环保型脲醛树脂胶的合成

Synthesis of environment protection type urea-formaldehyde resin adhesive

用加入氧化剂的方法 ,将脲醛树脂胶中的游离甲醛氧化成甲酸 ,使游离甲醛含量降低到 0 .5 %以下。

This is reporting the way of modification with oxidizer. Free CH2O in ureaformaldehyde resin is oxidized to HCOOH, which makes the free CH2O content decreases to less than 0.5%.
