Abstract
The invention relates to the technical field of chemical industry, in particular to cleaning concentrate hydraulic fluid and a preparation method thereof. The cleaning concentrate hydraulic fluid is a mixed solution containing 5-10% of vegetable fat, 10-20% of organic amine, 5-8% of oil soap, 3-5% of borate, 10-20% of organic alcohol, 7.5-12% of organic acid, 0.5-1% of defoamer and 24-59% of water. The preparation method includes: mixing ingredients, stirring, cooling, filtering and filling. The cleaning concentrate hydraulic fluid has the advantages of being good in hard water resistance, having enough lubricating films and penetrating quality, being high in stability, good in degradation property, less in dosage and transportation cost, environment-friendly, good in anti-corrosion performance, easy to prepare and the like and is applicable to hydraulic cylinders, especially coal mine hydraulic supports.
Description
One. technical field
The present invention relates to chemical field, particularly a kind of clean concentrated solution hydraulic fluid and preparation method thereof is suitable for hydro-cylinder and uses, and is particularly suited for coal mine hydraulic supporting and uses.
Two. background technology
At present, the hydraulic liquid of China's hydraulic support generally comprises these two kinds of hydraulic support oil in water emulsion and hydraulic support concentrated solutions.The first hydraulic support oil in water emulsion belongs to thermodynamic unstable system, its stability is with good conditionsi, in use still have certain oily graining out to go out, easily cause filter screen to block, need to often clean filter screen, and these oily soaps are combined the dirt that form to be difficult to cleans with coal dust, thereby then can stop up its filter member to electrohydraulic control system; The second hydraulic support concentrated solution generally is equipped with the modulation of rust-preventive agent, oiliness improver with polymer substances such as PVOHs again and forms, but its biological degradation and relatively poor to the adaptability of sealing material, existing bracket hydraulic liquid exists and is used for that job security is poor under the mine, operating efficiency low and the problem such as environmental pollution in a word.
Therefore seek a kind of can utilization, facile hydrolysis and environment amenable renewable resources be raw material, do not contain mineral oil and polymer substance clean concentrated solution hydraulic fluid and preparation method thereof and just seem particularly important.
Three. summary of the invention
For achieving the above object, the component of clean concentrated solution hydraulic fluid of the present invention all is to measure by weight percentage, and its component is the mixing solutions of 5-10% Vegetable oil lipoprotein, 10-20% organic amine, 5-8% oil soap, 3-5% borate, 10-20% Organic Alcohol, 7.5-12% organic acid, 0.5-1% defoamer, 24-59% water.
Be used for realizing that the preparation method of clean concentrated solution hydraulic fluid comprises following weight percent component and sequential steps:
The first step: batching is mixed
With the mixing of preparing burden of 5-10% Vegetable oil lipoprotein, 10-20% organic amine, 5-8% oil soap, 3-5% borate, 10-20% Organic Alcohol, 7.5-12% organic acid, 0.5-1% defoamer;
Second step: stir
Above-mentioned compound was stirred under the condition of 80 ℃ of constant temperature 0.5-1 hour, become even brown liquid, add at last 24-59% water, stir;
The 3rd step: cooling
Allow the mixed solution naturally cooling that stirs;
The 4th step: filter can
The cooled liquid filtering that will stir removes slag, can product.

7. described defoamer is any one or two kinds of mixture of polyethers or methyl-silicone oil.
Above component consists of hydraulic support concentrated liquor of the present invention, thin up again when work is used, and recommendation concentration is 5%, is used for hydraulic support and uses.
Can be used as component Vegetable oil lipoprotein of the present invention, organic amine, organic acid, Organic Alcohol, oily soap, borate, defoamer is that material is easily purchased in market, and especially Vegetable oil lipoprotein is the renewable resources from plant extract such as natural coconuts.
Advantage of the present invention:
When (1) product configuration became working fluid, solution was as clear as crystal, and anti-hard water is strong;
(2) enough lubricant films and penetrating quality are arranged, make the energy transformation of hydraulic support and transmit more sufficient, faster;
(3) do not contain mineral oil, formed thermodynamic stable system, stability improves greatly;
(4) pbz polymer material not improves its degradation property greatly, prolongs the work-ing life of tightness system;
(5) product is concentrated, and pH value is stable, is difficult for producing bacterial reproduction, greatly reduces usage quantity and the trucking costs of working fluid;
(6) adopting animal-plant oil is the glycerol of raw material and facile hydrolysis, and raw material has recyclability and biodegradable, and is environmentally friendly;
(7) product has extremely strong rustless property, and support is protected fully.
(8) the step of preparation process condition is brief, need not specific installation.
