The invention relates to a composition of waterborne laminating
adhesive and a method for preparing the same. The waterborne laminating
adhesive comprises the following components in percentage by weight: 10 to 20 percent of soft
monomer, 25 to 30 percent of hard
monomer, 2 to 4 percent of functional auxiliary agent, 0.5 to 2 percent of emulsifier, 0.08 to 0.3 percent of initiator, 0.2 to 0.6 percent of Ph buffer
regulator and 0.5 to 1.2 percent of functional assistant and 45 to 55 percent of
softened water. Because a waterborne medium is used, so that no
pollution is caused in the production process, damages caused by organic solvents to production persons and users are eliminated, and the fire risks in production and use processes are greatly reduced. The waterborne laminating
adhesive has the advantages of higher bonding force,
bonding strength,
water resistance and
solvent resistance, complete water base, no organic solvents such as
benzene and
ethylene dioxide, no
toxin nor harmlessness, high product applicability, unnecessary modification of the original equipment, the complete replacement of the
solvent-type laminating adhesive, no metachromatism with gold
powder, the suitability for production of high-grade products, easily bought raw materials, simple production process, easy operation and the like.
