Description
Technical field
The present invention relates to cutting fluid technical fields, more specifically, it relates to a kind of water based synthetic cutting fluid and its preparation
Method.
Background technique
Cutting liquid is a kind of to cut in metal, cut, grinding in process for cooling down and lubricating the industrial of cutter and workpiece
Liquid is provided simultaneously with good cooling performance, greasy property, rustless property, oil removing cleaning function, anti-corrosion function and easily dilutable
The features such as, belong to a kind of novel coolant liquid.Cutting fluid is usually divided into water-insoluble (oil base) liquid and water-soluble (water base) liquid
Two major classes.The greasy property of oil base cutting fluid is preferable, and cooling effect is poor.Water-base cutting fluid lubricity compared with oil base cutting fluid
Can be relatively poor, cooling effect is preferable.But since oil base cutting fluid is at high cost and it is relatively serious to pollute, thus have
The water-base cutting fluid product of environmental type performance is the developing direction of cutting fluid, the abundance of water, and non-toxic and tasteless, is reason
The green basal liquid thought.
Currently, the water-soluble metalworking liquid used both at home and abroad is broadly divided into emulsified cutting fluid and water based synthetic cutting fluid.Before
Person is mainly made of water, mineral oil and emulsifier, its main feature is that greasy property is good, but in cooling, permeability, stability compared with
Difference, service life is short, and there are environmental issues when discharge, not biodegradable, is also easy to produce phenomena such as mouldy, smelly；The latter is main
It is made of various water-soluble additives (such as lubrication, wear-resistant, resistance to compression, antirust, surfactant) and water, its main feature is that being free of
Oil has good cooling, cleaning, stability in performance, has actively from environmental protection, saving oil resource etc.
Meaning, lubricity are poor compared with oil base cutting fluid.
In the prior art, a kind of water base application No. is being disclosed in the Chinese invention patent file of CN200910068210.3
Response type multifunctional metal machining liquid and preparation method thereof, constituent and its weight fraction are respectively as follows: surfactant
4.5-11 parts, 9-18 parts of solvent, 7-11 parts of vegetable oil acid, 12-18 parts of triethanolamine, 6-15 parts of the sodium salt of corrosion inhibitive function, inhibition
7-13 parts of agent, 3-6 parts of dimeric dibasic acid, 00.02-0.05 parts of defoaming agent, 0.2-1.2 parts of preservative, 30-40 parts of deionized water.
Existing such water based synthetic cutting fluid is in plant circulation use process, to prevent from breeding micro- life in cutting fluid
Object leads to the corrupt, smelly of water-base cutting fluid, therefore can largely add preservative into cutting fluid, and the anti-corrosion in cutting fluid
Agent, the addition of surfactant then hinder degradation of the microorganism to cutting fluid again, increase the processing difficulty of water-base cutting fluid,
So that water based synthetic cutting fluid is not degradable, therefore it is preferable and readily biodegradable water base to synthesize a kind of lubricity, anti-corrosive properties
Cutting fluid is problem to be solved.

Performance detection test
Water based synthetic cutting fluid is prepared according to the method in embodiment 1-3 and comparative example 1-6, and " is closed according to GB/T6144-2010
At cutting fluid " test that carries out the performances such as anti-corrosive properties, pH value, lubricity, storage stability and rust-preventing characteristic, according to CEC-L-33-
A-93 " Shanghai Europe superscript lubricating oil biodegrade detection " detects the biological degradation rate of water based synthetic cutting fluid, according to ASTM
The anti-microbial property of D3946-92 " the test anti-corrosion of the water dilution intermetallic composite coating fluidity of evaluation bacterium " detection water based synthetic cutting fluid,
Every testing result is as shown in table 2.
The performance test results of water based synthetic cutting fluid made from each embodiment of table 2 and each comparative example
The water based synthetic cutting fluid prepared it can be seen from data in table 2 according to method in embodiment 1-3 has good storage
Stability, rust-preventing characteristic, anti-corrosive properties and lubricity are deposited, biological degradation rate reaches 82.6% or more, have excellent biodegradability,
No pollution to the environment, and anti-microbial property is good, long service life.
Comparative example 1 differs not because being not added with essence, the rust-preventing characteristic and lubricity of water based synthetic cutting fluid with embodiment 1-3
Greatly, but biological degradation rate is substantially reduced, and antiseptic property is also decreased obviously, and bacterial population increases, and illustrates that the addition of essence can be prevented
Only there is smelly corruption in water based synthetic cutting fluid, and improves the biological degradation rate and anti-microbial property of water based synthetic cutting fluid.
Comparative example 2 is because being not added with bamboo fibre and calcium-base bentonite, anti-corrosive properties, rust-preventing characteristic and the lubrication of water based synthetic cutting fluid
Property decline is obvious compared with embodiment 1-3, biological degradation rate and anti-microbial property reduce, and illustrate bamboo fibre and calcium-base bentonite
The anti-corrosive properties, lubricity and rust-preventing characteristic that can be improved water based synthetic cutting fluid are added, improve the biology drop of water based synthetic cutting fluid
Solution rate and anti-microbial property, make the long service life of water based synthetic cutting fluid, and no pollution to the environment is more environmentally friendly.
Comparative example 3 because being not added with polyacrylamide and 2- acrylamide-2-methylpro panesulfonic acid, water based synthetic cutting fluid
Anti-corrosive properties, rust-preventing characteristic and lubricity and storage stability are declined, because of other components in polyacrylamide and cutting fluid
Friction chemical reaction occurs and generates deposition film, by the effect between film layer, improves the frictional behaviour of cutting fluid, and 2- propylene
Amide groups -2- methyl propane sulfonic acid can effectively facilitate preservative molecules and be adsorbed on metal surface, form fine and close protective film, play
Anti-rust action, so the addition of polyacrylamide and 2- acrylamide-2-methylpro panesulfonic acid can be improved water base synthesis cutting
Anti-corrosive properties, rust-preventing characteristic and the lubricity of liquid.
Comparative example 4 is because being not added with phosphoruscontaining borate, castor oil and thiophosphoric acid trimethyl, the items of water based synthetic cutting fluid
Performance is deteriorated compared with embodiment 1-3, and containing more bacterium, biological degradation rate becomes smaller, illustrate phosphoruscontaining borate, castor oil and
Thiophosphoric acid trimethyl mutually cooperates with, and can be improved anti-corrosive properties, rust-preventing characteristic and the lubricity of cutting fluid, makes the easy drop of cutting fluid
Solution, is not easy smelly corruption, longer using the time.
Comparative example 5 is because being not added with hydroxyethyl cellulose, under the anti-corrosive properties of water based synthetic cutting fluid, rust-preventing characteristic and lubricity
