Abstract

The invention discloses waterborne gravure printing aluminum-coated compound glue, and belongs to the field of adhesive preparation. The compound glue comprises monomers, deionized water, a compound emulsifier, an initiator, a buffer, and a waterborne additive of a pH (potential of hydrogen) regulator; the viscosity of the compound glue is 300 to 500 mPa.s, and the solid content of the compound glue is 40 to 50 percent; the monomers comprise a hard monomer, a soft monomer and a functional monomer; the hard monomer comprises methyl methacrylate and vinyl acetate; the soft monomer is butyl acrylate; the functional monomer comprises any one from acrylic acid and methacrylic acid, any one from 2-hydroxyethyl acrylate and hydroxypropyl acrylate, and acrylonitrile; and the compound emulsifier comprises polyoxyethylene ether sodium sulfonate, alkyl phenol polyoxyethylene ether and allyloxy hydroxyl propane sodium sulfonate. The compound glue is suitable for the processing technology of first gravure printing and then compounding, so as to prepare more beautiful compound paper material coated with aluminum films.

Description

technical field [0001] The invention belongs to the field of adhesive manufacturing, in particular to a water-based gravure aluminized composite adhesive and a preparation method thereof. Background technique [0002] Aluminized film composite paper has a very beautiful effect, and is now widely used in the packaging of various high-end toothpaste boxes, cosmetic boxes, jewelry boxes and wine boxes. At present, this kind of material is generally combined with aluminized film and cardboard or coated paper, and then printed on the surface of the substrate plastic (such as PP, PET) of the aluminized film. Since the surface printing method is used, the ink used is more It is a polyamide surface printing ink, its color is not as bright as that of the inner printing ink (such as polyurethane ink), and it uses benzene-based toxic solvents, which is not environmentally friendly. However, if the process of first printing (gravure printing) on ​​the surface of the plastic film is use...
