The invention discloses a fire extinguishing agent special for forest and grassland in the technical field of fire extinguishing agents for forest and grassland. The fire extinguishing agent comprises the following components in parts by weight: 2-3.5 parts of a surfactant, 60-75 parts of a high-concentration flame retardant, 1-2 parts of a high-strength penetrant, 0.5-1.0 part of a composite thickener, 3-5 parts of a stabilizer, 0.5-1 part of a crosslinking aid, 2-4 parts of a hydrophobic component, 1-2 parts of an anti-blocking agent and 15-20 parts of deionized water. According to the fire extinguishing agent special for the forest grassland, the added high-strength penetrating agent and the added composite thickening agent can be attached to the periphery of the grassland, so that the fire extinguishing agent is not prone to being blown away by air waves or strong wind formed by big fire, the fire extinguishing agent can directly reach the root of a fire source, the fire extinguishing speed and efficiency are improved, the using amount of the fire extinguishing agent is reduced, and the fire extinguishing cost is reduced; and ammonium dihydrogen phosphate is added as a flame retardant, so that re-combustion of a forest fire can be effectively prevented, or the re-combustion time of the forest fire can be remarkably prolonged, and more time is provided for manually cleaning a fire scene to ensure that the forest fire is completely extinguished.

The invention discloses a high-water-quick-setting foaming material for preventing and extinguishing fire and a preparation method thereof. The high-water-quick-setting foaming material comprises a component A, a component B and a component C, the component A consists of sulphoaluminate cement, phosphogypsum, an accelerator A, a retarder and a suspending agent in a mass ratio of 10: (2-4): 0.03: 0.05: 0.05; the component B is prepared from Portland cement, ardealite, an accelerator B, a retarder and a suspending agent in a mass ratio of 10: (1-3): 0.03: 0.05: 0.05; the component C is composed of a foaming agent and a foam stabilizer in a mass ratio of 1: 0.01; the component A, the component B and the component C are respectively mixed with water according to a water-cement ratio of (3-6): 1, and then are mutually mixed to prepare the high-water-quick-setting foaming material. The material not only has dual effects of fire prevention and fire extinguishment, but also has the advantages of high condensation speed, high consolidation capacity, good air leakage stoppage effect and capability of longitudinally stacking and inerting a target fire area, and the fire prevention and extinguishment effect of a mining area is ensured.
