Abstract
The invention discloses a cutting liquid composition to manufacture metal, which comprises the following parts: 0.1-10% cobalt-inhibiting additive with triazine, 0.5-40% antirust agent, 0.05-5% corrosion inhibitor, 0.2-20% pH value adjustor and tap water, basic oil or composition to manufacture cobalt knife or cobalt manufacturing material in the cutting manufacturing course.
Description
Technical field
The present invention relates to a kind of cutting fluid composite that is used for metal processing.
Background technology
In metal working tool, contain cobalt hard alloy and more and more widely used.Carry out in the process of metal processing at these cutters of processing and these cutters of use, the cobalt metal in the material can dissolve in the cutting fluid, makes cutting fluid pulverize redness or scarlet.Cobalt continue to ooze out corrosive wear and the workpiece accuracy of not only having accelerated cutter and material.The more important thing is because cobalt is subjected to the strictness control of environmental regulation to the harm of human health and physical environment.Show that according to medical research cobalt not only causes human asthma, segmental bronchus fibrosis, also influential to heart, skin, Tiroidina and hemocyte.Therefore, reduce as far as possible that the content of cobalt is the target that people pursue in the Working environment.It is to reduce the effective ways that cobalt oozes out in cutter and the work material that use can suppress the special cutting fluid that cobalt oozes out.
Just carried out related work abroad from the eighties in 20th century.John M.McChesney etc. has applied for 3 pieces of essentially identical patents of content, US4315889, EP0068061 and CA1144144, and these 3 pieces of patents have been described by adding triazole or thiadiazole compound and have effectively been suppressed oozing out of cobalt.
Rolf etc. mention in US4976919 and EP0180561 by a kind of alkyl alcohol amine material and play the effect that presses down cobalt, again in patent US6432890 with list or dialkyl phosphate and the compound use of alkyl alcoholamine, think can further improve metal working fluid press down the cobalt effect.But easily water body is produced rich phosphatization influence behind the phosphorated water-soluble metalworking liquid discharging of waste liquid.
Disclosedly in the above-mentioned document press down the cobalt agent, all do not relate to and to solve the problem that suppresses microorganism growth simultaneously.
Summary of the invention
Technical problem to be solved by this invention is that cobalt-containing alloy is perishable and the problem that cobalt oozes out takes place in cutting fluid.A kind of new cutting fluid composite that is used for metal processing is provided.This cutting fluid composite is used for containing cobalt cutter processing or contains cobalt metal material processing process and has the cobalt metal of inhibition and ooze out effective, environmentally friendly, has good antimicrobial properties simultaneously, can effectively suppress the breeding of cutting fluid microorganism, simultaneously do not need to add again other antiseptic-germicides in the cutting fluid, can keep the advantage of good biologically stable yet.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows: a kind of cutting fluid composite that is used for metal processing comprises following component by weight percentage:
