CN104560343A - Preparation method of coolant for mechanical cutting - Google Patents

Abstract

The invention relates to a coolant, particularly a preparation method of a coolant for mechanical cutting. The method comprises the following steps: boiling tap water, airing to normal temperature, pouring into a reaction vessel, heating to 80 DEG C, adding sodium chloride, sodium bicarbonate, sodium benzoate and butyl hydroquinone, stirring until the materials are completely dissolved, cooling to 65 DEG C, stirring, respectively adding an antirust complex and an antiwear lubricant, cooling 35 DEG C, adding an antiknock, stirring for 30-60 minutes, filtering out impurities through a screen, and cooling to normal temperature, thereby obtaining the coolant. The preparation technique is simple and easy to operate; the prepared coolant has favorable environment friendliness, favorable antiskid property and favorable antirust property; the coolant is free of nitrites, heavy metals or other harmful substances; the coolant is simple in formula and convenient to operate; and the synthesized product can be stored for more than two years.

Description

A kind of preparation method of cut mechanically cooling fluid

Technical field

the present invention relates to a kind of cooling fluid, be specifically related to a kind of preparation method of cut mechanically cooling fluid.

Background technology

In machinery production, often can run into the work needing cutting, as sawing machine uses band saw cutting, lathe turning cutting etc., cutting process because cutter and absorption surface close, lastingly, very high heat can be produced in cutting process, the frictional force produced between cutting tool and workpiece also can cause certain wearing and tearing to cutter, so cutting process very loss cutter, general cutting fluid will meet cooling, lubrication, cleaning, antirust four objects, rust-preventive agent is also making with Sodium Nitrite in existing most of enterprise, Sodium Nitrite adds water, cooling is splendid, antirust also passable, but processed rear workpiece surface can be shone into and have hickie, and Sodium Nitrite is carcinogenic, the health of operator is caused damage.

Summary of the invention

For solving the problem, the invention discloses the preparation method of machining center rust coolant liquid, its preparation method is simple, with low cost, and the cooling fluid lubrication prepared, cooling performance are good.

The preparation method of a kind of rust coolant liquid of the present invention, it comprises the steps:

(1) tap water is boiled rear airing to normal temperature, pour in reaction vessel, be heated to 80 DEG C, add sodium-chlor, sodium bicarbonate, Sodium Benzoate, butylhydroquinone, be stirred to material and dissolve completely, be then cooled to 65 DEG C;

(2) add antirust complex compound, antifriction lubricant respectively after stirring, be then down to 35 DEG C, then add octane promoter, stir 30 to 60 minutes;

(3) strainer filtering falls impurity, is cooled to normal temperature;

(4) get this product 10% ~ 15% directly to dissolve with the tap water 85% ~ 90% of boiling and can use.

The simple easy handling of cooling fluid preparation technology that the present invention prepares, the cooling fluid good environmental protection prepared, antiskid, good antirust property, cooling fluid of the present invention is not containing the objectionable impurities such as nitrite and heavy metal, and working fluid can be recycled 6 months without rotten, smelly, to lathe with workpiece is corrosion-free, non-foaming, free from extraneous odour, be convenient to cutting prod, the non-corroding in 15 days that works, antirust ability are strong.The present invention fills a prescription simply, simple operation, and synthetics can preserve more than 2 years.

Embodiment

A preparation method for cut mechanically cooling fluid, it comprises the steps:

(1) tap water is boiled rear airing to normal temperature, pour in reaction vessel, be heated to 80 DEG C, add sodium-chlor, sodium bicarbonate, Sodium Benzoate, butylhydroquinone, be stirred to material and dissolve completely, be then cooled to 65 DEG C;

(2) add antirust complex compound, antifriction lubricant respectively after stirring, be then down to 35 DEG C, then add octane promoter, stir 30 to 60 minutes;

(3) strainer filtering falls impurity, is cooled to normal temperature, both obtains cooling fluid;

(4) to get parts by weight be 10% ~ 15% cooling fluid with boiling rear parts by weight is that 85% ~ 90% tap water directly dissolves and can use.
