Definitions
- the present invention relates to a non-stick coating having improved resistance to scratching and abrasion.
- the invention also relates to articles, and in particular cooking utensils, comprising a coating according to the invention.
- the non-stick coatings commonly used to coat cookware are made from fluorocarbon resin, such as polytetrafluoroethylene (PTFE).
- fluorocarbon resin such as polytetrafluoroethylene (PTFE).
- PTFE polytetrafluoroethylene
- these coatings are formed by the application, directly to the support, of a first bonding layer based on fluorocarbon resin, commonly called “primary layer", this first layer being covered by one or more layers of finish, also based on fluorocarbon resin.
- Such PTFE-based coatings are known for their non-stick properties but also for their chemical and thermal resistance.
- a first solution consists in forming a hard undercoat or a hard base between the support and the primary layer, said underlay forming a barrier preventing scratches from reaching the surface of the support.
- a hard undercoat may in particular be formed by a polymer, such as polyamide-imide (PAI) and / or oxy-1,4-phenylene-oxy-1,4-phenylene-carbonyl-1,4-phenylene. (PEEK), as taught by international applications WO 00/54895 and WO 00/54896 in the name of the Applicant.
- PAI polyamide-imide
- PEEK oxy-1,4-phenylene-oxy-1,4-phenylene-carbonyl-1,4-phenylene.
- a hard base can in particular be enamel, stainless steel or alumina.
- a hard base formed of alumina can be deposited on the support by thermal plasma spraying.
- this hard alumina base can also be formed directly from the support, by anodic oxidation of the latter.
- a coating comprising such a hard base, and whose resistance to scratching and abrasion is particularly satisfactory, has been described by the Applicant in its application EP 0 902 105.
- a second solution for reinforcing PTFE-based coatings consists in introducing reinforcing fillers into one of the layers forming said coatings, especially in the primary layer.
- reinforcing fillers there may be mentioned inorganic particles such as mica particles (EP 0 389 966), silica, mullite (FR 2 756 875) or metallic flakes or metallic oxides, in particular particular aluminum (EP 0 656 831).
- the average dimensions of the inorganic particles indicated by the two European documents are of the order of 5 to 200 microns.
- EP 1 016 466 describes a coating the objective of which is to deflect the abrasive forces of the external surface of the coating: for this, it comprises a primary layer based on fluorocarbon resin and which contains ceramic inorganic particles which extend beyond this primary layer, the primary layer being applied to the support and covered by one or two upper layers based on fluorocarbon resin, these upper layers covering all the ceramic particles which can extend beyond the primary layer.
- the ceramic particles present in the primary layer taught by this prior art have dimensions such that they deform the surface of the upper layers and thus ensure the formation of deflection zones on the external surface of the coating, these deflection zones allowing then deflecting the abrasion forces, thereby increasing the abrasion resistance of the coating.
- the average dimensions of the ceramic particles allowing the formation of these deflection zones are a function of the total thickness of the dry coating, according to the following relationship: the ratio of this total thickness of dry coating over the longest diameter of said ceramic particles is between 0.8 and 2.0.
- This document specifies that such particles have an average dimension of at least 14 microns ( ⁇ m), advantageously at least, 20 ⁇ m and preferably at least 25 ⁇ m.
- This prior art certainly tends to respond to the problem of producing a non-stick coating which resists scratching and abrasion but indirectly since it tends to protect the surface of the coating by deflecting the abrasion forces, and thus avoids the perforation of the coating itself.
- the external surface of the coating is then by definition deformed by the presence of the deflection zones which, over time, will be eroded under the action of friction forces, this may eventually lead to the formation of bare zones, the non-stick coating properties partially decreasing.
- the object of the present invention is therefore to provide a coating which, while retaining excellent non-stick properties, has in itself and not by a deflection effect, improved resistance to scratching and abrasion , without deformation of its external surface and without necessarily resorting to the insertion of a hard undercoat or a specific hard base, in the particular application of culinary utensils.
- the subject of the present invention is therefore a coating comprising at least one primer layer containing a fluorocarbon resin and particles inorganic, the primer being applied to a support and covered by one or more topcoats based on fluorocarbon resin.
- the inorganic particles are ceramic particles having an average diameter of less than 4 microns ( ⁇ m) and are entirely included in the primary layer, the external surface of which is therefore not deformed by their presence.
- the ceramic particles which meet the object of the present invention have a high hardness which is greater than approximately 1500 Vickers and a remarkable melting resistance, with melting points greater than 2000 ° C.
- the average diameter of the ceramic particles is between 0.01 and 3 ⁇ m approximately, advantageously between 0.05 and 2 ⁇ m approximately, more advantageously between 0.1 and 1 ⁇ m approximately, preferably of the order of 0, 5 ⁇ m approximately.
- the ceramic particles of the invention give the coating a resistance to scratching and abrasion significantly greater than that of the coatings comprising inorganic particles described by the prior art, such as mica, mullite, metallic flakes, on the one hand and / or of dimensions greater, or even much greater, recommended by the prior art, on the other hand.
- This observation is all the more surprising and unexpected as the remarkable physical and chemical properties of the ceramic particles according to the invention, in particular extreme hardness combined with a high melting point, are expressed even for extremely small dimensions.
