Additive of urea formaldehyde resin adhesive and preparation method thereof

The present invention provides a method for preparing the additive and urea-formaldehyde resin adhesive. The urea-formaldehyde resin additive adhesive parts 100 parts by weight of a modified wood flour, starch, 50-100 parts by acorn, 50 to 500 parts gypsum composition, which is a modified wood flour, acorn starch, gypsum prepared by mixing uniformly obtained. The urea-formaldehyde resin adhesive additive can be added to the flour in place of urea-formaldehyde resins, the preparation of plywood, the preload imparting good adhesive properties to ensure that wood-based panel production efficiency, and can effectively reduce the formaldehyde release, increased wood-based panels physical and mechanical properties.
