| Abstract: | Urea-formaldehyde resin adhesive used in chipboard has the defects of unsound heat resistance, water resistance and high content of free formaldehyde. In view of these, this text delivers a research on modifying methods of urea-formaldehyde resin. Excellent modified urea-formaldehyde resin can be obtained by lowering the mole ratio between urea and formaldehyde, changing the manner of feeding, putting in modifying components and so on. |
