Disclosed is a moisture-cured polyurethane adhesive containing 0.5% to 40% by weight of layered double hydroxide particles dispersed in the polyurethane. Also disclosed is a curable resin compositionincluding a polyurethane prepolymer with an isocyanate component and a polyol component. The polyurethane prepolymer is curable with moisture and contains layered double oxide particles dispersed in the prepolymer in an amount from 0.5% to 40% by weight of the composition. A method of making a polyurethane adhesive is also disclosed. 公开了一种湿气固化的聚氨酯粘合剂，其含有按重量计0.5％至40％的分散于聚氨酯中的层状双氢氧化物颗粒。还公开了一种可固化的树脂组合物，其包括具有异氰酸酯组分和多元醇组分的聚氨酯预聚物。聚氨酯预聚物用湿气可固化并且以组合物的按重量计0.5％至40％的量含有分散于预聚物中的层状双氧化物颗粒。还公开了一种制备聚氨酯粘合剂的方法。
