The disclosure discloses a composition, an
adhesive, a tape and an optical cable, and belongs to the technical field of optical cables.The composition comprises a base resin and a
flame retardant, the base resin comprises
isooctyl acrylate and has a
mass percentage of 50-85%, the
flame retardant comprises a
phosphate ester
flame retardant and a
hypophosphite flame retardant, the
mass percentage of the
phosphate ester flame retardant is 1-30%, and the
mass percentage of the
hypophosphite flame retardant is 10-50%; the
hypophosphite flame retardant is selected from at least one of aluminum hypophosphite,
zinc hypophosphite, iron hypophosphite, aluminum diethyl hypophosphite, aluminum methyl hypophosphite and aluminum propyl hypophosphite.The
adhesive formed by the composition can be used as a bonding layer of a concealed optical cable, so that the bonding layer of the concealed optical cable has good transparency, flame retardance and yellowing resistance in addition to reliable bonding force.
