Cyanurotriamide modified urea resin and prepn. process

This invention provides a method for manufacturing melamine-modified urea-formaldehyde resin adhesive used on wood cement templates. The method adopts formaldehyde and urea at a molar ratio of 1.2-1.4 as the raw materials, and urea is added into formaldehyde in four times. Before the first time of urea addition, formaldehyde is activated at 50 minus or plus 5 deg.C for 15-25 min. in the third time of urea addition, melamine 3-20 wt. % of total urea is also added. After the fourth time of urea addition, ammonia solution is added for post treatment so that the content of free formaldehyde in the modified urea-formaldehyde resin adhesive is below 0.2 wt. %. at the same time the boiling water-resistance of the urea-formaldehyde resin adhesive can be improved. This invention can be used as a substitute for expensive phenol-formaldehyde resin adhesive; therefore the cost is reduced while the performance of wood cement templates can be guaranteed.
