Wherein the content of the first and second substances,
in the step (1), the hot mixing time in the hot mixing machine is 600-900s, and the blanking is started and discharged into the cold mixing machine when the hot mixing temperature reaches 120-125 ℃; the cold mixing time in the cold mixer is 300-400s, and the blanking is started when the cold mixing temperature reaches 42-45 ℃.
