Abstract

The invention discloses a water-based dry-type complex film adhesive and a preparation method thereof, belonging to the field of preparation of adhesive. The preparation method of the complex film adhesive comprises the following steps: by using monomers, an emulsifier, an initiator, a buffering agent, deionized water, a pH regulator and water-based assistants as raw materials, emulsifying, carrying out seed reaction and polymerization reaction, and compounding to obtain the complex film adhesive of which the solid content is 45-55%, wherein the monomers comprise a hard monomer, soft monomersand functional monomers; the hard monomer is styrene; the soft monomers comprise butyl acrylate and 2-ethylhexyl acrylate; the functional monomers comprise acrylic acid or methacrylic acid, 2-hydroxyethyl acrylate or 2-hydroxypropyl acrylate, and diallyl phthalate; and the emulsifier comprises ammonium alkyl ether sulfate, sodium sulfosuccinate and sodium allyloxysulfonate in a weight ratio of 2:1:(0.4-0.8). The complex film adhesive has the advantages of high bonding strength, favorable affinity and covering performance for ink, and environment protection since the content of VOCs (volatile organic compounds) is lowered.

Description

Technical field [0001] The invention relates to the field of adhesive manufacturing, in particular to a water-based dry laminating adhesive and a preparation method thereof. Background technique [0002] Paper-plastic lamination is the use of adhesives to combine polypropylene (BOPP) or polyester (PET) films with paper prints, combining the advantages of paper and plastic film, so that the surface of the prints is brighter and smoother, and the color is more vivid It is rich in three-dimensional sense, and also has the functions of moisture-proof, anti-fouling, anti-counterfeiting, folding and abrasion resistance. It is widely used in decorative building materials, packaging materials, hardcover books, product advertisements or manuals, etc. With the development of the market economy and the improvement of consumption levels, the film is quite extensive. The adhesive used in paper-plastic compounding is called paper-plastic compound adhesive, or paper-plastic compound film adhes...
