Problems solved by technology

[0005] The disadvantages of the above-mentioned patents are: although the foam multiple of the fire extinguishing agent can reach 20 to 200 times, and the foam stability time is ≥ 2.5 hours, it can only make the "inert gas carbon dioxide foam spread in the fire zone and fill its space in a short time." , so that the oxygen concentration in the fire area drops rapidly, causing the fire area to suffocate due to lack of oxygen", it cannot really isolate the contact between the burning coal seam and the air, prevent the coal mine from continuing to burn, avoid the re-ignition of the coal seam, and achieve flame retardancy and fire prevention. Purpose
Ammonium bicarbonate is used as the main raw material of the fire extinguishing agent. During the fire extinguishing process, a large amount of ammonia gas will be released, which pollutes the air in the mine and is not conducive to the health of operators.

Embodiment Construction

[0049] Below in conjunction with embodiment the present invention will be further described:

[0050] 1. The ingredients of wollastonite reticulated gel foam mud fire extinguishing agent are composed of the following components by weight percentage: 28% wollastonite composite flame retardant foaming agent, 22% inorganic fiber spray cotton mixture and 50% water.

[0051] The production method of wollastonite reticulated gel foam mud fire extinguishing agent: input the ingredients of wollastonite reticulated gel foam mud fire extinguishing agent into the plow mixer, and stir at high speed to form wollastonite reticulated gel Foam mud anti-fire extinguishing agent, the speed of the rake mixer is controlled at 2400-2800 rpm, and the stirring time is controlled at 12 minutes.

[0052] 2. The ingredients of wollastonite composite flame retardant foaming agent are composed of the following components by weight percentage: wollastonite composite flame retardant foaming agent paste 52%...

Abstract

The invention discloses a wollastonite mesh gel foam mud fire prevention and extinguishing agent. The key point of the technical scheme adopted by the invention lies in that the wollastonite mesh gel foam mud fire prevention and extinguishing agent is composed of a wollastonite composite flame retardant foaming agent, attapulgite pottery clay powder with an air purifying function, inorganic fiber spray coating cotton, wollastonite powder, coal gangue powder, expanded perlite powder, sodium alginate and water. The ingredients of the wollastonite mesh gel foam mud fire prevention and extinguishing agent are input into a rake type mixing machine to undergo high-speed stirring, thus obtaining the wollastonite mesh gel foam mud fire prevention and extinguishing agent. The mesh gel foam mud is sprayed to a burning coal layer by an inorganic fiber spray coating machine, thus facilitating generating an integral mesh gel foam mud film in a fire prevention and extinguishing process. The film can always cover and adhere to an ore bed surface to rapidly isolate the burning coal layer from air, prevent coal mine from keeping burning and avoid reburning of the coal layer, thus reaching the purposes of flame retardance and fire prevention and extinguishing. The wollastonite mesh gel foam mud fire prevention and extinguishing agent is suitable for fire prevention and extinguishing of coal mines, other mine operation areas and forests.

Description

technical field [0001] The invention relates to an anti-fire extinguishing agent, in particular to a wollastonite mesh gel foam mud anti-fire extinguishing agent. Background technique [0002] Fully mechanized top-coal caving mining has the advantages of high yield, high efficiency, and low consumption, and has been widely used in many coal production bases in my country. However, due to the high mining intensity of this coal mining method, there is a lot of residual coal left in the goaf, the height of the fall is large, and the air leakage is serious. A series of problems such as fire, gas, and dust that are difficult to solve often occur, especially fire. [0003] Foam fire extinguishing agents are divided into chemical foam, air foam, fluoroprotein foam, aqueous film-forming foam and alcohol-resistant foam. [0004] Chinese Patent Publication No. CN 102614615A, publication date: August 01, 2012, titled "a composite foam fire extinguishing agent for coal mine underground...
