改性不脱水脲醛树脂胶目前竹木加工行业用胶主要是豚醛树脂胶、酚醛树脂胶和三聚氰胺胶等，其中田醛树脂胶用量占80％以上，但普通脲醛胶尚存在耐水性差、游离醛含量高、需要真空脱水、出胶率低、成本高、设备复杂等缺点．因此对脲醛树脂进行改性研究是今后一段时间内竹木制品 Modified non-dehydrated urea-formaldehyde resin adhesives Currently, the plastics used in the bamboo and wood processing industry are mainly doufaldehyde resin, phenolic resin, and melamine rubber. Among them, the amount of aldehyde resin resin accounts for more than 80%, but ordinary urea-formaldehyde rubber still has poor water resistance and is free. High aldehyde content, need vacuum dehydration, low gel yield, high cost, complicated equipment and other shortcomings. Therefore, the research on the modification of urea formaldehyde resin is a period of time in the future.
