Definitions
- the invention relates to a non-stick coating with significantly improved abrasion resistance.
- Organic fluoropolymer coatings show very good non-stick properties due to their low surface energy and high temperature and chemical resistance due to the high C-F bond energies.
- non-stick coatings for kitchen appliances such coatings are widely used.
- the low hardness of the fluoropolymers used in these coatings means that these coatings are not very resistant to damage.
- the adhesion of the layers following the base layer depends on the content of thermoplastic fluoropolymers present in the interface between the base layer and the subsequent layer. This is due to the fact that the adhesion between the base layer and subsequent layer is achieved by the fluoropolymers in the base layer during the firing process with the fluoropolymers of the next layer merge.
- An advantage with respect to adhesion to the substrate is a gradient of fluoropolymers with as few fluoropolymers as possible in the interface between the substrate and the base layer and as many fluoropolymers as possible in the interface between the base layer and the subsequent layer.
- PAI Polyamide-imides
- hard inorganic fillers have been used in addition to the aforementioned improvement in adhesion to the substrate.
- EP 1016466 A2 describes a multi-layer ceramic reinforced non-stick coating in which the base layer contains ceramic particles, but which are so large that they protrude from the cover layer and thereby keep the abrasive stress of the cover layer.
- US 6,761,964 describes a multilayer non-stick coating comprising a base layer of fluoropolymers, primer polymers and large inorganic filler particles anchored in the base layer and projecting into the subsequent intermediate layer consisting of fluoropolymers and smaller ceramic filler particles and a cover layer consisting exclusively of fluoropolymers ,
- a further possibility to improve the mechanical properties of non-stick coatings is the adhesion-promoting, relatively brittle polymer polyamide-imide (PAI) (elongation at break approx. 8%) at least partially against the more viscous, linear aromatic, partially crystalline polyetheretherketone (PEEK, FIG. 2 ) (Breaking elongation approx. 50%).
- PAI polymer polyamide-imide
- the coatings are less brittle and a force on the coating leads less quickly to breakage.
- US 6,596,380 describes, for example, a multilayer coating which has a base layer consisting of min. 50% PEEK adhesion promoting polymers selected from polyamideimide (PAI), polyphenylene sulphide (PPS), polyetherimide (PEI) or polyimide (PI) and inert inorganic fillers, followed by an intermediate layer consisting of organic fluoropolymers and a topcoat of organic fluoropolymers.
- PES polyphenylene sulphide
- PEI polyetherimide
- PI polyimide
- WO 00/54895 a non-stick coating with improved scratch resistance with a base layer applied to a substrate consisting exclusively of polyetheretherketone (PEEK), which is characterized by one or more several cover layers which includes a fluoroplastic is covered.
- the layer following the polyetheretherketone layer is an adhesion-promoting polyamideimide-containing layer.
- the base layer is first melted at at least 340 ° C and cooled again, then the adhesion-promoting intermediate layer consisting of polyamide-imide (PAI) and PTFE and the possibly following outer layers is applied and baked the entire assembly at 400 to 420 ° C.
- PAI polyamide-imide
- DE 10 2005 004828 A1 describes a multilayer coating whose base layer comprises one or more high-performance polymers selected from polyaryl ether ketones (PEEK or PEK), liquid crystal polymers (LCP), polyphenylene sulfide (PPS) or mixtures thereof and the final covering layer of a high-performance thermoplastic selected from polyaryl ether ketones (PEEK or PEK), liquid crystal polymers ( LCP), polyphenylene sulfide (PPS) and 20-30% thermoplastic fluoropolymers.
- a high-performance thermoplastic selected from polyaryl ether ketones (PEEK or PEK), liquid crystal polymers ( LCP), polyphenylene sulfide (PPS) and 20-30% thermoplastic fluoropolymers.
- hard inorganic fillers may be contained in the layers lying below the top layer whose d 50 value of the particle size must be at most twice as large as the layer thickness of the finished baked layer.
