Fire preventing and extinguishing rubber material, preparation method and use

Abstract

The invention discloses a fire preventing and extinguishing rubber material which is prepared by mixing 30-100 parts of super absorbent resin, 25-75 parts of inorganic super adsorbent powder, 1-3 parts of suspending agent and 1-6 parts of dispersing wetting agent. The rubber material provided by the invention is used to prevent and treat spontaneous combustion of a coal bed in the form of pouring or spraying, has remarkable fire extinguishing and cooling effects for treating spontaneous combustion of the coal bed in a mine, and has the characteristics of convenience in construction and safety and environmental-friendliness.

Description

technical field [0001] The invention relates to an anti-fire extinguishing material, in particular to an anti-fire extinguishing colloidal material, which is used for preventing spontaneous combustion of coal seams in coal mines. Background technique [0002] my country is rich in coal resources, with large and small coal fields scattered all over the country. Coal is also the most important energy source in my country and occupies a dominant position in the energy structure. This dominant position of coal in my country's energy structure will not change in the next few decades. Therefore, the coal industry is the basic industry of our country, and its healthy, stable and sustainable development is a major issue related to the national energy security. However, with the continuous increase of coal production in my country, the increase of newly built and expanded mines and the increase of mining intensity and mining depth, the problem of mine fire prevention and extinguishin...

Problems solved by technology

[0003] After years of development and application, there are many fire prevention and extinguishing methods in coal mines. The commonly used fire prevention materials and methods include: grouting, pressure equalization, inhibitor, nitrogen fire prevention and extinguishing technology, etc. These methods and technologies play a role in suppressing coal seam spontaneous combustion fire It has a great effect, but there are also some limitations: first, due to the gravity effect of water injection, grouting and spraying of inhibitors, the grout cannot accumulate at high places, and it is difficult to extinguish large-scale fire sources at high places. Effectively reduce the temperature inside the coal block, and the fire re-ignition will be very frequent; second, nitrogen injection and inert foam fire extinguishing need to be tightly sealed and the heat capacity of the gas is small, and the calorific value absorbed inside the coal body is limited

Therefore, the fire extinguishing cycle is long and the probability of re-ignition is high

[0004] In addition, the currently disclosed polymer fire-fighting gels or polymer composite materials generally use a single polymer superabsorbent resin or composite materials without using additives to assist it in dissolving water. During use, high Molecular superabsorbent resin fire-fighting materials tend to form agglomerated insolubles when they dissolve in water and become gels, resulting in a large waste
