发明名称 Isocyanate group containing adducts and compositions having good adhesion on coated substrates
摘要 Isocyanate group containing adduct compound (I), is new. Isocyanate group containing adduct compound of formula ((OCN) 2Y 1>NHC(O)XR 1>), is new. R 1>1-20C hydrocarbon optionally containing 0-2 heteroatoms, and does not contain silane groups; X : -O-, -S-, -N(R 2>)-, -N(R 2>)-CO-, -N(R 3>)-CO-N(R 4>)- or -O-CO-; R 2>1-20C hydrocarbon remainder with 1 to 20 C atoms, which optionally shows a cyclic part and at least a functional group such as ether, sulfone, nitrile, nitro, carbonic acid ester, sulfonic acid ester or phosphonic acid ester; either R 3>, R 4>1-20C hydrocarbon, which optionally shows a cyclic part; or R 3>R 4>+urea material : 5-6 membered ring, which is optionally substituted and shows 3-20 C atoms; and Y 1>an oligomer aliphatic polyisocyanate with three isocyanate group after separating all isocyanate group. Independent claims are included for: (1) the preparation of (I); (2) a single-component composition comprising (I), at least a isocyanate group containing polymer and optionally silane group; (3) a two-component composition comprising (I) and at least a polyisocyanate as component 1, and polyol and/or at least a polyamine as component 2; (4) a mixed two-component composition, obtained by mixing the two components, so that: the isocyanate groups are used in excess with respect to the hydroxyl- and/or amino group, preferably the ratio of hydroxyl and amino to isocyanate is 0.5-0.95; (5) the preparation of the single-component composition comprising preparing (I) and the polymer and separating (I) from polymer; (6) the preparation of two-component composition comprising mixing polyisocyanate with (I); (7) a agglutinating process comprising applying the single-component composition or the mixed two-component composition on a substrate (S1) and/or a substrate (S2), joining the adherend, and hardening the composition, where S1 and S2 are same or different; (8) a sealing procedure comprising applying the single-component composition or the mixed two-component composition on S1 and/or S2, and hardening the composition; and (9) a pasted or sealed articles obtained by the process.
