Definitions

  • the present invention relates to coating compositions for the production of thin self-cleaning surface coatings and processes suitable therefor, the self-cleaning preferably being carried out by exposing the surfaces to rain or moving water from time to time.
  • the self-cleaning surfaces should have an artificial surface structure of elevations and depressions, the distance between the elevations in the range of 5-200 ⁇ m and the height of the elevations in the range of 5-100 ⁇ m and at least the elevations made of hydrophobic polymers or durable hydrophobic materials exist and are not removable by water or with water or detergents.
  • appropriate surface coatings can be produced, from which water drips off and rinses off deposited particles. Due to the surface peaks of the Teflon against water, water A critical angle of over 135 ° drops, while water drops on glass have a critical angle of approximately 60 ° or on surfaces hydrophobicized with wax or grease of approximately 80-100 °.
  • the method has the disadvantage that the coating can only be applied to horizontally lying surfaces and a uniform distribution of the Teflon particles on the adhesive base and their firm connection to the base is not guaranteed. The whole process is also relatively expensive.
  • the second procedure mentioned in the patent is not economically feasible and already suffers from the problem of plasticizing Teflon.
  • hydrophobic particles together with a film-forming plastic coating agent in a suitable solvent and to apply this agent in a thin layer to the surface to be protected, a self-cleaning effect then taking place if, after the solvents have evaporated, the solvents are juxtaposed on the surface
  • Surface deposited hydrophobic plastic particles which have a diameter of approximately 10-50 ⁇ m, preferably 10-30 ⁇ m and in particular 15-25 ⁇ m, are at a certain distance from one another of approximately 5-100 ⁇ m and the layer thickness of the dry film-forming plastic is approximately 30 -60% of the average diameter of the hydrophobic plastic particles.
  • the film-forming plastic thus ensures firm adhesion between the hydrophobic plastic particles and the base and at the same time forms a waterproof covering. Because of the comparatively low cohesion between film former and hydrophobic plastic, only a very thin film of 0.5-2 ⁇ m, usually approx. 1 ⁇ m thick, remains on the top of the plastic particles. With freshly applied coatings, this thin film layer causes the entire surface to behave like the film-forming plastic itself. Aging due to atmospheric oxygen, fluctuations in temperature and humidity and, if necessary, exposure to water, however, surprisingly after a short time result in these thin film skins becoming detached and the parts of the plastic particles protruding from the film layer appearing as hydrophobic elevations and the water-repellent and self-cleaning effect trigger.
  • the plastics used for the production of paints and lacquers can be used as film-forming plastics, in particular in formulations such as those used for the production of glazes, ie particularly thin coatings. gene, are common.
  • examples include polyacrylates, polyolefins, in particular polyethylene, polyvinyl acetates and polyvinyl acetate copolymers, styrene acrylate copolymers, maleic acid copolymers, polyurethanes, alkyd resins, epoxy resins or mixtures of such substances.
  • the auxiliaries known for the production of paints and varnishes are usually added to the film formers in a customary amount.
  • examples include fillers and thickeners, matting agents, pigments, UV stabilizers and anti-microbial agents.
  • plasticizers, crosslinking agents, elasticizing agents, etc. must also be added.
  • wax has proven to be particularly advantageous for the coating of wooden surfaces, since it not only promotes the bonding of the film material to the wood, but also reduces the film hardness and thus cracks in the film layer in wood working due to temperature and moisture fluctuations largely avoided.
  • a certain amount of wax is advantageous for a rapid detachment of the thin film coatings on the polymer grains.
  • Beeswax, Camara wax or recent resins such as montan wax are equally suitable as wax.
  • the hydrophobic particles usually consist of perfluoride hydrocarbons such as Teflon or PTFE, but particles of chlorofluorocarbons or silicone particles can also be used. It is crucial for the usability of such particles that their critical angle with respect to water is over 100, preferably over 135 °, so that water drops roll off such surfaces in the sense of self-cleaning.
  • the coating composition preferably consists of 20-60% of film-forming plastics, based on the solids content, 5-50% hydrophobic powder,
  • auxiliaries 0-50% auxiliaries and on a volume part of the solids 2-10 volume parts solvent.
  • water is preferably used as the solvent, to which water-miscible organic solvents such as lower alcohols, acetone etc. may have been added.
  • the film-forming plastics are in the form of fine dispersions with particle sizes of 0.1-2 ⁇ m, wetting agents and emulsifiers bring about the necessary stabilization of the dispersion and also of the hydrophobic powders contained therein against segregation. Insofar as this is permissible from the processing location or the film-forming materials used require it, it is of course also possible to use organic solvents, for example an ester, ketone, ether, xylene or a hydrocarbon. Such solvents are known and used for the production of paints and varnishes.
  • a preferred glazing aqueous coating system based on acrylic resin has the following composition based on the solids content:
  • polyacrylate dispersion solids content of a 40-60% dispersion in water
  • elastic dispersions e.g. polyurethanes
  • 20-50 mass% solid fluorine compounds Teflon; particle size: 5-25 ⁇ m
  • Mass% matting agent sica; particle size: 5-100 ⁇ m
  • Thickener, filming aid 0.2-3 mass% liquid organic fluorine compounds
  • the above constituents are based on their volume fraction dispersed in 2-10 times the amount of water. Paraffin wax and liquid fluorine compounds, which are mixed into the film former, cause a certain hydrophobization, which causes the rainwater to roll off immediately after application of the mixture (surface critical angle approx. 100-120 °), but due to the lack of discrete hydrophobic surface structures, a self-cleaning effect in the desired Not yet enable the senses. This only occurs when the film skins covering the hydrophobic plastic particles are broken open.
  • the agents according to the invention are applied to the surfaces to be coated using the technique customary for the application of paints and paints, by brushing on, rolling on or spraying on, layer thicknesses of 30-200 .mu.m depending on the solids content. To achieve a safe covering, the application can be repeated 2 or 3 times.
  • the solvents dry, the film-forming component lies on the substrate as a uniform layer, from which the thicker plastic grains protrude as elevations. Because of the lower cohesion to the plastic, the residual layer of the film former above the plastic grains is thin (0.5-2 ⁇ m, usually approx. 1 ⁇ m).

  • FIG. 3 shows the coated surface according to FIG. 2 after aging, as a result of which the thin film layers 2 "have been removed and the upper side 3 'of the hydrophobic grains 3 protrudes from the film layer 2'.
  • the particles 3 protruding from the surface cause a very large increase in Hydrophobia, whereby water drops practically only rest on these elevations and therefore roll off easily, on the other hand that dirt particles lying between the elevations are taken away by the rolling water drops but not deposited on the surface again.
  • Aqueous acrylic dispersions according to the composition shown in the following table are applied with a brush in a thickness of 80-100 ⁇ m wet film thickness per coat to the surface of wooden panels.
  • the application is repeated twice in the same way after each drying of the previous spread.
  • a dry film layer thickness of approx. 12 ⁇ m remains, from which the larger Teflon and matting agent particles protrude by the difference between particle size and film thickness.
  • Each particle is coated with an approximately 1 ⁇ m thick film made of acrylic resin. Due to the proportion of paraffin wax and liquid fluorine compounds, the films produced in this way have a critical angle of 100-120 ° with respect to water.
  • Teflon particles are firmly embedded in the glaze means that the outstanding Teflon and matting agent particles are only released from the underlying paint film over several years by prolonged weather conditions and mechanical stresses, so that the self-cleaning effect wears off. The original effect can be restored by re-coating once with the agent according to the invention.
