Abstract

The invention belongs to the technical field of gas explosion suppression materials, and specifically relates to a gas explosion suppressant and a preparation method thereof. The gas explosion suppressant comprises the following components in parts by weight: 30-70 parts of pseudo-boehmite, 35-55 parts of water glass, 130-150 parts of aluminum sulfate aqueous solution, 100-120 parts of sodium hydroxide aqueous solution, 5-10 parts of metal ruthenium salt and 20-30 parts of nonionic surfactant. The gas explosion suppressant is enabled to rapidly remove gas in an environment and reduce the concentration of the gas through the proportioning of the components and adding for the metal ruthenium salt and the nonionic surfactant; and meanwhile, gas explosion suppressant is further capable of effectively attenuating the shock wave and flame wave of gas explosion, and suppressing the explosion while reducing the concentration of methane, so that the damage brought by the explosion is reduced. In addition, the preparation method does not need a high-temperature environment, and is low in cost.

Description

technical field [0001] The invention belongs to the technical field of gas explosion suppression materials, and in particular relates to a gas explosion suppression agent and a preparation method thereof. Background technique [0002] my country is the world's largest coal-producing country, and coal accounts for about 70% of my country's primary energy consumption. Therefore, the coal industry is an important basic industry related to the lifeline of my country's national economy. However, the coal industry is one of the industries with the most serious safety production situation in my country. Preventing and controlling the occurrence of major accidents in coal mines and promoting the fundamental improvement of the safety production situation in coal mines have become major issues that need to be solved urgently at the national and government levels. The core task of safety production work. Among all coal mine disasters and accidents, gas accidents are the most important,...
