PURPOSE: To improve water resistance and sticking aptitude, and to elongate a pot life of an adhesive, by adding a ketone resin and a water-soluble acrylic compound to the starch adhesive for corrugated cardboard.
CONSTITUTION: A starch adhesive for corrugated board is blended with (A) a ketone resin (e.g., a condensate of acetone, MEK, methyl isobutyl ketone, etc. and formaldehyde) in the form of preferably a solution [preferably 20W70wt% solid content, ≤1,500cps Brookfield viscosity] and (B) a water-soluble acrylic compound (preferably poly-N-methylolacrylamide, etc.) in the form of preferably an aqueous solution (preferably 5W20wt% solid content, ≤5,000cps Brookfield viscosity), to give the desired adhesive. A blending ratio of the component A:B by weight is preferably (2:8)W(8:2).
