Water-based ink adhesive for printing gold and silver cardboard and preparation method thereof

The invention relates to a water-based ink adhesive for printing a gold and silver cardboard and a preparation method thereof. The water-based ink adhesive is prepared from acrylic acid, butyl acrylate, acrylic acid-2-ethyl hexyl ester, methyl methacrylate, styrene, N-hydroxymethyl acrylamide, benzoyl peroxide, isopropanol and ammonia water. The adhesive provided by the invention has the beneficial effects that 1, the water-based ink adhesive in the production and using processes is free from environmental pollution, and the product is colorless, non-toxic, free from irritant odor and harmless to human body; 2, the product has a block hard and soft chain structure, so that the product has a high glass transition temperature hard chain section, thus, the ink has good hardness, glossiness and heat resistance; a low glass transition temperature soft chain section increases the congruency of the ink and the adhesive, so that the ink has excellent film forming property, flexibility, water resistance and adhesive c
