Definitions
- the present invention relates to a method for the dirt-repellent finishing of surfaces, characterized in that the surfaces are coated with particles which have an average diameter of 3 nm to 5 ⁇ m and consist of a material which has a surface energy of at least 20 mN / m has and is selected from organic polymers and copolymers and inorganic solid oxides, carbonates, phosphates, silicates or sulfates from groups 3 to 14 of the periodic table.
- the coatings can be harmful or hinder the process in a variety of ways and lead to the need to repeatedly switch off and clean appropriate reactors or processing machines.
- Measuring devices encrusted with deposits can lead to incorrect and misleading results, which can lead to operating errors.
- Coverings are also disadvantageous in other applications. After wetting and evaporation, water leaves residues on surfaces, e.g. Rainwater on window panes, motor vehicles, traffic signs or billboards. Due to the wetting, flowing liquids cause friction on the surfaces to which they are exposed. This leads to friction losses, for example in ships, but also in liquids that flow through pipelines.
- wetting liquids for example emulsions, suspensions, polymer dispersions, deposits and deposits in the interior of process engineering equipment, for example pipes, boilers, tanks, reactors, heat exchangers, evaporators, condensers. pumps, nozzles, atomizers, spray dryers, crystallizers or filling systems as well as laboratory equipment.
- wetting By wetting (moistening) unwanted organisms, for example microorganisms, biofilms, algae, lichens, mosses or mussels, can grow on surfaces such as roofs, facades, shower cubicles, ships or heat exchangers.
- the deposits whose formation is to be prevented are deposits which can be caused, for example, by reactions with and on surfaces. Further reasons are the adhesion to surfaces, which can be caused by van der Waals forces, polarization effects or electrostatic double layers. Important effects are also stagnation of movement on the surface and, if necessary, reactions in the stagnant layers mentioned. Finally, there are: precipitation from solutions, evaporation residues, cracking on locally hot surfaces and microbiological activities.
- WO 96/04123 discloses self-cleaning surfaces which can be coated with polytetrafluoroethylene and which have particularly hydrophobic properties.
- the structuring is achieved by etching or embossing the surface, by physical methods
- Structured surfaces with hydrophobic properties are also known (EP-A 0 933 388), which are produced in such a way that the surface in question is etched, for example, elevations or grooves are produced on the surface at a distance of less than 10 ⁇ m and then coated with a layer of a hydrophobic polymer, for example polyvinylidene fluoride, the surface energy of the corresponding material being less than 20 mN / m.
- These layers can also contain fluorinated waxes, for example Hostaflone®.
- the surfaces modified in this way are hydrophobic and oleophobic. Wafer holders in semiconductor production are mentioned as applications, as well as the manufacture or coating of headlights, windshields or covers for solar cells.
- a disadvantage of the method, however, is that the structuring is difficult to renew after partial mechanical degradation.
- DE-A 100 22 246 discloses a coating composition which contains a finely divided powder and a binder.
- a solvent is always required to apply a binder, which is undesirable in many cases.
- the method according to the invention consists of several steps.
- the dirt-repellent surface is prepared by making it sticky before the coating step so that the particles to be applied according to the invention are fixed. This can be done through several alternative steps:
- a so-called primer can be applied, which functions as an adhesive.
- Suitable primers are, for example, polymer dispersions such as ethylene / acrylic acid copolymers which partially are quickly neutralized with ammonia or amines; a particularly preferred example is Lugalvan DC® from BASF AG; or Acronal® V 210 as a particularly preferred example of an adhesive.
- Hot melt adhesives and fusible polymers such as polyethylene, polypropylene, polystyrene, polyoctadecyl vinyl ether or polyvinyl chloride are also suitable.
- Waxes such as polyethylene waxes, polypropylene waxes, carna ⁇ ba waxes, montan waxes or paraffin waxes are also suitable as primers.
- the thickness of the adhesive layer to be applied is not critical for the method according to the invention and can be from 0.1 ⁇ m to 10 mm.
