(2) by above-mentioned Ca (OH)2Two parts of the weight such as suspension is divided into, a copy of it adds b diammonium edta, magnesium chloride, the sodium phosphate trimer, 1 of above-mentioned weight portion, and two (triethoxy the is silica-based) ethane of 2-, moves in carbonization reactor after stirring, and passes into from CO2The pure CO of steel cylinder2With the air from air compressor machine, be mixed into containing volume fraction 25-30%CO2Gas react, in the time of pH=6.5-7.0, stop reaction, add above-mentioned sorbitan monooleate, stir to obtain a liquid;
(3) another part of Ca (OH)2Suspension adds the aminopropyl triethoxysilane of above-mentioned weight portion, and agitating heating 20-30 minute at 90-110 DEG C, obtains b liquid;
(4) stearic acid of above-mentioned weight portion is heated to 60-70 DEG C, adds ethoxylated dodecyl alcohol, the peregal o of above-mentioned weight portion, rising temperature is as for 80-85 DEG C, constant temperature stirs 1-2 hour, under stirring condition, slowly add above-mentioned b liquid, after interpolation, continue to stir 1-2 hour, obtain c material;
(5) a material, c are expected to mix, add the each raw material of residue, high speed 1500-2000 rev/min of centrifugal mixer 20-30 minute, dries, and is ground into superfines, is described modifier.
