Abstract

The invention discloses a special flame retardant used for the fire prevention in forest steppe and a preparation method thereof, wherein the special flame retardant comprises materials according to weight distribution ratio of 10-20 of phosphoric acid, 5-10 of carbamide and 0.04-0.079 of catalyst, and the phosphoric acid and the carbamide are polymerized by the action of the catalyst under the normal atmosphere to prepare powder agent or liquor agent. The special flame retardant has simple device, rapid preparation, convenient use, favorable flame-retarding fire-prevention and emergency fire-extinguishing effects, stronger adhesiveness and penetrability and durable fire-prevention effect. The special flame retardant is pre-sprayed on a fire-prevention strip covered by plants, such as flammable or sear trees, bushes and grassland vegetation, which can prevent fire hazards from happening from the origin; and the special flame retardant can also be confected rapidly into spraying medicament as emergency fire-extinguishing agent or temporary treatment emergency fire-prevention strip. The invention has high stability, environment protection, no toxicity and wide comfort zone, is suitable for territorial environments of different air temperature conditions and has long storage period, wherein, the powder agent can be stored for more than six years and the liquor agent can be stored for more than three years.

Description

technical field [0001] The invention relates to a preparation and a preparation method for preventing the occurrence of forest and grassland fires in advance, delaying and preventing the spread of forest and grassland fires, and emergency fighting forest and grassland fires. Background technique [0002] According to statistics, there are more than 220,000 forest fires in the world every year, with a total area of ​​300 million to 400 million hectares burned, more than 6.4 million hectares of forest burned, and about 9 billion tons of plant biomass burned. The recent forest fires in Greece, the United States, and Australia have caused huge property losses and major international impacts, with direct economic losses of billions of dollars, affecting the normal production and life of millions of people, and causing immeasurable ecological disasters. Especially in the past ten years, affected by factors such as climate warming, the frequency and degree of damage of forest fires...
