Waterborne aluminium foil adhesive and preparation method thereof

Abstract

The invention discloses a waterborne aluminium foil adhesive and a preparation method thereof and belongs to the field of adhesives. The aluminium foil adhesive is a composite adhesive with solid content of 40 to 50 percent, which is prepared by using monomers, an emulsifier, protective colloid, an initiator, a buffer, a pH (potential of hydrogen) regulator, a plasticizer, a waterborne assistant and deionized water as the raw materials through pre-emulsification, seed reaction, polymerization reaction and compounding. The monomers in the raw materials comprise hard monomers, soft monomers andfunctional monomers, wherein the hard monomers adopt vinylacetate and methyl acrylate; the soft monomers adopt ethyl acrylate and butyl acrylate; and the functional monomers adopt any one of acrylic acid or methacrylic acid and N-hydroxymethyl acrylamide. The waterborne aluminium foil adhesive has the advantages of low cost, high stripping strength and good leveling property and is simple and convenient to operate.

Description

technical field [0001] The invention belongs to the field of adhesive production, in particular to a water-based aluminum foil adhesive and a preparation method thereof. Background technique [0002] Aluminum foil paper has good moisture-proof, fresh-keeping, taste-keeping and decorative properties. It is widely used in cigarettes, candy and other packaging. Products using this composite process have a strong metallic texture, bright colors, tough and light texture, and are stretchable. Strong, gradually become the choice of many users. [0003] Aluminum foil glue is mainly used for bonding aluminum foil and paper to prepare aluminum foil paper, which is widely used in the packaging material industry. At present, the aluminum foil glue used for compounding aluminum foil paper mostly uses polyvinyl acetate (PVAc) white latex or starch glue. This kind of glue has low bonding strength, poor peel strength, poor folding resistance of composite products, and poor overall performa...

Problems solved by technology

At present, the aluminum foil glue used for compounding aluminum foil paper mostly uses polyvinyl acetate (PVAc) white latex or starch glue. This kind of glue has low bonding strength, poor peel strength, poor folding resistance of composite products, and poor overall performance. good with flaws

In addition, due to its high viscosity, poor leveling, inconvenient use, and extremely difficult cleaning, it is difficult to meet the high efficiency requirements of users.
