Sieve, the insulation filler after being acidified is standby；
（2）, prepare plaster of Paris
Desulfurated plaster is weighed, drying baker is put into, 1 ~ 3h is pre-processed under 60 ~ 70 DEG C of hot conditions, then takes out and is put into calcining furnace,
In 120 ~ 160 DEG C of temperature lower calcinations, whole free waters and partially crystallizable water are sloughed, semi-hydrated gypsum is formed and a small amount of II types is anhydrous
Gypsum；Then sintering desulfuration gypsum is placed on room temperature, under unlimited environment after storage 6~8 days, crosses 100 ~ 120 mesh sieves, built
Gypsum is built, it is standby；
（3）, prepare modified building gypsum
Weigh step（1）Insulation filler and step after processing（2）Obtained plaster of Paris, adds electricity thereto after mixing
Rock ballast and grinding aid, are put into ball mill and wear into fine powder, cross 150 ~ 180 mesh sieves, are then calcined under 160 ~ 175 DEG C of hot conditions
Modified building gypsum is obtained after 1 ~ 2h, cooling, it is standby；
（4）, weigh glutinous rice glue, nano whisker exciting agent and water according to proportioning, add step（3）Obtained modified building gypsum
In, after being uniformly mixed, boiling in steam stove is placed in, temperature control is 90 ~ 160 DEG C, and the time is 1~2h, obtains slurry, standby
With；
（5）, weigh surplus stock according to proportioning, add step（4）In obtained slurry, mixed with 300 ~ 400r/min rotating speed
Uniformly, mixed material is obtained, is 6 ~ 10% by the moisture control of mixed material；
（6）, by step（5）Obtained mixed material is placed in extruding in double screw extruder, strip of growing up, and is placed in mass fraction
In 0.5 ~ 1mol/L watery hydrochloric acid, to carry out pickling, the spot of strip-like surface is removed, and by after its natural air drying 4~5 days, is obtained
To dry mixed material, dry mixed material is ground into powder by airslide disintegrating mill, the environmental protection is produced and paints stone
Cream.
