Abstract

The invention belongs to the technical field of isolation facilities, and specifically discloses a lightweight isolation pier material, which is prepared from the following raw materials: cement, clay, coarse sand, biochar, asbestos, chitosan, ABS, EVA, polypropylene, Epoxy resin, polyvinyl chloride; the preparation steps are as follows: (1) Mix and stir ABS, EVA, polypropylene, epoxy resin, and polyvinyl chloride to obtain mixture A; (2) Mix cement, clay, coarse sand, asbestos, Mix biochar, chitosan swelling solution and appropriate amount of water to obtain mixture B; (3) place the prepared alloy skeleton in the mold according to the required specifications of the isolation pier, pour mixture B into it, and release it after natural drying The embryo body of the bottom tire is obtained by curing; (4) a casing made of the mixture A coated on the periphery of the embryo body of the bottom tire; (5) a fluorescent pattern is painted on the side of the casing, and an isolation pier material is obtained after drying. The isolation pier material prepared by the invention has good noise reduction and sound absorption performance, and can ensure driving safety.

Description

technical field [0001] The invention relates to the technical field of isolation facilities, in particular to a lightweight isolation pier material. Background technique [0002] Isolation piers are one of the main traffic facilities, which can effectively eliminate vehicles from occupying sidewalks, sidewalks, and fire exits, and play the role of dividing roads, separating areas, diverting traffic, and guiding warnings. With the continuous improvement of people's pursuit of driving safety and comfort, more and more roads have been built for noise protection. At the same time, as there are more and more vehicles on the road, the road is built longer and wider, and the emission of vehicle exhaust and the dust raised by traffic flow are important factors of air pollution. The smog weather formed by PM2.5 seriously affects people's health. The living space, the road absorbs the heat energy of the sun, the metal shell of the car absorbs heat and the hot smoke emitted by the exh...
