摘　　要：以蓝藻蛋白为研究对象,主要研究了NaOH降解工艺和杨木等离子体处理工艺对蓝藻蛋白基胶合板胶合强度和耐水性能的影响。结果表明:NaOH处理能够显著提高蓝藻蛋白胶黏剂胶合性能,但仅有干状胶合强度,不具有耐水强度;NaOH降解蓝藻蛋白粉最佳工艺为7%NaOH (占蓝藻蛋白),料液比为70∶50,处理时间为0.5 h,处理温度为30℃;等离子体适宜的处理功率和处理有时间有助于胶合强度和耐水性的提高,最佳处理工艺为处理工艺1 kW,处理时间1 min。In this paper, the effects of NaOH degradation process and poplar plasma treatment process for poplar plywood on bonding strength and water resistance of plywood with cyanobacterial protein-based adhesive were studied. The results indicated that:NaOH treatment could significantly improve the bonding performance of cyanobacteria protein-based adhesive, but only dry bonding strength does not have water resistance.The optimum process for degradation of cyanobacterial protein powder by NaOH is 7%(accounting for cyanobacterial protein),m(water): m(cyanobacterial protein powder)=70:50, treating time for 0.5 h and treating temperature on 30 ℃.The suitable treatment power and time of plasma are helpful to improve bonding strength and water resistance. The optimum treatment process is 1 kW and 1 min. The research work can provide reference for the modification and application of cyanobacterial protein adhesives.
