摘　　要：本文采用正交试验法，主要探讨了焦油酚－苯酚－甲醛共缩聚树脂的原料配比及合成工艺，并借助凝胶色谱（ＧＰＣ）仪测定了焦油酚的平均分子量。研究结果表明：用焦油酚替代３０％的苯酚合成胶合性能优异的酚胶是可行的。通过合理地调整原料配比及合成工艺参数，其胶合性能满足ＧＢ９８４６－８８Ⅰ类合板和ＪＡＳ特类合板的要求，其平均胶合强度分别为１．２６ＭＰａ和１．２２ＭＰａ，平均木材破坏率分别为５０％和６５％。In this paper, the formation and synthesis process of tar-phenols-phenol-formaldehyde co-polymerization resin was investigated by orthogonal method, and average molecular weight of tar-phenol was determined by means of gel penetration chromatograph(GPC).The results indicated that it was feasibility that excellent performance phenolic resins had been synthesized with tar-phenol instead of 30 percent phenol. Bonding properties of plywood can met requirement of GB 9846-88 Ⅰ and JAS special plywood by adjusting ratio of raw materials and parameter of synthesizing technology reasonable, the average shear strength is 1 26MPa and 1 22MPa. the average wood failure rate is 50% and 65% respectively.
