FIELD: chemistry. ^ SUBSTANCE: invention relates to preparation of epoxide compositions meant for adhesive, priming, sealing and repair cold setting mixtures. Described is an epoxide composition containing the following (pts. wt): epoxide diane resin -100, low-molecular rubber - urethane prepolymer SKU-PFL-100 with weight fraction of isocyanate groups in the range of 5.3-6.4 % - 3.5-15, plasticiser - EDOS which is a mixture of dioxane alcohols and their high-boiling esters - 1.2-8.0, carbon nanomaterial - fullerenes C2n, where n is not less than 30, or their mixture - 0.15-1.25, polyethylene polyamine hardener 13.5-26.5. ^ EFFECT: epoxide composition provides good, stable physical and mechanical, adhesion and processing properties with a short preparation process at room temperature. ^ 1 cl, 2 tbl, 4 ex |
