Abstract

The invention discloses a bridge expansion joint dustproof seepage-proof adhesive which comprises a modified asphalt cement, a base cloth, a high-temperature-resistant polyethylene (PE) film and a high-temperature-resistant PET silicone oil film, the modified asphalt cement is dip-dyed on the base cloth, the high-temperature-resistant polyethylene film is located on the lower surface of the base cloth, and the high-temperature-resistant silicone oil film is located on the upper surface of the base cloth. The modified asphalt cementing material is prepared from the following raw materials in parts by weight: 50 to 60 parts of matrix asphalt, 4 to 10 parts of SBS (Styrene Butadiene Styrene), 15 to 25 parts of rubber powder, 2 to 5 parts of petroleum resin, 13 to 18 parts of extract oil and 0.05 to 0.15 part of stabilizer, the rubber powder is 20-40-mesh desulfurized rubber powder, the stabilizer is a sulfur-containing stabilizer, the extract oil is furfural extract oil, and the petroleum resin is C9 petroleum resin.

Description

technical field [0001] The invention relates to the technical field of bridge expansion joints, in particular to a dust-proof and anti-seepage adhesive for bridge expansion joints and a preparation method thereof. Background technique [0002] Due to the large traffic volume, heavy or overloaded vehicles in China, tight construction schedule, and defective quality control, bridge expansion joints directly bear the repeated rolling impact of vehicle loads, and the damage of bridge expansion joints is very prominent. The damage of expansion joints is reflected on the road surface, that is, the concrete protection belt is damaged, the rubber strip is damaged, the gaps are filled with debris, and the noise is loud when vehicles pass through (see Figure 1-3 ), affecting the driving comfort, reducing the road capacity, and at the same time bringing traffic safety hazards. As the anchored concrete of the expansion joint begins to gnaw and fall off, and finally, as the erosive mate...