- the dirt-repellent surface in cases where the dirt-repellent surface is made of plastics, it can also be heated for a short time to a temperature that is above the glass transition temperature of the plastic in question, or partially dissolved or swollen with a solvent.
- the dirt-repellent surfaces are coated with particles that have an average diameter of 3 nm to 5 ⁇ m and that consist of a material that has a surface energy of at least 20 mN / m.
- the particles to be applied are characterized by their hydrophobic surface, their porous structure and their average diameter.
- the porous structure can best be characterized by the BET surface area, measured according to DIN 66131.
- the particles used have a BET surface area in the range from 5 to 1000 m 2 / g, preferably from 10 to 800 m 2 / g and particularly preferably from 20 to 500 m 2 / g.
- the particles consist of a material that has a surface energy of 20 mN / m or more.
- Suitable materials are organic polymers such as e.g. Polyethylene, polypropylene, polyisobutylene and polystyrene and copolymers thereof with one another or with one or more further olefins such as, for example, styrene, methyl acrylate, ethyl acrylate, methyl methacrylate, butyl acrylate, butyl methacrylate, 2-ethylhexyl acrylate, 2-ethylhexyl methacrylate, maleic anhydride or N- methylmaleimide.
- a preferred polyethylene or polypropylene is described for example in EP-A 0 761 696.
- solid inorganic oxides solid inorganic oxides, carbonates, phosphates, silicates or sulfates from groups 3 to 14 of the Periodic Table of the Elements, for example calcium oxide, silicon dioxide or aluminum oxide, calcium carbonate, calcium sulfate or calcium silicate, aluminum oxide and silicon dioxide being preferred.
- Silicon dioxide is particularly preferred in its modification tion as silica gel.
- Pyrogenic silica gels which are commercially available, for example, as Aerosil® brands from Degussa-Hüls, are very particularly preferred.
- the solid inorganic oxides can be made hydrophobic thermally by heating to 400 to 800 ° C. and preferably by physisorbed or chemisorbed organic or organometallic compounds.
- the particles are reacted before the coating step with organometallic compounds which contain at least one functional group, for example alkyl-lithium compounds such as methyl lithium, n-butyl lithium or n-hexyl lithium; or silanes such as hexamethyldisilazane, octyltrimethoxysilane, trimethylchlorosilane or dichlorodimethylsilane.
- organometallic compounds which contain at least one functional group, for example alkyl-lithium compounds such as methyl lithium, n-butyl lithium or n-hexyl lithium; or silanes such as hexamethyldisilazane, octyltrimethoxysilane, trimethylchlorosilane or dichlorodimethylsilane.
- the average diameter of the particles is in the range from 3 nm to 5 ⁇ m, preferably from 5 nm to 1 ⁇ m and particularly preferably in the range from 7 nm to 0.5 ⁇ m.
- the dirt-proof surfaces can be coated with mixtures of particles made of two or more different materials.
- the mixing ratios can be selected in a wide range, but care must be taken to ensure that the particles made of the material which has a surface energy of more than 20 mN / m are present to more than 50% by weight of the particles, preferably more than 75% by weight .-%.

- the thickness of the particle layer is particularly preferably in the range from 5 nm to 0.3 ⁇ m.
- the layer is allowed to age before the objects with the surfaces coated according to the invention are used.
- This aging can last from 20 minutes to about 10 hours, preferably 1 to 3 hours.
- the aging can be carried out at room temperature or at a slightly elevated temperature; however, the temperature should be so high that particles 10 or primers begin to sinter. It has been shown that a temperature in the range from 20 to 50 ° C. is sufficient in many cases.
- the choice of materials for the dirt-repellent 15 surfaces is not critical.
- polymers such as polyethylene, polypropylene, polystyrene, polyester, plexiglass, polyamides, polycarbonates or polyurethanes are suitable, as well as metals and alloys such as silver, palladium, platinum, steels, copper, nickel and paper, cardboard, textiles, stone, ceramics, be - 20 ton, porcelain, glass or wood.
