[0029] The present invention also provides a preparation method of an oil and rust remover, the specific steps comprising:
[0030] (1) Add 20-30 parts of water into the reaction kettle and raise the temperature to 40-60°C;
[0031] (2) Put 20-30 parts of HEDP in a beaker, slowly add 0.5-3 parts of tartaric acid, mix well; then slowly add 0-1 part of sodium pyrophosphate, stir well; then slowly add 0-10 parts of zinc lactate, Stir evenly; then slowly add 0-10 parts of sodium citrate, stir evenly; slowly add 0-10 parts of oxalic acid, stir well, and form a uniform solid mixture;
[0032] (3) Slowly add the solid mixture in step (2) to the warm water in step (1), 1000-3000 rpm, and stir evenly for 20-30 minutes;
[0033] (4) Dissolve 1-10 parts of corrosion inhibitor at 40-80°C and mix well;
[0034] (5) Pour the solution of step (4) into the solution of step (3), add 1-5 parts of penetrant, 1-5 parts of surfactant, 1000-3000 rpm, stir evenly for 20-30 minutes, That is, a liq...
