| Abstract: | This article introduces the producing method of low toxic urea formaldehyde resin adhesive which contains dissociate formaldehyde. This adhesive of high strength is applied in civil engineering. The factors influencing the adhesive strength including raw material purity, molar rate of urea and formaldehyde, and reaction temperature and time are covered in this thesis. Under certain acid and temperature conditions, urea added in batches to the phased reaction, a stable gluey liquid high strength adhesive for planks of building is produced. |
| Keywords: | urea formaldehyde resin adhesive low toxic |
