Description
Technical field
The present invention relates to the production fields of quenching oil, and in particular, to a kind of environment-friendly type vacuum quenching oil and its preparation side
Method.
Background technology
Metal parts, in order to ensure the processing performance and mechanical performance needed for its acquisition, leads to after a variety of process
Often it is heat-treated.The heat treatment of steel workpiece is after being heated to certain temperature, is kept for a period of time, then with pre-
A kind of comprehensive process process that fixed speed cools down, austenitizing, quenching and three key steps of tempering including steel,
The key for wherein determining part performance is quenching technical process.
Compared with normative heat treatment technology, since vacuum heat treatment technology has non-oxidation, without decarburization, degreasing, degassing, zero
The advantages that reproducibility of part surface-brightening, the small, technique of deformation and mechanical property is good, energy saving, service life is long, obtains fast in recent years
Speed development, at present on the more demanding engineering goods part of the product qualities such as aerospace industry, precision component, tool and mould
To being widely applied.
Vacuum oil quenching is the main technique of vacuum heat, and the quality for quenching cooling directly determines the group after workpiece quenching
It knits and performance.Since vacuum quenching oil has, saturated vapor is low, critical pressure is low, workpiece surface brightness is high, chemical after quenching
The characteristics such as stability is good, service life is long, impurity and carbon residue are few, acid value is low.Therefore, in vacuum oil quenching, hardening media is generally adopted
With dedicated vacuum quenching oil without using conventional quenching oil.
There are ZZ-1, ZZ-2 and each enterprise's Own Brand vacuum quenching oil currently on the market, but performance and quality difference are larger,
It is primarily present following defect：
1. vacuum quenching oil currently on the market just reaches since flash-point is relatively low using standard, in actual use process
In, since vacuum drying oven vacuum degree is high, oil temperature is higher, causes the too early ebullition, gasification of oil product and escapes, not only causes dirt to air
Dye simultaneously because oil product effusion needs to add fresh oil, also results in production cost influence；
2. most of vacuum quenching oils currently on the market are using high molecular polymer (polyolefin), imidazoline oleate
Additives are waited, for these additives on the one hand due to being artificial synthesized high molecular polymer, hardly possible carries out biodegradation, and environment is caused
Pollution, it is easily carcinogenic on the other hand due to being aromatic hydrocarbon substance；
3. vacuum quenching oil is very high to moisture requirement, in actual use, do not allow containing moisture, and some producers
Vacuum quenching oil department's benzene -80 grade that can but add suitable content there is the additive of stronger emulsifying capacity, these additives are easy
Make oil emulsion and bring moisture into, make oil deterioration, the using effect of vacuum quenching oil can be substantially reduced in actual use.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of preparation method of environment-friendly type vacuum quenching oil.Ring of the present invention
The preparation method of guarantor's type vacuum quenching oil overcomes the deficiency of background technology, and the vacuum quenching oil properties of product being prepared are dashed forward
Go out；There can be higher cooling capacity in wider pressure limit.
The technical problems to be solved by the invention, which also reside in, provides a kind of environment-friendly type vacuum quenching oil.
Technical solution is as follows used by the present invention solves above-mentioned technical problem：A kind of preparation of environment-friendly type vacuum quenching oil
Method, the raw material of the environment-friendly type vacuum quenching oil include according to parts by weight：72~88.7 parts of base oil, poly isobutene fourth two

Further, the preparation method of the environment-friendly type vacuum quenching oil, includes the following steps：
(1) base oil is pumped into vacuum reconciliation kettle, opens stirring, open vacuum system, oil temperature is heated to 60~80 DEG C,
System vacuum is kept in -0.096MPa, 15~30min of stirring；
(2) close vacuum system, using vacuum reconcile kettle vacuum by more 1~5 part of polyisobutene succinimides, oil
1~5 part of sodium sulfonate, 8~15 parts of chlorinated paraffin, 0.5~1 part of molybdenum dialkyldithiocarbamacompositions of vulcanization, 4,4 '-di-2-ethylhexylphosphine oxide
0.1~0.5 part of (2,6- di-tert-butylphenols), 0.1~0.3 part of 2,6~di-tert-butyl p-cresol, polydimethyl siloxane fluid 0.1~0.2
Part, 0.5~1 part of dodecenylsuccinic acid are pumped into vacuum reconciliation kettle successively；
(3) vacuum system is opened, keeps system oil temperature at 60~80 DEG C, keeps system vacuum in -0.096MPa, stirring
30min；
(4) by after mixture obtained by step (3) after testing qualification, filtering is filling true up to finished product environment-friendly type of the invention
Air quenching kerosene.
Preferably, the base oil is three classes base oil.
