Problems solved by technology

The Chinese patent 200710018218 drug mixing method is to mix all the components into a suspension in an organic solvent. The uniformity of mixing still depends on the degree of crushing of the material, and the use of organic solvents has a greater impact on the environment and higher costs.
And the organic solvent added in the process only plays a role of dispersing, and the components are not dissolved, so the mixing effect still depends on the diameter of the original material particles, affected by the limit of mechanical grinding, it is impossible to achieve greater mixing uniformity breakthrough

Abstract

The invention relates to a solid sol type aerosol fire extinguishing agent and a preparation method thereof. In the preparation method, water is adopted as a solvent, an oxidant and a reducing agent which are easy to be soluble in the water are used as raw materials, the oxidant and the reducing agent are uniformly dispersed at the molecular level, the preparation method realizes larger breakthrough on medicament mixing uniformity than that of a grinded dry mixing method, and the combustion performance and the fire extinguishment of a product are obviously improved. The method reduces a process of pulverizing the raw materials, improves the material flowing speed in a production process, realizes high yield, can reduce production energy consumption and production cost to a greater degree, avoids dust pollution, realizes the safety and the environmental protection of the production process and can be used as a Halon alternative technology.

Description

[0001] Field: [0002] The invention belongs to the technical field of fire fighting and fire extinguishing, and relates to a solid sol type aerosol fire extinguishing agent and a preparation method thereof. Background technique: [0003] After my country signed the Montreal Protocol, it formulated the national "Halon Overall Phase-Out Plan", which established the big goal of completely stopping the production and use of halon fire extinguishing agents (the main substance that destroys the ozone layer) on December 31, 2010. On August 1, 2001, the Ministry of Public Security issued the "Notice on Further Strengthening the Management of Halon Substitutes and Their Alternative Technologies", which further clarified the basic principles for promoting halon substitutes, and stipulated that aerosol and water mist fire extinguishing systems Five types of fire extinguishing technologies are listed as halon replacement technologies popularized and used by the state. [0004] Aerosol f...
