Extinguish material, preparation method and application thereof

Abstract

The invention provides a high-efficiency extinguish material for a major fire source, which comprises the following components by weight portion: 1 to 50 portions of component A, 1 to 2 portions of component B, 2 to 1,000 portions of component C, and 0 to 200 portions of component D. The component A is an inorganic silicate material; the component B comprises a foaming agent, a surfactant and a dispersing agent; the component C is water; and the component D comprises a defoamer, a fireproof material, a material generating flame-retardant gas through pyrolysis, a water absorber, a colloidal material and a filling material. The high-efficiency extinguish material overcomes the defects that the prior art has high production and using cost, fast running-off, low service efficiency, severer pollution and high residual quantity, has the advantages of low cost, controllable specific gravity, higher viscosity, difficult seepage, loose storage conditions, fast production, convenient use, safe performance and the like, and can achieve large batches of long-distance transportation. The high-efficiency extinguish material is applicable for large-scale fire extinguishing of oil products, flammable chemicals, large buildings, coal mines, forests and the like, other fire source control and the like.

Description

technical field [0001] The invention relates to a high-efficiency fire extinguishing material for major fire sources, and is especially suitable for fire extinguishing of oil products, flammable chemicals, large buildings, coal mines, forests and other large fires and control of other fire sources. Background technique [0002] Existing fire extinguishing materials mainly contain the following types: [0003] (1) Water. Water is a non-flammable liquid, it is the most widely used in fire extinguishing, and it is the cheapest fire extinguishing agent. The effect of water fire extinguishing is cooling: every kilogram of water temperature rises by 1°C and absorbs 1 kilocalorie of heat; while every kilogram of water vapor absorbs 539.9 kilocalories of heat when vaporized; secondly, water has a diluting effect on oxygen: water meets A large amount of water vapor is generated by the vaporization of the hot burning material, which can prevent the air from entering the combustion z...

AI Technical Summary

Problems solved by technology

Its shortcomings are: the product cost is high, and the use cost is also high; the fire source can only be connected at a short distance, which poses a great threat to the safety of users; the dosage is generally small, and it is not suitable for large-scale fires

Although it is suitable for almost any fire source, it is safe and environmentally friendly, but its disadvantages are: high production and use costs, high storage requirements, difficult to deploy a large number of equipment in the event of a large fire, complex production conditions, and cannot be mass-produced in time. Use Personnel requirements are higher

The advantage is that it has a wide range of applications and low residue; the disadvantage is that the production and use costs are high, and poisonous gas may be produced at high temperature, the social reserve is small, the requirements for production and storage equipment are high, and large-area fires cannot be popularized. Suitable for close use
