Definitions

  • the invention relates to a non-stick coating for a surface of a substrate containing at least one fluoropolymer and to a process for its preparation.
  • a non-stick coating is to be understood as meaning a layer structure which is such that it is particularly suitable, in particular, for rolls or other machine parts in the adhesive, rubber and / or paint-processing industry.
  • Good non-stick properties are particularly relevant where certain areas, such as labels, adhesive tapes, diapers and other products, are said to have the property of preventing adhesion of adhesive or other sticky media. This allows targeted adhesive areas to be created while the neighboring areas can not stick. That is, the adhesive or other sticky media can be applied by machine targeted and localized.
  • the corresponding coated tools such as rolls in the paper industry for producing multilayer or laminated paper remain adhesive-free.
  • the silicone-coated surfaces in this way have no resistance to solvents and corrosion. Furthermore, these surfaces are not approved for food applications. Finally, due to the material properties of the silicone, a corresponding surface is also out of the question for some applications. In coating applications (eg in car painting) such a coated surface is unsuitable because the paint is repelled by the silicone and so it comes to the formation of so-called "fish eyes". The disadvantage is finally that the hardness of the surface is relatively low.
  • fluoroplastics for example Teflon
  • Teflon fluoroplastics
  • the fluoroplastic is sintered on a carrier layer at elevated temperatures (about 400 ° C) in order to obtain a stable composite. Due to the flow of the fluoropolymer in the course of the sintering process, however, the basic structure of the substrate is leveled; a lotus effect can not be obtained in this way.
  • EP 0 485 801 B1 discloses a heat exchanger having a plurality of plate-shaped ribs. On the fin surface is applied a mixture consisting of a silicone resin compound-containing solution and finely divided inorganic particles. Silicon is used as base layer. Furthermore, it is provided that the surface of the layer has regularly distributed micro-elevations.
  • the DE 35 44 211 A1 discloses a method of making an iron sole. As a result of the sequence of different method steps, a metallic carrier substrate is provided with a low-adhesion plastic surface which is as smooth as possible and sealed. For sealing a binder of organic type is used.
  • an article which consists of metal, ceramic, enamel or glass and which is provided with an at least single-layer coating, the inorganic and / or organic pigment, fluoropolymer and as binder resin at least one of the type of polyamide-imides, polyimides, polyetherimides and similar substances having.
  • the specification of the coating is predetermined both with regard to the amounts of the constituents and with regard to their particle size.
  • a method is known in which a layer of a plastic material is applied to a substrate with a structured surface, wherein the surface of the layer is provided with a plurality of substantially regularly distributed micro-bumps by the plastic material before application to the substrate components in an amount of 10 to 30 wt .-% and a particle size of 2 to 200 microns are added.
  • a water contact angle of 128 ° is given.
  • Substrates here and below are understood in particular to be those which at least partially consist of metal, ceramic, glass, enamel or a composite material thereof, but also those of other suitable materials. Materials are particularly suitable as part of a substrate, provided that they are sufficiently thermally stable at temperatures that occur in an optionally provided sintering process.
  • An anti-adhesive plastic is understood here and below as meaning, in particular, a fluoropolymer such as, for example, polytetrafluoroethylene (PTFE), perfluoroalkoxyalkane (PFA), perfluoroethylene-propylene copolymer (FEP), but also other suitable materials which contain perfluorinated carbon chains and have comparable hydrophobic properties.
  • a fluoropolymer such as, for example, polytetrafluoroethylene (PTFE), perfluoroalkoxyalkane (PFA), perfluoroethylene-propylene copolymer (FEP), but also other suitable materials which contain perfluorinated carbon chains and have comparable hydrophobic properties.
  • a microstructured substrate is understood here and below to mean one having a roughness in the micrometer range, in particular in the range from 2 to 50 ⁇ m Ra.
  • the substrate may be formed by the substrate itself, but also by a layer applied or applied to the substrate.
  • a hierarchical layer structure is understood to be one in which a second surface structure of a second layer is superimposed on a first layer having a first surface structure, without the first surface structure being leveled out in the process.
  • a first microstructured layer of the hierarchical layer structure is understood to be one with micro-elevations in the range of 2 to 50 ⁇ m, under a submicrostructured second layer, which overlays the first one, with elevations, in particular in a range of 0.1 to 5 ⁇ m, of which Elevations are smaller than the elevations of the first microstructured layer.
  • the first microstructured layer contains a supplement of 5 to 30 wt .-% organic and / or inorganic particles, in particular polyphenylene sulfone (PPSO 2 ) or silicon carbide (SiC) to produce an additional structuring of the layer.
  • PPSO 2 polyphenylene sulfone
  • SiC silicon carbide
  • Water contact angle of> 165 ° with a hysteresis and a drain angle, which go to 0, are possible with the non-stick coating according to the invention. This is how the pull-off force of a Tesa® - Tapes of a surface coated with the non-stick coating according to the invention go to zero.
  • the microstructured substrate is preferably produced by applying a microstructured layer to a macrostructured surface.
  • the surface of the substrate may already have a macrostructure of its own if it has a corresponding roughness.

  • At least one first microstructured layer is produced on the microstructured substrate by applying a powder containing at least one fluoropolymer having a particle size in the range from 500 nm to 30 ⁇ m, the powder preferably being heated exactly after application will cause the powder grains to melt on the ground and bond to it, but essentially retain their shape. This prevents the valleys and cavities resulting from the microstructure of the subsurface from being added by the microstructured fluoropolymer layer.
  • Fillers in the microstructured fluoropolymer layer additionally structure the microstructured layer. It is advantageous if the powder is an admixture of inorganic particles such as in particular of SiC or Al 2 SO 3 and / or organic particles such as polyamides or PPSO 2 , or mixtures thereof, preferably in a proportion of 5 to 30 wt .-%. , contains.

Also, when baking this second layer, it is advantageous if the coating is just heated so that the particles of the second layer are merely fused so that they combine with the underlying layer, but essentially retain their shape.
  • the finely dispersed fluoropolymer contains an addition of whiskers, in particular of potassium titanate whiskers, and / or of carbon nanotubes, preferably in a proportion of from 5 to 40% by weight, in particular with respect to potassium titanate whiskers preferably in a proportion of 10 to 40 wt .-%.
  • whiskers in particular of potassium titanate whiskers, and / or of carbon nanotubes, preferably in a proportion of from 5 to 40% by weight, in particular with respect to potassium titanate whiskers preferably in a proportion of 10 to 40 wt .-%.
  • a primer layer may be provided whose thickness is preferably not more than 5 ⁇ m and not less than 1 ⁇ m.
  • the hierarchical layer structure is applied to a microstructured substrate.
  • This microstructured substrate may already be present through the substrate surface, but is usually produced by a treatment and / or coating of the substrate surface, in particular by producing a hard base layer.
  • the surfaces of an aluminum body, a stainless steel body and a normal steel body after they have been degreased, first sandblasted with coarse corundum (Al 2 O 3 ). Sandblasting removed surfaces from any oxide layers and other contaminants. In addition, the surfaces have been given a first structure that allows mechanical bonding to the body surface of a subsequent coating applied by, for example, thermal spray as described below.
