But it were be used in some specific applications.3 Optimized formula 1:A method to treat wood with the mixed solution of water-soluble PF and borate is first put forward to increase the retention of boron; in the decay and termite resistant tests, the specimens treated with high concentration of borates and PF had no mass loss; the dimensional stability and water absorption and mechanical strength of treated wood have been improved a lot; FTIR analysis showed that the PF reacted with certain groups of the wood cell wall material(cellulose, hemiceilulose and lignin).SEM analysis showed that the PF had nice permeability to the wood and could reach all parts of the wood. PF could attach to the cell wall of wood firmly after curing at high temperature, which would fix borate in the timber commendably.4 Optimized formula 2:A new method to treated wood with quaternary ammonium salt and inorganic borate in two steps is posted for the first time.
3优选配方一：首次提出将水溶性酚醛树脂与硼酸盐混合后处理木材以提高处理材中硼的保持率；在室内耐腐及抗白蚁实验中，硼酸盐浓度较高时处理材几乎没有质量损失；处理材的尺寸稳定性、吸水性以及力学强度都得到了很大程度的改善；FTIR分析表明酚醛树脂与纤维素、半纤维素以及木素中的一些基团发生了作用；SEM分析表明所合成的水溶性酚醛树脂对木材的渗透性很好，能够到达木材内的各个部位，并且酚醛树脂在高温固化之后，牢牢的附着在木材的细胞壁上，从而将硼酸盐很好的固定在木材内。
