Research on the recycled 3 years,6years and 12years particleboard furniture, the results found:(1) The renewable particle produce by boiling water are better than by direct shatter, the renewable particle can basically maintain the original particle form; (2) Under the experimental conditions, using 100% recycled particleboard furniture, the renewable particleboard produced by boiling water, the MOR can over 13.6Mpa, the IB can over 0.42Mpa, the properties can reach or over the indicators in GB 4897.3-2003, however, the renewable particleboard produced by direct shatter can not reach this indicatoes. (3) Melamine materials and paint materials have impact in renewable particleboard, without paint materials the renewable particleboard are better; without melamine materials the renewable particleboard MOR and MOE are better, but IB and TS are worse.Using self-produced particleboard furniture panels, simulation accelerated aging to about using 10 years, then produce renewable particleboard, research on the properties of renewable particleboard, the results found, (1) The renewable particleboard produced by different aging furniture panel, the MOR can over 21.8Mpa, the MOE can over 3060MPa, the IB can over 0.61Mpa, the 2hTS can control under 2.6%. the properties can reach the indicators in GB 4897.7-2003. (2) Renewable particleboard produced by surface gluing melamine, gluing wood paper and thin wood, the MOR can over 23.1Mpa, the MOE can over 3296Mpa,the IB can over 0.72 Mpa, the porperties are better than original particleboard surface decorating by direct painting and no decorating; (3) Under the experimental conditions, renewable particleboard MOR compared with the original particleboard is declining, however, MOE, IB and TS is better than original particleboard.Through recycling of used particleboard and self-produced particleboard, the experiment found the time having an influence on MOR, the performance is declining the opportunity, however, MOE, IB and TS are better than original particleboard. Preliminary analysis the reasons may be the adhesiv having some enhancement in renewable particle, more precise explanation need for precise analysis the microstructure of renewable particle and other experiments, further research is being plannedThis paper also research the methods of improving renewable particleboard properties, the experimental results found, (1) Renewable particleboard produced by boiling water and high voltage boiling are better than produced by steaming and direct shatter treatment methods; (2) Renewable particleboard treatment by boiling water, the density controling in 0.7-0.75g/cm3, the porperties will be able to achieve the ideal targets. (3) Renewable particleboard treatment by boiling water, glue spread in 8%-12% scope, the physical and mechanical properties of renewable particleboard are no significant impact, MOR only enhence 1.1Mpa, MOE enhence 110 Mpa, IB enhence 0.04Mpa.
