Abstract
The invention discloses a high-property high-water based lubricant composition, which comprises the following parts: 95-99% water and 1-5% functional additive (lubricant and alkali) and lucricating additive with nanometer silica particle and soluble phosphate, wherein the even grain size of nanometer silica particle is 10-60nm; the high-water based lubricant consists of nanometer silica particle and soluble phosphate, which improves bearing capacity (PB value) and reduces spot-abrasion diameter (D3040); the water based lubricant is fit for metal manufacturing liquid to cut and polish.
Description
Technical field
The present invention relates to a kind of lubricant of metal manufacture field, particularly relate to a kind of high-water base lubricant.
Background technology
Since the nineties; along with in the world wide to the pay attention to day by day of environment protection, save energy; the mineral base lubricating agent product that extensively adopts is owing to exist biodegradability poor at present; the shortcoming of contaminate environment; be faced with the severe challenge of environmental requirement, development environment close friend's lubricant becomes the developing direction of lubricant.(High Water-based Fluid, HWBF) lubricant occurs under such background high-water-based liquid just.
High-water base lubricant is meant the liquid of being made up of the water of the functional additive of 1-5% and 95-99%.Compare with traditional oil lubricant, high-water base lubricant has the following advantages:
(1) reduces environmental pollution, favourable workers ' health.Because high-water base lubricant is oil-containing not, thereby more clean;
(2) save petroleum-based energy.For the promoting the use of of oil, petroleum-based energy consumption is descended with water;
(3) cost is low, and its price is about 1/10 of mineral oil, 1/70 of the synthetic liquid of phosphoric acid ester;
(4) good cooling results, temperature rise is lower, and its specific heat ratio oil is twice, and heat transfer rate is than 2.5 times of innages;
(5) difficult combustion, safety.Its main body is a water, thus be particularly suitable for inflammable and explosive environment, as mine, Steel Plant etc.;
(6) easy cleaning has been avoided the adhesion of oil to workpiece, is beneficial to next procedure;
(7) viscosity temperature characteristic is good, the viscosity index height, and compressibility is little.
Above plurality of advantages makes high-water base lubricant be expected to be widely used as hydraulic transmission medium in the industrial machineries such as metallurgy, mine, glass, plastics, fiber (especially difficult combustion medium) and as the metalworking coolant in the metal-processing industries such as cutting, grinding, calendering, punching press, drawing.But high water-based lubricating liquid is because main body is a water, and water viscosity is low, film-forming properties is poor, supporting capacity is low, and friction pair often is in boundary lubrication condition, thereby friction, serious wear, is the bottleneck that the high water-based lubricating liquid of limitation is applied.
For this reason, for the extreme pressure that improves water base lubricant, lubricity such as wear-resistant, must add slip additive in actual the use.The at present general slip additive that adopts can be divided into two kinds, a kind of commercial lubricant that contains lubricated active elements such as sulphur, phosphorus, chlorine and metallic element for oil soluble lubricating additives such as sulfide isobutene, zinc dialkyl dithiophosphate (ZDDP), phosphoric acid ester, clorafin, lead naphthenate etc.But the high water based lubrication liquid product that obtains exists consistency and poor stability, easily corrupt rotten, and because toxicity such as existing oil soluble lubricating additives such as lead naphthenate are bigger, also environment has been caused pollution.Another kind is a water-soluble lubricant additive, as polyoxyethylene glycol and derivative, sulfosalicylic acid and dithio dipropyl acids water-soluble carboxyl acid derivative or the like, adopt soluble oil to solve the stability problem of lubricating fluid, also have big gap but its oilness is compared with oil lubricant, fail thoroughly to solve the difficult problem of high-water base lubricant poor lubricity.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, adopted and singly to have disperseed the nano silicon oxide particle and the compound slip additive of a kind of water-soluble phosphate slip additive that exist in a kind of water as high-water base lubricant.
A kind of high-performance high water-based lubricant composition that the present invention proposes is made up of nano silicon oxide particle, water-soluble phosphate, alkali and water.The weight proportion of each composition is:
The nano silicon oxide particle is 0.05-1%;
Water-soluble phosphate is 0.05-1%;
Alkali is 2%;
Water is 95-99%.
Used nano silicon oxide in the above-mentioned prescription, size of particles is the 10-160 nanometer.
Used water-soluble phosphate is the alkyl polyoxyethylene ether phosphoric acid ester in the above-mentioned prescription, and wherein alkyl contains 4-10 carbon, and the polymerization degree of Soxylat A 25-7 is 4-20.
Used alkali is sodium hydroxide, ammoniacal liquor or thanomin in the above-mentioned prescription.
According to the use occasion of high-water base lubricant, also can contain other functional aids in the prescription, as the inhibiter of copper, tensio-active agent, tackifier, sterilant, essence or the like.
Beneficial effect of the present invention: nanoparticle is expected to stop the direct contact of surface of friction pair in microcell filling, the absorption of rubbing minimizing excessive friction, raising supporting capacity because particle diameter is little, active height; Water-soluble lubricant additive plays antifriction, wear-resistant effect by generate inorganic lubricant films such as tertiary iron phosphate with matrix (as iron) under friction condition.By load height and the good advantage of conventional film lubricant antifriction quality, give full play to its synergy like this, to solve the problem of high-water base lubricant poor lubricity in conjunction with the solids lubricant.This high water-based lubricating liquid is suitable as metal working fluids such as cutting, grinding.
Embodiment
