Problems solved by technology

The first type of emulsified oil for hydraulic supports belongs to a thermodynamically unstable system, and its stability is conditional. During use, a certain amount of oil and soap still precipitates, which can easily cause filter blockage, and the filter needs to be cleaned frequently. Combined with coal dust, it will form scales that are difficult to clean, which will block the filter of the electro-hydraulic control system; the second type of concentrated liquid for hydraulic supports is generally prepared with polymer substances such as polyethanol and anti-rust agents and oily agents. However, its biodegradation and adaptability to sealing materials are poor. In short, the existing support hydraulic fluid has problems such as poor safety, low operating efficiency and environmental pollution when used in underground mines.

preparation example Construction

[0039] Such as figure 1 Shown, a kind of preparation method that is used to realize clean concentrated hydraulic fluid, comprises following weight percentage formula and sequence step:

[0040] Step 1: Mix the Ingredients

[0041] 5-10% vegetable oil 1, 10-20% organic amine 2, 5-8% oil soap 3, 3-5% borate 4, 10-20% organic alcohol 5, 7.5-12% organic acid 6, 0.5-1% defoamer 7 is mixed with ingredients;

[0042] Step Two: Stir

[0043] Stir the above mixture at a constant temperature of 80°C for 0.5-1 hour to form a uniform brown liquid, and finally add 24-59% water 8 and stir evenly;

[0044] Step Three: Cool

[0045] Allow the stirred mixture to cool naturally;

[0046] Step Four: Filtration Filling

[0047] Filter the evenly stirred liquid to remove slag, and fill it to complete the product.

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

1. Technical field [0001] The invention relates to the field of chemical industry, in particular to a clean concentrated hydraulic fluid and a preparation method thereof, which are suitable for the application of hydraulic cylinders, especially for the application of coal mine hydraulic supports. 2. Background technology [0002] At present, the hydraulic fluid used in hydraulic supports in my country generally includes emulsified oil for hydraulic supports and concentrated liquid for hydraulic supports. The first type of emulsified oil for hydraulic supports belongs to a thermodynamically unstable system, and its stability is conditional. During use, a certain amount of oil and soap still precipitates, which can easily cause filter blockage, and the filter needs to be cleaned frequently. Combined with coal dust, it will form scales that are difficult to clean, which will block the filter of the electro-hydraulic control system; the second type of concentrated liquid for hyd...
