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 ClassⅡ of 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 low △Eη value 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.
