Method of protection and reduction of the corroded metallic surfaces The invention is pertaining to the method of protection and recovery of the corroded metallic surfaces working in conditions of the abrasive wear, action of the aggressive mediums, for example, at transportation of the fertilizers, in the heat and power industry, chemical industry and the extractive industry at the repairs of the rust through equipment. The method provides, that at first they apply on the metallic surface of the priming coating based on the composition containing the following components (in mass. %): 20.0-30.0 - the epoxy dian resin with the epoxy reacting weight of 450-500, the curing agent, 12.0-25.0 - pigments, 12.0-25.0 - fillers, 20.0-30.0 - polyamide curing agent Versamid 115, the rest - organic solvents, with the subsequent drying "up to detachment". After that they apply the second insulating layer having the following composition (in mass %): 20.0-35.0 - of the epoxy dian resin with the epoxy reacting weight of 450-500, 5.0-10.0 - pigments, 5.0-12.0 -fillers, 20.0-35.0 - polyamide curing agents Versamid 115, 10.0-30.0 - micaceous iron oxides, the rest - the organic dissolvents, with the subsequent "up to detachment". After that they apply the third outer layer from the composition containing the following components (in mass %): 20.0-40.0 - the acrylic or polyester hydroxyl-containing resin used as the binder, 10.0-20.0 - pigments, 5.0-10.0 - fillers, 11.0-22.0 - the curing agent - aliphatic polyisocyanate, 0.1-0.5 - the organically modified polysiloxane, the rest - the organic solvents, further the product is dried up to the complete solidification. The invention allows to increase the corrosion resistance of the coating. |

Invention relates to preparing epoxy-woody composition. The composition comprises the following content of components, mas. p. p.: epoxy-diane resin ED-20, 100; polyethylenepolyamine as an amine hardening agent, 10; plasticizing agent, 15; rubber crumbs as waste in rubber-technical manufacture, 125, and pone saw-dust as filling agents, 62.5. As a plasticizer agent the invention uses mother epoxy resin representing waste in manufacture of epoxy resins. Invention provides enhancing water-resisting properties and to obtain the composition preventing evolving free phenol from splint-slab plate and possessing high exploitation properties. Invention is used as a water-resistant cover for woody plates and splint-slab plates and for reconstruction of defected member sites of woody constructions. |
