Three mixed liquids, Styrene, Methylmethacrylate and Vinyl acetate were used to soak poplar veneer to obtain strengthen poplar veneers. The optimal molar ratio was fixed on 1:2:1.Soaking and polymerization technology were obtained as pressure 0.4Mpa, packing time 60 minutes, polymerization temperature 80°C, polymerization time 6 hours, cobalt naphthenate 2%, zinc chloride 6%, and azobisisobutyronitrile 3%. The impact of high temperature on the conversion was significant in the chosen level, other factors on the conversion rate was not significant. |
