摘　　要：我国的生物质资源丰富,将其快速热解成生物油,作为优质化工原料应用,可实现其高值高效应用。本文对以生物油制备的环境友好型生物油淀粉胶黏剂基本性能进行研究,结果表明,其湿胶合强度可达到国标Ⅱ类胶合板标准,其黏度可以满足胶合板工业化生产需求;生物油淀粉胶黏剂流变行为呈现出明显的剪切变稀特征,是典型的假塑性流体,流动活化能ΔE_η为9.67 kJ·mol^(-1),表明其具有良好的流动性和应用潜力;通过对比不同生物油加入量的BOS胶黏剂湿胶合强度、流变性和热稳定性的研究发现,生物油的加入可改善BOS胶黏剂的耐水性,促进其固化,并增强其热稳定性。Biomass is abundant and widely distributed in China.Fast pyrolysis of this renewable resource for bio-oil,a high quality starting material for chemical industry,is considered to be one of the most promising approaches for the achievement of its high value and efficient application.The basic performance of environment-friendly bio-oil starch adhesive(BOS adhesive)prepared from bio-oil was investigated.The results showed that the wet bonding strength of BOS adhesive reached the ClassⅡof Chinese Standard GB/T 17657 and the viscosity of this adhesive met well with the production demands of plywood industry.The rheological behavior of this BOS adhesive showed obvious shear-thinning characteristic,which meant that the BOS adhesive was typical pseudoplastic fluid.The lowΔEηvalue of BOS adhesive(9.67 kJ·mol?1)indicated that this adhesive has good liquidity,making it a great potential for industrial application and promotion.Comparative investigation on the strength,rheological property and thermal stability of BOS adhesive with different bio-oil content demonstrated that the bio-oil could improve the water resistance and thermal stability of BOS adhesive,and had a positive impact on the curing characteristics of BOS adhesive.
