Abstract

The invention relates to a low-temperature-resistant premixed foam fire-extinguishing agent and a preparation method thereof, and mainly solves the problem that fire-fighting chemicals cannot be used in a low-temperature environment after being mixed with water in the prior art. The problem is solved well through adopting the technical scheme that the low-temperature-resistant premixed foam fire-extinguishing agent and the preparation method thereof are adopted, and comprises the following components in percentage by mass: 10-20% of pour point depressant, 0.1-1.0% of film-forming agent, 0.5-2.0% of foaming agent, 0.05-0.2% of penetrating agent, 0.2-1.0% of foam-stabilizing agent, 0.1-0.5% of preservative, 2-5% of other additives and the balance deionized water. A fire extinguisher or a fire-extinguishing device can be directly filled with the low-temperature-resistant premixed foam fire-extinguishing agent in the low-temperature environment to extinguish fire.

Description

technical field [0001] The invention relates to a low-temperature resistant premixed foam fire extinguishing agent and a preparation method thereof. Background technique [0002] When a fire breaks out, various fire extinguishing devices play a huge role. Among the existing fire extinguishing devices, foam fire extinguishing devices have a wide range of applications. In addition to fixed and semi-fixed foam fire extinguishing devices, mobile foam devices (series of foam fire extinguishers and devices, etc.) widely recognized. However, most of the fire extinguishing agents used in this series of products are diluted with foam liquid stock solution and then directly filled in containers for use. Even if the freezing point of the foam liquid stock solution itself reaches -40°C, it will be diluted with water to the use concentration, such as 3% foam Fire extinguishing agent, when using, add 97 parts of water to 3 parts of foam fire extinguishing agent; 6% type foam fire exting...
