Abstract
The modified urea-formaldehyde resin with low formaldehyde release was synthesized with different kinds of additives in this paper. And the curing characteristics were studied mostly. The results indicated that: the urea-formaldehyde resin with additive 1+2+3 showed the fastest cure rate, which improved about 15% compared with the blank sample, but the mechanical properties was poor. So the synthesis process was optimized based on the addition of assistant 1+2+3, the results showed that:â�? melamine has a very significant effect on reducing free formaldehyde, when the added amount reached 3%, the formaldehyde release was only 0.28mg/L;â�?¡increased the viscosity of the resin can improve the bonding strength of the adhesive obviously.
