Embodiment 1
[0040] This embodiment provides a dicyclopentadiene and / or dicyclopentadiene derivative polymer modified asphalt and a preparation method thereof, the steps are as follows:
[0041] First put 100 parts of petroleum asphalt into 135°C for drying, put it into a heating mantle and cool it to 110°C, then start stirring; prepare 20 parts of kerosene, and slowly add it to the petroleum asphalt; stir until it is uniform, then place In the state of normal temperature, let it cool down, and component A can be obtained.
[0042] Put dicyclopentadiene and / or dicyclopentadiene derivatives into 30-40°C for heating and heat preservation to dissolve, take 75 parts of dicyclopentadiene and / or dicyclopentadiene derivatives, add 20.99 parts of kerosene, and wait until fully stirred , add 1 part of triphenylphosphine and stir slightly, then add 0.01 part of grubbs2 generation catalyst, and stir evenly at room temperature to obtain component B.
[0043] Then get 92 parts of component A and 100 p...
Embodiment 2
[0045] This embodiment provides a dicyclopentadiene and / or dicyclopentadiene derivative polymer modified asphalt and a preparation method thereof, the steps are as follows:
[0046] First put 100 parts of petroleum asphalt into 135°C for drying, put it in a heating mantle and cool it to 110°C, then start stirring; prepare 20 parts of gasoline, and slowly add it to the base asphalt; stir until it is uniform, then place In the state of normal temperature, let it cool down, and component A can be obtained.
[0047] Put dicyclopentadiene and / or dicyclopentadiene derivatives into 30-40°C to heat and heat-preserve to dissolve, take 90 parts of dicyclopentadiene and / or dicyclopentadiene derivatives, add 8.99 parts of kerosene, and wait until fully stirred , add 4 parts of triphenylphosphine and stir slightly, then add 0.01 part of grubbs2 generation catalyst, and stir evenly at room temperature to obtain component B.
[0048] Then take 126 parts of component A and 60 parts of compon...
