Problems solved by technology

And it can only extinguish Class B and Class C fires
[0006] It can be said that the current hot aerosol, aerosol, common ammonium phosphate dry powder fire extinguishing agent, and dry powder cryosol can only reflect a single monomer or have certain defects. In addition, some products have very high production costs and application costs. The application conditions are greatly restricted

Abstract

The invention relates to a multifunctional cold aerosol fire retardant and its manufacture method. The invention is prepared from following raw materials (weight): common ammonium phosphate slat dry powder or monoammonium phosphate in 300-850; isinglass in 10-30; ammonia sulfate in 20-100; carclazyte in 10-30; calcium carbonate in 30-400; white carbon black in 10-100; common salt in 10-50; silicon oil in 5-20; and solvent oil in 5-20. Compared to present technique, the invention has following advantages that: wide fire-extinguishing area; application to A, B, C, D, E type fire hazard; higher fire-extinguishing efficiency, better effect; and high expansion speed. It can avoid after-burning and damage on the human and environment, while the fire-extinguishing concentration is lower to avoid leavings and it has lower cost which is 70-100% lower than present technique, and lower application cost which is 50% lower than present ones.

Description

technical field [0001] The invention relates to the technical field of fire fighting and fire extinguishing, in particular to a multifunctional cold aerosol fire extinguishing agent and a preparation method. Background technique [0002] In the 1980s, scientists first developed a solid sol propellant, and their main research achievement was the development of a synthetic oxygen-containing solid fuel. After the substance is ignited and burned, it is a highly dispersed sol-like powder when the temperature exceeds 300°C, and is evenly distributed in the space to produce a chemical reaction with oxygen to achieve the purpose of quickly and efficiently suppressing fire. This fire extinguishing technology is commonly known as "high temperature fire extinguishing aerosol", also known as "hot aerosol fire extinguishing technology". Thermal aerosol colloidal particles have the characteristics of high dispersion and high concentration. Most of the particles have a diameter of less th...
