Description

A kind of neodymium iron boron later stage cut is with the preparation method of cutting fluid

Technical field

The present invention relates to magneticsubstance Machining Technology for Cutting field, relate in particular to the preparation method of a kind of neodymium iron boron later stage cut with cutting fluid.

Background technology

Along with the raising of cutting technology, the kind of cutting fluid is more and more.Can be divided into oil base cutting fluid and water-base cutting fluid two big classes substantially by its type.

It is raw material that the oil base cutting fluid adopts MO, wax, mixing oil and extreme pressure oil more, and general oilness is good, but cooling performance is relatively poor.Be used in the courses of processing such as high speed and heavy cut, worsen bad border health because of smoldering tempestuously, even the danger that causes fire is arranged.Because the splashing and be scattered and also aggravated pollution of oil,, often need add organism extreme pressure agent, oiliness improver, rust-preventive agent and the oxidation inhibitor etc. of chloride, sulphur, phosphorus simultaneously for preventing deterioration by oxidation, improve its lubricated extreme pressure property to environment.These additives are the influential organic cpds of HUMAN HEALTH, by developed country and territorial restrictions uses such as the U.S., Europe.

But water-base cutting fluid has the good cooling results save energy and characteristics such as increase work efficiency, and day by day is widely used in the metal working process, and the trend that progressively substitutes oil lubricant is arranged.Wherein the superiority with complete synthesis type water-base cutting fluid is more outstanding especially.Compare with microemulsion (claiming semi-synthetic liquid again) with traditional MO emulsion (emulsification oil type) that contains; High water base Totally synthesized cutting fluid is not owing to contain machinery oil fully; All have outstanding feature at aspects such as cleaning, rust-preventing characteristic, cooling property, processing visuality, bacterinertness and stability, thereby obtain gradually to use widely.

Mainly comprise technologies such as section, abrasive disc, punching in the sintered NdFeB post-treatment, must use cutting fluid in its post-treatment with good lubricated, antirust and cooling performance.Neodymium iron boron product is because product itself contains REE, and chemical property is active, powder metallurgical body has and is prone between space, different metal form galvanic cell reaction etc., and product is prone to oxidation, perishable, and general water-base cutting fluid is difficult to satisfy fully the requirement of its processing.See from existing patent, document and technology; Existing cutting fluid mainly can be applicable to processing such as metals such as iron, aluminium, copper are cut, mill, and is few to the water-base cutting fluid product report of sintered NdFeB post-treatment, even a small amount of report is arranged; Also there is such-and-such defective, can not satisfies the use needs.Therefore, it is just imperative with special-purpose water-based milling liquid to develop a kind of sintered NdFeB.

Summary of the invention

The objective of the invention is to propose the preparation method of a kind of neodymium iron boron later stage cut with cutting fluid, the cutting fluid that adopts this method to prepare is different from the cutting fluid of prior art, can be suitable for the later stage cut of NdFeB material.

For reaching this purpose, the present invention adopts following technical scheme:

A kind of neodymium iron boron later stage cut is with the preparation method of cutting fluid, and said cutting fluid is made up of following component by weight percentage: quadrol 5-7%, Yi Bingchunan 14-16%, oleic acid 8-10%; Sebacic acid 1-3%, water-soluble phosphate 3-5%, polyethers 4-6%, methyl benzotriazazole 12-14%; TX-100.5-0.7%, Z 150PH 6-8%, 5-chloro-2-methyl-4-isothiazoline-3-ketone 0.1-0.3%; Silicone emulsion 0.5-0.7%, Virahol 3-5%, water surplus; Said preparation method comprises the steps:

1) quadrol, Yi Bingchunan, oleic acid, sebacic acid are mixed stirring 20-30 minute at 60-70 ℃, cool off subsequent use then;

2) polyethers, methyl benzotriazazole, TX-10, Z 150PH, 5-chloro-2-methyl-4-isothiazoline-3-ketone and Virahol are dissolved in the 30-40 ℃ of water successively; And stirred 30-40 minute;

3) mixture that step 1) is obtained joins step 2) in the mixture that obtains, add silicone emulsion then, and stir and got final product in 60-90 minute.

The cutting fluid of the present invention preparation and gets final product after the dilution proportion of water according to 1:15 in use.

The present invention has following beneficial effect with respect to prior art:

What 1) the present invention had confirmed cutting fluid on the bases of a large amount of experiments respectively forms component; Has excellent antirust and oxidation-protective effect for NdFeB material; With low cost; It is harmful and cause the composition of environmental pollution that the raw material that is adopted does not contain MO, nitrite, muriate etc., is specially adapted to use in the post-treatment such as grinding, punching of sintered neodymium iron boron material, and neodymium iron boron speciality material is had good cutting, cooling, lubricated, rust inhibition.

2) cutting fluid of the inventive method preparation is utilized lubricant, extreme pressure agent and rust-preventive agent reasonably combined of environment-friendly type, has guaranteed oilness, extreme pressure property and the rust-preventing characteristic of cutting fluid; Utilize the reasonably combined of organic bases and organic acid and special auxiliary agent, weakened the corrosion dissolution phenomenon of the viscose glue that cutting fluid uses the bonded neodymium-iron-boron material greatly; Utilize dispersion agent and tensio-active agent to reduce the surface tension of solution, thereby strengthened the perviousness and the settling property of cutting fluid; This liquid is minimum to viscose glue solvability in the process-cycle of bonded neodymium-iron-boron material, the situation of the big or tool damage of processing precision of products error can not occur causing because of the cutting fluid mixing of viscose.
