| The impregnation resin used to finish foil is urea formaldehyde resin mainly now, the advantages of UF resin is good impregnation performance, low price, but the moisture-resistance performance is bad. In the high moisture circumstance, finish foil will roll if the reservation is bad. When finish foil absorbed moisture more, it's bad to press. This paper aimed at the problem of moisture-resistance performance of finish foil, adopting melamine modified urea formaldehyde impregnated resin to make MUF.Studying MUF impregnation resin through the experiments of adding quantities of the melamine, control of the pH quality, temperature, reaction consistency, ratio of mol, control of the reaction end-point, project of the adding urea. Composed MUF meets storing life, content of free formaldehyde, pot life and the moisture-resistance performance of the finish foil. Urea formaldehyde resin import melamine had an obvious influence to the performances of the impregnated resin. The moisture-resistance performance of the UF resin boosts up obviously. The adding quantity of the melamine is 20% relative to the urea through the experiment. And through discussing the influence of the influencing factors to the performances of the modified resin, the resin recipe meets every performance is confirmed.This paper did experiments about adjusting resin experiment, under the conditions of meeting the pot life of the resin and pre-curing extent, through the method of adjusting the ratio of the curing reagent and prevent aggregation reagent to confirm the adjusting adhesive recipe. This can make out finish foil with good moisture-resistance and flexible performance. The experiment developed the moisture-resistance performance because the import of plasticizer. After painting, the moisture-resistance performance will enhance. These made the finish foil meet the requests of the storing and using in the high moisture circumstance.
