Jarring formula vibrating sieving machine obtains the ardealite powder that diameter is less than 5mm, and 60 DEG C drying to constant weight, with m (ardealite)：M (quick lime)：
M (water)=100:5:15 ratio is mixed evenly after weighing, and ageing for 24 hours, after ageing, is placed in baking oven at 150 DEG C
Beta-type semi-hydrated gypsum is obtained for 24 hours；Ardealite is placed in still kettle 5h at 140 DEG C, dries to obtain ɑ types half after being cooled to room temperature in 100 DEG C
Beta-type semi-hydrated gypsum is mixed with ɑ type semi-hydrated gypsums, pulverizes, obtain building gypsum by water gypsum.
Preferably, the modified pulp starch is produced by ative starch by pre- sludging process, then modified processing obtains,
Wherein, the ative starch is selected from one or more of cornstarch, tapioca, potato starch, the modification choosing
Autoxidation is modified, the method for cross-linking modified, esterification modification or graft modification.
Preferably, the re-dispersible glue powder is ethene-vinyl acetate combined polymerization species, polyvinyl alcohol, polyethylene
Class, methylcellulose or poly- Propionamides.
Preferably, the inorfil is in alumina silicate fibre, brucite fiber, slag wool fiber, sepiolite fibre
Any one.
Preferably, the granularity of the closed-cell expanded perlite is 40-60mu, bulk density 60-80kg/m3, lead
