Definitions
- the invention relates to a method for producing a product with an easily cleanable surface by coating the surface with a hydrophobic material, and to the products obtainable by the method.
- the equipping of objects with dirt-repellent substances is generally known.
- the usual procedure is to hydrophobize the surface of the objects to be treated by applying a liquid composition.
- a large number of chemicals are usually used for this, but in particular silicone oils and / or fluorinated silanes.
- the surfaces treated in this way prove to be difficult to wet, causing the water to roll off. Dirt adheres only weakly to the treated surface and is therefore easy to remove.
- EP-A-0, 658, 525 describes the production of a water-repellent multilayer film.
- Three different target solutions are prepared, mixed, applied to a glass substrate and a gel coating is created on the glass surface.
- a metal oxide surface layer is then produced by heating.
- a fluoroalkylsilane layer is then applied to this metal oxide layer, as described above.
- JP-A-11 092 175 describes a process according to which methoxysilane or an ethoxysilane compound containing a fluorocarbon chain is fixed on the surface of small particles with a diameter of 100 nm.
- the particles modified in this way are then dissolved in an aqueous medium and applied to a surface to be coated, the solvent is removed and the residue is then baked. In this way a surface coated with small hydrophobized particles is obtained.
- WO 99/64363 describes the production of a water-repellent surface, the surface of the glass first being roughened and all metal ions present on the surface being removed. A water-repellent film is then applied to the previously treated surface in a manner known per se. By roughening the surface, the roughness valleys thus obtained are filled with the hydrophobicizing agent.
- WO 99/02463 describes the production of a scratch-resistant coating in which an organic substance with silicone-like networks is applied to the surface. Subsequently, a heat treatment is carried out at which the temperature and duration are selected such that the applied, purely organic layer is largely decomposed and / or removed, but a connection of inorganic molecules of the carrier material and organic molecules of the applied substance can form in the uppermost molecular layers. In this way, an organic substance, such as a methyl group, is bonded directly to the silicon atom of the glass surface, forming an Si-C bond.
- the aim of the invention is therefore to provide an easy-care object whose easy-care and dirt-repellent finish remains permanently and which is also abrasion-resistant under stress, as a result of which the aforementioned easy-care properties on the object or product are retained for a long time.
- Another object of the invention is to provide such equipment for optical elements which does not change the optical properties of the element or does not noticeably change it.
- a uniform, resistant coating or a coating on a product with homogeneous properties in cross section can be achieved by providing its surface with a layer which comprises a thin metal oxide network or a metal oxide matrix, in the network a hydrophobic substance is evenly distributed.
- the layer is usually a uniform layer made of a coherent sheet-like metal oxide network.
- the metal oxide networks according to the invention can have open or closed pores.
- the metal oxide layers according to the invention are formed by thermal treatment of an applied gel layer and remain on the product as a solid coating or coating.
- the hydrophobic substance is present in the coating according to the invention in an evenly distributed manner, that is to say from the layer side adhering to the carrier material to the outer layer surface over the cross section in a homogeneous concentration and does not accumulate, exclusively or mainly on the outer coating surface.
- the surface layer retains the properties desired according to the invention even in the case of surface abrasion.
- the gels used according to the invention are in particular metal oxide gels which can be produced by means of a sol-gel process.
- the gels are formed in situ during application to the object or product to be coated, as a result of which a uniform, continuous gel network is generated on the surface of the object to be coated.

- Preferred gels are hydrogels, alkogels, xerogels and / or aerogels.
- the inventive addition of the hydrophobic, possibly also oleophobic, substance to the sol mixture before or during the formation of the gel has the effect that the hydrophobic substance is contained in an evenly distributed manner in the entire volume of the gel network being formed and is chemically bound, for example, by its silanol groups by polycondensation , In this way it is possible to impart particularly abrasion-resistant and permanent dirt-repellent properties to the surface treated in this way.
- the general production of gel layers by means of a sol-gel process is known per se and has been described in many different ways.
- the usual procedure is that in a solution, preferably a water-containing and / or alcoholic solution, with inorganic metal salts or organometallic compounds such as metal alkoxides, a polymer reaction is produced by hydrolysis, a colloidal suspension, ie a sol, being formed.
- a continuous gel network is formed from the sol by further hydrolysis.

- the final formation of the entire gel network is preferably accelerated by heating. Typical temperatures for this are between 0 ° C. and 200 ° C., preferably between 20 ° C.

- the coating mixture therefore also contains viscosity modifiers such as PVP, PVA and PEO.
- Layer thicknesses which can preferably be produced according to the invention are between 0.5 nm and 1 ⁇ m, layer thicknesses of ⁇ 200 nm being preferred.
- the layer is preferably dried at room temperature for at least 1 minute, preferably at least 3 minutes, and then cured at elevated temperature, any substances added, such as the viscosity modifiers, being pyrolyzed or burned.
