Abstract

The invention provides a stainless steel degreasing agent, which comprises the following components in percentage by weight: 5 to 25 percent of organic solvent, 2 to 5 percent of corrosion inhibitor, 10 to 25 percent of surfactant, 5 to 10 percent of inorganic salt, 1 to 3 percent of defoaming agent and the balance of deionized water, wherein the organic solvent is bromohydrocarbon; the corrosion inhibitor is sodium benzoate, ammonium benzoate, triethanolamine, ethanolamine or benzotriazole; the surfactant is one or more of alkylphenol polyoxyethylene ether and fatty alcohol-polyoxyethylene ether; the inorganic salt is alkaline salt; and the defoaming agent is tributyl phosphate, organic silicon, oleic acid or sodium oleate. The stainless steel degreasing agent can replace the currently used ODS cleaning agents, can achieve the cleaning effect of the ODS cleaning agents, does not damage the surface of the stainless steel, has obvious cleaning effect, can clean a large number of products, and does not harm a human body; and the preparation method is simple, safe, and environment-friendly.

Description

The stainless steel degreaser

Technical field

The present invention relates to a kind of degreaser, specifically, relate to a kind of stainless steel degreaser.

Background technology

Along with the development of modern society, steel industry has become the mainstay industry of country, lathe,

Processing industries such as workpiece are constantly risen, and a lot of workpiece material have changed Stainless Steel Products into by institute's material products.

And a large amount of machining oils, lubricating oil in the stainless steel course of processing, have unavoidably been adopted.And greasy dirt in stainless steel polishing in the employed buffing wax abrasive grains and machining oil can cause very big influence to the smooth finish on stainless steel work-piece surface.The stainless steel degreaser that relates among the present invention is exactly pollutents such as machining oil residual behind the stainless steel polishing, lubricating oil buffing wax particle.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art part, a kind of stainless steel degreaser is provided.

Stainless steel degreaser of the present invention comprises following integral part according to weight percent:

Organic solvent 5%～25%

Inhibiter 2%～5%

Tensio-active agent 10%～25%

Inorganic salt 5%～10%

Defoamer 1～3%

The deionized water surplus,

Wherein, said organic solvent is a hydrobromic ether; Said inhibiter is Sodium Benzoate, ammonium benzoate, trolamine, thanomin or benzotriazole; Said tensio-active agent is one or more in alkylphenol polyoxyethylene and the fatty alcohol-polyoxyethylene ether; Said inorganic salt are basic salt; Said defoamer is tributyl phosphate, organosilicon, oleic acid or sodium oleate.

Preferably,

Said hydrobromic ether is positive N-PROPYLE BROMIDE.

Said alkylphenol polyoxyethylene is polyoxyethylene nonylphenol ether or polyoxyethylene octylphenol ether.

Said fatty alcohol-polyoxyethylene ether is AEO-3, AEO-7 or AEO-9.

Said basic salt is caustic soda, yellow soda ash, sodium bicarbonate, sodium metasilicate, Starso, Sodium hexametaphosphate 99 or tripoly phosphate sodium STPP,

More preferably,

15% positive N-PROPYLE BROMIDE;

3% trolamine;

8% polyoxyethylene nonylphenol ether;

12% AEO-7;

8% sodium metasilicate;

1% tributyl phosphate;

53% deionized water.

Each composition has following effect among the present invention:

Characteristics such as 1) organic solvent: being hydrobromic ether, mainly is positive N-PROPYLE BROMIDE, and it is strong that the hydrobromic ether solvent has a high cleansing power of polarity, good with various material compatibilities, and surface tension is low are the best products that substitutes the ODS solvent;

2) inhibiter: mainly reaching when cleaning does not have the burn into not damaged to lens surface, cleans the effect that the back strengthens surface smoothness;

3) tensio-active agent: the surface tension that reduces solution is at first played in the adding of these a few class promoting agents, strengthens osmosis; In addition, have good degreasing power, and emulsifying effect, can play simultaneously and clean and soil-removing action;

4) inorganic salt: itself also be that a kind of clean-out system is widely used in the opticglass cleaning, and can be used as auxiliary agent, strengthen the surfactant washing ability, can strengthen scavenging solution stability in hard water and the residual lipid smeary dispersive ability of lens surface simultaneously;

The present invention has following technique effect:

(1) the present invention selects the collocation method of mixed solvent for use, will have organic solvent, inhibiter, tensio-active agent, inorganic salt, defoamer and water to mix and obtain the stainless steel degreaser.Because interactive result, the dissolving power of liquid is greatly improved, and the advantage of solvent is brought into play to greatest extent;

(2) organic solvent of the present invention's use mainly is a hydrobromic ether, is the choice solvent of the alternative ODS class material of at present environmental protection;

(3) select inhibiter for use among the present invention, not only strengthened the ability of saponification reflection, can also improve the character of clean-out system uniform corrosion erosion, and reduce the introducing of metal ion;

(4) added elite promoting agent among the present invention, can reduce the surface tension of liquid, the perviousness of enhance liquid has good degreasing power, and emulsifying effect, can play simultaneously and clean and soil-removing action;

(5) tensio-active agent of selecting for use among the present invention has advantages such as good water solubility, seepage force be strong, pollution-free;

(6) chemical reagent of selecting for use in the degreaser agent is free from environmental pollution, nonflammable, harmless, belongs to the non-material that damages the ozone layer, and satisfies environmental requirement.Can substitute the ODS clean-out system and halogenated hydrocarbon solvent and the strong basicity clean-out system that are still using at present.
