In this work, lactose-based adhesive with excellent boiling water resistance was prepared by the Maillard reaction, free radical polymerisation and multiple cross-linking network strategy using lactose and biomass polyamino compound (MP) as raw materials. On the other hand, the branched P-N synergistic flame retardant coating was constructed using the developed MP reacted with aminotrimethylene phosphonic acid (ATMP), which was used to coat the surface layer of laminated composite to give it flame-retardant properties. The dry shear strength, 3 h hot water (63 °C) wet shear strength, and 3 h boiling water wet shear strength of the laminated composite were 2.23 MPa, 1.14 MPa, and 1.02 Mpa, respectively, which were in line with the requirements of GB/T 9846-2015 standard (≥0.7 MPa). In summary, this work provides potential methods for the preparation of environmentally friendly boiling water resistant lactose-based adhesive and branched P-N synergistic flame retardant coating which were used for the construction of high performance wood laminated composites.

开发耐沸水乳糖基胶粘剂和支化PN协同阻燃涂料


本工作以乳糖和生物质聚氨基化合物（MP）为原料，通过美拉德反应、自由基聚合和多重交联网络策略制备了具有优异耐沸水性的乳糖基粘合剂。另一方面，利用所开发的MP与氨基三亚甲基膦酸(ATMP)反应构建支化PN协同阻燃涂层，用于涂覆层合复合材料的表层，赋予其阻燃性能。层合复合材料的干剪切强度、3 h热水（63℃）湿剪切强度、3 h沸水湿剪切强度分别为2.23 MPa、1.14 MPa、1.02 MPa，符合要求符合GB/T 9846-2015标准（≥0.7MPa）。综上所述，本工作为制备环保型耐沸水乳糖基胶粘剂和支化PN协同阻燃涂料提供了潜在的方法，用于构建高性能木质层合复合材料。
