To find a new way of making full utilization of recycled office wastepaper,the authors made experiments to determine the feasibility of using it for making paper chipboard.They conducted an orthogonal experiment to analyze the effect of UF resin consumption,as well as hot-pressing time,pressure and temperature on the board’s mechanical properties.They also chose two kinds of pulps,CTMP and bamboo semi-chemical pulp,as reinforcing fiber to be added to the chips to improve the board properties.The results showed that when adding 30% bamboo semi-chemical pulp（to the absolutely dry chips）,15% resin,pressing temperature of 170℃,and pressure of 8 MPa for 480 seconds,the resulting MOR,MOE and IB values met the requirements of the national standard for particleboard.
