摘要
The present invention provides a flame-retardant pressure-sensitive adhesive, comprising reaction products of the following reaction compositions based a total weight of the reaction compositions as 100 wt. %: 35-99 wt. % of a (meth)acrylate copolymer containing a functional reactive functional group, the functional reactive functional group comprising one or a plurality of the following groups: carboxyl group, hydroxyl group and epoxy group; the (meth)acrylate copolymer containing the functional reactive functional group being formed by free radical polymerization of one or a plurality of monomers; and 1-65 wt. % of a reactive organophosphorus flame retardant capable of reacting with the functional reactive functional group, the reactive organophosphorus flame retardant being formed by reaction of reaction components comprising the following substances: a compound or oligomer containing n epoxy groups, wherein n>=2, and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide. The flame-retardant pressure-sensitive adhesive meets the halogen-free flame retardant requirements of the UL94V0 standard, and possesses high peel strength and high-temperature static shear strength.
