Abstract

The invention discloses a novel environment-friendly fire-retardant concentrated solution for hydraulic supports. The concentrated solution is prepared from the following raw materials in percentage by weight: 10-20% of alizarin oil, 8-15% of acetal monoisopropanolamine, 5-10% of zinc dichromate, 4-10% of sodium ethylenediaminetetramethylene phosphonate, 3-7% of organosilicon quaternary ammonium salt, 2-5% of acetal monoisopropanolamine maleate compound, 2-4% of sodium hydroxide, 0.3-0.5% of polyisobutylene succimide, 0.2-0.4% of titanate coupling agent, 0.1-0.5% of barium naphthanate and the balance of water. The novel environment-friendly fire-retardant concentrated solution for hydraulic supports can satisfy the antirust and anticorrosion requirement of tiny gaps, has the advantages of wide applicability, favorable chemical stability, favorable lubricating property, easy cleaning, no flash point and high safety factor, is degradable, can not influence the environment, obviously enhances the production efficiency, and saves the production cost.

Description

technical field [0001] The invention relates to a concentrated liquid for a hydraulic support, in particular to a novel concentrated liquid for an environmentally friendly and fire-resistant hydraulic support. Background technique [0002] The hydraulic support is an important mechanical equipment used to support the roof in the coal mining face in the coal industry; it is used in conjunction with the shearer, not only to realize the comprehensive mechanization of coal mining, to improve the working efficiency of coal mining and transportation equipment, but also to maximize To ensure the life safety of underground coal mine work. [0003] The hydraulic fluid is used as the transmission medium in the hydraulic support system, and the pressure or kinetic energy of the liquid is used to transmit energy. The lifting, moving and overload protection of the hydraulic support, the transmission of energy, lubrication, reducing the wear and friction of moving parts, preventing rust ...
