The invention discloses a self-crosslinkable
flame-retardant
ethylene propylene rubber self-
adhesive tape and a preparation method thereof. The self-crosslinkable
flame-retardant
ethylene propylene rubber self-
adhesive tape comprises the following
raw material components in parts by
mass: 60-75 parts of
ethylene propylene
diene monomer, 10-30 parts of halogenated
butyl rubber, 10-50 parts of a heat-resistant
polymer, 3-12 parts of tackifying resin, 5-30 parts of operating oil, 100-150 parts of a
flame-retardant filler and 6-15 parts of an auxiliary agent. The tackifying resin comprises one or more of
alkyl phenolic resin and halogenated modified resin thereof, and aralkyl phenolic resin and halogenated modified resin thereof. The prepared
adhesive tape is convenient to install, resin containing active groups is selected as tackifying resin for
raw material components, on the basis that the adhesive tape has good
viscosity, the adhesive tape can be slowly cross-linked in the using process (90 DEG C or above), and therefore the
heat resistance and the
aging resistance are improved; meanwhile, the heat-resistant
polymer is added, so that the
heat resistance in the preparation and use processes can be ensured; and a flame-retardant filler matched with the formula
system is further added, so that the
system has good flame retardance.
