Embodiment 1

[0019] A multifunctional environment-friendly metal degreasing, rust-removing and rust-preventing liquid is special in that it is prepared from the following components (amounts are in parts by weight).

[0020] Polyoxyethylene alkyl ether 1 Sodium dodecyl sulfonate 1

[0021] 1.3-Dibutylthiourea 0.5 Hexamethylenetetramine 0.5

[0022] Zinc dihydrogen phosphate 1 Phosphoric acid 10

[0023] water 20

[0024] Weigh the above-mentioned raw materials in proportion, dissolve the solid into a solution with water, dilute the liquid, then put each raw material into the reaction kettle, stir for 15-30 minutes, and filter with 120-mesh gauze to make the finished product. The water temperature is 25°C.

Embodiment 2

[0026] Polyoxyethylene alkyl ether 4 Sodium dodecyl sulfonate 5

[0027] 1.3-Dibutylthiourea 6 Hexamethylenetetramine 3

[0029] Sodium butylnaphthalene sulfonate 3 Sodium succinate sulfonate 3

[0030] Triethanolamine 5 Sodium bicarbonate 3

[0031] Tartaric acid 7 1.3-Diethylthiourea 5

[0032] water 50.

[0033] Weigh the above-mentioned raw materials in proportion, dissolve the solid into a solution with water, dilute the liquid, then put each raw material into the reaction kettle, stir for 15-30 minutes, and filter with 120-mesh gauze to make the finished product. The water temperature is 50°C.

Embodiment 3

[0035] Polyoxyethylene alkyl ether 6 Sodium dodecyl sulfonate 8

[0036] 1.3-Dibutylthiourea 10 Hexamethylenetetramine 5

Abstract

The functional environment friendly metal deoiling, derusting and antirusting fluid is prepared with polyoxyethylene alkyl ether, sodium dodecyl sulfate, 1.3-dibutyl thiourea, hexamethylidyene tetraamine, zinc dihydrogene phosphate, phosphoric acid, sodium butylnaphthalene sulfonate, sodium sulfosuccinate, triethanolamine, sodium bicarbonate, tartaric acid and 1.3-diethyl sulfourea in certain weight proportion, and through dissolving, diluting with water, mixing to react, and filtering. It has the synergistic effect of the components to deoil, derust, phosphorize, deactivate and antirust metal surface, no harm to human body and no environmental pollution.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a degreasing and descaling fluid for surface pretreatment of metal materials and their products. Background technique [0002] At present, in the existing technology, the degreasing and derusting of the metal surface basically use artificial, physical and chemical methods. Product quality, and produce a lot of dust, pollute the environment, endanger the health of workers; physical derusting, mainly ultrasonic degreasing and derusting effect, due to the large investment, the scope of application is not universal; chemical degreasing and derusting is the most effective method for metal surface treatment The common and most economical method, the traditional degreasing is to use strong alkali NaOH and tetrachlorethylene, rust removal with strong acid such as HCl and H 2 SO 4 These raw materials are highly corrosive and irritating substances, which can cause serious...
