Abstract

A fire extinguishing composite with a coating of organic materials is provided. The composite comprises metallic salts and organic nonmetallic compounds. The particle size of the metallic salts is micron size or nano size, and the metallic salts are coated by an organic polymer coating layer fabricated by situ-polymerization. The weight ratio of the metallic salts and the organic nonmetallic compounds is 1:0.5-3. The heat and power source of the fire extinguishing composite is pyrotechnic agent, and the high temperature from the pyrotechnic agent combustion is used to decompose the organic nonmetallic compounds and drive the metallic salts coated with organic coating materials releasing so as to extinguish fire rapidly. The fire extinguishing composite can effectively reach the fire source to extinguish fire, improve the extinguishing efficiency, and at the same time make up for the loss of pyrotechnic agent as the cooling layer. The decalescence from the decomposition or sublimation of the fire extinguishing composite reduces the nozzle temperature of the fire extinguishing device.

The traditional physical cooling causes the structure of the device to be complicated and cumbersome, the process flow is complicated, the cost is high, and the physical cooling exists, so that a large number of active particles are inactivated, resulting in greatly reduced fire extinguishing performance. Moreover, the fire extinguishing efficiency is limited, and the cost of the medicament is wasteed to some extent.
