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 solution for a rapid reduction type hydraulic support in a low-temperature environment and a preparation method of the concentrated solution. The concentrated solution is prepared from the following components in parts by mass: on the basis that the total mass part number is 100 parts, 5-15 parts of polymeric amino acid; 4-10 parts of a nonionic and anionic composite coupling agent; 2-6 parts of an alcohol amine type buffering agent; 13-30 parts of an organic and inorganic composite pour point depressant; 6.1-13.7 parts of a nonferrous metal and ferrous metal composite corrosion inhibitor; 1-3 parts of a mould and bacterium inhibitor; 1-3 parts of alcohol modified polyether; and the balance of water. The preparation method comprises the following steps: adding the polymeric amino acid, the nonionic and anionic composite coupling agent and the alcohol amine type buffer agent into water, and conducting mixing to obtain a mixed solution 1; adding the organic and inorganic composite pour point depressant and the nonferrous metal and ferrous metal composite corrosion inhibitor into the mixed solution 1, and conducting mixing to obtain a mixed solution 2; and adding the mould and bacterium inhibitor and the alcohol modified polyether into the mixed solution 2, and conducting mixing to obtain the concentrated solution. The product system disclosed by the invention can be quickly reduced in a low-temperature environment after being condensed.

Description

technical field [0001] The invention relates to a concentrated solution for rapid reduction hydraulic supports in a low-temperature environment and a preparation method thereof, belonging to the field of transmission media for coal mine hydraulic supports. Background technique [0002] The transmission medium of the hydraulic support is known as the "blood" of the hydraulic support, which is crucial to the stability and reliability of the coal mine hydraulic support. According to the type of high water-containing hydraulic fluid, it is usually divided into two categories: emulsified oil and concentrated liquid. The concentrate for hydraulic supports can be dissolved in water to form a liquid substance of a solution-type diluent. Generally, it is composed of water, water-soluble antirust agent, anticorrosion agent, lubricant and other additives. The hydraulic support consists of high water-containing hydraulic fluid (oil-in-water emulsion made of emulsified oil and more tha...
