The work aims to optimize the board preparation technology with the soluble starch as the adhesive and the feather fiber as the base material, and study its performance characteristics. The effect of board moisture content, adhesive consumption and hot-pressing temperature on the mechanical property of the feather fiberboard property was studied, and its optimized preparation technology was determined by orthogonal experiment and so on. Moreover, its board forming mechanism was studied through the Fourier infrared spectrum. In the optimized preparation technology of starch-based adhesive feather fiberboard, the adhesive consumption was 250 kg/m3, the moisture content of feather fiberboard blank was 15% and the hot-pressing temperature was 150 ℃. The biggest influencing factor was adhesive consumption. With the increase in the adhesive consumption, the internal bonding strength, static bending intensity, elastic modulus and 24 h thickness swelling rate of water absorption of the feather fiberboard increased gradually. When the adhesive consumption was 260 kg/m3, the internal bonding strength, static bending intensity, elastic modulus and 24 h thickness swelling rate of water absorption of the fiberboard were 0.69 MPa, 20.48 MPa, 2,675 MPa and 10.23%, respectively. The higher the starch content was, the stronger the fiberboard's water absorption was. After coating the paraffin, the water absorption was significantly reduced to 54.81% from 109.89% when uncoated with paraffin. The preparation of lightweight fiberboard with the feather is to certain extent feasible.
