Embodiment 1
[0007] Embodiment 1: use resin, polystyrene, styrene, tert-butyl ester, methyl ethyl ketone, coarse sand, and cloth scraps as raw materials to make water grate well covers. Take 100Kg of resin, 40Kg of polystyrene, 80Kg of styrene, 2.5Kg of tert-butyl ester, 1.5Kg of methyl ethyl ketone, 400Kg of coarse sand, and 25Kg of cloth scraps, then fully stir and mix the above materials, and then put the mixture in a special mold. The mold is heated to 143° C., pressurized to 160 T, and held for 6 to 8 minutes to release the mold to obtain a water grate well cover.
Embodiment 2
[0008] Embodiment two: take resin, polystyrene, styrene, tert-butyl ester, methyl ethyl ketone, stone, cloth scrap as raw material to make road manhole cover. Take 100Kg of resin, 40Kg of polystyrene, 80Kg of styrene, 2.5Kg of tert-butyl ester, 1.5Kg of methyl ethyl ketone, 600Kg of stones, and 25Kg of cloth scraps, and then fully stir and mix the above materials, and then put the mixture in a special mold. Heating to 143°C, pressurizing to 160T, keeping the pressure for 6-8 minutes, demoulding to obtain the road manhole cover.
[0009] In the present invention, cloth scraps of different materials are blended with resin, coarse sand or stones, and an appropriate curing agent is added. Under a specific pressure and temperature environment, road grate well covers or road inspection well covers of different specifications are produced with molds of corresponding specifications. Simultaneously, the steel skeleton moving force frame is pre-installed in the present invention, so tha...
