Abstract

The invention discloses water-based aluminized film composite glue and a preparation method thereof, and belongs to the field of adhesive manufacture. The composite glue with 45 to 50 percent of solid content is prepared from monomers, composite emulsifier, initiator, buffering agent, pH regulator, water-based auxiliary agents and deionized water serving as raw materials by pre-emulsifying, seed reaction, polymerization reaction and compounding; the monomers comprise hard monomer, soft monomer and functional monomer, wherein the hard monomer consists of styrene and vinyl acetate; the soft monomer consists of butyl acrylate; and the functional monomer consists of any one of acrylic acid and methacrylic acid, any one of hydroxyethyl acrylate and hydroxypropyl acrylate, and N-hydroxymethyl acrylamide. The composite glue has good stability and low cost, and can improve the adhesive force and the peeling strength of an adhesive film on an adhesive base material. By adding various water-based aids with excellent performance, the foam of the composite glue in use is reduced, and the wetting leveling property of the emulsion on the surface of the aluminized film is improved so that the coating property of the glue is improved and the transparence is better after the film is formed.

Description

technical field [0001] The invention belongs to the field of adhesive manufacturing, and in particular relates to a novel water-based aluminized film 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 cigarette boxes. It combines various aluminized films (or laser films) with cardboard or coated paper, and uses the bright appearance of the aluminized film (or laser film) to increase the aesthetic effect of the packaging box, improve the packaging grade, and attract consumers' attention , where the adhesive plays a very important role. [0003] At present, there are mainly two types of aluminized film composite adhesives: emulsion type and solvent type. Solvent type composite adhesives have environmental protection and safety problems due to the use of organic substances su...
