The invention discloses a
cold welding seam agent for a building road and a preparation method thereof, and relates to the technical field of preparation of constructional
engineering. The modified
asphalt is prepared from the following components in parts by weight: 10-12 parts of CoO.Co2O3, 10-20 parts of an
organic solvent, 6-8 parts of a flocculating agent, 3-8 parts of a stabilizer, 10-20 parts of chlorinated paraffin, 50-70 parts of matrix
asphalt, 0.5-1 part of a cross-linking agent, 8-10 parts of an emulsifier, 10-15 parts of 2-ethyl-4-methylimidazole, 15-20 parts of fibers and 50-60 parts of water. According to the
cold welding seam agent for the building road and the preparation method, the matrix
asphalt and the chlorinated paraffin are added, so that the overall performance ofthe
cold welding seam agent is improved; by adding the
fiber, the
mechanical property is improved, and the prepared cold
welding seam agent has good sliding performance and is easy to construct; by adding the
organic solvent, CoO.Co2O3, flocculant, stabilizer, cross-linking agent and 2-ethyl-4-methylimidazole for sufficient emulsification, the cold
welding seam agent has the advantages of higher
bonding strength, excellent elongation, higher
wear resistance, longer service life, favorable embeddability and favorable durability.
