Problems solved by technology

[0002] At present, most of the traditional fire extinguishing systems use smoke sensors. When an open fire is encountered, they are activated manually. This method is not effective. Some fire extinguishing systems also use temperature sensors. When the set temperature is reached, the sensor will feed back the signal to the command center, which will command and start the fire extinguishing equipment to realize fire extinguishing
However, a comprehensive analysis of the current fire extinguishing products in the market, whether gas fire extinguishing devices or aerosol fire extinguishing products, are generally used in fire protection in medium and large spaces. For the protection of fires in small spaces such as household distribution boxes and distribution cabinets, there are generally the following shortcomings: ( 1) The volume is large, the accessory system is complicated, it is not easy to move and carry, and it is only suitable for

Abstract

The invention discloses a self-temperature sensing fire extinguishing composition and a preparation method thereof. Raw materials of the self-temperature sensing fire extinguishing composition comprise the following components in parts by mass: 35-55 parts of labile metal salt, 10-35 parts of organic compound and 1-10 parts of a binder solution. The self-temperature sensing fire extinguishing composition can be triggered by heat released when a fire happens for decomposition reaction, a large amount of gas is generated in the reaction, and fire extinguishing relies mainly on physical containment supplemented by consuming a large amount of burning oxygen in the air in the reaction to block a combustion reaction chain.
