GLUING COMPOSITION Russian patent published in 2005 - IPC

FIELD: glues.

SUBSTANCE: invention relates to high-strength glues of cold hardening able to harden in the range of temperatures 10-15°C under conditions of enhanced moisture and on wetted surfaces. Invention proposes a glue composition comprising the following components, mas. p. p.: epoxydiane resin, 100; polyamide resin (product of condensation of polyethylene polyamine with higher unsaturated synthetic dicarboxylic acid methyl esters), 14-16; organosilicon amine, 1.15-1.30, and, additionally, chlorine-containing resin, 14-30; amine hardening agent, 8-22, and catalyst, 0.5-1.6. For improving the technological effectiveness the composition can comprise additionally mineral filling agent (titanium dioxide, asbestos or synthetic corundum) in the amount 5-20 mas. p. p. Prepared gluing composition can be used for repair work of glued constructions, articles and aviation technique aggregates in field conditions, and for gluing metallic and nonmetallic materials and aviation and other branches of machine engineering. Invention provides enhancing strength in shift, exfoliation and break off, enhanced water proofing, in tropic climate, possibility for hardening and retaining strength properties after hardening in the range of temperature 10-15°C under conditions of enhanced moisture and on wetted surfaces.

EFFECT: improved properties of gluing composition.
