Abstract

The embodiment of the invention discloses an emulsion-type paper-plastic laminating adhesive. The emulsion-type paper-plastic laminating adhesive is prepared from the following components in mass ratio: acrylic acid, butyl acrylate, potassium persulfate, acrylamide, potassium bicarbonate, sodium alkyl benzene sulfonate, vinyl acetate and deionized water. Water is used as a dispersion medium of the emulsion-type paper-plastic laminating adhesive; printed matters laminated by the emulsion-type paper-plastic laminating adhesive have the characteristics of smoothness, cleanliness, flattening, high brightness, odourlessness, no pollution, easiness for coating and the like.

Description

technical field [0001] The invention relates to the field of paper-plastic laminating adhesives, in particular to an emulsion-type paper-plastic laminating adhesive and a manufacturing process thereof. Background technique [0002] Paper-plastic composite can make the surface of paper printed matter brighter and smoother, make the color more vivid and full of three-dimensional effect, and also play the role of moisture-proof, anti-fouling, anti-counterfeiting, folding resistance, wear resistance and so on. At present, it has been widely used and developed rapidly in the printing and packaging industries at home and abroad. The market demand for paper-plastic laminating adhesives is increasing day by day, and the market is mature with huge potential. Traditional paper-plastic laminating adhesives are mainly solvent-based laminating adhesives, but a large amount of solvent volatilizes during use and pollutes the environment, and is flammable and explosive, inconvenient to sto...
