GLUING COMPOSITE Russian patent published in 2002 - IPC

FIELD: gluing composites with adhesion properties. SUBSTANCE: invention relates to fast-polymerizing gluing composites at room temperature based on 2-cyanoacrylic acid esters used in different fields of technique and in homes. As a base the gluing the composition comprises cyanoacrylate, i. e. 2-cyanoacrylic acid ester of the general formula: CH₂=C(CN)COOR¹ where R¹ means C₁-C₁₀-alkyl, and m = 2, 4, 6; CH₂CH=CH₂ CH₂C≡CH or their mixture in the ratio from 1:99 to 50:50. As modifying addition the composition comprises polymer of cyanoacrylate of the general formula: where n = 5-20; R¹ means C₁-C₁₀-alkyl, and m = 2, 4, 6; CH₂CH=CH₂ CH₂C≡CH and as stabilizing agent the composition comprises compound of the general formula: where R means and m = 2, 4, 6; CH₂C(CH₃)(X)₂ and CH₂C(C₂H₅)(X)₂ and X: in the following ratio of components, mas. p. p.: cyanoacrylate, 100; modifying addition, 0.1-10; stabilizing agent, 0.0001-0.01. EFFECT: enhanced stability and improved properties of compositions. 2 cl, 2 tbl
