The invention claims an aldehyde-free impregnating adhesive for decorative paper with physical strength meeting national standard requirements and a preparation method thereof, wherein the aldehyde-free adhesive comprises the following components: 40-60 parts of water-based acrylic emulsion, 5-15 parts of organic amine, 1-5 parts of cross-linking agent, 1-5 parts of polyvinyl alcohol, 5-10 parts of filler and 5-10 parts of water, the formaldehyde-free adhesive prepared by the method has no formaldehyde release, is safe and environment-friendly, wherein the water-based acrylate emulsion has small particle size, small molecular weight and moderate viscosity, so that the impregnating adhesive can better penetrate into paper, the problem of damage between decorative paper after the impregnating of common resin adhesive is solved, the introduced organic amine, polyethylene glycol and polyvinyl alcohol react with acrylate resin, and the adhesive coating amount and physical strength of the prepared adhesive impregnating are greatly improved compared with the corresponding values of pure resin adhesive impregnating decorative paper, thereby meeting the national standard requirements. |
