The invention discloses a preparation method of inorganic heat preservation paste, comprising the following steps: S1, putting
polypropylene cellosilk into a water vat, scattering, adding into a pullvat, adding a proper amount of water into the pull vat, putting the pull vat under a stirrer, stirring, controlling a head of a stirring
paddle to approach the bottom of the pull vat, adding an aid, aperformance additive and
mica powder in sequence during stirring, supplementing a proper amount of water, and continuously stirring; S2, adding glass beads into the pull vat, stirring, and increasingthe height of the
paddle; putting floating beads, paste beads and horn
meal into the pull vat in sequence, supplementing a proper amount of water, and stirring until a dry
mass disappears; S3, lowering the head of the stirring
paddle to approach the bottom of the pull vat, shoveling off materials remaining inside the pull vat, continuously stirring, supplementing a proper amount of water, stirring, supplementing a proper amount of water, and continuously cleaning an edge; S4, pulling the pull vat to be below a lifter, lifting, pouring into a packing bag, weighing, sealing, sewing a pack, andwarehousing after inspection.
