Embodiment 1
[0044]Add 8 parts of co-solvent CO-2 and 1 part of hydrophobic particles D10 (provided by Evonik, specific surface area 90 m 2 / g) Pre-dispersion R was obtained at 120°C for 1.5h at a rotational speed of 70rpm;
[0045] At room temperature, add 84 parts of 15# white oil, 1 part of hydrophobic particles (R974, provided by Evonik, specific surface area 170m 2 / g), 1 part of hydrophobic particles (DS380, provided by Evonik, specific surface area 380m 2 / g), 5 parts of emulsifying dispersant PEG 600DO are dispersed and ground at a speed of 2000 rpm, so that the particle size D90 of hydrophobic particles is controlled below 5 μm, and then the above-mentioned predispersion R, 1 part of lauryl oleate, 4 parts of leveling agent L-3, and finally stirred at 1000rpm for 45 minutes to ensure uniform dispersion of particles, that is, the patented mineral oil-based foam control composition FC-1.
Embodiment 2
[0047] Add 5 parts of co-solvent CO-4 and 1 part of hydrophobic particles (treated with methyltrichlorosilane, specific surface area 220m 2 / g) Pre-dispersion R was obtained by incubating at 190°C for 3 hours at a rotational speed of 150rpm;
[0048] At room temperature, add 50.5 parts of base oil 120N, 18 parts of 15# white oil, 3 parts of hydrophobic particles (H2000, provided by Evonik, specific surface area 150m 2 / g), 3.5 parts of hydrophobic particles (treated with hexamethylsilazane, self-made, specific surface area 380m 2 / g) and 7 parts of emulsifying dispersant EL-12 are dispersed and ground at a speed of 1000 rpm, so that the particle size D90 of the hydrophobic particles is controlled below 5 μm, and then the above-mentioned predispersion R and 3 parts of stearic acid stearic acid are added to it Alcohol ester, 9 parts of leveling agent L-2, and finally stirred at 550rpm for 60 minutes to ensure uniform dispersion of particles, that is, the patented mineral oil-ba...
Embodiment 3
[0050] Add 2 parts of co-solvent CO-1 and 0.5 parts of hydrophobic particles (H18, Wacker, specific surface area 120m 2 / g) Pre-dispersion R was obtained by incubating at 80°C for 40min at a rotational speed of 100rpm;
[0051] At room temperature, add 35.5 parts of liquid wax, 44 parts of 5# white oil, 1.5 parts of hydrophobic particles (HL200, provided by Jibisheng Company, treated with hexamethyldisiloxane, specific surface area 200m 2 / g), 3 parts of hydrophobic particles (DS380, specific surface area 380m 2 / g) and 9 parts of emulsifying dispersant isomeric tridecyl alcohol polyoxyethylene ether (10) are dispersed and ground at a speed of 3000 rpm, so that the particle size D90 of the hydrophobic particles is controlled below 5 μm, and then the above-mentioned pre-dispersion is added to it R, 1.5 parts of oleic acid, 6 parts of leveling agent L-4, and finally stirred at 1500rpm for 22 minutes to ensure uniform dispersion of particles, that is, the patented mineral oil-ba...
