| Abstract: | Urea-formaldehyde resins are widely used as wood adhesives. The preparation,curing mechanism,modified methods and the future development of the urea-formaldehyde resins were summarized. Effects of reaction condition,especially the pH values,on the performance of urea-formaldehyde were discussed. Modes of modification of urea-formaldehyde resin were listed to decrease its formaldehyde emission and improve its water resistance. Their properties after modification were also studied. The application of curing a... |
