一种高胶合性阻燃胶合板的制备方法
摘要：
本发明公开了一种高胶合性阻燃胶合板的制备方法，操作步骤：(1)质量浓度为10～20％的磷酸氢二铵溶液，与质量浓度为0.5～1.0％氢氧化铝溶液、质量浓度为0.3～0.6％的硫化镍溶液混合，即得浸渍液；(2)将自制的MUF树脂调胶，然后涂施于单板上，并在125～135℃，压力为1.2～1.5MPa热压，即得素胶合板；(3)将步骤(2)所得素胶合板在步骤(1)中制备所得浸渍液中浸渍，素胶合板浸渍过后，烘干至含水率为8～12％，即得。本发明方法制备所得阻燃胶合板胶合强度增强，且大大改善了阻燃胶合板的亲水性，从而实现提高阻燃胶合板质量的目的；进一步的，本发明方法操作简捷，降低了能耗。
摘要（英）：

The invention discloses a preparation method of a flame-retardant plywood with high bonding strength, comprising the operation steps of (1) mixing a diammonium hydrogen phosphate solution with the mass concentration of 10-20%, an aluminum hydroxide solution with the mass concentration of 0.5-1.0% and a nickel sulfide solution with the mass concentration of 0.3-0.6% to obtain an impregnation liquid; (2) making glue by using self-made MUF resin, then, applying the glue on a veneer, and carrying out hot pressing at the temperature of 125-135 DEG C and the pressure of 1.2-1.5MPa to obtain a plain plywood; and (3) impregnating the plain plywood obtained in the step (2) into the impregnation liquid prepared in the step (1), and then, drying the impregnated plain plywood until the moisture content is 8-12% to obtain the flame-retardant plywood with high bonding strength. The flame-retardant plywood prepared by using the preparation method disclosed by the invention is improved in bonding strength, and the hydrophility of the flame-retardant plywood is greatly improved, so that the aim of improving the quality of the flame-retardant plywood is achieved; and furthermore, the method disclosed by the invention is simple in operation and capable of reducing the energy consumption.
