The invention relates to the technical field of building
coating production, and discloses a preparation process of a high-temperature-resistant fireproof
coating for a building. The preparation process comprises the following steps: mixing
solid raw materials,
grinding in a disc type grinder, screening with a 40-mesh
sieve, adding the mixture obtained in the step 1 into a stirring
barrel, injecting 20-30 parts of 40-60 DEG C
warm water, stirring, and mixing, stirring for 2 hours at the rotating speed of 900-1500
revolutions per minute; sequentially adding a
potassium silicate solution, a
thickening agent,
emulsion, a suspending agent, a curing agent, a drier and glue, stirring for 0.5 hours at the rotating speed of 80-100 rpm to obtain the corresponding
coating. The invention provides a preparation device of the high-temperature-resistant fireproof coating for the building. The preparation device comprises a stirring
barrel and a rotating stirring shaft arranged in the stirring
barrel, the stirring shaft is coaxially and fixedly connected with stirring support, a plurality of connecting rods for mounting stirring rods are distributed on the circumferential surface of the stirringsupport in a circumferential array manner, and rotating
brush seats for cleaning are arranged in the stirring rods, so that stirring and cleaning functions are achieved, and the cleaning efficiency isimproved.
