    • A fast curable non-isocyanate-based polyurethane- and polyurethane-epoxy network nanocomposite polymeric compositions are derived upon crosslinking a mixture comprising of natural or modified nano-clay [ionic phyllosilicate] with platelet thickness in the scale of A (˜1 nm) and aspect ratio (length/thickness) higher than 10 (nm)] preferably natural or modified montmorillonite with either a monomer(s) or oligomer(s) bearing at least one cyclocarbonate group or a mixture of the latter with an epoxy resin, with a hardener, which is a monomer or oligomer or mixtures therefrom, bearing primary and/or secondary amino groups. The use of the nanoclays reduces the gel time and increases the adhesion of the cured polyurethane and polyurethane/epoxy hybrid and also reduces its water absorption.
    • 通过将包含天然或修饰的纳米粘土[离子页硅酸盐]的混合物与A(〜1nm)的等级的血小板厚度交联,将衍生的快速可固化的非异氰酸酯基聚氨酯 - 和聚氨酯 - 环氧网络纳米复合聚合物组合物 优选天然或改性蒙脱石与具有至少一个环碳酸酯基团的单体或低聚物或其后者与环氧树脂的混合物的长宽比(长度/厚度)优选为10(nm) 固化剂,其是具有伯和/或仲氨基的单体或低聚物或其混合物。 纳米粘土的使用降低了凝胶时间,并增加了固化的聚氨酯和聚氨酯/环氧树脂混合物的粘附性,并且还降低了其吸水性。
