Abstract

The invention discloses an automobile paint surface cleaning and repairing agent and a preparation method thereof. The selected components of the cleaning and repairing agent include nonionic surfactant fatty alcohol polyoxyethylene ether, corrosion inhibitor oleic acid diethanolamide borate, excipient Forming agent sodium alginate, wax removing agent xylene, purifying agent dimethylformamide, defoaming agent dimethyl silicone oil, diluent composed of various organic solvents and self-repairing filler developed by ourselves, through mixing and stirring, vacuum removal Prepared by stirring. The cleaning and repairing agent of the present invention is sprayed on the scratches of the car, does not damage the car paint, and is compatible with the varnish on the car surface. After it automatically fills up the scratch pits and forms a film, no obvious stains and scratches can be seen with the naked eye. No scratches, no damage to the car paint, one-time cleaning and repair of the car paint surface, saving the cost of repairing car scratches and construction costs.
