FIELD: building industry and materials.
SUBSTANCE: 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.
EFFECT: improved and valuable technical properties of composition.
