CN104651028A - Cutting fluid - Google Patents

Abstract

The invention discloses a cutting fluid and relates to the technical field of lubricant. The cutting fluid comprises the following components in percentage by weight: 1%-3% of p-tert-butylbenzoic acid, 2%-5% of diethanol amine, 2%-5% of benzoic acid, 3%-8% of glycerol, 0.5%-3% of bactericide, 3%-5% of emulsifier, and the balance of water. Compared with the prior art, the problems that the existing parts are easily rusted during cutting processing in spring in South of China can be reduced.

Description

Cutting fluid

Technical field

The present invention relates to technical field of lubricating oil, especially a kind of cutting fluid for borings processing.

Background technology

Cutting fluid is the important supplementary material of metal cutting process, the object of metal working fluid is used to be exactly reduce cutting force and the friction between cutter and workpiece, take away the heat of generation in cutting zone in time to reduce cutting temperature, reduce tool wear, improve tool life, thus enhance productivity, improve workpiece surface roughness, ensure Workpiece Machining Accuracy, reach economic optimum.Existing a kind of cutting fluid is made up of mineral oil and oil in water emulsion, especially in the spring that southern water south wind is many, after using the metal parts of this cutting fluid to machining to cool, exactly after slushing oil is coated on metal parts surface, still there is part corrosion phenomena can occur.

Summary of the invention

Problem solved by the invention is to provide a kind of cutting fluid, to reduce the existing south problem that spring, part machining got rusty easily.

In order to solve the problem, the technical solution used in the present invention is: this cutting fluid kind cutting fluid, its percentage:

To tert-butylbenzene formic acid 1% ~ 3%;

Diethanolamine 2% ~ 5%;

Phenylformic acid 2% ~ 5%;

Glycerine 3% ~ 8%;

Sterilant 0.5% ~ 3%;

Emulsifying agent 3% ~ 5%;

Water surplus.

Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: 1, be not easy to go bad, and uses directly to be coated with slushing oil to after part clean afterwards, even if the part in spring opening gas many at water south wind is also not easy corrosion; 2, owing to the addition of sterilant in cutting fluid, the bacterium grown in cutting fluid is few, cutting fluid long service life and part are not easy to get rusty.

Embodiment

Below in conjunction with example, the invention will be further described:

Embodiment 1:

To tert-butylbenzene formic acid: 1%; Diethanolamine: 2%; Phenylformic acid: 2%; Glycerine: 3%; Sterilant: 0.5%; Emulsifying agent: 3%; Water: surplus.

Embodiment 2:

To tert-butylbenzene formic acid: 2%; Diethanolamine: 4%; Phenylformic acid: 3%; Glycerine: 5%; Sterilant: 2%; Emulsifying agent: 3%; Water: surplus.

Embodiment 3:

To tert-butylbenzene formic acid: 3%; Diethanolamine: 5%; Phenylformic acid: 5%; Glycerine: 8%; Sterilant: 3%; Emulsifying agent: 5%; Water: surplus.

Above-mentioned three embodiments, all by the technical indicator required by GB/T6144-2010 standard, are considered from Financial cost, embodiment 1 best results; The detected result of embodiment 1 sees the following form:

Claims (1)
