Example Embodiment
[0017] Example 1
[0018] Step 1: Turn on the mixer, raise the mixer temperature to 150°C, and take 3 parts of 10# asphalt, 50 parts of 70# asphalt, 12 parts of mineral oil, and 3 parts of styrene-butadiene-styrene block copolymer by weight. , 4 parts of styrene-butadiene rubber, 5 parts of polypropylene particles, after stirring for 30min, the temperature was raised to 190℃ and kept for 3h;
[0019] Step 2: reduce the temperature to 170°C, add 8 parts of flame retardant, 3 parts of antimony trioxide, 8 parts of 2-hydroxy-4-methoxybenzophenone, 10 parts of ultrafine talc, and stir for 1 hour;
[0020] Step 3: The mixture of Step 2 was cyclically ground in a colloid mill for 3 hours, cooled to 150°C, and then discharged.
