Description
Technical field
The invention belongs to cooling fluid technical field, be specifically related to a kind of machining center rust coolant liquid.
Background technology
All cooling fluid will be used during machining center cutting workpiece in present enterprise, general cutting fluid will meet cooling, lubrication, cleaning, antirust four objects, the cooling fluid of present use generally be complete synthesis or semi-synthetic or oil in water emulsion, main component is alkanolamine ester class, oils, the things such as tensio-active agent, but there is summer easily smelly, difficulty dilution in winter, the defect of rust-proof effect difference, rust-preventive agent is also making with Sodium Nitrite in the enterprise of some low grades, Sodium Nitrite adds water, cooling is splendid, antirust also passable, but processed rear workpiece surface can be shone into and have hickie, and Sodium Nitrite is carcinogenic, the health of operator is caused damage.
Summary of the invention
For solving the problem, the invention discloses machining center rust coolant liquid, with low cost, it is made up of tensio-active agent and lubricant and rust-preventive agent, not containing the compound such as Sodium Nitrite, oxyhydroxide, favorable rust preventing effect, free from extraneous odour, nontoxic, non-corrosiveness, safe and reliable, free from environmental pollution, long service life.
For achieving the above object, technical scheme of the present invention is as follows:
Machining center rust coolant liquid, is characterized in that: be made up of the component of following weight percent: butanols Soxylat A 25-7 30-50%; Sodium phosphate 0.2-0.6%; Phosphatase 11-5%, trolamine 3-8%; Polyoxyethylene glycol 6-10%; Borax 0.5-0.9%; Heavy complex acid potassium 1-5%; Sodium orthomolybdate 0.05-0.1%; Water glass 0.1-0.2%; Deionized water 25-50%.
As a modification of the present invention, described polyoxyethylene glycol molecular-weight average is 2000-4000.
Prepare a preparation method for above-mentioned machining center rust coolant liquid, it is characterized in that: comprise the following steps:
(1) each material is taken according to weight percent;
(2) add deionized water in a kettle., then add borax, be warming up to 80-90 DEG C, stir 20-30 minute;
(3) 50-55 DEG C is cooled to; Add sodium phosphate, phosphoric acid, Sodium orthomolybdate, water glass, be stirred to material and dissolve completely;
(4) step (3) reacted mixed solution is carried out centrifugation;
(5) temperature is established to 40-50 DEG C, adds butanols Soxylat A 25-7, trolamine, polyoxyethylene glycol, stirs 40-60 minute;
(6) add heavy complex acid potassium stirring reaction 40-60 minute, finally remove mechanical impurity with screen filtration, obtain rust coolant liquid.
Filtration described in above-mentioned steps (6) is that the rust coolant liquid foreign matter content after filtration is less than 0.01% with 200 order stainless steel filter screen sieves.
Adopt butanols Soxylat A 25-7, this raw material has good viscosity-temperature characteristic and water-soluble, join in cooling fluid and can improve lubricant effect, antistatic, emulsifying power improves, cloud point and surface tension decline, reduce foam, need to add some rust-inhibiting additives when preparing cutting fluid, to prevent workpiece, lathe corrosion, and the polarity of rust-preventive agent is all stronger, Preferential adsorption on the metal surface, make the oilness of rust-preventive agent more weak, therefore butanols Soxylat A 25-7 ratio is in the feed strengthened, under 30-50% ratio, lubrication can reach balance with antirust, improve cooling fluid quality.
The metal envelope surface of the work in-process heart one deck protection passivation film can be formed after heavy complex acid potassium incorporates water; effectively can suppress corrosion of metal, heavy complex acid potassium has higher boiling point, can reduce the evaporation of moisture; can coolant inhibitor agent be used as, play sterilization, passivation.
Trolamine is used to substitute Sodium Nitrite, antirust, the incrustation scale in water can be eliminated, the pH value of cooling fluid can also be regulated.
The present invention uses sodium phosphate and phosphorylated ligand adjust ph altogether, better than Sodium Nitrite adjust ph, and anti-cancer, can reduce cooling fluid to the corrosion of metal such as iron, copper, and sodium phosphate compares cheaply with phosphoric acid simultaneously, is conducive to reducing costs.
Adopt Sodium orthomolybdate with decreasing pollution; 0.05% Sodium orthomolybdate and organic corrosion inhibitor borax compound use, rust-proof effect improves more than 60% than original cooling fluid.
The normal pH value of rust coolant liquid of the present invention is 12-13, routine use concentration is 1:15, a cooling fluid, 15 parts of water, different according to working conditions, working concentration can between 1:10 to 1:20, corresponding cutting fluid pH value is at 8.3-9.2, and now bacterium is difficult to existence, if cooling fluid pH value is low should add new cutting fluid in time, improve pH value, ensure processing work quality.
The invention has the beneficial effects as follows:
Machining center rust coolant liquid of the present invention, by compositional refinements and adopt the preparation method of science, solve the problem of cooling fluid rust-proof effect difference in the past, cooling fluid effectively removes the molecule produced in the course of processing, ensure that product is totally qualified, product has good oilness, cooling, rust-preventing characteristic and or anti-foaming performance, be applicable to cast iron, steel, the machining of the various metals such as aluminium alloy and copper alloy, cooling fluid cleans, environmental protection, not smelly, nontoxic, tasteless, skin is had no adverse effects, be specially adapted to the mechanical processing of CNC processing center machine tool and the cutting of digital controlled lathe.
