Embodiment 1
[0041] refer to Figure 1-2 As shown, a kind of automotive paint polishing agent of the present embodiment comprises the following raw materials in parts by weight, 18 parts of hydrophobic repairing abrasives, 15 parts of fatty alcohol polyoxyethylene ether, 9 parts of simethicone oil, 6 parts of sodium alginate, 4 parts of potassium sorbate, 2.8 parts of compound brightener, 76 parts of diluent. The diluent is made by mixing and stirring acetone, ethyl acetate, toluene, and cyclohexane according to the mass ratio of 3:2:1:1.
[0042] Wherein, the preparation method of hydrophobic repair abrasive comprises the following steps:
[0043] 1) In parts by weight, add 35 parts of mesoporous silica to 180 parts of deionized water, stir slowly for 16 minutes to obtain a mesoporous silica dispersion, raise the temperature to 115°C, add 20 parts of attapulgite, and vacuum- Stir at 0.15MPa for 25min to obtain a silica mixture;
[0044] 2) In parts by weight, 8 parts of multi-walled ca...
