| titleOfInvention | Micro-capsule fire extinguishing agent based on secondary shock wave throwing and preparation method thereof |
| abstract | The invention relates to a fire extinguishing agent, in particular to a microcapsule fire extinguishing agent, and especially relates to a microcapsule fire extinguishing agent sprayed twice by using shock waves and a preparation method thereof. The composition mainly comprises the following components in parts by weight: 5-15 parts of hollow microspheres, 5-15 parts of iodine nitride, 30-50 parts of water, 1-5 parts of a pore blocking agent, 30-50 parts of a solid fire extinguishing powder material and 5-15 parts of a microcapsule material. The fire extinguishing agent has a double-layer microcapsule structure, and microcapsules at the outermost layer can ensure that the physical and chemical properties of the fire extinguishing agent are not damaged before the fire extinguishing agent covers a combustion zone; when the fire extinguishing agent covers the combustion area, the solid fire extinguishing powder material between the two layers of microcapsules starts to play a role in flame retardance; meanwhile, water in the hollow microspheres evaporates to absorb heat, so that the temperature of a combustion area is reduced; when the water is completely evaporated, the iodine nitride in the hollow microspheres is heated and exploded to generate a large amount of nitrogen, the shock wave generated by explosion carries out secondary throwing on the solid fire extinguishing powder material, so that the solid fire extinguishing powder material uniformly covers a combustion area, and the generated shock wave and the nitrogen can weaken combustion reaction and inhibit flame propagation. |
