| titleOfInvention | Brass artillery shell chromium-free environment-friendly type passivator and preparation method |
| abstract | The present invention discloses and a kind ofly both can ensure passivation quality and be beneficial to brass artillery shell chromium-free environment-friendly type passivator and the preparation method of environmental protection, raw materials used and mass percent is as follows: phytic acid 1 ~ 4%, oxalic acid 0.8 ~ 2%, Sodium Benzoate 1 ~ 8%, Sodium orthomolybdate 1 ~ 4%, trolamine 1 ~ 10%, benzotriazole 0.8 ~ 2.8%, potassium hydroxide 0.1 ~ 1%, industrial spirit 1 ~ 10% and water surplus.Prepare as follows: be first dissolved in the industrial spirit calculating and weigh for subsequent use by calculating the benzotriazole weighed; Again the water calculating weighing 1/2 is joined in reactor, start agitator; Then slowly join calculating the phytic acid, oxalic acid, Sodium Benzoate, Sodium orthomolybdate, potassium hydroxide, trolamine and the benzotriazole solution for subsequent use that weigh successively in reactor, be stirred to the transparent shape of solution, finally more remaining 1/2 water yield is added wherein, continue stirring 1 ~ 2 hour. |
