Preparation method of self-temperature sensing type fire extinguishing patch and self-temperature sensing type fire extinguishing patch prepared by reparation method

Abstract

The invention discloses a preparation method of a self-temperature sensing type fire extinguishing patch and a self-temperature sensing type fire extinguishing patch prepared by the reparation method.The preparation method of the self-temperature sensing type fire extinguishing patch comprises the following steps that (a) a fire extinguishing composition is prepared, specifically, (a1) by weight,25-55 parts of easily decomposable metal salts, 10-35 parts of organic compounds and 1-10 parts of adhesive solutions are weighed and taken, wherein all other components except the adhesive solutionsare weighed after drying and crushing; (a2) the other components weighed in the step (a1) except the adhesive solution are uniformly mixed; (a3) the adhesive solutions weighed in the step (a) is added into the components in the step (a2), and uniformly mixing is carried out to obtain the fire extinguishing composition; (b) a fire extinguishing composition is arranged on the carrier patch in a pouring mode; and (c) the carrier patch is dried or aired to obtain the self-temperature sensing type fire extinguishing patch. The self-temperature sensing type fire extinguishing patch can be triggeredat the initial stage of a fire, so that a large amount of gas is released to effectively extinguish the fire and the loss is further reduced.

Description

technical field [0001] The invention relates to a preparation method of a self-sensing temperature-type fire extinguishing sticker and the self-sensing temperature-type fire-extinguishing sticker, belonging to the field of fire-fighting and fire-extinguishing technical products. Background technique [0002] 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 use temperature sensors. When the temperature is set, 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 spa...

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.
