Embodiment 1
[0021] An inorganic modified asphalt, made by mixing the following raw materials in parts by weight: 100 parts of basic asphalt, 5.5 parts of boronite, 3.5 parts of albite, 4 parts of silica gel powder, 1 part of microcrystalline cellulose, and 0.5 part of triethanolamine , 2 parts of auxiliary agent; The auxiliary agent is Iranian rubber oil extraction oil. The base asphalt is Shell 90# base asphalt; the boron is manganese boronite, and the fineness is 100 mesh; the albite is albite powder, and the fineness is 100 mesh; the silica gel powder is column The layer chromatography silica gel powder has a fineness of 100-400 meshes; the microcrystalline cellulose is microcrystalline cellulose with a cellulose content ≥ 80%; the purity of the triethanolamine must be above 80%.
[0022] The preparation method of the inorganic modified asphalt in this example is as follows: heat the base asphalt to 120°C, then add triethanolamine and additives to the heated base asphalt, stir well and...
Embodiment 2
[0024] The inorganic modified asphalt of this embodiment is prepared by mixing the following raw materials in parts by weight: 100 parts of basic asphalt, 10.5 parts of boborite, 6.5 parts of albite, 6 parts of silica gel powder, 1.5 parts of microcrystalline cellulose, triethanolamine 0.5 parts, 3 parts of auxiliary agent; said auxiliary agent is furfural extract oil. The base pitch is Shell 90# matrix pitch; the boron is manganese boron, and the fineness is 300 mesh; the albite is albite powder, and the fineness is 100 mesh; the silica gel powder is column Layer chromatography silica gel powder, the fineness is 100-400 mesh;
[0025] The preparation method of the inorganic modified asphalt in this example is as follows: heat the base asphalt to 140°C, then add triethanolamine and additives to the heated base asphalt, and then add boborite, albite, and silica gel to the heated base asphalt. powder and microcrystalline cellulose; using a high-speed shearing machine to shear t...
Embodiment 3
[0027] The inorganic modified asphalt of this embodiment is prepared by mixing the following raw materials in parts by weight: 100 parts of basic asphalt, 15.5 parts of boronite, 10.5 parts of albite, 8 parts of silica gel powder, 2 parts of microcrystalline cellulose, triethanolamine 1 part, 4 parts of auxiliary agent; The auxiliary agent is Iranian rubber oil extraction oil. The base asphalt is Shell 90# base asphalt; the boron is manganese boronite with a fineness of 500 mesh; the albite is albite powder with a fineness of 300 mesh; the silica gel powder is column Layer chromatography silica gel powder, the fineness is 100-400 mesh;
[0028] The preparation method of the inorganic modified asphalt in this example is as follows: heat the base asphalt to 160°C, then add triethanolamine and additives to the heated base asphalt, stir well and then add boronite, albite, silica gel powder and microcrystalline cellulose; using a high-speed shearing machine to shear the obtained m...
