摘　　要：分别利用单一催化剂NaOH以及NaOH与金属化合物复合催化剂,合成了生物油-酚醛树脂胶粘剂,并对胶粘剂的胶合强度和凝胶时间进行了研究。研究发现,以复合催化剂制备的生物油-酚醛树脂胶粘剂的胶合强度比以单一催化剂制备的强度高,且凝胶时间短,其中以复合催化剂(Na2CO3+NaOH)的作用最显著。Taking NaOH and mixtures of NaOH and metallic compound as the catalysts respectively, bio-oil-PF resins were synthesized. Through comparing the bonding strength and curing time of various resins, it was found that the bonding strength of the bio-oil-PF resin made with combined catalysts is higher than that of the bio-oil-PF resin made with single catalyst and the curing time of the bio-oil-PF resin is shortened by multiple catalysts. The catalyst （ Na2CO3 ＋ NaOH ） achieved a remarkable result.
