Embodiment 1

[0023] An environment-friendly metal surface degreasing and rust removing agent comprises the following components (by mass percentage):

[0024] Citric Acid: 22%, Ferric Hydroxide: 5%, Glycerin: 3%, Phenol: 4%, Sodium Lactate: 4%, Oxalic Acid: 1.5%, Tartaric Acid: 2.5%, Paraben: 8%, Emulsifier: 11%, defoamer: 14%, ammonium bicarbonate: 1%, and the balance is water.

[0025] Wherein, the emulsifier is Triton X-100, that is, octoxynol; the defoamer is any one or a mixture of polyether silicone oil defoamers and silicone oil emulsion defoamers.

Embodiment 2

[0027] An environment-friendly metal surface degreasing and rust removing agent comprises the following components (by mass percentage):

[0028] Citric Acid: 23%, Ferric Hydroxide: 4%, Glycerin: 5%, Phenol: 3%, Sodium Lactate: 5%, Oxalic Acid: 1%, Tartaric Acid: 3%, Paraben: 6%, Emulsifier: 12%, defoamer: 13%, ammonium bicarbonate: 2%, and the balance is water.

[0029] Wherein, the emulsifier is Triton X-100, that is, octoxynol; the defoamer is any one or a mixture of polyether silicone oil defoamers and silicone oil emulsion defoamers.

Embodiment 3

[0031] An environment-friendly metal surface degreasing and rust removing agent comprises the following components (by mass percentage):

[0032] Citric Acid: 24%, Ferric Hydroxide: 3%, Glycerin: 7%, Phenol: 2%, Sodium Lactate: 6%, Oxalic Acid: 0.5%, Tartaric Acid: 3.5%, Paraben: 4%, Emulsifier: 13%, defoamer: 12%, ammonium bicarbonate: 3%, and the balance is water.

[0033] Wherein, the emulsifier is Triton X-100, that is, octoxynol; the defoamer is any one or a mixture of polyether silicone oil defoamers and silicone oil emulsion defoamers.

[0034] The environment-friendly metal surface degreasing and rust removing agents can be prepared through the above three groups of embodiments, and the metal surface degreasing and rust removing agents prepared in the second group of embodiments have the best effect. The metal degreasing and derusting agent prepared by the invention has a simple process, can degrease and derust the metal surface at the same time, reduces the investmen...

Abstract

The invention discloses an environment-friendly metal surface oil removal rust remover, which relates to the technical field of metal surface treatment. The environment-friendly metal surface oil removal rust remover is characterized by comprising the following ingredients (by weight percent): 22 to 24 percent of citric acid, 3 to 5 percent of iron hydroxide, 3 to 7 percent of glycerinum, 2 to 4 percent of phenol, 4 to 6 percent of sodium lactate, 0.5 to 1.5 percent of oxalic acid, 2.5 to 3.5 percent of tartaric acid, 4 to 8 percent of 4-methoxyphenol, 11 to 13 percent of emulsifier, 12 to 14percent of defoaming agent, 1 to 3 percent of ammonium bicarbonate, and the balance of water. The metal oil removal rust remover prepared in the invention is simple in procedures, capable of simultaneously removing the oil and rust on the metal surface, capable of reducing the procedures and equipment investment, free from phosphoric acid, free from discharging phosphorus-containing substance polluting the water source, safe, environment-friendly, free from irritating smell, noncorrosive to the skin and clothes, and stable in performance.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to an environment-friendly metal surface oil and rust remover. Background technique [0002] Rust removal treatment is the basic process before metal surface painting. The existing rust removal methods can be roughly divided into three categories: mechanical, chemical and electrochemical methods, each of which has its own characteristics and is suitable for different occasions. Among them, the chemical method has a series of advantages such as good effect, high efficiency, simple process operation, and low cost, so it has been widely used in industry. However, the traditional acid treatment method also has obvious defects: that is, the generation of a large amount of hydrogen during the treatment process will cause hydrogen embrittlement of the steel and affect the strength of the steel itself; at the same time, it is easy to form acid mist, which will affect the he...
