Embodiment 1

[0028] As a preferred embodiment of the present invention, a novel fire extinguishing material and preparation method thereof are disclosed. In this embodiment, the raw material of the fire extinguishing material includes ore soil, and the preparation method of the fire extinguishing material comprises the following steps:

[0029] Step 1: Crushing and grinding the ore soil, filtering with a 100-mesh sieve, and weighing to obtain 10KG powder;

[0030] Step 2: Add 25L of concentrated sulfuric acid with a concentration of 98% to the powder, stir evenly, add 20L of concentrated hydrochloric acid with a concentration of 38%, continue stirring, add 10L of hydrogen peroxide with a concentration of 90%, and continue stirring for three hours to obtain the first reaction thing;

[0031] Step 3: After leaving the first reactant for half an hour, pour out the solution, wash the powder three times with 5L of deionized water per kilogram of powder, and dry to obtain the intermediate powder...

Embodiment 2

[0037] As a preferred embodiment of the present invention, a new type of fire-fighting and fire-extinguishing material and its preparation method are disclosed. In this embodiment, clay is used to replace the ore in Embodiment 1, and other steps are consistent with Embodiment 1.

Abstract

The invention discloses a new fire extinguishing material for fire fighting and a preparation method thereof, wherein the fire extinguishing material includes raw materials of mineral earth and clay,and is prepared through steps of: crushing, impurity removal, acidity reduction, drying, surface modification, water washing to neutral, filtration, drying, milling, and wet milling, thereby forming asuspension liquid capable of being used for preparing the fire extinguishing material. By means of the mineral earth and clay, the main components in the fire extinguishing material are all natural minerals, so that the material is low in cost and is toxic-free and harmless, is free of adverse effect on environment; meanwhile, the material is free of forming harmful substances during the fire fighting and is great in practicability.

Description

technical field [0001] The invention belongs to the field of fire extinguishing materials, in particular to a novel fire extinguishing material and a preparation method thereof. Background technique [0002] Fire prevention and flame retardancy have always been an important topic for human beings to prevent natural disasters and protect themselves. Water and sand are the most primitive fire extinguishing materials, and later there are other types of fire extinguishing materials, namely: water-based fire extinguishing agent, dry powder fire extinguishing agent, foam fire extinguishing agent, gas fire extinguishing agent, and non-combustible organic liquids such as halogenated alkanes class of fire extinguishing agents. The fire extinguishing and flame retardant properties of these materials have their own advantages and disadvantages, but they are not applicable in some cases, such as: power battery fires, after the power battery catches fire, the combustion of the battery i...
