The invention relates to the field of polymer compositions based on epoxy resins which can be used to protect metal structures from corrosion, erosion and corrosion-erosion wear. One of the pressing issues facing modern science, is to protect metal structures from the corrosive and erosive effects of the external environment, resulting in the destruction of the surface layers of the metal and eventually the whole structure. Known anticorrosive composition for protection of metal structures, equipment and facilities described in U.S. Pat. RU # 2174136 (CL. 09D 5/08, 163/02, 2001). This composition contains a binder is epoxy resin, modifier - Thiokol mark 1, hardener - ASOT-2 and the filler - fine-flaked alpha iron oxide. The coatings obtained from this composition are durable (15) and wear under the action of chemicals, moisture, temperatures exceeding 100°C. However, in addition to the above advantages of these coatings have significant drawbacks. For example, in the presence of alpha-iron oxide at elevated temperatures increases the decomposition rate of polar bonds in the polymer, which leads to a sharp deterioration of physical and mechanical properties of coatings in which the process of their operation, the lack of elasticity and water resistance, especially in hot water. The latter requirement is especially important in the protection of large hydraulic structures, as well as tank farms, where periodically for washing using hot water or water vapor. Another significant disadvantage of known composition is its low thixotropy. The closest to the technical nature of the claimed composition is the composition given in the description of the invention RU # 2261879 (CL. 09D 5/08, 163/02, 10.10.2005), comprising a binder epoxy Dianova resin, modifier - butadiene-nitrile low molecular weight rubber or polysulfide rubber, or acrylic resin, crasneanscki amine curing agent in combination with polyethylenepolyamine, scaly filler - scaled silicon, representing a departure from the production of ground crystalline silicon for the production of organosilicon compounds and fine aggregate are presented and/or micro-talc in the following ratio, parts by weight:
This coating has high adhesion to metals and concrete, high mechanical strength, elasticity, wear resistance, weather resistance, resistance to hot water, durability. The disadvantages of the prototype, in our opinion, should include: 1) the need for the use as a component of production waste ground silicon, which creates difficulties in purchasing in individual regions, as well as in obtaining the relevant certificate of conformity; 2) use as a modifier of butadiene-nitrile or polysulfide rubber, or acrylic resin does not provide sufficient chemical resistance in nefteproducttehnika environments; 3) thickness of the resulting coating at least 100-120 μm, the authors noted as an advantage. At the same time for the protection of process equipment, piping, steel structures, many objects of oil and gas, chemical, food and other industries significant thickness unacceptable due to the high occurrence of internal stresses, leading to the formation of defects in the coating and reduce the protective capability. The basis of the invention is to create a polymer composition for protecting metal structures, pozvolyauschaya floor, combining the advantages of the known coatings, thus completely consisting of commercially manufactured components, has high water, and gasoline, which allows to obtain layers with a thickness of 30-40 μm. This object is achieved in that the proposed composition comprising a binder epoxy Dianova resin ED-20, modifier, hardener, fine-grained filler Aerosil, advanced antifriction filler is a mixture of graphite and molybdenum disulfide in their mass ratio of 4:1 (wt.) and a solvent to a viscosity, according to the invention as a modifier, it contains a resin oxilan-5 or oxilan-6, as a hardener - aminophenolic curing agent, the solvent is acetone or a solvent R-4, or solvent No. 646. The claimed composition contains these components in the following ratio, parts by weight:
Use as the modifier resin oxilan-5 or oxilan-6, representing globalising aliphatic trifunctional epoxy resin with an epoxy number of 6-8%, contributes to the reduction of internal stresses, increase plasticity, bezopasnosti. As a hardener is applied aminophenolic hardener Agidol-51, or Agidol-52, or AF-2, allows to apply the coating at lower temperatures and on wet surfaces. Hardeners Agidol are mixtures of phenolic bases of manniche: 2-N,N'-dimethylaminomethylphenol (o-Agidol-51), 4-N,N'-dimethylaminomethylphenol (p-Agidol-51), 2,6-di-N,N'-dimethylaminomethylphenol (o-Agidol-52), 2,4-di-N,N'-dimethylaminomethylphenol (p-Agidol-52), issued by THE 38.103.356-96. Hardener AF-2 produced according to TU 6-05-1663-79. Aerosil helps keep uncured coatings on vertical and inclined surfaces of protected structures. The amount of solvent (parts by weight) depends on the method of coating application: by brush - 8-12, spray air - 16-20, airless - 12-15. In addition, the claimed composition to impart color and improve the appearance may be added pigments, such as white (titanium dioxide grades R-02, R-03, R-04, GOST 9808-75), olive green (chromium oxide pigment varieties OHP-1, KP-2 according to GOST 2912-73), purple-red (red lead lead grades M-1, M-2 and M-3 according to GOST 19151-73).
