Background
The preimpregnated paper is used as facing material for artificial board with wide use and great use amount, and is special paper produced with decorative base paper and through soaking or printing treatment, and its quality depends greatly on the quality of the decorative base paper and soaking glue. Conventionally, aldehyde adhesives such as urea-formaldehyde resins and melamine-formaldehyde resins have been used in many impregnation treatments for decorative papers. The adhesive can endow paper sheets with strong hardness, adhesive force, scratch resistance, acid and alkali resistance, cigarette burning resistance and other physical properties after being thermally cured.
