Abstract: A kind of acrylic binder emulsion for the self-crosslinking pressure-sensitive protective film was prepared via pre-emulsification
semi-continuous polymerization. The molecular weight of resin was appropriately increased by the process of the oxidation-reduction polymerization,
and the cohesive forces were improved by the increase of the cross -linking degree by the addition of DAAM and ADH as the self -crosslinking
monomer. The cross-linking degree and the heat and wet-heat resistances of the protective film were further enhanced by the addition of SC-100 as
the crosslinking agent, and a series of formulations were obtained by adding different
