The present application relates to the technical field of
high polymer material
silicone rubber, and particularly relates to a kind of
flame-retardant antistatic high-temperature resistant vulcanized
pipe and a preparation method thereof.The present application effectively solves the poor compatibility and performance conflict problem often occurred when realizing high
flame-retardant and antistatic function of traditional
silicone rubber
pipe material by constructing a unique "microscopic island structure".In the preparation process, vinyl MQ
silicone resin as a key "interface bridging" component can be preferentially adsorbed on the interface of different polar rubbers and wrapped modified
flame retardant to form a "core-shell" micro area, which not only prevents the interference of high-filled flame retardant on the conductive network, but also significantly enhances the
interfacial adhesion between
methyl silicone rubber and phenyl
silicone rubber two phases;At the same time, the assistant crosslinking agent
triallyl isocyanurate participates in
grafting reaction during
vulcanization process, and establishes a stable
chemical bond bridge between different rubber phases, which fundamentally avoids the
delamination phenomenon of the blending
system.
