn anstelle der Rheita Wachsmalkreide ein Farbmalstift der Fa. Sakura Color Products, Inc., No. XSC verwendet wurde.The following experiment shows that surprisingly good corrosion protection is also achieved according to the invention: A test sheet (steel sheet primed with Glasurit Epoxi primer and coated with Glasurit acrylic paint 2: 1 with hardener; total paint thickness 180 μm) was scratched with a width of approx. 1 mm provided that had removed paint and primer up to the sheet. Half the length of this scratch was covered with a colored pencil (Rheita wax crayon art. No. 6678 white) and the excess wax was polished out. This test plate was then subjected to a salt spray test in accordance with DIN 53 167. After 24 hours, no corrosion was visible on the covered half of the scratch. The untreated part of the scratch showed corrosion and the scratch was already infiltrated by rust about 1 mm wide. Analogous results were obtained when Instead of the Rheita wax crayon, a colored pencil from Sakura Color Products, Inc., No. XSC was used.
Farbmalstifte der im Rahmen der Erfindung verwendeten Art bestehen im Prinzip aus einer Bindemittelmatrix, vorzugsweise auf Basis von Wachs oder/und Harz, in der Pigmente entsprechen¬ der Färbung mit guter Lichtechtheit eingebettet sind. Geeignete Bindemittelmatrices für die Farbmalstifte sind solche, die einerseits die Farbpigmente gut miteinander verbinden, anderer¬ seits auch die Festigkeits- und Abriebeigenschaften aufweisen, die für Malstifte charakteristisch sind. Die Bindemittel können anorganisch oder organisch, natürlich oder synthetisch sein. Die bevorzugten Bindemittel auf Basis von Wachs oder/und Karz entsprechend der Defintion für Wachse und Harze gemäß Römpp, Chemie-Lexikon, 9. Auflage, Seite 4972 bezüglich der Wachse und Seite 1737 bezüglich der Harze. Sowohl natürliche Wachse und Harze als auch chemisch modifizierte oder synthetische Wachse und Harze, wie insbesondere Hartwachse, erwiesen sich als geeignet. Die Stifte können fettlösliche oder fettunlösliche, anorganische oder organische Pigmente, z.B. Ruß oder Titan¬ dioxid, enthalten, evtl. zusammen mit Schlämmkreide und sind häufig mit Bienenwachs, Japan-Wachs, Carnauba-Wachs oder Paraf¬ fin, Kolophonium, Alkyd- , Acryl- oder Epoxidharzen als Binde¬ mittel hergestellt. Die Herstellung der geeigneten Farbmal¬ stifte erfolgt üblicherweise durch Dispergieren des Pigments in einer Menge von zweckmäßig 2,5 bis 10 Gew.-% in dem Material der Bindemittelmatrix z.B. und Erhitzen bis zur plastischen oder flüssigen Konsistenz oder unter Zusatz von Lösemitteln. Inbesondere erfolgt dies in der Harz- oder/und Wachsschmelze unter Verwendung von Dispergiergeräten. Für die erfindungs- gemäße Behandlung wählt man eine Farbe der Farbmalstifte, die der Lackfarbe möglichst nahe kommt. Erstaunlicherweise genügt dabei eine Farbähnlichkeit, um die Beschädigung im Lack un¬ sichtbar zu machen. Eine völlige Farbgleicheit ist nicht nötig.Color crayons of the type used in the context of the invention consist in principle of a binder matrix, preferably based on wax or / and resin, in which pigments corresponding to the coloring are embedded with good lightfastness. Suitable binder matrices for the colored crayons are those which on the one hand bond the color pigments well with one another and on the other hand also have the strength and abrasion properties which are characteristic of crayons. The binders can be inorganic or organic, natural or synthetic. The preferred binders based on wax or / and carcass as defined for waxes and resins according to Römpp, Chemie-Lexikon, 9th edition, page 4972 regarding waxes and page 1737 regarding resins. Both natural waxes and resins as well as chemically modified or synthetic waxes and resins, such as hard waxes in particular, have been found to be suitable. The sticks can be fat-soluble or fat-insoluble, inorganic or organic pigments, e.g. Carbon black or titanium dioxide, possibly together with sludge chalk, and are often made with beeswax, Japanese wax, carnauba wax or paraffin, rosin, alkyd, acrylic or epoxy resins as binders. The suitable colored crayons are usually produced by dispersing the pigment in an amount of appropriately 2.5 to 10% by weight in the material of the binder matrix, e.g. and heating to plastic or liquid consistency or with the addition of solvents. In particular, this takes place in the resin or / and wax melt using dispersing devices. For the treatment according to the invention, one chooses a color of the colored pencils that comes as close as possible to the paint color. Surprisingly, a similarity of color is sufficient to make the damage in the paint invisible. Complete color consistency is not necessary.
