Technical field

The present invention relates to hydraulic oil technical fields, and in particular to a kind of high-low temperature resistant hydraulic oil and its production technology.

Background technique

The oily abbreviation hydraulic oil of hydraulic system, hydraulic oil is a kind of lubricating oil, is situated between as the work in Hydraulic Power Transmission System Matter, hydraulic oil have lubrication, cooling and anti-rust action.With the continuous development of hydraulic technique, to the quality requirement of hydraulic oil It is higher and higher, and the raising of hydraulic oil quality, and promote the further perfect of hydraulic technique.Due to using hydraulicdriven machine For tool equipment mostly in field work, operating ambient temperature, which changes, it requires that greatly hydraulic oil must have suitable viscosity and good Good viscosity-temperature characteristics energy, could provide enough film strengths and lubricity for hydraulic device, it is ensured that the smooth working of system, especially It is in extremely hot, severe cold area is the smooth starting for ensuring hydraulic pump, it is desirable that hydraulic oil must have brilliant high/low temperature mobility, To guarantee the normal lubrication of hydraulic system, equipment is protected not to be worn.

Summary of the invention

The object of the present invention is to provide a kind of high-low temperature resistant hydraulic oil and its production technologies.

A kind of high-low temperature resistant hydraulic oil, the raw material including following weight parts: 60-90 parts of base oil, 0.2-2 parts of antioxidant, 0.3-1 parts of antirust agent, 0.1-0.5 parts of detergent-dispersant additive, 0.05-0.1 parts of matal deactivator, 0.1-0.7 parts of demulsifier, antiwear additive 1.5-4 part.

Further, the high-low temperature resistant hydraulic oil, the raw material including following weight parts: 65 parts of base oil, antioxidant 1 Part, 0.8 part of antirust agent, 0.3 part of detergent-dispersant additive, 0.08 part of matal deactivator, 0.5 part of demulsifier, 2 parts of antiwear additive.

Further, the base oil is the phenyl silicone oil and tricarboxymethyl propane oleate that weight ratio is 1.5-2:1 Mixture.

Phenyl silicone oil is the product after part methyl is substituted by phenyl in methyl-silicone oil, than the dimethicone of same viscosity With higher viscosity-temperature coefficient, lower freezing point, flash-point, anti-compression properties under stress viscosity variation faster, and phenyl The lower temperature resistance of silicone oil is significant, also has good mobility at subzero 70 DEG C.

Tricarboxymethyl propane oleate has that excellent greasy property, Viscosity Index are high, flame resistance is good, hydrolytic stability Good, high-flash, low volatilization, low-temperature characteristics are good.

Further, the antioxidant is the mixture of antioxidant T534 and antioxidant T501 that weight ratio is 1:1.

Antioxidant T534 is a kind of high-temperature antioxidant, and thermal stability is relatively good, and antioxygenic property under the high temperature conditions is prominent Out, the features such as oil-soluble is good and the compatibility of other additives is good.

Antioxidant T501 is to use paracresol and isobutene for oil dope made from raw material, rise in the oil it is anti-oxidant and Anti- glue effect, oil-soluble are relatively good.

Further, the demulsifier is the mixture of demulsifier T1001 and demulsifier DL-32 that weight ratio is 1:1-3.

Demulsifier T1001 appearance is brown to flaxen liquid, has very high degradation property and water extractibility, to fresh Or degradation lubricating oil it is effective.

Demulsifier DL-32 is a kind of oil soluble polyether class high-molecular compound of more monomer synthesis, goes emulsifying effectiveness very bright Aobvious, addition can not only extend the service life of the oil product on a small quantity, and can enhance effect of other auxiliary agents in oil product.

Further, the antiwear additive is the mixture of antiwear additive T323 and antiwear additive T306 that weight ratio is 1:1-3.

Antiwear additive T323 is a kind of Ashless type multipurpose additive, has good abrasion resistance and extreme pressure property, with other Additive has good compatibility, can be improved the anti-oxidant abrasion resistance of oil product, and it be also in lubricating grease it is a kind of very Effective extreme pressure agent.

Antiwear additive T306 has excellent fire-retardant, wear-resisting and fungus resistance energy, and volatility is low, good electric property.

Further, the antirust agent is antirust agent T705A；The detergent-dispersant additive is detergent-dispersant additive T106；It is described Matal deactivator is matal deactivator T706.

Antirust agent is a kind of synthesis bleeding agent of super grade high efficiency, it can strongly penetrate into iron rust, erosion, in greasy dirt to light Loose ground is disposed, and is had infiltration derusting, is loosened lubrication, resists the performances such as burn into protection metal.

The main function of detergent-dispersant additive is that engine interior is made to keep cleaning, makes the insoluble substance generated in colloidal suspension Floating state, is unlikely to be further formed carbon deposit, paint film or greasy filth.

Matal deactivator is used to inhibit the catalytic action of metal, especially copper to oil oxidation, to give full play to antioxygen The effect of antigum inhibitor reduces antioxidizing and antigum agent dosage.

The production technology of the high-low temperature resistant hydraulic oil, comprising the following steps:

(1) matal deactivator is added in the base oil of Xiang Jiare and antioxidant, constant temperature is mixed evenly, obtain mixed liquor；

(2) surplus stock is added in mixed liquor, and stirred evenly, filter to obtain the high-low temperature resistant hydraulic oil.

Further, in step (1), the heating temperature of the base oil is 80-100 DEG C, and 25- is mixed in constant temperature 35min is uniformly mixed.

Further, in step (2), mixed liquor is cooled to 60-70 DEG C, surplus stock is added in mixed liquor, constant temperature Stirring 60-90min is uniformly mixed.

The invention has the benefit that a kind of each raw material of high-low temperature resistant hydraulic oil of the present invention is organically incorporated in one It rises, makes the high-low temperature resistant hydraulic oil that there is preferable high and low temperature resistance, and flash-point is higher.A kind of resistance to height of the present invention Warm hydraulic oil uses in wider temperature range has preferable viscosity, burning point relatively high, bigger using safety coefficient, makes It is long with the service life.
