Abstract

The invention discloses a foaming filling reinforced sealing material for coal field fire extinguishing grouting and application thereof, and belongs to the field of grouting materials for coal fieldfire extinguishing. According to the technical scheme, the thermal insulation material comprises 30-35 parts of cement, 10-15 parts of gypsum, 15-20 parts of aluminum oxide, 15-20 parts of fly ash, 15-20 parts of quicklime powder, 3-5 parts of a foaming agent, 1-2 parts of a foam stabilizer, 1-2 parts of a gelatinizing agent, 2-3 parts of a retarder, 1-2 parts of an intumescent flame retardant and1-2 parts of an antistatic agent. The filling reinforcing sealing material is applied to coal field fire extinguishing, overcomes the defects of small expansion coefficient, poor flowability, small fire extinguishing and blocking distance, high after-combustion risk, high cost and low efficiency of an existing filling reinforcing sealing material in coal field fire extinguishing, and has the characteristics of large expansion coefficient, good flowability, large fire extinguishing and blocking distance, low after-combustion risk, low cost and high efficiency.

Description

technical field [0001] The invention belongs to the field of grouting materials for fire extinguishing in coal fields, and in particular relates to a foaming filling reinforcement airtight material for fire extinguishing grouting in coal fields and an application thereof. Background technique [0002] In northern China, especially in Xinjiang, there are more than 100 coalfield fires burning day and night, and about 13 million tons of raw coal are devoured every year. The burning of a large amount of raw coal not only wastes precious natural resources, but also causes environmental pollution and environmental geological problems. The country and various coal enterprises invest a large amount of funds every year to extinguish coalfield fires, but due to the differences in capital investment, regional environment and construction methods, the fire extinguishing effects are also different. Therefore, effective fire extinguishing materials are the key to coalfield fire extinguis...
