COMPOSITION FOR PROTECTIVE COVER Russian patent published in 2006 - IPC C09D5/08 C09D163/02 C09D109/02 C09D175/04 

FIELD: anticorrosive materials.

SUBSTANCE: invention relates to a method for preparing compositions designated for protecting constructions made of aluminum alloys, different steels and polymeric composition materials including carbon plastics against effect of environment (moisture, erosion, dynamic loading) at temperature exploitation from -60°C to +150°C. The composition comprises the following ratio of components, mas. p. p.: a binding agent, 100.0; a hardening agent of amine type, 15.0-50.0; a modifying agent, 3.0-50.0; a filling agent, 7.0-50.0; an organic solvent, 140.0-400.0. As a binding agent the composition comprises epoxy diane resin or a mixture of epoxy diane resins of molecular mass 1000-3500 Da. As a modifying agent the composition comprises low-molecular epoxy urethane or butadiene acrylonitrile carboxylate rubber. As a filling agent the composition comprises zinc oxide or boron oxide thread-like crystals. Additionally, the composition can comprise pigments and corrosion inhibitors. Invention provides enhancing water resistance and resistance against dynamic loading and effect of rapid air flow containing sand particles and rain drops.

EFFECT: improved and valuable technical properties of composition.
