  A continuous process forms a unitary mat on a line having at least two conveyors spaced from each other. The process includes combining the isocyanate, an isocyanate catalyst, and a plurality of lignocellulosic particles to form a mixture and a self-polymerization product of the isocyanate in-situ in the mixture. The process also includes forming the unitary mat from the mixture on a first conveyer and transferring the unitary mat from the first conveyor to a second conveyor across a predetermined distance while maintaining structural integrity of the unitary mat. The lignocellulosic particles have a moisture content of 0.5 to 30 weight percent of water. Moreover, the continuous process is free of a step of adding water to the isocyanate, the isocyanate catalyst, the lignocellulosic particles, and/or the unitary mat.

  一种连续生产工艺可在一条至少有两个相互间隔的传送带的生产线上形成一个单元垫层。该工艺包括将异氰酸酯、异氰酸酯催化剂和多个木质纤维素颗粒结合在一起，形成混合物和异氰酸酯在混合物中的原位自聚合产物。该工艺还包括在第一传送带上将混合物形成单元毡，并在保持单元毡结构完整性的同时，将单元毡从第一传送带传送到第二传送带，传送距离为预定距离。木质纤维素颗粒的水分含量为 0.5-30 重量百分比。此外，连续工艺中没有向异氰酸酯、异氰酸酯催化剂、木质纤维素颗粒和/或单元毡中加水的步骤。

  This disclosure provides a plywood article that is pre-cured or cured. The plywood includes a first wood veneer, a second wood veneer disposed opposite the first wood veneer and an adhesive composition disposed between the first wood veneer and the second wood veneer. The adhesive composition is either cured or not cured. Prior to cure, the adhesive composition consists essentially of an isocyanate component and Kaolin. After cure, the cured adhesive composition consists essentially of a self-polymerization product of the isocyanate component and the Kaolin. The Kaolin is present in an amount of from greater than 10 to 50 weight percent based on a total weight of the adhesive composition. Moreover, each of the first and second wood veneers independently has a moisture content of from 0 to 45 weight percent.

  本公开提供了一种预固化或固化的胶合板制品。胶合板包括第一木单板、与第一木单板相对的第二木单板以及位于第一木单板和第二木单板之间的胶粘剂组合物。粘合剂组合物可以是固化的，也可以是未固化的。固化前，胶粘剂组合物主要由异氰酸酯成分和高岭土组成。固化后，固化的胶粘剂组合物基本上由异氰酸酯组分和高岭土的自聚合产物组成。高岭土的含量占粘合剂组合物总重量的 10%至 50%。此外，第一和第二木皮的含水量分别为 0 至 45 重量百分比。
