用可再生的生物质木质素替代三聚氰胺(MF),不仅可明显降低原料成本,减少造纸废液对环境的污染,保护环境,促进造纸废液的资源化利用,对人造板工业可持续发展具有重大意义,还可以降低MF树脂的交联度,因而增加其柔性和降低脆性。因此工业木质素及其改性 Replacing melamine (MF) with renewable biomass lignin can not only significantly reduce the cost of raw materials, reduce the pollution of papermaking effluents to the environment, protect the environment and promote the resource utilization of papermaking wastewater, but also have the advantages of sustainable development for the wood-based panel industry Significant, but also can reduce the degree of crosslinking of MF resin, thereby increasing its flexibility and reduce brittleness. Therefore, industrial lignin and its modification
