Description
Technical Field
The invention relates to the technical field of hydraulic oil, in particular to water-resistant flame-retardant hydraulic oil and a preparation method thereof.
Background
The flame-retardant hydraulic oil is hydraulic fluid which is difficult to ignite flame and has small flame spreading tendency, and is mainly applied to high-temperature, near-fire or fire-dangerous working environments in the industries of metallurgy, coal, electric power and the like, and is used as a hydraulic transmission medium of a hydraulic system. Widely used are water glycol type flame-retardant hydraulic fluid and unsaturated polyol oleate type flame-retardant hydraulic oil. Compared with the water glycol type, the unsaturated polyol oleate type flame-retardant hydraulic oil has outstanding flame-retardant property, excellent lubricity, protection and environmental protection and is degradable. However, it has disadvantages in that it is sensitive to water and moisture, the ester type is easily hydrolyzed and oxidized, and the service life is reduced.
In particular, the oil is used in coastal areas, south rainy seasons and other humid environments, and under the influence of trace moisture, unsaturated polyol oleate type flame-retardant hydraulic oil is easier to hydrolyze and oxidize, so that the acid value is rapidly increased, and the oil corrodes equipment. The valve body is seriously stuck, blocked and the system is unstable. Meanwhile, long-term water, dust and other pollutants promote the breeding and reproduction of microorganisms, so that the performance of oil products is deteriorated, and metal material microorganisms are corroded to form sedimentary substances such as oil sludge, paint films and the like. The normal operation of the equipment is affected, even risks such as shutdown are caused, and unnecessary economic losses are brought.

The preparation method of the water-resistant flame-retardant hydraulic oil comprises the following steps:
1) Adding solid high-temperature antioxidant and hydrolysis inhibitor into 1/2 unsaturated polyol oleate, mixing for 0.5-1 hour by using a high-speed dispersing machine fully device at the temperature of 85-95 ℃, and then introducing the mixture into a reaction kettle after precisely filtering the mixture by using a 3 mu m filter screen until the cleanliness is less than 7 levels;
2) Adding the rest unsaturated polyol oleate into a reaction kettle, and reducing the temperature of the mixture in the reaction kettle to 55-65 ℃;
3) Adding oil-soluble polyether into a reaction kettle, and sequentially adding an anti-hydrolysis multi-effect additive, a mildew inhibitor and an anti-foaming agent;
4) Blending for 1.5-2 hours, and precisely filtering again by a 3 mu m filter screen to obtain a finished product.
The rotating speed of the high-speed dispersing machine in the step 1) is 10000-12000 r/min.
Compared with the prior art, the invention has the beneficial effects that:
according to the invention, the oil-soluble polyether is introduced into the ester base oil system, so that the hydrolysis tendency of the flame-retardant hydraulic oil is improved. The ester oil is unsaturated polyol oleate, and the oil-soluble polyether of the alkylene oxide with the carbon number more than or equal to 4 and the derivative thereof is completely compatible with the unsaturated polyol oleate. On one hand, the addition of the oil-soluble polyether reduces the ratio of ester oil; on the other hand, the ether bond in the oil-soluble polyether skeleton bonds with water molecules through hydrogen bond, so that the activity of the water molecules is reduced, the participation in the hydrolysis reaction is inhibited, the hydrolysis speed is slowed down, and the hydrolysis stability of the ester oil is improved.
The oil-soluble polyether has excellent sludge and deposit control ability. The oil-soluble polyether has good detergency, and is firstly degraded into low-molecular-weight oligomers and short-chain molecules after being heated and oxidized, and the low-molecular-weight oligomers and the short-chain molecules can be dissolved in polar base oil. Meanwhile, the oil-soluble polyether can also dissolve polar oil sludge products after oil oxidation, and no sediment is generated. The water-resistant flame-retardant hydraulic oil is applied to the flame-retardant hydraulic oil, so that the detergency of the oil product is obviously improved, no sediment is generated even if the oil product is oxidized at high temperature, and equipment faults such as valve body adhesion and the like are effectively avoided; the oil-soluble polyether has excellent air release performance (less than 1 min), the air release performance of the flame-retardant hydraulic oil is obviously improved within 3min after the oil-soluble polyether is added, the air in the oil is quickly released, the air bubbles in the oil are few, and the cavitation problem is not easy to generate. Reducing air pollution results in hydraulic oil failure.
