ABRASION-RESISTANT PROTECTIVE POLYMERIC COMPOSITION Russian patent published in 2005 - IPC

FIELD: polymers.

SUBSTANCE: invention relates to a method for preparing abrasion-resistant protective polymeric composition. The composition comprises the following components, mas. p. p.: epoxydiane resin, 100; modifying agent, 30-60; organosilicon amine hardening agent, 10-20; scaly filling agent, 40-80; aerosil and/or microtalc, 10-20 as a finely divided filling agent. Resins ED-18, ED-20 and E-41 are used as epoxydiane resin. Low-molecular butadiene-nitrile rubber or polysulfide rubber, or acrylic resin is used as a modifying agent. Organosilicon amine hardening agent represents aminosilane or aminosiloxane that is used in common with polyethylene polyamine in their mass ratio = 1:1. The condensation product of polyethylene polyamine with trimerized fatty acid from flax or tall oil can be added to the hardening agent composition. Scaly silicon representing waste in manufacture of crystalline silicon for preparing organosilicon compounds is used as a scaly filling agent. Pigments can be added to the composition for coloring. Invention provides preparing the composition showing high adhesion to metals, for example, to steel and to concrete, high mechanical strength, elasticity, abrasion-resistance, atmosphere-resistance, resistance to hot water effect and longevity. Proposed polymeric composition can be used for protection of metallic and concrete constructions, for floor covering and so on.

EFFECT: improved and valuable properties of composition.
