Abstract
The present invention provides a water-based cutting fluid, which comprises, by weight, 65-70% ethylene glycol, 2-4% of triethanolamine oleate, 3-5% of a nonionic surfactant, 1-5% of an extreme pressure anti-wear agent, and 20-30% of water. According to the present invention, the extreme pressure anti-wear agent is added to the cutting fluid, such that the surface tension of the cutting fluid is substantially reduced, the fluidity and the permeability of the cutting fluid are substantially improved, the wettability of the cutting fluid on the abrasive material is substantially improved, the dispersion of the abrasive material is increased, the damage on the silicon wafer due to the agglomeration of the abrasive material is avoided, and the silicon wafer cutting yield can be easily improved; the protection film can be formed on the surface of the silicon wafer, such that the silicon wafer is easily washed; and the lubricating effect, the wear resistance and the cooling property of the cutting fluid are improved.
Description
Technical field
The invention belongs to photovoltaic field, particularly water base silicon chip cutting fluid.
Background technology
In photovoltaic solar silicon chip cutting process, water base silicon chip cutting fluid has to use for as in silicon chip cutting process
A kind of auxiliary material consumable product, its consumption extends with the growth of the silicon chip processing industry of photovoltaic solar industry and China.
Water base silicon chip cutting fluid presses composition classification main inclusion oiliness cutting liquid and aqueous cutting liquid two big class.The first kind is cut
Cut the oiliness cutting liquid mainly with mineral oil as main component for the liquid product, wherein contain mineral oil, anticorrosive, anti-extrusion machine
Deng material；Cutting liquid itself is inflammable, and environmental pollution is larger, needs fluorine-containing alkane solvent during cleaning silicon chip simultaneously.Equations of The Second Kind
Aqueous cutting liquid product can be dissolved in water or be water dispersible, and cleaning silicon chip water, without organic solvent, to human body and environment
Harmless.Therefore Equations of The Second Kind cutting liquid is to use more species at present.
At present in the production process in cutting it may appear that cutting liquid fail to soak well silicon chip and discrete cut under
The silica flour coming is so that silica flour is gathered in the situation that silicon chip surface produces abrasion to silicon chip.
Content of the invention
Goal of the invention: for solving Shortcomings in prior art, the present invention provides a kind of water base cutting liquid, existing for solving
There is the technical problem that in technology, silicon chip is worn and torn by silica flour.
Technical scheme:
A kind of water base cutting liquid, each component including forming according to following percentage by weight: ethylene glycol 65%～70%,
Triethanolamine oleate 2%～4%, nonionic surfactant 3%～5%, extreme pressure anti-wear additives 1%～5%, water 20%～
30%.
Further, in the present invention, described triethanolamine oleate is the mixture of oleic acid and triethanolamine.
Further, in the present invention, described extreme pressure anti-wear additives are dialkyl dithiocarbamate, dialkyl disulfides
For one of phosphate, lead naphthenate, coconut oil triglycolyl amine.Here organic-molybdenum salt, antimonic salt, lead salt not only can have
Effect ground improves the extreme pressure anti-wear of lubricating grease, can also improve oxidation stability and the rust-preventing characteristic of lubricating grease simultaneously.
Beneficial effect:
Increased extreme pressure anti-wear additives in the cutting liquid of the present invention so that the surface tension of cutting liquid reduces, substantially increase
The mobility of cutting liquid and permeability, greatly improve the wetability to abrasive material for the cutting liquid, improve the dispersiveness of abrasive material, it is to avoid
Abrasive agglomerate is formed block and is brought damage to silicon chip, is conducive to improving the yield rate of silicon chip cutting；And guarantor can be formed in silicon chip surface
Cuticula, makes silicon chip be easier to be cleaned by, and improves lubricant effect, wearability and the cooling of cutting liquid.
Specific embodiment
Embodiment 1
A kind of water base cutting liquid, each component including forming according to following percentage by weight: ethylene glycol 70%, oleic acid three
Monoethanolamine 3%, nonionic surfactant 3%, dialkyldithiocarbamacompositions sodium 2%, deionized water 22%.Described non-from
Sub- surfactant is with rosin, cis-butenedioic anhydride and polyamine etc. as Material synthesis.
Embodiment 2
A kind of water base cutting liquid, each component including forming according to following percentage by weight: ethylene glycol 67%, oleic acid three
Monoethanolamine 3%, nonionic surfactant 2%, dialkyldithiocarbamacompositions sodium 1%, deionized water 27%.
According to the ratio in embodiment, each component is mixed, at a temperature of 120 DEG C, with the speed stirring of 120r/min
2min～5min, you can obtain water base silicon chip cutting fluid.Extreme pressure anti-wear additives in the present embodiment are chosen as dialkyl dithio ammonia
Base sodium formate, forms chemical reaction film in metal surface, plays lubrication, prevents scratches on metal surface so that silicon chip can hold
It is extreme boundary lubrication by boundary lubrication the harshest, prevent silicon chip surface to be worn.
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
