Abstract
The invention discloses an environment friendly acid pickling rust remover which comprises the following raw materials in mass percent: 16-26% of citric acid, 5-10% of oxalic acid, 5-10% of methanesulfonic acid, 0.5-1.5% of 50% phytic acid, 0.1-0.5% of sodium monofluorophosphate, 0.5-1.5% of EDTMP, 3-6% of BR516, 0.5-1.5% of QYL-210F, 0.5-1.5% of JFC and the balance of water. A preparation method of the environment friendly acid pickling rust remover comprises the following steps: adding calculated and weighed water into a reaction still, starting a stirrer, controlling the revolving speed of the stirrer to be 30-40 rpm, sequentially and slowly adding calculated and weighed citric acid, oxalic acid, methanesulfonic acid, phytic acid, sodium monofluorophosphate, organic acid pickling assistant, EDTMP, acid degreasing derusting surfactant and JFC into the reaction still in a stirring manner until the solution becomes tiny citrine transparent liquid.
Description
Technical field
The present invention relates to the agent of a kind of environment-friendly type acid pickling and rust removing and preparation method, the environment-friendly type acid pickling and rust removing agent clean-out system that especially a kind of environmental safety is good and preparation method.
Background technology
Metal cleaning is metal products requisite process procedure before the precision work such as spraying, plating.Full automatic line pretreatment technology before existing electrophoretic painting is as follows: and drill traverse sprays pre-degreasing → drill traverse spray degreasing → drill traverse spray washing → drill traverse acid pickling and rust removing → drill traverse spray washing → drill traverse spray neutralization → drill traverse spray washing → drill traverse spray table tune → drill traverse and sprays phosphatization → drill traverse spray washing → drill traverse pure water and washes → and drill traverse pure water washes → electrophoretic painting.Drill traverse acid pickling and rust removing wherein substantially adopts hydrochloric acid to add inhibiter and processes, and the strong and pungent road of hydrochloric acid corrosion resistance, not only operating process causes environmental pollution, and the cost of follow-up liquid waste disposal is higher.
Summary of the invention
The present invention is the above-mentioned technical problem in order to solve existing for prior art, the environment-friendly type acid pickling and rust removing agent providing a kind of environmental safety good and preparation method.
