Self-temperature sensing fire extinguishing composition and preparation method thereof

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.

Description

technical field [0001] The invention relates to a self-heating type fire extinguishing composition and a preparation method thereof, belonging to the field of fire extinguishing technical products. Background technique [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.

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 large-area space use, and it is powerless for small-area fires; (2) The aerosol fire extinguishing device belongs to the submerged fire extinguishing method. When a small fire or initial fire occurs, the entire system will be activated, causing the entire space to be damaged by the fire extinguishing agent, resulting in large losses; (3) Traditional gas fire extinguishing devices need to be equipped with storage pressure bottles to ensure fire extinguishing efficiency, and need to be stored in a place that is easy to trigger Arrange detection and feedback devices at the fire point, which is costly and has high safety risks for pressure vessel equipment

Although fire extinguishing is efficient and rapid, due to the high temperature required for triggering, the fire is often out of control before it is triggered, and the loss cannot be effectively reduced, so that the fire can be effectively contained and extinguished at the initial stage.
