Definitions

  • the present invention relates to retroreflective coatings, in particular intended for marking roads, a method for their realization and means for the implementation of this method.
  • This type of retroreflective coating comprises, on the surface, a layer of very small diameter glass spheres (microspheres) sprinkled on a layer of binder (paint or coating).
  • the present invention relates to a method for producing retro-reflective horizontal road markings, in which a marking product is applied to the place to be marked, characterized in that the surface of said product is dusted before drying with a mixture of treated glass microspheres for flotation and treated glass microspheres for adhesion to the marking product.
  • a practically homogeneous mixture comprising from 20 to 50%, in particular from 20 to 30%, by weight of glass microspheres treated for flotation and from 80 to 50%, in particular from 80 to 70%, weight of microspheres treated for adhesion.
  • this new type of microsphere with a certain quantity of distinct microspheres, for example water-repellent by a silicone treatment.
  • water-repellent microspheres give retroreflection results which decrease fairly quickly over time, so they are used for roadways where the marking is renewed quite frequently.
  • the water repellency treatment is tolerated because it prevents agglomeration of the microspheres and clogging of the nozzles during the application of the microspheres. This agglomeration of microspheres occurs in the hoppers of the marking machines by condensation of ambient humidity during sudden changes in atmospheric conditions.
  • mixtures preferably containing between 60 and 80% by weight, and in general approximately 75% by weight, of water-repellent microspheres.
  • percentage is too high, the advantageous characteristics of the mixtures according to the invention disappear and, when the percentage is too low, the water-repellency characteristics become much less advantageous and in particular it is no longer possible to meet French standards in matter.
  • paints and hot coatings such as alkyd, acrylic or chlorinated rubber paints, hot coatings with hydrocarbon resin or ketone resin.
  • the method according to the present invention gives particularly interesting results, in particular in terms of the durability of the retroreflection when the marking product used is a glycerophtallic paint or based on chlorinated rubber.
  • the glass microspheres used preferably have a granularity such that at least 90% by weight of said microspheres have a diameter between 0.500 and 0.125 mm.
  • the glass microspheres treated for flotation are preferably microspheres comprising a coating of a finishing agent such as a fluorocarbon agent, in particular as described in the patent of United States of America n ° 3,222,204 mentioned previously. This material must allow wetting and sinking without the meniscus normally associated with an agent improving adhesion.
  • a finishing agent such as a fluorocarbon agent
  • the glass microspheres treated for adhesion are preferably glass microspheres coated in a sufficient quantity of a coupling product which is adapted to the nature of the labeling product.
  • the coupling product can be, in particular, a silane such as 3,4-epoxycyclohexylethyltri-methoxysilane or any other chemical compound with polar surfactant groups, whose organic functions are chemically compatible with road marking products and whose inorganic functions are specific to glass silica.
  • This type of glass microspheres treated for adhesion are sold for example by the company POTTERS BALLOTINI S.A. under the name of microspheres treated with a coupling agent CP01, CP03 or CP05. This same company also supplies treated microspheres for flotation.
  • the application of the marking product on the roadways as well as the dusting of the surface with the microspheres can be carried out by any of the methods known in this field, for example the paint can be distributed by Kamber gun and the spheres atomized by Kamber gun, as for the coatings, they can be applied by a classic shoe device with smoothing plate or by projection, the spheres being distributed by gravity.
  • the dosages of the various constituents obviously depend on the type of labeling product used, the dosage in microspheres being between approximately 200 and 400 g / m 2 .
  • the present invention also relates to substantially homogeneous mixtures of microspheres intended for carrying out the process.
  • Microspheres A and B have a granularity satisfying the conditions of French approval, as well as the mixture A / B.
  • microspheres A are sold by the company POTTERS BALLOTINI S.A. under the name of microspheres treated for adhesion CP01 and microspheres B are sold by the same company under the name of microspheres treated for flotation.
  • the tests were carried out in parallel under conditions corresponding to a traffic of approximately 3,000 to 4,000 vehicles / day.
  • the first group of tests was carried out using a glycerophtallic paint distributed by Kamber gun, the spheres being distributed by gravity then atomization by Kamber gun.
  • the second group of tests is carried out under the same conditions as for Example 1, but a paint based on chlorinated rubber is used.
  • Example 1 As in Example 1, after 12 months, a much greater retroreflection is observed in the case of the A / B mixture than that observed for the traditional coatings A and B.
  • mixtures comprising 70% of water-repellent microspheres and 30% of microspheres according to the present invention can successfully undergo the water-repellency control in accordance with French standard.
