Description

The invention relates to polymer composites based on fluoroplastic, the coatings of which are heat-resistant, corrosion-resistant, resistant to abrasion and can be used as non-stick in the food industry, protective - in an aggressive environment with high physical and mechanical properties on parts and equipment used in chemical , shipbuilding, aviation industry and engineering.

Known composition for non-stick coatings, baking forms, consisting of a suspension of polytetrafluoroethylene (PTFE) and ethoxylated alkyl phenol as an emulsifier applied to products in a single layer (N. Yavzina and others. "The use of fluoropolymers for non-stick coatings - Plastics", 1983 No. 3, p.13-14).

However, a single-layer coating of PTFE is porous, therefore, to obtain a coating with optimal properties, it is necessary to apply at least two layers, but the adhesion to the metal corresponds to 3-4 points (according to the lattice notch method). The lack of reliable adhesion limits the use of this coating as a facing when operating in more severe conditions, compared with baking forms, for example on kitchen utensils (pans, roasters, pie units, etc.).

A known composition for a facing coating containing a dispersion of PTFE, demineralized water, mica (coated with titanium dioxide), soot, coloring pigment (contains iron oxide, demineralized water, oleic acid, triethanolamine, butylcarbitol, toluene), a mixture containing triethanolamine toluene, butylcarbitol, the mixture additionally containing methyl methacrylate and a copolymer (40% aqueous dispersion) (UK patent No. 1557230, IPC C09D 127/18, 1976). The disadvantage of this invention is the resistance of the coating to abrasion, thermal shock (25-30 cycles of exposure to a temperature drop from + 250 ° C to + 15 ° C instead of 40-45 cycles) and thermal resistance (350-400 hours at 250 ° C in vegetable oil instead 950-1000 hours), which reduces the operational properties of the coating of the specified composition. In addition, coatings based on the well-known composition have a limited range of colors: black (mica + pigment - carbon black) or brown (mica + pigment - iron oxide), which does not satisfy the requirements for a product-decorative appearance for consumer goods .

A known composition for coating by preparing a solution in an organic solvent of an organofluorine surfactant - an epilame-perfluoroxylalkylene or perfluorinated polyalkylene oxide compound in the form of their nitrogen-containing derivatives (RU 2139902, 20.10.1999).

A known coating composition obtained by mixing polytetrafluoroethylene with a fluorine-containing oligomer, for example, Epilam or Foleox brands and a copper-containing carbon filler (RU 2278875, 06/27/2006).

A disadvantage of the known methods is that they do not provide the creation of coatings with the necessary wear resistance and protect against destruction of the surface of the product due to the lack of deep penetration of a relatively viscous composition into micropores, microcracks on the surface of the product and the binding of atomic oxygen and hydrogen. As a result of this, the surface layer of the metal is not protected from corrosion and destruction, which leads to insufficient product life. Coatings obtained by known methods can be operable at relatively low temperatures (up to 150 ° C). The method according to the patent RU 2278875, 06/27/2006 receive compositions that are used in mechanical engineering for the production of block parts and friction units of machines, but cannot be used for coatings on metal surfaces.

Known composition for primer and facing coating (patent RU No. 2170286 from 11.26.1999 "Method of coating a metal surface, composition of the primer coating and composition for facing"). Based on F-4D fluoroplastic or its mixture with F-4MDB fluoroplast (based on a tetrafluoroethylene-hexafluoropropylene copolymer) in combination with a polyamide acid varnish, aqueous paste of mica-containing fillers, carbon black, chalcogenides pre-grinded in aqueous solutions containing polyvinylpyr , emulsifier - OP-10 and water. The composition may contain iron oxides, titanium dioxide, xylene, ethyl cellosolve, monohydric alcohols, oleic acid.

Coatings based on this composition have good physicomechanical, antifriction, and non-stick properties, however, due to the uneven distribution of components in the composition system, the presence of agglomerates, the coating based on it has different thicknesses on the surface to be coated, which affects the tribological parameters, as well as resistance to loads and abrasion. In addition, this composition containing mica and pigments, such as titanium dioxide, carbon black and iron oxide, form a coating of a limited range of gray, black or brown colors, which does not satisfy consumers for their decorative appearance.

Closest to the invention in technical essence, combination of features and the achieved result is a composition for non-stick coating of pearlescent color, containing 50-65% aqueous suspension of polytetrafluoroethylene, pearlescent pigment based on muscovite mica, modified with a mixture of ethyl cellosolve, xylene, hydroxyethylated alkyl phenol and water; ethylene glycol, metal nitrate salt, saturated aliphatic alcohol and water (RU 2071493, 01/10/1997 “Composition for non-stick coating of pearlescent color”). This composition is used as a facing for application on kitchen utensils, baking dishes for bakery and confectionery products, electric ovens, etc. Coatings based on the known composition are resistant to thermal shock, resistant to boiling vegetable oil. The lamellar structure of the mica pigment has a high refractive index, which is achieved by applying a thin thin layer of metal dioxides, in particular titanium dioxide, to the mica flakes, providing a pearlescent shine. In the known composition, pearlescent pigments are silver, golden, bronze and red. The disadvantage of this composition is that only silver-colored pearlescent pigment included in its composition and coatings based on it are approved by the Ministry of Health and Social Development of the Russian Federation for contact with food, and only this composition can be used to apply products in contact with food (pans, pans, baking trays for baking bakery products, baking molds, etc.), while the color of the resulting coating is gray-pearl or black-ashy. Known pearlescent compositions of golden, bronze or red color are used for application on the outer surface of products.
