Abstract With wheat straw, wood and environmentally friendly and flame retardant inorganic adhesive as major raw mate-rials, inorganic particleboard with a uniform mixture of wheat straw and wood was manufactured by hot-pressing technology.The effect of wheat straw-wood ratio, adhesive consumption, hot-pressing time and hot-pressing temperature on physical and mechanical properties of the board was studied, and influencing mechanism of them on the board′s properties was analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Results showed that modulus of rupture (MOR), modulus of elasticity (MOE) and internal bond strength (IB) of the board gradually increased while thickness swelling (TS) of that gradually decreased with declining wheat straw-wood ratio; optimal ratio was 4∶6. With increase of adhesive consumption, MOR and MOE firstly increased and then decreased, meanwhile, IB increased gradually and TS decreased gradually; MOR and MOE reached the maximum as 15.5 MPa and 3 110 MPa respectively when adhesive consumption was 63%, IB and TS was 0.47 MPa and 5.5% at this point. MOR, MOE and IB gradually increased while TS gradually decreased with increase of hot-pressing temperature and hot-pressing time; MOR, MOE and IB reached the maximum as 16.8 MPa, 3 350 MPa and 0.56 MPa, while the TS reached the minimum as 3.5% with hot-pressing temperature of 100 ℃ and hot-pressing time of 30 min. Optimal process was as follows: wheat straw-wood ratio of 4∶6, adhesive consumption of 63%, hot-pressing time of 30 min and hot-pressing temperature of 100 ℃.
