以大豆蛋白粉、生化复合改性剂为主要原料,制备了无醛胶粘剂;然后采用添加法制备了阻燃型大豆蛋白胶粘剂,并将其应用于无醛阻燃刨花板的制备。研究结果表明:添加磷-氮-硼阻燃剂(FR-B)时,所制备的阻燃无醛胶粘剂具有相对最好的综合性能,其不仅能显著提高刨花板的阻燃性能,而且对刨花板的力学性能影响较小;当w(FR-B)=7%(相对于刨花质量而言)时,刨花板的阻燃性能相对最好,并且其各项力学性能均满足GB/T 4897—2015标准中的指标要求。
Using soybean protein powder and biochemical compound modifier as the main raw material, the aldehyde-free adhesive was prepared. Flame-retardant soybean protein adhesive was prepared by adding method and applied to the preparation of formaldehyde-free flame-retardant particleboard. The results show that the flame retardant non-formaldehyde adhesive prepared by adding phosphorus-nitrogen-boron flame retardant (FR-B) has the best comprehensive performance, which not only can significantly improve the flame retardant properties of particleboard, (W-FR) = 7% (with respect to shaving quality), the flammability of particleboard is the best, and its mechanical properties meet the GB / T 4897-2015 Standard requirements in the index.