The hydrolysis-resistant multi-effect additive is an ashless composite additive and has the functions of wear resistance, rust resistance and oxidation resistance. The hydrolysis-resistant multi-effect additive comprises a low acid value (acid value < 20 mgKOH/g) rust-inhibiting component. The high acid value acid rust inhibitor is easy to acidolysis the oil product and promote the hydrolysis process. The anti-hydrolysis multi-effect additive disclosed by the application is low in acid value, low in dosage and good in anti-rust effect of the anti-rust component. The method has small influence on the hydrolytic property of the base oil and good hydrolytic stability. The hydrolysis-resistant multi-effect additive comprises an ashless phosphorus-containing organic compound as an antiwear component, does not contain metal ions for accelerating hydrolysis, has small influence on hydrolysis, and is more suitable for the lubricating requirement of precision hydraulic oil elements.
The oil-soluble polyether molecules of the alkylene oxide and the derivatives thereof with the carbon number more than or equal to 4 have polarity, and can fully dissolve the hydrolysis-resistant multi-effect additive. And a lubricating protective layer for weakening chemical adsorption O-Fe bonds is formed on the surface of the metal, so that the friction coefficient is reduced. P-O bonding is formed, and the P-O bonding is used as a carrier to carry antiwear and antirust components to the metal surface, so that a stable antiwear and antirust protective film is formed. The hydrophobicity of the oil-soluble polyether is beneficial to reducing contact between water molecules and the metal surface after film formation, inhibiting water from participating in rust, playing a role in cooperative rust prevention and improving rust prevention. When the antiwear and antirust agents play a role, competitive adsorption can be formed on the metal surface, and the proportion of the components of the anti-hydrolysis multi-effect additive reaches the balance of the antiwear performance and the antirust performance. Not only can ensure good abrasion resistance, but also can obtain good rust-proof effect.
Mechanism of hydrolysis inhibitor carbodiimide to play a role in hydrolysis inhibition: unsaturated polyol oleate is easy to hydrolyze to generate carboxylic acid, the carboxylic acid accelerates the hydrolysis of ester oil, and carbodiimide reacts with carboxylic acid to generate stable ureide, so that the hydrolysis stability of the unsaturated polyol oleate is improved, the acid value is slowed down, and the service life of oil products is prolonged.
N-phenyl-a naphthylamine in the high-temperature antioxidant enables free oxidation free radicals to stop chain lock reaction so as to inhibit the high-temperature oxidation process. The 1, 2-dihydro-2, 4-trimethylquinoline polymer can improve the decomposition temperature of polyether, prevent aging degradation, and is used in combination with an anti-hydrolysis multi-effect additive to obviously improve oxidation stability, thermal stability and oxidation life, and reduce the problems of valve adhesion, equipment corrosion, sludge blockage and other hydraulic system damage caused by viscosity and acid value increase caused by high-temperature excessive oxidation.
The mildew preventive inhibits the mass exchange of microbial cells in the presence of an aqueous environment, thereby causing microbial cell death and reaction chain disruption. Effectively prevent the breeding of microorganisms in water environment and the mildew of oil products, and prolong the service life.
The anti-foaming agent is a non-silicon type anti-foaming agent, has minimal influence on air release property of oil products, and has excellent anti-foaming property.
The water-resistant flame-retardant hydraulic oil has small hydrolysis tendency and hydrolysis stability below 0.5 mgKOH/g. The oxidation stability is excellent, the rotating oxygen bomb is more than 300min, and the oxidation life can reach 800h. The acid value of the oil product is below 0.3 mgKOH. The mildew resistance is excellent, and the microbial growth and propagation can be effectively controlled when the microbial growth and propagation agent is used in an environment with water pollution for a long time, so that the mildew resistance of oil products is prevented from being deteriorated, and the microbial corrosion of metal materials is prevented. Prolonging the service life of the oil product and prolonging the oil change period to 36 months. Is especially suitable for the high-temperature flame-retardant lubrication requirements in coastal wet areas and in rainy seasons in the south.
