Abstract
The invention discloses a modified urea-formaldehyde resin adhesive used for high-dampness-proof fiber boards, wherein the modified urea-formaldehyde resin adhesive is prepared with formaldehyde, urea, a less amount of melamine and oxidized starch as raw materials. The adhesive is prepared by means of modification of a conventional process and is prepared through a weak acid-neutral-weak alkali process with one time of the formaldehyde and three times of the urea, so that the adhesive has a net-like modified structure of both Uron ring and tri-nitrogen heterocyclic ring. Not only are a reaction activity and a hot-pressing curing effect of a hydroxymethyl molecule group of the adhesive enhanced, but also the hydrophilic groups are effectively sealed. By means of the adhesive for preparing the fiber boards, the fiber boards are significantly enhanced in water tolerance and bonding strength. A problem that the fiber boards are liable to expand and deform and are poor in strength under a high-damp environment is solved. The adhesive has the functions of being waterproof and environmental-protective and prolonging the service life of the fiber boards.
