Embodiment 1
[0019] The preparation method of non-stick wheel emulsified asphalt for adhesive layer of the present invention, the steps are as follows:
[0020] (1) Heat 100 parts of Shuanglong 70# asphalt to 175°C, turn on the shearing machine, then add 3.5 parts of SBS and 3 parts of polyethylene wax with a melting point of 99°C to Ssangyong 70# asphalt and shear Cut for 1 hour, add 2 parts of Kelian YT-6 rubber oil after the cutting is completed, and after the temperature rises to 175°C, slowly add 0.3 parts of sulfur, and stir for 5.5 hours after the addition is complete to prepare the parent asphalt.
[0021] (2) Heat the parent asphalt to 165°C, then add 25 parts of sulfonated asphalt powder and 10 parts of rosin resin to the parent asphalt, and stir for 4 hours to prepare the modified asphalt.
[0022] (3) Add 0.45 parts of Aksu 4819 and 0.01 parts of sodium carboxymethylcellulose to 100 parts of water and stir until completely dissolved, then use 0.2 parts of 37% concentrated hydro...
