Abstract

The invention relates to a water-based anodized aluminum adhesive resin with high adhesion and high temperature resistance and a preparation method thereof. The composition of the water-based anodized aluminum adhesive resin is as follows in terms of mass fraction: 20-30 parts of acrylonitrile, diethylamino methacrylate 25-35 parts of ethyl ester, 35-55 parts of hydroxypropyl acrylate, 4-8 parts of emulsifier, 15-24 parts of deionized water, 0.1-0.4 parts of initiator, balanced combination of hard monomers with high glass transition temperature and high viscosity Cohesion, solvent resistance, self-thickening, and hydroxypropyl acrylate are more hydrophilic, sticky, and peel strength. The pre-emulsification process is used to prepare the seed pre-emulsion first, and then add the emulsion and initiator dropwise by heating Polymerize cross-linked micelles, increase the concentration of free radicals and branched chain products, ensure the dispersion, heat transfer and mass transfer performance of the system, improve the stability of the system, fully emulsify and reduce the phenomenon of implosion and gelation, and the water-based anodized aluminum adhesive resin is heat-resistant Stability performance and adhesive curing performance are improved, anodized aluminum hot stamping performance, stickiness, peel strength are improved, and the scope of applicable substrates is broadened.

Description

technical field [0001] The invention relates to a water-based anodized aluminum adhesive resin with high adhesion and high temperature resistance and a preparation method thereof, belonging to the technical field of the water-based anodized aluminum adhesive resin. Background technique [0002] Water-based anodized aluminum adhesive resin is a kind of hot stamping plastic film such as PP, PVC, PET, acrylic, ABS, PC and various products, all kinds of UV ink varnish paper products with smooth surface, leather and synthetic leather The water-based adhesives of other substrates have a better hot stamping effect than traditional oil-based adhesives, and meet the environmental protection requirements of packaging, pharmaceutical and cosmetic industries for organic solvent residues. When anodized aluminum is hot stamped, with the help of moving pressure and temperature, the printed matter and the hot stamping foil are pressed against each other in a short period of time to achieve ...
