[0018] The preparation method of the one-step car cleaning glazing agent of the present invention, according to the mass ratio: take 100 parts of water, 0.1-3 parts of montan wax, 0.5-5 parts of paraffin, 10-25 parts of cyclohexane or ethyl acetate, and 0.3 parts of Siban -2 parts, 0.3-2 parts of Tween, 0.5-10 parts of sodium dodecylbenzenesulfonate, 0.5-5 parts of nano silicon dioxide; the preparation steps are as follows:
[0019] a. First put montan wax and paraffin into cyclohexane or ethyl acetate in portions, heat and reflux in the reactor for 10 minutes, and allow the montan wax and paraffin to fully dissolve in the solvent to obtain a wax solution;
[0020] b. Add Span and Tween, stir evenly to obtain a mixed solution;
[0021] c. After sodium dodecylbenzene sulfonate is made into an aqueous solution with a content of 0.5-1.0%, slowly add it to the mixed solution with the temperature of the system lowered by no more than 5°C, and stir while adding, maintaining the same...

[0026] According to the mass ratio: put 1 part of montan wax and 2 parts of paraffin into 15 parts of cyclohexane or ethyl acetate as a solvent, and heat it under reflux in the reaction kettle for 10 minutes, so that the montan wax and paraffin are fully dissolved in the solvent to obtain a wax solution Then turn on the agitator with a stirring rate of 250r / min, add 0.6 parts of Span 80 and 1.2 parts of Tween 80 into the wax solution, and stir evenly. In another container, dissolve 0.6 parts of sodium dodecylbenzenesulfonate in 100 parts of water; slowly add the aqueous solution of sodium dodecylbenzenesulfonate into the wax solution, maintain the same stirring speed, and It is advisable to lower the temperature by no more than 5°C, and emulsify at 90°C for 50 minutes. After the treatment, add 3 parts of nano silicon dioxide into the emulsion and stir evenly, and the obtained emulsion is the cleaning and polishing agent. .
