Embodiment 1

[0007] The raw materials and mass percentages used are as follows: 8% phosphoric acid with a mass percentage concentration of 85%, 1% citric acid, 2% potassium sodium tartrate, 1% sodium dihydrogen phosphate, 1.5% ethylene glycol monobutyl ether, special surface for immersion degreasing and degreasing Active agent 0.1%, carbon deposit removal surfactant 0.6%, wax removal water special surfactant 0.1%, penetrating agent JFC 1% and water balance.

[0008] The production method is carried out according to the following steps: add the calculated and weighed water into the reaction axe, start the mixer at a speed of 80 rpm, and then sequentially add the calculated and weighed phosphoric acid, citric acid, potassium sodium sulfate, sodium dihydrogen phosphate, ethyl Glycol monobutyl ether, special surfactant for soaking degreasing and oil removal, carbon deposit removal surfactant, special surfactant for wax removal water and penetrating agent JFC are added to the reaction axe, conti...

Embodiment 2

[0011] The raw materials and mass percentages used are as follows: 4% phosphoric acid with a concentration of 85% by mass, 2% citric acid, 1% sodium potassium tartrate, 3% sodium dihydrogen phosphate, 0.1% ethylene glycol monobutyl ether, special surface for immersion degreasing and degreasing Active agent 0.6%, carbon deposit removal surfactant 0.1%, wax removal water special surfactant 0.6%, penetrant JFC 0.5% and water balance.

[0012] Raw material source and production method are with embodiment 1.

Embodiment 3

[0014] The raw materials and mass percentages used are as follows: 6% phosphoric acid with a mass percentage concentration of 85%, 1.5% citric acid, 1.5% potassium sodium tartrate, 2% sodium dihydrogen phosphate, 1% ethylene glycol monobutyl ether, special surface for immersion degreasing and degreasing Active agent 0.4%, carbon deposit removal surfactant 0.4%, wax removal water special surfactant 0.4%, penetrant JFC 0.8% and water balance.

[0015] Raw material source and production method are with embodiment 1.

[0016] When in use, put the stock solution of Example 1, 2 or 3 of the present invention in a plastic pressure watering can, spray it evenly on the surface of the zinc-iron alloy plate workpiece, place it for 10-20 minutes, and then spray and clean it, which can completely remove the zinc-iron alloy plate workpiece Deep oil seepage.

Abstract

The invention discloses a deep oil leakage acid stripping agent before Zn and Fe alloy sheet material workpiece spray cleaning, the deep oil leakage acid stripping agent comprises the following raw materials: by mass, 4-8% of phosphoric acid with a concentration of 85%, 1-2% of citric acid, 1-2% of potassium sodium tartrate, 1-3% of sodium dihydrogen phosphate, 0.1-1.5% of ethylene glycol monobutyl ether, 0.1-0.6% of a soaking degreasing oil cleaning special surfactant, 0.1-0.6% of a carbon deposition removing surfactant, 0.1-0.6% of a wax solvent special surfactant, 0.5-1% of penetrating agent JFC and the balance of water. Before spray cleaning, the deep oil leakage acid stripping agent is in advance sprayed on to workpiece surface by an artificial plastic pressure watering can, after 10-20min of placing, a workpiece is hung onto a pretreatment automatic spray line, then deep oil leakage on a Zn and Fe alloy sheet material workpiece can be quickly and completely stripped to meet the technical requirements of spray painting.

Description

technical field [0001] The invention relates to a zinc-iron alloy plate workpiece deep-layer oil seepage acid stripper, in particular to a zinc-iron alloy plate workpiece deep oil seepage acid stripper before spraying and cleaning, which can quickly and thoroughly peel off the deep oil seepage of the zinc-iron alloy plate workpiece. Background technique [0002] During the rolling process of the zinc-iron alloy plate workpiece, a large amount of anti-rust oil will seep into the deep interior, so it needs to be sprayed and degreased before spraying. However, despite two spray cleaning and degreasing, the deep oil seepage still cannot be removed completely. Contents of the invention [0003] The present invention aims to solve the above-mentioned technical problems existing in the prior art, and provides an acid stripping agent for deep oil seepage of zinc-iron alloy plate workpieces before spraying and cleaning, which can quickly and thoroughly strip zinc-iron alloy plate w...
