The invention particularly relates to communication manhole covers and provides a composite manhole cover for a communication
base station. The composite manhole cover comprises a cover which is prepared from the following ingredients in parts by weight: 40-95 parts of
cyanate resin, 5-60 parts of low-
dielectric-constant fibers, 1-15 parts of
toughening modifier, 1-20 parts of curing agent, 1-20 parts of reinforcing filler, 0.5-10 parts of low-shrink additives, 0.01-2 parts of catalyst, 0.1-1 part of
lubricant, 0.01-1 part of UV absorbent, 0.1-0.6 part of
antioxidant and 0.1-0.5 part of pigments. According to the composite manhole cover for the communication
base station, the manhole cover is prepared by adopting the
cyanate resin, signals in a communication pipeline below an inspection shaft can be led out, and thus, the manhole cover can become an aerial transmitting
base station; the
cyanate resin has high mechanical properties, good
heat resistance and low water
absorption rate, meanwhile, the cyanate resin has most outstanding
dielectric properties among unsaturated resins and has low
dielectric constant and
dielectric loss.
