Embodiment 1
[0023] Raw materials: polyvinyl alcohol 1788 13%, alkyl glycoside APG1214 8%, alkylphenol polyoxyethylene ether OP-10 7%, benzotriazole 0.8%, triethanolamine oleic acid soap 2%, ethanol 14%, detox Ionized water 55.2%.
[0024] The preparation method is as follows:
[0025] (1) Take the raw material by weighing the raw material formula;
[0026] (2) Dissolving polyvinyl alcohol 1788 in ethanol and stirring for 30 minutes to obtain the first solution;
[0027] (3) Add alkyl glycoside APG1214, alkylphenol polyoxyethylene ether OP-10, benzotriazole, and triethanolamine oleic acid soap to deionized water in sequence, and stir for 50 minutes to obtain the second solution;
[0028] (4) Mix the two solutions obtained in step (2) and step (3), and stir for 30 minutes to obtain a metal welding base metal protective agent, which is filled into an aerosol can.
