Abstract

The invention discloses a special cutting fluid for an aluminum alloy wheel hub, which belongs to the field of the chemical industry. A formula for the cutting fluid comprises, by mass, 15 to 20% of petroleum sodium sulfonate, 10 to 12% of triethanolamine oleate, 2% of dodecenylsuccinic acid, 0.5 to 1% of benzotriazole, 3 to 5% of a nonionic surfactant H, 5 to 10% of an antirust agent, 10 to 15% of alkamine, 15 to 20% of an emulsifier, no more than 2% of an antiseptic and no more than 1% of an antifoaming agent, with the balance being machine oil No. 10, wherein triethanolamine oleate and the nonionic surfactant H in the formula are synthesized by the inventor. The prepared cutting fluid has the following advantages: the cutting fluid is easy to dilute and is durable; the cutting fluid has a good anti-rust property and good cooling performance, so a cutter is more durable; a weak solution of the cutting fluid is semitransparent, and during utilization of the weak solution of the cutting fluid, the table board of a machine tool is not oily, and processing visibility is high; the cutting fluid is clean and environment-friendly, has no stink, no toxicity and no odor, so a cleaner working environment can be provided to operating personnel, no corrosion and swelling effects are exerted on the paint and sealing members of the machine tool, and no harm is posed to a human body.

Description

The special-purpose cutting fluid of a kind of aluminium alloy wheel hub

Technical field

The invention belongs to chemical field, particularly the special-purpose cutting fluid of a kind of aluminium alloy wheel hub.

Background technology

Aluminium alloy wheel hub is in the course of processing, need processing cutting, boring, use cutting fluid can reduce rake face and smear metal, friction between rear knife face and machined surface, the forming section lubricant film, thus cutting force, friction and power loss reduced, reduce surface temperature and the cutter abrasion at cutter and workpiece blank friction position, prolong cutting-tool's used life, improve the machinability of workpiece material.Simultaneously in working angles, can effectively clean smear metal and various impurity, and have antirust function.

Summary of the invention

The object of the invention is to: provide a kind of aluminium alloy wheel hub special-purpose cutting fluid, its constituent mass per-cent is as follows: petroleum sodium sulfonate 15-20%, triethanolamine oleate ester 10-12%, dodecenylsuccinic acid 2%, benzotriazole 0.5-1%, nonionogenic tenside H3-5%, rust-preventive agent 5-10%, amido alcohol 10-15%, emulsifying agent 15-20%, sanitas＜2%, defoamer＜1%, No. 10 machinery oil surplus.

This cutting fluid, triethanolamine oleate ester and nonionogenic tenside H are synthetic by oneself in its main component, and other components are buied from market, and its preparation method is as follows:

(1) preparation of nonionogenic tenside H: rosin and cis-butenedioic anhydride carry out copolyreaction under the effect of catalyzer, and temperature of reaction is controlled at 150-180 ℃, multipolymer further with polyamine generation neutralization reaction, generate nonionogenic tenside H.Product is the reddish-brown thick liquid;

(2) triethanolamine oleate ester synthesis: oleic acid mixes by 1: 3 mol ratio with trolamine, temperature is controlled at 120-150 ℃, the COOH group of oleic acid and trolamine-OH group generation esterification, generate a kind of water soluble oils triethylenetetraminehexaacetic acid alkanolamine ester oiliness improver;

(3) prescription carries out each component mixing and adds defoamer, emulsifying agent, rust-preventive agent etc. stirring generation cutting fluid finished product by mass percentage.

The emulsion that during use this cutting fluid is made into 2-3% (is used the stoste of 2-3%, the deionized water and stirring that adds 97-98% becomes emulsion, as use tap water, then water hardness should be less than 400ppm, otherwise need to add anti-hard water agent), this emulsion is translucent, and rust-preventing characteristic, cleaning and oilness are good, and the advantage of following several respects is arranged:

1, easily dilutable, durable uses under normality, and the quality guaranteed period is more than 1 year;

2, good antirust property, and have rust removing function;

3, cooling performance is good, and cutter is more durable;

4, the diluent state that is translucent, in the use procedure, the lathe table top is without greasy feeling, and processing visibility meter is high;

5, this product cleaning, environmental protection, not smelly give operator with cleaner Working environment, to lathe paint and sealing element without corroding and swelling action;

6, this product is nonpoisonous and tasteless, and is without bad stimulation, harmless to operator's skin.
