Problems solved by technology

The quality of the emulsified oil or concentrate used for hydraulic supports directly affects the accuracy of the hydraulic support. If the high-water hydraulic fluid has an abnormal phenomenon that is hard to recover after condensation in winter (oil separation, soap separation, floc, sediment, jelly-like substance), causing the blockage of the pipeline system and the phenomenon of "thrombosis", which affects the safety, efficiency and high production of coal mines

Abstract

The invention discloses a concentrated liquid for a rapid reduction type hydraulic support in a low temperature environment and a preparation method thereof. The present invention is made of the following components by mass: the total mass is 100 parts, including 5-15 parts of polymerized amino acids; 4-10 parts of nonionic and anion-based composite coupling agents; 2-6 parts of alcohol amine type buffers ; 13-30 parts of organic and inorganic composite pour point depressant; 6.1-13.7 parts of non-ferrous metal and ferrous metal composite corrosion inhibitor; 1-3 parts of mold and bacteria inhibitor; 1-3 parts of alcohol-modified polyether; the balance is water . Its preparation method: adding polymeric amino acid, non-ionic and anionic-based composite coupling agent, and alcoholamine type buffer into water and mixing to obtain mixed solution 1; adding organic and inorganic composite pour point depressant, non-ferrous metal and ferrous metal composite corrosion inhibitor Add the agent into the mixed solution 1 and mix to obtain the mixed solution 2; add the mold and bacteria inhibitor and the alcohol-modified polyether into the mixed solution 2 and mix to obtain the obtained solution. The product system of the present invention can be rapidly reduced in a low temperature environment after being coagulated.

Description

technical field [0001] The invention relates to a concentrated liquid for a rapid reduction type hydraulic support in a low temperature environment and a preparation method thereof, and belongs to the field of transmission medium for coal mine hydraulic support. Background technique [0002] The hydraulic support transmission medium is known as the "blood" of the hydraulic support, which is very important to the stability and reliability of the operation of the hydraulic support in the coal mine. According to the type of hydraulic fluid with high water content, it is usually divided into two categories: emulsified oil and concentrated liquid. The concentrate for hydraulic support can be dissolved in water to form a liquid substance of solution-type diluent. It is generally composed of water, water-soluble rust inhibitor, anti-corrosion agent, lubricant and other additives. The hydraulic support is composed of high water-containing hydraulic fluid (oil-in-water emulsion com...
