Embodiment 1
[0036] While maintaining the system temperature at 15°C, disperse 3 parts of stearyl alcohol, 3 parts of lauryl stearate, and 4 parts of 70# microcrystalline wax into particles with a diameter of less than 1mm in a high-speed pulverizer to obtain solid mixture I;
[0037] Add 5 parts of 68# white oil, 10 parts of the solid mixture I obtained above, 0.3 parts of secondary alcohol polyoxyethylene ether (30), 0.3 parts of sodium lauryl phosphate and 10 parts of water into the ball mill, and keep the rotation speed at 200rpm Stir to form a solid-liquid mixture II that can be stirred;
[0038] Add balls with a diameter of 0.6~1.0mm and 0.1 part of defoamer to the above solid-liquid mixture II, keep the system temperature at 30±2°C, increase the speed to 1000rpm, grind for 10min; then add 13.5 parts of water to the system, Make the solid content of the dispersion liquid 40%, add balls with a diameter of 0.3~0.6mm, and continue grinding for 100min;
[0039] Finally, add the remainin...

[0041] While maintaining the system temperature at 18°C, disperse 20 parts of behenyl alcohol, 3 parts of pentaerythritol stearate, and 3 parts of paraffin into particles with a diameter of less than 1 mm in a high-speed pulverizer to obtain solid mixture I;
[0042] Add 26 parts of the solid mixture I obtained above, 1 part of branched chain secondary alcohol polyoxyethylene ether (20), 0.8 part of Pingpingjia O-25, 1.2 parts of NNO, and 15 parts of water into the ball mill, and keep stirring at 450 rpm , forming a solid-liquid mixture II that can be stirred;
[0043] Add balls with a diameter of 0.6~1.0mm and 0.3 parts of defoamer to the above solid-liquid mixture II, keep the system temperature at 20±2°C, increase the speed to 3000rpm, and grind for 25 minutes; then add 13.7 parts of water to the system, Make the solid content of the dispersion liquid 50%, add balls with a diameter of 0.3~0.6mm, and continue grinding for 40 minutes;
[0044] Finally, add the remaining 41 p...
Embodiment 3
[0046]While maintaining the system temperature at 10°C, disperse 10 parts of lauryl alcohol, 9 parts of stearyl palmitate, and 3 parts of rubber protective wax into particles with a diameter of less than 1 mm in a high-speed pulverizer to obtain solid mixture I;
[0047] Add 6 parts of alkylbenzene, 22 parts of the solid mixture I obtained above, 1.2 parts of octylphenol polyoxyethylene ether (30), 0.8 parts of AES and 15 parts of water into the ball mill, and keep stirring at 100 rpm to form a stirring The solid-liquid mixture II;
[0048] Add balls with a diameter of 0.6~1.0mm and 0.5 parts of defoamer to the above solid-liquid mixture II, keep the system temperature at 35±2°C, increase the speed to 5000rpm, and grind for 30 minutes; then add 14.5 parts of water to the system, Make the solid content of the dispersion liquid 50%, add balls with a diameter of 0.3~0.6mm, and continue grinding for 20 minutes;
[0049] Finally, the remaining 39.8 parts of water were added to the...
