Embodiment 1

[0021]

[0022] First add 20% water into the reaction kettle equipped with a stirrer, stir slowly with a paddle stirrer, the stirring speed is 80rpm, slowly add 15% of rhamnolipid biosurfactant, and slowly add 10% sophorolipid after stirring evenly %, and continue until all the materials are stirred evenly, heat to 80°C in the reaction kettle, and cool to room temperature; add 0.2% sodium alginate to another 10% of water, stir to make it completely dissolved, then add it to the reaction kettle to make up The remaining 44.8% of water is stirred evenly, and the preparation is completed.

Embodiment 2

[0024]

[0025] First add 25% water into the reaction kettle equipped with a stirrer, stir slowly with a paddle stirrer, the stirring speed is 60rpm, slowly add 20% rhamnolipid biosurfactant, and slowly add sophorolipid 13 after stirring evenly %, and continue until all the materials are stirred evenly, heat to 80°C in the reaction kettle, and cool to room temperature; add 0.3% sodium alginate to another 10% of water, stir to make it completely dissolved, and then add it to the reaction kettle to make up The remaining 31.7% of water is stirred evenly, and the preparation is completed.

Embodiment 3

[0027]

[0028] First add 30% water into the reaction kettle equipped with a stirrer, stir slowly with a paddle stirrer, the stirring speed is 60rpm, slowly add 30% rhamnolipid biosurfactant, and slowly add 15% sophorolipid after stirring evenly. %, and continue until all the materials are stirred evenly, heat to 80°C in the reactor, and cool to room temperature; take another 15% of water and add 0.5% sodium alginate, stir to make it completely dissolved and then add it to the reactor to make up The remaining 9.5% of water is stirred evenly, and the preparation is completed.

Abstract

The invention relates to a foam fire extinguishing agent containing biosurfactant and a preparation method thereof. The method mainly solves the problems that the existing foam fire extinguishing agent is easy to pollute the environment and has a short storage time. The foam fire extinguishing agent containing biosurfactant has the following components and proportions by weight percentage: 10%-30% rhamnolipid, 3-15% sophorolipid, 0.1%-0.5% thickener, and The amount is water; the preparation method is: under the condition of stirring, add rhamnolipid into a certain amount of water, stir evenly, add sophorolipid, mix well, heat to 80°C-90°C in the reaction kettle, cool After reaching room temperature, dissolve sodium alginate with 10% water, add it to the reaction kettle, make up the remaining water, and mix well. The foam fire extinguishing agent containing biosurfactant can improve the fire extinguishing performance of the fire extinguishing agent, realize the rapid biodegradation of pollutants in the fire place, and protect the environment.

Description

technical field [0001] The invention belongs to the technical field of biosurfactant application, and in particular relates to a formula and a preparation method of a foam fire extinguishing agent containing biosurfactant. Background technique [0002] Even in countries with a small population, tens of thousands of fires occur every year. The occurrence of fire is a serious problem facing human society. It not only endangers human life and property, but also destroys the environment. When a fire occurs, how to extinguish it quickly and effectively, minimize the loss, the extinguishing ability of the fire extinguishing agent and the method of extinguishing are very important. As a conventional fire extinguishing agent, water-based fire extinguishing agent has been approved and used. Water-based foam fire extinguishing agent is a physical fire extinguishing agent. After spraying the burning material, a fine water mist is formed, which quickly spreads on the fire scene and real...
