Invention refers to processing of polymeric functional materials and can be used in machine building at coating of machine and aggregate units and units of transport systems, mainly pipes for transmission of oil products. The method for producing metal-polymeric coating consists in mixing polymer particles in a powdered form and metal containing precursor particles in a powdered form.

Polymer particles in a powdered form are selected out of a group containing polyamide, polyethylene terephthalate and polyethylene of high pressure. Particles in a powdered form of metal containing precursor represent formate or oxalate of copper, nickel, zinc or carbonyl iron. Heating, melting of polymer particles and thermolysis of precursor are carried out simultaneously in a thermo gas flow with a density of 3·106 -9·106 Wt/m2 within 10-4-10-3 sec. The mixture is settled and monolithic integration of coating is performed on the unit heated to a temperature of T=Tm+5÷40°C, where Tm is the temperature of polymer melting at the density of the gas flow of 3-5 atm.

The invention relates to epoxy compositions and can be used for protection against corrosion of machine parts and mechanisms, working in contact with corrosive environments in engineering, as well as for the protection of oil field equipment, containers, cisterns and tanks. One of the most urgent issues facing modern science, is to provide reliable corrosion protection of surfaces of machine parts and mechanisms, working in contact with corrosive environments in engineering, as well as for the protection of oil field equipment, containers, tanks and reservoirs. Therefore, these coatings must be resistant not only to oil and oil products, but also to water, have high adhesion and mechanical properties, high protective properties and not to deteriorate after prolonged exposure to operational factors. Known (patent RF №2088621) primer for anti-corrosion coatings for products made of steel and aluminum alloys of the following composition by mass:
However, this primer does not have a sufficiently high fuel and water resistance during long-term operation in liquid environments at elevated temperatures and is not combined with toplevelname sealants. The closest analogue of the claimed invention is the following composition for coating on metal (patent RF №2260610). The composition includes a polymeric binder, the modifier, the curing agent is a silicone amine, mineral filler, inhibiting pigments and an organic solvent, and as it contains a polymeric binder epoxy Dianova or amoxicillinpurchase resin as a modifier - polysulfide or carboxylated nitrile rubber, and as inhibiting pigments - strontium chromate, barium chromate, phosphate, chromium or their mixtures with abuses ratio of components parts:
As a hardener composition contains γ-aminopropyltriethoxysilane, 1 - aminohexanoate-6-aminomethylenemalonate or condensation products of γ-aminopropyltriethoxysilane. As a mineral filler composition contains barium sulfate, Aerosil, talc, titanium dioxide (rutile) or their mixtures, of a thixotropic additive are presented. As the organic solvent composition contains xylene, acetone, butyl acetate, ethyl cellosolve, or a mixture thereof. The disadvantage of the prototype is not sufficiently high resistance to the action of water (vadovaujamasi 2,16-2,53% after 3000 hours of testing), which complicates the application of the above composition with prolonged exposure, for example, produced water tanks for storage of oil and oil products. The technical object of the present invention is to increase the protective properties of the composition for coating on metal. The specified technical task is solved by the fact that SOS is AB for coating metal, including polymeric binder is epoxy Dianova resin modifier, the curing agent is a silicone amine - γ-aminopropyltriethoxysilane, mineral filler is titanium dioxide (rutile), which inhibits pigment - chromium phosphate, an organic solvent, xylene, acetone, butyl acetate, ethyl cellosolve, characterized in that as a modifier composition contains apoximately oligomer, optionally thixotropic additive - Aerosil and anti-corrosion additive is zinc metal in the following ratio, parts by weight:
As the polymeric binder in the present invention is used Dianova epoxy resin e-41 on THE other 6-10-607-78 or e-40 on THE 6-10-971-75. Used as a modifier apoximately oligomer PEF (TU 103466-80)affects the parameter acidity of the surface h is of fillers and the number of functional groups on the phase boundary, determining the adhesion of film-forming substance to the filler particles and the coating to the metal substrate. Organosilicon amine - γ-aminopropyltriethoxysilane on THE 6-02-724-77 used as a hardener in the proposed structure, interacts with the polymeric binder, and has a catalytic effect on the process of interaction between epoxy groups of the polymeric binder with functional groups of the modifier (primary amines). The specified curing agent performs the role of "amplifier" adhesion, since this ratio with the polymer binder and modifier is a chemical bond between the coating and substrate due to the interaction of apachegroup with hydrated oxidized surface metals. The use of rutile grade R-04 (GOST 9808-75) as filler due to its chemical inertness for active interaction with film-forming agents and modifiers contributing to the increase of protective properties, in particular, water-resistant coating. Aerosil grades a-300 (GOST 14922-77) is introduced into the paint composition as a thixotropic additive, allowing you to keep the freshly applied coating on vertical and inclined surfaces. Introduction to composition for coating leachate chromium (inhibiting by the pigment as tattoo is) significantly increases the protective properties of the proposed structure. When exposed to a corrosive environment chromates, having slight solubility in water, creating artificial conditions for passivation of metal, displacing electrode potential in the positive direction, and inhibit electrochemical processes of metal corrosion. The application of phosphate of chromium on THE 6-18-87-85 allows you to adjust the rate of leaching in the initial and final stage. The presence of zinc powder brand PC-6 (GOST 12601-76) provides cathodic protection to the metal during aging of the coating and the appearance of a defect. As the organic solvent composition contains xylene, acetone, butyl acetate, ethyl cellosolve. This composition allows to obtain petroleum-and water-resistant coating with high adhesion and physical-mechanical properties, barrier properties, providing long-term protection of steel structures, which are used in water and other liquid corrosive environments. The embodiments of the invention are shown in tables 1,2.
Technology of preparation of the composition (examples 1-8) consists in the following. Polymer binder dissolved in a mixture of solvents. To the resulting solution add modifiers, pigments and fillers and pounded to a milling degree of 25-35 microns ("wedge"). Before use in the compo is iciu enter hardener, mix and bring to a viscosity 13-16 with the viscometer B3-4. The coating was obtained by brush application on steel (St3) peskostrujnymi samples in 2 layers with a total thickness of 180 mm, the Duration of curing of each layer was 24 h Exposure of the samples coated with coating before placing them in a corrosive environment was 8-10 days. As can be seen from table 2, the adhesion strength of the proposed structure to the steel and the swelling properties of the fuel are at the level of the prototype, and the swelling properties in water decreased to 0.79-2,10 against 2,16-2,53 that of the prototype. Composition for coating metal, comprising a polymeric binder epoxy Dianova resin modifier, the curing agent is a silicone amine - γ-aminopropyltriethoxysilane, mineral filler is titanium dioxide (rutile), which inhibits pigment - chromium phosphate, an organic solvent is xylene, acetone, butyl acetate, ethyl cellosolve, characterized in that as a modifier composition contains apoximately oligomer, optionally thixotropic additive - Aerosil and anti-corrosion additive is zinc metal in the following ratio of components, parts by weight:
