Step (3): diatomite 5-10 part, Calcium Fluoride (Fluorspan) 10-15 part, saltcake 10-15 part are carried out grinding in pulverizer, rotating speed is 100r/min, grinding 3 hours, obtaining compound particles granularity size is 0.6-0.8mm, heats afterwards to grinding thing, Heating temperature 700 DEG C, be incubated 2 hours, after cooling in pulverizer grinding 3 hours again, obtaining mixture B granularity size is 0.3-0.5mm
Step (4): step (2) is obtained mixture A and step (3) is obtained mixture B loading in mechanical mixer, mechanically mixing 0.5 hour, pour polyvinyl alcohol 3-4 part, sodium-acetate 3-4 part, sodium carbonate 1-3 part afterwards into, gypsum 2-4 part, water glass 2-3 part, aluminium powder 1-2 part, calcium chloride 1-2 part, mechanically mixing 1 hour again, obtaining take dickite as the mineral additive of main raw material.
2. be the preparation method of the mineral additive of main raw material as claimed in claim 1 with dickite, it is 0.9mm that step (2) obtains mixture A granularity size.
3. be the preparation method of the mineral additive of main raw material as claimed in claim 1 with dickite, it is 0.4mm that step (3) obtains mixture B granularity size.
4. be the preparation method of the mineral additive of main raw material as claimed in claim 1 with dickite, diatomite composition is (weight): 80.2%SiO2,5.7%Al2O
3, 0.68%Fe2O
3, 1.1%CaO, 1.62%MgO, 10.7% loss on ignition.
5. be the preparation method of the mineral additive of main raw material as claimed in claim 1 with dickite, dickite composition is (weight): 61.1%SiO
2, 31.3%Al2O
3, 1.2%Fe2O
3, 1.1%CaO, 0.5%MgO, 4.8% loss on ignition.
