As a modification of the present invention, described defoamer is silicone emulsion.

As a modification of the present invention, described tinting material is the one in methyl red, Methylene blue.

The preparation method of a kind of cast iron process cutting fluid, it is characterised in that: comprise the following steps:

(1) following component is prepared by mass fraction: ethylene glycol Stearinsaeure fat 15-20 part, trolamine 5-8 part, ginger juice 3-5 part, ethylene glycol 8-12 part, octadecyl dihydroxy ethyl trimethyl-glycine 6-10 part, polysorbate 3-5 part, alkylphenol polyoxyethylene 6-10 part, anti-wear agent 3-5 part, rust-preventive agent 5-8 part, silicone antifoam agent 1-2 part, tinting material 0.2-0.5 part;

(2) by trolamine, ginger juice mixing, at air pressure 340-420KPa, temperature 45-55 DEG C of stirring 40-50min, stirring velocity 40-50 rev/min;

(3) octadecyl dihydroxy ethyl trimethyl-glycine, polysorbate are stirred 20-30min at temperature 70-80 DEG C, stirring velocity 30-40 rev/min, at 50 ± 5 DEG C of temperature, it is incubated 2-3h;

(4) mixture after step (2) (3) and ethylene glycol Stearinsaeure fat, ethylene glycol, alkylphenol polyoxyethylene, anti-wear agent, rust-preventive agent, tinting material are poured in autoclave pressure, it is heated to 60-80 DEG C, stirs 30-40 minute at air pressure 880-960KPa, 60-70 rev/min;

(5) add defoamer, stir 10-15min, stirring velocity 70-80 rev/min, filter after pouring out, seal barrelling.

As a modification of the present invention, the filtration described in step (5) is the sieved filter of stainless steel filter screen of 40-50 μm with mesh.

The invention has the beneficial effects as follows:

A kind of cast iron process cutting fluid of the present invention, select materials superior, with octadecyl dihydroxy ethyl trimethyl-glycine, polysorbate synthesizes new anion-nonionic type tensio-active agent, coordinate trolamine, ginger juice mixes the new hydramine lipoprotein mixture synthesized at high temperature under high pressure, the working method of employing science, High Temperature High Pressure is composited, syncretizing effect is good, not stratified, antibacterial ability is strong, favorable rust preventing effect, solve conventional cutting fluid can be corroded by lathe, rotten smelly problem, it is possible to prevent ironcasting, the corrosion of lathe internal surface, cavitation erosion and fouling, and form protective layer, cutting fluid cooling and lubricating is effective, in use throw out is few, ensure that product is totally qualified, with octadecyl dihydroxy ethyl trimethyl-glycine, polysorbate synthesizes new anion-nonionic type tensio-active agent, cutting fluid easily forms physics adsorption film between cutter and ironcasting, thus play lubrication, anti-wear agent is coordinated to have good collaborative wear-resistant effect, also lubricity can be made to significantly improve, formula for a product eliminates nitrite and phosphorus, sulphur compound, add ginger juice, environmental protection, decrease chemical substance to the destruction of environment and human body and infringement, skin is had no adverse effects, resistance to corrosion is strong, its application is more extensively economical and practical compared with prior art, nontoxic, lathe can be protected while keeping good performance, workpiece, fixture and minimizing are to the injury of operator, the smooth finish of finished surface can be significantly improved, and part can be provided good corrosion protection, it is applicable to ferrous metal, the machining of aluminum and its alloy.

The present invention adds the raw material that well deoils when alkylphenol polyoxyethylene is Mechanical processing of casting, the possible leakage of oil of lathe can be eliminated to the pollution of cutting fluid, extending working time, alkylphenol polyoxyethylene can also play the glutinous effect of glue, it is possible to the fusion of each component is played a driving role.

When ethylene glycol of the present invention guarantees processing cast iron part as solvent, product is played the effect cleaning lubrication, with trolamine, ginger juice under certain temperature, pressure used in combination, enhance resistance of oxidation, the surface mobility that moisture in the cutting fluid obtained and air is condensate in ironcasting jointly is good, do not remain, the time that lathe internal surface is corroded can be reduced, extend working time.

The present invention adds ginger juice, tea has very strong alkalescence, the general chemistry general character of tool organic carboxyl acid and the chemical property of unsaturated double-bond, at air pressure 340-420KPa, stirring the mixture formed with other raw materials at temperature 45-55 DEG C merges evenly, synchronous evaporation, keep certain concentration, and lubricating fluid keeps original alkalescence, with alkylphenol polyoxyethylene compound use, sterilization effect is good, the machine oil that lathe spills can be decomposed, eliminate harmful microorganism, delay cutting fluid deteriorating time, entirety is not smelly, and without the need to adding the alkaloid compounds such as oxyhydroxide, environmental protection, lubricant effect can also be increased, and ginger juice can reduce chemical composition to the murder by poisoning of environment and human body, suppress sharp aroma, promote Working environment.

Rust-preventive agent of the present invention is benzotriazole and the mixing of 40% zinc naphthenate High Temperature High Pressure of weight ratio 60%, not only to ironcasting favorable rust preventing effect, and the antirust corrosion mitigating effect of steel, nickel, weldment is also very good, suitability is wide, corrosion mitigating effect is good, SODIUMNITRATE, Sodium Nitrite is replaced with trolamine, environmental protection, antirust, the incrustation scale in water can be eliminated, the PH value regulating lubricating fluid can also be assisted, prevent cutting fluid moldy metamorphism when storing, ensure that the storage time of cutting fluid reaches more than 18 months.

Defoamer of the present invention is silicone emulsion, and defoaming effect is good, accelerates heat trnasfer, reduces air to the oxidation of alcohol class, and much slower adds man-hour bubble to the pitting of object.

Tinting material of the present invention is methyl red or Methylene blue, makes cutting fluid be rendered as difference look, in use finds that color change is serious, then shows that lubricating fluid goes bad ineffective, it is necessary to changes.

Cutting fluid routine use concentration of the present invention is 1:16-20, and one part of cutting fluid adds 16-20 part water, different according to working conditions, working concentration can change, and corresponding lubricating fluid pH value is at 8.3-9.1, and now bacterium is difficult to existence, duration of service is long, ensures processing work quality.
