Definitions

  • the present invention relates to a method for printing markings on rubber articles, in particular tires, the marking being applied by means of color. Furthermore, the present invention relates to a tire which can be produced by such a method, and to a label which is suitable for printing on rubber articles.
  • markings on rubber articles in particular on vehicle tires
  • the labels are either glued onto the tires or sprayed onto the tires using templates. In both cases, the markings can be easily removed from the tire, so that a permanent connection between the marking and the tire cannot be achieved. There is therefore a need for a label that can be permanently applied to a rubber article.
  • Such a permanent connection is possible, for example, if the part of the rubber article to be labeled is is colored.
  • the part of the rubber article to be labeled is colored.
  • the application of markings to rubber articles by means of appropriate coloring of individual sections of the rubber article reaches a limit where the marking has a complicated geometric configuration or where a lettering is to be used as the marking. In such cases, the application of the marking on the rubber article would be very complicated and therefore very expensive.
  • vulcanettes Another known way of applying markings to rubber articles is to use vulcanettes.
  • the marking is first printed on the vulcanette.
  • the so-called vulcanette is inserted into the vulcanization mold together with the rubber article to be produced and connected to the rubber article in the subsequent vulcanization process.
  • This creates a durable connection between the rubber article and the label.
  • this method again has the disadvantage that the application of the marking on the rubber article is quite complex and therefore expensive.
  • the present invention is therefore based on the object of providing a method for printing labels on rubber articles, in which a durable connection between the label and the rubber article kel can be achieved. Furthermore . the process should be easy to carry out and at the same time inexpensive.
  • a rubber article in particular a tire, is to be provided, on which a label can be permanently applied.
  • a label is to be provided which is suitable for being applied to a rubber article.
  • a method for printing markings on rubber articles which is characterized in that the marking is printed on, that the rubber article in the marking area has no wax and protective additives and that the printing ink has a binder which on the Rubber mixture of the labeling area is matched.
  • the method according to the invention ensures a good durability of the marking on the rubber article.
  • the fact that the printing ink has a binder which is matched to the rubber mixture of the marking area means that the color marking adheres to the rubber article intensively and thus cannot be removed.
  • the method is not limited to the use of labels with only certain simple configurations.
  • the labels to be applied can therefore be contain elements such as letters, numbers, lettering, company logos, symbols or graphic patterns.
  • the markings can be single-colored or multi-colored.
  • the rubber article has no wax and protective additives in the labeling area.
  • wax and protective additives are, for example, anti-aging agents or light protection waxes.
  • Such additives usually influence the printing properties of the tire and may lead to discoloration of the tire.
  • By eliminating such wax and protective additives possible discoloration of the rubber article and the labeling in the labeling area is avoided.
  • the rubber article printed in accordance with the invention is used in the form of tires, the printing properties of the tire are not impaired.
  • the rubber mixture of the marking area has 30 to 80 phr, preferably 40 to 70 phr, preferably 45 to 60 phr of a highly saturated rubber.
  • the unit “phr” means the amount of the respective formulation constituents, based on 100 parts by weight of rubber (parts per hundred rubber) phr of a natural rubber and / or 1 0 to 50 phr, preferably 1 5 to 40 phr, preferably 20 to 30 phr of polybutadiene.
  • the rubber mixture can 20 to 70 phr, preferably 30 to 60 phr, preferably 40 to 50 phr Soot and / or 0 to 30 phr, preferably 0 to 20 phr of a non-discoloring plasticizer.
  • the highly saturated rubber is advantageously EPDM or butyl rubber.
  • the color of the marking that is applied to the rubber article is a solvent-containing two-component color.
  • the paint advantageously has 20 to 35% color pigments and / or 2 to 5% paint auxiliaries and / or 40 to 60% solvents and / or 15 to 20% binders.
  • the binder has polyurethane resin and polyurethane prepolymer. The color is advantageously cured with aromatic and / or aliphatic isocyanates.
  • the individual components of the paint according to the invention in particular have the following advantageous properties.
  • Color pigments are those components of the color that form the desired shade.
  • the binders and paint auxiliaries are responsible for the adhesion of the ink to the printing surface and the mechanical properties of the resulting ink film.
  • the solvents serve to keep the remaining components of the paint in a sufficiently liquid form so that the paint can be printed on the rubber article.
  • the respective constituents of the ink according to the invention can be selected and combined depending on the material of the rubber article to be printed and the required properties of the print.
