Description
Technical field
The present invention relates to a kind of more high-grade environment-friendlycutting cutting fluids of performance.
Background technology
Many cutting fluids on the market at present almost only focus on " antirust, lubrication, cooling " three kinds of performances, and for such as
It is the occasion of resin grinding wheels cutting, other than more than performance, for improving cutting efficiency, for cleaning and clean cut end
Mouth, colorless and odorless do not stimulate skin and respiratory tract and national environmental protection blowdown to grab increasingly tighter etc., are not finely divided market also
Use occasion and deep market survey.
Invention content
The object of the present invention is to provide a kind of more high-grade environment-friendlycutting cutting fluids of performance.
To achieve the above object, the technical solution used in the present invention:A kind of high-grade environment-friendlycutting cutting fluid of more performances, including

45%, alcohol ether carboxylate 9-13%, borate 8.5-10.5%, surplus are water.
Preferably, including following components in percentage by weight:Amine carboxylic acid 8%, hydramine 12%, aliphatic ester 4.8%, mineral
Oil 40%, alcohol ether carboxylate 11%, borate 9.5%, surplus is water.
The beneficial effects of the present invention are:
Cutting fluid of the present invention uses the non-chlorine raw material new technology of polymer inlet, colourless, tasteless, do not stimulate skin and breathing
Road meets environmental requirement, passes through SGS environmental certifications.Cutting fluid of the present invention has more more excellent than other domestic brands following comprehensive
Close performance:
(1) cutting efficiency is improved;
(2) outstanding cooling;
(3) it is suitble to the lubricity of cutting;
(5) excellent rust-preventing characteristic;
(6) spatter property of cutting port is more preferable;
(7) cleaning when cutting is more preferable;
(8) cutting chamber and the high speed defoaming of water tank;
(9) rapid subsidence of impurity;
(10) the anti-corrosion rust inhibition of lathe;
(11) outstanding water based fire protection;
(12) high-grade environment-protecting and non-poisonous innocuousness.

Specific embodiment
Embodiment 1
Present invention applicant is absorbed in accurate cutting and high-grade quality and environmentally friendly concerted activities people, constantly throws in this respect
Enter to research and develop, cutting fluid optimized, table 1 is the optimization formula of more high-grade environment-friendlycutting cutting fluids of performance, by table 1 into
Divide and mix up to the cutting fluid, Fig. 1 is the present embodiment cutting liquid stock solution photo:
The 1 more high-grade environment-friendlycutting cutting fluid formulas of performance of the present invention of table
The performance test of the high-grade environment-friendlycutting cutting fluid of the more performances of the present embodiment:
1st, cutting efficiency is improved
Because the present invention turns down the content of Lubrication Composition, friction coefficient bigger during emery wheel cuts workpiece is conducive to improve
The sharp ability of cutoff wheel, it is sharper using the grinding wheel cutting of the present embodiment cutting fluid compared to other existing cutting fluids,
Cutting efficiency higher equally uses GC120LB cutoff wheels by comparative test, and feed speed is similarly 12mm/min, cut end
The silicon steel iron block of mouth 12*25, cutting fluid use 1:8 are watered, and are ensureing cutting port without burn, impulse- free robustness, smooth
Under quality requirements, as long as the grinding wheel using the present embodiment cutting fluid is cut 180 seconds, such as Congress of Industrial Organizations of state promise brand, U.S. Kui Ke
Brand etc. wants 220 seconds or so.
2nd, outstanding cooling
Other require it is constant under the premise of, cutting fluid of the present invention can be with 1:(25~30) are watered, other brands are only promised to undertake
1:20 are watered, because the present invention, which can compete, converts more water, cooling is stronger.
3rd, it is suitble to the lubricity of cutting
Lubricity the 1st point of raising cutting efficiency with more than is the logical relation communicated.
4th, excellent rust-preventing characteristic;
Fig. 2 is the rust prevention test picture of the present embodiment cutting fluid, and " amorphous iron is tested in the left side for the present embodiment cutting fluid in figure
" amorphous iron block " is tested in block ", the right for other brands, and similary 1:10 are watered, and room temperature environment, getting rusty after 5 days are placed on after cutting
Effect.
Fig. 3 is another rust prevention test picture of the present embodiment cutting fluid, and " silicon is tested in the left side for the present embodiment cutting fluid in figure
" silicon steel iron block " is tested in steel block ", the right for other brands, and similary 1:10 are watered, and room temperature environment are placed on after cutting, after 10 days
It gets rusty effect.
5th, the spatter property of cutting port is more preferable
Because the spatter property of cutting fluid of the present invention is more preferable, when cutting, comes off to grinding wheel and the cleaning clean-up performance of metallic fine particle
, iron silica-alumina material is equally cut, as shown in figure 4, the left side is this implementation in figure
The cutting fluid cutting effect effect of example, the right is other brands.
Cleaning when the 6th, cutting is more preferable
With above 2nd point, more water can be converted, because the not sticky cleaning of cutting fluid of the present invention is fine;
7th, the rapid subsidence of impurity;
Fig. 5 is the settling test after the present embodiment cutting fluid use, and the left side is that the present embodiment cutting fluid uses 3 days * 8 in figure
Time hour, the right is the similary usage time of other brands, while samples static placement 15 minutes, and the present embodiment cutting fluid is apparent
Limpid layering, here it is outstanding settleability, conducive to quickly purification utilization again.
8th, the anti-corrosion rust inhibition of lathe
With above to the rust-preventing characteristic of workpiece, it is made because lathe metal plate etc. is also iron plate;
9th, outstanding water based fire protection
With above 2nd point, because more water can be converted, fire line is stronger
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention rather than the present invention is protected
The limitation of range is protected, although being explained in detail with reference to preferred embodiment to the present invention, those of ordinary skill in the art should
Understand, technical scheme of the present invention can be modified or replaced equivalently, without departing from the essence of technical solution of the present invention
And range.
