Abstract
The invention relates to a high-performance high-water base lubricant which consists of sulfonated nano-diomand particles, water-soluble organic phosphate, amine and water; and the weight percentages of the components of the high-performance high-water base lubricant are as follows: 0.05 to 0.3 percent of nano-diomand particles, 0.5 percent of water-soluble organic phosphate, 2 percent of amine and the balance of water. According to different purposes, functional addition agents can be added in the lubricant and the addition can be 0.1 percent to 5 percent. The high-performance high-water base lubricant has the positive effects as follows: as the nano-diomand particles have small diameters, high activity, the nano-diomand particles can be expected to be stuffed in a friction microdomain to adsorb and stop the direct contact of secondary friction surfaces, thereby reducing the exceeding friction and improving the bearing capacity; and under the condition of friction, the water-soluble organic phosphate can react with a basal body (such as iron) to generate iron phosphate and other inorganic lubricant films so as to reduce and resist friction. Therefore, the high-performance high-water base lubricant has the advantages of high bearing performance and excellent friction resistance and can solve the problem of poor lubricity of high-water base lubricant, and can be used as working fluid during cutting and grinding metal.
Description
[technical field]
The present invention relates to the lubricant of metal manufacture field, specifically, is a kind of high-performance high-water base lubricant.
[background technology]
Metal processing is a traditional industry, and lubricant is the generally product of use of the sector institute.In recent years; because countries in the world are more and more paid attention to environment protection, are paid close attention to save energy; therefore; the focus that shortcomings such as poor because of biodegradability, the easy contaminate environment of the extensive at present mineral base lubricating agent product that adopts become words and pay close attention to; the lubricant of exploitation environmental protection becomes the developing direction of metal manufacture field lubricant research; and high-water-based liquid (High Water-based Fluid, HWBF) exploitation of lubricant is one of them main research contents.
High-water base lubricant is meant the liquid lubricant of being made up of the water of 1～5% functional additive and 95～99%.Compare with traditional oil lubricant, high-water base lubricant has the following advantages:
(1) oil-containing not, thereby cleaning have more reduced environmental pollution, have also helped workers'health;
(2) substitute oil with water, consumption of petroleum is descended, saved petroleum resources;
(3) cost is low, and its price is about 1/10th of mineral oil, one of seventy points of the synthetic liquid of phosphoric acid ester;
(4) good cooling results, temperature rise is lower, and ratio of specific heat is twice than oil, and heat transfer rate is than 2.5 times of innages;
(5) difficult combustion, safety, its main body is a water, is particularly suitable for using as occasions such as mine, Steel Plant at inflammable and explosive environment;
(6) easy cleaning has been avoided the adhesion of oil lubricant to workpiece, helps the processing of lower procedure;
(7) viscosity temperature characteristic is good, the viscosity index height, and compressibility is little.
Owing to have above plurality of advantages, make that high-water base lubricant is expected to be widely used in industrial circles such as metallurgy, mine, glass, plastics, man-made fiber as hydraulic transmission medium (especially difficult combustion medium), and as the metalworking coolant in the processing of metals such as cutting, grinding, calendering, punching press, drawing.
But, also because the main body of high water-based lubricating liquid is a water, and its water viscosity is low, film-forming properties is poor, supporting capacity is low, and pair of friction components often are in boundary lubrication condition, thereby friction, serious wear.These problems have become to limit the bottleneck that high water-based lubricating liquid is applied.For this reason, in actual applications,, must add slip additive for the extreme pressure that improves high-water base lubricant, lubricity such as wear-resistant.The general at present slip additive that adopts can be divided into two kinds: a kind of is oil soluble lubricating additives, contains the lubricant of lubricated active elements such as sulphur, phosphorus, chlorine and metallic element as sulfide isobutene, zinc dialkyl dithiophosphate (ZDDP), phosphoric acid ester, clorafin, lead naphthenate etc.; But these high water based lubrication liquid products exist consistency and poor stability, easy corrupt rotten problem, and, because some additives wherein are bigger as lead naphthenate toxicity, easily environment is impacted.Another kind is a water-soluble lubricant additive, as polyoxyethylene glycol and derivative, sulfosalicylic acid and dithio dipropyl acids water-soluble carboxyl acid derivative etc., adopt water-soluble lubricant additive to solve the stability problem of lubricating fluid, also have big gap but its oilness is compared with oil lubricant, fail to solve the problem of high-water base lubricant poor lubricity.
[summary of the invention]
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of load height, anti-attrition good, be the high-performance high-water base lubricant of main component with Nano diamond particle and water-soluble phosphate.
For achieving the above object, the technical solution used in the present invention is:
A kind of high-performance high-water base lubricant is made up of Nano diamond particle, water-soluble phosphate, amine and water through chemically modified, and the weight percent of its various compositions is:
Nano diamond particle 0.05～0.3%;
Water-soluble phosphate 0.5%;
Amine 2%;
Water 97.20～97.45%.
Described Nano diamond particle through chemically modified is meant the Nano diamond particle through sulfonation reaction.
Described Nano diamond particle, mean diameter are 10 nanometers.
Described high-performance high-water base lubricant, can be according to different purposes, for example: cutting fluid, grinding fluid, pressure medium etc., add functional aid, the weight percent of its various compositions is:
Nano diamond particle 0.05～0.3%;
Water-soluble phosphate 0.5%;
Amine 2%;
Functional aid 0.1%～5%;
Water surplus.
Described functional aid is inhibiter, tensio-active agent, tackifier, sterilant, essence of copper etc.
The positively effect of high-performance high-water base lubricant of the present invention is: because the Nano diamond particle diameter is little, active height, is expected in the filling of friction microcell, absorption, stops the direct contact on pair of friction components surface, minimizing excessively rubs, improves supporting capacity; And water-soluble phosphate plays anti-attrition, wear-resistant effect by generate inorganic lubricant films such as tertiary iron phosphate with matrix (as iron) under friction condition, therefore, the present invention has load height, advantage that anti-attrition is good, can solve the problem of high-water base lubricant poor lubricity, and can be used as the working fluid of metal cutting, grinding etc.
[embodiment]
Four embodiment of high-performance high-water base lubricant of the present invention below are provided, but the invention is not restricted to following embodiment.