- US 5,536,583 describes an article comprising as a base layer a polyether resin layer and at least one cover layer consisting of a fluoropolymer resin and an additive such as polyphenylene sulfide (PPS) or inorganic crystalline powders.
- PPS polyphenylene sulfide
- fluoropolymers there have been used tetrafluoroethylene-perfluoro (alkyloxyvinyl ether) copolymer (PFA), poly (vinylidene fluoride) (PVDF), ethylene-chlorotrifluoroethylene copolymer (E-CTFE), ethylene-tetrafluoroethylene copolymer (E-TFE), perfluoroethylene-propylene copolymer (FEP) and poly (chlorotrifluoroethylene) (CTFE) or mixtures thereof, but not polytetrafluoroethylene (PTFE).
- PFA tetrafluoroethylene-perfluoro (alkyloxyvinyl ether) copolymer
- PVDF poly (vinylidene fluoride)
- E-CTFE ethylene-chlorotrifluoroethylene copolymer
- E-TFE ethylene-tetrafluoroethylene copolymer
- FEP perfluoroethylene-propylene copo
- PTFE has the highest non-stick effect among fluoropolymers. Due to its high melt viscosity above the crystallite melting range, PTFE is not easy to melt but only sinters at the grain boundaries. This makes it difficult to formulate a cover layer for polyether resin layers with PTFE contents> 30%. Topcoats with high PTFE contents have so far shown no sufficient adhesion to the underlying layer without the use of adhesion promoter layers.
- An object of the present invention is to propose an improved non-stick coating for an article over the prior art.
- the object of the invention is achieved by the non-stick coating according to claim 1.
- This non-stick coating has at least three layers, with a cover layer having a dry film thickness of 10 to 50 .mu.m, preferably 20 and 30 .mu.m, an intermediate layer having a dry film thickness of 10 to 100 .mu.m, preferably 20 and 30 .mu.m, and a base layer with a Dry film thickness of 10 to 50 microns, preferably from 20 and 30 microns.

Furthermore, the topcoat contains 10% to 60% poly (oxy-1,4, phenylenecarbonyl-1,4-phenylene) (PEK).
- PEK poly (oxy-1,4, phenylenecarbonyl-1,4-phenylene)
- the intermediate layer contains 20-30% of organic thermoplastic fluoropolymers selected from copolymers of tetrafluoroethylene with perfluoroalkyl vinyl ether having 1-3 C atoms in the alkyl group, namely MFA or PFA, copolymers of tetrafluoroethylene with hexafluoropropylene (FEP) or mixtures thereof, and poly ( oxy-1,4-phenylenecarbonyl-1,4-phenylene) (PEK), as well as inorganic fillers.
- the fillers comprise particles with a size of 40 ⁇ m to 100 ⁇ m, preferably from 45 ⁇ m to 70 ⁇ m.
- the particle size is selected so that at least some of the particles protrude partially into the cover layer, but do not penetrate this cover layer.
- Copolymers of tetrafluoroethylene with perfluoroalkyl vinyl ether having 1-3 C atoms in the alkyl group (MFA or PFA)
- copolymers of tetrafluoroethylene with hexafluoropropylene (FEP) or mixtures thereof) are possible in the cover layer and thereby an improved non-stick effect without the To lose adhesion to the underlying layer or to require an additional adhesion-promoting layer of polyamide-imide (PAI) or polyphenylene sulfide (PPS).

- the cover layer 6 in this embodiment contains about 55% of organic fluoropolymers.
- the cover layer 6 contains about 35% by weight of poly (oxy-1,4-phenylenecarbonyl-1,4-phenylene) (PEK).
- the intermediate layer 4 contains about 30% of a copolymer of tetrafluoroethylene with perfluoroalkyl vinyl ether having 1-3 C atoms in the alkyl group, namely PFA and about 70% poly (oxy-1,4-phenylenecabonyl-1,4-phenylene) (PEK), as well as inorganic fillers 8.
