摘要： This invention relates to a novel polyaldimine, preparation process of the polyaldimine, moisture curable polyurethane composition containing the polyaldimine and use of the composition.
Polyaldimine of this invention is represented by the formula (I):
wherein R¹, R² and R³ are a halogen atom, hydrogen atom, alkoxy group having 4 or less carbon atoms or an alkyl group having 5 or less carbon atoms, and may be the same or different; R⁴ is a hydrogen atom or a methyl group; Y is -N=CH-C(R⁵ )₃ or -N=CH-C(CH₃ )₂-CH₂-O-CO-R⁶ wherein R⁵ is an alkyl group having 4 or less carbon atoms, R⁶ is an alkyl group, anilino group, benzylamino group or an alkylamino group having 16 or less carbon atoms; and ℓ is an integer of 1 or 2, m is an integer of 1 to 3, and n is an integer of 0 to 300.
Polyaldimine is prepared by condensation of the corresponding aromatic polyamine and aldehyde.
A moisture curable polyurethane composition is prepared from the above polyaldimine and organic polyisocyanates. Sealing materials, wall covering materials, water proof materials and flooring materials can be prepared by blending thixotropic agents or fillers with the polyurethane composition. These materials have very good storage stability and are rapidly cured by atmospheric moisture and cured polyurethane resin having excellent properties can be obtained.摘要翻译： 本发明涉及一种新型聚醛亚胺，聚醛亚胺的制备方法，含有该聚醛亚胺的湿固化聚氨酯组合物以及该组合物的用途。 本发明的聚醛亚胺由式（Ⅰ）表示：其中R 1，R 2和R 3是卤素原子，氢原子，具有4个或更少碳原子的烷氧基或具有5个或更少碳原子的烷基，并且可以是 相同或不同; R 4是氢原子或甲基; Y是-N = CH-C（R 5）3或-N = CH-C（CH 3）2 -CH 2 -O-CO-R 6，其中R 5是具有4个或更少碳原子的烷基，R 7是烷基， 苯胺基，苄氨基或具有16个或更少碳原子的烷基氨基; l是1或2的整数，m是1至3的整数，n是0至300的整数。聚醛亚胺通过相应的芳族多胺和醛的缩合制备。 由上述聚醛亚胺和有机多异氰酸酯制备可湿固化的聚氨酯组合物。 可通过将触变剂或填料与聚氨酯组合物混合来制备密封材料，墙壁覆盖材料，防水材料和地板材料。 这些材料具有非常好的储存稳定性并且通过大气湿度迅速固化，并且可以获得具有优异性能的固化聚氨酯树脂。