  • the color of the marking is applied to the rubber article with a layer thickness of 10 to 60 ⁇ m, preferably 15 to 30 ⁇ m.
  • the markings are applied to the rubber article by a tampon printing method.
  • This printing process which is described in more detail below, is characterized by its simple handling. With the help of the tampon printing process it is therefore possible to apply the markings to a corresponding rubber article in a simple and cost-effective manner.
  • colors can be printed one after the other and without intermediate drying. It is therefore possible with the aid of this method to apply monochrome or multicolor markings to the rubber article.
  • a tire is created in which a marking can be applied in particular by the method according to the invention.
  • the tire has no wax or protective additives in the marking area. This ensures that the tire's grip is not affected. This is particularly important because the usual marking areas for tires can be on the sidewall and / or on / in the profile of the tire. Furthermore, discoloration of the tire or the marking in the marking area is avoided by omitting wax or protective additives.
  • the tire can have a non-discoloring rubber mixture in the marking area.
  • a discoloring rubber mixture can be used instead of the non-discoloring rubber mixture.
  • the discoloring rubber mixture must also be coated with a suitable barrier mixture.
  • This barrier mixture can consist of butyl, for example.
  • the barrier mixture must have a suitable thickness. Such a thickness is preferably 0.5 mm.
  • the tire has a mixture in the marking area which corresponds to the mixture of the rubber article to be printed described above.
  • the mixture of the tire according to the invention forms a good basis for permanently applying a marking to the tire.
  • a marking is created which can be applied to a rubber article in particular by a method according to the invention.
  • the rubber article can be, for example, a tire according to the invention.
  • the marking according to the invention consists of egg ⁇ ner color or multiple colors and is characterized in that the color or colors comprising a binder / have, which is tuned to the rubber mixture in the characterizing portion of the rubber article from ⁇ .
  • the color is advantageously a solvent-containing two-component color.
  • the paint according to the invention has the constituents and compositions described above with regard to the process according to the invention.
  • the color is advantageously curable by means of aromatic and / or aliphatic isocyanates.
  • the marking according to the invention has a layer thickness of 10 to 60 ⁇ m, preferably 15 to 30 ⁇ m.
  • FIG. 1 shows a side view of a rubber article designed as a tire, on which an identification according to the invention has been applied using the method according to the invention.
  • the reference numeral 10 denotes a tire, in the identification area 20 of which an identification 30 has been applied.
  • the marking area 20 of the tire 10 is the side wall thereof.
  • the marking 30 has the shape of a lettering.
  • the marking area 20 of the tire 10 consists of a non-discoloring mixture of components with the following composition: 50 phr of highly saturated rubber, 40 phr of natural rubber, 10 phr of polybutadiene, 50 phr of carbon black and 12 phr of non-discoloring plasticizer .
  • the mixture is further characterized in that it contains no anti-aging agents and / or light protection waxes.
  • the marking 30, which consists of a solvent-containing two-component ink according to the invention, is printed on the side wall 20 of the tire 10.
  • the tampon printing process works as follows:
  • a cliché is produced on which the marking to be used is available as a recess. These depressions can be produced, for example, by exposure of a light-sensitive layer and a subsequent etching process.
  • the light-sensitive layer is advantageously applied to a base plate.
  • the base plate can be made of metal or plastic, for example.
  • the cliché is flooded with color.
  • the ink is removed from the cliché by means of a pull-off device in such a way that a color film remains only in the depressions. This remaining color film is picked up by a stamp called a tompon.
  • Such tampons are preferably made of different silicone rubbers.
  • the ink is absorbed from the cliché onto the tampon by unrolling the tampon on the cliché. This transfers the color from the depressions in the cliché to the tampon.
  • the label, which is now formed on the tampon, is then transferred to the side wall of the tire to be printed. This transfer in turn takes place in that the tampon is rolled off on the side wall of the tire.
  • Solvent-based printing inks are advantageously used to carry out the tampon printing process.
  • the reason for this arises from the fact that the open surface of this color becomes sticky by evaporation of the solvent. In this way, good ink adhesion is achieved both on the tampon and subsequently on the side wall of the tire.
  • the printing sequence of the process can be set by using colors with different solvent contents.
  • the use of the tampon printing method described above provides an easy to carry out and inexpensive method with which markings can be printed on rubber articles.
  • the tampon printing process has the advantage that labels of any configuration can be printed on the rubber articles.
  • the special printing process and the composition of the rubber material and the color according to the invention create a good adhesive connection between the marking and the rubber material.
