Abstract

The invention discloses an energy-saving and environment-friendly micro-emulsion cutting fluid, and belongs to the field of metal cutting lubricants. The micro-emulsion cutting fluid consists of the following components: 15 to 25 percent of mineral oil, 3 to 10 percent of extreme pressure anti-wear agent, 7 to 10 percent of mixed alcohol amine, 0.2 to 0.5 percent of non-ferrous metal antirust agent, 4 to 6 percent of boric acid, 8 to 12 percent of anionic surfactant, 5 to 12 percent of sulfonate antirust agent, 1 to 5 percent of alcohol type coupling agent, 4 to 6 percent of nonionic surfactant I, 5 to 7 percent of nonionic surfactant II, 0.5 to 1.5 percent of emulsification regulator, 0.5 to 2 percent of bactericide, 0.1 to 0.3 percent of anti-foaming agent, and the balance of deionized water. The micro-emulsion cutting fluid has the advantages that emulsified particles are small and stable, the oil-containing ratio is greatly reduced, the anti-rust property of the micro-emulsion cutting fluid is superior to that of emulsified cutting fluid, and the micro-emulsion cutting fluid does not contain chlorine and nitrite; and after the waste fluid is subjected to simple oil separation treatment, residues in the water can be biodegraded, so that environment friendliness and energy conservation are facilitated.

Description

A kind of energy saving and environment friendly micro-emulsion cutting fluid

Technical field

The present invention relates to a kind of energy saving and environment friendly micro-emulsion cutting fluid, belong to metal cutting lubricant field.

Background technology

Stainless steel coolant generally comprises water-base cutting fluid and oil base cutting fluid.Oil base cutting fluid poor radiation is cleaned trouble; Water-base cutting fluid comprises oil-in-water type, complete synthesis type, and water-base cutting fluid is little to environmental influence, and performance is more stable, but oilness is relatively poor; In addition, the rust cleaning composition comprises nitrite in most of cutting fluid, belongs to high carcinogenic substance, and emulsified cutting fluid is short work-ing life.

Summary of the invention

In view of the defective that prior art exists, the purpose of this invention is to provide objectionable impurities such as a kind of not chloride, Sodium Nitrite, energy saving and environment friendly micro-emulsion cutting fluid that rust-preventing characteristic is good.

For realizing above-mentioned purpose, the technical solution that the present invention adopted is: a kind of energy saving and environment friendly micro-emulsion cutting fluid is characterized in that composed of the following components:

MO: 15%-25%;

Extreme pressure anti-wear additives: 3%-10%;

Mix hydramine: 7%-10%;

Non-ferrous metal rust-preventive agent: 0.2%-0.5%;

Boric acid: 4%-6%;

AS: 8%-12%;

Sulphonate rust-preventive agent: 5%-12%;

Alcohol type coupler: 1%-5%;

Nonionogenic tenside one: 4%-6%;

Nonionogenic tenside two: 5%-7%;

Emulsification adjustment agent: 0.5%-1.5%;

Sterilant: 0.5%-2%;

Kilfoam: 0.1%-0.3%;

Deionized water: surplus.

Said MO is common 10#, 15#, 22# MO, also industrial white oil, hydrogenated base oil, pickling purified MO; Said extreme pressure anti-wear additives can be a sulfide aliphatic acid ester 3010,3015,3025, also sulfurized fatty; Said mixing hydramine is: by trolamine: diethylolamine is 6:4, or trolamine: monoethanolamine is 3:7; Said non-ferrous metal rust-preventive agent is the phenylpropyl alcohol triazole; Said boric acid is that technical grade or commercial grade all can; Said AS is an oleic acid amine; Said sodium sulfonate rust-preventive agent is petroleum sodium sulfonate; Said coupler can be ethanol, USP Kosher, terepthaloyl moietie; Said nonionogenic tenside can be tween 80, NP-10 etc.; Said nonionic emulsifying agent is SP80, MOA3; Said emulsification mediator agent is trolamine, MOA3; Said sterilant can be RH-893, triazine; Said skimmer can be used any water insoluble defoamer; Said deionized water is common softening water, or pure water, or adds EDTA disodium 0.5, adds tap water and also can.

A kind of energy saving and environment friendly micro-emulsion cutting fluid, its beneficial effect is: the emulsification grain is little, and is stable; The oil-containing ratio reduces greatly, and rust-preventing characteristic is superior to oil-in-water type, not chloride and nitrite; Waste liquid is after the oil treatment of simple branch, but excess biodegrade in the water, environmental and save energy.

Embodiment

Concoct with two stills:

1, a still: anti-extreme pressure agent, sulfide aliphatic acid ester 4% are added in the still, close to dissolve in 20 minutes with 15# white oil 18% cool tone and open.

2, two stills: the trolamine that adds phenylpropyl alcohol triazole 0.3% and blending ratio earlier and be 4:6 heats up 80 ℃ with diethylolamine, transfers to add boric acid 5% after opening molten opening, and pours in the still after keeping 80 ℃ to dissolve, and concocts with oil, is muddy shape.

3, add sulfide fat oil soap or alizarin assistant 8% to a still, 65 ℃ of blendings of constant temperature fluid is transparence.

4, two stills add petroleum sodium sulfonate (702) 7% or petroleum sodium sulfonate (702) 5%, zinc naphthenate (704) 2%, and terepthaloyl moietie 2% is poured still blending into after accent is opened.

5, a still adds water 35% blending and is warming up to 65 ℃.

6, in a still, add 5% T80, sterilant 1%, blending.

7, in a still, add 5% or 6% SP80, the limit edged is observed, transparent till.(add 2% after adding 3% earlier, slow adduction is observed, should not be too fast, in order to avoid excessive, liquid deepens the back earlier to transparent).

8, survey emulsifying stability, add water, and survey pH value by 1:20; If less than 8.7, then add trolamine, adjust and measure with balance; Amount with 0.2% adds step by step, if greater than 9, and emulsification has oil slick to add the MOA3 adjustment to add less; After the adjustment several times, reaching emulsification does not have oil slick, and pH value is to get final product between 8.6 to 9.

9, with still cooling, be cooled to normal temperature, go out still.
