Abstract

The invention discloses a fire-fighting material with excellent smoke suppression for spraying in a coal mine and a preparation method thereof, and belongs to the technical field of the fire-fighting material. The fire-fighting material is prepared from the components by weight percent: 60-80% of polyving akohol flame-resistant material and 20-40% of ammonium molybdate, which are mutually mixed and evenly stirred, wherein the polyving akohol flame-resistant material is prepared from 3-7% of polyving akohol, 1-4% of phosphoric acid, 1-4% of urea, 8-25% of white emulsion, 17-33% of inorganic aggregate and running water in a reaction manner; and the inorganic aggregate is one or any combination of more of kaoline, talcum powder and mica powder. By adopting the method, the smoke suppression of the material is greatly improved; and only a trace of smoke is generated in a combustion process.

Description

technical field [0001] The invention relates to a spray-coated anti-fire extinguishing material for coal mines with excellent smoke suppression performance and a preparation method thereof, belonging to the technical field of anti-fire extinguishing materials. Background technique [0002] my country's coal occupies a dominant position in China's energy structure, which has great strategic significance for our country and has brought huge benefits to the country and the people. However, the conditions in my country's coal mine field are complex and the environment is harsh, and various accidents will cause huge losses to the country every year. Economic and property losses, these accidents have brought great physical and psychological harm to people. After the coal seam is mined, the air volume exchange between the ground and the air inlet roadway, between the air inlet roadway and the return air roadway, and between the air return roadway and the ground gradually increases, ...
