Problems solved by technology

Traditional road manhole covers include cast iron manhole covers, concrete manhole covers, plastic manhole covers, resin composite manhole covers, etc. Among them, cast iron manhole covers are easy to steal, concrete manhole covers are easy to peel off and break, plastic manhole covers are easy to deform and age, and resin compound manhole covers are easy to be brittle and cracked. The fibers used are glass fibers, because the glass fibers are brittle and easy to break under the action of a large impact

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...

Abstract

The invention relates to a high-toughness fabric fiber resin road manhole cover, which is made of resin, polystyrene, styrene, O butyl, methyl ethyl ketone, aggregate and fabric edge leftover according to the weight ratio of 1:0.4:0.8:0.025:0.015:4-6:0.25. A method of making the manhole cover includes: primarily mixing the materials at the temperature of 143 DEG C and under 160T pressure and placing the mixture into a mould with a steel ribbed movement frame, stripping after 6-8 minutes, and obtaining a resin fiber grate manhole cover or resin fiber road inspection manhole cover. By using the fibers of the fabric edge leftover, impact resistance of the manhole cover is improved greatly, and bearing capacity is improved. The high-toughness fabric fiber resin road manhole cover has the advantages of shock absorption, noise reduction, corrosion resistance, insulation, wear resistance, weather proofing, light weight, and low cost.

Description

technical field [0001] The invention relates to a kind of cloth fiber and resin blending, and under the action of a curing agent, the road manhole cover is manufactured by pressing through a mold, so as to achieve the functions of resource reuse and toughness enhancement. It belongs to new road building material technology. Background technique [0002] With the continuous construction and development of urban roads, the inspection well covers and drainage wells of various underground facilities under the roads are increasing day by day. Traditional road manhole covers include cast iron manhole covers, concrete manhole covers, plastic manhole covers, resin composite manhole covers, etc. Among them, cast iron manhole covers are easy to steal, concrete manhole covers are easy to peel off and break, plastic manhole covers are easy to deform and age, and resin manhole covers are easy to be brittle and cracked. The fiber used is glass fiber, because the glass fiber is brittle an...