Das Auftragen auf die Lackbeschädigung kann durch einfaches kaltes Aufmalen erfolgen, typischerweise indem man senkrecht zum Kratzer aufmalt und dabei soviel Farbmalstiftmasse aufträgt bis der Kratzer zumindestens plan abgedeckt ist. Eventuell überschüssige Farbmalstifmenge kann in der für Lackoberflä¬ chenbehandlung übliche Weise auspoliert werden.The paint damage can be applied by simple cold painting, typically by vertical paint on the scratch and apply enough colored pencil until the scratch is at least covered flat. Any excess amount of colored pencil can be polished out in the manner customary for lacquer surface treatment.
Gut geeignete Wachszusammensetzungen erhält man beispielsweise aus der Kombination eines überwiegenden Anteils von Paraffin mit kleineren Anteilen an microkristallinem Wachs und Poly- vinyletherwachs. Eine andere besonders geeignete Zusammen¬ setzung besteht aus etwa 90 % einer Mischung von weichem Polyethylenhomopolymerwachs und microkristallinem Wachs im Verhältnis von etwa 1 : 5 bis 1 : 1 mit einem Polyethylenhomo- polymer fettartiger Konsistenz. Der Farbstoffgehalt liegt zweckmäßig zwischen 1 und 10 Gew.-%, bevorzugt zwischen 3 und 7 Gew. -%.Well-suited wax compositions are obtained, for example, from the combination of a predominant proportion of paraffin with smaller proportions of microcrystalline wax and polyvinyl ether wax. Another particularly suitable composition consists of approximately 90% of a mixture of soft polyethylene homopolymer wax and microcrystalline wax in a ratio of approximately 1: 5 to 1: 1 with a polyethylene homopolymer of fat-like consistency. The dye content is advantageously between 1 and 10% by weight, preferably between 3 and 7% by weight.
Außer dem erwähnten Bindemittel und der Farbe können die erfindungsgemäß verwendeten Farbmalstifte zusätzlich noch Füllstoffe, wie sie dem Fachmann bekannt sind, beispielsweise Calciumcarbonat, enthalten.In addition to the binder and the color mentioned, the colored crayons used according to the invention can additionally contain fillers as are known to the person skilled in the art, for example calcium carbonate.
Wie oben bereits erwähnt, erwiesen sich die erfindungsgemäß abgedeckten Beschädigungen als überraschend dauerhaft behan¬ delt. Da nach 20 Waschzyklen in handelsüblichen automatischen Waschanlagen die Kratzer noch nicht wieder sichtbar wurden, ist damit zu rechnen, daß je nach Häufigkeit der vorgenommenen Autowäsche bis zu einem Jahr vergehen kann, ehe der Kratzer wieder sichtbar wird und einer evtl. Neubehandlung bedarf.As already mentioned above, the damage covered according to the invention proved to be surprisingly permanently treated. Since the scratches have not yet become visible again after 20 washing cycles in commercially available automatic washing systems, it can be expected that, depending on the frequency of the car wash carried out, it can take up to a year before the scratch becomes visible again and may require a new treatment.
Das erfindungsgemäße Verfahren eignet sich nicht nur für Krat¬ zer auf Autolacken, sondern auch für die Behandlung anderer zerkratzter Lackoberflächen, insbesondere bei Motorrädern, Fahrrädern, Maschinen und dergleichen. Falls gewünscht, lassen sich die Farbmalstiftfarben auch leicht wieder entfernen durch Anwendung von Lackreinigungsmitteln, wie sie z.B. zur Entfer¬ nung von Schutzwachsschichten auf Autolacken bekannt sind. Durch das erfindungsgemäße Verfahren wird eine einfache, bil¬ lige und wenigstens mittelfristig zuverlässige Beseitigung von Kratzern und ähnlichen kleinflächigen Beschädigungen auf Lacken möglich und dadurch wird in vielen Fällen die sehr aufwendige und teure Neulackierung erübrigt oder doch für einen großen Zeitraum hinausgeschoben.The method according to the invention is suitable not only for scratches on car paints, but also for the treatment of other scratched paint surfaces, in particular on motorcycles, bicycles, machines and the like. If desired, the colored pencil colors can also be easily removed again by using paint cleaning agents, such as are known, for example, for removing protective wax layers on car paints. The method according to the invention enables simple, inexpensive and, at least in the medium term, reliable removal of scratches and similar small-area damage to paints, and in many cases this eliminates the very complex and expensive repainting or at least postpones it for a long period of time.
