Description
Technical field
The present invention relates to a kind of anti-flame hydraulic fluid composition and method of making the same, be applicable to be used for making steel, the hydraulic efficiency system of various device such as ironmaking, continuous casting, hot rolling and die cast metal.
Background technology
During hydraulic work system, because there is the difference of each position flow velocity in hydraulic efficiency oil in flow process, cause liquid internal to have certain internal friction, also have friction simultaneously between liquid and the pipeline inner wall, these all may cause hydraulic fluid temperature to raise.Hydraulic fluid temperature raises and will cause internal and outernal leakage to increase, and reduces its mechanical efficiency.Owing to higher temperature, hydraulic efficiency oil can expand simultaneously, causes compressibility to increase, and control action can't well be transmitted.And heating is the inherent feature of hydraulic efficiency system, can't eradicate and can only alleviate as far as possible, such as the good hydraulic efficiency oil of functional quality.
And, in actual production, the hydraulic efficiency system of many equipment is to be operated near flame, high temperature or the molten metal, because the unexpected incidents such as break of the gas of environment for use and liquid leakage or pipeline, joint happen occasionally, in case hydraulic liquid leaks and causes fire, not only threaten operating personnel's personnel safety, also be unfavorable for the device security of enterprise and stablizing of production.So good hydraulic efficiency oil antagonism combustion performance also has higher requirements.
The fire resistant hydraulic oil of present industrial use mainly is: water base hydraulic oil (emulsion, water-ethylene glycol), phosphate type and synthetic ester type are applicable to different pressures scope and differing temps scope respectively.But because of being subjected to the restriction of factors such as use temperature, working pressure, material adaptability, security and environmental protection, these hydraulic efficiency oil can not satisfy the requirement of modernization industry fully, be mainly reflected in: under the High Temperature High Pressure situation, emulsion stability is poor, be easy to generate decomposition, and waste oil liquid is also relatively more serious to the pollution of environment.Water-ethylene glycol Applicable temperature scope is at-30 ~ 60 ℃, and pressure is less than the hydraulic efficiency system of 20MPa, but relatively poor because of its lubricity, greatly limited its use; Phosphoric acid ester fire resistant hydraulic oil non-flame properties can be more outstanding, but toxic to the people because of it, contaminate environment, and price is much higher than other hydraulic efficiency oil, has greatly limited its use.In recent years, synthetic ester fire resistant hydraulic oil has obtained very fast development, but these synthetic ester fire resistant hydraulic oils usually, in order to reach higher oilness and good anti-oxidant energy, the add-on of additive is often very high, will cause the ash content of oil product big like this, degradation rate is low, residue multipotency shortcoming.
Summary of the invention
The purpose of this invention is to provide a kind of anti-flame hydraulic fluid composition, it is wide that this hydraulic composition has excellent non-flame properties, winter hardiness, resistance to abrasion, Applicable temperature scope, anti-oxidant extremely strong with anti-corrosion capability, good stability, has extremely long work-ing life, human body is had no side effect, all pollution-free to atmosphere, environment and water source etc.
For achieving the above object, the invention provides a kind of anti-flame hydraulic fluid composition, said composition comprises following raw materials in percentage by weight:
Distilled water 30-40%;
Ethylene glycol 30-40%;

Described thickening material is selected from the polyethers any one or several mixture arbitrarily, and described polyethers comprises materials such as polyoxyethylene poly-oxygen propylene aether, polyglycol ether.Described thickening material plays the effect of viscosity index improver.When lesser temps, the solubleness of macromolecular organic compound molecule in oil in these viscosity index improvers is little, and molecule curls closely little group, thereby the oil viscosity increase is very little; And when high temperature, its solubleness in oil increases, and the linear molecule of curling shape expands and extends, thereby it is bigger that viscosity is increased, and makes that the viscosity with temperature variation of anti-flame hydraulic fluid composition of the present invention is less, Applicable temperature scope wide (50 ~ 750 ℃).
The alkalescence that described pH stablizer is non-single component is mixed conditioning agent; It comprises alkalescence such as lipid acid ammonium and benzotriazole and mixes conditioning agent, and the pH value is 9.0 ~ 10.0.Described lipid acid ammonium also plays the effect of rust-preventive agent, and preferably, this lipid acid ammonium is selected ammonium oleate; Described benzotriazole also plays the effect of sanitas.Therefore, described pH stablizer not only is used to regulate the pH value of composition, can also improve the rust-preventing characteristic and the preservative property of anti-flame hydraulic fluid composition.
Described ethylene glycol can strengthen the non-flame properties of hydraulic composition, promotes low-temperature stability, can also strengthen resistance to abrasion.
Described anti-flame hydraulic fluid composition also comprises the pigment additive of percentage ratio meter 0.1 ~ 1% by weight, its objective is the eye-catching effect of playing, its position in hydraulic efficiency system of convenient observation.
The present invention also provides a kind of above-mentioned anti-flame hydraulic fluid preparation of compositions method, and it comprises following concrete steps:
Step 1 under the room temperature, mixes distilled water and ethylene glycol;
Step 2 in above-mentioned mixed solution, adds the pH stablizer for preparing in advance, control pH value scope 9.2-9.5;
Step 3 adds thickening material in the mixed solution of step 2 gained, stir, and can obtain described anti-flame hydraulic fluid composition.
The preparation method of described pH stablizer: with lipid acid ammonium and the benzotriazole mixed of ratio 8 ~ 12:1 by weight, add an amount of distilled water again, be as the criterion dissolving fully, mix, control pH value scope is 9.0 ~ 10.0.
Anti-flame hydraulic fluid composition provided by the invention has suitable viscosity, superior viscosity-temperature characteristics, and good chemical stability can layering under the situation of normal operation and maintenance, undergoes no deterioration long service life.High viscosity index that anti-flame hydraulic fluid of the present invention has and good lubricity make its performance that is similar to mineral hydraulic efficiency oil, can bear higher operating pressure.Anti-flame hydraulic fluid provided by the invention does not add extreme pressure agent, through four ball valve lubricants wear-resistant-extreme pressure property test, have the one-level abrasion resistance.
Because the easy polymerization small molecules of the defoamer that adds meeting makes degree of cleaning reduce, the present invention does not add defoamer, still has antifoam performance preferably, and has clean-up performance preferably,
In a word, anti-flame hydraulic fluid composition of the present invention has excellent non-flame properties, winter hardiness, resistance to abrasion, preservative property, rust-preventing characteristic, have extremely long work-ing life, and the Applicable temperature scope is wide.Anti-flame hydraulic fluid composition additive of the present invention is few, does not contain any objectionable impurities, and is nontoxic, safe in utilization.Therefore the component of composition of the present invention is easy to biological degradation, and waste treatment is easy, is widely used in making steel, in the hydraulic efficiency system of various devices such as ironmaking, continuous casting, hot rolling and die cast metal.
