▎ 摘　　要

NOVELTY - Preparing heat preservation and sound insulation heat proof integrated spray mortar comprises (i) taking raw materials; (ii) adding river sand, silicate cement and insulating particles into a high-speed mixer for mixing at 105-110 degrees C under speed of155-170 revolutions/minute for40-50 minutes to obtain the mixture A; and (iii) adding mixture A, polyester fiber, cement foaming agent, sound modifier and nano graphene into a high-speed mixer for mixing under speed of 1300-1400 revolutions/minute for 60-70 minutes, where the spray mortar includes 16 pts. wt. silicate cement, 2 pts. wt. insulating particles, 2 pts. wt. polyester fiber, 1 pts. wt. cement foaming agent, 3 pts. wt. sound modifier and 6 pts. wt. nano graphene. USE - The method is useful for preparing heat preservation and sound insulation heat proof integrated spray mortar. ADVANTAGE - The method improves building strength; and is simple with easily available raw materials and convenient.
