Abstract:
Urea-formaldehyde resin is a kind of t radit ional wet-strength ag ent . Because of it s cheaper and striking w et-st rength ef fect, it has alw ays been used w idely. But w hen it is produced or used, it can g ive out f ree formaldehyde that is very harmful to health. This paper focuses on the resin synthet ic condition in w hich formaldehyde can be partlly or w holly used to subst itute for g lyox al, and then the w et-st reng th effect is studied. In addition, the reaction mechanism and mechanism of the wet-strength agent are also studied.
