preparation example Construction

[0043] The preparation method of the water-based fire extinguishing agent of the present embodiment comprises the following steps: 1) uniformly mixing a hydrocarbon surfactant, a flame retardant and water to obtain a flame retardant liquid; mixing a fluorocarbon surfactant, a tackifier, and a stabilizer 1. Mix the antifreeze agent and water evenly to prepare the glue; 2) mix the flame retardant solution prepared in step 1) and the glue evenly to prepare the mother liquor, and dilute the mother liquor to obtain the product.

[0044] In the step 1), the hydrocarbon surfactant, the flame retardant and water are uniformly mixed. First, the hydrocarbon surfactant and water are uniformly mixed, and then the flame retardant is added and mixed uniformly to obtain a flame retardant liquid. In step 1), the hydrocarbon surfactant and water are uniformly mixed by mixing the hydrocarbon surfactant and water at a speed of 2000-3000rpm and stirring for 1-2-3min. After adding the flame retard...

Abstract

The invention discloses a water-based fire extinguishing agent and a preparation method thereof and a fire extinguisher, and belongs to the technical field of fire-fighting equipment. The water-basedfire extinguishing agent is mainly prepared from the following raw materials in parts by weight: 3.1 to 4.5 parts of a hydrocarbon surfactant, 1.2 to 1.8 parts of a fluorocarbon surfactant, 1.85 to 2.2 parts of a tackifier, 0.72 to 0.85 part of a flame retardant, 1 to 2 parts of an anti-freezing agent, 1.5 to 1.8 parts of a stabilizer and 610 to 820 parts of water. The flame retardant is at leastone of melamine cyanurate, aluminum hypophosphite, aluminum diethyl phosphinate, ammonium polyphosphate, aluminum hydroxide and zinc borate. According to the water-based fire extinguishing agent, thehydrocarbon surfactant and the fluorocarbon surfactant are added, the synergistic effect of the hydrocarbon surfactant and the fluorocarbon surfactant can be brought into full play, precipitation of the surfactants is avoided, the uniformity and stability of the fire extinguishing agent are improved, and the burning resistance of the fire extinguishing agent is improved to a certain extent.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, and more specifically, relates to a water-based fire extinguishing agent, a preparation method thereof, and a fire extinguisher. Background technique [0002] Fire will cause huge losses to people's lives and property. At present, with the rapid growth of urban population density, people's various activities have greatly increased the risk of fire. How to reduce the probability of fire or reduce the damage of fire is the city's development. important question. To avoid the occurrence of fire, it is necessary to strengthen the safety and flame retardancy of buildings and devices. If a fire occurs accidentally, it is best to extinguish the fire source in time at the beginning of the fire to eliminate the fire in the cradle stage; if the fire spreads, effective means are needed to control the fire. Fire extinguishers and large-scale fire-fighting equipment are commonly used fire-fi...
