Abstract
The present invention relates to a step quenching oil composition which is composed of mineral type base oil, a cooling accelerant, an anti-rust agent, a brightener and an anti-oxidant. The step quenching oil has good cooling performance and thermal oxidation safety, and has the characteristics of innocuity, little pollution, convenient cleaning, safe and reliable use and little deformation of quenched parts. The step quenching oil is suitable for quenching internal and external ferrules of bearings, precision parts, motorized gears, half axles, etc. made of bearing steel and carburizing steel.
Description
The present invention relates to a kind of heat-treated oil, specifically is hierarchical quenching oil.
Along with mechanotronic, national defense industry, the particularly development of aerospace flight technology, quenching technique to metallic substance requires more and more higher, many special-purpose quenching oils have been succeeded in developing on the sixties national defence, resemble vacuum quenching oil, quick bright quenc hing oil and hypervelocity hardening wet goods, the seventies, in order to solve precision component and large module gear quenching strain problem, industrially developed country develops use temperature at 120～200 ℃ isothermal quenching oil and hierarchical quenching oil, Martemp722 hierarchical quenching oil as U.S. Houghton company, the DaphneA oil that Japan bright dipping company produces, the cooling performance of above-mentioned hierarchical quenching oil and thermal oxidation stability are all not ideal enough.
The research work of China's heat-treated oil is started late, special-purpose quenching oil begins one's study in early eighties, treatment production is not because there is the high temperature grading quenching oil at present, have to substitute with high viscosity machinery oil and superheated steam cylinder oil, because these oily cooling poweies are poor, adverse consequencess such as the inhomogeneous and thermal oxidation stability of conducting heat is bad etc., causes part hardness low, and oil coke is serious.
It is strong to the purpose of this invention is to provide a kind of cooling performance, and oxidation stability is good, the hierarchical quenching oil that life cycle is long.
Hierarchical quenching oil usually under protective atmosphere as the quenchant of heated components; require quenching rear surface light; base oil fraction and refining depth are all influential to its cooling performance oxidation stability and piece surface luminance brightness, and the present invention adopts mineral oil 650SN to make base oil.
The cryogen of urging that the present composition is selected for use has two kinds, a kind of is petroleum sodium sulfonate, another kind is that molecular-weight average is 40,000 Atactic Polypropelene, in order to guarantee the luminance brightness of part, need in the component to add rust-preventive agent and brightening agent, the rust-preventive agent that the present composition is selected for use is dodecenylsuccinic acid, and brightening agent is a sorbitol monooleate.Because hierarchical quenching oil is at high temperature to use, must select excellent high-temperature oxidation inhibitor, the oxidation inhibitor that the present invention selects for use has two kinds, and a kind of is the 2.6-ditertbutylparacresol, and another kind is that molecular structure is
The composition proportioning of fractional quench oil compound of the present invention is to contain petroleum sodium sulfonate 0.3～1.5g, Atactic Polypropelene 0.3～2.0g, dodecenylsuccinic acid 0.02～0.08g, sorbitol monooleate 0.3～1.0g, 2.6-ditertbutylparacresol 0.5～0.8g, 4,4 methylene radical-2.6 DI-tert-butylphenol compounds, 0.3～1.0g in the 100g base oil.
The preparation of hierarchical quenching oil of the present invention is that Atactic Polypropelene is mixed with base oil by nitrogen protection under 100～120 ℃ of temperature; be mixed into certain density mother liquor, then this mother liquor other additive, base oil in composition stirred under 70 ± 5 ℃ of temperature.
Compare with existing hierarchical quenching oil, hierarchical quenching oil of the present invention has good cooling performance and thermal oxidation stability, and have nontoxic, pollute for a short time, it is convenient to clean, the safe in utilization and little characteristics of parts quenching after strain.This hierarchical quenching oil is applicable to the bearing inner and outer ring that bearing steel, converted steel are made, quenchings such as precision component and automobile gear, semiaxis.
Embodiment:
Hierarchical quenching oil with the described composition proportioning of table 1 is a sample
Table 1
Do not carried out the cooling performance test with present embodiment hierarchical quenching oil and Japanese DaphneA oil content, Fig. 1 is a DaphneA hierarchical quenching oil speed of cooling curve, Fig. 2 is a hierarchical quenching oil speed of cooling curve of the present invention, from Fig. 1 and Fig. 2 as can be seen, hierarchical quenching oil cooling performance of the present invention is better than Japanese DaphneA oil, the maximum cooling velocity ratio of hierarchical quenching oil of the present invention is very fast, and appear at the high-temperature zone, and the zone below 300 ℃, the speed of cooling of oil is slack-off, this is unusual ideal, to reducing the distortion of part, demonstrates favorable cooling effect.

Do the test of quenching light respectively with hierarchical quenching oil of the present invention and Japanese DaphneA oil and U.S. Houghton722 hierarchical quenching oil in little vacuum oven, test-results sees Table 2.

As can be seen from Table 2, the part luminance brightness is better after the marquenching oil quenching of the present invention.
Carry out oxidation test with present embodiment oil and DaphneA oil and Houghton722 oil, this test is in the presence of Fe, Cu catalyzer, feed dry air in 165 ℃, the viscosity ratio and the carbon residue increased value of formation testing measured in oxidation after 96 hours continuously, it the results are shown in Table 3, and hierarchical quenching oil thermal oxidation stability result of the present invention as can be seen from Table 3 is better than DaphneA oil and Houghon722 oil.