- the ceramic particles used in the context of the present invention comprise at least one element chosen from metallic carbides, metallic nitrides, metallic borides, metallic oxycarbons, metallic oxynitrides, metallic carbonitrides and metallic oxides.
- the metal is a refractory metal, or even a mixture of refractory metals.
- a refractory metal or even a mixture of refractory metals.
- the refractory metals are chosen from titanium (Ti), zirconium (Zr), hafnium (H), tantalum (Ta), niobium (Nb), tungsten (W), molybdenum (Mo ), boron (B), beryllium (Be), silicon (Si) and aluminum (Al).
- the ceramic particles described by EP 0 543 753 have a particularly high hardness, in this case greater than 2000
- Vickers associated with an equally high density, which can be between 5 and 16 approximately.
- the ceramic particles as taught by EP 0 543 753 make it possible to better resist the impact of the "large” particles which would strike the multilayer coating according to the invention.
- the metal is at least one of the elements chosen from Ti, Zr or Hf.
- TiN, ZrN or HfN combine both the characteristics of high hardness and high melting point mentioned above with those of metals, similar in particular in terms of thermal conductivity.
- the weight proportion of ceramic particles in the primary layer is, after firing, between 1 and 40%, advantageously between 3 and 25%, preferably between
- the invention also relates to a method for producing a coating on a support, this method comprising the following steps:
- - ceramic particles are incorporated homogeneously into a composition comprising a fluorocarbon resin to form a primary layer, - at least one primary layer containing the ceramic particles is applied to the support , the primary layer forming a smooth surface,
- topcoat (s) based on fluorocarbon resin are applied to this primer layer, then
- the invention relates in particular to cooking utensils coated inside and / or outside with a non-stick coating.
- the support of these utensils can be aluminum, steel, enamelled steel, stainless steel, glass, ceramic.
- This support may or may not undergo a preliminary treatment, depending on whether one wishes to have a rough or smooth support: it can thus be treated chemically, by acid attack for example, or mechanically, in particular by sanding.
- the primary and topcoats contain a fluorocarbon resin.
- This fluorocarbon resin can be PTFE, perfluoroalkoxy (PFA) or fluorinated ethylene-propylene (FEP), or a mixture of these compounds.
- the primary and finishing layers are deposited on the support, whether or not previously treated, by spraying (spraying), by screen printing, for example in accordance with the process described in document FR 2 689 037 in the name of the Applicant, by pad printing or by roller coating.
- spraying spraying
- screen printing for example in accordance with the process described in document FR 2 689 037 in the name of the Applicant, by pad printing or by roller coating.
- Example 1 The coating of this example 1 is constituted by a primary layer applied to the support, then covered by two finishing layers, formed by an intermediate layer, itself covered by a top finishing layer.
- the composition of each of the three layers, given in parts by weight, is shown below, by way of example:
- PAI polyamide-imide
- spreading agent emulsion and film former 4-10 dispersion of fluorocarbon resin (s) (from 50 to 60% of dry extract) 15-35
- colloidal silica (30% dry extract) 10-16
- TiC powder (0.1 to 1 ⁇ m) 1-10
- dispersion of PTFE (60% dry extract) 78-90.
- emulsion of spreading agent and film-forming agent 10-20.
- the primary layer is preferably formed by a homogeneous composition of the ceramic particles with the fluorocarbon resin.
- the titanium carbide (TiC) incorporated in the primary layer is made up of a mixture of ceramic particles whose average diameter is between 0.1 and 1 micron .
- the primary layer is deposited on the support to form a smooth surface, that is to say a flat external surface, devoid of any deflection zone.
- the primary layer is then dried to obtain a primary layer whose thickness is between 4 and 16 ⁇ m; the intermediate layer is then applied, then the upper finishing layer, the assembly consisting of the intermediate and upper finishing layers having a thickness of between 10 and 25 ⁇ m. After all three layers have dried, a sintering step is carried out at 400-420 ° C of the coating thus obtained, for 3 to 7 minutes.
- a coating is obtained, on the one hand strongly adhering to the support and, on the other hand, which exhibits scratch resistance performance.
- improved tests have shown that intensive cooking of food by means of metal spatulas on a culinary utensil, in this case a pan, covered with a coating conforming to the first example above, these cooking representing one to two years conventional use of a cooking utensil, practically did not scratch the coating, compared to identical intensive cooking carried out by means of plastic spatulas, on a utensil, the primary layer of which did not contain TiC particles.
- the coating may further comprise, between the support and the primer layer, a hard undercoat.
- the coating can also include at least two primary layers, each of which contains ceramic particles having an average diameter of less than 4 microns.
- This coating is produced by depositing: - a hard undercoat devoid of fluorocarbon resin as described by WO 00/54896 or WO 00/54896, this undercoat being directly applied to the support,
- the sublayer devoid of fluorocarbon resin, is based on polyetheretherketone or oxy-1,4-phenylene-oxy-1,4-phenylene-carbonyl-1,4-phenylene (PEEK).
- the two primary layers have a composition identical to that of the primary layer of Example 1, and both contain TiC consisting of a mixture of particles whose average diameter is between 0.1 and 1 micron.
- the total thickness formed by the two primary layers is between 4 and 16 ⁇ m.
- the intermediate and upper finishing layers have respective compositions identical to those described in Example 1 above.
- the support Before the application of the PEEK-based undercoat, the support may or may not be chemically or mechanically treated, to make its surface rough.
