Description
Technical field
The present invention relates to a kind of cutting liquid, be specifically related to a kind of diamond linear cutting fluid, its preparation method and using method.
Background technology
In crystal silicon solar energy battery production process, diamond wire saw owing to having efficiently, low cost, the advantage such as environmental protection
Rise abruptly in silicon chip cutting industry；Diamond wire saw is to utilize plating or resin bonded method to be attached to by diamond abrasive
Steel wire surface, directly acts on silicon rod by diamond wire or silicon ingot surface produces grinding, thus reaches the effect of cutting, therefore should
The mortar spray that process mixes with cutting liquid relative to traditional mortar cutting technique-utilize cutting blade material carborundum falls at cutting of steel
On the gauze of silk composition, the silicon carbide press in mortar is made to embed the silicon rod i.e. silicon ingot table being pressed on gauze by high-speed motion
Face, forms Three-body Abrasive Wear thus produces dissection, have faster cutting speed and efficiency, but cutting simultaneously can produce
Bigger heat and abrasion, therefore cutting liquid must have preferably lubrication and cooling performance；Simultaneously because cutting process produces
Raw substantial amounts of silica flour enters in cutting liquid, and cutting liquid viscosity constantly increases, and can produce a large amount of gas during cutting liquid circulating cooling
Bubble, the silica flour that therefore cutting liquid also needs to producing has the strongest dispersibility and froth breaking suds ability；In addition in order to ensure
The silicon chip of cutting can well be applicable to lower road making herbs into wool operation, and cutting liquid must also have good cleansing power, in case cutting
Liquid residual causes the defects such as making herbs into wool white macula white point.
At present, the diamond linear cutting fluid used both at home and abroad mostly is oils and fats or common polyether super fatting agent is equipped with a certain amount of
Organic silicon defoamer forms, although this kind of cutting liquid can play certain lubrication defoaming effect, but due to organosilicon and oils and fats all
Easily adsorb silicon chip surface and cause difficult and follow-up making herbs into wool white macula problem of cleaning, simultaneously because organosilicon is not easily decomposed follow-up
Cutting waste liquor process also result in difficulty；Therefore silicon chip cutting process often brings new problem.
Therefore, a kind of easy cleaning of research, and reduce the cutting liquid that waste liquid produces, have great importance.
Summary of the invention
The technical problem to be solved in the present invention, is to provide a kind of diamond linear cutting fluid, its preparation method and using method,
Using trans block polyether, amino-polyether and polyvalent alcohol is raw material, enhances the defoaming capacity of cutting liquid, dispersibility and clear
Wash ability, it is to avoid silica flour is reunited or deposition causes line clogging and cutting liquid remain the later process making herbs into wool white macula caused
The defects such as white point, simultaneously because cutting liquid is mainly made up of polyethers, just possesses excellent lubrication under low concentration, cool down and disappear
Bubble performance, greatly reduces the COD discharge in cutting waste liquor, simultaneously because make cutting waste liquor easily locate without organic silicon defoamer
Reason.
For solving above-mentioned technical problem, the technical solution used in the present invention is:

The third as the present invention limits, and the molecular weight of described polyvalent alcohol is 3000～5000.
As the further restriction of above-mentioned restriction, described polyvalent alcohol is Polyethylene Glycol, polypropylene glycol or polytetramethylene glycol
In one.
As the 4th kind of restriction of the present invention, described organic acid is the one in caprylic acid, different n-nonanoic acid or capric acid.
Present invention also offers the method preparing above-mentioned diamond linear cutting fluid, it is carried out according to following steps order:
1) raw material is got the raw materials ready；
2) at ambient temperature, trans block polyether, amino-polyether, polyvalent alcohol are added to water according to percentage by weight
In, stir, add organic acid afterwards and proceed stirring, finally regulating to pH is 7.0～7.1, finally prepares diamond
Wire cutting liquid.
Present invention also offers the ratio of the method using above-mentioned diamond linear cutting fluid, this diamond linear cutting fluid and water
For 1:400～500.
Owing to have employed above-mentioned technical scheme, compared with prior art, acquired technological progress is the present invention:
The present invention uses trans block polyether, amino-polyether and polyvalent alcohol to be raw material, enhances the froth breaking energy of cutting liquid
Power, dispersibility and cleansing power, it is to avoid silica flour is reunited or deposition causes line clogging and cutting liquid residual cause
The defects such as later process making herbs into wool white macula white point.Simultaneously because cutting liquid is mainly made up of polyethers and does not contains organic silicon defoamer, greatly
